Description

Technical Field

[0001] The utility model relates to the technical field of protective textiles, in particular to a cut-resistant fabric. Background Art

[0002] Cut-resistant fabrics are widely used in military, aviation, security, fire protection, and industrial fields. In security, cut-resistant fabrics are usually used to wrap important parts such as arms, palms, necks, chests, and backs; in industrial production, cut-resistant products can effectively protect workers from damage by machines, tools, and products, such as handling glass and machining metal; in daily life, occupations such as gardening and floristry also have a need for cut-resistant fabrics.

[0003] The cut resistance of fabrics directly determines the cut resistance of products. For the selection of fabric yarn materials, aramid and ultra-high molecular weight polyethylene are the two most widely used materials. The fabric structure design is an important part of fabric preparation and has a great influence on fabric performance. According to the current research on the yarn cut resistance mechanism, the yarn cut resistance mechanism is different at different cutting angles. Cutting tests were carried out at different angles between the yarn and the blade. The results showed that when the angle between the yarn and the blade was 60°, the yarn had the best cut resistance; when the angle was 0°, the yarn was easily "split" and had the worst cut resistance. The arrangement of yarns in the fabric will directly affect the fabric's cut resistance. In the actual application of cut-resistant products, it is impossible to predict from which angle the wearer will be cut. Therefore, it is an urgent problem to improve the safety of cut-resistant products by changing the fabric structure.

[0004] In view of this, the present utility model is proposed. Utility Model Content
