Q: What is functional nylon yarn?

A: TIn the past 10 years, with the structural adjustment of the world fiber industry and the transfer to China, the research and development and application of functional nylon has accelerated and improved greatly. Great progress has been made in the research and development and application of modified additives, high-performance slices, functional masterbatch and functional fibers.

The so-called functional nylon is a PA fiber with some special functions developed by modifying ordinary PA or using biomass PA. For example, health care PA for clothing, wear comfort PA, flame retardant PA for decoration, enhancement PA for industry, protection PA, improve the processing performance of spinning, weaving, dyeing and other process links, and green and environmental protection PA. The research and development of functional nylon abroad began about the 1970s, the United States, Japan, Europe and other countries and regions are more advanced, domestic research and development started later.

The ASP(Advanced Spinning Performance)PA6 modifier system and Nylostab S-EED, a high-performance additive for PA6, developed by ZIMMER in cooperation with Clarian, have been applied to ZIMMER's PA6 polymerization plants in Lipeng, Taiwan and Liheng, Fujian with remarkable results. In addition, Invista of the United States and Germany's BASF cooperation to develop a variety of additive combination.

Chinese enterprises have some innovations in this respect. Jiangsu Junma Company made use of activated nano montmorillonite (OMMT), controlled the reaction temperature, pressure, time and other parameters of the two-stage polymerator by in-situ intercalation polymerization principle, realized the continuous and stable industrial preparation of peel type PA6/ nano OMMT composite material (section), and its fracture strength was 102.15MPa, 12% higher than that of pure PA6. Suitable for making high performance cord. Kaisai Bio-Industry Co., Ltd. uses bioyl glutarenediamine and dibasic acid to copolymerize into a new green resin, which is used in the production of green polyamide, engineering plastics and films. It is a bio-based fiber, green and environmental protection. At the same time, domestic colleges and universities have also developed modified varieties. For example, Tianjin Polytechnic University developed PA6 slices with enhanced hygroscopicity and staining by adding the second and trimonomer to increase the content of amine groups on the main chain of PA6 and reduce the regularity and crystallinity of the molecular structure.

In addition to the addition of functional additives from the polymerization system, the more flexible and more commonly used technology is to blend them with PA slices and reprocess them into master granules, which are added through the feeding machine from the feed port of the screw spinning machine to produce the corresponding functional nylon filament. Functional PA6 masterbatch has been researched and developed in many ways, and several major ones are introduced here.

The research and development of silver PA6 antibacterial masterbatch is quite extensive, some are trial-produced in the laboratory, and some have been large-scale industrial supply market. The special PA6 produced by Shanghai Huangu New Material Technology Co., Ltd. and Huading Nylon Co., Ltd. has long-lasting, efficient and broad-spectrum antibacterial effect.

PA can also be added flame retardant masterbatch, using high-performance PA slice and flame retardant agent mixed in screw extruder, to produce various types of PA flame retardant masterbatch, for the production of flame retardant nylon or engineering plastics.
