Definitions

• This invention relates to a process of'sizing and dressing yarns or threads in general for weaving, warp or circular knitting or other textile purposes, and is applicable to yarns composed of or containing natural fibres or cellulose acetate or other artificial filaments or fibres.
• packages of yarn or thread, wound'on bobbins, cops,.pi rns,'tubes, spools or similar carriers are immersed in a solution of a sizing or dressing agent (hereinafter termed a sizing agent) in a volatile solvent until they are thoroughly impregnated therewith, the ack- -ages of yarn orthread are then remove and the yarn or thread is dried by evaporation of the solvent and wound continuously on to. banking frames, bobbins'or other usual ,or desired carriers for the sized or dressed yarn or thread.
• the drying is conveniently eifected during the operation of winding the yarn or thread onto the final carrier, but may also be performed wholly or partly while the yarn isstill in its original package and before the winding operation takes "place.
• the yarn or thread may even be allowedto dry slowly on the bobbin or other original carrier,- and then be stored and Wound ofi when required.
• volatile solvents such for example as water, benzene, toluene or xylene maybe employed. Mixtures of volatile solvents with other solvents,cfor'instance solvents that volatilize with difiiculty, such as paraflin oil, can also be used.
• the sizing or dressing agent employed should be capable of forming a coatmg on the yarn or thread that is freefrom brittleness and liability to dust bit, and at the same time is free from stickiness.
• Sizing compositions of a suitable .character are described and claimed in British Patent Specifications Nos. 244,947 and 244,979, andin the corresponding U. S. specificationsSNos. 728,799
• -riers are placed in a vessel. provided with a closure which can be rendered air ti ht.
• the vessel is then evacuated and a solution
• the yarn' so nately as often as may be necessary to ensure complete impregnation of the package.
• the solvent is evapprated, leaving an even layer of the sizing or dressing agent on the yarn.
• the evaporation of the solvent may be efie'cted at ordinaryii,
• the yarn or thread maybe passed over a hot plate or steam pipes in order to facilitate the 1 evaporation, or may be subje ctedto'theac tion of currents of air or other gas or vapour aided, if desired, by the a plication of heat or reduced pressure for the same purpose.
• the evaporated solvent may be recovered by absorption or condensation any ofthe 100.
• the solvent may be wholly or partly evaporated before the package is unwound.
• the packages of yarn or thread may be stored for any desired period in chambers through which a current of warm air may be passed or allowed to circulate, and then, after the evaporation of the solvent has been completed, or has proceeded to any de-' sired extent, the packages of yarn may be removed and wound off on to the final carrier. the evaporation of the solvent being completed when necessary during the winding operation.
• the amount of size or dressing deposited on the yarn or thread may be varied in accordance-with requirements by varying the concentration of the solution used.
• Process for sizing yarn comprising impregnating yarn while in the form of a package wound on a earner with a solution of a sizing agent in a volatlle solvent, exposing the package to conditions pefmitting evaporation of solvent, and afterwardsunwindin the yarn from its original carriers-andwin ing it on to a carrier for the sizedkyarn, the
