Patent GB-383610-A (GB)
Title: Improvements in the treatment of yarns or threads
IPC: D06M11/46
Filed: 1931-02-10
Abstract: Yarns containing continuous filaments of natural or artificial silk are rendered amenable to textile operations, e.g. knitting, weaving, winding into packages, &c., by applying thereto a finely-divided pigment or other solid material.  The yarn, dry or wetted with a liquid or solvent, may be run through the dry powder, but preferably, the material is ground with liquids, oils or finishes and applied to the yarn in transit to packages or hanks.  Oils, finishes and pigments may be separately applied. Hanks may be dipped in baths containing the finishes, or the finishes may be forced through the windings of a bobbin, cop, or other package.  The finishes may be applied to artificial filaments immediately after formation, either within or outside the spinning cell.  Artificial filaments may consist of cellulose organic esters or ethers, or reconstituted cellulose.  Solid materials specified are barium sulphate carbonate and phosphate, calcium sulphate and carbonate, titanium dioxide, pumice, glass, carborundum, emery, kaolin and starch.  A suitable quantity of pigment &c. is 0,2-2 per cent on the weight of the yarn with 5-15 per cent of oil &c. finish.  The pigment &c. may be removed from the finished fabric by scouring or during dyeing or finishing treatments; in certain cases it may be removed by chemical treatment, e.g. calcium carbonate or barium phosphate may be removed by treatment with dilute hydrochloric acid.  In an example, a cellulose acetate yarn is passed over the surface of a slowly rotating roller dipping into a lubricant containing 9 parts diethylene glycol and one part titanium dioxide, the rate of feed being such that 8-10 per cent of diethylene glycol is applied to the yarn.
