Problems solved by technology

[0003] At present, in order to make the nonwoven fabric products have a certain strength by the spunlace method, the grammage is usually relatively large, and the strength of the product with a low grammage cannot meet the needs of users. In addition, the nonwoven fabrics prepared by the spunlace method currently Severe fluffing and uneven surface affect the safety and skin-friendly feeling of the cloth, especially when used as medical and sanitary products, these problems should be avoided

Embodiment 1

[0045] The present embodiment provides a kind of spunlace nonwoven fabric production process, comprises the following steps:

[0046] S1: Weigh the viscose fiber and polyester according to the mass ratio of 1:1 and put them into the net conveying curtain, then pass through the coarse opening device for coarse opening and mixing, and then send them to the fine opening device for fine opening and mixing, and then Send to the cotton storage box and mix thoroughly;

[0047] S2: Send the fiber after opening and mixing in S1 to the air pressure cotton box, and after being processed, it will be uniformly matted and output, and then it will be carded into a web, cross-laid, and drafted to obtain a formed fiber web; The stretch ratio is 3.0.

[0048] S3: Perform pre-wetting treatment on the formed fiber web in S2; the pre-wetting treatment adopts a double-net clamping type, the mesh size of the lower mesh is 70 mesh, the mesh size of the upper mesh is 40 mesh, and the water pressure i...

Embodiment 2

[0052] The present embodiment provides a kind of spunlace nonwoven fabric production process, comprises the following steps:

[0053] S1: Weigh the viscose fiber and polyester according to the weight ratio of 2:1 and put them into the net conveying curtain, then pass through the coarse opening device for coarse opening and mixing, and then send them to the fine opening device for fine opening and mixing, and then Send to the cotton storage box and mix thoroughly;

[0054] S2: Send the fiber after opening and mixing in S1 to the air pressure cotton box, and after being processed, it will be uniformly matted and output, and then it will be carded into a web, cross-laid, and drafted to obtain a formed fiber web; The stretch ratio is 3.0.

[0055] S3: Perform pre-wetting treatment on the formed fiber web in S2; the pre-wetting treatment adopts a double-net clamping type, the mesh size of the lower mesh is 70 mesh, the mesh size of the upper mesh is 40 mesh, and the water pressure...

Embodiment 3

[0059] The present embodiment provides a kind of spunlace nonwoven fabric production process, comprises the following steps:

[0060] S1: Weigh the viscose fiber and put it on the conveying curtain, then pass through the coarse opening device for rough opening and mixing, then send it to the fine opening device for fine opening and mixing, and then send it to the cotton storage box for full mixing ;

[0061] S2: Send the fiber after opening and mixing in S1 to the air pressure cotton box, and after being processed, it will be uniformly matted and output, and then it will be carded into a web, cross-laid, and drafted to obtain a formed fiber web; The stretch ratio is 3.0.

[0062] S3: Perform pre-wetting treatment on the formed fiber web in S2; the pre-wetting treatment adopts a double-net clamping type, the mesh size of the lower mesh is 70 mesh, the mesh size of the upper mesh is 40 mesh, and the water pressure is 10KG.

[0063] S4: Send the formed fiber web pre-wetted in S...

Abstract

The invention relates to the technical field of nonwoven fabrics, in particular to a spunlaced nonwoven fabric production technology and an application thereof. The spunlaced nonwoven fabric production technology comprises processes of opening and mixing, carding to form webs, cross lapping, drafting, pre-wetting, spunlace reinforcement and the like. By regulating type, proportion, denier, pre-wetting treatment process parameters and reinforcement treatment process parameters of fibrous materials, the spunlaced nonwoven fabric production technology relieves the phenomenon of pilling of nonwoven fabric prepared by an existing spunlace method, prepared nonwoven fabric products have flat surfaces, touch soft and are not prone to pilling, the strength of low-gram-weight nonwoven fabric products is improved, so that the pull rate of products is up to 95% or above, and the products can be applied to medical and sanitary products.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a production process of spunlace nonwoven fabrics and its application. Background technique [0002] Spunlace, also known as hydrojet and hydroentangling, is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. It is the main method for preparing nonwoven fabrics at present. Nonwoven fabrics made by spunlace have good hygroscopicity and air permeability, and are soft to the touch. They are often used to make medical and sanitary products such as baby wipes, beauty masks, masks, and protective clothing. [0003] At present, in order to make the nonwoven fabric products have a certain strength by the spunlace method, the grammage is usually relatively large, and the strength of the product with a low grammage cannot meet the needs of users. In a...
