Problems solved by technology

[0003] At the same time, in the fur industry, the top layer of cowhide is usually treated as waste because of its fineness, which results in a large waste of raw materials.
Moreover, the discarded top layer of cowhide is also likely to cause environmental pollution.

Embodiment 1

[0042] The spunlace web forming process includes the following steps:

[0043] A. Material preparation: choose ordinary leather fiber webs and non-woven fabrics;

[0044] B. High-pressure spunlace: Lay the above-mentioned leather fiber web on the non-woven fabric and keep the two in surface contact, and then use an ordinary spunlace machine to spray the leather fiber web at high pressure. Under the action of high-pressure water flow, the leather fiber web part Embedded in the non-woven fabric, so that the leather fiber net and the non-woven fabric are stably entangled with each other to obtain a blank;

[0045] C, drying: drying the above blank;

[0046] D. Winding: wind the dried billet on the storage cylinder;

[0047] E: Slitting: Move the storage cylinder with blanks from the winding station to the cutting station, and then cut the wound blanks into finished spunlace nonwovens of a set length at the cutting station cloth.

[0048] The pre-spunlace pressure in step B is...

Abstract

The invention provides a spun-laced net formation technology and a slitting device thereof, and belongs to the technical field of machines. The problem that in the prior art, the stability is not highis solved. The spun-laced net formation technology comprises the following steps of 1, preparing materials, 2 performing high-pressure spunlacing, 3 drying, 4 winding and 5 slitting. The slitting device comprises a driving piece, a limiting structure and a slicer, a storage cylinder is cylindrical, the outer side of the storage cylinder is provided with a plurality of cutting grooves sunken in the axial direction, the slicer comprises an annular tool apron and a plurality of blades fixedly connected to the tool apron, the tool apron is connected to a rack, and the tool apron is right oppositeto the end of the storage cylinder. The spun-laced net formation technology is easy to implement and high in finished product quality and the slitting device is high in stability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a hydroentangling web forming process and a cutting device thereof. Background technique [0002] Spunlace non-woven fabric is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The obtained fabric is spunlace non-woven fabric. Its fiber raw materials come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. [0003] At the same time, in the fur industry, the first layer of cowhide is usually treated as waste due to its fine fragmentation, which causes a large degree of waste of raw materials. Moreover, the discarded top layer of cowhide is also likely to cause environmental pollution. Contents of the invention [0004] The f...
