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.

Embodiment 1

[0015] Embodiment 1: with reference to attached figure 1 and 2 . A colorful and non-fading spunlaced nonwoven fabric. The colored PP nonwoven fabric 2 is entangled with the fibers 1 in the wood pulp paper covering it and the fibers 101 in the nonwoven fabric 3 below to form a colored nonwoven fabric. The color non-woven fabric surface shows the color PP color. The colored PP nonwoven fabric 2 is a colored PP spunbonded nonwoven material. The colored PP nonwoven fabric 2 can be colored monochromatic, or multi-colored.

Embodiment 2

[0016] Embodiment 2: On the basis of embodiment 1, the colored spunlace nonwoven fabric surface shows the colored PP color and the spunlace nonwoven fabric fiber is mixed in the colored PP color.

Embodiment 3

[0017] Example 3: On the basis of Example 1, a method for making a colorful and non-fading spunlaced nonwoven fabric, the first step is to open the wood pulp paper 1 and the nonwoven fabric 3, and after opening After the fibers are fluffy and mixed, they are carded on the machine and interlaced with the fibers to form the lower spunlace nonwoven fiber preparation layer; the second step is carried out simultaneously with the first step, and the colored PP spunbond base fabric is unrolled and rolled into the machine; the third The first step is to superimpose the upper layer of wood pulp paper, the middle layer of colored PP spunbond base fabric, and the lower layer of spunlace nonwoven fiber preparation layer together and then enter the machine for spunlace. The nonwoven surface fibers after spunlace show the coloring of colored PP; In the fourth step, the spunlace colored non-woven fabric is dried in the machine; in the fifth step, it is wound up after drying.

Abstract

The invention relates to colorful fastness spunlaced non-woven fabric and a manufacturing method. The colorful fastness spunlaced non-woven fabric has the function of non-woven fabric strengthening ribs and also has the function of showing colors. The colorful fastness spunlaced non-woven fabric is formed by mutually interlacing colorful PP spunlaced non-woven fabric, fibers in wood pulp paper covering the colorful PP spunlaced non-woven fabric and fibers in spunlaced non-woven fabric on the lower face of the colorful PP spunlaced non-woven fabric. The colorful fastness spunlaced non-woven fabric 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 colorful and non-fading spunlace nonwoven fabric with both the function of reinforcing ribs of the nonwoven fabric and the function of color display and a manufacturing 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 o...
