Problems solved by technology

This method needs to unwind and unwind the finished non-woven fabric roll that has been wound into an independent package and onto the carded fiber web, so continuous production cannot be achieved, and there are seams between the rolls; the fiber web and the non-woven fabric are superimposed When it is reinforced by spunlace, the spunlace composite fabric produced by this method has hard hand feeling, poor softness and poor air permeability due to the entanglement of the non-woven fabric itself.

Embodiment 1

[0016] The viscose fiber is weighed, and is laid into a fiber web with a certain gram weight and strength through the opening and cleaning system 1 and the carding system 2; A web with a certain weight and strength. Then, the fiber web is laminated with the fiber web online, and after 2 to 8 high-speed fine water jets with a water pressure of 10 bar to 160 bar (that is, the spunlace system 3), the fibers are entangled and reinforced. It passes through the drying system 4 at a temperature of 160°C, and finally passes through the coiling system 5 to make a spunlace composite non-woven fabric.

Embodiment 2

[0018] The antibacterial fiber is weighed, and it is laid into a fiber web with a certain gram weight and strength through the opening and cleaning system 1 and carding system 2; the viscose fiber and polyester fiber are weighed according to a certain mixing ratio, and the opening and cleaning system 1', carding The web forming system 2' paves a fiber web with a certain grammage and strength. Then, the fiber web is laminated with the fiber web online, and after 2 to 8 high-speed fine water jets with a water pressure of 10 bar to 160 bar (that is, the spunlace system 3), the fibers are entangled and reinforced. It passes through the drying system 4 at a temperature of 160°C, and finally passes through the coiling system 5 to make a spunlace composite non-woven fabric.

Embodiment 3

[0020] The chitin fiber is weighed and laid into a fiber web with a certain gram weight and strength through the opening and cleaning system 1 and the carding system 2; the viscose fiber is weighed and laid through the opening and cleaning system 1' and the carding system 2' A fiber net with a certain weight and strength. Then, the fiber web is laminated with the fiber web online, and after 2 to 8 high-speed fine water jets with a water pressure of 10 bar to 160 bar (that is, the spunlace system 3), the fibers are entangled and reinforced. It passes through the drying system 4 at a temperature of 160°C, and finally passes through the coiling system 5 to make a spunlace composite non-woven fabric.

Abstract

The production process of hydro-entangled composite non-woven fabric includes fiber opening and carding to form fiber nets and superposing fiber nets in at least two sets of opening system and at least two sets of carding and netting system; twisting and reinforcing fiber inside one hydro-entangling system; and stoving. The production process is simple and high in production efficiency, and can realize continuous production. The product is soft in hand feeling and homogeneous.

Description

technical field [0001] The invention relates to a production method of spunlace composite nonwoven fabric. Background technique [0002] Spunlace is a high-tech non-woven fabric technology with great development prospects. It uses high-pressure, high-speed, fine water to spray the fiber web, and at the same time, the dual function of rebounding water column interspersed by the trawl net makes the fibers entangled with each other and the fiber web can be reinforced. A spunlace nonwoven is formed. Because of its soft texture, high strength, good air permeability and moisture absorption, and the cloth quality is close to traditional textiles, spunlace non-woven fabrics are widely used and will become a key project for technological innovation and development. At the same time, with the continuous improvement of people's living standards and production technology, higher requirements are put forward for the function and performance of non-woven fabrics. The research and develo...
