Background

Wool is an important raw material for the textile industry, and the most widely used is sheep wool, commonly called wool or wool fiber, which has high water absorption, is comfortable to wear, can form many non-flowing air spaces as barriers due to its natural crimp, has good heat retention, and has excellent stretch and elastic recovery properties, and is durable.

Meanwhile, under the condition of damp heat, the wool fibers are repeatedly acted by mechanical external force, and the fiber assemblies gradually shrink and become compact, are mutually interpenetrated and entangled, and are interwoven and felted. This property is called the felting (also called felting) of the wool fibres. The felting property is caused by the poor micro-friction effect that the friction coefficient of the positive scale of the wool fibers is smaller than that of the negative scale.

The felting property is the biggest characteristic of the wool fabric, when the wool fabric is repeatedly rubbed by mechanical external force, the wool fabric generates the trend of unidirectional movement pointing to the fiber root end, and in addition, the wool has excellent extensibility, rebound resilience and space curling, so that the wool fiber is easy to move, the wool fiber is subjected to cross knitting and felting, the wool end is gradually exposed on the surface of the fabric, the fabric becomes excellent in appearance, thick in hand feeling, soft in texture and good in heat preservation effect. However, the existence of the fulling property also causes the size instability of the fabric (which is common in life, the woolen sweater is easy to shrink and the size of the woolen sweater is reduced after being washed).

In order to improve and enhance the internal quality and appearance effect of wool fabric, generally, a felting treatment is often required in the wool fabric manufacturing process to ensure that the fabric has compact texture, shortened length, increased square meter weight and thickness, enhanced strength and enhanced elasticity and heat retention, and a layer of fluff is exposed on the surface of the felted wool fabric to ensure that the wool fabric has beautiful appearance, thick and soft hand feeling and soft color, and in addition, the fluff generated by felting plays roles in fading and covering certain original defects of the wool fabric so as not to obviously expose on the surface of the fabric.

The conventional fulling method comprises spinning wool, weaving or weaving into a piece or cloth, fulling and then making into garment, and also comprises fulling wool directly. In the prior art, few reports are related to direct fulling of ready-made clothes. The prior patent document 1 of the applicant discloses a fulling method of wool knitted garment, namely washing the wool knitted garment by using heat treatment liquid, wherein the washing temperature is 68-75 ℃, and the bath ratio is controlled to be 1: 20-30; through the accurate regulation and control of the washing temperature and the washing time, the wool strongly-shrunk knitted fabric which has high shrinkage rate, can realize stable shrinkage in the transverse direction and the longitudinal direction and in each accessory can be obtained, the product quality is good, the format size accuracy is high, the specification size deviation is +/-1.0 cm, and the product yield can reach more than 99%.

Consumers demand not only good patterns and warmth but also beautiful and various patterns of externally worn knitted fabrics, for example, knitted fabrics having different textures are favored by more and more people. However, the wool fabric pieces with different tissue structures have different external forces on wool, the fabric structures have different felting degrees (or felting effects) under the same temperature and other felting conditions, the fabric piece retraction rate of part of the tissue structures is small, the fabric piece retraction rate of part of the component structures is large, when the finished clothes are directly subjected to fulling, the smoothness of the sleeve opening sewing part can still be ensured after fulling by realizing the fabric pieces with different tissue structures, the accuracy of the size version is ensured, and meanwhile, the heat retention property can be kept, so that the great challenge is achieved.

< wool knitted Fabric with locally Strong fulling >

In the invention, "local strong fulling" means that the area shrinkage of part of the weave structure of the wool knitted fabric after fulling treatment is not less than 30%. In some embodiments of the present invention, the "partially-shrunk" wool knitted fabric refers to a ready-made garment having two or more weave structures, wherein the area shrinkage of the three-flat weave part after the shrinking treatment is not less than 30% to achieve the effect of strong shrinkage, and the area shrinkage of the other weave part is not more than 10%, so that the phenomenon of partial strong shrinkage of the ready-made garment is achieved, and the rest part basically keeps the original state. In other embodiments of the present invention, the "partially veloped" wool knit also includes all the weave structures that make up the wool knit having an area shrinkage of no less than 30%, but the difference in area shrinkage of the different weave structures.

The wool knitted fabric of the invention comprises at least two weave structures. In some embodiments of the invention, the wool knit according to the invention comprises a total of two weave structures, such as a tri-planar weave and a hank weave or a tri-planar weave and a rib weave. In other embodiments of the present invention, the wool knitted fabric of the present invention comprises three weave structures.

