Definitions
- This invention relates to a nondiscoloring, durable press finish for dyed or undyed, cellulosic textile materials, More particularly, it relates to a process of applying an aqueous finish containing l,3-dimethylol-4,5- dihydroxy-2-imida2olidinone of Formula I, a Zinc nitrate catalyst and a sequestering agent to cellulosic materials, and to the treated cellulosic materials.
- l,3-Dimethylol-4,5-dihydroxy-2-imidazolidinone is a very valuable finishing agent for textile materials. It has a wide and extensive use on cellulosic materials and blends of cellulosic materials with other fibers such as polyamides (nylon) and polyesters (Dacron). It is generally used together with sodium acetate. Although it can be used as a conventional wash-and-wear finish, its greatest use is in the durable press field, especially in the postcure process as described in U.S. Pat. No. 2,974,432. Zinc nitrate is the preferred curing catalyst. The finish has not, however, been entirely satisfactory since it is not compatible with other operations performed on the textile materials. For example, it has been found that it causes scorching on white goods during the pressing operation and yellowing during the postcuring operation.
- Zinc nitrate is the preferred catalyst for use in curing l,3-dimethylol-4,5-dihydroxy-Z-imidazolidinone.
- Other zinc salts such as zinc chloride and zinc sulfate, do not produce the desired wash-and-wear" properties.
- Other curing catalysts such as magnesium chloride, are also not as satisfactory as zinc nitrate and are not used.
- a further object is to provide a method and finish for undyed cellulosic textile materials incorporating 1,3- dimethylol-4,5-dihydroxy-Z-imidazolidinone and zinc nitrate, for obtaining wrinkle resistance or permanent creases on said textiles, which does not cause yellowing on curing or scorching on hot pressing or ironing after washing.
- Another object is to provide a method and finish for cellulosic textile materials incorporating 1,3- dimethylol-4,5-dihydroxy-2-imidazolidinone and zinc nitrate, for obtaining wrinkle resistance or permanent creases on said textiles, which does not discolor, resin sensitive" dyes on said textile materialsv
- a further object is to obtain an undyed textile material which is wrinkle resistant or permanently pressed and which does not yellow on curing or scroch on pressing.
- Another object is to obtain a dyed textile material which is wrinkle resistant or permanently pressed and wherein the shade is not discolored.

This invention relates to a nondiscoloring, durable press finish for dyed or undyed, cellulosic textile materials, More particularly, it relates to a process of applying an aqueous finish containing l,3-dimethylol-4,5- dihydroxy-2-imida2olidinone of Formula I, a Zinc nitrate catalyst and a sequestering agent to cellulosic materials, and to the treated cellulosic materials.
l,3-Dimethylol-4,5-dihydroxy-2-imidazolidinone is a very valuable finishing agent for textile materials. It has a wide and extensive use on cellulosic materials and blends of cellulosic materials with other fibers such as polyamides (nylon) and polyesters (Dacron). It is generally used together with sodium acetate. Although it can be used as a conventional wash-and-wear finish, its greatest use is in the durable press field, especially in the postcure process as described in U.S. Pat. No. 2,974,432. Zinc nitrate is the preferred curing catalyst. The finish has not, however, been entirely satisfactory since it is not compatible with other operations performed on the textile materials. For example, it has been found that it causes scorching on white goods during the pressing operation and yellowing during the postcuring operation.
Moreover, it has not been found to be satisfactory for use with certain resin sensitive dyes such as a group of blue vat dyes based on indanthrone (Formula ll) and its chlorinated derivatives thereof which have considerable commercial value.
When a cellulosic fabric dyed with one of the indanthrone dyes is treated with a textile finish containing l,3-dimethylol-4,5-dihydroxy-Z-imidazolidinone, followed by a curing operation in the presence of zinc nitrate as the curing catalyst, the shade of the fabric is severly altered, becoming duller and much greener. The color change is so drastic that cloth dyed with one of the indanthrone dyes cannot, therefore, be treated with a wrinkle resistant finish containing 1,3- dimethylol-4,5-dihydroxy-Z-imidazolidinone and Zinc nitrate.
Zinc nitrate is the preferred catalyst for use in curing l,3-dimethylol-4,5-dihydroxy-Z-imidazolidinone. Other zinc salts, such as zinc chloride and zinc sulfate, do not produce the desired wash-and-wear" properties. Other curing catalysts, such as magnesium chloride, are also not as satisfactory as zinc nitrate and are not used.
Therefore, the need exists for a method of applying and heat curing a textile finish containing [3 dimethylol-4,5-dihydroxy-2-imidazolidinone with the Zinc nitrate catalyst to give a wrinkle resistant or permanent crease finish which is compatible with other.
operations, particularly with white cellulosic materials which will prevent or reduce l) yellowing on curing. and (2) scorching on hot pressing, and with cellulosic materials dyed with resin-se,nsitive" dyes.
