Problems solved by technology

Some dyes are combined with fibers for dyeing, and 1 / 4 to 1 / 3 of the dyes are adsorbed on the surface of the fibers, and often enter the sewage when the fabric is cleaned, increasing COD emissions and causing environmental pollution

Embodiment 1

[0020] (1) Production of superfine fiber filaments:

[0021] Component A is polyethylene terephthalate, with a mass percentage of 80% and a crystallinity of 85%; the colored masterbatch is component A of carbon powder with an amount of 15% (hereinafter the same);

[0022] Component B is a polymer of terephthalic acid and ethylene glycol, with a mass percentage of 20% and a crystallinity of 30%.

[0023] The fiber comprises a central colored polymer A and polymer B surrounding polymer A. Such as figure 1 As shown, there are 21 colored A (fineness 0.2dtex) in the fiber surrounded by B, which shows that the number of colored islands in the fiber of the present invention is 21. In actual production, the number of islands according to the fiber of the present invention can be in Between 20 and 30, the shape can be round, five-pointed star ★, trefoil Y and other shapes.

Embodiment 2

[0028] Component A and component B raw materials are as follows:

[0029] Component A is polyethylene terephthalate, with a mass percentage of 70% and a crystallinity of 90%; the colored masterbatch is component A of carbon powder with an amount of 10%;

[0030] Component B is a polymer of terephthalic acid and ethylene glycol, with a mass percentage of 30% and a crystallinity of 30%.

[0031] The preparation method is the same as in Example 1. The main indicators of the non-dyed suede fabric finished product are as follows:

[0032] Rubbing color fastness: dry grinding 3.5, wet grinding 3.5; washing color fastness: water immersion 3.5, staining 3.5; soaping color fastness: water 3.5, staining 3.5.

Abstract

The invention relates to a superfine fiber filament. A single fiber 1F comprises 20-30 colored filament-shaped components A ( the fineness of a single filament is about 0.2 d tex) and components B which surround and fill the peripheries and gaps of the components A; the mass percentage content of the components A ranges from 75% to 95%; the mass percentage content of the components B ranges from 5% to 25%; the crystallinity of the components A ranges from 60% to 90%; the crystallinity of the components B ranges from 5% to 40%. The superfine fiber filament provided by the invention has the following benefits: dye is not required, so that dyeing wastewater is not generated and the environment is not subject to the dyeing pollution; the quality of the chamois leather fabric is greatly improved.

Description

(1) Technical field [0001] The invention relates to a superfine fiber filament and a method for making non-dyed suede fabric by using the superfine fiber filament. (2) Background technology [0002] Suede fabrics are now more and more widely used in people's lives, mainly in the fields of clothing, sofas, shoes, hats, and bags. Suede is mainly made of sea-island microfiber, and the fabric is produced through pre-shrinking, alkali reduction, fiber opening, pre-setting, napping, dyeing and other processes to produce suede fabric. [0003] Generally, most of the microfiber filament leather-feeling fabrics need to be processed by chemical fiber spinning and post-finishing dyeing. For example, Chinese Patents No. 83109961, No. 76102732, No. 79108906, No. 8110032, and No. 200410000690.7 are to dye the superfiber fibers of the fabric after chemical fiber opening and mechanical opening. Since the suede fabric is made of polyester sea-island fiber, polyester nylon microfiber and ot...
