Wet towel production equipment, process and wet towel

Abstract

Wet towel production equipment comprises an unreeling unit, a humidifying unit, a cutting unit and a rubbing unit. The unreeling unit is used for unreeling non-woven fabrics, the humidifying unit is arranged at the rear of the unreeling unit and used for humidifying the unreeled non-woven fabrics, so that a primary wet towel with certain wettability is formed, the cutting unit is disposed at the rear of the humidifying unit, and is used for cutting the primary wet towel into a towel with a preset size so that the towel can be packaged, the rubbing unit is disposed between the unreeling unit and the humidifying unit or disposed between the humidifying unit and the cutting unit, is provided with rubbing grooves arranged in advance, and is used for rubbing the non-woven fabrics or the primary wet towel, accordingly, the arrangement direction of fibers in the non-woven fabrics or the primary wet towel turns, simultaneously, the fibers in the non-woven fabrics or the primary wet towel are bent and deform along with the rubbing grooves arranged in advance, and patterns corresponding to the rubbing grooves arranged in advance are formed on the non-woven fabrics or the primary wet towel. The invention further relates to wet towel production process and a wet towel.

Description

technical field [0001] The invention relates to wet tissue production equipment, technology and wet tissue. 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 ...

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

[0005] As the basic material for the production of wet wipes, the phenomenon of "cloud spots" or fiber bundles appearing on the fiber web of non-woven fabrics will cause hard lumps in the finished wet wipes and seriously affect the use of wet wipes, and the relatively poor quality of non-woven fabrics The isotropic property will also make the tear resistance of the wet wipe product different in the vertical and horizontal directions, making the wet wipe prone to damage during use
