Definitions

  • This disclosure relates to the field of treating fibrous articles using foams of amphiphilic proteins to improve the fibrous article treating process.
  • textile effect additives are used to impart desirable properties or effects to a treated article.
  • Fibrous articles such as textiles are usually treated by immersion of the fibrous article in a water bath containing the textile additives. The article becomes saturated with water in the process. Excess water must be removed from the fibrous article, and the fibrous article must then be dried to allow its further processing. The drying step can be time-consuming and energy inefficient.
  • the amount of water retained by the fibrous article also known as
  • wet pick up is normally about 50 to 70 percent water based on the weight of the fibrous article. This large amount of water requires a tremendous amount of energy in the form of heat to dry the fibrous article. It has been estimated that the amount of energy required to remove the water and dry the fibrous article is many times greater than the amount of energy that is needed for curing the fibrous article to prepare it for additional finishes.
  • foams have been used to treat textiles and obtain uniform application of treatment compositions on porous articles while also reducing the amount of water used in the process.
  • compositions disclosed herein are intended to address these issues in the treatment of fibrous articles.
  • this disclosure describes a foam composition
  • a foam composition comprising: (i) at least one amphiphilic protein; and (ii) at least one textile effect additive.
  • this disclosure describes a process for treating a fibrous article that is useful for producing a fibrous surface that is oil and water repellant, the process comprising the steps of:
  • a) producing a foam comprising: (i) at least one amphiphilic protein; and (ii) at least one textile effect additive;
  • the foam is produced by a process comprising the steps: i) providing a first aqueous solution comprising at least one textile effect additive; ii) providing a second aqueous solution comprising at least one amphiphilic protein; iii) contacting the first aqueous solution with the second aqueous solution to produce an aqueous mixture; iv) producing a foam phase and a liquid phase from the aqueous mixture; and v) allowing the foam phase to separate from the liquid phase to produce the foam comprising the additives of step (i) and the amphiphilic proteins of step (ii); wherein the fibrous surface is treated in the absence of any wetting or thickening agents, and wherein the fibrous surface has a water and oil repellency of greater than 1 after it is treated.
