Fiber net wet forming technology and special device thereof

Abstract

The invention relates to a fiber net wet forming technology and a special device thereof. A forming net in forming equipment is arranged to be slant; a spunlace device is arranged in the forming equipment; a spunlace head of the spunlace device is arranged above the slant forming net; by pre-spunlacing a fiber net in the forming net, the product strength and the tensile strength are improved while the softness and the comfort of the product are enhanced on the premise of not adding other soft fiber raw materials with high cost, so that the occurrence of a tear phenomenon is prevented when the fiber net is transferred to subsequent processes, and normal execution of the subsequent processes is facilitated.

Description

technical field [0001] The invention relates to a manufacturing technology of non-woven fabrics, in particular to a wet-state forming technology of fiber webs of non-woven fabrics and a special device thereof. Background technique [0002] The manufacturing process of non-woven fabrics is generally the opening and mixing of fiber raw materials → carding, forming a fiber web on a forming machine → spunlace entanglement and reinforcement → printing, dyeing and other post-processing processes → drying → winding into products. In order to further improve the air permeability and softness of non-woven products, technicians in the industry try to add various fiber materials with high softness or high air permeability, such as silk fiber and pearl fiber. For example, the invention patent of Chinese patent application number 201110441037.4 discloses a production process of silk fiber spunlace nonwoven fabric, which uses 50% (weight percentage) of silk fiber and 50% (weight percentag...

AI Technical Summary

Problems solved by technology

But there are also several problems: first, the use of silk fibers and tencel fibers each accounting for 50% by weight as raw materials undoubtedly increases a large part of the cost of raw materials; second, although the manufactured non-woven fabrics are soft and Comfortable, but the strength of its products only comes from the entanglement force between fibers generated during the spunlace process, and the obtained products are easily pulled and split; third, during the production process, due to the silk in the wet fiber web The entanglement of fibers and Tencel fibers is relatively small. When the fiber web is transferred between various processes, the operator must observe it from time to time to prevent the fiber web from being torn and piled up when it is transferred between processes, which will affect the quality of the product.
