氨纶面料最大的优点是弹性好,可以拉伸5-8倍,不老化,氨纶不能单独织布,一般都与其他原料织在起,氨纶比例大约在3-10%之间,泳装面料氨纶的比例达到20%。
氨纶纤维是具有高断裂伸长(400%以上 )、低模量和高弹性回复率的合成纤维。氨纶具有高延伸性(500%~700%)、低弹性模量(200%伸长,0.04~0.12克/旦)和高弹性回复率(200%伸长,95%~99%)。除强度较大外,其他物理机械性能与天然乳胶丝十分相似。它比乳胶丝更耐化学降解,具有中等的热稳定性,软化温度约在200℃以上。
用于合成纤维和天然纤维的大多数染料和整理剂,也适用于氨纶的染色和整理。氨纶耐汗、耐海水并耐各种干洗剂和大多数防晒油。长期暴露在日光下或在氯漂白剂中也会退色,但退色程度随氨纶的类型而不同,差异很大。
The biggestadvantage of Spandex fabric are good elasticity, can stretch 5-8times and aging. But spandex can not woven alone and woven togetherwith other fabric. The ratio of polyurethane materials in it isabout 3-10%. The proportion of spandex fabric of swimsuit reachesto 20%.
Spandex fiberis the synthetic fiber with high elongation (400 percent), the lowmodulus and high elastic recovery rate. Spandex have highextensibility (500), low 700% ~ elastic modulus (200% elongation,0.04 ~ 0.12 g/denier) and high elastic recovery rate (200%elongation, 95% ~ 99%). Besides higher intensity, the physical andmechanical properties are similar with natural latex wire.According to chemical degradation, it is more than the latex wire.It also has medium thermal stability and with softening temperatureof about 200 degrees Celsius.
Most dyes andfinishing agent can be also applied to synthetic fiber and naturalfibers. Spandex can bear sweat, seawater and various dry and mostsunscreen lotion. With long-term exposure to sunlight or inchlorine bleach, it will fade away. But different types of spandex,difference of faded degree is large.
