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 will be further explained below in conjunction with specific examples: this example is implemented on the premise of the technical solution of the present invention, and detailed implementation manners and processes are given, but the protection scope of the present invention is not limited to the following examples.

[0038] Reference figure 1 , An antistatic nylon staple fiber prepared by the following method:

[0039] (1) Mix nylon 6 chips with antistatic masterbatch in a weight ratio of 90~99:1~10;

[0040] (2) The above mixture is fed into the screw extruder with electric heating function through the silo to make the slices melt;

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

[0042] (4) The nascent yarn is wound, doffed, bundled, drafted, pre-oiled, crimp...

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 thenylon 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 hasthe 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 a full nylon leather base cloth. Background technique [0002] Since entering 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 artificial leather structure has been recognized by more leather manufacturers and customers. At present, 240 million meters of needle-punched leather base cloth is needed every year in China alone, and some high-end products need to be imported. [0003] As middle and high-end synthetic leather products, such as medium and high-peel products, most of them are made of polyester-nylon fiber blends, super fiber production or some post-processing of needle-punched leather base fabric. These mid-to-high-end synthetic leathers have the ex...
