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 production process for spunlace nonwovens, comprising the following steps:

[0046] S1: The viscose fiber and polyester are weighed according to the mass ratio of 1:1 and then put into the screen conveyor, then the coarse opening and mixing are carried out by the coarse opening device, and then sent to the fine opening device for fine opening and mixing, and then Send to the cotton storage box and mix thoroughly;

[0047] S2: The fibers after opening and mixing in S1 are sent to the air pressure cotton box, processed into a uniform cotton feast and output, and then carded into a web, cross-lapped, and drawn to obtain a forming fiber web; The stretch ratio is 3.0.

[0048] S3: Pre-wet the formed fiber web in S2; the pre-wet treatment adopts a double-mesh clamping type, the number of lower meshes is 70 meshes, the number of upper meshes is 40 meshes, and the water pressure is 10KG.

[0049] S4: The formed fiber web pre-wetted in S3 is s...

Embodiment 2

[0052] The present embodiment provides a production process for spunlace nonwovens, comprising the following steps:

[0053] S1: The viscose fiber and polyester are weighed according to the weight ratio of 2:1 and then put into the screen conveyor, and then the coarse opening and mixing are carried out by the coarse opening device, and then sent to the fine opening device for fine opening and mixing, and then Send to the cotton storage box and mix thoroughly;

[0054] S2: The fibers after opening and mixing in S1 are sent to the air pressure cotton box, processed into a uniform cotton feast and output, and then carded into a web, cross-lapped, and drawn to obtain a forming fiber web; The stretch ratio is 3.0.

[0055] S3: Pre-wet the formed fiber web in S2; the pre-wet treatment adopts a double-mesh clamping type, the number of lower meshes is 70 meshes, the number of upper meshes is 40 meshes, and the water pressure is 10KG.

[0056] S4: The formed fiber web pre-wetted in S...

Embodiment 3

[0059] The present embodiment provides a production process for spunlace nonwovens, comprising the following steps:

[0060] S1: The viscose fiber is weighed and put into the net conveying curtain, then the coarse opening and mixing are carried out by the coarse opening device, and then sent to the fine opening device for fine opening and mixing, and then sent to the cotton storage box for full mixing ;

[0061] S2: The fibers after opening and mixing in S1 are sent to the air pressure cotton box, processed into a uniform cotton feast and output, and then carded into a web, cross-lapped, and drawn to obtain a forming fiber web; The stretch ratio is 3.0.

[0062] S3: Pre-wet the formed fiber web in S2; the pre-wet treatment adopts a double-mesh clamping type, the number of lower meshes is 70 meshes, the number of upper meshes is 40 meshes, and the water pressure is 10KG.

[0063] S4: The formed fiber web pre-wetted in S3 is sent to the spunlace area for reinforcement treatmen...

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 non-woven fabrics, in particular to a production process and application of a spunlace non-woven fabric. Background technique [0002] Spunlace, also known as hydro-jetting and hydro-entangling, is to spray high-pressure fine water flow onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs are reinforced and have a certain strength. It is the main method for preparing non-woven fabrics at present. The non-woven fabric obtained by the spunlace method has good hygroscopicity, air permeability and soft feel, and is often used to manufacture medical and sanitary products such as baby wipes, beauty masks, masks, and protective clothing. [0003] At present, the non-woven fabric prepared by spunlace method has a certain strength, and its gram weight is usually large, and the strength of the product with low gram weight cannot meet the needs of users. The cloth ha...
