Moisture-absorbing and heating cotton fiber and its preparation method and application |
| abstract |
The invention discloses a hygroscopic heating cotton fiber and a preparation method and application thereof. The preparation method of the hygroscopic heating cotton fiber has the following steps: (1) In the presence of an esterification catalyst, an aromatic acid compound and an alcohol polymer compound are esterified The reaction obtains an ester polymer compound; the aromatic acid compound is an alkyl-substituted benzoic acid; the esterification catalyst is a cation exchange resin; ② cotton fibers and the ester polymer compound obtained in step ① are in the presence of an addition catalyst In the next step, the hygroscopic heating cotton fiber is obtained through an addition reaction; the addition catalyst is dry hydrogen chloride gas. By modifying the cotton fiber, the present invention makes the hydroxyl group on the cellulose react with the carbonyl group on the ester polymer compound to form a stable network structure, which greatly improves the bonding fastness of the cellulose and the polymer compound, thereby giving the cotton Fiber has better hygroscopic and heat-generating properties. |
