Problems solved by technology

However, before the non-woven process, traditional textiles are formed by yarn processing, and the structure is relatively stable. It is difficult for the non-woven process to change the arrangement of the fiber structure inside the textile, thus limiting the relationship between the textile process and the non-woven process. Combined effect of craft
[0004] However, cotton slivers, rovings, etc. are semi-finished products of the spinning process, which are single fiber-like aggregates formed by fiber webs gathered, drafted, and twisted by a sliver and arranged relatively regularly. The parts of these semi-finished products are similar to The structure of nonwoven materials, however, because the fibers only rely on frictional cohesion, the strength is usually very low

Embodiment 1

[0026] Such as figure 1 As shown, the present embodiment provides a kind of preparation method of the non-woven material based on spinning semi-finished product, and described non-woven material is processed by the cotton fiber sliver of spinning mill as raw material, and present embodiment first quantifies The cotton slivers of 27g / 5m are arranged according to the warp density of 5 pieces / 10cm as the warp strips, and the weft strips are introduced according to the plain weave structure for weaving to obtain interwoven fabrics with a weft density of 5.5 pieces / 10cm, and then the interwoven fabrics are sent to Enter the acupuncture machine for pre-acupuncture, and the acupuncture frequency is 300r / min.

[0027] Make preliminary reinforcement, and then the product after pre-acupuncture undergoes 1 main acupuncture reinforcement forming, the acupuncture frequency is 600r / min; the final product weight is 500g / m 2 .

Embodiment 2

[0030] This embodiment provides a method for preparing non-woven materials based on spinning semi-finished products. The non-woven materials are processed from raw cotton fiber slivers in spinning mills. The preparation method is as follows: first, quantitatively 30g / 5m cotton slivers are arranged according to the warp density of 5 pieces / 10cm as the warp strips, and the weft strips are introduced according to the plain weave structure for weaving to obtain interwoven fabrics with a weft density of 5 pieces / 10cm, and then the interwoven fabrics are fed into Acupuncture machine was used for pre-acupuncture, and the frequency of acupuncture was 300r / min. Make the initial reinforcement, and then the product after needle punching is reinforced by two front and back spunlaces, the pressure of the spunlace head is 80bar and 100bar respectively; finally, the final product is obtained after drying and finishing, with a grammage of 550g / m 2 .

Embodiment 3

[0032] This embodiment provides a method for preparing non-woven materials based on spinning semi-finished products. The non-woven materials are processed from polyester-cotton 65 / 35 fiber blended raw slivers in spinning mills. The preparation method is : First, the polyester-cotton 65 / 35 fiber blended raw slivers that are quantitatively 25g / 5m are arranged according to the warp density of 8 / 10cm as the warp strips, and the weft strips are introduced into the weft strips according to the plain weave structure for weaving, and the weft density is 8 / 10cm. 10cm interlaced fabric, and then the interlaced fabric is sent to the needling machine for pre-acupuncture, and the needling frequency is 300r / min. Make the preliminary reinforcement, and then the product after acupuncture is reinforced by two front and back spunlaces, the pressure of the spunlace head is 80bar and 120bar respectively; finally, the final product is obtained after drying and finishing, with a grammage of 650g / m ...

Abstract

The invention provides a preparation method of a non-woven material based on a semi-finished textile. The method comprises the following steps of arranging a certain quantity of strip-shaped products of the semi-finished textile according to a certain density as warp-wise strips, and introducing weft-wise strips according to a certain weave structure for weaving to obtain a mixed fabric with a certain warp-weft density; and then pre-needling the mixed fabric in a needling machine to realize preliminary reinforcement, then performing 1-2 times of main needling or spunlacing or hot rolling reinforcement forming on a needled product, or directly performing spunlacing winding web fixing forming or hot rolling web fixing forming on the mixed fabric, and finally performing after-finishing to obtain the final product. The semi-finished product is formed in a sheet shape through an interweaving technology, and then the sheet is fixed and formed through a non-woven web fixing technology of needling or spunlacing or hot rolling; a certain structural appearance and basic mechanical performance are achieved; the technology is simple and easy to implement, and the production process is environmentally friendly and free of pollution; and prepared products are rich and diversified in variety and can be applied to thermal insulation materials, decorative materials, home furnishing materials and the like.

Description

technical field [0001] The invention relates to the technical field of nonwoven materials, in particular to a method for preparing nonwoven materials based on spinning semi-finished products. Background technique [0002] Nonwoven material is a kind of fiber aggregate material made without traditional spinning and weaving, which is formed by friction, cohesion, entanglement and bonding between fibers; the main characteristics of nonwoven material different from textiles are The main body of its composition is a single fiber, while the main body of textiles is yarn. With the continuous development of my country's nonwoven industry, interdisciplinary, molding technology innovation and composite integration technology have been widely used in the development of nonwoven products, and a large number of environmentally friendly, multifunctional nonwoven materials and differentiated nonwoven products have been developed. [0003] Usually, the combination of textile technology and...
