Definitions

  • This invention relates to textiles and textileforming materials which are made resistant to shrinkage upon wetting or washing by the incorporation of resinous materials therein. While the invention is directed particularly to improved textile treating processes resulting in shrinkage resistance and in many cases improved tensile strength in the textiles and textile-forming materials it includes also the finished textiles themselves when prepared by the process of the invention.
  • textile materials which term includes spun, woven, knitted and felted textiles as well as the raw materials such as loose wool, staple cotton fibers, etc., from which they are prepared, can be rendered resistant to felting and shrinking by impregnation with an aqueous dispersion of substantially unpolymerized alkylated melamine-formaldehyde condensation products, which are also known as alkylated methylol melamines.
  • substantially unpolymerized alkylated melamine-formaldehyde condensation products which are also known as alkylated methylol melamines.
  • Our invention in its broader aspects therefore includes textile treating procfises of the class described in which any suitable aterial capable of combining with formaldehyde 5 i incorporated into the textiles along with alkylated methylol melamines, but thiourea, urea and mixtures thereof constitute the preferred materials.
  • the quantities of urea, thiourea and other formaldehyde-binding materials effective to accomplish these results are such that no serious reduction in shrinkage control is encountered, and therefore the process of our invention combines a high degree of shrinkage control with satisfactory strength in the treated textile material.
  • alkylated methylol melamines are prepared by a similar process, substituting ethanol, propanol, butanol and the like for the methyl alcohol.
  • These resinous condensation products are preferably used in quantities of about 2-15%, based on the dry weight of the textile materials, although higher quantities up to 25% may be employed if desired.
  • the quantity of urea, thiourea or other aldehyde-binding material will vary with the nature of the textile materials. Thus, for example, rayon and cotton require more than wool.
  • the amount may also vary with the type and quantity of alkylated methylol melamines employed. We have found that as little as 1% of urea or thiourea is effective to prevent substantial loss of strength in some cases, but the preferred quantities range from about 2 to about 10%.
  • Ammonia is preferably used in considerably smaller quantities because of its lower molecular weight, while larger quantities of melamines, guanidines, phenols and thelike are employed for the same reason.
  • the formaldehyde-binding materials, and parassess-r tlcularly urea and thiourea are preferably incorporated into the aqueous solution of alkylsted,
  • EXAMPLE 1 All wool flannel cloth was treated for shrinkage control by impregnation with aqueous solutions of methylated methylol melamine containing 0.4% of diammonium hydrogen phosphate, based on the weight of the resin, followed by drying and curing by heating 9 minutes at 290 F.
  • Varying quantities of urea and thiourea. were dissolved in the aqueous resin solution prior to impregnation of the cloth therewith.
  • the finished cloth was tested for tensile strength and for shrinkage control by standard methods.
  • Tensile strength was measured on a Scott Tester, I. P. No. 3, with grab hooks set 3 inches apart.
  • Shrinkage was determined by successive 10 minute launderings in a soap solution giving good running suds at 100 F., rinsing in warm water and drying fiat in an oven without tension after each wash.
  • the dried samples were conditioned over nightbefore measuring. A final one-hour laundering followed five such 10 minute treatments.
  • the stiffening composition was an equeous emulsion containing by weight of a solution in butanol of a soya fatty acid modified phthalic glyceride resin and 13.5% of a 50% butanol solution of a butylated urea-formaldehyde resin.
  • the resin solids applied from this emulsion were therefore about 2%, based on the dry weight of the nylon.
  • EXAMPLE3 Mercerized cotton twill was finished with 10% of methylated methylol melamine. alone and containing 5% of urea, based on the dry weight of the cotton. The untreated and treated pieces were tested for tensile strength and for shrinkage after three successive l-hour launderings, using the procedure described in Example 1. The results are shown in the following table.
