- the invention has Example for an object to increase the strength of the insolubfli ed protein filaments
- the insolubilisation of the coagulated wet spun is p o a c agulating bath consisting of an protein filaments can be most efiectively or conaqueous Solution containing phuric acid veniently carried out by means of formaldehyde and sodium sulphate at 30 C.
