Solida is the abbreviation of polystonate fiber and is an elastic fiber. Generally consisting of multiple long wires, the less the theoretical roots, the better the uniformity of the strips, and the less chance of the overlapping form. The spandex is highly elastic and can be extended by 6 to 7 times, but with the disappearance of the tension, it is quickly restored to the initial state. The molecular structure is a chain, soft and extended polymethlate. The hard chain segments are connected together to enhance their characteristics.
The spandex is generally composed of multiple long silk, generally 10d/root. At present, 15D/root, or even 20D/root. The less the theoretical roots, the better the uniformity of the strips. The production solution DMAC of French spinning wire is harmful to the liver of the human body. Generally, 10D/root contains 0.5mg/kg, such as 15D/root contains 0.7mg/kg, exceeding the standard. When producing SPANDEX, for the tension, the number of tube, the fracture strength, the breakdown, the formation, the amount of oil attachment, the elastic recovery rate, etc., you must pay special attention. Pay attention to one -sided cloth.
Elastic fibers are divided into two categories: one is polyester chain; one is polyether chain. Polyester elastic fiber has strong anti -oxidation and oil resistance; polyether -like elastic fiber anti -mildew, and good anti -washing agents.
The spandex is a polyurethane fiber. Because of its excellent elasticity, it is also known as elastic fiber and has obtained a lot of applications on clothing fabrics. The main features of aminoly fabrics are:
1. Spandex elasticity is very high. Generally, the finished product does not use 100%polyurethane, and mostly mixes a ratio of 5 to 30%in the fabric. The various amino fabrics obtained have 15%to 45%comfortable elasticity.
2. The aminoly fabric is often made of composite gauze, that is, the spandex as the core, and use other fibers (such as nylon, polyester, etc.) to make the cortex into the core gauze elastic fabric. , No sense of oppression.
3. The appearance of the spandex elastic fabric is close to similar products that are used in the outer fiber fabric.

Elastic fibers are divided into two categories: one is polyester chain class; one is polyether chain. Polyester elastic fiber has strong antioxidant and oil resistance; polyether -like elastic fiber anti -mildew, and good anti -washing agents.
Second, the physical characteristics of spandex fabrics:
1. Has high -break and extension, low mold volume and high elastic response rate;
2. High extension, low elastic modulus and high elastic response rate;
3. More chemical degradation than latex wire, with moderate thermal stability;
4. Its polymer chain is composed of a low -melting point, non -fixed "soft" chain segment as the mother body and the "hard" chain segment of the high melting point and crystallization in it;
5. Have good chemical resistance, resistant pH, chemical agents, organic solvents, dry washing agents and bleaching agents, as well as sun -resistant and snowy, but not resistant to oxides, which can make fibers yellow and powerful reduce;
6. Solida is generally not used alone, but is mixed with a small amount.
Solida can be used to meet the needs of comfort that requires stretching, but the ratio of general clothes is small. When use, other fibers such as cotton and polyester are added to minimize the gloss.
