The symbol of this small town in Jiangnan is the Tower of Jusha from South Song Dynasty. From the nineties of last century, Meili has begun her story as a leading industry cluster of warp knitting. Meili Town owns 46 warp knitting enterprises, and more than 560 family workshops, more than 1,800 sets of different kinds of warp knitting machineries. More than 70% of the domestic warp knitting machineries is bought by Meili town. The main products include more than 30 kinds of plush. The annual production capability reaches 10 tons and annual output reaches four billions. More than 30 companies sell their products to Russian, South Africa, Nigeria, Romania and Middle East. Meanwhile the development of the industry activate doubling, slitting, brushing, dyeing, gigging, home textile, apparel and other related industry. The town of Meili now owns a complete industrial chain from raw materials to warp knitting, finishing and final products.展开更多

The effect of knitting parameter on the elasticity of PBT /PET warp knitted fabric was analyzed. The increase of drawing density( from 16 to 26 courses per centimeter( CPC)) on machine resulted in the decrease of elongation at the weft direction. But,the elongation at the warp direction fluctuated as drawing density increasing. The yarn run-in speed influenced the elongation of PET /PBT warp knitted fabric as well. When the yarn run-in speed of GB1( front bar) was kept a constant,the increase of GB2( back bar) yarn run-in speed caused the gradual enhancement of the elastic elongation at the warp direction,but the different trends of the elastic elongation at the weft direction. When yarn run-in speed of GB2 was kept a constant,the increase of GB1 yarn run-in speed enlarged the elastic warp elongation from 104.16 to 124.97 mm,while the weft elongation decreased from 110.34 to 98.03 mm.Eventually yarn run-in speeds of GB1 and GB2 were retained at1 360 and 1 170 mm / rack respectively under 20 CPC drawing density. It could not only balance the two directions of elongation but also reach the highest elongation at both directions( 126. 32 and115.88 mm) under 100 N tension. These results provide a better understanding of characteristics of PET / PBT warp knitted fabric,and its elastic elongation and recovery behavior for development and effective applications.展开更多
