Embodiment 1

[0018] 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 nylon 66POY The yarn is installed on the adjacent spindle position, and passes through the raw yarn rack, the shredder, and the twist stopper in turn, without drafting and heating, and then the two yarns are plied by the network nozzle, and the composite yarn passes through the third roller, the yarn detector, Oiling rollers and winding to get nylon wool-like yarn. The operation method is as follows: select nylon 6POY23D / 7F raw yarn with a breaking elongation of 68% to enter the texturing machine for texturing, the draft ratio is 1.25, the temperature of the hot box is 162°C, and the false twister combination is 1-5-1. Then select nylon 66POY30D / 20F yarn with elongation at break of 150% to be compounded at...

Abstract

The invention belongs to the technical field of synthetic fibers, and specifically refers to a production method of wool-like nylon fibers. Nylon 6POY yarn is used as raw yarn, stretched and deformed, and nylon 66POY 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. The process of the invention is simple, and the wool-like nylon fiber produced has the characteristics of both wool yarn and nylon. The invention adopts a specific production process, and the wool-like yarn is superior to ordinary raw silk in terms of bulkiness, air permeability, softness, etc., which improves the yarn feel and loop uniformity, and at the same time avoids the production process due to special processes. Difficult to unwind. The woven fabric sample has a soft feel, and its wearing comfort is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of synthetic fibers, and specifically refers to a production method of 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. In order to improve the wearing comfort of fibers, nylon fabrics are currently developing in the direction of naturalization such as wool-like, silk-like, hemp-like, and suede-like, as well as high value-added functionalization and differentiation. [0003] At ...
