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 nylon microfiber filament:

[0021] Component A is nylon 6, the mass percentage is 90%, and the crystallinity is 85%;

[0022] Component B is a monomeric polymer of isophthalic acid and methanol, with a mass percentage of 10% and a crystallinity of 30%.

[0023] The composite spinning method is adopted, and the spinning temperature is 200°C-250°C, and the crimping speed is 3000-3200m / min. The cross-sectional schematic diagram of the produced nylon superfine fiber filament 100D / 24F*24 is shown in figure 1 , the fiber comprises a middle nylon polymer A and polymer B surrounding polymer A in the form of a sea. As shown in the figure, there are 21 circles of component A in the fiber surrounded by B (single fiber fineness is about 0.2dtex), indicating that the number of islands in the fiber is 21. In actual production, the number of islands can be 20-30 , the shape can be a circle or other shapes.

Embodiment 2

[0031] Component A and component B raw materials are as follows:

[0032] Component A is nylon 66, with a mass percentage of 95% and a crystallinity of 90%;

[0033] Component B is a monomeric polymer of isophthalic acid and ethylene glycol, with a mass percentage of 5% and a crystallinity of 15%.

[0034] The preparation method is the same as in Example 1. The main indicators of the finished leather-feeling fabric finished product are as follows:

[0035] Color fastness to rubbing: grade 3.5 for dry grinding, grade 3 for wet grinding; color fastness to washing: grade 3.5 for water immersion, grade 3 for staining; color fastness to soaping: grade 3.5 for water immersion, grade 3.5 for staining.

Abstract

The invention relates to a nylon superfine fiber filament. A single fiber 1F is composed of 20-30 filament-shaped (about 0.2dpf) component A and component B surrounded and filled in the periphery of component A and in the void; The mass percentage of component A is 85% to 95%, and the mass percentage of component B is 5% to 15%; the crystallinity of component A is 70% to 90%, and the crystallinity of component B is 5% to 40%; the beneficial effects of the present invention are mainly reflected in: using the nylon ultra-fine fiber filament of the present invention to manufacture the leather-feeling base fabric, adopting low-temperature treatment to open the fiber, raising and sanding treatment, and dyeing with acid dye at 80-120°C , easy to color, will not produce dyeing sewage, will not cause dyeing pollution to the environment, reduces energy consumption, and greatly improves product quality.

Description

(1) Technical field [0001] The invention relates to a nylon superfine fiber filament and a method for making leather-feeling fleece fabric by using the nylon superfine fiber filament. (2) Background technology [0002] Microfiber filament fabrics are now more and more widely used in people's lives, mainly used in men's and women's high-end casual jackets, wind, casual suits, trousers, casual cotton clothes, casual down jacket fabrics. Generally, it is mainly made of sea-island microfiber filament or polyester nylon microfiber filament. The fabric is produced through pre-shrinking, alkali reduction, fiber opening, presetting, napping, dyeing and other processes to produce this kind of leather-feeling 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 th...
