After the official enriching calico calico _ _ tabby calico paint provided by the official enriching. Calico, after the official enriching cloth, polyester cloth factory is PEG molecular weight and the amount of the Changyi City, Shandong Province, the official Fumin Textiles Limited (www.fumintex.com) 2014 been newly upgraded launched on printed fabric K / S values Effect of cellulose fibers under high temperature conditions, does not appear between the macromolecular chains of molecular diffusion of dye into the fiber available for transient pores inside, and less moisture in the fibers. It was found that polyethylene glycol ether bond many macromolecules, can be adsorbed by the surrounding water molecules, can be used as the absorbent cellulose fibers humectant. Padding polyethylene glycol solution to cellulose fibers under high temperature conditions, water molecules are not easily evaporate, but in the interior of the fibers forming the crystal structure of the frame, the presence of a large number of pores of the fiber, which provides for the entry just disperse conditions. Using this principle, select a different molecular weight and the amount of polyethylene glycol (PEG) solution for pre-modified cotton fabric (DS = 0.097) be printed pretreatment, and then choose Disperse Red E-4B transfer paper, by 1.4 be printed, to compare the quality and concentration of polyethylene glycol molecules and the impact on K / S values, modified printed fabric K / S values ??first increased and then decreased with increasing the amount of polyethylene glycol was, and polyethylene molecular weight diol, the higher the printing fabrics pretreated K / S values. Due to the presence of hydroxyl polyethylene glycol molecule only the ends, so the greater the degree of polymerization of paint calico tabby lower hydroxyl content and water absorption can be far stronger than the hydroxyl ether bond, so the low molecular weight polyethylene glycol molecule absorption capacity stronger and more absorbent macromolecules around, puffing effect is remarkable. Moreover polyester cloth scattered improve the amount of polyethylene glycol and molecular mass, its solution viscosity increased calico, decreased mobility when padding pretreatment agent, polyethylene glycol molecules is difficult to penetrate inside the fiber. After drying, due to the polyethylene glycol content in the lower rotary dispersion fiber cloth, fiber less water molecules, thus impeding the diffusion of dyes into the fibers. Molecular weight polyethylene glycol are used in the following test 200. Since the FS-200 can print high-resolution pattern thickener and has seepage ability, so will it be used for high-resolution printing, fine lines, dark printing blank large area, high percentage of polyester cotton fabric printing and improve some hold aqueous thickener has a very important practical significance. In recent years, with the increase in rotary screen, flat screen printing equipment, will be more conducive to the application and development of pigment printing technology, and alternative synthetic thickener emulsion paste modulation thixotropic paste has a better, more suitable for Pigment printing in the screen printing.
