Problems solved by technology

Since the ultra-high molecular weight polyethylene fiber has a tow-like structure, and each ultra-high molecular weight polyethylene fiber is an independent individual, the warping process of each fiber is complicated and the production cost is high. It is easy to cause defects such as broken wires, twisting, winding and knotting, and uneven arrangement. These defects will hinder the effective energy transmission of unidirectional or weft-free fabrics to external forces, and prone to stress concentration, thereby reducing the quality of unidirectional or weft-free fabrics. The strength and bulletproof performance of non-woven fabrics

Embodiment 1

[0063] Such as figure 1 As shown, a kind of unidirectional cloth preparation method provided in this embodiment comprises:

[0064] Step S101, continuously spreading multiple ultra-high molecular weight polyethylene films or strips sequentially along one direction;

[0065] Step S102, connecting each piece of the ultra-high molecular weight polyethylene film or strip into one to obtain the unidirectional fabric.

[0066] The core idea of ​​this embodiment is to use ultra-high molecular weight polyethylene films or strips to directly replace traditional ultra-high molecular weight polyethylene fibers to prepare unidirectional fabrics.

[0067] A plurality of ultra-high molecular weight polyethylene films or strips are continuously spread sequentially along the width direction of the ultra-high molecular weight polyethylene film or strip, and the width direction is perpendicular to the molecular chain stretching direction of the ultra-high molecular weight polyethylene film or ...

Embodiment 2

[0084] The unidirectional fabric provided in this embodiment includes: a plurality of ultra-high molecular weight polyethylene films or strips that are successively spread in one direction and connected to each other.

[0085] In this embodiment, the ultra-high molecular weight polyethylene film is a thin sheet made of ultra-high molecular weight polyethylene with a certain width and thickness, and the width is much larger than the thickness. The strips are divided by stretching the film. The strip-shaped flakes formed by the cutting process have a width smaller than that of the film and a thickness equivalent to that of the film. Ultra-high molecular weight polyethylene film or strip itself has a certain width and thickness. It is an integral structure without joint points or cutting lines. It has high strength, large modulus, and low creep. The influence range of stress concentration and so on.

[0086] Optionally, the direction is the width direction of the ultra-high mole...

Embodiment 3

[0095] Such as Figure 5 As shown, the present embodiment provides a method for preparing a weft-free fabric comprising:

[0096] Step S201, multiple unidirectional fabrics are sequentially cross-composited at a certain angle;

[0097] Step S202, laminating multiple pieces of cross-composited unidirectional fabrics into one to obtain the non-weft fabric.

[0098] The unidirectional fabric includes: multiple ultra-high molecular weight polyethylene films or strips that are continuously spread in one direction and connected to each other.

[0099] Optionally, multiple pieces of unidirectional fabrics are sequentially cross-laminated at a certain angle, including:

[0100] Multiple pieces of unidirectional fabrics are sequentially laid and laid crosswise at a certain angle, and the overlapped parts of the multiple pieces of unidirectional fabrics are hot-pressed or glued.

[0101] If the method of gluing is adopted, glue is applied to one side of the unidirectional cloth and n...

Abstract

The invention provides a unidirectional fabric, a non-woven fabric, preparation methods of the fabrics and a non-woven fabric product. The preparation method of the unidirectional fabric comprises the following steps: sequentially continuously spreading a plurality of ultra high molecular weight polyethylene films or strips along one direction; and connecting the ultra high molecular weight polyethylene films or strips to form a whole body to obtain the unidirectional fabric. The non-woven fabric prepared on the basis of the unidirectional fabric and the product prepared on the basis of the non-woven fabric are high in strength and excellent in bulletproof property; the preparation method are simple and are low in cost.

Description

technical field [0001] The invention relates to a chemical fiber cloth, in particular to a unidirectional cloth, a weft-free cloth, a preparation method thereof, and a weft-free cloth 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 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 characteristics of ultra-high molecular weight polyethylene fibers are superior to aramid fibers, and are widely used in the field of military and police bulletproo...
