Description

Patented Oct. 18, 1932 neon :11.61), or KARLsnuHE, GERMANY PROCESS FOR- THE RECOVERY OF COCOS FIBERS No Drawing. Application filed March 25, 1929, Serial Ne. 349,909,-an'd in Germany March 27, 1928.
The cocoanut fibers usually obtainable in the trade are, as is well known, unsuitable for mechanical spinning in technical industrial establishments on account of their hardness 5 and small suppleness.
N ow it has been found that such fibers can be materially improved by treatment. with alkaline liquids at raised temperatures preferably at temperatures over 100 for eX-' v ample from 1:20 to 150 (3., rapidlyand at relatively small cost so that they become soft and elastic while retaining their breaking or. tearing strength, thus being made sultable stances. The alkaline liquids employed may. after use be conveyed to another container and after suitable regeneration for example,
by adding'sufiicient alkali to bring the solu- 39 tion up to 8%, and heating be used again, enabling thereby the cost of the process to be further considerably reduced.
It has already been proposed to treat the fiber padding of cocoanuts with hot dilute solutions for the recovery of the fibers. In this treatment, however, the fiber. does not become soft because the alkali present is used to open up thecork-like bedding layer of the fiber padding in largequantities and is thus rendered useless for softening the liberated fiber so as to make it suitable for spinning.
In accordance with this invention the novel discovery of the softening effect of alkaline liquids utilized in that already, isolated fi iers i. e., fibers freed from thebedding substance referred to and if need be also subjected to a cleaning process are treated with alkaline liquids in order thereby-to improve the fibers more especially for spinningby machinery.
The isolation of the fiber from the bedding substance thereof may be effected by means of various methods for instance by a preliminary dipping ef t1 e shell of the cocoanut in hot water while maintaining it in motion and thereafter subjecting it to a mechanical treat- '1 ding substances to the action of a weak alkaline solution maintained at a te1nperature above 100 C. in a closed container, for a period of less than one hour.
2. The process of preparing soft, supple, spinnable cocoanut fibers as defined in claim 1 in which the alkaline solution used is caustic soda and the time of treatment in the closed container is substantially twenty mi.nutes.
3. The process of preparing soft, supple, spinnable cocoanut fibers which includes, subjecting hard, raw fibers freed from bedding substances to the action of an alkaline solution of Etc 3% strength maintained at a temperature above C. in a closed container, for a period of less than one hour.
'4. The process of preparing soft, supple,
spinnable cocoanut fibers which includes subjecting hard, raw fibers freed from bedding substances to the action of a weak alkaline solution maintained at a temperature of C. to C. in a closed container.
5. The process of preparing soft, supple, spinnable cocoanut fibers which includes, subjecting hard, raw fibers freed from bedding substances to the action of an alkaline solution of 2 to 3% strength maintained at a temperature of 120 to 150 C. in a closed containerfi 6. The process of preparing soft, supple, spinnable cocoanut fibers which includes, subjecting hard, raw fibers freed from bed- 1 ding substances to the action of a weak alkaline solution maintained at a temperature above 100 C. in a closed container and finishing the softened fiber by treating it with oleaginous finishing substances.
7 The process of preparing soft, supple, v
spinnable cocoanut fibers which includes, subjecting hard, raw fibers freed from bedding substances to the action of a weak caustic alkali solution maintained at a temperature above 100 C. in a closed container and finishing the softened fiber by treating it with oleaginous finishing substances.
