Manufacturing machine for non-woven fabric

Abstract

The invention relates to a manufacturing machine for non-woven fabric. The manufacturing machine has the advantages that the structural components of the manufacturing machine are different from those of an existing manufacturing machine for the non-woven fabric; endless tow raw materials are parallelly laid in the warp direction, the weft direction and the oblique angle direction between warps and wefts, bending is avoided, wide-band whole-row filament clamping and drawing are performed, interlayer chopped filaments are placed automatically, binder is sprayed automatically, automatic filament chopping is performed, and adhesive paper tape is used to adhered and fix the filaments; non-woven prepreg fabric can be produced; filament quality damage hardly exists during production, high efficiency and low cost are achieved, breadth is set freely, and filament layers or arranging sequences in the fabric can be set freely; the non-woven fabric manufactured by the manufacturing machine comprises carbon fiber non-woven fabric and plastic-based and ceramic-based reinforcing materials, the density of manufactured composite fiber filaments is increased, the tensile strength of the manufactured composite fiber filaments is increased, the manufactured composite fiber filaments has new distortion resistance, the interlayer shearing force of the manufactured composite fiber filaments is increased, and wide application range is achieved.

Description

technical field [0001] The invention relates to a non-woven fabric manufacturing machine and its manufacturing method and principle. Background technique [0002] In the field of non-woven fabric manufacturing, flat soft materials are mainly used, and holes are formed by needle punching to form non-woven fabrics, which are not suitable for use as reinforcing materials in high-strength composite materials; currently, carbon fibers and glass fibers are interwoven as the main reinforcing materials. cloth, and warp knitted multi-directional cloth. The bending caused by interwoven fabric and interlacing reduces the tensile strength, the gap increases, the base material increases, and the weight increases, but there is no tensile strength in the oblique direction of warp and weft. The warp knitted multi-directional fabric, due to the bending produced by weaving, reduces the tensile strength, the gap increases, the base material increases, and the weight increases. The above-ment...

Problems solved by technology

Warp knitted multi-directional fabric, due to the bending caused by weaving, the tensile strength decreases, the gap increases, the base material increases, and the weight increases, and the weaving thread makes the warp and weft tensile strength low
