Without warp and weft threads, cutting and sewing are very convenient, and it is lightweight and easy to shape, which is deeply loved by handicraft enthusiasts. It is a type of fabric that does not require spinning or weaving, but is formed by orienting or randomly arranging textile short fibers or long fibers to form a web structure, and then reinforcing it using mechanical, thermal bonding, or chemical methods. It is not made up of interwoven and woven yarns, but rather fibers that are directly bonded together through physical methods. Therefore, when you get the adhesive scale in your clothes, you will find that it is impossible to pull out each thread end.
The relationship between non woven fabric and spunbond fabric
Spunbond fabric and non-woven fabric have a subordinate relationship. There are many production processes for the manufacture of non-woven fabrics, among which spunbond method is one of them. Spunbond non-woven fabrics (including spunbond method, meltblown method, hot rolling method, water jet method, most of which are produced by spunbond method on the market) are spunbond non-woven fabrics.
Classification of non woven fabrics
Non woven fabrics can be made of polyester, polypropylene, nylon, spandex, acrylic, etc., depending on their composition; Different ingredients will have completely different non-woven fabric styles. And spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; And the styles of these two fabrics are very similar, which can only be distinguished through high-temperature testing. The composition and structure of non-woven fabric products are rich in color, bright and lively, fashionable and environmentally friendly, widely used, beautiful and generous, with diverse patterns and styles. They are lightweight, environmentally friendly, and recyclable, and are internationally recognized as environmentally friendly products that protect the earth’s ecology. Suitable for industries such as agricultural film, shoemaking, leather making, mattresses, mother and child quilts, decoration, chemical, printing, automotive, building materials, furniture, as well as clothing lining, disposable surgical gowns for medical and health care, masks, hats, bed sheets, disposable hotel tablecloths, beauty, sauna, and even modern gift bags, boutique bags, shopping bags, advertising bags, etc. Environmentally friendly products, widely used and cost-effective.
Characteristics of non-woven fabric
Non woven fabric is a new generation of environmentally friendly materials, which has the advantages of good strength, breathability and waterproofing, environmental friendliness, flexibility, non toxicity and odorlessness, and low price. It is a new generation of environmentally friendly material with characteristics such as water repellency, breathability, flexibility, non combustible, non-toxic and non irritating, and rich colors. If this material is placed outdoors and naturally decomposed, its longest lifespan is only 90 days. If placed indoors, it decomposes within 8 years. When burned, it is non-toxic, odorless, and has no residual substances, thus not polluting the environment. Therefore, environmental protection comes from this.
Material characteristics
Advantages:
1. Lightweight: Made mainly from polypropylene resin, with a specific gravity of only 0.9, only three fifths of cotton, it has fluffiness and a good hand feel.
2. Soft: Composed of fine fibers (2-3D), it is formed by light spot hot melt bonding. The finished product has moderate softness and a comfortable feeling.
3. Water repellent and breathable: Polypropylene slices do not absorb water and have zero moisture content. The finished product has good water repellent properties and is composed of 100% fibers, which are porous and breathable, making it easy to keep the fabric dry and easy to wash.
4. Non toxic and non irritating: The product is produced using FDA food grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, odorless, and does not irritate the skin.
5. Antibacterial and chemical resistant agents: Polypropylene is a chemically inert substance that is not insect infested and can isolate the erosion of bacteria and insects in liquids; Antibacterial, alkaline corrosion, and the strength of the finished product is not affected by erosion.
6. Antibacterial properties. The product is water-resistant, does not mold, and can isolate the erosion of bacteria and insects in the liquid, without mold damage.
7. Good physical properties. Made by spinning polypropylene and directly laying it into a mesh through thermal bonding, the product has better strength than ordinary short fiber products, with no directional strength and similar longitudinal and transverse strength.
8. In terms of environmental protection, the majority of non-woven fabrics currently used are made of polypropylene, while plastic bags are made of polyethylene. Although the two substances have similar names, their chemical structures are vastly different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so plastic bags need 300 years to decompose completely;
However, the chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can effectively degrade and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and their environmental pollution after disposal is only 10% of that of plastic bags.
Disadvantages:
1) Compared with textile fabrics, it has poor strength and durability.
2) It cannot be cleaned like other fabrics.
3) The fibers are arranged in a certain direction, so it is easy to crack from the right angle direction, etc. Therefore, recent improvements in production methods have mainly focused on preventing fragmentation.
