Embodiment Construction

[0022] The most critical idea of ​​the present invention is: the 100% bleached cotton fiber is prepared by direct laying and carding to prepare the straight laying parallel fiber cotton web and the cotton web of the three-dimensional distribution is prepared by air-laid carding of 100% bleached cotton fiber together, through one-step method water The thorns are combined with double-layer cotton nets, so that the obtained double-layer diversion cotton spunlace nonwoven fabric has a double-layer diversion structure, which has the effect of diverting liquid and blocking back seepage. The invention adopts the physical arrangement of fibers to obtain the performance of the product and highlights the concept of environmental protection.

[0023] Concrete present invention adopts following technical scheme:

[0024] It has a double-layer flow-guiding all-cotton spunlace nonwoven fabric, which is composed of two layers of fiber webs arranged in different ways, including a layer of par...

Abstract

The invention relates to a double-layer flow-guiding all-cotton spunlaced nonwoven fabric and a preparation method thereof. The prepared nonwoven fabric comprises a planar diffusion parallel network layer and a three-dimensional fiber network layer with down-absorption function, and the two layers of network are both Composed of 100% bleached cotton fibers, the double-layer diversion type adopts two physical arrangements of fibers to obtain a double-layer diversion structure, forming a more obvious interlayer layer, which plays the role of diverting liquid and blocking back seepage effect, to achieve the performance of the product. It has a double-layer diversion type cotton spunlace nonwoven fabric with thin thickness, no chipping, soft, skin-friendly, environmentally friendly, not easy to deform, good wear resistance, strong liquid diversion suction, and has the effect of blocking liquid back seepage , Improve the comfort of the end product.

Description

technical field [0001] The invention relates to the technical field of sanitary protective products, in particular to a cotton spunlace nonwoven fabric and a preparation method thereof. Background technique [0002] The production technology of spunlaced nonwovens is to use high-pressure water to spray and puncture the fibers entering the spunlace machine on the supporting screen, so that the fibers are displaced and turned by the action of water needles from top to bottom and the action of reflected water needles at the bottom. It is an emerging technology that is extruded and intertwined to strengthen into cloth. Because spunlace nonwovens have many performance characteristics such as good hand feeling, softness and not easy to fall off, the production scale of spunlace nonwovens in China has developed rapidly for more than 20 years. At present, there are more than 200 domestic spunlace production lines, including about 40 imported lines, with a total production capacity ...
