Abstract

The invention discloses an anti-stretching spunlace non-woven fabric and production equipment thereof, wherein the anti-stretching spunlace non-woven fabric comprises a first high-strength non-woven fabric layer, a first thermal bonding composite fiber layer, a first anti-stretching layer, a second high-strength non-woven fabric layer, a second anti-stretching layer, a second thermal bonding composite fiber layer, a third high-strength non-woven fabric layer, a third thermal bonding composite fiber layer and a fourth thermal bonding composite fiber layer; according to the invention, the two anti-stretching layers are arranged, so that the non-woven fabric is not easy to crack under the action of tensile force. The invention is provided with special production equipment which is matched with the production of the spunlace nonwoven fabric, and the equipment is simple and the production efficiency is high.

Description

Stretch-proofing water thorn non-woven fabrics and production facility thereof
Technical Field
The invention relates to the technical field of spinning, in particular to an anti-stretching spunlace non-woven fabric and production equipment thereof.
Background
The non-woven fabrics, because the production process need not to weave and get the name, all have the application in many fields, because its mode of production is different, therefore the non-woven fabrics has multiple kind, but no matter which kind of non-woven fabrics, its stretch-proofing effect all remains to be promoted, is not fit for the use in some occasions, consequently need cooperate other materials to use.
Disclosure of Invention
The invention aims to provide a stretch-resistant spunlace nonwoven fabric to solve the problems in the background technology.
In order to solve the technical problems, the invention adopts the following technical scheme: a stretch-resistant spunlace non-woven fabric comprises a first high-strength non-woven fabric layer, a first thermal bonding composite fiber layer, a first stretch-resistant layer, a second high-strength non-woven fabric layer, a second tensile-resistant layer, a second thermal bonding composite fiber layer, a third high-strength non-woven fabric layer, a third thermal bonding composite fiber layer and a fourth thermal bonding composite fiber layer; a second high-strength non-woven fabric layer is arranged between the first high-strength non-woven fabric layer and the third high-strength non-woven fabric layer; a first tensile-resistant layer is arranged between the first high-strength non-woven fabric layer and the second high-strength non-woven fabric layer; the first tensile-resistant layer is connected with the first high-strength non-woven fabric layer through the first thermal-bonding composite fiber layer; a second tensile layer is arranged between the second high-strength non-woven fabric layer and the third high-strength non-woven fabric layer; the second tensile layer is connected with the third high-strength non-woven fabric layer through the second thermal bonding composite fiber layer; the second high-strength non-woven fabric layer is connected with the first tensile layer and the second tensile layer through a third thermal bonding composite fiber layer and a fourth thermal bonding composite fiber layer; the first high-strength non-woven fabric layer, the second high-strength non-woven fabric layer and the third high-strength non-woven fabric layer have the same structure and are composed of an upper fiber net, a lower fiber net and a middle carbon fiber layer; the first tensile layer and the second tensile layer have the same structure and comprise a plurality of protruding parts and a plurality of lower concave parts; the periphery of the protruding part is provided with a lower concave part; the periphery of the lower concave part is provided with a protruding part; the first tensile layer and the second tensile layer are provided with thermal bonding composite fiber blocks above the protruding part and below the concave part, and the thermal bonding composite fiber blocks above the protruding part of the first tensile layer form a first thermal bonding composite fiber layer; the thermal bonding composite fiber block under the concave part of the second tensile layer forms a second tensile layer; forming a third thermal bonding composite fiber layer by the thermal bonding composite fiber block below the lower concave part of the first tensile layer; the mass of thermally bondable composite fibers above the protrusions of the second tensile layer forms the second tensile layer.
Further, the production method of the high-strength non-woven fabric layer comprises the following steps: the method comprises the steps of mixing and opening bamboo fibers, hemp fibers and ES fibers, carding the bamboo fibers, hemp fibers and ES fibers into a net through a carding machine to obtain a fiber net, drafting the fiber net through a drafting machine, laying a carbon fiber layer after the drafted fiber net is laid, laying a layer of fiber net on the carbon fiber layer, and then feeding the fiber net into a spunlace area to form the non-woven fabric.
