Problems solved by technology

Light-colored micropowders include metal sulfides and halides such as copper sulfide and cuprous iodide; white micropowders include metal oxides such as tin oxide, zinc oxide, and silver oxide. This type of antistatic agent has good heat resistance and long-lasting antistatic effect. Not affected by climatic conditions, but poor compatibility with resin, large amount of addition, high cost, and color, difficult to spin or dye

Embodiment Construction

[0037] The present invention is further described below in conjunction with specific embodiment: present embodiment implements under the premise of technical solution of the present invention, has provided detailed implementation and process, but protection scope of the present invention is not limited to following embodiment.

[0038] refer to figure 1 , a kind of antistatic nylon staple fiber, is prepared by following method:

[0039] (1) Nylon 6 chips and antistatic masterbatch are mixed in a weight ratio of 90-99: 1-10;

[0040] (2) Enter the above-mentioned mixture into a screw extruder with electric heating function through a feed bin, so that the slices are molten;

[0041] (3) The above-mentioned molten material is quantitatively pressed into the spinning assembly through a metering pump, ejected from the spinneret, and the spun filaments are cooled and crystallized to obtain primary growth filaments;

[0042] (4) After the process of winding, falling into barrel, cl...

Abstract

The invention relates to a process for producing full nylon leather base fabric, comprising the following steps: (1) using nylon 6 slices as the raw material, adding antistatic master batches into the nylon slices and preparing antistatic nylon 6 short fibers by the following steps: melting and extruding by using a screw compressor, spinning, beaming, adjusting spinning finish formula and improving the finishing mode during finishing, drying and setting, cutting and the like; and (2) preparing the antistatic nylon 6 short fibers of the step (1) into the full nylon leather base fabric by adopting a needle-punched nonwoven fabric production process. The invention has the advantage that the full nylon leather base fabric prepared by the process for producing full nylon leather base fabric has the advantages of good flexibility, high tensile failure strength, good hydroscopic property, good skin feeling as well elasticity and the like compared with the regular nylon polyester blended leather base fabric.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a production process of an all-nylon leather base cloth. Background technique [0002] Since the beginning of the 21st century, with the scarcity of natural leather resources and the rapid development of synthetic leather technology, more nonwoven products have been well applied, especially products represented by needle-punched leather base fabrics. Its inherent imitation leather structure is recognized by more leather manufacturers and customers. At present, 240 million meters of needle-punched leather base fabrics are needed every year in China alone, and some high-end products need to be imported. [0003] As the medium and high-end products of synthetic leather, such as medium and high peeling products, most of them are made of polyester-nylon fiber blends, microfibers or post-treatment of needle-punched leather base fabrics. These medium and high-grade synthetic leathers ...
