摘要： A method for treating leather with a low fogging, substantive, retan fatliquor containing a dispersion of a selected amphiphilic copolymer , substantially free from organic solvents, formed from a predominant amount of at least one hydrophobic monomer and a minor amount of at least one copolymerizable hydrophilic monomer. The method produces leather having desirable strength and softness qualities and particularly reduced fogging characteristics. The treated leather is particularly suitable for use in vehicle upholstery.

摘要： In the tanning of heavy leather, leather stock is subjected to a multiple-stage tanning process under carefully controlled pH conditions to improve its characteristics such as fullness and firmness. Leather stock at a pH of from 4.5 to 5.5 is treated with polymer containing units of acrylic and/or methacrylic acid and optionally, at least one of acrylic ester, methacrylic ester and partially sulfated drying oil and then, at a pH of from 1 to 3.3 treated with a mineral tanning agent. Preferably the mineral tanning agent comprises a zirconium tanning compound having a basicity on the Schorlemmer scale of from 0 to 45%, a buffered aluminium sulfate tanning compound or a mixture thereof. The leather is subsequently neutralised, washed and dried and may be used for shoe soles, belts, . straps, bags, cases, saddles, bridles and harnesses.
