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

[0018] Please also see Figure 1 to Figure 5 , The non-woven fabric manufacturing equipment 100 provided by the embodiment of the present invention includes a fiber opening unit 10 , a carding and laying unit 20 , a consolidation unit 30 , a kneading unit 40 , a drying unit 50 and a winding unit 60 .

[0019] The fiber opening unit 10 mainly uses the relative movement between machines to tear and loosen non-woven materials such as fibers and cotton, so as to loosen large entangled fibers into small pieces or bundles. In this embodiment, according to different product requirements, one or several different fiber raw materials may be mixed in different proportions and sent to the fiber opening unit 10 for full opening.

[0020] It should be noted that the fiber opening unit 10 used in the present invention can be any fiber opening mechanism that can be applied in the non-woven fabric production process.

[0021] It can be understood that, according to different non-woven fabric...

Abstract

The invention relates to non-woven fabric manufacturing equipment which comprises a carding and net laying unit, a consolidating unit and a rubbing unit. The carding and net laying unit is used for carding a fiber used as a raw material to form a fiber net; the consolidating unit is arranged behind the carding and net laying unit and used for consolidating the fiber net to form a primary non-woven fabric; and the rubbing unit is arranged behind the consolidating unit, provided with preset rubbing grooves and used for rubbing the primary non-woven fabric to change the distribution direction of the fiber in the primary non-woven fabric and 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 non-woven fabric manufacturing equipment adopts the rubbing unit to rub the consolidated primary non-woven fabric so as to obtain the non-woven fabric with a uniform fiber structure and patterns on the surface.

Description

technical field [0001] The invention relates to a non-woven fabric manufacturing equipment. 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 a non-woven...
