Functional Fibre's Structure Testing And Performance Analysis

With the development of china market economics and people s standard,people have brought forward new requests on fabrics and clothing industry.More enterprises join in this great potential textile market of disease- preventing and body-strengthening and protecting.New special types of health- protecting fibres are being developed continuously. The choosing and producing of new types of health-protecting fibres provide more space for enterprises relating to weaving,clothing etc to develop new products. There are many types of high functional fibres,for example:minus hydronium fibre,which has been developed in recent years belonges to environment-protecting fibers.It s minus hydronium powder s releasing builds circumstance resembling narure,so as to present a clear and comfortable feeling,which is one that many fibre corporations recommend. The polyester fibre of resisting bacterium is one without which people can t live in modern times,but how to restrain the bacterium propagating excessively and keep people in health is a most important goal that fabrics and clothing industry are striving for.Fibre of resisting bacterium can kill the bacterium effectively with the ratio of more than 99% and it can restrain microbes. The polyester fibre of resisting ultraviolet radiation is also widely used. With the decreasing of ozonospheres in the atmosphere,there are more ultraviolet radiation in the sunlight which do harm to our skin,especially for those men working outdoors,it ismore important to think about the way to lessen the harm.The polyester of burning-resisting has attracted more attention at home and abroad and burning-resisting textiles has been advanced definitely by law in many countries.Our nation has also made strict claims in some special areas,such as fabrics in vehiciles and vessels,decorative fabrics in hotels.The everlasting burning-resisting fibres and textiles are badly needed.Infrared ray fibre is also a new functional one that can absorb and reflect infrared ray after being processed physically.It s functions include physical therapy wet-ejecting and bacterium-restraining.This warm-preserving material can absorb the emitting heat from our bodies,at the same time it can also absorb and reflect the needed 4-14 urn wavelength ultraviolet radiation and accelerate netaboIism.Fibre of resisting infrared ray is important in military areas. The purpose of manufacturing functional fibres is to get some utilizing functions. In allusion to some types of the functional fibre s performances and characters the paper mainly has this fibres microstructure scanned by electron microscrope.In addition we also discuss their differences of microstructure eroded by the plasm.Meanwhile by performing mechanics analysis we get theoretical analysis of their space-conglomerating structure.Finally we perform analysis of the ultraviolet radiation and analysis of the caloricr weightlessness.As a result these types of fibre not only keep their own fine traits,but also own good conglomerating structure ,crystal limit ,calorifics performance and mechanics performance. Compared with the ordinary fiber ,the neatness of high-contracted polyester fiber increases and it s diameter also increases. There are bubbles in the burning-resisting viscose fiber and it has smooth vertical structure . Cotton fiber of polyester series has fine performance in resisting being eroded and only a small part is eroded meanly. The effect of erosion on bacterium-resisting viscose fiber is not obvious ,while the effect on burning-resisting viscose fiber is themost obvious. The effect of erosion on ultraviolet-resisting viscose fiber is less than the burning-resisting fiber. We can come to the following conclusions. Compared with the ordinary polyester fiber,the breaking-strength of dyed polyester fiber decreases,while it s breaking-extension increases.The breaking-strength and breaking-extension of high-contracted polyester cotton fiber decreases .The stress of dyed-fiber and high-contracted fiber is less than the ordinary polyester cotton fibe...
