Abstract

The invention provides a double-layer water-adsorption and moisture-transfer non-woven fabric and a preparation method thereof. The double-layer water-adsorption and moisture-transfer non-woven fabric comprises an inner layer with moisture adsorption performance and an outer layer, wherein the inner layer with moisture adsorption performance is compounded in a hot-rolling compounding method and mainly comprises the following components in parts by weight: 10-50 parts of natural vegetable fiber, 45-80 parts of polypropylene resin granules, 1-6 parts of compatilizers, 0.5-3 parts of antioxidants and 2-10 parts of toughening filler; the fiber size of the outer layer is 0.6-0.8 denier, and a polypropylene resin fine-denier short-fiber non-woven fabric is prepared from the polypropylene resin granules. The double-layer water-adsorption and moisture-transfer non-woven fabric has the advantages of light weight, good toughness, degradability, high water-adsorption rate and good moisture transfer.

Description

technical field [0001] The invention relates to a nonwoven fabric and a preparation method thereof, in particular to a double-layer water-absorbing and moisture-conducting nonwoven fabric made of natural fiber / polypropylene composite material and a preparation method thereof. Background technique [0002] Natural fiber is the most abundant natural polymer material in nature. The total amount of cellulose (existing in the form of natural plant fiber) grown in nature every year reaches as many as 100 billion tons, far exceeding the total reserves of existing oil on the earth. Natural fiber is an extremely important resource. Today, when natural resources are increasingly scarce, making full use of the potential of natural fiber resources, exerting its unique functions and characteristics, and developing new application fields is an attractive research hotspot today. Natural fibers can be utilized in a variety of ways, such as their fibrils, their derivatives, or their graft co...
