Colorful wet tissue without color fading in wet and manufacturing method

Abstract

The invention relates to a colorful wet tissue without color fading in wet and a manufacturing method. The colorful wet tissue without the color fading in the wet has the function of a spunlaced non-woven wet tissue and also has the function of showing colors. The colorful spunlaced non-woven wet tissue is formed by mutually interlacing colorful PP spunlaced non-woven fabric and fibers in spunlaced non-woven fabric covering the upper face layer and the lower face layer of the colorful PP spunlaced non-woven fabric. The colorful wet tissue without the color fading in the wet and the manufacturing method have the advantages that environment protection and zero pollution are achieved, colors cannot fade, color fastness is high, color differences are small, allergies to human bodies cannot be caused easily, attractiveness of colors is reserved, the softness and the comfortableness of the spunlaced non-woven materials are maintained, the big flaw that the spunlaced non-woven materials crack easily in the transverse direction is overcome, unexpected technical effects are achieved, the manufacturing method is simple, and zero cost production can be achieved by using existing equipment.

Description

technical field [0001] The invention relates to a multi-color non-fading wet tissue with the function of spunlace non-woven wet tissue reinforcing ribs and color display and a production method thereof, belonging to the field of color spun-lace non-woven material manufacturing. Background technique [0002] 1. The traditional production method of colored spunlace nonwovens needs to go through dyeing or printing process, which will produce "three wastes" and pollute the environment. [0003] 2. The color paste, color fixing agent, and adhesive used in traditional dyed and printed spunlace nonwoven materials basically contain formaldehyde, and contact with human skin will cause sensitization and other health effects. [0004] 3. Traditional dyed and printed spunlace nonwoven materials are prone to fading when exposed to water, organic solvents, and wet wipe essence, so they cannot be used as wet wipe materials. [0005] 4. Traditionally dyed or printed spunlace nonwoven mater...

AI Technical Summary

Problems solved by technology

[0002] 1. The traditional production method of colored spunlace nonwovens needs to go through dyeing or printing process, which will produce "three wastes" and cause pollution to the environment

[0003] 2. The color paste, color fixing agent, adhesive, etc. used in traditional dyeing and printing spunlace nonwoven materials basically contain formaldehyde, which will cause sensitization and other health effects in contact with human skin

[0004] 3. Traditional dyed and printed spunlace nonwoven materials are prone to fading when exposed to water, organic solvents, and wet wipe essence, so they cannot be used as wet wipe materials

[0005] 4. Traditionally dyed or printed spunlace nonwoven materials will cause batch-to-batch color differences due to factors such as slurry batches and finishing temperatures. The color difference is generally 2-5, which affects product appearance quality and use value

[0006] 5. The vertical and horizontal strength of the spunlace wet wipe material under the traditional direct laying process has a large difference, and the horizontal strength is generally low

Its disadvantages: the non-woven fabric formed by monochromatic spunbonded filaments can neither play the role of reinforcing ribs nor achieve the purpose of making colorful non-woven fabrics.
