Abstract

The invention discloses a polypropylene non-woven fabric and a preparation method thereof. The polypropylene non-woven fabric is prepared by taking polypropylene resin prepared from polypropylene non-woven fabric recycle material as the raw material and adding a molecular weight regulator, wherein the quantity of the molecular weight regulator is 0.1%-0.3% of the gross of the polypropylene resin. The polypropylene non-woven fabric is pliable, tough and light and has good flexibility, breathability and small residual deformation. The invention takes good advantages of the recycle material of polypropylene non-woven fabric, thereby saving resources and protecting the environment; and the prepared polypropylene non-woven fabric is a recyclable and environmentally friendly product which not only fits the development thougtht of circular economy, but also has low production cost and excellent product performance.

Description

technical field [0001] The invention relates to a nonwoven fabric, in particular to a polypropylene nonwoven fabric based on recycled polypropylene nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric (also known as non-woven fabric, English: Non woven) is a green product, tough and durable, beautiful in shape, and good in air permeability. Polypropylene (PP) non-woven fabric has the advantages of low cost, light weight, corrosion resistance and good chemical stability. Napkins, tablecloths, wall coverings, carpets, clothing linings, etc. made of polypropylene (PP) non-woven fabrics have penetrated into people's normal lives. Polypropylene (PP) non-woven filter materials, insulation materials, civil construction materials, etc. have become indispensable engineering materials in many industrial sectors. In addition, the application of non-woven fabrics in agricultural production is also expanding, for mulch, greenhouses, etc. Non...
