Rubbing roller, embossing process applying rubbing roller and embossed wet tissue prepared by embossing process

Abstract

The invention relates to a rubbing roller, which comprises an upper rubbing roller and a lower rubbing roller, wherein a plurality of bulges are arranged on the upper rubbing roller, a plurality of grooves are arranged on the lower rubbing roller, the bulges of the upper rubbing roller are matched with the grooves of the lower rubbing roller so as to extend into the grooves, the space between the two central points of the two adjacent bulges is 5-10mm, the area of the cross section of each bulge is gradually reduced from the position close to the center of the upper rubbing roller to the position far away from the center of the upper rubbing roller, the horizontal section of each bulge is ladder-shaped, each bulge has a top end surface, the area of the top end surface is 1-20mm<2>, and the height of each bulge is 0.05-5mm. The invention also provides an embossing process applying the rubbing roller, and embossed wet tissue prepared by the embossing process.

Description

technical field [0001] The invention relates to a rubbing roller, an embossing process using the rubbing roller, and an embossed wet wipe prepared by using the embossing process. Background technique [0002] At present, most of the substrates of wet wipes on the market are non-woven fabrics. Non-woven fabric, also known as non-woven fabric, refers to the cloth made without traditional spinning, weaving or knitting. It is formed into a net, then consolidated by spunlace, needle punching or hot rolling, and finally finished to form a non-woven fabric. It is a new type of fiber product that is breathable, light in weight and environmentally friendly. [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. Forming fiber bundles or fiber blocks, thes...

AI Technical Summary

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, which leads to a larger ratio of MD / CD (that is, a relatively large longitudinal and transverse strength), which makes the tear resistance of non-woven products in the longitudinal and transverse directions different.
