Abstract

The invention relates to a dust-proof composite non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabrics and its preparation. The dust-proof composite non-woven fabric comprises a non-woven fabric composite layer and a nano-coating uniformly sprayed on the surface of the non-woven fabric composite layer, and the non-woven fabric composite layer consists of a first non-woven fabric layer, a second non-woven fabric layer The cloth layer and the third non-woven fabric layer are compounded sequentially. The dust-proof composite non-woven fabric is made of different non-woven fabrics by hot-melt spinning, and then hot-rolled and composited, and then the nano-coating is vacuum sprayed on the non-woven composite layer to obtain the finished product. The invention has the advantages of good dustproof effect, high strength and simple preparation process.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric and its preparation, in particular to a dustproof composite nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicra...