Generally, knitted fabrics are classified into a basic structure and a pattern structure, the basic structure includes a weft plain structure (also referred to as a plain structure, such as a single-side weft plain structure (hereinafter referred to as a single-side structure), a cylinder (double-side plain) structure), a rib structure (such as a 1+1 rib, a full stitch, and a quarter stitch), and a reversible structure, and the pattern structure includes a jacquard structure, a tuck structure, a transfer structure (such as a picking structure and a twisting structure), a loop structure, a wave structure, a weft-added structure, and an air layer structure (such as a quarter-flat idle structure, and a triple-flat structure).

In order to obtain a locally strong fulling effect and ensure warmth retention, the present invention wherein the first tissue structure is a tri-planar tissue. The tri-planar histology is named as a rib semi-air layer and consists of four flat lines in a transverse row and a flat needle in a transverse row. The three-plane weave fabric has different densities and appearances on two sides, has larger extensibility than the four-plane weave fabric, soft hand feeling and thicker gray fabric.

The present inventors have found that a three-dimensional flat structure and a single-sided structure have a relatively large shrinkage rate, but the three-dimensional flat structure has a larger shrinkage rate and is more stable, and that an air layer can be formed in a fabric by alternately knitting and compounding the three-dimensional flat structure on front and back needle beds, and that a fabric sheet having such a structure is more compact and thick and has better heat retention than a single-sided structure fabric. The first weave structure of the present invention is therefore a tri-planar weave, which is the key weave structure of the partially veloped fleece knitted fabric of the present invention, and in some embodiments of the present invention, the "local velocimetry" of the present invention refers primarily or substantially to the location of the tri-planar weave after velocimetry. In the present invention, in order to ensure better warmth retention, the tri-planar weave may be more than 50%, more preferably more than 70%, and still more preferably more than 80% of the total area of the knitted wool fabric of the present invention, and other weave structures having a relatively small shrinkage may be used in the neckline, cuffs, front panel, and the like to enhance the aesthetic property.

In order to ensure the smoothness of the collar part after the fulling of different tissue structures, the invention also carries out deep research on the fulling effect of the fabric pieces with different tissue structures, relatively speaking, the shrinkage rates of rib weave, four-flat weave, shrink-proof yarn fabric, jacquard weave and the like are relatively small, and the shrinkage rate of three-flat weave is large. In the invention, before the garment fulling process, the looping density in the length direction of the three-flat tissue is 20-80 turns/needle of other tissue structures corresponding to every 104 turns of the three-flat tissue, and further 25-75 turns/needle of other tissue structures. The pocket density in the length direction of the tri-planar tissue of the present invention refers to the ratio of the number of turns of the tri-planar tissue before fulling to the number of turns of the other tissue in the case where the finished products have the same length. For convenience of use, the number of rotations before milling is quantified as 104 for milling the other tissue corresponding to the three-phase tissue before milling. Because the knitting structure has certain elasticity, the matching range of the knitting structure and the knitting structure can float up and down, but if the matching revolution number is too large, the finished product after fulling is not smooth. When the sewing machine is used, whether the two tissues are easy to penetrate through the needle of the disc machine according to the matching density when the grey cloth is sewn or the looping machine is used for looping is also considered.

The other structures of the present invention are not particularly limited. In some embodiments of the invention, the other tissue structures of the invention have different retractions than the tri-planar tissue, and further, the other tissue structures of the invention are selected from rib tissue, twisted tissue, ribbed tissue, jacquard tissue, and/or single sided tissue. Still further, other tissue structures of the present invention have a relatively low retraction rate compared to tri-planar tissue. Considering different texture structures, when other texture structures are selected from rib textures, the sleeve opening density in the length direction of the three-flat textures is 30-39 turns before a garment milling process, and furthermore, the rib textures are 32-38 turns corresponding to every 104 turns of the three-flat textures. The other tissue structure is selected from rib tissue, the pocket density before the garment fulling process is that the length of per 104 turns of the three-dimensional tissue corresponds to the width of 65-80 needle rib tissue, and further the length of per 104 turns of the three-dimensional tissue corresponds to the width of 68-75 needle rib tissue. When other tissue structures are selected from single-sided tissues or twisted tissues, the sleeve opening density in the length direction of the three-dimensional tissues before the garment milling process is 20-32 turns, and furthermore, 25-30 turns of rib tissues are corresponding to every 104 turns of the three-dimensional tissues.

