Abstract

The invention relates to the technical field of non-woven fabrics and particularly relates to a flexible non-woven fabric and a preparation method thereof. The flexible non-woven fabric is prepared from the following raw materials in parts by weight: 30-35 parts of polypropylene, 20-25 parts of regenerated polypropylene, 30-35 parts of calcium carbonate filling master batch, 10-15 parts of an elastomer, 0.2-0.25 part of flexile filling master batch and 1-3 parts of a lubricant. The high-softness environment-friendly flexible non-woven fabric has good softness, no toxin and no irritation, is safe and environment-friendly and has natural and clear lines; and the flexible non-woven fabric also has the advantages of bacterium resistance, corrosion resistance, mildew prevention and the like and has an excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a flexible non-woven fabric and a preparation method thereof. Background technique [0002] With the development of science and technology and the progress of the non-woven fabric industry, the variety of non-woven fabrics has continued to increase, and its application range has expanded from people's daily life to industry, agriculture, transportation, military, health and many other fields. At the same time, since most non-woven fabrics do not meet the requirements of environmental protection and low carbon, and their softness is poor, their use in life, industry and other fields is limited. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a flexible non-woven fabric, which has good softness, non-toxic and non-irritating, safe and environmentally friendly, a...
