Abstract
The invention discloses a double waterproof chromium-free tanned sheep fur and its making method. The preparation method is characterized in that a fur skin water proofing and fur fleece proofing combination process is adopted, a waterproof fatting agent is added in the fatting process, and the surface water proofing treatment is carried out after fixing to make the fur skin reach a depth water proofing effect; and then the water proofing treatment of the fur fleece is carried out in the dry finishing phase. According to the invention, the industrial-production double waterproof chromium-free tanned sheep fur has a shrinkage temperature reaching above 85DEG C, can be permanently stored without detanning and does not contain chromium; the static water absorbing capacity of the fur skin is about 20%, and the deflection frequency is 4000-8000 or more; the zero water absorbing property, the zero water penetration property and the zero surface wetting performance of the fur fleece make water roll on the sheep fur fleece in sphere shape and the fur fleecy not wet, so the sheep fur has an obviously waterproof property; and the tensile strength is not less than 10N/mm<2>, the fracture elongation rate is not less than 50%, and the formaldehyde content is not more than 360mg/kg.
