Definitions
- My invention relates to a process for hardening fibrous protein material, such as fibres, filaments, threads, films and the like.
- the fibrous protein materials are treated with a methanal containing medium of elevated temperature, 1. e. at least above 70 C. for a short time. Excellent results are obtained by boiling the fibres, threads and the like for some time in an aqueous bath containing methanal. It is preferred to introduce the product gradually into the bath at this high temperature.
- Other substances may be added to the methanal bath such as for instance sodium chloride, magnesium sulfate, glycerol, glucose, etc. Particularly such substances may be added which form artificial resinous products with methanal and the incorporation of which into the protein fibres may be of importance for the properties of these fibres. Examples of such substances are urea, thiourea, phenol, and the like. When adding such substances as a rule a higher methanal concentration is necessary.
- the treatment may be effected in closed vessels andhereby application of temperatures above the normal boiling point is possible.
- this agitation may also be obtained by agitating the bath in other way, preferably by blowing in vapours or gases, such as for instance methanal containing steam.
- a methanal containing medium bath or atmosphere
- methanal containing medium I also mean a bath or atmosphere of substances yielding or splitting of methanal, such as paraldehyde, hexamethylenetetramine and the like.
- An example of a very suitable combination according to my invention is the following;
- Casein fibres freed of acid by washing are led into a bath containing 4% of methanal, 5% of sodium sulfate, 2% of sodium acetate in a proportion of 100 kg. of fibrous material to 1700 kg. of bath liquid.
- the temperature is raised to C. in 45 minutes.
- the fibrous mass is then maintained in the boiling bath for 15 minutes.
- the process of my invention is not only applicable to the casein mentioned but also to any protein of animal or vegetable origin suitable or rendered suitable for being spun and also to mixtures of one or more proteins with viscose;
- step 2 which consists in hardening the said material by contacting the a same with a methanal-containing medium by immersing the material in a methanal-containing bath at a temperature above 70 C. for a maximum of about one hour, and agitating the bath by blowing gas thereinto during such immersion.
- a process for hardening fibrous protein material which consists in contacting the said mamethanal and at least one alkaline salt at a temperature above 70 C. tor a maximum or about one hour.
- a process for harden-lng fibrous protein material which consists in contacting the said ma- .”terial with a-methanal-containing medium having a weak alkaline reaction, at a temperature ening the said material by boiling the same in a terial with a methanal-containing medium by immersing the material in a bath containing methanal-co'ntaining medium for a maximum of about one hour.
