  Verfahren, um Seide verfilzbar zu machen. 



   Das Verfahren ist bedingt durch den    EiwriLkharakter   der   Seide und deren Quellbarkeit   und teilweisen Auflösungsfähigkeit in kalter Ameisensäure, ohne dass dadurch weitergehende   Ausspaltungen   des   Fibroinmoleküls   stattfinden. 



   Beispiel I :   Man entbastet kleinfaserige Seide (Seidenabfall) nach bekannten Methoden, behandelt   mit kaltem Wasser, bis die Faser gut ausgewaschen, schlämmt mit Ameisensäure an, bis ein   gleichmässiger Faserhrei entsteht,   gibt diesen auf geeignete Siebvorrichtungen, welche das Ablaufen der Ameisensäure gestatten und bringt hierauf den Faserkuchen zur Trocknung. Es entsteht ein ausserordentlich zäher, zunächst mehr papierartiger Körper, der   durch zweck-   entsprechende   maschinelle     Behandlung   in ein filzartiges Gebilde übergeführt wird. 



   Beispiel 11 :
Man entbastet, wie bekannt, Seide, wäscht das Material gut aus, schlämmt mit Wasser an,

  Process to make silk feltable.



   The process is due to the egg-like character of silk and its swellability and partial dissolution capacity in cold formic acid, without further splitting of the fibroin molecule.



   Example I: Small-fiber silk (silk waste) is deburred according to known methods, treated with cold water until the fiber is well washed out, slurried with formic acid until a uniform fiber egg is formed, these are placed on suitable sieving devices which allow the formic acid to run off and bring it down then the fiber cake for drying. The result is an extraordinarily tough, initially more paper-like body, which is converted into a felt-like structure by appropriate mechanical treatment.



   Example 11:
As is known, silk is deboned, the material is washed out well, and washed with water,
