Study on Characterization and Fabric Properties of Natural Colored Cotton Fiber
In order to reduce the pollution of dyed fabric to the environment,the length,linear density and strength of natural colored cotton fiber are introduced,the reasons for difficulty in spinning high grade yarn are analyzed,and the methods to improve spinnability are given.Tak-ing brown colored cotton fiber as an example,the bursting property,wear resistance and air permeability of colored cotton fabric,dyed cotton fabric and white cotton fabric are tested and compared.It is pointed out that the main reasons for its poor spinnability and difficulty of spin-ning colored cotton fiber are its fine and short,low strength and large content of short fiber.The bursting strength and wear resistance of colored cotton fabric are higher than that of dyed cotton fabric and worse than that of white cotton fabric.The development of biological cultiva-tion technology and the application of digital and intelligent textile equipment make it possible for colored cotton fabric to replace dyed cotton fabric.
