Development And Research Of Weft Knitting Terry With Bamboo Fibers

Regenerated bamboo fiber is getting more and more attention of people for its good capacity ofmoisture absorption, desorption, air permeability and antimicrobial properties. This paper introduced thestructure and performance of regenerated bamboo fiber, its mechanical properties were similar to theviscose fiber,which can satisfy the weaving requirements of cut pile fabric. Based on the characteristics ofbamboo fiber, it was allocated in different configuration mode to develop weft knitting terry with bamboofibers.This subject mainly studied the production process of plush fabric with regeneration bamboo fiber,and its physical performance; thermal-wet comfort properties and antimicrobial properties were studied.Combined with production practice, the main technology parameters and key technology of the regeneratedbamboo fiber plush fabric were discussed, the encountered problems and solutions in the developmentprocess were analyzed. On the basis of the original weaving process of polyester cut pile fabric, part ofknitting, dyeing and finishing process were improved to meet the requirements of bamboo fiber products.And then through experimental method, the thermal-wet comfort and antimicrobial properties of developedbamboo fiber plush were studied.The results showed that the physical properties of cut circle fabric with bamboo fiber were closelyassociated with the configuration mode and content of bamboo fiber, its mechanical properties associatedwith configuration mode of the bamboo fiber. When the bamboo fiber was only used as wool yarn,mechanical properties of the fabric was optimal,which was closed to the pure polyester fabric; whenbamboo fiber was used for binding yarn in cloth weaving, mechanical properties of the fabric has fallensharply. Antistatic performance is closely combined with bamboo fiber content, which enhanced with thecontent increasing of bamboo fiber. The thermal-wet comfort properties of cut pile fabric with bamboofiber were better than normal polyester fabric, it was not only influenced by the configuration of bamboofiber, but also affected by the content of bamboo fiber.The physical properties and thermal-wet comfortwere different when the bamboo fibers existed in difference way. The air permeability and wicking effectcan obviously increase when the bamboo fiber only used as binding filament participating in cloth weaving;the thermal insulation and moisture permeability were best when bamboo fiber was used as wool yarn andbinding filament; when bamboo fiber was only used as wool yarn, the thermal wet comfort of cut circlefabric between the both. The antimicrobial properties of cut pile fabric with bamboo fiber increased withthe increasing of bamboo fiber content, its antibacterial rate was positively related with the content ofbamboo fiber, while irrelevant with the configuration of bamboo fiber.In addition, the effects of the wool length,under yarn feeding and linear density on the thermal-wetcomfort properties of bamboo plush fabric was investigated by experimental method. The relationshipbetween structure parameters of fabric and permeability quantity, wicking height, heat preservation rate,heat transfer coefficient was found through the regression analysis. The results showed that the structureparameters of wool length, under yarn feeding and linear density have significant influence on the heat-moisture comfort of cut pile fabric. The wool length was significant influence on permeability and thermalinsulation. The wool length was negatively correlated with air permeability, while positively correlatedwith clo value. The backing yarn sending has a positive correlation with moisture permeability, itscorrelation coefficient was0.9973. Therefore, we can adjust the structure parameters of cut pile fabric withbamboo fiber to achieve optimization of thermal-wet comfort.
