Process for producing antistatic polyamide 6 (PA6) bulk yarns through one-step process

Abstract

The invention discloses a process for producing antistatic polyamide 6 (PA6) bulk yarns through a one-step process. According to the technology, the polyamide 6 (PA6) bulk yarn fibers produced by the one-step production process have excellent electrical conductivity, and the manufactured carpet is rubbed to generate static electricity so as to be timely conducted out under severe pedaling, so the carpet has excellent antistatic properties. According to the technology, the polyamide 6 conductive fibers refer to 10-20-denier polyamide 6 carbon black composite fibers, and the composite fiber refers to a core-sheath composite fiber which takes the polyethylene dispersed with carbon black as the core and takes polyamide 6 as the core, is a conductive fiber with physical and chemical performances of polyamide 6 fibers, and can finish the drafting and bulking deformation process with polyamide 6 (PA6) fibers in high-speed production process.

Description

technical field [0001] The invention relates to a one-step production process for antistatic nylon 6 (PA6) bulked yarn. Background technique [0002] Nylon 6 (PA6) fiber has become the raw material of choice for high-end carpets in recent years due to its good elastic recovery, wear resistance and low manufacturing cost. However, during the long-term use of nylon 6 fiber, people found that under high friction conditions The generation of static electricity will cause safety hazards to the use environment, especially in crowded places such as commercial shopping malls, hotels, guesthouses and other places in the dry season, it is easy to generate static electricity, and after a high concentration of static electricity, high voltage will be generated to a certain extent, and it will happen in severe cases. casualties or fire accidents. Therefore, the country has gradually strengthened the quality control of carpet products, and successively issued national standards for vario...

Problems solved by technology

At present, in the carpet manufacturing industry, in order to meet the antistatic requirements of the national standard, there are two technical routes. One is to add an antistatic agent spraying process to the carpet production. This technical solution not only increases the production cost, but also increases the production process environment. Pollution, the second route uses antistatic nylon fibers, but in the development of antistatic nylon fibers, the ratio of nylon 6 and conductive fiber components used can only achieve effective antistatic effects when the ratio is 10-50:1. This technology In the scheme, due to the high content of conductive fibers, the elastic recovery performance and wear resistance of nylon 6 bulked yarn are reduced, and the lodging resistance and wear resistance of the carpet products made can not meet the relevant national standards. Therefore, most Carpet producers still choose the first antistatic agent spraying technical scheme. After the technical invention has selected the nylon 6-carbon black composite fiber with excellent electrical conductivity, after the ratio of the conductive fiber is reduced to 50-120:1, the The developed nylon 6 antistatic bulked yarn completely retains the good elastic recovery and wear resistance of nylon 66, and can replace the conventional process of carpet products with an antistatic treatment process with good antistatic performance advantages
