Technical Field

The invention belongs to the technical field of spinning, and particularly relates to an anti-printing process of viscose/lyocell/cotton blended fabric.

Background

Although the research and development of synthetic fibers has become a considerable trend in the world today, cellulose fibers remain the most dominant textile raw material due to their excellent natural comfort and unique physicochemical properties. The multi-fiber component cellulose fiber blended fabric integrates the advantages of different fibers, has complementary advantages and is a future development trend. However, the reactive dyes have very different dyeing properties for different fibers due to the different aggregation structures of different cellulose fibers. For example, viscose has a lower crystallinity than lyocell and cotton, and has a higher content of dye-absorbing amorphous regions, whereas cotton has a higher crystallinity than viscose and lyocell without mercerization, up to 70%. Meanwhile, because cotton fibers have more natural impurities, the impurities need to be removed through pretreatment so as to be beneficial to printing and dyeing. However, since viscose and lyocell fibers tend to lose strength and fibrillate under strongly alkaline conditions, the removal of impurities by strong alkali is not suitable for the three fiber blend fabric. And due to the sheath-core structure of viscose and lyocell, the dye has a great difference in the dyeing speed of the three fibers. Therefore, the blended fabric of the three fibers is printed, so that a product with uniform color is difficult to obtain, and the difficulty of printing prevention is higher. Many types of dyes can be covalently reacted with cellulose fiber structures based thereon. Reactive dyes have become the most common dyes for printing cellulosic fibers with their superior wet fastness and color gamut. However, conventional reactive dye printing has many problems of unused reactive dye, unfixed, and hydrolyzed. These problems stem from the fact that the reactive dyes and the moisture-containing cellulosic fabrics simultaneously have a negative charge, which results in a poor affinity of most cellulosic fabrics for reactive dyes.

With the demand for cleaner, lower cost textile products, improved reactive dye viscose/lyocell/cotton printing processes have been developed. The new process gives full play to the printing performance of the existing dye to the utmost extent, and chemically modifies viscose/lyocell/cotton fabrics to make the viscose/lyocell/cotton fabrics have positive charges. Because the cationic groups are implanted into the viscose/lyocell/cotton fibers, the affinity between anionic dye molecules and the viscose/lyocell/cotton is greatly improved, and the utilization rate of 100 percent of reactive dye becomes possible. The novel printing process is needed by the current society because the utilization rate of the dye is improved, the production cost is reduced, and the harm of the dye wastewater to the environment is reduced. The most commonly used cationic agent is 3-chloro-2-hydroxypropyl trimethylammonium chloride, based on good reaction efficiency and low cost as a screening basis. Although the new process improves the dye utilization rate, because the viscose/lyocell/cotton fibers are implanted with the cationic groups and are positively charged, the negatively charged dye molecules are very easy to be compatible with the white ground of the viscose/lyocell/cotton fibers during the washing process of cloth, so that the white ground is stained, and therefore, the development of the anti-staining treatment process for preventing the stain is also necessary.

In the traditional printing-proof process of the reactive dye viscose/lyocell/cotton fabric, the monochlorotriazine type dye can be fixed on the fiber only under the alkaline condition, so that nonvolatile organic acid or acid salt can be used as a dye-proof agent, and for the vinyl sulfone type reactive dye, the sodium sulfite acts with the reactive dye to lose the capability of reacting with the fiber, thereby achieving the printing-proof purpose. However, on the viscose/lyocell/cotton fiber after the cationic group is implanted, because the positive charges on the viscose/lyocell/cotton fiber have electrostatic attraction to the negative charges of the sulfonate group of the reactive dye, dye molecules in the novel printing process are very easy to be compatible with the viscose/lyocell/cotton fiber, so that the anti-printing effect of the traditional process is obviously reduced, and a new anti-printing process needs to be found.
