Non-woven fabric (non-woven fabric, non-woven cloth), is a kind of cloth produced by processing various fiber raw materials with needle rolling machinery or carding machinery, and forming or bonding with high pressure.
Non-woven fabrics are also divided into old and new technologies or in a broad and narrow sense. Synthetic fleece made from old technology. The new technology has resulted in common environmental protection shopping bags, N95 masks, and many curtain rag products in the ten-yuan store. The texture often has even and neat embossing points. In a broad sense, non-woven fabrics include all cloth-like objects that are not woven with threads, even paper; in a narrow sense, non-woven fabrics refer to finished products with neatly imprinted parts.
Non-woven textile bags can be made of any fiber, and if there is a textile recycling plant nearby, these recycled fibers can be transported for further processing at low cost.
Fibers can be shredded cloth, man-made fibers or synthetic fibers (glue, resin, etc.), and the fiber raw materials of non-woven fabrics often contain polypropylene (Polypropylene), abbreviated as PP. Or polyethylene (polyethylene), referred to as PE.
Unlike woven fabrics, non-woven fabrics are woven by non woven machine warp and weft, and the production of non-woven fabrics varies with different construction methods. Intertwined with each other, each entanglement will make the cotton body more and more solid.
Whats the nonwoven fabric advantage?
Advantages of non-woven fabrics: Non-woven fabrics are non-woven fabrics, also known as non-woven fabrics. A sheet, web or batt made of oriented or randomly arranged pure natural cotton and linen fibers bonded to each other by friction, cohesion or bonding or a combination of these methods. The non-woven material has a unique hollow structure, which is convenient for ventilation, formaldehyde-free, waterproof and moisture-proof, and can effectively adjust the indoor air humidity. It is rich, recyclable, and feels friendly and natural. Its fiber filaments have strong weaving tension. When the whole non-woven paper is completely burned, only carbon dioxide and water are generated, and no toxic gas is produced. It is a new type of environmentally friendly wallpaper that can be safely attached to various rooms in the home.
The main uses of non-woven fabrics:
Medical field: Non-woven fabrics are mainly used in surgical gowns, protective clothing, masks and diapers in this field.
Home decor: bedspreads and sheets and tablecloths, etc.
Apparel surface accessories: Adhesive lining and lining and shaping cotton, etc.
Industrial aspects: industrial cement packaging bags, and some industrial materials (filters, insulating materials).
Agricultural fields: such as some seedling raising cloths, irrigation cloths and thermal insulation curtains, etc.
Whats the test standard for nonwoven fabric?
Non-woven fabric is an eco-friendly product that is versatile and economical. Because it looks like pearls, it is also called pearl canvas. What are the inspection criteria when purchasing it? Here is my compilation:
1. There is no obvious color difference between the actual color of the non-woven fabric and the color of the engineering sample. If there is chromatic aberration, it can be the cause of the camera or the quality of the product.
2. In terms of appearance, the surface should have uniform color, good flatness and thickness, and no obvious defects such as cloud spots, glue spots, deformation, wrinkling, and damage.
3. Dimensions. The gram weight tolerance standard of non-woven fabrics is ±2.5%, and the width tolerance is ±0.5cm. Read the product description carefully before purchasing.
4. There should be no delamination and fluff on the upper structure of the non-woven fabric. The tensile breaking force of the non-woven fabric is generally 75g/100g≥30N, and the penetration force is generally 75g≥1.0J and 100g≥1.5J. .
5. Packaging. Generally speaking, the packaging of non-woven fabrics is 350-400Y/roll, which is packaged in transparent PP plastic bags, and it is also necessary to observe the factory certificate of complete specifications.
The above are the inspection standards for non-woven fabrics, which can be used as a reference when purchasing. It decomposes naturally outdoors and has a lifespan of only 90 days. Decompose indoors within 8 years. It is non-toxic and harmless when burning, and does not pollute the environment. Therefore, environmental protection comes from this.
