  • Patent number: 4217104
    Abstract: Fur skin production process comprising treating skins at a stage of processing when they contain 30-80 weight water by immersion in or contact with an organic liquid carrier medium which is water immiscible and not very volatile and contains tanning or further process step chemicals. After tanning or further process steps most of the carrier is removed by centrifuging, squeezing or other physical force process carried out substantially at ambient temperature with little or no heat input. Such processing affords advantages of reduced health hazards and apparatus problems (by avoiding solvent use), reduction of fat liquor and/or kicking oil requirements, reduction of matting on fine wolled skins and avoidance of the need to reverse the skins repeatedly (of skins worked in the round).
