[0097] A preparation method for degradable spunlace nonwoven material for nursing, comprising the following steps:
[0098] 1) The wood pulp is sent into a crushing tank to fully disintegrate to make a wood pulp mixture with a concentration of 3-6 wt%.
[0099] 2) Send the degradable ultra-short fiber into the discharge tank to complete the fiber dispersion, and make an ultra-short fiber slurry with a concentration of 0.1-1wt%, and then mix it with a wood pulp mixture to make a slurry with a concentration of 1-3wt%. Fiber mixing slurry; remove impurities and fiber clusters, so that the fibers are evenly distributed in the slurry.
[0100] 3) After stirring and diluting the fiber mixed slurry, it is sent to the inclined wire forming machine through the slurry pump, and dehydrated on the wet former to make a mixed fiber web and place it on the wet supporting screen curtain.
[0101] 4) Peel off the mixed fiber web from the wet-laid tray and transfer it to the hydroentangled tra...
Embodiment 1
[0110] Such as Figure 1-2 As shown, a degradable spunlace non-woven material 1 for nursing care, the mass per unit area is 80g / m 2 , by intertwining 50% virgin wood pulp fibers and 50% viscose ultra-short fibers; the length of viscose ultra-short fibers is 10mm. A dry care agent is attached to the surface of the wood pulp fiber and the viscose ultra-short fiber; 10-mesh square through-holes 4 are distributed on the surface of the spunlace nonwoven material and run through the front and back. The through holes separate the fibers in the spunlace nonwoven material into several parallel longitudinal fiber bundles 2 and several parallel transverse fiber bundles 3; the thickness of the longitudinal fiber bundles is greater than that of the transverse fiber bundles, and the longitudinal The fiber bundles form several parallel fiber bundle convex strips on the surface of the spunlace nonwoven material.

Embodiment 2
[0122] A degradable spunlace non-woven material for nursing care, with a mass per unit area of 50g / m 2 , is formed by intertwining 30% virgin wood pulp fibers and 70% Tencel ultra-short fibers; the length of Tencel ultra-short fibers is 5mm. A dry care agent is attached to the surface of the wood pulp fiber and tencel ultra-short fiber; the surface of the spunlace nonwoven material is distributed with 8-mesh square through holes that run through the front and back of the spunlace nonwoven material. The through holes separate the fibers in the spunlace nonwoven material into several parallel longitudinal fiber bundles and several parallel transverse fiber bundles; the thickness of the longitudinal fiber bundles is greater than that of the transverse fiber bundles, and the longitudinal fiber bundles with high thickness The fiber bundles form several parallel fiber bundle convex strips on the surface of the spunlace nonwoven material.
[0123] Contain surfactant, emollient, an...
