Abstract
Methods and systems for treating cotton yarn are provided. Cotton yarn is partially dissolved by applying a cold aqueous alkaline solvent, rinsing the partially dissolved cotton yarn in water and drying the cotton yarn. Temperature of the solvent and time of exposure to the solvent greatly affect the improved mechanical properties of the cotton yarn.
Claims16
A method of treating cotton yarn for improved mechanical properties, the method comprising:
- providing a predetermined quantity of cotton yarn;
- partially dissolving said cotton yarn by applying a first treatment of aqueous alkaline solvent at a predetermined rate for a predetermined period of time, said first treatment of aqueous alkaline solvent having a predetermined temperature;
- applying to said partially dissolved cotton yarn a treatment of water at a predetermined rate such that said treated cotton yarn is rinsed in said water treatment for a predetermined period of time;
- and
- drying said partially dissolved and rinsed cotton yarn.

A system for treating cotton yarn for improved mechanical properties, the system comprising:
- a predetermined quantity of cotton yarn;
- a yarn-pulling apparatus;
- a first bath of aqueous alkaline solvent configured such that said cotton yarn is soaked and partially dissolved when said cotton yarn is pulled through said first bath of aqueous alkaline solvent at a predetermined rate for a predetermined period of time, said first bath of aqueous alkaline solvent having a predetermined temperature;
- a bath of water configured such that said soaked and partially dissolved cotton yarn is rinsed when said cotton yarn is pulled through said water bath at a predetermined rate for a predetermined period of time.
