Abstract:
Naturally colored cotton (NCC) offers an environmentally friendly fiber for textile applications. Processing white cotton fiber into textiles requires extensive energy, water, and chemicals, whereas processing of NCC skips the most polluting activity, scouring-bleaching and dyeing; therefore, NCC provides an avenue to minimize the harmful impacts of textile production. NCC varieties are suitable for organic agriculture since they are naturally insect and disease-resistant, salt and drought-tolerant. Various fiber shades, ranging from light green to tan and brown, are available in the cultivated NCC (Gossypium hirsutum L.) species. The pigments responsible for the color of brown cotton fiber are proanthocyanidins or their derivatives synthesized by the flavonoid pathway. Due to pigments, the NCC has excellent ultraviolet protection properties. Some brown cotton varieties exhibited superior thermal resistance of fiber that can be used to make fabrics with enhanced flame retardancy. Here, we review molecular mechanisms involved in the pigment production of brown cotton and challenges in breeding NCC varieties with a wide range of colors but without penalty in fiber quality. Also, we discuss opportunities for NCC with flame-retarding properties in textile applications.
摘要:
天然彩色棉(NCC)为纺织应用提供环保纤维。将白色棉纤维加工成纺织品需要大量的能源,水,和化学品,而NCC的处理跳过了污染最严重的活动,精练-漂白和染色;因此,NCC提供了一种将纺织品生产的有害影响降至最低的途径。NCC品种适合有机农业,因为它们具有天然抗虫和抗病能力,耐盐和耐旱。各种纤维色调,从浅绿色到棕褐色,在栽培的NCC(陆地棉)物种中可用。负责棕色棉纤维颜色的色素是通过类黄酮途径合成的原花色素或其衍生物。由于颜料,NCC具有优异的紫外线防护性能。一些棕色棉品种表现出优异的纤维耐热性,可用于制造具有增强阻燃性的织物。这里,我们回顾了棕色棉色素产生的分子机制,以及培育具有多种颜色但不影响纤维质量的NCC品种所面临的挑战。此外,我们讨论了具有阻燃特性的NCC在纺织品应用中的机会。
