Claims
- 1. A method for detoxifying raw cotton fiber without decreasing the processability of said fiber into yarns and fabrics comprising treating said fiber in a solution selected from the group consisting of: ethanol and sodium hydroxide, and dimethylsulfoxide.
- 2. The process of claim 1 wherein said solution is ethanol and sodium hydroxide.
- 3. The method of claim 2 wherein the ethanol is 95% ethanol.
- 4. The method of claim 3 wherein the solution is 95% ethanol and sodium hydroxide in proportions of from about 270-400: 1 ethanol to sodium hydroxide and the temperature is from about 60.degree. to 80.degree. C.
- 5. The process of claim 1 further comprising processing said fiber into yarns after said detoxifying step.
- 6. The process of claim 3 further comprising processing said fiber into yarns after said detoxifying step.
- 7. The process of claim 4 further comprising processing said fiber into yarns after said detoxifying step.
- 8. The process of claim 2 further comprising processing said fiber into yarns after said detoxifying step.
- 9. A method for detoxifying cotton fiber comprising treating said fiber in a solution of dimethylsulfoxide in proportions of from about 30: 100: 1 dimethylsulfoxide to cotton and the temperature is from about 60.degree. to 80.degree. C.
- 10. The process of claim 9 further comprising processing said fiber into yarns after said detoxifying step.
