Description

Process for the use of cleavage products of the protein bodies for felting in the felt and hat industry.

Addition to patent 330133. It is known from patents 330133 and 337151 that the use of the cleavage products of protein bodies, such as protalbine and lysalbinic acid and the like or their salts, in purified or unpurified form in dye baths is advantageous for the dyeing result and Especially in the case of wool, it protects the fibers. The same is the case with hair.

It has now been found that these protein breakdown products, preferably those of the patent 337151, in the hat industry except in dye baths when dyeing Materials, Labrazen or stumps also when bumping the felted compartments into Labrazen and can be used advantageously when milling the Labrazen into stumps, by if they are also used, the wool or hair when bumped or milled not attacked by the chemicals used, but on the contrary spared, d. H. protected, and even improved.

It is well known that sulfuric acid is used to felt hair and wool used. With this desired effect, however, there is another undesirable one Effect of chemicals on the substance of hair and wool together, such that the hair and wool lose their shine, become less elastic and brittle, as a result of which the goods get a rough and bad grip. According to the invention one should now the one used to toast the Labrazen and when walking the Labrazen into hat stumps dilute sulfuric acid or the dilute ammonia solution Protein bodies, such as protalbic acid and lysalbic acid or the like. Or their salts, in purified form or add uncleaned form, increasing the shine, softness and elasticity the hair and wool fibers are not only preserved, but even improved in a noticeable way will.

Example 1. Glycerin-spun felted sheds are thinned instead of with Sulfuric acid alone with water, which contains approximately equal amounts of protein decomposition products and conc. Sulfuric acid are added, toasted to Labrazen in the usual way.

Example 11.

Instead of using dilute ammonia alone, water to which about twice the amount of protein cleavage products as ammonia are added and which is kept alkaline by topping up with the same mixture is toasted in the usual way to make rennet, instead of using dilute ammonia. Example 111..

Instead of time-diluted sulfuric acid, labrazen are mixed with water, which the same amounts of protein breakdown products and conc. sulfuric acid are added, milled into stumps in the usual way.

Claims (1)

PATENT CLAIM: Process for using cleavage products of the protein bodies according to patent 330133 for felting in the felt and hat industry, characterized in that these cleavage products such as protalbinic and tysalbinic acid and the like or their salts, in purified or unpurified form in Community with the usual chemicals (sulfuric acid or ammonia) when touching felted hat compartments to Labrazen and when milling the Labrazen to hat stumps are used to protect the z. B, damage to the wool and hair caused by the sulfuric acid.
