  • Patent number: 4464271
    Abstract: Described are liqiud or solid fabric softener compositions of matter which effect a continuously high fragrance intensity release from the cloth or fabric treated with same, evenly and uniformly over an extended period of time and which can be adapted to yield differing aromas from a qualitative and quantitative standpoint in a controllable manner containing a mixture of (i) a non-confined fragrance composition; (ii) one or more fragrance oils which are physically entrapped in one or more types of solid particles and (iii) a suspending agent such as hydroxypropyl cellulose, silica, xanthan gum, ethyl cellulose or combinations of the previously mentioned four substances; the non-confined fragrance substance, the entrapped fragrance oil and the suspension agent being premixed prior to the subsequent creation of the liquid or solid fabric softener compositions of matter.

  • Patent number: 4353706
    Abstract: A process for sculpturing a pile fabric, e.g., nylon pile fabric, is provided which comprises selectively contacting the pile surface of said fabric with a fiber degrading composition, said composition comprising a fiber degrading agent in a concentration sufficient to reduce the tensile strength of the fibers of the pile in the selected areas so that said pile fibers may be removed by mechanical action; said fiber degrading agent being an aromatic sulfonic acid having a pK value of from about 0.

  • Patent number: 4304566
    Abstract: A process for the dyeing of textiles consisting of wool without anti-felt finish or wool having an anti-felt finish in the form of a coating of a polyimine resin or a polyacrylic resin, or textiles containing such wool, with reactive dyes according to the exhaust method, which comprises dyeing said textiles in aqueous dyeing baths containing at least one commercial reactive dyestuff the starting pH of which is in the weakly acidic to neutral range, by heating rapidly to the dyeing temperature of 110.degree. to 125.degree. C. immediately after addition of the dissolved dyestuff, and by dyeing at this temperature for 10 to 20 minutes, while omitting the addition of pH-regulating substances during the whole dyeing operation.

  • Patent number: 4304568
    Abstract: There is disclosed a method for minimizing ozone fading in dyed polyamides by treating the dyed polyamide with a substituted piperidine thiourea of the formula ##STR1## where R is a lower alkyl radical having 1-5 carbon atoms or phenyl. The treated dyed polyamides, preferably in fiber form, display minimize ozone fade without a reduction in light stability.

  • Patent number: 4277243
    Abstract: Improved levels of abrasion resistance, breaking strength are coupled with high levels of resilience, as measured by durable-press appearance rating and wrinkle recovery angles, by a process in which cotton or cotton-containing fabric is treated with polyfunctional N-methylol reagents, a Bronsted acidic catalyst or Bronsted acid-generating catalyst and selected phosphate salts. The fabric is impregnated with these and supplementary agents as desired and cured by conventional methods.

  • Patent number: 4263009
    Abstract: A method for improving the dyeing characteristics of textile materials containing polyolefin fibers is provided wherein the polyolefin fibers are coated with a coating composition consisting essentially of a film forming component containing at least one quaternary ammonium group. A preferred coating composition useful in the practice of the invention further includes a wetting agent and a minor effective amount of a fluorocarbon surfactant. Procedure for forming such coating compositions, application of same to polyolefin fibers, as well as dyeing of the coated polyolefin fibers is disclosed.In one embodiment the film forming component is the reaction product of a chemical substance containing at least one quaternary ammonium group and at least two amino groups having active hydrogen and a polyepoxide having at least two 1,2-epoxy groups per molecule. A method for producing such a film forming component and application of same to a textile material containing polyolefin fibers is also set forth.
