Definitions

  • Difiiculties are associated with the use of viscose or cellulose solutions as an agent for dressing woven textile materials or sizing yarn, on account of the fact that the fabric 5 or yarn which has been thus treated acquires a stil'hpaper-like and cold feel, and moreover its extensibility is rather low.
  • Fabrics which have been dressed by means of viscose have also the disadvantage that the cellulose regenerated from the viscose applied to the fabric frequently undergoes rupture when the material is stretched or pulled,
  • the coating exhibits numerous minute, or more or less coarse, cracks. Even in textile printing, particularly in pigment printing with viscose se/defects are apparent to an undesi able degree, and the viscose layers printed o the textile have a stiff feel, and. in many c ses become torn on being stretched, especially when they are not very thin.
  • This invention relates to a process for treating textile fibrous material (whether in the form of woven fabrics or of yarn) by dressing, sizing, printing,
  • the invention consists in the application of the discovery that the properties of the dressing, sizing, printed layers or the like, which consist of, or contain, cellulose regenerated from soluble derivatives of cellulose, for example from viscose from a cellulose solution, for example in cuprammonia, which has been applied to the fibrous material, are improved, especially in respect of feel and extensibility, if the dress-.
  • I ing, sizing or coating contains hollow spaces or bubbles dispersed throughout it, or throughout at least a part of it.
  • hol- 0 lows or bubbles may be produced by dressing, sizing or otherwise treating the material weighting or the or precipitated with a solution of a soluble modification of cellulose, for example viscose or with a solution of cellulose, containing a quantity of gas or of a substance capable of being caused to evolve a gas by a suitable treatment.
  • a solution of a soluble modification of cellulose for example viscose or with a solution of cellulose, containing a quantity of gas or of a substance capable of being caused to evolve a gas by a suitable treatment.
  • Fabrics or yarns treated in accordance with the invention have also a warm feel, and owing to the hollows in the dressing, sizing or the like, it is possible to produce even with small proportions of viscose or cellulose solution a" very full, rich dressing or sizing.
  • Material treated in accordance with the invention has a good ca pacity for extension, and fissures or cracks do not occur when the material is pulled or stretched.
  • the hollow spaces may contain the gas, for example air or carbon dioxide, or the gas may be removed, wholly or in part, from them, forexample, by dissolution, or with the aid of an increased or reduced pressure.
  • the gas for example air or carbon dioxide
  • the gas may be removed, wholly or in part, from them, forexample, by dissolution, or with the aid of an increased or reduced pressure.
  • a gas for example air, hydrogen or nitrogen
  • a gas may be emulsified in a solution of a soluble modification of cellulose, for example in crude or purified viscose or in a solution of cellulose, for example in cuprammonia, by known. methods, such as by injection, blowing, beating, agitation or the like; or the gas may be dissolved in the viscose or other solution with the aid of pressure.
  • Another method of operating consists in incorporating with the viscose or solution of cellulose a substance, for example an alkali carbonate, which is capable of evolving gas during the treatment for decomposing the viscose or precipitating the cellulose with an agent suitable for the regeneration or precipitation of the viscose respectively.
  • a substance for example an alkali carbonate
  • viscose containing gas or a substance capable of yielding gas is then applied to or incorporated with a fabric or yarn, by hand, or by means of a suitable machine.
  • this operation may, if desired, be conducted under reduced pressure, or under a raised pressure.
  • There may be added to the viscose or cellulose solution another coating or sizing agent, for
  • starch starch, dextrin, albumen or gelatin a softening agent, for instance, glycerine,
  • soap Turkey-red oil, glucose, castor oil, or parafiin oil
  • a filling material for instance, talc or china clay
  • a pigment for instance, zinc white, soot, or powdered mica
  • a dyestufi' or any two or more of these substances.
  • the cellulose may be regenerated from the viscose or precipitated from 'the cellulose solution in any known manner, by a suitable precipitating bath, or by other means, for instance, by heating, steaming, or merely by allowing the treated material to stand.
  • the gas for example air
  • the gas may be removed for example by boiling with water, or by. treatment with water under pressure. If the gas contained in the spaces is carbon dioxide, it maybe dis solved partly in the precipitating bath, and partly during the subsequent washing operation.
  • Example 1 Air is injected into a viscose, made 1n any desired manner from matured or non-matured alkali-cellulose containing I about 5-7 per cent. ofcellulose on analysis, so as to produce an emulsion.
  • a cotton fabric is dressed in known manner in a backfilling machine with the emulsion so produced, and the dressed material-is treated,
  • Example 2.-Theprocedi1re is as in Example 1, but with the exception that tale is added to the viscose in quantity amounting to about 23 parts for each part of cellulose as determined by analysis.
  • a suitable cotton fabric is dressed one or more times in a back-filling machine with the viscose produced in the manner just described, afterit has been filteredor strained, and in the freshly prepared state, or after it has aged for 18-96 hours at 15 C.
  • the dressed material is then immediately or after having been dried, then introducedinto sulphuric acid of 10 per cent. strength, or into any other acid precipitating bath known in the viscose industry, and dried.
  • the material may be desulphurized or bleached in any known manner (for example by means after which it is washed f of a solution of sodium sulphide) before or after it has been dried.
  • Emample 6 The procedure is as in Exits ample 3, Example 4 or Example 5,with' the exception that there about 1-2 per cent. of or castor oil.
  • sodium carbonate being neglected. There may, however, be used a viscose containing a smaller proportion of cellulose, for example, 45 per cent.
  • fibrous material in the specification and claims includes.wherever thecontext permits, any spun or woven fibrous material, whether animal or vegetable (for example, flax, linen,. hemp, ramie, jute, wool, and particularly cotton) in the form of pure fabrics or in the form of mixed fabrics, or in the form of yarn in skeins, cops or warps.
  • animal or vegetable for example, flax, linen,. hemp, ramie, jute, wool, and particularly cotton
  • cellulose means in the description and claims: cellulose and its near conversion products, such as cellulose hydrate, hydrocellulose and oxycellulose.
  • precipitated cellulose in the following claims includes wherever the context permits,"regenerated cellulose.
