Background

Hemp fiber is one of the earliest utilized textile fibers in human history, and has been in thousands of years history to date. Whether flax, ramie, jute, hemp, apocynum and the like are easy to generate a large amount of noil in the textile production process, the related literature reports that one ton of hemp long fibers are produced and about 1.2-1.4 tons of noil are generated simultaneously; about 40% -60% of noil is also generated in the spinning production process of ramie; the ratio of flax and noil also reaches the range of 1: 1. After various hemp fibers are long-spun and combed, a large amount of short fibers and a few long fibers with net leakage are left. In the case of hemp noil, the percentage of long fibers of 65MM or more is about 15%, and the percentage of short fibers of 16MM or less is about 30%. The hemp noil has short length, more impurities and poor uniformity, belongs to leftovers of a spinning mill, and has low utilization rate and utilization value of other noils except for a part of noils which are processed and blended by a blending process.

At present, there are many reports on the comprehensive utilization of hemp fiber resources, and the researches mainly focus on fiber degumming, spinning, paper making, biopharmaceuticals (cannabinol, tetrahydrocannabinol and CBD extraction), and the like. The research on the utilization of the noil mainly focuses on the aspects of hemp viscose, cotton and hemp blending and the like. While the noil is not reported in the aspect of filling the wadding of the cotton quilt of the home textile cotton clothes for manufacturing the textile clothes. The residual noil loses the value of long-spinning and short-spinning blending in the textile industry, but the physical properties of the hemp still exist, and the excellent characteristics of mildew resistance, bacteriostasis, static resistance, ultraviolet resistance, excellent moisture absorption and air permeability, certain water content locking and the like still exist in the noil. The reasonable utilization of the noil is particularly important for fully utilizing the physical properties of hemp raw material resources, reducing the enterprise cost and improving the market competitiveness of hemp textiles.

At present, the padding flocculus used for the home textile of clothes in the world is roughly divided into the following types. Natural fibers: such as cotton, silk, hemp; animal villi: such as down, wool, camel hair; chemical hot-melting to synthesize flocculus: such as, for example, spray bonded, non-bonded, spun bonded, eleven-hole, and the like. However, these filled batts have drawbacks for consumers to use and are not desirable. Besides its advantages, natural fibre wadding (cotton, etc.) is poor in air permeability, easy to harden, easy to mildew after being wetted, heavy and poor in elasticity, easy to wrinkle after being washed, and heavy when being covered on the body, and these defects are never corrected. Animal fluff flocculus, as wool flocculus, has no antibacterial and insect-proof performance, can generate peculiar smell, yellowing and other phenomena after being placed for a long time, can also generate insect eggs in humid climate, can shrink, fall hair and pilling when in use, and is expensive. Chemical synthetic flocculus, such as spray-bonded cotton, non-bonded cotton and spinning cotton flocculus, has poor hygroscopicity and weak water absorption, and is easy to absorb dust; secondly, the air permeability is poor, the air permeability is difficult, and static electricity is easy to generate; thirdly, the melt resistance is poor, and the fabric can have holes after passing through the spark. The combination of noil and synthetic fiber (PET) exactly complements the advantages of two different fiber attributes and is novel in the textile filling flocculus. The noil fiber is added with the lyocell polyester staple fiber and the fine denier silicon-containing polyester staple fiber, and the self defects of the chemically synthesized flocculus are overcome by utilizing the superior characteristics of the hemp fiber, such as mildew resistance, bacteriostasis, static resistance, high temperature resistance, ultraviolet resistance, quick moisture absorption and dispersion, good air permeability and the like. And because the synthetic fiber (PET) has the advantages of high strength, good heat resistance, low hygroscopicity, strong elasticity (the elasticity is 2-3 times of that of nylon), difficult crease, quick recovery and the like, the defect of the hemp fiber is also made up. The noil and the synthetic fiber (PET) are heated and bonded by using the white polyester staple fiber (low melting point) fiber according to the burning point values of the noil and the synthetic fiber, so that the filling flocculus has the characteristics of low carbon, environmental protection and good heat-moisture qualitative performance. In the actual process operation, the conventional method of one carding machine is abandoned, production equipment is designed, combined and optimized, three carding machines are used for carding and forming a net, a middle machine is used for producing synthetic fibers, two edge machines are used for producing hemp fibers and low-melting-point fibers, and the mixed fibers are mixed and paved by three lapping machines. The padding flocculus is divided into three layers: the upper layer and the lower layer are bonded by hemp fibers and low-melting-point fibers, so that the characteristics of the hemp, such as mildew resistance, bacteriostasis, static resistance, quick moisture absorption and dispersion, air permeability and body refreshing, are fully exerted. The middle layer is made of synthetic fiber (PET) polyester staple fiber and fine denier silicon-containing polyester staple fiber to play the advantages of the synthetic fiber (PET), so that the filling flocculus has better elasticity, is more flexible, does not stick hair and has higher strength, and supports the upper and lower layers of hemp net fiber. The novel production process and equipment enable the noil and synthetic fiber (PET) filled flocculus to have perfect combination and new breakthrough. The finished product of the wadding sheet has the characteristics of stiffness without hardness, lightness without floating, warmness without stuffiness, mildew resistance and bacteriostasis, moisture absorption and ventilation, super softness and refreshing, good recovery property after being pressed and wrinkled, good shape retention, super-strong elasticity, smoothness and like fluff. It is not comparable to the single fiber filled flocculus.
