Definitions

  • This invention relates to the treatment of yarns containing vegetable fibres, such as cellulose, that are readily carbonizable by certain carbonization processes and fibres or threads of a material, such as organic esters of cellulose, silk or wool that are not readily carbonizable by such processes, whereby novel effects are obtained.
  • An object of our invention is to produce novel effects with textile materials containing mixtures of materials that are readily corbonizable by a given process, and materials that are not readily carbonizable by such process by wholly or partially carbonizing the readily carbonizable material.
  • Another object of our invention is to produce novel spun yarn by subj ectin a mixed spun yarn containing a readily car onizablefibre, such as cellulose, and short lengths of filaments made of organic derivatives of cellulose, that are not readily carbonized by the same method, to a carbonizing treatment, either locally or throughout, whereby satisfactory spun yarn is produced.
  • a readily car onizablefibre such as cellulose
  • short lengths of filaments made of organic derivatives of cellulose that are not readily carbonized by the same method
  • the readily carbonizable fibres employed in our invention are vegetable fibres such as cotton or flax or fibres-of reconstituted cellulose.
  • the yarns, threads or fibres of material that is not readily carbonized by the subsequent treatment may comprise animal fibres such at natural silk or wool, but we prefer to employ organic derivatives of cellulose.
  • organic derivatives of cellulose are organic esters of cellulose such as cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate or cellulose ethers such as methyl cellulose, ethyl cellulose and benzyl cellulose.
  • any suitable carbonizing agent may be used.
  • the carbonizing agents that are suitable for use when an organic derivative of cellulose is present or when animal fibres are present in the textile materials, are solutions of aluminum chloride or hydrochloric acid of suitable concentration; while if animal fibres such as natural silk or wool are the only carbonization-resistant fibres present, stronger carbonizing agents such as sulphuric acid or the acid sulfates of sodium or potassium may be employed.
  • the carbonizing solution may be employed as such, and may be applied to the textile material by dipping, immersion, padding or spraying.
  • the carbonizing solution may be employed in admixture with a thickening agent such as starch, dextrine, British gum, gum tragacanth, etc. and applied in the form of a paste locally in any desired pattern, or over the entire surface of the yarn.
  • the textile material After the textile material has been treated with the composition of matter containing the carbonizing solution, it is heated to elevated temperatures, say 110 C. to 120 C. for a sufiicient period of time to carbonize the vegetable or cellulosic material, after which the carbonized material is removed by brushing or washing.
  • One application of our invention is for the preparation of spun yarns-made of organic derivatives of cellulose.
  • Organic derivatives of cellulose yarns are made from solu tions of the organic derivatives of cellulose by extrusion of the solutions through fine orifices and the removal of the solvent from 3 the filaments thus formed. Since the filaments are formed continuously, the yarns formed therefrom are of continuous length. Often it is desirable to prepare yarns of these materials that comprises short lengths of such filaments or yarns that are spun together. However, because of the lack of cohesion between yarns of cellulose acetate, it is not possible to prepare satisfactory spun yarns unless fibres of other materials are associated with the short lengths of the cellulose acetate yarn.
  • spun yarns consisting wholly of cellulose acetate staples may be prepared by spinning a mixture of the short cellulose acetate staples and vegetable fibres such as cotton,reconstituted cellulose, etc., to form a yarn, and then subjecting the mixed yarn to a carbonization treatment as herein described to remove the vegetable fibres, thus leaving a spun yarn consisting Wholly of short staples of cellulose acetate fibres.
  • some animal fibres, such as silk or wool may be mixed with the cellulose acetate and cotton fibres, and since they are unaffected by the carbonization treatment, a yarn comprising cellulose acetate fibres and animal fibres will remain.
  • the textile material may be dyed, bleached, etc., either before or after the carbonization treatment, in any suitable manner as is well understood in the art. If it is desired to prevent delustering of the yarn containing the organic derivatives of cellulose, deluster-preventing salts such as Glaubers salt or any of the deluster-preventing salts mentioned in U. S. Patent No.
  • Ewample A spun yarn containing short filaments of cellulose acetate. which are resistant to carbonization, and of cheap cotton. or re constituted cellulose fibre. which is easily .carbonized. is selected.
  • This yarn is immersed in the form of hanks in a bath contaming a solution of aluminum chloride of 6 to 13 Be. at ordinary room temperature.
  • the excess of aluminum chloride solution is then removed by pressing. squeezing. or bydroextraction. etc.. and the yarn is then placed in a carbonized dryer and treated at a temperature of 110 to 115 C. for from 1 to 1 ,4; hours.
  • the yarn is then removed from the drver and is brushed or washed, whereupon the carbonized cotton is removed. Since the cellulose acetate yarn is unaffected, a spun yarn consisting wholly of cellulose acetate fibres is produced.
  • the processof producing spun yarn containing organic derivatives of cellulose comprising spinning short lengths of organic derivatives of cellulose yarn with vegetable fibres and then carbonizing the vege table fibres out of the mixed spun yarn.
