  • Patent number: 4472165
    Abstract: A method for the removal of free formaldehyde from textile fabrics which have been treated with formaldehyde derived resins to make the fabrics crease-resistant is disclosed. The process comprises forming a composition composed of a foaming agent, ethylene urea and an appropriate diluent and then foaming this composition to form a stable foam. The foam is then applied to the resin treated fabric in a layer, the foam is collapsed on the fabric to force it through the fabric and then the fabric is subjected to drying and curing conditions. The process is advantageous in that it utilizes relatively small volumes of liquids and thus is energy efficient and environmentally favorable.

  • Patent number: 4447241
    Abstract: The level of released formaldehyde in a durable press treated fabric is significantly reduced or eliminated altogether by an oxidative aftertreatment process in which the fabric, after treatment with a formaldehyde-based durable press finishing agent and curing to impart durable press properties, is contacted with an oxidizing agent to destroy formaldehyde-releasing moieties present in the fabric. Preferably, the treatment of the durable press fabric with the oxidizing agent is carried out by impregnating the fabric with a solution containing the oxidizing agent and then providing the fabric a residence time in contact with the oxidizing agent to allow for reaction of the oxidizing agent with the formaldehyde-releasing moieties.

    Abstract: A process is described for obtaining finishing effects on textile material consisting, at least partially, of cellulose fibers, without seriously reducing the tensile strength, tearing strength or wearing strength of the fibers. A finishing agent, capable of cross-linking with the hydroxy groups of the cellulose fibers, in a solution or emulsion containing a mixture of water and at least one organic solvent, such as low aliphatic ketones, aliphatic chlorinated hydrocarbons or low aliphatic esters, is applied to the textile material. The stability of the mixture is controlled by a salting-in or salting-out effect so as to induce a phase separation between aqueous and solvent phase, this effect being induced by the use of neutral salts, acid salts, potentially acid salts, organic acids, synthetic resins or reactants. The finishing agent is concentrated in the aqueous phase in the interior of the individual fibers while the surface zones retain the good surface properties of the starting material.

  • Patent number: 3975154
    Abstract: This invention relates to the preparation and use of durable press fabrics with strong acid grafts. The preparation is accomplished by the incorporation of a reactive hydroxyalkyl sulfonic or phosphinic acid in a crosslinking finishing system. As a consequence of this, durable press fabrics are produced with sulfonic or phosphinic acid grafts. Because of these strong acid grafts, these fabrics show improved moisture regain properties, can be dyed with basic dyes, can be whitened with basic optical brighteners and have ion exchange properties for metallic cations.

  • Patent number: 3970424
    Abstract: Improvement in strength and elimination of coloration are achieved in fabrics finished for durable press properties by treatment with an N-methylol amide crosslinking agent and aluminum sulfate catalyst when sodium dihydrogen phosphate is included in the finishing formulation. These effects are achieved when the weight ratio of sodium dihydrogen phosphate to aluminum sulfate is 2.05.

  • Patent number: 3954405
    Abstract: Textiles are impregnated with a solution of dimethylol dihydroxyethylene urea or a partially or wholly methylated derivative thereof, phosphoric acid as catalyst and sodium metaborate as buffering agent. Impregnated textile is heated to cure the solution and impart crease-resistance to said textile.

  • Patent number: 3948600
    Abstract: In mild cure finishing, strong catalysts are required because of the modest curing conditions employed in the process. Suitable catalysts for mild cure finishing include strong inorganic acids, strong organic acids, active inorganic complexes, salt/acid combinations, and salts that are strong Lewis acids (i.e, certain metal salts). Ammonium salts of inorganic acids, although often used in other types of treatments for producing wrinkle resistant textiles, are not satisfactory catalysts for mild cure finishing. Unexpectedly and surprisingly, it has been discovered that ammonium salts of certain, but not all, sulfonic acids can serve as effective catalysts for mild cure finishing of cellulose-containing fabrics to produce wrinkle resistance and durable press properties. Among ammonium sulfonates which provide the catalysis needed for mild cure finishing are ammonium methanesulfonate, ammonium carboxymethanesulfonate (NH.sub.4 O.sub.3 SCH.sub.2 COOH), ammonium benzenesulfonate, and ammonium p-toluenesulfonate.

  • Patent number: 3933426
    Abstract: This invention relates to a process for making textiles containing cellulose crease-resistant.The process of the invention involves contacting the textile with an aqueous treatment bath to which alkali chlorides or bromides of sodium and potassium have been added and which contains 1,3-dimethylol-4,5-dihydroxyethylene urea, the hydroxyl and methylol groups of which can optionally be partially or completely etherified with low, monohydric aliphatic alcohols with 1 to 3 carbon atoms and potential acid catalysts. It is possible for the treatment bath to contain in addition other precondensates normally used in the treatment of textiles provided at least 40% by weight based on the weight of the sum of the N-methylol derivatives calculated as anhydrous substances is the optionally etherified 1,3-dimethylol-4,5-dihydroxyethylene urea.

  • Patent number: 3933274
    Abstract: A product adapted for the treatment of cellulosic fabric comprises a container having at least two compartments for holding two or more fluent substances separate from one another but adapted for dispensing the substances simultaneously, and having in one compartment a resin precondensate and in another compartment a latent acid catalyst. The product is used to make aqueous solutions of both resin precondensates and latent acid catalysts for fabric treatment, whilst keeping the ingredients separate until required for use.
