Abstract

The invention relates to an antibacterial healthcare spunlaced fabric, in particular to a preparation method of a melt-blown spunlaced composite non-woven base fabric. The raw material is polypropylene (PP) slices (Yueyang, Hunan), and the melt index is 320-1600 g / min; the product weight is 10-100 g / m<2>, and the lateral mass per unit area CV value is smaller than 5%. The melt-blown spunlaced composite non-woven base fabric is prepared from the raw material through a method including the steps that firstly, a melt-blown fiber web is processed with the polypropylene slices; secondly, the melt-blown fiber web is reinforced through a spunlace machine to form the melt-blown spunlaced composite non-woven base fabric. The developed melt-blown spunlaced composite non-woven base fabric has variousunique functions and is well received by people; for example, gauze made of polypropylene has the advantages of not adhering to wounds and having no toxicity, and thus the melt-blown spunlaced composite non-woven base fabric developed with polypropylene can be widely used in the medical treatment cause.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a melt-blown spunlace composite nonwoven fabric formed by processing a fiber web made of polypropylene fibers and then adopting a spunlace processing method, as well as its preparation method and application. Background technique [0002] The thermal conductivity of polypropylene is the lowest among all fibers, generally 2.1~4.2×10 -4 cal / cm.degree.second. Better than wool for insulation, polypropylene (PP) is the Chinese trade name for isotactic polypropylene fibers. [0003] The texture of polypropylene fiber is very light, the density is only 0.91g / cm 3 , is currently the lightest fiber among all synthetic fibers. Polypropylene has high strength and good chemical corrosion resistance, but polypropylene has poor heat resistance, light resistance and dyeability. [0004] The fiber web is sprayed with multiple strands of fine water jets generated by high pressure, commonly known as "h...
