Problems solved by technology

[0002] Using mulberry fiber as raw material, when producing non-woven silk products, during mechanical processing, the friction between fibers and between fibers and machine parts will generate static electricity. The parts have opposite charges, and the silk fibers are adsorbed and wound on the parts, which hinders the normal operation of the equipment, thereby restricting the normal operation of the production line; at the same time, the characteristics of mulberry silk fibers are different from those of other natural fibers and chemical fibers. Belonging to polymer compounds, relatively thin, soft, and extremely low dielectric constant, it is a poor conductor of electricity (see attached table); in the electrical properties of silk fibers, the problem of static electricity is the two opposite physical processes of charge generation and dissipation.

Embodiment 1

[0017] The following is the production process of non-woven silk products:

[0018] 1. Select the electrolyte and NNO anionic surfactant with good hygroscopicity as the antistatic agent, and prepare the antistatic agent wet solution with a concentration of 2%-3% according to the volume percentage;

[0019] 2. Start the automatic humidification system to control the relative humidity of the production workshop environment at 85%-90%. Because the relative humidity is less than 85%, the moisture in the raw material volatilizes into the air, the moisture regain decreases, and the electrical conductivity decreases accordingly. If the relative humidity is greater than 90%, the silk fibers will be wetted, and the fibers will stick to the parts and be difficult to separate during mechanical processing;

[0020] 3. Spread the 5-8cm degreased and degummed mulberry short fibers in layers in a plastic container of 2m×0.8m×0.4m, and the weight ratio of the mulberry short fibers and the an...

Abstract

The invention provides an antistatic humidification technique for non-woven real silks, the invention formulates 2-3% of an anion surfactant solution as an antistatic humidification liquid to regain the moisture of 5-8cm of mulberry silk short fiber so that the moisture regaining rate is 20-25%, and still places the short fiber for 12-18 hours to be then mechanically processed in a production environment with 85%-90% of the air relative humidity. By adding control on the relative humidity in the production environment and the antistatic humidification technique for raw materials, the production conditions of non-woven real silk products taking 100% of the mulberry silk fiber as the raw material are met, the pure real silk products are upgraded and the application field of the real silk products is widened.

Description

technical field [0001] The invention relates to a production process of non-woven non-woven fabrics, in particular to an anti-static and wet-feeding treatment process for non-woven silk products. Background technique [0002] Using mulberry fiber as raw material, when producing non-woven silk products, during mechanical processing, the friction between fibers and between fibers and machine parts will generate static electricity. The parts have opposite charges, and the silk fibers are adsorbed and wound on the parts, which hinders the normal operation of the equipment, thereby restricting the normal operation of the production line; at the same time, the characteristics of mulberry silk fibers are different from those of other natural fibers and chemical fibers. Belonging to polymer compounds, relatively thin, soft, and extremely low dielectric constant, it is a poor conductor of electricity (see attached table); in the electrical properties of silk fibers, the problem of st...
