Definitions
- urea and glyoxal are reacted under alkaline conditions to produce 4,5-dihydroxy-2-imidazolidinone, which is then reacted with formaldehyde under neutral or alkaline conditions (see U.S. Pat. Nos. 2,731,472 and 2,764,573).
- urea and formaldehyde are reacted under alkaline conditions to produce dimethylol urea which is then reacted with glyoxal under alkaline conditions to form the imidazolidinone. (see U.S.
- the invention is a process for preparing a textile finish composition of an aqueous solution of a watersoluble urea-formaldehyde-glyoxal condensation product and the composition and the use of the composition on textiles to produce a curable finish having a low level of emission of formaldehyde which when cured imparts desirable durable press properties to the textile materials thus treated.
- the invention provides a process for preparing aqueous solutions of a water-soluble urea-formaldehydeglyoxal condensation product containing 1,3- dimethylol-4,5-dihydroxy-2-imidazolidinone, sometimes referred to as dimethylol monourein or dimethylol dihydroxyethyleneurea, that are characterized by low levels of formaldehyde released by fabrics treated therewith and which are effective as durable press agents for cellulosic textile materials.
- the invention provides a three-step process for preparing the water-soluble urea-formaldehyde-glyoxal condensation product which comprises reacting in a first step relative amounts of 1 mole of urea and about 1 mole of glyoxal with less than 2 moles of formaldehyde (about 1.4 to about 1.9 moles) in an aqueous medium at a pH between 6.2 and 6.7 at a temperature between 40 and 90C. for a period of about 0.5 to 10 hours, reducing the pH of the reaction mixture in the second step by the addition of an acid to obtain a pH between 2.0 and 3.0 and maintaining a temperature between 40 and 90C.
- the period for maintaining the temperature at a pH of 2 to 3 may be increased to more than 3 hours, but to no particular advantage.
- the free formaldehyde content of the product initially ranges from about 0.2% to about 1.0% on the weight of the solution but after several days it decreases to about 0.2% to 0.5%.
- the reaction is preferably carried out in water and the formaldehyde used may be the commercial 37% or 44% formaldehyde solutions of paraformaldehyde.
- the second step of the process the pH is preferably adjusted by the addition of an acidic material such as citric acid to a pH value between 2.4 and 3.0 and the temperature is raised to 60C. and held between 55 and 65C. for a period of at least 1.5 to 3.0 hours.
- the solution is then cooled to about 25C. and in the third step of the process the pH of the final product is adjusted to a value between 5.0 and 7.0.
- Examples of the acidic material useful for adjustment of the pH in the second step of the process to a pH of about 2 to 3 include: organic carboxylic acids such as citric, tartaric, gluconic, oxalic, malic, and the like; inorganic acids may also be used such as hydrochloric,
- a typical final product of this invention may be characterized as a composition containing 1,3-dimethylol- 4,5-dihydroxy-2-imidazolidinone having between 1.6 and 1.9 moles of combined formaldehyde and from 0.02 to about 0.05 moles of free formaldehyde per mole of urea used plus water and about 5% of dissolved salts, depending on the acid used.
- the typical product will be almost a water white liquid having a pH between 6.0 and 7.0.
- the free formaldehyde should be less than 0.5% and preferably less than 0.2% on the weight of the product.
- the textile compositions obtained by the process of this invention are stable almost colorless solutions and are readily dilutable with water in all proportions.
- the products of this invention are useful in imparting durable press properties to cellulosic textile materials and as such may be applied to such materials by any of the conventional procedures used in the textile industry. Thus, they may be applied by padding, dipping, spraying, immersing and the like.
- the products of this invention are superior to the durable press products of the prior art processes from the standpoint of the low levels of formaldehyde released from cellulosic materials prior to the conventional curing procedures.
- the low emission of formaldehyde after the drying operation and prior to the final curing step is an important improvement in post-cure durable press processing.
- the product of this invention may be employed with other textile agents and auxiliaries such as surface active agents, softeners, brighteners, odorants and other crease-proofing agents.
- 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 reaction mixture is cooled to about 40C. and 8.9 parts of anhydrous citric acid is added to provide a pH of 2.7. The temperature is then raised to 60C. i 2C. The reaction mixture is then stirred at pH 2.7 for 3 hours at 60C. and the pH is then adjusted to 6.26.6 by the addition of 50% aqueous sodium hydroxide. The reaction mixture is then diluted with water to give a total weight of 270 parts.
- the product is an aqueous solution of 1,3- dimethylol-4,5-dihydroxy-2-imidazolidinone containing about 45% solids and 0.7% of unreacted formaldehyde. After storage at room temperature for several days the solution contains 0.3% of unreacted formaldehyde.
- the pad baths were applied by standard padding pro- Table [V cedure to 65/35 polyester-cotton shirting fabric obtaining a 70% wet pick-up.
- Apphca water-soluble urea-formaldehyde-glyoxal condensation tions were then made by conventional procedures to product comprising 65/35 Polyester cotton Shifting and the durable Press reacting in an aqueous medium about 1.0 mole of result was noted using a standard AATCC test as well urea, about 1.0 mole of glyoxal and less than 2.0 as the yellowing to scorch test, AATCC test.
