Antistatic composite fiber precursor, antistatic processed yarn prepared therefrom, and manufacturing method therefor

Abstract

The invention relates to an antistatic composite fiber precursor, an antistatic textured yarn prepared through using it, and a method for preparing the antistatic textured yarn through using the antistatic composite fiber precursor. The antistatic composite fiber precursor is prepared through conjugate spinning of a conductive composite polymer base material including 10-30wt% of conductive carbon block, and a fiber polymer base material, and the volume proportion of the conducive composite polymer base material in the antistatic composite fiber precursor is 20-60%. The addition of the conductive carbon black and the cooperation of the support and protection mechanisms of the fiber polymer base material make the antistatic composite fiber precursor have a difficult fracture processing strength and a good and long-term effective conductivity, and can be processed to form the antistatic textured yarn having a curling appearance and a fluffy feeling, so it is helpful for the diversified application of the antistatic fiber, and the practical values of the antistatic fiber are improved.

Description

technical field [0001] The present invention relates to an antistatic fiber and its manufacturing method, in particular to an antistatic composite fiber precursor which is suitable for processing and has a permanent antistatic effect, an antistatic processed yarn made of it and a manufacturing method used therefor . Background technique [0002] Synthetic fiber polymer materials are common textile materials and are widely used in clothing. Since synthetic fiber polymer materials are mostly insulating materials, when worn on the human body, they are prone to static electricity due to friction during human activities. The accumulated charge will cause discharge, attraction, etc. The light ones will cause discomfort to the wearing human body, and the severe ones will cause damage to the precision components that the human body touches (such as breakdown of electronic components), and even cause gas explosions and fires (such as , to ignite fuel vapor). Therefore, for clothing...

Problems solved by technology

Therefore, if the textile is used in a dry environment or after repeated washing, its effect will decrease rapidly, resulting in the antistatic effect obtained by this surface treatment method cannot be maintained for a long time, and it cannot be applied to clothing that generally needs to be washed frequently , but has the disadvantages of poor antistatic durability and limited application range

[0005] The second antistatic processing method is to add a conductive base material to the synthetic fiber polymer material. If the added conductive base material is a surfactant-based antistatic agent, the surfactant will disappear after the melt spinning process. It spreads to the surface of the fiber to form a semi-permanent antistatic fabric, which also has the problems of not being durable and not being able to wash frequently

However, the fibers obtained by this processing method cannot be processed to show bulkiness or increase crimp due to the problem of strength. Due to the inability of the conductive fiber to exhibit characteristics such as fluffy feeling or curling, it cannot be used to increase the diversity of textiles and provide better hand feeling, and has the problem that it is not easy to be applied to general clothing and the application range is limited.
