Description
Technical field
The present invention relates to textile industry, specifically a kind of conductive fiber that utilizes original liquid coloring.
Background technology
Polyester fiber, pet fiber particularly, has excellent performance at aspects such as DIMENSIONAL STABILITY, heat resistance and resistances to chemical reagents, and be widely used in dress material and industrial circle, but because its hygroscopicity is poor, the friction back easily produces static (bringing electrostatic hazard, as spark discharge and dust suction) and is subjected to certain restriction.Other textile fabrics such as polyamide fibre, wool etc. also easily produce static in addition.
The effective measures that solve electrostatic hazard in the past are to add the electrically conductive composite fibre that a spot of polymer that is dispersed with conductive carbon black constitutes in textile fabrics, thereby reach permanently antistatic.This method is mainly used in carpet, the dust-free sterile clothes of electronics pharmaceuticals industry, the antistatic protective clothing of petroleum chemical industry and the occasion that some are relatively more responsive to static.But because conductive carbon black is a black, also present certain secret note, influenced the use field and cause conductive fiber to be black, textile fabrics; The white conductive fiber that adopts light color or white metal oxide conducting powder is also arranged in addition, but because its host material is terylene, nylon etc., be not quite similar, thereby still have color distortion during dyeing with the base material of weaving face fabric.
Summary of the invention
The objective of the invention is to seek a kind of original liquid coloring composite conducting fiber, so that make the color of conductive fiber consistent with the color and luster of made goods.
At the problems referred to above, the present invention will be how consistent with the color and luster of made goods research topic the color of conductive fiber, find through studying intensively the back, adopt core-skin composite spinning silk method, after adding colouring agent, photomask agent and pore former in the cortex component at conductive fiber, just can be made into well behaved coloured conductive fiber, and can be according to the color of colouring agent, the color that content changes conductive fiber, make the scope of application of conductive fiber wider, and COLOR FASTNESS further improve.
