Title:
DEGRADABLE COMPOSITE NON-WOVEN FABRIC AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/000642
Kind Code:
A1
Abstract:
A degradable composite non-woven fabric, which is a layered structure that comprises an upper surface layer, an intermediate fiber layer and a lower surface layer in sequence. The upper and lower surface layers of the degradable composite non-woven fabric are mainly composed of degradable melt-blown fibers. The intermediate fiber layer is mainly composed of degradable water-absorbing fibers, wherein the weight of fibers of the intermediate layer accounts for more than 65% of the total weight of the composite non-woven fabric, and there are fiber interwoven regions between the upper and lower surface layers and adjacent layers of the intermediate fiber layer. Compared to traditional methods of incineration and burning for wiping non-woven waste, a degradable wiping non-woven fabric may be disposed of by landfill and degraded in soil, and carbon dioxide which is produced directly enters soil organic matter or is absorbed by plants without being discharged into the atmosphere and causing a greenhouse effect.
