IntroductionCotton hollow yarn is one of novel products . Thespinning technique is to reduce the fiber packing density inthe center of the yarn, and to i mprove the softness andbulkiness of the conventional yarn and its products . To getcotton hollow yarns , water soluble PVA filament[1]orstaple fiber is used as the core which will be removedlater ,and cotton fibers as sheath wrapping on the core .The outstanding properties[2]of cotton hollow yarnproducts are that they promote a lighter weig… 相似文献

The Absorption and permeability of air-jet textured glass fiber yarn and its fabric and bonded tenacity of the fabric have been studied in relation to the main parameters, air supplied pressure and overfeed ratio. It has been observed that increasing the level of main parameters improves the coated ratio of the textured yarn and its fabric as well as the bonded tenacity of the fabric made of textured yarn. Comparison of absorption or permeability between textured and supplied yarns, and comparison of absorption or permeability and bonded tenacity between the two kinds of fabrics have been elucidated. 相似文献