< method for producing wool knitted fabric having strong localized fulling >

The preparation method of the wool knitted fabric with the local strong fulling comprises a spinning process, a weaving process and a garment fulling process. The procedures can adopt the conventional method in the field, but in order to ensure the effect of the final product, the key parameters of each procedure need to be controlled.

For the spinning process involving the tri-planar structure, it is preferable to use fine wool having a wool fineness (i.e., the size of the cross-sectional diameter of the wool fibers) of 24 μm or less and a natural wool tuft length of 5.5 to 12cm, such as Australian merino wool, domestic fine wool such as Xinjiang fine wool. Further, the Australian merino wool is preferable from the viewpoint of the stability of fulling. Australian Meilino wool (merino wool), also known as Meilino or merino wool, is a broad-term Meilino fine wool, preferably having an average fineness in the range of 18.1 to 21.5 μm, more preferably 80 wool tops, having an average fineness of about 18.5 μm, is used in the present invention. Further, the Australian merino wool with the fiber fineness of 18.5 +/-0.3 mu m and the tuft length of more than 85mm is preferably adopted for spinning to obtain the yarn, and the yarn is dyed according to needs. The thickness of the yarn has a certain influence on the fulling effect. Further preferably, the ready-made clothes woven and sewn by single yarn yarns with 25 and 44 metric counts are more stable in shrinkage rate by the fulling method, higher in plate size accuracy and +/-1.0 cm in specification size deviation, wherein the size deviation in the length direction (clothes length, sleeve length, skirt length and trouser length) of 60cm or more is not more than 1.0cm, and the size deviation in the width direction (1/2 chest circumference, 1/2 waist circumference and shoulder width) of 60cm or less is not more than 0.5 cm. Furthermore, the inventor finds that the shrinkage rate of the three-phase weave piece woven by the single yarn with 44 metric counts is more stable.

For spinning processes involving other weave structures, wool with a low shrinkage rate, such as shrink-proof wool, may be used.

The weaving process of the present invention refers to a process of weaving yarns to obtain a fabric sheet, and the weaving process of the present invention includes preparing a triplanar fabric sheet. Considering that the density of the weaving piece is a key factor for ensuring the conformity of the specification and the size of the finished product and the weight design of the product, the size control of the machine unloading is mainly carried out by the pulling density and the gross length, and the pulling density is usually measured after being pulled apart by hand. In order to obtain the tri-planar tissue piece with more stable retraction rate, the front surface of the tri-planar tissue piece obtained by weaving is preferably 2.2-2.8cm/8, and the back surface of the tri-planar tissue piece is 2.1-2.5cm/10 meshes, and further, the front surface of the tri-planar tissue piece is 2.4-2.8cm/8, and the back surface of the tri-planar tissue piece is 2.2-2.4cm/10 meshes. "front side draw-down of 2.2-2.8cm/8 counts" means that the fabric is pulled off in the cross direction, measuring the length of 8 knitted fabric to be 2.2-2.8 cm. "reverse bulk 2.1-2.5cm/10 mesh" means that the reverse side of the fabric is pulled apart longitudinally and the length of the 10 rows of fabric is measured.

In some embodiments of the present invention, the size of the three-dimensional flat tissue piece obtained by weaving is (280-350) x (180-250) needle, and further (280-320) x (180-220) needle. The density of the fabric pieces of other weave structures is not particularly limited.

Further, in order to control the fulling effect more accurately, the invention carries out preshrinking experiments on the fabric slices made of each batch of yarns so as to determine the specific washing temperature and washing time when the wool knitted garment is fulled. The preshrinking experiment refers to the process of selecting an experimental fabric piece (the size is preferably 500mm multiplied by 500mm) and putting the experimental fabric piece into an industrial washing machine for washing and fulling, and the invention determines proper washing temperature and time by measuring the sizes of the experimental fabric piece before and after fulling and calculating the area shrinkage. The area shrinkage of the tri-planar tissue piece is preferably controlled to be 30-50%, preferably 30-48%, and more preferably to be about 45% to determine the optimum washing temperature and washing time, so as to guide the subsequent fulling process of the wool knitted garment under the same bath ratio.

