What is non-woven fabric?
Non-woven fabric is what we call non-woven fabric. This kind of fabric does not need to be spun and weaved. The process of arranging its short fibers or filaments randomly or directionally to form a network structure is then made into cloth through reinforcement and other processes. The process and production cycle of the non-woven fabric production process are short, so the cost is high. Naturally, it also dropped.
Main uses of non-woven fabrics:
Medical field: None Woven fabrics are mainly used in this field for surgical gowns, protective clothing, masks and diapers.
Home decoration: bedspreads and sheets, tablecloths, etc.
Work clothing accessories: adhesive lining and lining, styling cotton, etc.
Industrial aspects: industrial cement packaging bags, and some industrial materials (filtration, insulation materials).
Agricultural field: such as some seedling-raising cloths, irrigation cloths and thermal insulation curtains.
Advantages of non-woven fabrics:
1. The raw material of non-woven fabric is polypropylene resin. Its specific gravity is 0.9, which is only 60% of cotton. The cloth is loose and light.
2. Non-woven fabric is non-toxic, odorless and does not contain other chemical ingredients, so the fabric will not harm the skin. Cause irritation.
3. It also has antibacterial and insect-proof properties.
4. The fabric fibers have a porous structure, so they have better air permeability, and the fabric surface is also Relatively dry.
Disadvantages of non-woven fabrics:
The strength and wear resistance of the fabric are poor. Some types of non-woven fabrics cannot be washed, and the fibers may crack at right angles.
Type of non-woven fabric:
1. Spunlace non-woven fabric: It is made of non-woven fabric after spunlace process. The strength of the fabric will be higher than It was much bigger before.
2. Heat-sealing non-woven fabric: This type of fabric is Made through heating and melting processes.
3. Air-laid non-woven fabrics: Mainly using air-laid technology to form fabrics.
4. Wet-laid non-woven fabric: it is the fiber Made by reinforcing it in the wet state.
