Embodiment 1

[0030] (1) Use short fibers of white polyester sea-island superfine fibers and colored bamboo charcoal fibers in a weight ratio of 1:0.5 as raw materials. After opening and carding, the two fibers are fully mixed, and then laid by cross-lapping to form 23g / m 2 mixed fiber web.

[0031] (2) The short fibers of white superfine fibers and colored bamboo charcoal fibers are respectively laid by opening, carding and cross-lapping to form superfine fiber nets and bamboo charcoal fiber nets, and then the bamboo charcoal fiber nets are laid on the superfine fiber nets Surface formation 28g / m 2 composite fiber layer.

[0032] (3) After performing basic hydroentanglement reinforcement on the front and back of the mixed fiber web prepared in step (1) or the composite fiber layer prepared in step (2), adjust the structure of the water needle to be a regular polygon, with a density of 6 per square centimeter and 20bar pressure to carry out fancy hydroentanglement on the composite fiber...

Embodiment 2

[0035] (1) Use short fibers of white polyester sea-island superfine fibers and colored bamboo charcoal fibers in a weight ratio of 1:2 as raw materials. After opening and carding, the two fibers are fully mixed, and then laid by cross-lapping to form 25g / m 2 mixed fiber web.

[0036] (2) The short fibers of white superfine fibers and colored bamboo charcoal fibers are respectively laid by opening, carding and cross-lapping to form superfine fiber nets and bamboo charcoal fiber nets, and then the bamboo charcoal fiber nets are laid on the superfine fiber nets Surface formation 30g / m 2 composite fiber layer.

[0037] (3) After performing basic hydroentanglement reinforcement on the front and back of the mixed fiber web prepared in step (1) or the composite fiber layer prepared in step (2), adjust the structure of the water needle to be a regular polygon, with a density of 8 per square centimeter and 36bar pressure to carry out fancy spunlace on the composite fiber web or the...

Embodiment 3

[0040] (1) Use short fibers of white polyester sea-island superfine fibers and colored bamboo charcoal fibers in a weight ratio of 1:1 as raw materials. After opening and carding, the two fibers are fully mixed, and then laid by cross-lapping to form 24g / m 2 mixed fiber web.

[0041] (2) The short fibers of white superfine fibers and colored bamboo charcoal fibers are respectively laid by opening, carding and cross-lapping to form superfine fiber nets and bamboo charcoal fiber nets, and then the bamboo charcoal fiber nets are laid on the superfine fiber nets Surface formation 29g / m 2 composite fiber layer.

[0042] (3) After performing basic hydroentanglement reinforcement on the front and back of the mixed fiber web prepared in step (1) or the composite fiber layer prepared in step (2), adjust the structure of the water needle to be a regular polygon, with a density of 7 per square centimeter and 24bar pressure to carry out fancy hydroentanglement on the composite fiber w...

Abstract

The invention provides a patterned non-woven fabric with concave-convex patterns and a preparing method of the patterned non-woven fabric. The preparing method comprises the following steps that firstly, short fibers of superfine fibers and bamboo carbon fibers are opened and carded to be fully mixed, and then the mixed fibers are laid into a mixed fiber net in a crossed net laying mode; secondly, short fibers of the superfine fibers and bamboo carbon fibers are laid into a superfine fiber net and a bamboo carbon fiber net respectively in the mode of opening, carding and crossed net laying, and then the bamboo carbon fiber net is laid on the surface of the superfine fiber net to form a composite fiber layer; thirdly, the front and back sides of the mixed fiber net prepared in the first step or the front and back sides of the composite fiber layer prepared in the second step are subjected to basic spunlace reinforcing, then the structure and number of spunlace stitches are adjusted, and a fiber net containing initial surface texture is obtained after dehydration and pre-drying; fourthly, the fiber net, containing the initial surface texture, prepared in the third step passes through a concave-convex hot roller with the concave-convex rugged surface, drying and sizing are carried out, and the patterned non-woven fabric with the concave-convex patterns is obtained.

Description

Technical field: [0001] The invention belongs to the technical field of sanitary products, and in particular relates to a fancy non-woven fabric with concavo-convex patterns and a preparation method thereof. Background technique: [0002] With the continuous improvement of people's living standards, people's requirements for health, convenience and beauty are also getting higher and higher. Therefore, the subdivision of personal care products is also increasing. Disposable wet wipes based on non-woven fabrics have dominated the market. Among them, the non-woven fabrics used for baby cleaning have the appearance of washed cloth, but only the commonly used ones Half the thickness of the washed cloth, strong water absorption, good air permeability, easy to use, loved by a wide range of consumers. [0003] The reason why non-woven fabrics can occupy the disposable cleaning market is that its appearance and certain aspects of performance are similar to woven fabrics, but it is n...
