The Difference Between Polyester And Non-woven Fabric?
The difference between polyester and non-woven fabrics: different preparation methods, different characteristics, and different uses.
1. Different preparation methods
Polyester: a fiber-forming polymer made from polyterephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions ——Polyethylene terephthalate (PET), a fiber made by spinning and post-processing.
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric.
2. Different features
Polyester: high toughness. The short fiber strength is 2.6~5.7cN/dtex, and the high-strength fiber is 5.6~8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber.
The non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light in weight and easy to shape, which is deeply loved by craft lovers. It has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials.
3. Different uses
Polyester is widely used in the manufacture of clothing and industrial products. Due to its permanent flame retardancy, flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interior decoration, and vehicle interior decoration, it also plays a lot of roles in the field of protective clothing.
Non-woven fabric: suitable for agricultural film, shoemaking, tanning, mattress, picture-behind quilt, decoration, chemical, printing, automobile, building materials, furniture and other industries, as well as clothing interlining, medical and health disposable surgical gowns, masks, caps , Bed sheets, hotel disposable tablecloths, beauty, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags, etc.
