- ATTORNEY 8 AGENT United States Patent 3,414,957 PROCESS FOR DYEING TEXTILE FIBERS AND PREPARING HIGH-BULK FABRICS Witt I. Langstalf and Thomas L. Shealy, .Ir., Kingsport,
- This invention relates to dyeing textile fibers, particularly acrylic textile fibers and to the preparation of highbulk yarn and fabrics.
- the process has several disadvantages residing partly in the fact that since dyeing is carried out after the yarn is prepared, the yarns are obtained only in single colors. Yarns containing blends of different colors are thus not obtainable. Also, since many types of fiber such as polyester and acrylic fibers cannot be successfully dyed together and since the high-shrink fiber cannot be dyed prior to blending, it has not been possible to make highbulk blend yarns of this type.
- tow dyed material such as acrylic tow
- the dyed fibers may gradually lose their heat-shrink property on natural aging at temperatures common in warehouses and knitting mills. More particularly, the processing of towdyed fiber has been unsatisfactory in yarn making. The process also has limitations in dyeing method.
- a common method of dyeing nonbulky yarns is to wind the yarn on perforated tubes and dye the resulting packages by forcing dye liquor through them. This operation is less expensive than skein dyeing, in which the yarn must be wound onto skeins and tied with strings before dyeing. It has not been possible to dye high-bulk yarns by, the package dyeing process since at temperatures normally used, the shrinkable fiber undergoesshrinkage and .the resulting yarn can no longer be bulked.
- fibers composed of hydrophobic; synthetic fiber-forming polymers, particularly acrylic and modacrylic polymers, modified so as to be dyeableat low temperatures, can be treated to impart heat shrinkage properties thereto, for example by drafting and cooling the fibers without relaxing, and the heat-shrinkable fibers can be dyed alone or combined in a composite yarn with the heat-stable fibers, for example in package form, at a temperature below that causing the fibers to shrink; thus, dyeing can be carried out at temperatures below 160 F., preferably between 140 F. and 160 F. Subsequent drying of the fibers should also be carried out at temperatures below that causing loss of heat shrinkage, for example at about 180 F. to 220 F.
- the lean composite yarns thus obtained containing heat-shrinkable and heat-stable fibers are susceptible to heat treatment to produce high-bulk fabrics.
- the staple heat-shrinkable and heat-stable fibers may be combined in the desired system such as the cotton systern employing the usual picking, carding, drawing, roving and spinning operations.
- the staple heat-shrinkable 3,414,957 Patented Dec. 10, 1968 fiber may first be dyed and dried at temperatures below which shrinkage occurs before combining with the heatstable fibers into yarn in the cotton system. Otherwise, the yarn containing colorless heat-shrinkable fiber and heatstable fibers can be package or skein dyed before forming into fabric as by knitting or weaving after which the fabric is heated to give high bulk.
- slivers of dyed or undyed heat-shrinkable fibers can be blended with slivers of heat-stable fiber by known methods to produce the heat-shrinkable yarn. While the yarn comprising heatshrinkable and heat-stable fiber is primarily designed for dyeing at low temperature especially prior to fabrication, the fabric or garment can be dyed at the low temperature followed by bulking with heat or dyeing and bulking of the fabric can be carried out at one time by dyeing at the boil.
- the dyeing of the lean yarns from the spinners containing a mixture of colorless heatshrinkable and heat-stable fibers may not dye the heat-stable fibers since they may be dyeable only at higher temperatures.
- fabrics containing the partially dyed yarn are pleasing in appearance. Accordingly, if desirable, the dye heat-shrinkable fibers can be combined with heat-stable fibers which have been dyed as usual at the boil and the two types of fibers spun into a lean yarn susceptible to bulking by means of heat.
- different deniers of the heat-stable and heat-shrinkable fibers can be, e.g., ranging from about 1 to 16 denier. In some cases, it may be desirable to use substantially different deniers for e two types of fibers to obtain the desired result.
- Representative synthetic hydrophobic fiber-forming polymers susceptible to such treatment to impart the high heat-shrinkage property thereto and which, in the shrinkable form, can be expected to be readily dyeable without substantial loss of shrinkage are, for example, acrylonitrile homopolymers and copolymers including acrylonitrilevinyl halide copolymers and acrylonitrile-vinylidene halide copolymers, which fiber-forming polymers have been modified to improve their dyeability by blending or otherwise incorporating into the polymer alkylacrylamide polymers such as poly-N-alkylacrylamides, acrylic ester polymers including polyethylacrylate and polymethylmethacrylate, polyvinylpyridines, poly(vinylpyrrolidones), polyvinyl acetals, e.g.
