Fuzziness Influence on Polyester DTY

The overall yarn is too much, the frictional resistance caused by the friction and slip of yarn on the surface of the bobbin increases, which will cause the loss of strength and elasticity of the warp yarns. At the same time, the phenomenon of static electricity accumulation is particularly obvious during the friction between the filaments. Absorption or rejection of each other, easily kinked yarn together, resulting in frequent warping head warping, warping process can not be carried out.

Part of the Polyester Yarn warping tension is too large, warping tension yarn uneven, affecting the production of sizing and pulp shaft quality. Sizing, the hairiness can not be good appressed, coupled with warp in the weaving process by menopause films, healds, steel reed scraping, broken monofilament more easily bonded together, and easy to produce static electricity, so that the polyester DTY body surface of the tower stands with the neighboring polyester DTY entangled to form a soft ball, resulting in an unclear opening in the weaving. A "three-jump" defect occurs. In particular, when a single silk thread is severely warped, warping warps excessively, resulting in unintended drafting of the polyester DTY, which eventually results in chromatic aberration of the finished fabric by the monofilament. Among them, the processing of fine denier high density fabric or shuttle production problems more pronounced. Frequent open parking is also likely to cause parking stalls, especially in the lower density fabric and shuttle loom appear more. Unpredictable to open the front of the wool yarn, affecting the jet weft injection tension, resulting in weft distortion, forming a continuous straight "weft contraction."

When the weft yarn is more, the mutual friction and cohesion between the yarns will increase, and the unwinding performance of the yarns will decrease. During weaving of high-speed shuttleless weft yarns, weft insertion speed is high, Weaving can not be carried out.