It is therefore an object of this invention to provide a finish and a method for rendering cellulosic textile materials wrinkle resistant or providing a permanent crease, said finish being compatible with other opera' tions on said textile material.
A further object is to provide a method and finish for undyed cellulosic textile materials incorporating 1,3- dimethylol-4,5-dihydroxy-Z-imidazolidinone and zinc nitrate, for obtaining wrinkle resistance or permanent creases on said textiles, which does not cause yellowing on curing or scorching on hot pressing or ironing after washing.
Another object is to provide a method and finish for cellulosic textile materials incorporating 1,3- dimethylol-4,5-dihydroxy-2-imidazolidinone and zinc nitrate, for obtaining wrinkle resistance or permanent creases on said textiles, which does not discolor, resin sensitive" dyes on said textile materialsv A further object is to obtain an undyed textile material which is wrinkle resistant or permanently pressed and which does not yellow on curing or scroch on pressing.
Another object is to obtain a dyed textile material which is wrinkle resistant or permanently pressed and wherein the shade is not discolored.
These and other objects of the invention will become apparent as the description thereof proceeds.
A method has now been discovered for applying 1,3- dimethylol-4,5-dihydroxy-2-imidazolidinone to undyed cellulosic materials which will prevent or reduce yellowing on curing and scorching on hot pressing and to dyed textile materials to prevent discoloration of the dye.
In the process of the invention an aqueous solution of l,3-dimethylol-4,5-dihydroxy-2-imidazolidinone, a sequestering agent, and zinc nitrate is applied to the cellulosic textile material. The textile material is then dried and the finish is cured at an elevated temperature. in a postcure process, the dried fabric is made into a garment or other article which is then pressed and cured.
Cellulosic textile material has the usual meaning and includes blends with other fibers such as polyamides (nylon) and polyesters (Dacron), including woven, knitted, felted, or other textile goods, for example.
Suitable sequestering agents for use in this invention are described in Volume 12, page 164, of Enyclopedia of Chemical Technology, first edition, and in Organic Sequestering Agents by Chaberek 1959).
The two principal classes of sequestering agents which are suitable are the aminopolycarboxylic acids, such as ethylenediaminetetraacetic acid, nitrilotriacetic acid, di(hydroxyethyl)glycine, (hydroxyethyl)ethylenediaminetriacetic acid and diethylenetriaminepentaacetic acid, and the hydroxycarboxylic acids, such as gluconic acid, citric acid, malic acid and tartaric acid. These are used as partially neutralized alkali metal salts.
The resin sensitive dyes include certain dyes of several classes, such as direct dyes, sulfur dyes, reactive dyes, disperse dyes, vat dyes, and particularly indanthrone vat dyes.
The indanthrone dyes include indanthrone (C.l. Vat Blue 4, C. I. No. 69800), dichloroindanthrone (C.l. Vat Blue 6, C.l. No. 69825), monochloroindanthrone (C. l. Vat Blue 14, C. l. No.-698l), mixture of mono-, diand trichloroindanthrone's(C. l. Vat Blue 10, C. 1. No. 69830), etc.
The sequestering agent can be put on the cellulosicmaterials simultaneously with, prior to or subsequent to the application of the 1,3-dimethylol-4,5-dihydroxy-Z-imidazolidinone and zinc nitrate. It is preferred to apply the imidazolidinone, zinc nitrate and sequestering agent from the same aqueous solution. However, the sequestering agent can be applied from an aqueous solution before or after the application of the imidazolidinone and zinc nitrate.
The aqueous solution of l,3-dimethylol-4,5-dihydroxy-2-imidazolidinone, sequestering agent, and zinc nitrate is applied to the textile material by any of the normal methods of application, such as by padding, spraying, dipping and the like.
The amount of l,3-dimethylol-4,5-dihydroxy-2- imidazolidinone applied to the textile materials should be between 1.0 and 25.0 percent, preferably between 3.0 and 8.0 percent, based on the weight of the textile material.
The amount of sequestering agent used should be between 0.05 and 3.0 percent, preferably between 0.15 and 1.0 percent based on the weight of the solution. This corresponds to between about 0.025 and 3.0 percent, preferably between about 0.075 and 1.0 percent. based on the weight of the fabric.
The amount of zinc nitrate should be between 5.5 and 16.5 percent, preferably between 9.5 and 12.5 percent, based on the weight of the imidazolidinone.
The treated fabric may be dried and cured by conventional wash-and-wear procedures. Also, the well known postcuring procedure of US. Pat. No. 2,974,432 can be used. which consists of drying the treated fabric; cutting, sewing and pressing the garment; and curing the finish on the garment at an elevated temperature.