- polyvinylbutyral epoxy resins, e.g. epichlorohydrin-sulfide or epichlorohydrinbisphenol condensates, polyalkylimines, polycarbonates, pollyoxyalkenes, divalent metal salts of aliphatic carboxylic acids, metal sulfonates, etc.
- epoxy resins e.g. epichlorohydrin-sulfide or epichlorohydrinbisphenol condensates
- polyalkylimines polycarbonates
- pollyoxyalkenes divalent metal salts of aliphatic carboxylic acids, metal sulfonates, etc.
- the polymers can be expected! to lose no more than about 2 to 10% of their heat-shrinkage property, and dyed fibers and yarns are readily obtainable possessing as much as 30 to 40% retained shrinkage.
- the shrinkage of the fiber before or after dyeing is determined by placing a given length in boiling water for two minutes followed by quenching with cold water and measuring the change in length. More accurate results are obtained using samples of tow in the test prior to cutting it into short staple fiber lengths.
- Yarn shrinkage is determined similarly except that the measurements of length of yarn before and after heating in water is made with a standard amount of tension per denier on the sample of yarn. Accordingly, by heatshrinkable fiber or yarn, we mean the fiber or yarn capable of about 20% or more shrinkage on heating to elevated temperatures.
- An especially useful group of polymers to which substantial heat-shrinkage can be imparted which is retained on dyeing at relatively low temperatures, are the acrylonitrile polymers and copolymers preferably containing at least about 35% combined acrylonitrile units and up to about 95% acrylonitrile units, and modified, so as to be dyeable at low temperatures without substantial loss of shrinkage while retaining good dye fastness, for example, by 85-5 of vinyl pyridine units as described in U.S. Patents 2,990,393 (Re. 25,533) and 3,014,008 (Re. 25,539) or modified by 655% of vinylpyrrolidone units, for example as described by U.S.
- Patent 2,790,783 or modified with 655% acrylic ester or acrylamide units as described in U.S. Patents 2,879,253, 2,879,254 and 2,838,- 470. Similar amounts of the other polymeric modifiers mentioned above are also useful. The polymers will thus retain a useful amount of shrinkage under conditions that lead to significant dyeing of the fibers.
- a typical copolymer composition can be prepared as follows: 93 parts of acrylonitrile, 7 parts of 2-vinylpyridine, 1500 parts of water, 1.5 parts of ammonium persulfate, 1.5 parts of sodium metabisulfite, 10 parts of phosphoric acid, and 2.0 parts of sodium lauryl sulfate were heated at 40 C. for hr.
- the resultant polymeric slurry which had an intrinsic viscosity in dimethyl formamide of 1.4, was washed and dried, and after solution in dimethylformamide, was spun under conditions that gave a fiber having an appreciable degree of residual shrink.
- This material could be dyed under conditions that gave a dyed fiber that still retained about 70% of its original shrinkage.
- a preferred group of copolymers especially adapted to treatment to impart high heat-shrinkage property to fibers thereof and which are readily dyeable at low temperatures without appreciable loss of their shrinkage characteristics are the modacrylic polymers such as described in U.S. Patent 2,831,826 composed of a mixture of (A) 70-95% by weight of a copolymer from 30 to 65% by weight of vinylidene chloride or vinyl chloride and 7035% by Weight of acrylonitrile, and (B) 305% by weight of a second polymer from the group consisting of (1) homopolymers of acrylarnidic monomers of the formula wherein R is selected from the group consisting of hydrogen and methyl, and R and R are selected from the group :onsisting of hydrogen and alkyl groups of 1-6 carbon atoms, (2) copolymers consisting of at least two of said acrylamidic monomers, and (3) copolymers consisting at at least 50% by weight of at least one of said acrylimidic monomers and not more than 50% by weight of
- a particularly efiicacious group of modacrylic polyners for use in the low temperature dyeing process of the ,nvention is an acetone soluble mixture of (A) 7095% W weight of a copolymer of 30-65% by weight of vinyldene chloride and 70-35% by weight of acrylonitrile and 1B) 305% by weight of an acrylamide homopolymer iaving the above formula wherein R R and R are as lescribed above.
