Problems solved by technology

[0004] Although the fine denier fibers obtained in the above-mentioned patents are light and thin, have good softness and good drape aesthetics, their disadvantages are: the strength of the obtained fabrics is reduced due to the thinner monofilaments, and the fabrics are particularly easy to be hooked or scratched by hooks when they are scraped by hooks. Fractures, resulting in fabric surface flaws or damage

preparation example Construction

[0030] A preparation method of tightly twisted anti-snag fiber, comprising the following steps:

[0031] 1) Preparation of POY filaments: POY filaments were prepared at a spinning speed of 3800-4000 m / min.

[0032] The material of the POY yarn is polyester or nylon 6. The specification of the polyester POY fiber is 30-475dtex / 3-288f; the specification of the nylon 6 POY yarn is 15-150dtex / 3-96f.

[0033] 2) The obtained POY yarn is wound on a rotatable winding disk, and the POY filament is transported to the false twist texturing machine while controlling the rotation of the winding disk; wherein the steering of the winding disk is related to the twisting of the POY silk in the false twist texturing machine. to the opposite. The rotating speed of the reel is 100-500 revolutions per 1 meter of POY yarn conveyed, so that the twist of the POY yarn when it reaches the false twist texturing machine is 100-500 twists / meter.

[0034] 3) False-twisting and deforming the POY yarn by...

Embodiment 1

[0041] A preparation method of tightly twisted anti-snag fiber, the PA6POY yarn of 90dtex / 48f is produced at a spinning speed of 3900m / min, and the raw silk frame is transformed on a false twist texturing machine (for details, see figure 1), so that the wire roll can be driven by the motor to rotate, and the motor can be adjusted by the frequency converter, so that the POY monofilament has a twist of 100 twists / m before entering the false twist deformation processing area, and then undergoes false twist deformation, and the production speed 300m / min, draw ratio 1.30, a hot box 180°C, D / Y 1.8, 70dtex / 48f PA6 tight twist anti-snag fiber DTY was prepared.

Embodiment 2

[0043] A kind of preparation method of tight-twisting anti-snag damage fiber, the PET POY silk of 50dtex / 24f is made with the spinning speed of 3800m / min, transforms the raw silk frame on the false twist texturing machine (reformation details see figure 1 ), so that the wire roll can be driven by the motor to rotate, and the motor can be adjusted by the frequency converter, so that the POY monofilament has a twist of 300 twists / m before entering the false twist deformation processing area, and then undergoes false twist deformation, and the production speed 500m / min, draw ratio 1.72, first hot box 200°C, second hot box 180°C, D / Y 1.90, 30dtex / 72f PET tight twist anti-snag fiber DTY was prepared.

Abstract

The invention relates to a spinning technology and discloses a preparation method of tightly twisted fiber capable of preventing hook damage. The method comprises the steps of 1, preparing POYs, wherein the POYs are prepared at a spinning speed of 3,800-4,000 m / min; 2, winding the obtained POYs on a rotatable yarn winding disc and conveying the POYs to a false twist texturing machine during control over the rotation of the yarn winding disc, wherein the turning direction of the yarn winding disc is opposite to the twisting direction of the POYs in the false twisting texturing machine; 3, performing false twist texturing on the POYs through the false twist texturing machine to obtain a finished product. According to the method, the fiber twist is increased through rotation of raw yarns before false twist texturing, the residual torque of the fiber is optimized and improved in cooperation with a process, the fiber has high twist, and monofilaments are not bonded with one another at the same time through proper high-temperature shaping, so that the shaping performance is great. In addition, the obtained yarns have ideal fluffiness and are high in strength and not stiff, and a great anti-hook and anti-scrape effect is achieved on the monofilaments.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a preparation method of tightly twisted anti-snag fibers. Background technique [0002] With the development of people's pursuit of wearing comfort and aesthetics of clothing fabrics, the fine and porous fibers have become an important development trend. On the one hand, the thickness of clothing fabrics continues to decrease, the fabric is light, and the moisture absorption and breathability and aesthetics increase. On the other hand, in order to improve the softness of the fabric, the monofilaments are getting thinner and the number of monofilaments is relatively increasing. With the continuous development of fiber fine denier, the lightness, softness and drape aesthetics of fabrics are constantly increasing. [0003] The Chinese invention patent with publication number CN103306013A discloses an ultra-fine fiber ultra-thin fabric, the ultra-fine fiber ultra-thin fabric is mad...
