Three-in-one spunlaced composite non-woven fabric

Abstract

The invention relates to a three-in-one spunlaced composite non-woven fabric, belonging to the technical field of non-woven fabrics, wherein the non-woven fabric comprises a substrate layer, a hygroscopic layer and a hydrophilic layer, which are integrated in spunlace, wherein the hygroscopic layer is located between the substrate layer and the hydrophilic layer; the substrate layer comprises chemical short fibers or degradable short fibers; the hygroscopic layer comprises wood pulp short fibers; and the hydrophilic layer comprises spunbonded non-woven fabrics. The three-in-one spunlaced composite non-woven fabric has the advantages that the non-woven fabric has good softness, excellent contact feel and great water aggregation performance as the chemical short fibers or degradable short fibers are used as the substrate layer, not only has excellent strength but also has great water aggregation performance as the spunbonded non-woven fabrics are used as the hydrophilic layer, and can play a good high-hygroscopic effect as the wood pulp short fibers are used as the hygroscopic layer; both the hygroscopic layer and the hydrophilic layer are degradable to reflect the green environmental effect; and the overall structure is simple and inexpensive to meet the disposable requirement.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a three-in-one spunlace composite non-woven fabric, which is used in the medical industry to make protective clothing, clinical nursing pads, masks, wiping paper, and as industrial and household wiping materials. . Background technique [0002] Spunlace non-woven fabrics belong to the category of non-woven fabrics, and the industry is also called non-needle-punched non-woven fabrics. The spunlace process is to spray fine water onto one or more layers of fiber cotton nets to entangle the fibers to obtain a certain strength and strength. form a complete structure. The technological process is roughly: fiber metering and mixing, opening machine opening, carding machine carding into web, fiber web prewetting, hydroentangling, surface treatment, drying and coiling. Compared with common needle-punched non-woven fabrics, the physical properties of spunlace non-...
