Non woven fabric knowledge

Non woven fabrics do not have warp and weft threads, making them very convenient to cut and sew. They are also lightweight and easy to shape, making them popular among handicraft enthusiasts.
Because it is a 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 or woven yarns one by one, but rather of fibers directly bonded together through physical methods. Therefore, when you take the adhesive lining in your clothes, you will find that it cannot extract thread ends 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, water spunlace method, and most non-woven fabrics on the market are produced using spunbond method)
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 referring 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 directly uses polymer chips, short fibers, or filaments to form fibers into a web through airflow or mechanical means, then undergoes water pricking, needling, or hot rolling reinforcement, and finally undergoes post-processing to form a non-woven fabric. A new type of fiber product with soft, breathable, and flat structure has the advantage of not producing fiber chips, being strong, durable, and silky soft. It is also a type of reinforcing material, and has a cotton feel. Compared with cotton fabrics, non-woven bags are easier to form and have a lower cost.
