  • Patent number: 4527992
    Abstract: This invention relates to a process for producing waterproof leathers and skins by tanning, retanning, dyeing, stuffing, and fixing which is characterized in that, after tanning and, optionally, dyeing, stuffing agents (A) in the form of oxidized or oxidized and partly sulfonated long-chain hydrocarbons of waxes and impregnating agents (B) in the form of copolymers or from 60 to 95 mol percent of (meth) acrylic acid and from 5 to 40 mol percent of an ester, amide or nitrile of (meth) acrylic acid having a molecular weight of from 800 to 10,000 in salt form are successively used in the same bath, followed by acidification, fixing and finishing. The co-use of the impregnating agents (B) with the particular stuffing agents (A) results in much greater degree of resistance to water penetration than that obtained by the use of the stuffing agent (A), alone.

  • Patent number: 4514185
    Abstract: Fabric, particularly soiled fabrics containing calcium carbonate crystal growth poisons, may be washed in hard water to which has been added a detergent active material and an alkali metal carbonate if a secondary detergency builder is added after a defined critical state of the system is reached. The secondary builder may be a precipitating, sequestering or ion exchange builder, and is added in such an amount which would be insufficient, in the absence of the carbonate, to reduce the free calcium ion concentration to less than 10.sup.-5 molar. The delayed addition can be achieved by separate dosing, coating the secondary builder, dosing the composition in the form of a two-compartment sachet or forming the secondary builder material in situ. The composition may include a material, such as calcite, to promote the occurrance of the critical state.

  • Patent number: 4502859
    Abstract: An animal hide tanning composition is comprised by weight of minor proportions of borax and alum blended together with an emulsifying agent in a carrier containing water and water-emulsive oils. In the method of preparing the composition, the sequence of blending is extremely important to achieve desired consistency and assure complete dissolution of the active ingredients while retaining the preservative qualities thereof. If a bactericide and parasiticide are to be included, they may be added during the initial blending step. The emulsifying agent acts as a stabilizer to maintain the composition in a readily usable physical state while the addition of a bactericide and parasiticide prevent decay of the tanned hide otherwise resulting from organisms which may be present in the hide.

  • Patent number: 4501591
    Abstract: The invention relates to an improvement in certain processes for continuously dyeing polyamide carpets whereby stain resistance is imparted to the carpets during the dyeing process. The improvement involves adding an alkali metal silicate (e.g. sodium meta silicate) and a sulfonated phenol-formaldehyde condensation product to the dye liquor used in the dyeing process. If either the silicate or condensation product is omitted from the liquor, the improvement is not achieved. The improvement provides a convenient and economical means for providing stain resistant polyamide carpets.
