Description

United States Patent ABSTRACT OF THE DISCLOSURE An aqueous textile finish composition, particularly adapted for the prevention of gas fading or yellowing on age of spandex blend fabrics comprising from 0.1 to 10 parts by weight of a hydrolyzed vinyl ether-maleic anhydride copolymer, from 1 to 20 parts by weight of a thermosetting melamine type resin, from 0.2 to parts by weight of an acidic catalyst, from 0 to parts by weight of an acrylic latex, from O to 0.5 parts by weight of ammonium zirconyl carbonate, from 0 to 10 parts by weight of fabric softener selected from the group consisting of anionic and nonionic fabric softeners, and the remainder water.
The present invention relates to novel textile finish compositions; textile materials treated with said finish compositions and the method for treating the textile materials.
Many textiles are commonly impregnated with some material which imparts a desirable finish thereto. However, the problem of gas fading, whereby the textiles, for example, spandex blend fabrics, are discolored has continued to remain among the leading problems in the textile field. Gas fading of the textile is caused by nitrogen and sulfur oxides in the atmosphere. For example, under the influence of gas fumes, such as gas dryers, smog atmosphere, furnace or stove gases, the textile fiber turns progressively yellower.
In'order to overcome this problem, it has been proposed to use a hydrolyzed vinyl ether-maleic anhydride copolymer. While the use of a hydrolyzed vinyl ethermaleic anhydride copolymer with or without softeners, as a textile finishing agent contributed substantially to finished textiles, said finished textiles continued to have the serious failing of gas fading, since the hydrolyzed vinyl ether-maleic anhydride copolymer is easily removed by one or two home launderings leaving the textile susceptible to gas fading.
I have now discovered novel and unobvious textile finish compositions which may be used as gas fading inhibitors and which, when applied to textile materials will afford the finished textile materials with excellent protection to gas fading even after repeated washings.
It is among the objects of this invention to provide novel gas fading inhibiting textile finish compositions which comprise (1) a thermosetting methylolated melamine type resin such as a cross-linkable, thermosetting hydroxylated, alkylated, or hydroxyalkylated methylolated melamine resin; (2) a hydrolyzed vinyl ether-maleic anhydride copolymer, especially poly (vinyl-methyl ethermaleic anhydride), such as Gantrez AN-119 (r Sp. 0.1- 0.5), Gantrez AN-139 (1 Sp. 1.01.4), Gantrez AN-l49 (1; Sp. 1.5-2.0), Gantrez AN-l69 (1; Sp. 2.6-3.5), and the like; (3) an acidic catalyst, such as 2-amino-2-methyl- 1 propanol hydrochloride, 2 amino-methyl-l propanol phosphate, monoethanolamine hydrochloride, Z-amino-lbutanol phosphate, triethanolamine phosphate, diethanolamine hydrochloride, 1-amino-2-methyl-2-butanol phosphate, l-amino 2 methyl 2-butanol hydrochloride, 3-
amino-Z-methyl 2 butanol hydrochloride, diammonium phosphate, ammonium chloride, magnesium chloride, zinc chloride, oxalic acid, citric acid, zinc nitrate and the like and (4) the remainder water. Said novel textile finish compositions may also contain, if desired, one or more other ingredients like acrylic latices, such as methyl, ethyl, propyl, etc., esters of acrylic or methacrylic acids or amides, and the like such as Rhoplex HA-8, Rhoplex K-3, Rhoplex HA-l2, Rhoplex HA-l6, Rhoplex HA-20, Rhoplex E-32, each of these with or without oxalic acid as a rapid curing catalyst, Polectron 130, and other emulsion copolymers familiar to those in the textile trade as finishing agents, which function partially as binders and partially as fabric hand modifiers; ammonium zirconyl carbonate, which functions as an auxiliary binder and a wide variety of anionic or nonionic fabric softeners such as salts of carboxylated, sulfonated or sulfated compounds containing a long alkyl chain, polyoxyethylenated long chain active hydrogen compounds, fatty acid esters of mono, di, and polyhydride alcohols, long chain fatty acid amides, and the like, such as Emulphor VT-510, Soromine MG-lOO, Soromine N-SO, Soromine AL, Soromine AN-25, Blandofen SL, Avitex K, Ahcovel NC, Nopcotex 668, Profine Paste and Soromine AT.
The cross-linkable, thermosetting hydroxylated and hydroxy methylated melamine resins used in this invention may be the hydroxylated and hydroxyalkylated products produced by treating aminotriazines with formaldehyde or urea followed by treatment With a lower aliphatic alcohol as shown by U.S. Pat. 2,454,078, for example. Among the preferred resins used in this invention that may be mentioned are the cross-linkable thermosetting hydroxymethylated melamine resins, such as American Cyanamides Aerotex Resin M-3 and Aerotex Resin 23 Special and Monsantos Resloom M80.
