Embodiment Construction

[0026] A cotton-containing non-woven fabric used for sanitary napkins of the present invention comprises a quick-drying skin-friendly layer and a drainage fiber layer, the quick-drying skin-friendly layer is a porous cotton-containing fiber water-repellent layer, and the drainage fiber layer is a drainage fiber layer. Water spunbonded fiber layer, the drainage fiber layer is provided with a plurality of drainage and dry protrusions, the quick-drying skin-friendly layer and the drainage fiber layer are combined by spunlace, and the quick-drying skin-friendly layer is uniform There are 10-40 mesh water permeable holes densely distributed, and the drainage dry projections on the drainage fiber layer are in a one-to-one correspondence with the position of the water permeable holes. The fast-drying skin-friendly layer is composed of the following components by mass fraction: cotton 85%-100% fiber, 0%-15% hot-melt fiber; the mass density of the quick-drying skin-friendly layer is 20-...

Abstract

The invention discloses a cotton-containing non-woven fabric for a sanitary towel and a preparation method thereof. A hydrophilic drainage spunbonded nonwoven as a drainage fiber layer and a water-repellent punched cotton-containing fabric as a quickly dried skin-friendly layer are laminated to form a composite cloth material. Hydroentanglement is performed on the composite material and the composite material is dried, so that the cloth material integrates properties of high strength, high moisture absorption, high drainage and high permeability, is unlikely to deform, durable and dry and comfortable and good in skin-friendliness, and market promotion and application are facilitated.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of textile products, in particular to the technical field of a cotton-containing nonwoven fabric used for sanitary napkins and a preparation method thereof. [0003] 【Background technique】 [0004] Spunbond technology is a new technology of non-woven fabrics gradually developed in the late 1950s, and it is the most successful example of the combination of chemical fiber technology and non-woven technology. The traditional ways to reinforce the spun fiber web mainly include acupuncture method and hot rolling bonding method. The nonwoven fabric produced has the characteristics of high strength and variety, but the hand feeling, permeability and fiber uniformity are poor. Uses are not extended. Usually 200g / m 2 The above spun fiber webs reinforced by acupuncture are mainly used for geotextiles and roof waterproof materials; 60-200 g / m 2 Non-woven fabrics reinforced by hot rolling of spun fiber webs a...
