Definitions

• This invention relates to the treatment of textile materials and, more particularly, it concerns a process for softening textile materials in a repetitious but generally discontinuous cycle which involves soiling, laundering, rinsing, soiling, etc.
• softening agents to improve softness or hand of textile materials is well known. Aside from imparting softness, the treatment of textile materials with softening agents generally prevents the accumulation of static electric charges and makes the ironing of such materials easier. Only in the past two decades have softening agents become generally known by the housewife. Prior to this time, soap residues provided the same effect of improved hand or softness. With the advent of synthetic detergents which effectively remove fatty residues from the textile material, this benefit disappeared.
• Synthetic detergents are generally used in conjunction with builder materials such as alkali metal carbonates, silicates and/or phosphates. These so-called builder materials tend to react with the metal ions present in the wash liquor, precipitating out salts which deposit on the fibers of the textile material being laundered. Deposited mineral salts weaken the laundered fabrics, particularly at those points where the fabric is exposed to friction and creasing such as at the collar and cuffs. It has been found that treatment of these laundered textiles with softening agents not only soften the textiles, but also prolong their useful life.
• builder materials such as alkali metal carbonates, silicates and/or phosphates.
• softening agents Most of the softening agents presently used in home laundry situations are cationic surface active agents having at least one long alkyl radical usually containing from 16 to 18 carbon atoms. These softening compounds are not compatible with anionic synthetic detergents which are used in most heavy-duty detergents and, thus, are employed only during the rinse cycle. After a Wash cycle in which an anionic synthetic detergent is used, variable amounts of such detergent compound remain on the textile. This residual anionic detergent compound will react, during the rinse cycle, with any cationic soften- .ing additive causing precipitation and, thus, inactivation .of'the softener. Any interaction between the detergent compound and softener makes it difficult to achieve a uniform desirable degree of softening. Additionally, this interaction can result in a degree of deposition on the ,textile, material which causes waterproofing and reduced absorbency.
• cationic softening agents Another disagreeable feature of cationic softening agents is that those which have adsorbed to the softened textile can interact upon subsequent laundering with an Due to yellowing associated with the use of cationic softeners and the discoloration which inherently develops in cotton fabrics on aging, it is desirable to add a brightening agent to softener formulations. "These brighteners counteract the yellow hue of the fabric by giving off a blue-white fluorescence. Addition of brighteners to textile softener formulations intended for household use is common. Such brightener/softener formulations are greatly preferred by the average housewife.

• Non-expert panels of ten persons were employed. Each panel member was presented with four pairs of cloth swatches. The panelists were asked to handle each pair of swatches in turn and select the softer of the two cloths if a difference could be discerned. Two pairs of test swatches were comprised of the treated cloth and the control cloth presented in such a way that the treated cloth was handled first in one case and the control cloth in the other. The other two pairs of test swatches were comprised of control cloths exclusively and were designed to serve as a bench-mark for random selection between cloths of identical character. The order of presentation of pairs to the panelists was varied from person to person.
• Sets of fabrics comprised by four pairs of swatches were handled by no more than two persons each to avoid spurious results arising from pickup of skin oils, etc.

• EXAMPLE IV This example shows the ability of the amine oxide softener to be essentially completely removed by a single wash in-a typical heavy-duty anionic detergent formulation. This very desirable feature thus prevents the buildup "of the"softener on the fabric with consequent waterproofin'gand yellowing of the fabric due to breakdown of the quaternary ammonium compound.
• the fabrics were 'fsoft'e ried as before (Procedures A and C), then washed i'n a nautomatic washer with anionic detergent for'mulationone-o'r more times. The fabrics were present'e' the panel members both after application of the "'s'oftenerand after each subsequent wash to determine the softness impression.
• EXAMPLE v This example shows that the cloths softened with the amine oxide softeners having an alkyl radical of greater than 20 carbon atoms are such more absorbent than those which have been treated, with the quaternary ammonium salts which are ordinarily used.
• the cloths were exposed to 50 partsper million of the softener compounds in the usual way (Procedures A and C), washed in a standard anionic heavy-duty detergent formulation, then reexposed to 50 parts per million of softener in the rinse cycle. Washing and application of softener were repeated through a total of four cycles of softener application.

• EXAMPLE VII Sufficient docosyldimethylamine oxide to produce a level of 50 parts per million or 0.005% by weight of solution is introduced into the final the final rinse solution of a stnadard home automatic washing machine containing a load of mixed cotton fabrics from normal family usage. After completion of the rinse cycle, that is, exposure for about 5 minutes and then spin drying, the load is dried in an automatic dryer. Upon panel grading essentially like that of Procedure C, the fabrics are judged to be much softer and more desirable than fabrics which have not been treated with the amine oxide.
• Example VIII When the conditions of Example VII are repeated using a mixed family load containing fine fabrics such as nylon and polyester and using a 50-50 mixture of eicosyldimethylamine oxide and docosyldimethylamine oxide it is seen that the fine fabrics are rendered largely antistatic and are much more desirable when worn than are the control fine fabrics which are not given a treatment with the amine oxide compound.
• EXAMPLE IX This example shows the usefulness of a 50-50 mixture of eicosyldimethylamine oxide and docosyldimethylamine oxide when used in a padding-on process.