The treated textile material is normally dried before the pressing and curing operations are performed. A drying temperature between 175 and 250F.. preferably between 200 and 22-5F., is used. The pressing operation can be done by any of the methods well known in the trade, such as by the use of a hot head press. The pressing operation is carried out at'a temperature of 300 to 420F. In the curing operation, the pressed fabric is heated at an elevated temperature under conditions normally used by the trade which is at a temperature between 300 and 420F., preferably between 320 and 380F., for a period sufficient to react the imidazolidinone with the cellulosic fabric. Heating periods between 5 and 20 minutes are normal.
The textile finish of this invention is compatible with many fluorescent brightening agents normally used on cellulosic materials, particularly the stilbene class of brightening agents.
Undyed cellulosic fabrics treated by the process of this invention have good resistance to scorching and discoloration when the fabrics are pressed and cured at elevated temperatures.
In one preferred embodiment of the invention with dyed fabrics, a cotton fabric dyed with an indanthrone vat dye is padded with an aqueous solution containing about 9 percent of l,3-dimethylol-4,5-dihydroxyimidazolidinone, about 1 percent of zinc nitrate and about 0.35 percent of ethylenediaminetetraacetic acid, tetrasodium salt. The treated fabric, containing about 6 percent of the imidazolidinone is dried at 225F. The dried fabric is then cut and sewed into garments which are pressed at about 310F. The pressed garments are then heated in an oven at about 340F. until the imidazolidinone is cured on the garment. The thus treated garment is durably pressed" where creases are desired and is wrinkle resistant in those areas where wrinkles and creases are not desired. During the pressing and drying operation the shade of the dyed fabric is essentially unchanged.
It has been discovered thatthe sodium acetate normally used in the finish containing 1,3-dimethylol-4,5- dihydroxy-2-imidazolidinone to decrease the initial losses in tensile strength, tear strength and'abrasion resistance is not required when the sequestering agent is used. Additionally, the sequestering agent appears to give more stable pad baths than sodium acetate. It has been found that the sequestering agent used in the invention does not cause precipitation of thefluorescent brightening agents in finishing baths.
The nonionic surface active agent used in the examples is the condensation product of nonylphenol with an average of 9.5 moles of ethylene oxide. Other suitable nonionic surfactants can also be used, such as other alkyl aryl polyethylene glycol ethers and ethylene oxide adducts of straight chain alcohols.
The fluorescent brightening agent used on undyed goods is C. l. Fluorescent Brightening Agent 25, a compatible brightening agent. It is a commercial product belonging to the sulfonated diaminostilbene class of brightening agents and was employed as an aqueous solution. In addition to this particular brightening agent, any other suitable ones can be used such as other members of the sulfonated diaminostilbene class, providing they are compatible with the other components of the finish.
For commercial application, it is often desirable to prepare a resin mix containing the imidazolidinone, sequestering agent and water to which the zinc nitrate, preferably as an aqueous solution, is added to form the pad baths prior to use. Suitable resin mixes contain between 1 and 90 percent imidazolidinone, a preferred range beingbetween 30 and 50 percent; between 0.1 and percent sequestering agent, a preferred range being between 1.0 and 4.0 percent.
Pad bath preparation is greatly simplified by controlling the extent of neutralization of the sequestering agent in such a manner that when the zinc nitrate catalyst has been added, a pad bath having the sequestering agent in the desired degree of partial neutralization is produced without the need for further addition of acid or base.
The following specific examples are set forth to illustratethe preset invention and are notintended to be limitative thereof. Parts and percentages. used herein are by weight unless otherwise indicated.
EXAMPLE 1 Eightaqueous pad baths were prepared, each bath containing 11.2 percent of 1,3-dimethylol-4,5-dihydroxy-2-im'idaz'olidinone, 1.25 percent of zinc nitrate, 0.25 percent of a nonionic surface active agent. 0.5
percent of C. I. Fluorescent Brightening Agent 25, and
sodium acetate or a sequestering agent as shown in Table I. The pH of the pad baths was adjusted to 4.7 by addition of sodium hydroxide or hydrochloric acid as required.
(hydroxyethyl )ethylenediaminetriacetic acid, trisodium salt The pad baths were applied by standard padding procedure to a 65/35 polyester/cotton fabric obtaining a .70 percent wet pickup. The fabrics, containing 7.9 percent on the weight of the fabric of l,3-dimethylol-4,5-
dihydroxy-Z-imidazolidinone, were dried for 1 minute at 225F., steamed for 5 seconds, pressed for 5 seconds at 350F., and heated in an oven at 320F. for 8 minutes. I
The fabrics were examined for discoloration by comparing the color of the treated fabrics with that of the untreated fabric.
The fabrics were laundered 5 times in a homestyle washing machine using water at 130 140F. and a detergent followed by a rinse water treatment at about I10-120F. and tumble drying after each washing. The
