Problems solved by technology

[0004] Since ultra-high molecular weight polyethylene fibers have a filamentous structure (single filament fineness is about 2.5 denier), in the process of preparing various products based on ultra-high molecular weight polyethylene fibers, it is necessary to arrange multiple fibers with filamentary structures separately. The process is complicated, the cost is high, and in the process of product preparation, the surface of the fiber is prone to burrs due to friction, and the fibers are prone to breakage, twisting, winding, etc., which is not conducive to the overall uniform force of multiple fibers, resulting in The overall strength is often lower than the strength of multiple ultra-high molecular weight polyethylene fibers, and the strength utilization rate is low

example 3

[0069] Example 3: A plurality of single yarns can be arranged and connected in one direction to form a single yarn product with a single layer structure.

[0070] For example: a plurality of single yarns can be arranged in parallel along the length direction of the single yarns, and connected as a whole by non-interweaving methods such as binding connection, adhesive bonding or hot pressing connection, to prepare unidirectional fabric 801 (such as Figure 8 ). The unidirectional fabric prepared by this scheme can be used but not limited to the preparation of products such as reinforced structural parts, high-strength bags, bulletproof panels, impact-resistant panels, bulletproof helmets, bulletproof and riot-proof bags, etc., which can better meet the requirements of these products on fabric strength, weight, bulletproof, etc. and other special requirements for performance.

example 4

[0071] Example 4: A plurality of single-layer structures obtained by unidirectional arrangement and connection of multiple single yarns can be cross-laminated at a certain angle to obtain a single-yarn product with a multi-layer structure.

[0072] Among them: the intersection angle of any adjacent two single-layer structures can be the same, and the intersection angle can be any angle from 0 to 90 degrees, such as: the intersection angle is 45 degrees; or the intersection angle is 90 degrees, such as multi-layer The unidirectional fabric 801 is laminated sequentially at 0 / 90 degrees crosswise, and each layer of unidirectional fabric is glued or connected by heat and pressure, thus making a weft-free fabric 901 (such as Figure 9 ) and other single yarn products with multi-layer structure. The single-yarn product produced by this solution has high strength, and when subjected to strong external impact such as bullet injection, the force-bearing point can be diffused into a for...

Abstract

The invention relates to a single yarn, a manufacturing method of the single yarn, single yarn products and a manufacturing method of the single yarn products. The manufacturing method of the single yarn includes bundling or bundling and twisting ultra-high molecular weight polyethylene films or strips to obtain the single yarn. The single yarn product at least comprises a body made with the single yarn. The single yarn made by bundling or bundling and twisting the ultra-high molecular weight polyethylene films or strips replaces traditional ultra-high molecular weight polyethylene fibers in developing and manufacturing various products. The single yarn has the advantages, such as wear resistance, impact resistance, corrosion resistance and ultraviolet resistance, similar to those of the ultra-high molecular weight polyethylene fibers; the single yarn further has the unique advantages, such as good structural integrity, high strength, high utilization rate of strength, high productivity, low manufacturing cost, light weight and low linear density. Therefore, the single yarn can replace the traditional ultra-high molecular weight polyethylene fibers in manufacturing the various products and is widely applicable.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a single yarn, a single yarn product and a preparation method thereof. Background technique [0002] Ultra High Molecular Weight Polyethylene (UHMW-PE) is a thermoplastic engineering plastic with a linear structure and excellent comprehensive properties. Making high-strength fibers based on this material is one of its most important uses . [0003] Ultra-high molecular weight polyethylene fiber is a high-performance fiber, which has the advantages of high strength, wear resistance, impact resistance, corrosion resistance, and ultraviolet resistance. It can be widely used in many fields. For example: ultra-high molecular weight polyethylene fiber can be used to prepare The civilian fields such as ropes, fishing nets and various fabrics can be applied to the preparation of personal protective products such as bulletproof vests and bulletproof helmets, and can also be use...