Another object of this invention is to provide textile materials, such as glass fibers; celulose fabrics or fibers, i.e., cotton and rayon; polyester fabrics or fibers; polyamide fabrics or fibers, i.e., nylon; and particularly spandex (segmented polyurethane) blend fabrics, especially spandex blends which have been treated with the above mentioned novel textile finish compositions and the method of said treatment. Other objects of this invention will become more apparent as the disclosure proceeds.
The quantitative proportions in which the components are used in carrying out the invention may vary Within wide limits for the amounts present depend upon such conditions as the particular fabric or fiber being treated, the desired commercial finish, and the like. For example, the hydrolyzed vinly ether-maleic anhydride copolymer may be present in the range of about 0.2 to about 5.0 parts by weight; the thermosetting melamine type resin may be present in the range of about 1 to about 20 parts by weight; the acidic catalyst may be present in the range of about 0.2 to about 5.0 parts by weight; the optional ingredients such as the acrylic latices may be present in the range of 0 to about 8 parts by Weight; ammonium zirconyl carbonate may be present in the range of 0 to about 05 part by weight; and the softeners may be pres ent in the range of 0 to about 10 parts by weight. However, it has been found that exceptionally good finishes have been obtained when the hydrolyzed vinyl ethermaleic anhydride copolymer is present in the range of about 1.5 to about 3 parts by weight; the thermosetting resin is present in the range of about 2.5 to about 8 parts by weight; the acidic catalyst is present in the range of about 0.5 to about 1.4 parts by weight, the acrylic latices is present in the range of 0 to about 3.0 parts by weight; the ammonium zirconyl carbonate is present in the range of 0 to about 0.5 part by weight and the softeners are present in the range of O to about 3 parts by weight.
These novel textile impregnating compositions may be applied to textiles in the form of a solution, emulsion, or dispersion in water or some other inert liquid. It will be apparent that the solution employed for impregnating the fabric must not be too concentrated for viscous or an uneven finish may be obtained. On the other hand, the solution employed for impregnating the fabric must contain a suificient amount of the impregnating composition so that the fabric will pick up and retain a sufficient amount thereof to impart the desired finish thereto. The amount of impregnating composition which should be incorporated in the solution employed to impregnate the fabric in order that a suificient amount will be retained by the fabric to impart the desired finish thereto can readily be determined by simple preliminary experiments.
The instant novel textile finish compositions may be applied by any known conventional method such as by padding or the heated jig method, the preferred procedure being the padding operation.
The following examples are illustrative of the present invention and are not to be regarded as limitative. It is to be understood that all parts, percentages and proportions referred to herein and in the appended claims are by weight unless otherwise indicated.
EXAMPLE I A textile finish composition was prepared containing the following:
Percent Gantrez AN139, hydrolyzed 2.0 Aerolex Resin M-3 (a cross-linkable thermosetting hydroxymethylated melamine resin) 5.0 Catalyst X-4 (a zinc nitrate solution of Sun Chemical) 1.4 Emulphor VT-5l0 (a fatty acid ethoxylate softener) 1.0 Ammonium zirconyl carbonate solution 0.3
Water 90.3
A large piece of 30/70 bare Lycra/ nylon knitted fabric was padded with the above composition at about 60% wet pickup, air dried and cured for three minutes at 270275 F.
A portion of the treated fabric was then washed a series of six times at 120 F. in Tide solution, rinsed and dried. The washed and unwashed treated samples Were then exposed to one cycle of gas fading by the standard test described in AATCC STM-231962. The unwashed treated sample showed excellent resistance to gas fading while the treated sample which had been Washed six times exhibited only slightly more fading than the unwashed sample.
EXAMPLE II By way of comparison, Example I was repeated using an aqueous solution of 1.5% Gantrez AN-139 alone.
A textile finish composition was prepared containing the following:
Percent Gantrez AN139, hydrolyzed 1.5 Water 98.5
A large piece of 30/70 bare Lycra/nylon knitted fabric was padded with the above composition at about 60% wet pickup, air dried and cured for three minutes at 270-275 F.
A portion of the treated fabric was then washed 2. series of six times at 120 F. in Tide solution, rinsed and dried. The washed and unwashed treated samples Were then exposed to one cycle of gas fading by the standard test described in AATCC STM-23-1962. The unwashed treated sample showed excellent resistance to gas fading while the treated sample which had been washed six times exhibited pronounced yellowing after only one wash cycle and showed progressively more yellowing after the second and through the sixth washes.
4 EXAMPLE III Various pieces of 30/ 70 bare Lycra/ nylon knitted fabric were padded at about 60% wet pickup with the following textile finish compositions, air dried and cured for three minutes at 270 F. Portions of the various treated fabrics were washed three to six times at 120 F. in Tide solution, rinsed and dried. These portions of the treated and washed fabrics were then exposed to one cycle of gas fading by the standard test described in AATCC STM-23-1962.
In all cases the samples treated with the instant novel textile finish compositions showed much superior gas fading inhibition properties than a control sample treated with Gantrez AN-139 alone.
