Non-woven fabric and process for producing same

A manufacturing process and non-woven technology, applied in the field of non-woven fabrics and their manufacturing processes, can solve problems such as large differences in tear resistance and large MD:CD ratios, so as to reduce cloud spots or fiber bundles. The difference in tear resistance, the effect of increasing the number of fiber arrangements

Problems solved by technology

In the existing non-woven fabric process, in the fiber web after carding, most of the fibers will be arranged along the longitudinal direction (MD direction), while the fibers arranged in the transverse direction (CD direction) are relatively small. Less, resulting in a larger ratio of MD:CD, making the tear resistance of non-woven products in the longitudinal and transverse directions significantly different

Embodiment Construction

[0020] Please also see Figure 1 to Figure 6 As shown, the non-woven fabric manufacturing process flow provided by the embodiment of the present invention includes the following steps.

[0021] (1) Provide fiber raw materials, and open the fiber raw materials.

[0022] In the general non-woven fabric manufacturing process, before the fiber raw material is carded and laid, it is necessary to use an opener to open the fiber raw material.

[0023] In this embodiment, the fiber opening unit 10 is used to open the fiber raw material. Its working principle is to tear and loosen non-woven materials such as fiber and cotton through the relative movement between machines, so that large entangled fibers can be loosened into small pieces or bundles. In particular, when one or several different fiber raw materials need to be mixed according to different proportions according to the design requirements of the product, sending the mixed fiber raw materials to the opener for full opening c...

Abstract

The invention relates to a process for producing a non-woven fabric, comprising the following steps: providing fiber used as a raw material, and carding the fiber to form a fiber net; consolidating the fiber net to form a primary non-woven fabric; providing a rubbing unit with preset rubbing grooves, and rubbing the primary non-woven fabric by using the rubbing unit so as to change the distribution direction of fiber in the primary non-woven fabric, reduce the vertical and horizontal strength ratio of the primary non-woven fabric and meanwhile bend and deform the fiber in the primary non-woven fabric along with the preset rubbing grooves. The invention also relates to the non-woven fabric produced by adopting the process. Compared with the prior art, the process for producing the non-woven fabric adopts the rubbing unit to rub the consolidated primary non-woven fabric so as to obtain the non-woven fabric with an uniform fiber structure and patterns on the surface.

Description

technical field [0001] The invention relates to a non-woven fabric and a manufacturing process thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, refers to the cloth made without traditional spinning, weaving or knitting. It is a new type of fiber product with soft, breathable and planar structure, which is formed into a net, then consolidated by spunlace, needle punching or hot rolling, and finally finished. [0003] However, in the actual production process, the fiber raw materials carded into single fibers by the carding machine will be reassembled due to the influence of the way of laying and the size, type and electrostatic properties of the fibers themselves during the laying process. Fiber bundles or fiber clusters, so that the so-called "cloud spot" or fiber bundle phenomenon appears on the formed fiber web, destroying the uniformity of the fiber web, and when such a fiber web undergoes subsequent consolidation processes to form...