The invention utilizes the weaving process to obtain the knitted piece, and then the knitted piece is sleeved and sewed to obtain the ready-made clothes. The sewing of the weaving piece (or the cloth piece) mainly adopts a disc sewing machine. Different from the common sewing by a sewing machine, the cuff sewing enables the splicing part of the fabric pieces to have certain elasticity, and the manufactured ready-made clothes have good containing property and extensibility. The invention has certain requirements on the cuff density (the ratio of the cuff circumference before fulling) so as to more easily obtain the wool knitted fabric with smooth cloth surface, particularly the cuff seam.

And starting the garment fulling process to further obtain the wool knitted fabric with locally strong fulling. The garment fulling process comprises the steps of washing wool knitted garments obtained by sewing knitted pieces with different tissue structures through a looping by using heat treatment liquid, controlling the washing temperature to be 50-75 ℃, controlling the bath ratio to be 1:20-30, washing for 10-30 minutes, dewatering after washing, and drying to obtain the wool knitted fabrics with local strong fulling. In order to further reduce the energy consumption, the inventor researches the fulling condition of different textures, and further finds that for wool knitted ready-made clothes with different textures, the washing temperature can be properly reduced on the basis of patent document 1, but the washing temperature is not too low, otherwise the fulling is incomplete, and the thickness of the ready-made clothes is not uniform, and the washing temperature is 50-75 ℃, preferably 52-70 ℃. The temperature of the heat treatment liquid of the invention determines the washing temperature, the heat treatment liquid mainly takes hot water as main material, therefore, the temperature of the hot water, namely the washing temperature, can be selectively added with 2 to 3 small amounts of washing aids, such as smoothing agent, softening agent and the like, and the addition of the washing aids is mainly used for improving the hand feeling of fabrics. Smoothing agents, softeners, which may be silicone based smoothing agents, collagen softeners, and the like, are commonly available commercially. In one embodiment of the present invention, the smoothing agent and the softening agent are added in an amount of 1 to 3:1000, preferably 1 to 2:1000, more preferably 1:1000, relative to the total weight of the hot water, without limitation. The washing temperature and the washing time of the invention are mainly determined by the preshrinking experiment of the woven piece obtained in the weaving process, and the washing time also comprehensively considers the weight of the ready-made clothes in the industrial automatic washing machine, and the washing time is usually 10-30 minutes, and further 15-25 minutes. The bath ratio is controlled to be 1:20-30, and the non-uniform fulling is easy to occur when the bath ratio is too large, the material consumption is too much, and the bath ratio is too small. In the invention, the processes of dehydration, drying and the like after washing have little influence on the retraction rate, the dehydration and the drying are both carried out by adopting the conventional method in the field, the dehydration is generally carried out for 5 to 10 minutes, the drying temperature is controlled to be 70 to 80 ℃, the temperature is too low, the drying is incomplete, the temperature is too high, and the ready-made clothes can be coked. After drying, simple high temperature ironing can be carried out as appropriate to ensure the plate shape. After the fulling process, the average area shrinkage of the three-planar-structure knitted piece in the wool knitted garment is more than 30%, and in some embodiments of the present invention, more than 45%.

In addition, the invention also provides the wool knitted fabric with local strong fulling prepared by the preparation process. The wool knitted fabric with the locally strong fulling comprises wool overcoat, trousers, a skirt, a woolen sweater, a scarf and the like which are suitable for being worn outside.

The invention is further illustrated, but not limited, by the following examples.

Examples

The present invention is described below by way of examples, which are not exhaustive, as those skilled in the art will appreciate that the examples are illustrative only.

The shrinkage is measured according to GB8628-88 test standard and method, because the size or area of the fabric or garment is reduced after the shrinkage, the absolute value of the size change percentage in the standard is taken as the shrinkage of the invention, and the reduction value is divided by the original value to obtain the shrinkage.

Australian merino wool with the fiber fineness of 18.5 +/-0.3 mu m and the hair bundle length of more than 85mm is used as a raw material. 2/44NM (2 ply 44 metric count) wool is adopted to weave a three-plain weave piece with 2.5cm/8 count on the front surface, 2.3cm/10 mesh on the back surface and 300 turns x 200 needles on a 12-needle flat knitting machine by using 1 yarn. The prepared three-dimensional woven piece is 41cm long in lower machine size and 41cm wide, is put into an industrial washing machine and is washed by hot water at 55 ℃ for 15 minutes at a bath ratio of 1:25, the woven piece is taken out on time, is dehydrated for 5 minutes, is then put into an oven at 75 ℃ for drying, is then put on a platform, is observed in appearance, measures the length and the width of a finished product, and calculates the area retraction rate.

