Problems solved by technology

Due to the high plasticity of polyester, it can be used in a wider range and the price is much lower than before. However, in the process of using polyester yarn, the yarn strength is low, the fabric is easy to deform after washing, the resilience is poor, and the handle is rough. The problem is that the fabric is not easy to degrade and cannot be recycled, causing environmental pollution

Embodiment 1

[0020] A kind of industrial yarn production process of renewable fiber, comprising the following steps:

[0021] 1) Wool selection: Merino wool with a fineness of 18.4mic is used as raw material, no wool treatment is required, and renewable polyester fibers are selected with a fineness of 2.2dtex and a length of 88mm;

[0022] 2) Mixing: adjust the blending ratio of wool and polyester fiber to 1:1 for mixing;

[0023] 3) combing: the weeds and hair particles in the sliver are combed out to further straighten the fiber, the combing weight is 20g / m, the tension between rollers is 1.02, and the carding speed is 150 nips / min;

[0024] 4) needle comb;

[0025] 5) Roving;

[0026] 6) Spinning: adopt the ring spinning method, control the spinning speed at 8000rpm, control the pressure of the spinning cradle at 3.0, and twist the roving slivers into semi-finished yarns through distraction;

[0027] 7) Winding.

[0028] In the step 6), the controlled temperature is 22° C. and the h...

Abstract

The invention provides an industrial yarn production process of renewable fibers, and relates to the technical field of composite functional yarns. The industrial yarn production process of the renewable fibers comprises the steps of raw material selection, twisting, heat setting treatment, cheese manufacturing and winding and folding. Specifically, cotton fibers and independently researched and developed moisture-absorbing and sweat-releasing fibers and moisture-absorbing and antibacterial fibers are selected as raw materials, have good moisture-absorbing, sweat-releasing and ventilation performance, are good in elasticity, antibacterial performance and strength, keep the moisture-absorbing and sweat-releasing performance of the fiber raw materials after twisting and heat setting treatment, further improve the elasticity, and are wound and folded to obtain the composite yarn. After being processed into a textile, the textile has good bacteriostatic and antibacterial properties, moisture absorption and sweat releasing properties and elasticity, and the production process is suitable for large-scale industrial application.

Description

technical field [0001] The invention relates to the field of spinning, in particular to an industrial yarn production process of renewable fibers. Background technique [0002] There are more and more polyester-wool blended yarns on the market, and their functionality varies with the proportion and type of polyester. Due to the high plasticity of polyester, it can be used in a wider range and the price is much lower than before. However, in the process of using polyester yarn, the yarn strength is low, the fabric is easy to deform after washing, the resilience is poor, and the handle is rough. The problem is that the fabric is not easy to degrade and cannot be recycled, causing environmental pollution. In order to meet the needs of consumers and improve the above problems, we have developed a blended yarn of renewable polyester and wool, which blends renewable polyester and wool. By increasing the proportion of renewable polyester, the cost of raw materials is reduced while...
