K / S value is to evaluate the effect of fabric printing is an important indicator, it not only shows the color yield dispersion calico printed fabric shades and indirect characterization of disperse dyes on cotton fabric fixing case. K / S value is larger, the deeper the color printed fabric cloth wholesale dispersed 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 (transfer temperature 220 ℃, the transfer time of 26 s) performed on the modified cotton transfer printing . Modified by using different substitution degrees of cotton, cotton fiber compare the degree of substitution of hydroxyl K / S value of the dispersion effects twill cloth, K-modified cotton fabric after printing / S values ??increase with the degree of modification of cotton and hydroxy-substituted 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 disperse dye molecules with the fiber ring is aromatic 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. Our blended fabrics are dispersed in a variety calico prices early 1960s developed the fiber has a crisp, smooth, quick-drying, durable and other characteristics, the majority of consumers. Currently, the proportion of blended varieties have been from the original 65% polyester and 35% cotton, etc. become 65:35,55:45,50:50,20:80 blends various proportions, which are designed to adapt to different levels consumers.
