Why is it not easy to smash the silk stockings? The weather is getting warmer, and the little fairies are all ready to show their long legs. They want to be beautiful and the stockings are indispensable. Although the stockings are beautiful, they are often not durable. If you accidentally scratch it, you will be spoiled and show it to you. The new "anti-hook" and "arbitrary cut" stockings on the market can be said to capture the pain points of consumption. So, what is the principle of their anti-hooking? After the ordinary silk stockings are hooked, the spandex which was originally in tension will be quickly retracted after breaking. The stable fabric structure is instantly broken, and the coils are like a domino effect, which dissociates the long strips like the ladder. After the low-melting spandex is used, the coil and the coil are bonded together at the junction point, so that even if the spandex breaks during the use, scratches, cuts and repeated stretching, the hole will only be spotted ( When worn, the hole will slightly spread into a small circle shape without spreading in a strip shape, and it will not easily cause the wire to be dissipated, burred and curled.

In fact, the difference between them and ordinary stockings is the use of a special elastic fiber - low melting point spandex (melting point around 180 ° C), by using this spandex, combined with the corresponding weaving process, because of the melting point of this spandex Low, in the process of dyeing or heat setting (dry heat setting conditions of 170 ~ 190 ° C, wet heat setting conditions of 105 ~ 125 ° C) will melt, at the point of interlacing, make spandex and spandex, spandex and other fibers Bonded together.
The use of this spandex not only simplifies the cutting process of the fabric, prolongs the service life of the fabric, but also enhances the wearing comfort, and can be used for various personalized shapes without fear of dispersing.
In addition to application in stockings, low-melting spandex can also be used in the development of underwear products. Ordinary spandex-containing fabrics tend to have problems such as off-line and burrs after cutting. Usually, the edge of the cut is folded into two layers and then stitched, or the cloth is sewn with a cloth tape or the like. After using the low-melting spandex, it can effectively restrain the burr off-line after the fabric is cut, and the fabric can achieve the effect of “deliberate cuttingâ€, which greatly improves the working efficiency of sewing, and the comfort of underwear is also worn without edging. This has been greatly enhanced, and this "concentric" fabric is increasingly used in high-end underwear and T-shirts.
Since the anti-dissociation spandex is a high value-added spandex product, the production technology is difficult. At first, only a few powerful transnational spandex companies have the ability to produce, mainly including Japan's Nisshinbo's Mobilon, Asahi Kasei's Roica, and the United States. Invista's Lycar Fusion, etc., and the product supply and demand pattern is stable, some of the excellent quality of imported products are very tight, and its price is about 250,000 ~ 280,000 yuan / t. With the rapid growth of the anti-dissociation spandex fashion demand, the domestic spandex enterprises have gradually increased the development of this type of spandex. The domestically produced products on the market mainly include Haining Xingao's LM Spandex and Huafeng Spandex's millennium low-temperature easy-adhesive spandex. The price is between 160,000 yuan and 200,000 yuan / t.
