| 摘要 |
A slide-fastener stringer foundation is formed of support tapes which are warp-knit. Two different types of weft filaments are used, one being textured and of limited shrinkability and the other being highly shrinkable. The tape so knitted is heat-shrunk so as to cause the shrinkable yarn to form the textured yarn into a mass of bulges or loops on the surface of the tape, thereby imparting to this tape a very smooth texture. |
