The memory fabric refers to a product with a certain original shape, which can return to its original shape and characteristics under the stimulation of specific external conditions (such as heat, machinery, light, magnetism or electricity) after deformation and fixation, and is initially applied to some alloy products. Memory fiber refers to some characteristics of the initial state that can be memorized when the fiber is formed at one time. The fiber can undergo any deformation after being formed. The deformation can be fixed under the action of lower temperature or external force. When the deformed fiber is stimulated by specific external temperature or external force, the fiber can return to the initial state. In short, the fiber can rapidly deform under the action of external factors and can rapidly recover the deformation under the action of external stress. Fabrics made of such fibers are called shape memory fabrics.
There are so-called semi-memory, full-memory and imitation memory fabrics in the market. The quality of fabrics varies greatly and the prices vary greatly. The so-called "semi-memory" in the market refers to the "memory fibers" used in the warp or weft direction, while the "full memory" usually refers to the fabrics woven with "memory fibers" as the warp and weft raw materials. There are also many manufacturers that use ordinary polyester yarns to twist and treat with light alkali or non-alkali to make false memory fabrics. Most of these fabrics are crude in hand feeling, weak in toughness, poor in elastic recovery after deformation, and relatively weak. Some people also use PU coating to improve the elasticity of this kind of fake memory fabric, which is somewhat similar to real memory in hand feeling. However, due to the inherent deficiency of fake memory fabric, it is still quite different from real memory fiber fabric. The real memory fiber fabric can be deformed at will, and the bending place when the deformation occurs is fiber instead of a line, which is easy to recover and has elasticity and toughness.
