为了解家用洗涤对天然彩色棉织物性能的影响,制备了含天然彩色棉的机织物,采用FAST对洗涤后织物的风格进行研究。研究表明:首次洗涤对织物风格的影响最大,织物在初次洗涤后有变柔软和丰满的趋势,随着洗涤次数的增加,织物风格丰满度逐渐下降而使织物有变滑爽的趋势;与纯白棉织物相比,含彩色棉的织物经过家用洗涤后有挺括、成型性变好的趋势;Lyocell纤维的加入,使彩色棉织物变得滑爽,家用洗涤后织物的剪切刚度下降,穿着相对舒适。
For better understanding the effect of home laundering on the properties of naturally colored cotton woven fabrics, a series of naturally colored cotton containing woven fabrics were made using yarns of NCC and its blend, and the effect of home laundering on the hand of naturally colored cotton based woven fabrics was examined. FAST( Fabric Assurance by Simple Testing)system was used in the investigation. The study showed that the first washing cycle is the critical one which affects the hand of washed fabric most —— the fabric will become softer and fuller; an.d subsequent washings will make the fabric hand become smooth with decreased fullness. Compared to the white cotton based materials, the naturally colored cotton based fabric has stiffer hand and better garment shaping performance. When incorporated with Lyocell fiber, the naturally colored cotton based woven fabric has smoother hand, and after wash, become more comfortable in wear.
