8 Claims. 1
This invention relates to novel composite yarns and to methods of making them. The invention provides yarns which can be used in the construction of special effect fabrics of the ratin or boucl type by ordinary weaving procedures. The yarns may have only the normal or conventional twist of from one to five turns of twist per inch, or they may have a higher twist if desired.
An object of this invention is to provide composite yarns which may be woven to produce boucl or similar fabrics by ordinary weaving methods and without requiring the application of difierent degrees of tension to the yarns as they are fed to the loom. Another object of the invention is to provide yarns for making fabrics having surface characteristics which closely approximate or duplicate'those or" a boucl fabric. A specific object of the invention is to provide novel composite yarns comprising at least two singles yarns, at least one of which comprises regenerated cellulose fibers from viscose, and at least another of which is a singles yarn consisting of fibers of cellulose reconstituted from an organic acid ester of cellulose in situ in the yarn.
The objects of the invention are accomplished in the following manner:
A composite yarn is produced by plying, doubling or otherwise associating at least one singles yarn formed of fibers of a fiber-forming organic acid ester of cellulose with at least one singles yarn formed of fibers of a fiber-forming material which is not affected, as such,by aqueous solutions of ammonia or lower alkylene amines. Preferably the yarns which are associated to form the composite yarn have a twist of from one to five turns of twist per inch. The composite yarn is then immersed in an aqueous solution of ammonia or of an alkylene amine, such as methylenediamine or ethylene-cliamine, to effect com plete deesterificaticn of the cellulose organic acid ester component throughout its cross-section, the conditions of the deesterification being such that the final composite yarn does not have a measurable cellulose ester content. The composite yarn is then dried in relaxed condition.
The component comprising the cellulose organic acid ester may comprise one or more singles yarns formed from fibers or filaments of cellulose acetate, propionate, butyrate, etc... or it may comprise one or more singles yarns formed from fibers or filaments of mixed cellulose esters, such as cellulose acetate-butyrate.
The expression singles yarn designates a continuous fibrous strand consisting of a multiplicity of fibers and/or filaments associated tomeasurements on the cellulose. Deesterification of the cellulose ester component without'degradation of the cellulose is essential to the produc tion of useful, stable composite yarns having the desired characteristics. The cellulose ester component present in the composite yarn in its initial condition, exists in the finished yarn as a component of cellulose reconstituted from the ester.
As a result of the removal of the ester groups:
from the cellulose chain, the reconstituted cellulose component undergoes linear shrinkage so:
that when the treated composite yarn is dried in the relaxed state, the reconstituted cellulose component expends its shrinkage capacity, and shrinks linearly causing the remaining component of the yarn which is not afiected as such by the deesterification treatment to wind itself about the reconstituted cellulose component. There is thus obtained a composite yarn in which the component other than the reconstituted cellulose component has been converted to a permanently crimped condition, thereby crimping the composite yarn as a whole.
The deesterification of the cellulose ester component of the composite yarn must be homogeneous andcomplete and, as has been stated, the composite yarn, after the deesterification treatment, must not have a measurable cellulose ester content. I find that ammonia and the lower alkylene amines having up to 3 carbons are specific agents for deesterifying the cellulose ester component homogeneously throughout its cross-section without appreciable. or noticeable degradation of the cellulose. The conditions of the treatment, that is the concentration of the nitrogeneous deesterifying agent, the temperature at which the composite yarn is treated with the solution, and the duration of the treatment, are interrelated. If lower concentrations." of ammonia or alkylene amine are used, higher. temperatures and longer immersion times are necessary, and vice versa. However, the deesterifying medium is maintained in the liquid phase throughout the entire treatment. I prefer to use aqueous solutions of ammonia or the alkylene amines of from 6 to 28% concentration at room temperatures, that is at temperatures in the range of to 30 0. Under those conditions, the deesterification is complete in from 6 to 15 hours. Preferably, the treated composite yarn is dried in the relaxed state at from 90 to 95 C.
The singles yarn or yarns plied or otherwise associated with the singles yarn or yarns of the fiber-forming organic acid ester of cellulose may be formed from fibers or filaments of any fiberforming material which is not afiected, as such, to any appreciable extent when the composite yarn is dried in the relaxed condition after immersion in the solution of ammonia or alkylene amine used to convert the cellulose ester component to reconstituted cellulose. For example, the singles yarn associated with the cellulose ester yarn may comprise silk, cotton, flax, regenerated cellulose from viscose or cuprammonium, etc.
The composite yarn comprising a component of cellulose reconstituted from the ester may be woven to produce boucle' or ratin fabrics having efiects corresponding to those of fabrics made from the conventional houcl yarns comprising two ground threads and an effect thread. How ever, the usual special weaving procedures normally resorted to in the manufacture of boucl fabrics are not necessary in. the present case. The boucl efiects are due solely to the presence of the novel composite yarns of the invention. The fabrics may be made wholly of the new composite yarns comprising the component of cellulose reconstituted from an ester in situ in the yarn, or the composite yarns may alternate with plain yarns in the warp and filling, or in the filling only. The new composite yarns may also be knitted to produce fabrics having very interesting surface characteristics.
The following examples will illustrate the method of the invention:
Example I A plied yarn was formed from a 150 denier/ 90 filament dull viscose yarn having a twist of 3 8 turns of twist per inch, and a 150 denier/41 filament dull cellulose acetate yarn (commercial secondary acetate) having a twist of 3 8 turns of twist per inch. The plied yarn had a Z twist of 8 turns per inch. The plied yarn was immersed in skein form in a bath consisting of a 15% aqueous ammonia solution for 15 hours at room temperature. The yarn was then washed free of ammonia, given a soft soap finish, and dried in the relaxed condition. Immersion of the yarn in the ammonia solution had the efiect of converting the cellulose acetate component to reconstituted cellulose at all portions of its crosssection, so that when the yarn was dried while relaxed the component which initially comprised cellulose acetate shrank about 40% in linear dimension, causing the component of regenerated cellulose from viscose to wind itself about the shrunken component.
The composite yarn was woven as a filling for a fabric, the warp yarns of which consisted of one end of 150 denier/90 filament dull viscose rayon yarn having 3 8 turns of twist per inch, alternating regularly with one end of 150 denier/41 filament dull cellulose acetate yarn having 3 8 turns of twist per inch.
Example II A composite yarn consisting of one end of 200 denier/52 filament dull acetate yarn having 3 turns of twist/inch and one end of 150 denier/ filament dull viscose yarn having 3 turns of twist/inch, plied to give a composite yarn having 14 8 turns per inch, and treated as in Example I to convert the cellulose acetate to reconstituted cellulose was used as filling for a woven fabric, the warp of which comprised one end of 75 denier/30 filament bright viscose rayon yarn having a twist of 3 8 turns of twist/inch alternating regularly with one end having three Z turns of twist/inch. A novel fabric having thick and thin surface characteristics was produced.
Example I II A composite yarn was obtained in the following manner: A denier/36 filament dull acetate yarn having 1 /2 8 turns of twist/inch was plied with a 75 denier/30 filament bright viscose rayon yarn having 3 S turns of twist/inch, to give a plied yarn having 14. 8 turns of twist/inch. Two of these plied yarns were plied to give a composite yarn having 8 2 turns of twist/inch. The composite yarn was treated as in Example I to convert the cellulose acetate yarn to reconstituted cellulose. The composite yarn was then used as the filling for a fabric having a warp as in Example II. A novel fabric having thick and thin surface characteristics was obtained.
Some variations maybe made in the conditions specifically stated in the examples without transcending the spirit and scope of the invention as defined in the appended claims.
