Main inspection items of non-woven fabrics

Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, and price Low-cost, recyclable and other characteristics.


1. Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, Sanitary pads, and disposable sanitary cloths, etc.


2. Non-woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.


3. Non-woven fabrics for clothing: lining, fusible interlining, wadding, shaped cotton, various synthetic leather base fabrics, etc.


4. Industrial non-woven fabrics: base materials, reinforcement materials, polishing materials, filter materials, insulating materials, cement packaging bags, geotextiles, covering cloths, etc. for roofing waterproof membranes and asphalt shingles.


5. Agricultural non-woven fabrics: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.


6. Other non-woven fabrics: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, shoe materials, etc.
