What is the solvent used to dissolve cotton fibers?

Explanation:

The 70% acid can be used to discriminate reconstituted cellulose fibers from cotton and other natural cellulose fibers. At 45 °C, 75% zinc chloride solution dissolves acetates, triacetates, acrylics, silk, cotton that has not been mercerized, and rayons (cuprammonium and viscose).

Cotton will be dissolved in a 70 percent solution of H2SO4 (SULPHURIC ACID) Solution. (water 30 parts and Sulphuric acid 70 parts)The process is known as carbonization.

The method is used to identify the percentage of cotton in Polyester cotton blends by dissolving cotton in sulphuric acid solution and weighing and measuring the polyester values. Polyester remains unchanged in acids.

Adding one advantage of dissolving cotton:_

Burnout prints are also popular, which are printed on polyester-cotton blended fabrics with carbonizing the cotton and which results in beautiful impressions. The material must be polyester rich like 60/40

Caution: In burn out, prints recipe will not be precisely the same
