Colorful spunlace nonwoven fabric fadeless when being wetted and manufacturing method

Abstract

The invention relates to a colorful spunlace nonwoven fabric fadeless when being wetted and a manufacturing method. The colorful spunlace nonwoven fabric has a spunlace nonwoven fabric reinforcing rib function and a color showing function A colored PP spunlace non-woven fabric and fiber in the spunlace non-woven fabric covering upper and lower layers are mutually twined to form the colorful spunlace nonwoven fabric. The colorful spunlace nonwoven fabric has the advantages that the colorful spunlace nonwoven fabric is environment-friendly, free of pollution, high in color fastness and small in chromatic aberration, does not fade, does not easily sensitize a human body, keeps attractive colors and the flexibility and comfort degree of a spunlace non-woven fabric material, solves the mechanical damage problem that the spunlace non-woven fabric material easily breaks transversely and produces the unexpected technical effect; the adopted manufacturing method is simple, and zero-cost production can be achieved by utilizing an existing device.

Description

technical field [0001] The invention relates to a colorful non-fading spunlace nonwoven fabric with the function of reinforcing ribs of the spunlace nonwoven fabric and the function of color display and a production method thereof, belonging to the field of manufacturing colored spunlace nonwoven materials. 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 ...

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.