- Specific polymers of that group contain 095% by weight of (A) a copolymer of from 30-65% y weight of vinylidene chloride and 70-35 by weight of tcrylonitrile and (B) 30-5 by weight of a lower N -alkyltcrylamide polymer such as poly-N-methylacrylamide, Ioly-N-isopropylacrylamide and poly-N-tertiarybutylacryltmide. It is polymers such as these which in heat-shrinktble form have the unique properties of dyeing to strong hades at relatively low temperatures such as below 160 without losing their heat-shrinkage properties.
- the colored heat-shrinkable fibers described can then e combined into a yarn together with the heat-stable Inonshrinkable) textile fibers and after forming into a abric, for example by knitting or weaving, heat can be tpplied to differentially shrink the fibers to produce a tigh-bulk fabric.
- the method of applying heat to the abric to shrink the fibers is not critical, for example, hot it at a temperature not adversely affecting the fibers of he order of 250-300 F. can be applied.
- the increase in bulk is readily apparent from counting the increase in the number of courses and wales per inch and noting the increase in the weight of fabric per square yard. The improved fullness of hand will also be apparent.
- the combination of the specified shrinkable fibers and low temperature dyeing produces fibers whose heatshrink properties are maintained on natural aging under room conditions over an extended period of time.
- the heat-stable fibers which are used in the high-bulk fabrics together with the shrinkable fibers include a wide variety of fibers such as cotton, mohair, wool, viscose, heat-stable acrylonitrile homopolymers and copolymers such as those sold under the names Creslan, Acrilan, Dynel, Zefran, Orlon, the linear terephthalate polyesters such as the linear cyclohexane-1,4-dimethanol terephthalate polyesters described in the Kibler et al. U.S. Patent 2,901,466, granted Aug. 25, 1959, which have been heat stabilized as described in the patent.
- the heat-stabilized glycol terephthalate polyesters including polyethylene terephthalate, described in the Whinfield et al. U.S. Patent 2,465,319, granted Mar. 22, 1949, are also very useful as the heat-stable component of the high-pile fabric.
- the dyes are particularly useful for dyeing the heatshrinkable fibers, particularly the mod-acrylic fibers described above include the cationic or basic dyes well known in the art for dyeing acrylic fibers, for example the Basacryl series of cationic dyes which are usually used for dyeing acrylonitrile polymers such as Acrilan and Dynel at the boil, for example: Basacryl Yellow 5RL (Cl. Basic Yellow 25), Basacryl Red 'GL (C.I. Basic Red 29), Basacryl Blue 3RL (01. Basic Blue 53) and Basacryl Blue GL (C.I. Basic Blue 54).
- Basacryl Yellow 5RL Cl. Basic Yellow 25
- Basacryl Red 'GL C.I. Basic Red 29
- Basacryl Blue 3RL 01. Basic Blue 53
- Basacryl Blue GL C.I. Basic Blue 54
- the Sevron series of dyes also represent cationic dyes useful in the process and include, for example, the cationic cyanine, methine, anthraquinone, oxazine and triphenylmethane dyes such as Sevron Yellow L (0.1. Basic Yellow 13), Sevron Yellow R (0.1. Basic Yellow 11), Sevron Orange G (C.I. Basic Orange 21), Sevron Blue B (C.I. Basic Blue 21), Sevron Blue 2G (C.I. Basic Blue 22), Sevron Blue 5G (C.I. Basic Blue 4), Sevron Brilliant Red 4G (0.1. Basic Red 14) and Sevron Green B (C.I. Basic Green 3).
- the cationic cyanine, methine, anthraquinone, oxazine and triphenylmethane dyes such as Sevron Yellow L (0.1. Basic Yellow 13), Sevron Yellow R (0.1. Basic Yellow 11), Sevron Orange G (C.I. Basic Orange 21), Sevro

- Cibalan Orange RL C.I. Acid Orange 88
- Cibalan Blue BL C.I. Acid Blue 168
- Cibalan Brown ZGL no CI. number
- Cibalan Grey 2GL C.I. Acid Black 62.
- Dyeing assistants and leveling agents such as nonionic surfactants and phosphate compounds are useful as shown in the following examples.
- Methods known in the art can be used for imparting the heat-shrink properties to the fibers such as the modacrylic fibers of U.S. Patent 2,831,826 described above. These methods include spinning the modacrylic fibers from solvent, passing the tow bundle over heated rolls and drafting the fibers to about 3-6 times their original length at a temperature of about 250-400 F. followed by cooling the fibers without relaxing or further heat treatment.