The 20 weaves were tested repeatedly and the area retraction rate was calculated as shown in table 1.

TABLE 1 milling of Tri-planar tissue

1+1 rib weave structure

Australian merino wool with the fiber fineness of 18.5 +/-0.3 mu m and the hair bundle length of more than 85mm is used as a raw material. 2/44NM wool is used for weaving a 1+1 rib weave structure with the size of 100 turns multiplied by 150 needles on a 12-needle flat knitting machine, and the rib weave structure is drawn densely to 3cm/6 (6 rows of wale stitches, the drawn width is 3cm under the action of certain drawing force). The prepared 1+1 rib weave structure fabric piece is 20cm long in the lower machine size and 12cm wide, the fabric piece is placed in an industrial washing machine and washed by hot water at 55 ℃ for 15 minutes at a bath ratio of 1:25, the fabric piece is taken out on time, the fabric piece is dehydrated for 5 minutes, then the fabric piece is placed in an oven at 75 ℃ for drying, then the dried fabric piece is placed on a platform, the appearance of the dried fabric piece is observed, the length and the width of a finished product are measured, and the area retraction rate is calculated.

Tri-planar tissue and twisted tissue collocation

Australian merino wool with the fiber fineness of 18.5 +/-0.3 mu m and the hair bundle length of more than 85mm is used as a raw material. 2/44NM wool is used to weave a three-piece fabric with 1 yarn on a 12-needle flat knitting machine, the front surface of the fabric is drawn and compacted to be 2.5cm/8, the back surface of the fabric is drawn and compacted to be 2.3cm/10 meshes, and the size of the fabric is 300 turns multiplied by 200 needles. Another twisted piece is prepared, a piece of 2/48NM shrink-proof wool is used for weaving a piece of 34 needles by 58 turns on 6 yarns on a 7-needle flat knitting machine, the row needles are shown in a row needle diagram of fig. 5, and the outer edge of 4 drawn and dense drawn needles is drawn by 5cm (the width of a column between the 2 nd row needle and the 5 th row needle of an upper needle bed on the row needle diagram is drawn by a certain tensile force to be 5 cm).

The prepared three-woven piece had a lower machine size of 47cm in length and 34.7cm in width, and had a lower machine vertical density of 6.38K/cm (lower machine vertical density: number of woven piece revolutions/lower machine length) and a lateral density of 5.76N/cm (lower machine lateral density: number of woven piece needles/lower machine width). The matched twisted pieces (with the lower machine length of 21.8cm and the width of 9.4cm) are put together for fulling. The washing temperature was 70 ℃ and the washing time was 12 minutes at a bath ratio of 1 to 20. The three-woven piece is felted until the size of the finished product reaches 30cm in length and 30cm in width, the vertical density of the finished product is 10K/cm, and the transverse density of the finished product is 6.67N/cm. When the tri-planar tissue piece is shrunk to the above size, the finished product of the twisted-pair tissue piece has the length of 20.1cm and the width of 9.4cm, the vertical density of the finished product is 2.89K/cm, and the transverse density of the finished product is 3.62N/cm.

The optimal matching pocket density in the three-plane length direction can be obtained according to the density, and the optimal matching pocket density is 30-turn stranded ropes corresponding to every 104-turn three-plane (104K/three-plane finished product vertical density multiplied by stranded rope finished product vertical density, namely the number of turns of stranded rope tissues under the same finished product length).

Tri-planar tissue and ribbing tissue collocation

Australian merino wool with the fiber fineness of 18.5 +/-0.3 mu m and the hair bundle length of more than 85mm is used as a raw material. 2/44NM wool is used to weave a three-flat fabric sheet with 8 pieces on the front surface and 2.5cm on the back surface, 10 meshes on the back surface and 2.3cm on a 12-needle flat knitting machine, and the size of the three-flat fabric sheet is 300 turns multiplied by 200 needles. A rib fabric piece was prepared, and a 1+1 rib fabric piece of 40 stitches x 100 turns was knitted with 2/44NM wool on a 7-stitch flat knitting machine with 4 yarns, 4 wales and 5cm, and the lower machine length was 32cm and the width was 8.9 cm.
