The main raw material for nonwovens is polypropylene (polypropylene), but it is not the only raw material. Polyester (polyester), polyamide fibres, polyacrylonitrile fibres and viscose fibres can be used to produce nonwovens. This is actually a misunderstanding of nonwovens. Like the fabrics we usually wear, nonwovens are also available in chemical fibre and natural fibre, only that chemical fibre nonwovens are more common.
Polypropylene long fibres can be divided into ordinary long fibres and fine denier long fibres (monofilament fibre size ≤ 2.2 dtex), which can be used for the production of garments and decorative and some industrial filament products. Polypropylene fine denier long fibres have good lustre, a soft hand, good drapability and low density, and are suitable for the knitting industry. When interwoven with cotton, viscose silk, silk and spandex to form cotton-covered C, silk-covered C and other products, they are ideal for the production of high-grade sportswear and T-shirts.
Uses of non-woven fabrics
(1) Non-woven fabrics for medical and hygiene use: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civil wipes, wiping cloths, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable hygiene cloths, etc.
(2) Non-woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.
(3) Nonwoven fabrics for garments: lining, bonding lining, flocking, shaping cotton, various synthetic leather backings, etc.
(4) Nonwoven fabrics for industrial use; filter materials, insulation materials, cement packaging bags, geotextiles, covering fabrics, etc.
(5) Nonwoven fabrics for agriculture: crop protection cloth, rice-raising cloth, irrigation cloth, insulation curtain, etc.
(6) Other non-woven fabrics: space wool, heat insulation and sound insulation materials, oil-absorbing felt, cigarette filters, bagged tea bags, etc.
With no warp or weft threads, nonwovens are very easy to cut and sew, and are light and easy to shape, making them popular with craft enthusiasts. This is because it is a fabric that does not need to be spun and woven, but is simply a structure of textile staple fibres or filaments arranged in a directional or random way to form a fibre web, which is then mechanically, thermally or chemically reinforced.
