What is the material of non-woven fabric?

Nonwoven fabric (English name: Non-woven fabric or non-woven fabric), also known as nonwoven fabric, consists of oriented or random fibers. It is called cloth because of its appearance and some properties.

Non-woven fabrics are moisture-proof, breathable, flexible, light, non-combustion-supporting, easy to decompose, non-toxic and non-irritating, rich in color, low in price and recyclable. For example, polypropylene (pp material) granules are used as raw materials, which are made by one-step continuous melting, spinning, laying and hot-pressing winding.

2. Features

Non-woven fabrics have no latitude and longitude lines, so it is very convenient to cut and sew, and it is light and easy to shape, which is very popular among handicraft lovers.

Because it is a kind of fabric formed without spinning and weaving, it is only formed by orienting or randomly arranging textile short fibers or filaments to form a network structure, and then strengthening it by mechanical, thermal bonding or chemical methods.

It is not woven by interweaving a yarn, but by directly bonding the fibers together through physical methods, so when you get the sticky scales in your clothes, you will find that you can't even draw out a thread. Nonwovens break through the traditional textile principle and have the characteristics of short technological process, fast production speed, high output, low cost, wide application and many sources of raw materials.

First, the use of non-woven fabrics.

Non-woven products are rich in color, bright, fashionable and environmentally friendly, widely used, elegant in appearance, diverse in pattern styles, light in weight, environmentally friendly and recyclable, and are internationally recognized as environmentally friendly products to protect the earth's ecology. Suitable for agricultural film, shoemaking, tanning, mattress, quilt, decoration, chemical industry, printing, automobile, building materials, furniture and other industries, as well as clothing interlining, medical and health disposable surgical gown, mask, hat, bed sheet, hotel disposable tablecloth, beauty, sauna and even modern gift bags, boutique bags, shopping bags, advertising bags and so on. Environmental protection products are widely used and economical.

Because it looks like a pearl, it is also called a pearl canvas.

Non-woven fabrics are made of chemical fibers and plant fibers on wet or dry paper machines with water or air as suspension medium. Although it is not woven cloth, it is called non-woven fabric. Non-woven fabric is a new generation of environmental protection materials, which has the advantages of good strength, air permeability and waterproof, environmental protection, flexibility, non-toxic and tasteless, low price and so on.

It is a new generation of environmental protection material, which has the characteristics of water repellent, breathable, flexible, non-combustion-supporting, non-toxic and non-irritating, rich in color and so on. If the material decomposes naturally outdoors, its longest life is only 90 days, and it will decompose within 8 years if it is placed indoors. It is non-toxic and harmless when burning, so it does not pollute the environment, so environmental protection comes from it.

(1) Non-woven fabrics for medical and health care: surgical gowns, protective clothing, disinfection kits, masks, diapers, household rags, rags, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary napkins.

(2) Non-woven fabrics for home decoration: wall covering, tablecloths, sheets, bedspreads, etc.

(3) Non-woven fabrics for clothing: lining, adhesive lining, wadding, setting cotton, various synthetic leather base fabrics, etc.

(4) industrial nonwovens; Base material, reinforcing material, polishing material, filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc. Roofing waterproofing membrane and asphalt tile.

(5) Non-woven fabrics for agriculture: crop protection cloth, nursery cloth, irrigation cloth, thermal insulation curtain, etc.

(6) Other non-woven fabrics: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette filter tip, tea bag in bag, shoe material, etc.

Second, the difference between non-woven fabrics and dust-free fabrics

Non-woven fabric, also known as non-woven fabric, is a new generation of environmental protection materials, which has the characteristics of water repellent, breathable, flexible, non-combustion-supporting, non-toxic and non-irritating, and rich colors. If the nonwoven fabric decomposes naturally outdoors, its longest service life is only 90 days; If it is decomposed indoors within 5 years, it is non-toxic and tasteless, without any residual substances, so it does not pollute the environment and is suitable for washing.

It directly uses polymer chips, short fibers or filaments to form a new fiber product with soft, breathable and planar structure through various web-forming methods and consolidation techniques. It has environmental protection performance that plastic products do not have, and its natural degradation time is much shorter than that of plastic bags. Therefore, non-woven bags made of non-woven fabrics are also recognized as the most economical and practical reusable shopping bags.

The dust-free cloth is made of 100% polyester fiber, with soft surface, easy to wipe sensitive surfaces, no fiber loss when rubbed, good water absorption and cleaning efficiency. The cleaning and packaging of products are completed in the ultra-clean workshop. The optional edge sealing of dust-free cloth generally includes: cold cutting, laser edge sealing and ultrasonic edge sealing.

Ultra-fine fiber dust-free cloth is generally sealed perfectly by laser and ultrasonic; Dust-free cloth, dust-free wiping cloth, superfine fiber dust-free cloth and superfine fiber wiping cloth are made of 100% continuous polyester double-layer fabric with soft surface, which can be used to wipe sensitive surfaces with low dust production, good water absorption and cleaning efficiency. Especially suitable for dust-free purification workshop.

The edges of dust-free cloth, dust-free wiping cloth, superfine fiber dust-free cloth and superfine fiber wiping cloth are sealed by the most advanced trimming machine, so that particles and thread ends will not be left after wiping, and the decontamination ability is strong.
