Conductive fibre

Abstract

A conductive fiber is characterized in that the fiber is composed of conductive masterbatch and fiber grade resin sections, wherein, the weight percentage of conductive masterbatch in the fiber is from 20% to 30%. The production method includes (1) coupling agent, carrier resin and dispersant are added to dried conductive powder for mixing and then the mixture is melted and extruded, cooled and granulated through a twinscrew so as to prepare conductive masterbatch; (2) fiber grade PP resin sections are added in the conductive masterbatch and spun by adopting a hot-melt extrusion spinning method. The invention has the advantages that (1) under the precondition of no change of the physical and chemical properties of the polypropylene fiber, the invention solves the problem of the permanent conductivity of polypropylene fiber basically and effectively to achieve an antistatic effect without impacting other fine properties of polypropylene fiber; (2) the tensility, strength and color fastness of the fiber can not be affected and the fiber is suitable for making various clothing and costume; (3) the invention has mature technique and low production cost, thus being able to be applied and popularized.

Description

technical field [0001] The invention relates to a functional fiber in the textile field and a manufacturing method thereof, in particular to a conductive fiber and a manufacturing method thereof. Background technique [0002] The common problems of chemical fibers are poor hygroscopicity, good insulation and serious static electricity. Static electricity in chemical fiber clothing will continue to accumulate during use, which is very unfavorable to human health, and it is easy to cause danger in special places (such as gas stations). Therefore, how to make chemical fiber conductive is an important topic in the field of chemical fiber research. At present, there are roughly three types of methods at home and abroad to make chemical fibers have antistatic or conductive functions: one is to treat the surface of chemical fibers to make them conductive, such as coating or electroplating a layer of conductive material on the surface or making them conductive by boiling, dyeing an...

Problems solved by technology

At present, the third method is commonly used to add conductive carbon black to chemical fiber, which can achieve good conductive effect, but it also has its disadvantages or imperfections, mainly in: first, it makes the fiber black, which is not conducive to dyeing, It has a great impact on the production of clothing; second, it will lose electrical conductivity due to excessive storage time or high temperature during spinning; third, it has a greater impact on the physical and chemical properties of chemical fibers, which is reflected in the reduction of fiber stretchability , strength and color fastness

To sum up, the method of adding conductive particles to chemical fibers by melt spinning method has become the main development direction of conductive fibers, but what kind of conductive particles should be used to ensure the permanent conductivity of fibers without damaging the fibers? The physical and chemical properties of the fiber, which do not affect the application of the fiber in clothing, are still a problem
