1. Imitation linen fabric is a 100% polyester fabric.
Imitation linen fiber refers to a fiber that has the appearance and wearing performance of natural linen by physical or chemical modification. The raw materials of imitation linen fiber include polyester, acrylic, acetate fiber and viscose fiber, among which polyester filament and acrylic staple fiber have the best imitation linen effect.
2. Now imitation linen cloth has been used in many sneaker manufacturing and clothing industries, becoming a new fashion trend element. Most imitation cotton and linen fabrics are woven from polyester fibers. In terms of fabric appearance, the two are very similar. In terms of hand feel, the difference between the two is not big.
However, imitation cotton and linen fabrics are far inferior to real cotton and linen fabrics in terms of breathability and sweat absorption.
3. Processing methods of imitation linen fiber:
(1) Blending with linen fiber, which not only maintains the style and appearance of linen, but also gives chemical fiber the quick drying, good strength and wrinkle resistance.
(2) Filament imitation staple fiber processing, such as air texturing processing combined with false twist, compound twist, heavy twist and other special false twist processing, to make single or composite processed silk, giving hemp unique thick knots, luster and refreshing feeling.
(3) Different staple fibers are blended and mixed to form a combination yarn with multi-layer performance, giving the mixed yarn a breathable, soft, refreshing and dry feeling. -

The high temperature resistance of PVC leather depends on factors such as its type, additives, processing temperature and use environment.
The heat resistance temperature of ordinary PVC leather is about 60-80℃. This means that, under normal circumstances, ordinary PVC leather can be used for a long time at 60 degrees without obvious problems. If the temperature exceeds 100 degrees, occasional short-term use is acceptable, but if it is in such a high temperature environment for a long time, the performance of PVC leather may be affected.
The heat resistance temperature of modified PVC leather can reach 100-130℃. This type of PVC leather is usually improved by adding additives such as stabilizers, lubricants and fillers to improve its heat resistance. These additives can not only prevent PVC from decomposing at high temperatures, but also reduce melt viscosity, improve processability, and increase hardness and heat resistance at the same time.
The high temperature resistance of PVC leather is also affected by the processing temperature and the use environment. The higher the processing temperature, the lower the heat resistance of PVC. If PVC leather is used for a long time in a high temperature environment, its heat resistance will also decrease.
In summary, the high temperature resistance of ordinary PVC leather is between 60-80℃, while the high temperature resistance of modified PVC leather can reach 100-130℃. When using PVC leather, you should pay attention to its high temperature resistance, avoid using it in a high temperature environment, and pay attention to controlling the processing temperature to extend its service life. -

1. What kind of fabric is laser fabric?
Laser fabric is a new type of fabric. Through the coating process, the principle of interaction between light and matter is used to make the fabric present laser silver, rose gold, fantasy blue spaghetti and other colors, so it is also called “colorful laser fabric”.
2. Laser fabrics mostly use nylon base, which is a thermoplastic resin. It is safe and non-toxic and has little impact on the environment. Therefore, laser fabrics are environmentally friendly and sustainable fabrics. Coupled with the mature hot stamping process, a holographic gradient laser effect is formed.
3. Characteristics of laser fabrics
Laser fabrics are essentially new fabrics in which the microscopic particles that make up the material absorb or radiate photons, thereby changing their own movement conditions. At the same time, laser fabrics have the characteristics of high fastness, good drape, tear resistance and wear resistance.
4. Fashion influence of laser fabrics
Saturated colors and unique lens sense allow laser fabrics to integrate fantasy into clothing, making fashion interesting. The futuristic laser fabrics have always been a hot topic in the fashion circle, which coincides with the modern concept of digital technology, making clothing made of laser fabrics shuttle between virtuality and reality.
