Problems solved by technology

[0005] The above-mentioned technology is complex and cumbersome to process ultra-high molecular weight polyethylene fibers. In the process of forming the fabric, each single layer needs to be hot-pressed and consolidated separately. The polymer properties of a single layer will cause a certain degree of damage, thereby reducing the strength, bulletproof and other properties of the fabric prepared from multiple single layers

preparation example Construction

[0048] The embodiment of the present application provides a kind of preparation method of fabric, such as figure 1 Shown, the preparation method of described fabric comprises:

[0049] S101: Continuously and parallelly spreading multiple ultra-high molecular weight polyethylene films or strips in sequence to form a single layer.

[0050] Ultra-high molecular weight polyethylene film is a sheet made of ultra-high molecular weight polyethylene with a certain width and thickness, and the width is much larger than the thickness. The ultra-high molecular weight polyethylene strips can be prepared independently or can be strip-shaped sheets formed by cutting the film before and after stretching. The width of the strip is smaller than the width of the film, and the thickness is equivalent to or smaller than the thickness of the film. The ultra-high molecular weight polyethylene film or strip provided by the application is different from the ultra-high molecular weight polyethylene f...

Embodiment 1

[0073]Adopt ultra-high molecular weight polyethylene film to prepare fabric, wherein ultra-high molecular weight polyethylene film width is 120mm, thickness is 0.025mm, linear density is 19000D, breaking strength is 27 g / denier, and tensile modulus is 1600 g / denier, The elongation at break was 1.9%. The number of sheets of ultra-high molecular weight polyethylene film required for a single layer can be determined according to the width of the required single layer and the width of a single ultra-high molecular weight polyethylene film. Adjacent to parallel spreading to form a single layer, 32 pieces of the above-mentioned ultra-high molecular weight polyethylene films are successively laid on the single layer to form another single layer, and the laying angle of the ultra-high molecular weight polyethylene films of two adjacent single layers is 90 degrees After the two single layers are laid, the ultra-high molecular weight polyethylene tape with a linear density of 300D is us...

Embodiment 2

[0077] The fabric is prepared by using ultra-high molecular weight polyethylene strips, wherein the ultra-high molecular weight polyethylene strips have a width of 50mm, a thickness of 0.012mm, a linear density of 5000D, a breaking strength of 29 grams per denier, and a tensile modulus of 1800 grams per denier. denier, the elongation at break was 1.8%. The number of sheets of ultra-high molecular weight polyethylene strips required for a single layer can be determined according to the width of the required single layer and the width of a single ultra-high molecular weight polyethylene strip, such as 24 pieces of the above-mentioned ultra-high molecular weight polyethylene strips The tapes are spread in parallel with a small gap (less than 2mm) to form a single layer, and 24 pieces of the above-mentioned ultra-high-weight polyethylene strips are successively laid on the single layer to form another single layer. The laying angle of the molecular weight polyethylene strip is 90 ...

Abstract

The application discloses a fabric and its preparation method and a protective product, wherein the preparation method of a fabric comprises: sequentially and continuously spreading a plurality of ultra-high molecular weight polyethylene films or strips in parallel to form a single layer; Continuously spread multiple sheets of ultra-high molecular weight polyethylene films or strips on the formed single layer to form another single layer; repeat this step until N stacked single layers are formed, wherein the N single layers At least two adjacent single layers intersect at a certain angle, and N is an integer greater than or equal to 2; the N single layers are bound up and down as a whole by using binding yarns. The fabric provided by the application has better properties such as stretching, tensile resistance and impact resistance, and the protective products prepared based on the fabric have better bulletproof properties.

Description

technical field [0001] The application relates to the technical field of application of polymer materials, in particular to a fabric, a preparation method thereof, and a protective product. 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 (UHMW-PE) fiber is a kind of synthetic fiber, its molecular structure has a high degree of straightening parallelism and orientation, this molecular structure determines that UHMW-PE fiber has extremely high strength and Modulus, and has good chemical stability, corrosion resistance and other advantages. The above-mentioned characteristics of ultra-high molecular weight polyethylene (UHMW-PE) fibers have surpassed aramid fiber plain weave fabrics, and are widely used in t...
