Description

Technical Field

[0001] The utility model belongs to the technical field of grey cloth leveling, and relates to a device for leveling elastic grey cloth. Background Art

[0002] Stretch fabric is a kind of elastic textile, which is widely used in clothing, home decoration, car interior and other fields. In clothing, stretch fabric is mainly used to make tights, sportswear, underwear and other clothing that require high elasticity. Its excellent elasticity and comfort allow the wearer to move more freely while maintaining a comfortable feeling. In the textile production process, the flattening of stretch fabric is a crucial link. The main purpose of the flattening process is to remove wrinkles in the fabric through a series of mechanical devices, such as flattening rollers, to make its surface smooth and flat, and provide a good foundation for subsequent processing procedures such as printing, dyeing, cutting, etc. When the flattening roller cannot keep a close fit with the surface of the stretch fabric during the flattening process, a series of problems will arise.

[0003] The wrinkles on the surface of the grey fabric cannot be effectively removed, which directly affects the appearance quality of the grey fabric. In the subsequent processing, these wrinkles may be further magnified, resulting in obvious defects on the finished fabric surface, reducing the overall quality of the product.

[0004] This will make the grey fabric easily deformed when subjected to external forces, affecting dimensional stability. In the subsequent processing and use process, this dimensional instability may cause problems such as shrinkage and deformation of clothing, seriously affecting the wearing comfort and service life of clothing. Therefore, a stretch grey fabric flattening device is urgently needed to solve the above problems. Utility Model Content
