丝棉混纺纱香港市场称之为“混纺丝”。系采用绢丝落绵和棉为原料混纺而成,可制作内衣、围巾、帽子、手套等纺织品,应用于机织、针织以及手工编织业的生产。其织物厚实丰满、穿着坚牢、富有弹性、滑挺光洁、吸湿耐水性好。该产品的开发,开拓了丝类混纺产品的新门类,增加了纺织品的出口量;同时,改变了绢纺落棉廉价出口的被动局面,为国内绢纺落绵资源的综合利用开辟了新的途径。我厂从1984年开始,在棉纺设备上纺制55%绢丝落绵与45%棉混纺的8~21英支丝棉 相似文献

In this work, we describe a novel facile method to prepare long one-dimensional hybrid nanofibers by using hydrated bacterial cellulose nanofibers(BCF) as a template. Silver(Ag) nanoparticles with an average diameter of 1.5 nm were well dispersed on BCF via a simple in situ chemical-reduction between AgNO3 and NaBH4 at a relatively low temperature. A growth mechanism is proposed that Ag nanoparticles are uniformly anchored onto BCF by coordination with BC-containing hydroxyl groups. The bare BCF and as-prepared Ag/BCF hybrid nanofibers were characterized by several techniques including transmission electron microscopy, X-ray diffraction, thermogravimetric analyses, and ultraviolet-visible(UV-Vis) absorption spectra. The antibacterial properties of Ag/BCF hybrid nanofibers against Escherichia coli(E. coli, Gram-negative) and Staphylococcu saureus(S. saureus, Gram-positive) bacteria were evaluated by using modified Kirby Bauer method and colony forming count method. The results show that Ag nanoparticles are well dispersed on BCF surface via in situ chemical-reduction. The Ag/BCF hybrid nanofiber presents strong antibacterial property and thus offers its candidature for use as functional antimicrobial agents. 相似文献
