50D*50D weft twist imitation memory

What types of memory fabrics are there?

In the textile market, memory fabrics are relatively mature and the price is relatively affordable. Because of their non-iron properties, they are very popular in the fabric market. There are generally three kinds of imitation memory fabrics, semi-memory fabrics, and full-memory fabrics on the market. The three kinds of fabrics are mainly due to different processes and materials, and the finished products produced are also different.

The so-called "semi-memory" in the market means that "memory fibers" are used in a single direction in the warp or weft direction, while "full memory" usually refers to fabrics made of "memory fibers" in both the warp and weft raw materials. The "imitation memory" fabric is made of filament, which is more difficult than full memory and real memory in terms of dyeing technical requirements. The imitation memory fabric mainly has a certain memory function through PET twisting, but the memory effect of the fabric produced by PTT is not as good, and the price is cheaper than the full memory fabric.

In the fabric market, many manufacturers use ordinary polyester yarn for twisting, light-alkali or no-alkali treatment to lie memory fabrics. Most of the fabrics produced by this process feel jerky, have poor toughness and have poor elastic recovery after deformation. , It is relatively weak and cannot achieve the effect of memory fabrics.

Some manufacturers will use PU coating to improve the elasticity of such counterfeit memory fabrics. The feel is somewhat similar to real memory. However, due to the inherent shortcomings of counterfeit memory fabrics, there is still a big difference between real memory fiber fabrics.

The memory fabrics produced by these unscrupulous manufacturers are not "imitation memory" fabrics in the true sense, but counterfeit memory fabrics. Real memory fiber fabrics can be deformed at will, and the bending place when the deformation occurs is fabric instead of a strip. thread, easy to recover, and very elastic and tough.

Therefore, when purchasing imitation memory fabrics, semi-memory fabrics, and full-memory fabrics, it is necessary to clearly understand the process and materials of these fabrics. Do not buy fake "memory fabrics" because of small things.
