Claims
- 1. A method for the shrink-proof treatment of a natural cellulosic fiber textile, comprising the steps of:treating the fiber textile with liquid ammonia, thereby converting the cellulose I or II crystalline structure in the fiber textile to cellulose III crystalline structure so that the content of cellulose III crystalline structure in the fiber textile is 10 to 35% based on the entire crystals, and treating the fiber textile under tension or under no tension with hot water at a temperature of 100 to 150° C., thereby obtaining a natural cellulosic fiber textile having a minimal shrinkage after washing.
- 2. The method of claim 1, which further comprises treating the fiber textile with a resin after the hot water treatment.
- 3. The method of claim 2, wherein the resin treatment uses formaldehyde.
- 4. A method for the shrink-proof treatment of a natural cellulosic fiber textile, comprising the steps of:treating the fiber textile with liquid ammonia, thereby converting the cellulose I or II crystalline structure in the fiber textile to cellulose III crystalline structure so that the content of cellulose III crystalline structure in the fiber textile is 10 to 35% based on the entire crystals, and subsequently treating the fiber textile under tension or under no tension with hot water at a temperature of 100 to 150° C., thereby obtaining a natural cellulosic fiber textile having a minimal shrinkage after washing.
- 5. The method of claim 4, which further comprises treating the fiber textile with a resin after the hot water treatment.
- 6. The method of claim 5, wherein the resin treatment uses formaldehyde.
