Embodiment 1

[0015] A production process of nylon wool-like yarn, the nylon 6POY yarn is sequentially passed through the original silk frame, the first roller, the shredder, the twist stopper, the hot box, the cooling plate, the false twister, and the second roller; at the same time, the other The standard nylon 6POY yarn is installed on the adjacent spindle position, and passes through the raw silk frame, the shredder, and the twist stopper in sequence, without drafting and heating, and then the two yarns are plied by the network nozzle, and the composite yarn passes through the third roller, Wire feeler, oiling roller, winding, and nylon wool-like yarn can be obtained. The operation method is as follows: the yarn is selected from the nylon 6POY60D / 48F raw silk with a breaking elongation of 66% and fed into the texturing machine for texturing, the draft ratio is 1.07, the temperature of the hot box is 200 ° C, the false twister combination is 1-7-1, The friction disc is made of PU, the im...

Embodiment 2

[0017] Nylon 6POY85D / 48F raw silk with a breaking elongation of 65% is used to feed the texturing machine for texturing, the draft ratio is 1.1, the temperature of the hot box is 210°C, the false twister combination is 1-7-1, the export disc is a ceramic disc, and the friction The disc material is PU, the ratio of untwisting tension to twisting tension is 0.35, and nylon 6POY36D / 36F yarn with a breaking elongation of 65% is selected to be compounded at the network spraying point, and the winding speed is 480m / min. In this way, the strength is 4.1cn / dtex, and the 120D / 84F nylon 6-like linen-like wool-like yarn whose elongation at break is 26%.

Embodiment 3

[0019] Nylon 6POY60D / 24F raw yarn with a breaking elongation of 63% is used to feed the texturing machine for texturing, the draft ratio is 1.08, the temperature of the hot box is 205°C, the false twister combination is 1-7-1, the export disc is a ceramic disc, and the friction The disc material is PU, the ratio of untwisting tension to twisting tension is 0.45, and nylon 6POY48D / 12F yarn with elongation at break of 69% is selected to be compounded at the network nozzle, and the winding speed is 400m / min. In this way, the strength is 3.8cn / dtex, and the 110D / 36F nylon 6 linen-like wool-like yarn whose elongation at break is 26%.

[0020] The invention adopts a specific production process to make the cloth surface woven from nylon yarn close to the fabric style of hemp yarn and wool yarn in terms of appearance and feel. It not only has the high elasticity and wear resistance of nylon, but also has a certain three-dimensional effect and hemp The cloth surface produced by this ya...

Abstract

The invention belongs to the technical field of synthetic fibers, and specifically refers to a production method of linen-like wool-like nylon fibers. Nylon 6POY yarn is used as raw yarn, stretched and deformed, and another specification of nylon 6POY yarn that has not been stretched and heated is plied at the network nozzle to form a plied yarn until it is wound into shape. Using a specific production process, the fabric surface made of nylon yarn is close to the fabric style of hemp yarn and wool, and also has the high elasticity and wear resistance of nylon. The composite effect of the yarn is good, and the normal unwinding of the yarn is guaranteed. The produced fiber has a certain three-dimensional and hemp feeling, and has a lace-like hollow effect and a special pattern on the fabric sample produced by it. Wearing comfort has been greatly improved.

Description

technical field [0001] The invention belongs to the technical field of synthetic fibers, and specifically refers to a production method of linen-like wool-like nylon fibers. Background technique [0002] With people's continuous requirements for the hand feel, light feeling and comfort of clothing and other textiles, the performance requirements for nylon yarn are also continuously increasing. Compared with other synthetic fibers, nylon 6 has excellent abrasion resistance, elasticity, fatigue resistance, moisture absorption, and smooth hand feeling. It can be directly dyed with acid dyes and other dyes, and is resistant to alkali and other chemical agents. The finished garment is bulky and still has an uncomfortable waxy feel. Natural hemp fabric has the characteristics of fast water absorption and drainage, ventilation and breathability, cool and comfortable, and unique luster of hemp. However, hemp fiber has poor elasticity, is not resistant to wrinkling, feels rough and...
