The effect of some knitting factors such as the machine gauge, the depth of stitch draw, the input tension, and the take-down weight on the end breakage rates in plain-weft knitting zone due to yarn joints (airsplices, weavers knots and fisherman's knots) is investigated experimentally, using a cotton yarn (30s/1).
The results obtained are as follows :
(1) The knitting defect due to airsplices is hardly occurred for every knitting condition. Airsplice is a very usefull yarn joint on weft knitting.
(2) The knitting defect due to weavers knots or fisherman's knots almost causes knitting holes by end breakages in a plain-weft knitting zone. The end breakage occurs near the knot on the take-down side.
(3) The end breakage rate in a plain-weft knitting zone due to weavers knots or fisherman's knots increases together with the increase of the machine gauge, the depth of stitch draw, the input tension, and the take-down weight.
(4) For every knitting condition, the end breakage rate in plain-weft knitting zone due to fisherman's knots is more than that due to weavers knots.
