K / S value is to evaluate the effect of fabric printing is an important indicator, it not only shows the depth of printed fabric color yield, and indirect characterization of disperse dyes on cotton fabric fixing case. K / S value is larger, the deeper the color of the fabric printing new decentralized cloth, dye fixation rate is higher. In order to more accurately test the printed fabrics K / S values, the use of the whole earth trichromatic color type disperse dye transfer printing paper. With 10% PEG 200 solution of the modified cotton pretreatment with Disperse Red E-4B transfer paper, by 1.4 in the printing process (temperature of 220 ℃ scattered calico transfer, the transfer time of 26 s) of the modified cotton conduct transfer printing. Modified by using different degrees of substitution of cotton, the degree of impact on the K / S value is relatively dispersed calico cotton fiber hydroxyl substituted wholesale, K-modified cotton fabric after printing / S value with the modified cotton to improve the degree of substitution of hydroxyl and increases, and the linear relationship. This proves indirectly that the disperse dye fixing of cotton fiber must rely aromatic ring structure, and the surface of the fiber with disperse dye molecule is an aromatic ring one to one relationship, the aromatic ring directly determine the number of inter-fiber bonding strength of the dye and size. Degree of substitution (DS) value is large, the surface of the fiber aromatic content, dyes molecules fibronectin fixing points, the dye and the fiber binding force, fixing the dye quantity, K / S value is large; Conversely, K / S value is small. With the development of synthetic fiber industry, mass production of a variety of synthetic and blended fabric for pigment printing is also a challenge. Itself has no affinity for the fiber coating, an adhesive coating alone mechanically attached to the surface of the fiber dispersion quality cloth, forming a thin film, it is cured to form the colored pattern after a certain and fastness. Pigment printing on principle, it applies to all fiber printing, so the advantages of pigment printing becomes more prominent.
