Production process of wear-resistant anti-slip safety belt

Abstract

The invention discloses a production process of a wear-resistant anti-slip safety belt. The method includes: drawing Nylon fibers and polyester fibers, wherein the strand number ratio of the two kinds of yarn strips in the drawing process is 1:2; preparing two kinds of card slivers with the counts of 20S and 41S, further processing the card slivers into drawn slivers, and processing the drawn slivers into rough yarns with the same count and different twists; and spinning the roving into spun yarns with a certain special number, and spooling the blended spun yarns. By adopting a three-layer composite fabric form, the tensile property and the safety performance of the safety belt are improved, the anti-skid fabric layer is provided with linear stripes and the friction force is increased by adjusting the section diameters of the warp yarns and the weft yarns, and the phenomenon of slipping when the safety belt is manually adjusted is effectively improved; by padding the wear-resistant liquid, the molecular structure can be effectively prevented from being damaged, so that the wear-resistant effect is achieved, the safe use performance is improved, the use cost is reduced, and the energy is saved.

Description

technical field [0001] The invention relates to the technical field of safety belts, in particular to a production process of a wear-resistant anti-slip safety belt. Background technique [0002] Seat belts are safety parts used on equipment. They are ribbons used to ensure safety when flying aircraft such as airplanes or performing high-altitude operations and performing arts. Seat belts have become the primary safety issue for drivers and passengers. One of the most important properties such as; [0003] The existing safety belts are mainly made of polyester, polypropylene, nylon and other materials. The safety belts must be used with metal bayonets. Every time you use them, you need to adjust the length of the safety belts. However, it is easy to adjust the safety belts manually. Slipping and other phenomena occur, and after a period of use, the surface of the seat belt will be subject to sliding wear due to long-term fastening with the bayonet, resulting in surface fluf...
