Problems solved by technology

However, because the fabric uses an alkaline solution to treat the polyester / polyamide composite fiber, the weight loss rate of the fabric is relatively large, and the degree of disintegration is not high, only higher than 75%.

Abstract

The present invention relates to a split-separation method of composite fibre in the dyeing and finishing process of polyester / polyamide composite fibre fabric and the polyester / polyamide composite superfine fibre fabric. In the above mentioned method a weak acid solution whose pH value is 5-6.5 is adopted to treat fabric so as to make polyester and polyamide automatically split and separate, and its split-separation degree is high. Said method does not damage fabric, and the mechanical property, comfortability and colourability of fabric can be improved.

Description

technical field [0001] The present invention relates to a dyeing and finishing method of polyester / polyamide composite fiber fabric and superfine fiber fabric obtained by the method, more specifically, relates to a polyester / polyamide composite fiber fabric in the dyeing and finishing process of composite fiber The splitting method and the polyester / polyamide composite superfine fiber fabric obtained by the method. Background technique [0002] At present, the research and development of superfine fibers is progressing rapidly, and numerous "new synthetic fiber" fabrics based on superfine fibers have been produced. The comprehensive advantages of superfine fibers are incomparable to ordinary fibers, and have high added value. Its extremely fine monofilament size, large specific surface area and special-shaped fiber cross-section endow the fabric with soft feel, natural luster and good moisture absorption and moisture permeability. [0003] Composite microfiber is an import...
