Abstract

The invention provides a modified cellulose spunlace non-woven fabric and a preparation method thereof, and belongs to the technical field of spunlace non-woven fabrics. The modified cellulose spunlace non-woven fabric is prepared from the following raw materials of modified cellulose, polypropylene, tetrabutyl titanate and deionized water. The modified cellulose has a structure shown in the specification, wherein n is equal to 100 to 300. The prepared modified cellulose spunlace non-woven fabric not only has good antibacterial and bacteriostatic performance, but also has certain formaldehyde purification capacity, good skin-friendly performance and good mechanical performance; after spunlace reinforcement, fibers in the non-woven fabric are displaced, interspersed, entangled and cohered to form countless flexible entanglement points, so that the non-woven fabric is reinforced, and the high-performance spunlace non-woven fabric is obtained.

Description

technical field [0001] The invention relates to the technical field of spunlace nonwoven fabrics, in particular to a modified cellulose spunlace nonwoven fabric and a preparation method thereof. Background technique [0002] Cellulose spunlace non-woven fabric is made of cellulose through spunlace process. Since the cellulose comes from plants and no chemical binder is added during the processing, the non-woven fabric is soft, hydrophilic, Skin-adhesive properties, widely used in fabric base fabrics, wet wipes, medical dressings and other occasions. [0003] 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. To put it simply: it is not interwoven and knitted together by one yarn, but the fibers are directly bonded together by physical or chemical methods, so when you get the glue in your clothes When you weigh it, you will find that you can't pull out the threa...
