Research On Physical & Chemical Properties And Product Development Of Regenerated Flax Fiber

The regenerated fibrilia resarched on the article was a kind of regenerated cellulosic fiber, which was made from jute and ambary and generated by the methods of wetspinning. It was produced formally in Jan, 2005. The fiber is also a new kind of regenerated cellulosic fiber after the bamboo fiber appeared. The theories about it were rare at present.The microstructure and fundamental characteridtics of the regenerated fibrilia are measured by the ways of the examination of fibers .the microstructure of the fiber was observed by the scanning electronic microscope.Result is that there are much stripe on the fiber's smooth surface at the longitudinal derection and the shape of the fiber's cross-section was quincunx. The curve of the regenerated fibrilia's infrared abosrption spectrogram showed that the chemical composition of the fibeur was identical to that of viscose fiber. The basic physical properties of the fiber were also measured include dry and wet breaking tenacity ,breaking extensinility, specific resistance, hygroscopic cordition and so on. We concluded though this tests that the strength and elongation of the fiber was different from that of natural fibrili. We also observed that the regenerated fibrilia's hygroscopic cordition was similar to the bamboo fiber and superior to both the natural fibrili and the cotton fiber.According to inhibition ring test, AATCC100 test and the test method of the fabric's antibacterial propertywhich is a standard of textile industy in china, quantitative and qualitative measurements were used to examine the antibacterial property of the regenerated fibrilia, bleaching fiber,dying pure spinning fabric. The results showed the antibacterial ability of the regenerated fibrilia was selected to different bacterium. The regenerated fibrilia and its fabric also has the antibacterial ability to some bacterium after being trated by bleaching and dyeing.The research on the dying performance of the regenerated fibrilia was done by the follow methods: residual liquid method used to test the rate of dye-uptake, washing method used to test the fixing efficiency, stripping and dissloving method used to test the combination between the dyes and the fiber. Some dyes which have two active group, such as Cibacron LS reactive dyes, Cibacron FN reactive dyes, M reactive dyes and B reactive dyes, were employed to study the dying performance of the regenerated fibrilia and the influence factor on the dying. Dying processes between the regenerated fibrilia and the natural fibrilia were compared at the same time. The result indicates that the dying behavior of the regenerated fibrilia is better than that of natural fibrilia. The reactive dyes are suitable to dye the fiber and The fiber The optimum condition of the four types of dyes were determined through the analysis of the influence factors on the dying regenerated fibrilia with reactive dyes.Based on the study on the property of the fiber,we made a spinning experiment and determined the reasonable spinning process flow and spinning process.So 32s and 80s/2 yarn were spun successfully.The regenerated fibrilia has excellent spinning property as cotton has and could be spun with the common equipment.The spinning process is feasible and simple to the fiber.Moreover the quality of the yarn is fineAccording to the excellent performance of the fiber, such as hygroscopic cordition,moisture-penetrability,draping property,sofeness and so on,the suitable knitting processing parameter were studied. We developed two styles of the regenerated fibrilia fabric.they have excellent appearances and comfortableness.
