Shoe material and filtering special-purpose hydrophilic non-woven fabric and manufacturing method thereof

Abstract

The invention discloses a shoe material and filtering special-purpose hydrophilic non-woven fabric and a manufacturing method thereof, and belongs to the field of non-woven fabric materials. The non-woven fabric includes, by mass, 75-98% of polypropylene fibers and 2-25% of an additive, wherein the additive is blank master batch. The non-woven fabric has excellent elasticity, hydrophily and absorbability, can be used in vamps and shoe inner layers, has a good pollutant removal effect, and provides a new direction for municipal sewage treatment.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a special hydrophilic non-woven fabric for shoe materials and filtration and a manufacturing method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low price, recyclable and reusable, Duoliru adopts polypropylene as raw material, and it is produced in one continuous step through high-temperature melting, spinning, general netting, and hot-pressing coiling. [0003] In recent years, my country's non-woven fabric industry has developed faster and faster. At present, the total output has ranked second in the world. The application fields of non-woven fabrics are very wide, such as our common masks, wet wipes and diapers, new fields such as medical textiles, protective flame-retardant textiles and some special composite materials, ...

Problems solved by technology

[0004] In recent years, my country's sewage treatment business has flourished, sewage treatment facilities have been constructed at a high speed, and sewage treatment capacity has been continuously improved. As the mainstream filtration method, mud membrane bioreactors are mainly divided into fixed packing and suspended packing. Suspended packing Mainly polyethylene and polypropylene, including porous foam fillers, Kaldnes fillers, spherical or columnar suspension fillers, etc., there are problems such as unreasonable structure and poor hydrophilicity of the filler materials, resulting in low filtering effect and difficult to meet the existing requirements. need

[0005] At present, non-woven fabrics are used as media to improve the filtering effect. For example, the patent No. CN103058357A discloses a method for making biological fillers for treating refractory wastewater, using non-woven fabrics as biological fillers to improve the ability to degrade wastewater; Patent No. CN103085374B discloses a melt-blown activated carbon non-woven fabric, which uses activated carbon to be mixed into the non-woven fabric to improve adsorption and filtration capabilities. However, the above-mentioned and existing technologies have insufficient hydrophilicity of biological fillers and poor adsorption capacity. problems, failing to provide satisfactory sewage and wastewater treatment effects
