The present invention is forming process of weft-knitted fabric with thin mesh effect. In a weft knitting machine with back needle bed needle and special front needle bed needle capable of raising the loop on the needle, the basic stitch of the looping structure is first knitted with fine yarn in the back needle bed and the setting-on plus missed loop is then knitted with coarse yarn in the back needle bed. The missed loop may cross several needle wales, and the front needle bed needle acts for hanging missed loop only. After several continuous ranks are kitted, the front needle bed needle will raise all the missed loops inside the needle hook and transfer them to the hook of the back needle bed needle for retaining loop. The said process is circulated to form the weft-knitted fabric with thin mesh effect, and the fabric is suitable for use as decorating or fashionable dress material. |
