石家庄市针织厂在解决原材料选用与采购方面应用价值工程,初见成效。 (一)功能不变,成本下降 该厂生产的纯棉汗衫、棉毛衫,属中档大众产品。缝纫线规定应用60S/3棉线或涤棉线。但在滚领、滚边工序,这两种线不能适应高速缝纫机要求,不得不长期采用高档80S/4精梳丝光全棉宝塔线,优材次用,万米线多花二元八角,全厂全年多花二万余元。 Shijiazhuang Knitting Factory applied value engineering in the selection of raw materials and procurement, and achieved initial success. (A) The function is unchanged, the cost is reduced The pure cotton shirts and cotton sweaters produced by the factory are mid-range public products. The sewing thread specifies the application of 60S/3 cotton or polyester cotton thread. However, in the process of rolling collars and piping, these two types of cables cannot adapt to the requirements of high-speed sewing machines, and they have to use high-grade 80S/4 combed mercerized cotton pagoda lines for long-term use. It spends more than 20,000 yuan a year.
