The classification standard of non-woven fabric grades is based on the types, quality grades, application fields, and performance characteristics of non-woven fabrics. To distinguish, non-woven fabrics can be divided into spunlace non-woven fabrics, heat-bonded non-woven fabrics, agricultural non-woven fabrics, spunbond non-woven fabrics, melt-blown non-woven fabrics, needle-punched non-woven fabrics, hydrophilic non-woven fabrics and Medical non-woven fabrics and other different categories!
Non-woven grade classification standard:
Meltblown non-woven fabric is an important material used in masks, filters, wiping products, and composite fabrics. It is a non-manufacturing non-woven fabric with polypropylene as the main raw material. Its filtration efficiency is one of the factors affecting product price. Meltblown level and filtration efficiency are mutual. High-grade non-woven grades will bring good filtration efficiency. Poor grade nonwovens bring poor filtration efficiency. At present, the filter grades of meltblown non-woven fabrics are N, BFE, VFE, KN, and FFP.
Now non-woven bags are made of more confusing materials. Non-woven materials are divided into several grades and grades according to their quality and quality. The non-woven bags on the market are mainly divided into two types of non-woven fabrics: brand-new non-woven fabrics. Cloth, recycled non-woven fabrics. The non-woven material of the new material is made of new PP particles. The non-woven bag produced by this non-woven material is bright in color, thick in hand and strong in tension.
Recycled non-woven fabrics are non-woven fabrics mixed with a certain proportion of recycled materials or powders and calcium carbonate powder. Non-woven fabrics, discarded polypropylene plastic bags, non-woven bags, and woven plastic bags can all be used as the primary raw materials of non-woven fabrics, which can be cleaned, melted and granulated for the production of recycled non-woven fabrics. Due to the incorporation of recycled materials, the non-woven bag made of this non-woven fabric is dull in color, thin in hand and poor in tension.
The difference between the new non-woven fabric and the recycled non-woven fabric is that the non-woven fabric of the same gram weight feels thicker and feels like a non-woven fabric of the same thickness. The new non-woven fabric is lighter in weight and has a greater pulling force.
In the textile industry, non-woven fabrics will be graded according to the quality performance, specifications and uses of non-woven products, and the different quality grades of various non-woven fabrics will be determined according to the grades. The higher the non-woven fabric grade, generally means no The higher the quality of the fabric, the more expensive it will be!
