Non woven fabrics do not have warp and weft threads, making cutting and sewing very convenient. They are also lightweight and easy to shape, making them popular among handicraft enthusiasts.
Because it is a type of fabric formed without the need for spinning and weaving, it simply orients or randomly arranges textile short fibers or filaments to form a fiber network structure, which is then reinforced by mechanical, thermal adhesive, or chemical methods.
It is not made up of interwoven and woven yarns one by one, but rather by directly bonding fibers together through physical methods. Therefore, when you take the adhesive lining from the clothes, you will find that it is impossible to pull out the threads one by one. Non woven fabrics break through traditional textile principles and have the characteristics of short process flow, fast production rate, high yield, low cost, wide use, and multiple sources of raw materials.
The relationship between non-woven fabric and spunbond fabric
Spunbonded fabric and non-woven fabric are in a subordinate relationship. There are many production processes for the production of non-woven fabrics, and spunbond method is one of them (including spunbond method, melt blown method, hot rolling method, and water jet method, most of which are produced by spunbond method on the market)
Non woven fabrics include polyester, polypropylene, nylon, spandex, acrylic, etc. based on their composition; Different ingredients will have completely different styles of non-woven fabrics. And spunbond fabric usually refers to polyester spunbond or polypropylene spunbond; And the styles of these two fabrics are very similar, which can only be distinguished through high-temperature testing.
Non woven fabric is a type of non-woven fabric that is formed by directly using high polymer chips, short fibers, or long fibers to form a web through airflow or mechanical means. The fibers are then reinforced by water needling, needle punching, or hot rolling, and finally processed to form a non-woven fabric. A new type of fiber product with soft, breathable, and flat structure has the advantages of not producing fiber chips, being strong, durable, and silky soft. It is also a type of reinforcing material, and has a cotton like feeling. Compared with cotton fabrics, non-woven bags are easy to form and have a lower cost.