- a particularly useful method for imparting heat-shrinkage to the modacrylic fibers of the above patent include drafting the fibers at a temperature of the order of 250300 F. and spraying the fibers with chilled water or passing them over a cool roll without relaxing or further heat treatment. When fibers such as the above modacrylic fibers are to be utilized as the heat-stable component of the high-bulk fabric, they are drafted with heat and relaxed and heat-stabilized in accordance with the usual practice.
- Stage 2 the same yarn is shown diagrammatically substantially as it would appear after heating to cause differential shrinkage of the fibers and thus bulking of the yarn.
- a modacrylic fiber was prepared as described in US. Patent 2,831,826 comprising a mixture of a icopolymer of vinylidene chloride and acrylonitrile and a minor amount of a poly(lower N-alkylacrylamide), the fiber being drafted with heat and cooled without relaxing to impart high heat-shrinkage thereto, after which the tow was cut to staple length.
- Fifty pounds of this 3 d./f., l /f'length bright luster high shrinkage modacrylic staple fiber was dyed a medium brown shade in a Riggs and Lombard stock dyeing machine. The machine was filled to three-quarters capacity with water at 80 F. The fiber was loaded into the water by hand and distributed evenly. The machine was filled to the correct volume with water and circulation of the water was begun. The following chemicals were added to the machine and circulated for minutes.
- the following dyes based on the fiber weight were pasted with acetic acid and dissolved in water, then added to the dye machine and circulated for 10 minutes.
- the dye bath temperature was raised from 80 F. to 140 F. over a period of 45 minutes.
- the fiber was dyed 60 minutes at 140 F. then rinsed at 120 F., removed from the machine and the water extracted in centrifuge. The fiber was then dried at 190 F.
- This yarn was knit into a fabric on a Dubied NHF-S V-bed knitter. It was knit from two cones of yarn. The greige'fabrie contained 6.5 courses/inch and 6 wales/ inch and weighed about 7 ounces per square yard.
- the grei ge fabric was then placed in a boiling water bath for 20 minutes. It was removed and tumble dried at 220 F.
- the fabric showed a remarkable degree of bulking as evidenced by the change in construction to values of 10 courses/inch and 9 wales per inch and an increased weight to about 10 ounces per square yard.
- the fullness of hand of the finished fabric was remarkably improved as compared to the greige as-knit fabric.
- the finished fabric also had much improved cover.
- the bulking potential of the yarn is not lost with age. This is shown by testing the contraction or shrinkage in length of the yarn over a period of time, illustrated by the following data obtained for a yarn similar to that used in the above example.
- the dyed shrinkable fiber or a yarn or fabric containing it can be shipped or stored for significant periods of time before it is bulked without loss of bulking potential. This is of considerably advantage as often the fiber is dyed in one plant, spun into yarn in a second plant, knit into fabric in a third plant and made into a garment in a fourth plant and the final finishing of the garment may thus take place some time after the shrinking fiber is dyed.
- the heat-stable polyester fiber was not dyed, it can be stock dyed to any desired shade for cross dye or heather effects. Or, if desired, two or more yarns can be made from different colored stock dyed or natural staple fibers and used in knitting to produce bulky knit garments having stripe and other pattern color effects as desired.
- a natural yarn and a colored yarn can be knit together into a fabric and bulked to produce a color and whitestriped or patterned sweater or dress at low cost.
- Example II Example I was repeated using a heat-stable polyethylene terepthalate polyester fiber as the nonshrinking component in a blend with the shrinkable modacrylic fiber. A similar improvement in the bulk, hand and cover of the finished fabric was noted.
- Example I was repeated using a heat-stable unmodified acrylonitrile polymer staple fiber as the non-shrinking fiber component of the blend. When the knit fabric was finished, the same improvement in bulk found in Example I was noted.
- EXAMPLE IV A blend yarn was spun from 40% of the 3 d./f., 2 /2 shrinkable modacrylic staple fiber and 60% of a cyclohexane-1,4-dimethanol terephthalate polyester staple fiber of 4.5 d./f. and 2 /2 length. Both fibers were bright luster. The yarn was spun on the cotton system into a 20/2 cotton count size yarn.
- the yarn was package dyed according to the following procedure:
- the ability of the yarn of the invention represented by this example, to be bulked after package dyeing is unique.
- Example IV was repeated except that the yarn was skein dyed according to the following procedure:
- the skein dyed yarn was knit into fabric and bulked with good results as in Example IV.
