Unlike the horizontal stripes that can be seen everywhere, vertical stripes are relatively rare and usually appear on shirts. In fact, a vertical striped T-shirt + simple jeans can be simple and stylish with a pair of shoes.

This stripe cotton T shirt contains polyurethane fibers. Polyurethane fiber is a block copolymer fiber with polyurethane as the main component. Macromolecules are composed of soft and hard segments. The soft segment is composed of non-crystalline polyester or polyether, with a very low glass transition temperature and high elasticity at room temperature. When stretched at room temperature, the fiber can produce a large amount of large elongation deformation and has excellent resilience. This allows this cotton t shirt to maintain its original shape even when worn for a long time.

The Performance of Spandex

1. Elasticity

Spandex fiber has great elasticity. Under normal circumstances, it can be stretched to 4 to 7 times its original length, and its recovery rate is almost 100% under 2 times of stretching, and its resilience rate is 95 when it is stretched 500%. ~99%, which is unmatched by other fibers. Generally speaking, in the molecular structure of spandex fiber, the larger the molecular weight of the soft segment, the stronger the elasticity and resilience of the fiber. Polyether spandex has higher elasticity and resilience than polyester spandex; chemically crosslinked spandex Its resilience is better than that of the physical cross-linking type.

2. Strength

Because of its elasticity, spandex cannot be tested for strength in the same way as other fibers. When the fiber is stretched to the maximum length, the fiber becomes thinner, and the strength measured at this fineness is the effective strength. Due to the different structure of spandex, its strength is about 4 to 5 cN/dtex, while the breaking strength is 0.44 to 0.88 cN/dtex in the dry state and 0.35 to 0.88 cN/dtex in the wet state. Since the moisture absorption of spandex fiber is extremely low (0.3% to 1.3%), the plasticizing effect of water on spandex is not obvious, so its wet strength is only slightly lower than the dry strength. When the breaking strength of spandex fiber is close to 0.88 cN/dtex, its elongation energy can reach 350% to 600%. Of course, the breaking elongation of spandex is large, and its breaking work is also great.

3. Heat resistance

The softening point of spandex is 205～210℃, it turns yellow at 150℃, and its strength decreases at 190℃, even sticky. Therefore, the general setting temperature of spandex fabric should not exceed 175～180℃. Due to the difference between the structure of the fabric and the winding method of spandex and other fibers, the setting temperature of covered yarn fabrics generally does not exceed 180°C, the setting temperature of core-spun thin fabrics can reach 190°C, and the setting temperature of core-spun thick fabrics can reach 195. ～210℃. Of course, the setting temperature depends on the shrinkage rate and elasticity requirements of the finished product. Domestic general customers have no quantitative indicators for the elasticity of the finished product, and only require the finished fabric to have a slight elasticity, so the control of the setting temperature is only determined by the shrinkage rate of the finished product. If the finished product has elastic index requirements, the elastic loss of the fabric should be controlled throughout the process. When designing the process, first desizing the grey fabric and then loosely washing it with water to measure the elastic recovery of the grey fabric (between about 25% and 35%), and then formulate an effective process according to the elasticity requirements of the finished product.

4. Dyeing performance

For core-spun yarn, covered yarn and twisted yarn, since the spandex is almost completely covered by the external fiber after dyeing, it is generally unnecessary to consider whether the spandex is colored or not, but the spandex itself can be directly dyed, vat dyes, acid dyes, and disperse dyes. Dyes, reactive dyes, etc. However, the color fastness of direct dyes and reactive dyes is poor (especially for dark colors). If the bare filaments of spandex fibers or spandex fibers are not completely covered by external phase fibers, the dyeing of spandex must be considered.
