Problems solved by technology

The disadvantage is that it feels poor, heavy, difficult to stick to the wall, and easy to fall off
The advantage of wallpaper is that it is easy to paste and not easy to fall off, but it is easy to warp, airtight, and easy to make the wall moldy
Therefore, the quality of existing wall coverings and wallpapers has been unable to meet people's needs, and there is an urgent need for a new production method for wall coverings to improve the quality of wall coverings.

Embodiment 1

[0019] A kind of manufacture method of spunlace nonwoven fabric wall covering, described spunlace nonwoven fabric wall covering comprises substrate layer and printing layer, and the manufacturing steps of this wall covering are as follows:

[0020] a) Select 100% 1.5Daniel*38MM polyester to make 125g / square meter, open it through the opener, mix it evenly in the cotton mixing box, and then comb through the carding machine to comb a small piece of fiber pile into a Fiber cotton webs arranged side by side, and then laid by a cross-lapper, so that the carded fiber cotton webs are arranged in a three-dimensional disorder;

[0021] b) The fiber cotton web is first drawn by the drafting machine, and then passed through 5 high-pressure spunlaces, the pressures are 85bar, 70bar, 90bar, 100bar, 110bar, and then the fiber cotton web is vacuum dehydrated, dried, and high temperature The substrate layer is formed after four processes of pressing and shaping. The pressing temperature is 18...

[0025] A kind of manufacture method of spunlace nonwoven fabric wall covering, described spunlace nonwoven fabric wall covering comprises substrate layer and printing layer, and the manufacturing steps of this wall covering are as follows:

[0026] a) Select 50% 1.5Daniel*38MM and 50% 0.8Daniel*38MM polyester to make 130g / square meter, open it through the opener, mix it evenly in the cotton mixing box, and then comb it through the carding machine, and put a small piece The small fiber piles are combed into fiber cotton webs arranged side by side, and then laid by a cross lapper to make the carded fiber cotton webs arranged in a three-dimensional disorder;

[0027] b) The fiber cotton web is first drawn by the drafting machine, and then passed through 5 high-pressure spunlaces, the pressures are 75bar, 70bar, 90bar, 105bar, 105bar, and then the fiber cotton web is vacuum dehydrated, dried, and high temperature The substrate layer is formed after four processes of pressing and s...

Embodiment 3

[0031] A kind of manufacture method of spunlace nonwoven fabric wall covering, described spunlace nonwoven fabric wall covering comprises substrate layer and printing layer, and the manufacturing steps of this wall covering are as follows:

[0032] a) Select 100% 0.8Daniel*38MM polyester to make 140g / square meter, open it through the opener, mix it evenly in the cotton mixing box, and then comb through the carding machine to comb a small piece of fiber pile into a Fiber cotton webs arranged side by side, and then laid by a cross-lapper, so that the carded fiber cotton webs are arranged in a three-dimensional disorder;

[0033] b) The fiber cotton web is stretched by the drafting machine first, and then passed through 4 high-pressure spunlaces with pressures of 100bar, 80bar, 105bar, and 110bar respectively, and then the fiber cotton web is vacuum dehydrated, dried, and pressed at high temperature in sequence. The substrate layer is formed after four processes of shaping and sh...

Abstract

The invention relates to a manufacturing method of a spunlaced nonwoven wall covering fabric. The manufacturing method comprises the following steps: a) selecting dacron, opening the selected dacron through an opening machine, uniformly mixing the opened dacron through a cotton mixing box, then carding the mixed dacron through a carding machine so as to form a fiber cotton fleece of which lines are arrayed one by one and side by side, and performing three-dimensional mussy arraying on the carded fiber cotton fleece; b) firstly enabling the fiber cotton fleece to pass through a draw machine, then enabling the fiber cotton fleece to pass through a high-pressure spunlace, and then successively performing vacuum dewatering, drying, high-temperature pressing and forming on the obtained fiber cotton fleece so as to form a base material layer; and c) uniformly stirring a high-temperature foaming agent, aqueous PU, a color fixing agent and color paste so as to obtain a mixture, filtering the mixture to form paste, uniformly coating and printing the paste on one smooth clean surface of the base material layer, then coating a small quantity of a water-proof material and a small quantity of a flame-retardant material on the paste, and finally enabling a foaming printing layer to be formed after circular net foaming treatments. The wall covering fabric prepared by the manufacturing method disclosed by the invention is firm to stick, good in air permeability and not liable to be mouldy.

Description

technical field [0001] The invention relates to a method for manufacturing a spunlace nonwoven wall covering. Background technique [0002] Existing wall coverings are produced in the form of woven cloth, made of warp and weft yarns. The advantage is that it is powerful. The disadvantage is that it feels poor, heavy, difficult to stick to the wall, and easy to fall off. The advantage of wallpaper is that it is easy to paste and not easy to fall off, but it is easy to warp, airtight, and easy to make the wall moldy. Therefore existing wall cloth and wallpaper quality all can't satisfy people's demand, be badly in need of a kind of new wall cloth production method to improve wall cloth quality. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a method for manufacturing spunlace non-woven wall coverings. The wall coverings produced by the method are firmly pasted, have good air pe...
