What is recycled polyester yarn
Recycled polyester fiber refers to the use of polyester fabric, waste polyester bottle flakes, spinning waste silk, bubble material, pulp block as raw materials, waste bottle flakes are crushed and washed, the mixture of various materials is dried, melt extruded, spun Silk, winding, bundling, drafting, crimping (at the same time according to customer needs to add different oils during crimping), relaxation heat setting, after cutting to form polyester fibers of different lengths.
The length is generally 32 to 102mm, and the fineness has many specifications of 1.5D-20D, which is the full use of renewable resources. It has a broad market because of its low cost and good performance. Recycled polyester staple fiber has many different varieties, such as ordinary fiber , Hollow fiber, triangle wire, flame-retardant fiber, etc., are now generally used in furniture, toy filler industry, bedding, apparel industry, acupuncture cotton industry, stitch-bonded fabric industry.
What is polyester yarn
Variety of polyester fiber fabrics There are many types of polyester fiber fabrics. In addition to woven pure polyester fabrics, there are many products that are blended or interwoven with various textile fibers to make up for the deficiencies of pure polyester fabrics and exert better performance. . At present, polyester fabrics are developing in the direction of synthetic fibers such as wool, silk, linen, and buckskin. 1. Polyester simulation silk fabric is a polyester fabric with a silk appearance style woven from polyester filaments or short fiber yarns with round and irregular cross-sections. It has the advantages of no ironing and is popular among consumers. Common varieties are: polyester silk, polyester silk crepe, polyester silk satin, polyester georgette, polyester interwoven silk, etc. These varieties have the elegant drape of silk fabrics, smooth, soft, and pleasing to the eyes. At the same time, they also have the stiffness of polyester fabrics, wear-resistant, easy to wash, and no ironing. In order to overcome this shortcoming, more new polyester fabrics are available, such as highly hygroscopic polyester fabrics.
Application of recycled polyester yarn
Recycled polyester yarn is now generally used in the filler industry of furniture and toys, bedding, apparel industry, cotton industry, stitch-bonded fabric industry. Semi-finished products are mainly tested for oil-free filament viscosity. Recycled polyester staple fiber is a short fiber of a few centimeters to a dozen centimeters. In particular, the polyester cord strands used for tires are close to nylon in terms of performance. Polyester can also be used as materials for electrical insulation materials, acid-resistant filter cloths, pharmaceutical industrial cloths, etc. Synthetic fibers are widely used in various fields of the national economy due to their high strength, wear resistance, acid resistance, alkali resistance, high temperature resistance, light weight, warmth, good electrical insulation, and fearless mold worms. .
Application of polyester yarn
Polyester fabric is a kind of chemical fiber clothing fabric used in daily life. Its big advantage is that the shape retention is very good, therefore, it is suitable for jacket clothing. In general, polyester fabrics have the following characteristics: 1. Polyester fabrics have high strength and elastic recovery ability. Therefore, it is durable and non-scalding. 2. The polyester fabric has poor hygroscopicity, and it feels stuffy to wear. At the same time, it is easy to carry static electricity and stain dust, which affects the appearance. However, it is easy to dry after washing, and the wet strength hardly decreases, does not deform, and has good washability. 3. Polyester is a heat-resistant fabric in synthetic fiber fabrics, which has thermoplasticity and can be made into a pleated skirt with long pleats. At the same time, the polyester fabric has poor resistance to melting, and it is easy to form holes in the case of soot and sparks. Therefore, you should try to avoid contact with cigarette butts and sparks. 4. Polyester fabric has good light resistance, except that it is inferior to acrylic fiber, and its light resistance is better than fiber fabric. Especially the light resistance behind the glass is very good, almost comparable to acrylic. 5. Polyester fabric has good resistance to various chemicals. It is not damaged by acid or alkali, and it is not afraid of mold or worms.
