Transfer printing section warped yarns for shadow tissues - permits mfr. of warp printed warp knitted fabrics

摘要

Warp printed fabrics are produced in four stages:- the web of threads is prepared by section warping; the web is transfer printed whilst heated and pressed by an endless blanket, against a continuously running transfer carrier; the printed web is wound on to a beam; and the fabric is woven or warp-knitted. Before being introduced into the printing machine, the free ends of the warp thread web are glued side by side and parallel to a thin temporary support such as a sheet of paper, and to prevent soiling of the blanket, a continuous sheet of kraft paper is fed in between it and the web. It is no longer necessary to weave the warp loosely before printing and then remove the temporary weft before the beam is finally woven, thus saving up to 70% of the weaving costs.
