Abstract
Partial carboxymethylation of cotton fibers was performed so as to bring about three levels of chemical modification cotton fibers were also treated with caustic soda solution of identical concentration to that used in partial carboxymethylation. The properties of the modified fibers were compared with those of raw cotton fibers as well as with alkali treated fibers with a view of signifying the effect of chemical modification. Main conclusions arrived at from these studies are given below:
1- Partially carboxymethylated cotton shows higher micron ire values as compared with raw cotton and alkali treated cotton particularly at higher level of chemical modification, but it is still lower than that of polyester fibers.
2- Both partial carboxymethylation and alkali treatment of cotton fibers are accompanied by a decrease in fibers length and length uniformity ratio.
3- There is a marginal decrease in fibers strength after partial carboxymethylation and alkali treatment.
4- Partial carboxymethylation of cotton fibers causes a significant increment in breaking elongation. It may increase from about 6.5% for raw cotton to about 14% for Hc, while it is 11% for Ac.
5- Moisture regain of partially carboxymethylated cotton is considerably higher as compared with raw cotton and alkali treated cotton. The moisture regain may be 7.3% for Rc and 7.8%for Ac, while it may increase to 9.7% for Hc.
from the studied carried out on the relations between the properties of individual components and their blend, the following conclusions could be arrived:
- Generally, there are no significant differences between theoretical and experimental values.
