Background

Nowadays, people are pursuing healthy, comfortable and quiet life, and low lightness card is highly favored by the quiet, simple, soft and elegant color system. The well-known "seven second color theory" indicates that a commodity can reside in human consciousness in the form of color within seven seconds. Color is therefore the first sense to examine the quality index of textile fabrics. The current polyester/viscose blended low-lightness card has the risks of serious color change before and after high-temperature setting, dark gray color, low color light purity and high customer complaint rate.

At present, 70% of terylene/30% of viscose blended color matching raw materials of card color spinning comprise six types: 62.7% of light beige polyester fiber, 0.3% of golden yellow polyester fiber, 4.5% of ash polyester fiber, 2.5% of red and coffee polyester fiber, 7.5% of brown-green viscose fiber and 22.5% of camel-red viscose fiber. The color matching method has the defect of various colors, and three raw materials with the mixture ratio of less than 5 percent are added, so that the number of production procedures is increased, and the production efficiency is reduced. Moreover, the card colored spun yarn obtained based on the current color matching method has serious overall color change before and after high temperature, and is difficult to meet the requirements of customers.

Detailed Description

In order to make the technical scheme, the technical problems to be solved and the technical effects of the present invention more clearly apparent, the following technical scheme of the present invention is clearly and completely described with reference to the specific embodiments.

The first embodiment is as follows:

the embodiment provides a color matching method of a card color functional colored spun yarn, which comprises the following steps:

(1) selecting polyester fibers and viscose fibers according to the proportion of 7:3, referring to the attached drawing 1, wherein the polyester fibers comprise light beige polyester fibers with the proportion of 43% and coffee camel polyester fibers with the proportion of 27%, and the viscose fibers comprise light beige viscose fibers with the proportion of 21% and coffee brown viscose fibers with the proportion of 9%;

(2) the polyester fibers and viscose fibers selected according to the proportion are put together and sequentially pass through an SMBG012 type cotton mixer, an FB128 type cotton carding machine, an FA306A type drawing frame, an FA306A type roving frame and an FA306A type spinning frame to obtain the dyed yarns with the colors thereof. In this example, the card colored spun yarn was woven into a woven piece by a flat knitting machine in order to compare color changes more favorably.

In the embodiment, referring to fig. 1, the polyester fibers are light yellow polyester fibers with a lot number of BY001 and camel polyester fibers with a lot number of 20191116, which are produced BY huntington chemical fiber spinning limited company, and the specifications of the light beige polyester fibers and the camel polyester fibers are both 1.56dtex 38 mm. The viscose is light yellow viscose with the batch number of Y2012-38X and coffee camel viscose with the batch number of 210550, which are produced by Hebei Jixiong chemical fiber Limited liability company, and the specifications of the light beige viscose and the coffee brown viscose are both 1.44dtex 38 mm.

Referring to the attached drawings 2, 3 and 4, the woven piece woven by the card colored spun yarn is obtained in the embodiment, the woven piece is placed in a YT101 digital display high-temperature oven at 195 ℃ for 3min and then taken out, when the condition of constant temperature of 20 ℃ +/-2 and constant humidity of 64% +/-3 is reached, the colored light is compared with the colored light of the woven piece under a D65 standard light source, and the test of a color measuring electronic computer color matching instrument Datacolor800 can find that: the CMC total tolerance of the knitted piece is 0.54, the color saturation is-0.34, and the color light stability before and after high temperature reaches the qualified standard of 4-5 grade.

Based on the color matching method of the card color spun yarn blended by 70% of polyester/30% of viscose stated in the background art, referring to the attached drawing 6, according to the set proportion, 1.56dtex 38mm and batch number B002-31X light beige polyester fiber produced by the Hangzhou Benma chemical fiber spinning limited company, batch number B008-13X golden yellow polyester fiber, batch number E2008-18X soot polyester fiber, batch number N2006-18X red coffee polyester fiber, batch number 201930 brown green viscose fiber produced by the Wuhanchen chemical fiber spinning limited company and batch number dye printing and dyeing of 1.44dtex 38mm and Wuhan Xiaxin limited company, and batch number 202463 camel red viscose fiber are selected. Referring to the attached drawings 7, 8 and 9, the card color spun yarn obtained by the six raw materials is placed in a YT101 digital display high-temperature oven at 195 ℃ for 3min and then taken out, and when the condition that the temperature is constant at 20 ℃ +/-2 and the humidity is constant at 64% +/-3, the card color spun yarn is compared with the card color spun yarn under a D65 standard light source in color and light, and the color and light contrast result is found after the test of a color measuring electronic computer color matching instrument Datacolor 800: compared with the color difference before high temperature of 2-3 grades after high temperature, the color difference is reddish-2.12, deep-3.43, under-saturated-0.95 and the total tolerance of CMC is 4.11 (qualified less than 0.8), the original color card has serious color change and is transformed into a camel-red system.

Compared with the existing color matching method, the total tolerance of the CMC is reduced from 4.11 to 0.54, which is improved by 86%; the saturation is reduced from-0.95 to-0.34, the color light purity is improved by 64 percent, the high-temperature color light stability is improved from 2-3 level to 4-5 level, the national standard is reached, and the types of raw materials are reduced from 6 to 4; the small proportion is reduced from 3 to 0; the requirements of color light of customers can be met, production burden can be reduced, and production efficiency is improved.

Example two:

based on the color matching method of the first embodiment, when the proportion of the light beige polyester fibers is larger than that of the coffee camel polyester fibers, the proportion of the light beige viscose fibers is not smaller than that of the coffee brown viscose fibers.

The proportion range of the camel coffee polyester fiber is 0-60%; the proportion range of the coffee palm viscose fiber is 0-20%.

Referring to the attached drawing 5, in the embodiment, polyester fibers and viscose fibers are selected according to the ratio of 7:3, and by changing the ratio of four raw materials, namely light beige dacron, coffee camel dacron, light beige viscose and coffee brown viscose, card color spun yarns with different light and shade and multiple color phase changes can be obtained, so that a card color database is established, a color card is formulated, the establishment of the card color database is realized, the corresponding color matching of the colors of any card color system is obtained, the color spun yarns can be produced by only selecting the corresponding colors of customers in the production process, color matching is not needed again, and the production process is simple, rapid and labor and material resources are saved.

It is necessary to supplement that the card color spun yarn can be woven into 5cm by 5cm woven pieces, that is, the woven pieces can be selected by customers according to the database and the color card.

In conclusion, the color matching method of the card color functional colored spun yarn can improve the production efficiency, and the obtained card color spun yarn has the characteristics of high color purity and high color stability.
