Embodiment

[0031] The present invention includes raw material processing, drying, POY silk manufacturing, DTY silk manufacturing, network processing and grading packaging, and the specific steps are as follows:

[0032] (a) Raw material treatment: prepare the raw materials for preparing nylon yarn, including nylon 66, antioxidants, catalysts, dispersants, antibacterial agents and other auxiliaries, nylon 66, antioxidants, catalysts, dispersants, antibacterial agents and other auxiliaries The weight components of the agent are nylon 6658%, antioxidant 4%, catalyst 15%, dispersant 12%, antibacterial agent 10.5%, and other additives 0.5%. Antioxidant selects sulfite DLTP, catalyst selects sodium fluoride and sodium silicate, the ratio of sodium fluoride and sodium silicate is 2:1, dispersant selects polycaprolactone, antibacterial agent selects silver-loaded zeolite, and other additives Choose antistatic agent fatty alcohol polyoxyethylene ether AE and easy dyeing agent polystyrene. The ra...

Abstract

The invention discloses a polyamide yarn production technology. The polyamide yarn production technology comprises the following steps of treating raw materials, drying, preparing POY yarns, preparing DTY yarns, carrying out net treatment, classifying and packaging. According to the technology, an anti-oxidant, an anti-static agent and an antibacterial agent are added in the raw materials, so that the performances of a chinlon 66 finished product is improved, and the produced chinlon yarns have the anti-bacterial and anti-static effects; a easily dyeable agent is also added in the raw materials, so that the dyeing performance of the finished product is improved; by utilizing the production processes of the POY and DTY net yarns, yarn floating is prevented, and net breaking is low, so that the fluffy property and the good elasticity of the chinlon yarns are kept, the chinlon yarns also have the cycle property and net points, the stability is good, the compactness of the long yarns is improved, and the handfeel and the comfort of the finished product are effectively improved.

Description

【Technical field】 [0001] The invention relates to the technical field of yarn processing, in particular to the technical field of the production process of nylon filaments. 【Background technique】 [0002] Nylon, the scientific name of polyamide fiber, is the collective name of polyamide fibers produced in China, and is called nylon internationally. High strength, wear resistance, good resilience, can be pure and blended for all kinds of clothing and knitwear. The main varieties are nylon 6 and nylon 66, and their physical properties are similar. Nylon filament is a fiber made of polyamide, which is divided into nylon filament and short filament. Nylon filament can be made into elastic yarn, and short yarn can be blended with cotton and acrylic to improve its strength and elasticity. In addition to the application in clothing and accessories, it is also widely used in industries such as cords, transmission belts, hoses, ropes, fishing nets, etc. Fiber fine denier and func...
