Benefits of technology

The invention uses an extrusion process to make milk protein fibers, which can be used as textile fibers. This process helps to remove substances that are harmful to health and the environment, saving money and resources and improving environmental protection. The fibers have solidifying changes during plasticizing, which make them suitable for textile applications. The technical effects of the invention are improved safety and efficiency in the production of milk protein fibers.

Problems solved by technology

The pollution level provoked by the coagulation bath and the consumption of water are very high.
Furthermore, this method requires a lot of time, the process time is about 60 hours.
This leads to longer production times and an additional energy demand.

[0037]Production of a milk protein fiber having a strength of 20 dtex. The extrusion is realized by a single-screw extruder type 30 E of the company Dr. Collin having a diameter of 30 mm. The heating is realized by four cylinder heating zones with the following temperature development: 65° C., 74° C., 75° C., 60° C.:

[0038]The casein powder is supplied via a vibrating conveyor. The water is added in a proportion of 1:2 (water:casein) by means of a peristaltic pump. The fiber strength is defined by the jet strength. The fiber can for example have a strength of 20 dtex. The fibers are wound up by means of a winding machine and dried at room temperature.

Abstract

Milk protein fibers are produced by an extrusion process for the textile industry inter alia, in which at least one thermoplasticizable protein obtained from milk is plasticized with a plasticizer, for example water or glycerol, at temperatures between room temperature and 140° C., under mechanical stress and spun to fibers by means of a jet.

Description

[0001]The invention relates to a method for producing milk protein fibers, inter alia for the textile industry and hygiene and medical products, and to the associated milk protein fiber products such as cotton wools, fleeces, loose short fibers, yarns, woven and knitted fabrics as well as other products manufactured by means of the fiber according to the invention.STATE OF THE ART[0002]Milk protein fibers belong to the protein fibers which in the widest sense also include the natural products wool and silk. Protein fibers have been known for a long time on the technical scale. Casein fibers were already produced in the thirties. Casein is a protein fraction from the milk of mammals. Casein is produced from skimmed milk which is brought to coagulation at 45° C. by means of acids at around pH 4.6 (the isoelectric point of casein). Alternatively, lab is used for the coagulation. The solid matters are separated or pressed off and washed several times. Finally, a drying at 50 to 80° C. i...
