1. Infiltration amount: It can be seen from the above table that the infiltration amount of the material in Example 1 is 3.34% higher than that of the material in Comparative Example 1.
[0067] The reason is that although the material in Example 1 is greatly affected by the proportion of hydrophobic fibers on the front side, which affects the wetting speed of the material by the test solution, as the wetting of the material by the test solution is completed, the gradual hydrophilicity of the material in Example 1 itself The structure makes it easier for the test fluid to move inside the material.
[0068] 2. Rewetting amount: It can be seen from the above table that the rewetting amount of the material in Example 1 is 68.5% higher than that of the material in Comparative Example 1, which shows that the technical solution of the present invention has particularly obvious advantages in the material rewetting amount performance. Its reason is: because the proportion of hydrophobi...

Abstract
The invention relates to the field of non-woven materials, and discloses a high-softness dry degradable non-woven material and a preparation method thereof.The high-softness dry degradable non-woven material is a sheet-shaped flexible fiber aggregate formed by mutually entangling biomass hydrophobic fibers and hydrophilic fibers, and the two surfaces of the material are a hydrophobic surface and a hydrophilic surface respectively; the ratio of the distribution area of the hydrophobic fibers on the hydrophobic surface to the total area of the hydrophobic surface is greater than or equal to 80%, and the distribution area is gradually reduced in the vertical direction from the hydrophobic surface to the hydrophilic surface; the ratio of the distribution area of the hydrophilic fibers on the hydrophilic surface to the total area of the hydrophilic surface is larger than or equal to 80%, and the distribution area of the hydrophilic fibers gradually increases in the vertical direction from the hydrophobic surface to the hydrophilic surface. The high-softness dry and comfortable degradable non-woven material can be naturally degraded, is good in dry and comfortable performance and high in softness, and is suitable for being used as a surface layer material of personal hygiene nursing materials.
Description
technical field [0001] The invention relates to the field of nonwoven materials, in particular to a highly soft and dry degradable nonwoven material and a preparation method thereof. Background technique [0002] With the improvement of living standards and the strengthening of health awareness, consumers' demand for comfort, safety and health in the choice of hygiene products continues to increase. In the process of choosing hygiene products, consumers prefer personal hygiene care products with a dry surface because they are more comfortable during use. [0003] Patent CN201620020627.8 discloses a unidirectional moisture-conducting non-woven fabric, including a hydrophilic spunbond layer on the outer surface and a hydrophobic spunbond layer on the inner surface, the hydrophilic spunbond layer and the hydrophobic spunbond The cloth layers are superimposed on each other by hot pressing, wherein the material of the hydrophilic spunbonded cloth layer is polypropylene grafted a...