- Example IV was repeated except that polyethylene ter- :phthalate heat-stable fiber was substituted for the heat- ;table polyester yarn of Example IV.
- the yarn was packtge dyed, knit, and bulked by steaming. A similar improvement in the bulk of the finished fabric was noted.
- Example VII Example IV was repeated except that an unmodified acylonitrile polymer fiber was used as the heat-stable com- )onent of the blend.
- the knit fabric made from the package dyed yarn was steam treated to shrink the modacrylic component and a remarkable improvement in bulk was noted.
- Example IV was repeated except that an apparel grade wool fiber was substituted for the heat-stable polyester fiber. Similar results were obtained as in Example IV.
- Example IV was also repeated using cotton fiber in place of the heat-stable polyester fiber. Similar results were obtained as in Example IV.
- the package dyed unbulked yarn can be woven into a loose weave fabric.
- the fabric is then treated with steam or boiling in a relaxed state so that the dyed shrinking component can cause contraction and a resultant bulking of the fabric to give it improved fullness of hand, thickness, heat insulation ability and bulk.
- the fabric can be woven from alternate multiple picks and Warp ends of a potentially shrinkable dyed yarn and a non-shrinkable dyed yarn. When such a fabric is then steamed or treated in hot water, a popcorn or wafiie texture woven fabric is obtained.
- heat-stable polyethylene terephthalate polyester has 2.8% shrinkage in boiling Water and 11.2% shrinkage in 190 C. hot air and some heat-stable acrylic fibers may have 3% or more shrinkage in boiling water and up to 20% shrinkage in 190 C. hot air.
- the bulking of a yarn composed of shrinking and non-shrinking fibers is based on the difference in potential shrinkage at a given temperature, it can be seen that with the same shrinkable fiber, the cyclohexane-1,4-dimethanol terephthalate polyester fiber will make it possible to achieve higher bulk levels than other less heat-stable fibers which have higher shrinkage values in hot water or air.
- EXAMPLE X A staple yarn was spun from a blend of 40% of shrinkable modacrylic fiber such as used in Example I, 3 d./f., 2 /2 cut, bright luster fiber and 60% of a cyclohexane- 1,4-dimethanol terephthalate polyester staple fiber of 4.5 d./f. and 2% cut of bright luster.
- the yarn was of a 14/ 2 ply cotton count construction.
- the yarn was knit into a fabric containing 6.5 courses/ inch and 6 wales/inch.
- the greige fabric was then dyed and bulked by the following procedure.
- the dyed and bulked fabric exhibited good bulk, fullness of hand and cover. It contained 12 courses/inch and 9 wales/ in ch.
- Example X was repeated using in one case heat-stable acrylonitrile polymer fiber and in one case a heat-stable polyethylene terephthalate fiber in place of the heat-stable polyester of Example X. Similar bulking results were obtained.
- EXAMPLE XII A blend of 50% 3 d./f., 2 /2 bright shrinkable modacrylic fiber of Example I and 50% of the same fiber but nonshrinkable 16 d./f., 2 /2 bright fiber was spun into an 8/1 yarn and knit on a Tompkins circular knit machine into a fiat knit fabricof about 28 ounces per square yard. Using low temperature dyeing techniques, the fabric was dyed according to .the following procedure:
- the fabric was rinsed and after treated with a cationic softener for 20 minutes at 120 F. To remove excess water, the fabric was vacuum extracted and dried at 190 F. The fabric was then passed through the normal pile fabric finishing operation of napping, shearing and heating at 280 to 300 F. to shrink the shrinkable fiber and provide a 2-pile height effect. The pile of the fabric was then heat-polished and an imitation fur fabric resulted.
- thermoshrinkable fibers imparted heat-shrinkage include a mixture of (A) 70-95% by weight of a copolymer of from 30 to 65% by weight of a member of; the class consisting of vinyl chloride and vinylidene chloride and 70 to 35% by weight of acrylonitrile, and (B) 30-5% by weight of a second polymer from the group consisting of (1) homopolymers of acrylamidic monomers of the formula wherein R is selected from the group consisting of hydrogen and methyl, and Rgand R are selected from the group consisting of hydrogen and alkyl groups of 1-6 carbon atoms, (2) copolymers consisting of at least two of said acrylamidic monomers, and (3) copolymers consisting of at least 50% byweight of at least one of said acrylamidic monomers and not more than 50% by weight of a polymerizable monovinyl pyridine monomer, dyed at a temperature below that causing the fibers to shrink.
