• My present invention relates to a process for improving the felting property of animal hair. More particularly, it relates to a process of treating animal hair before the felting process with a solution of a fluorine compound.
• the natural animal hair used for manufacturing hair felts does not have sufficient felting property and must therefore be 'sub- 1 jected to a preliminary treatment to improve this property.
• the mordant generally used .for this purpose is nitrate of mercury. It has been used in spite of its well known poisonous action (see for instance Syrup,
• the skins thus treated have as good a felting property as when treated with nitrate of mercury and yield according to the usual processes solid felt hats.
• Example 2 100 parts of rabbit or hare hair are treated at 30? for 12 hours with 1000 parts of a solution containing 2-4: parts of potassium bifiuoride. Then the goods are centrifuged and dried at a moderate temperature.
• the hair thus prepared felts well does not show the yellowish shade of hair treated with nitrate of mercury and is well suited for manufacturing solid felt hats.
• a process which comprises treating animal hair before the felting process with a solution of a fluoride.
• the hair may be subjected to my process either on the skin or already cut or also in the first stage of felting.
