The difference between recycled polyester and polyester
What is recycled polyester yarn
Regenerated polyester fiber refers to the use of polyester fabrics, waste polyester bottle flakes, spinning waste, air bubbles, and pulp as raw materials. The waste bottle flakes are crushed and washed, and the mixture of various raw materials is dried, melt-extruded, spun, Winding, bundling, drawing, crimping (at the same time adding different oils when crimping according to customer needs), relaxing heat setting, and cutting to form polyester fibers of different lengths.
The length is generally 32-102mm, and the fineness has various specifications from 1.5D-20D, which is a full use of renewable resources. Because of its low cost and good performance, it has a broad market. There are many different varieties of recycled polyester staple fiber, such as ordinary fiber, hollow fiber, triangular yarn, flame-retardant fiber, etc. Bonded fabric industry.
What is polyester yarn
There are many types of polyester fiber fabrics There are many types of polyester fiber fabrics. In addition to woven pure polyester fabrics, there are also many products that are blended or interwoven with various textile fibers to make up for the shortcomings of pure polyester fabrics and exert better performance. . At present, polyester fabrics are developing towards synthetic fibers such as wool, silk, hemp, and buckskin. 1. Polyester imitation 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 free ironing, etc., and is very popular among consumers. Common varieties are: polyester silk, polyester crepe, polyester satin, polyester georgette, polyester interwoven silk, etc. These varieties have the elegant drape of silk fabrics, which are smooth, soft and pleasing to the eye. At the same time, they also have the stiffness of polyester fabrics, which are wear-resistant, easy to wash, and iron-free. In order to overcome this shortcoming, more new polyester fabrics, such as high moisture absorption polyester fabrics, have emerged.
Application of Regenerated Polyester Yarn
Regenerated polyester yarn is now commonly used in the stuffing industry for furniture and toys, bedding, clothing industry, cotton industry, and stitched fabric industry. Semi-finished products are mainly tested for oil-free filament viscosity. Regenerated polyester staple fiber is a few centimeters to ten centimeters short fiber. In particular, polyester cords for tires are close to nylon in performance. Polyester can also be used as raw materials for electrical insulation materials, acid-resistant filter cloths, and pharmaceutical industrial cloths. 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 retention, good electrical insulation, and are not afraid of mold. .
Application of polyester yarn
Polyester fabric is a kind of chemical fiber clothing fabric used in daily life. One of its great advantages is that it retains its shape very well, so it is suitable for jackets. In general, polyester fabrics have the following characteristics: 1. Polyester fabrics have high strength and strong elastic recovery ability. Therefore, it is durable and does not burn. 2. Polyester fabric has poor hygroscopicity and feels stuffy when worn. At the same time, it is easy to be charged with static electricity and get dusty, which affects the appearance. However, it is easy to dry after washing, has almost no decrease in wet strength, does not deform, and has good washability. 3. Polyester is a heat-resistant fabric among synthetic fiber fabrics. It is thermoplastic and can be made into long pleated pleated skirts. At the same time, the melting resistance of polyester fabric is poor, and it is easy to form holes when encountering smoke, dust and sparks. Therefore, contact with cigarette butts and sparks should be avoided as much as possible. 4. Polyester fabric has good light fastness, except that it is not as good as acrylic, and its light fastness is worse than that of fiber fabric. In particular, the light resistance behind the glass is very good, almost comparable to acrylic. 5. Polyester fabric has good resistance to various chemicals. Not damaged by acid and alkali, not afraid of mildew, not afraid of insects. Its light resistance is better than fiber fabrics. In particular, the light resistance behind the glass is very good, almost comparable to acrylic. 5. Polyester fabric has good resistance to various chemicals.
