Problems solved by technology

Its shortcomings: First, the traditional punching technology, which is composed of negative pressure dehydration device, high-pressure generating system, high-pressure spray head, polyester woven support net, transmission frame and other equipment. The installed capacity of this machine is 515KW, and the power The power consumption is very large, accounting for 50% of the power consumption of the entire assembly line; second, due to the restriction of the weaving technology of the polyester woven mesh supplier, it is impossible to achieve any shape of the woven mesh; The replacement cost is high, ab...

Embodiment 1

[0016] Embodiment 1: with reference to attached Figure 1~3 . The spunlace non-woven fabric punching die has a plurality of protruding bumps 1 on the template of the punching die 10, and a plurality of dehydrating small water holes 2 are distributed on the template between the multiple protruding bumps. Punching die 10 is sleeve shape (see attached Figure 4 Drum punching die 10 in the middle) or plate shape (see attached figure 1 ) or arc-shaped (see attached figure 2 and 3 ). The punching mold 10 is made mold earlier, then adopts metal material (copper, copper alloy, stainless steel, titanium alloy, zinc alloy, aluminum alloy etc.) Metal materials (such as plastics, nylon, etc.) are injection-molded or compression-molded, and its manufacturing process is a prior art, which will not be described here.

Embodiment 2

[0017] Embodiment 2: On the basis of Embodiment 1, the protruding bumps 1 on the template of the punching die 10 are tapered.

Embodiment 3

[0018] Embodiment 3: On the basis of Embodiment 1, the protruding bumps 1 on the template of the punching die 10 are arc-shaped.

Abstract

The present invention relates to a hydro-entangled non-woven fabric production method by using the components of perforation die, prepunching machine and hydropunching drum, etc. belonging to the field of non-woven fabric production equipment and its production method. On the die plate of said perforating die there are several projected salient points, several dehydrating small holes are distributed between said several projected salient points on the die plate. Said invention can make the cotton layer pass through the prepunching hydropunching machine and perforation channel formed from drum perforation die and hydropunching jet head and undergo the processes of prewetting, entanglement and hydropunching so as to obtain the invented product.

Description

Technical field: [0001] The invention relates to a production method composed of a spunlace non-woven fabric punching die, a pre-puncture machine, a spunlace rotary roller, etc., and belongs to the field of non-woven fabric production equipment and production methods. Background technique: [0002] The products produced by the spunlace non-woven production line equipment are widely used in industrial base fabrics, medical supplies, civil hygiene materials and other fields because of their excellent physical properties, which promotes the rapid development of the industry. According to incomplete statistics, as of In 2005, there were more than 80 production lines nationwide, and the production capacity increased from 2,000 tons in 1994 to 800,000 tons per year. The original punching technology relies on polyester woven mesh imported from Japan, the United States, and Germany. Through a spunlace machine specially designed for punching, high-pressure (10-20Mpa) water is used to...
