Production technology measures of Tencel cotton blended yarn interweave elastic fabric were discussed. Tencel/cotton 70/30 14. 7 tex x2 was selected as warp,9. 8 tex×2(44.4 dtex)combed cotton spandex covered yarn and 167 dtex(44.4 dtex)modified polyester filament spandex covered yarn were selected as weft,the fabric was interwoven. In winding process,processing principle of less tension and elongation,lower speed,keeping elasticity and reducing abrasion was used to ensure loom efficiency. In warping process, tensions of single yarn and piece yam were controlled strictly to ensure smooth yarn path. In sizing process, processing principle of less tension and elongation, concentrating on soaking and covering was adopted,size mixture with higher concentration and lower viscosity was used. In weaving process, warp tension was controlled well and weft-inserting parameter was selected rationally. Through optimizing processing, loom efficiency can be reached above 92% , storage rate of first-class product can be reached above 95% ,production demand can be reached.%探讨Tencel棉混纺纱交织弹力织物的生产技术措施.以Tencel/棉70/3014.7 tex×2为经纱、9.8 tex×2(44.4 dtex)精梳棉氨纶包覆纱和167 dtex (44.4 dtex)改性涤纶长丝氨纶包覆纱为纬纱进行交织,络筒遵循“轻张力、低速度、低伸长、保弹性、减磨损”的工艺原则,保证好轴率；整经严格控制单纱与片纱张力,保证各纱线通道光滑；浆纱采用“小张力、低伸长、渗透与被覆兼顾”的工艺原则,选择高浓低黏类浆料；织造控制好经纱张力,合理配置引纬工艺参数.通过工艺优化,织机效率达到92％以上,产品入库一等品率达到95％以上,满足了生产要求.
