Direct printing is the easiest of all printing methods and the use of the most common form of printing methods. According to the different requirements of flowers, direct printing can get three effects, namely white ground, ground floor and color. White, that is part of the area is small calico printing, white part of the large area; Montreal spent most of the area is the fabrics are printed with color; colors to spend a good colored dyed, then printed pattern, ie willow flower district Wan method called overprint. She dyed printed under the hood, including AI technology officer still. Rhyme twist with disabilities have the same tune hB He Yue extension attached to spend as much as the bare indeed. The following describes the direct printing of various dyes. PEG molecular weight and the amount of printed fabrics K / S value of Cellulose fibers under high temperature conditions, not only does not occur between the macromolecular chains of the 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, which can absorb large amounts of water molecules around, absorbent cellulose fibers may be used as humectant. Padding polyethylene glycol solution to cellulose fibers under high temperature conditions, water molecules are not easily evaporate dispersion cloth, 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 happens to disperse Providing entry conditions. Using this principle polyester cloth prices, select a different molecular weight and the amount of polyethylene glycol (PEG) solution of the modified cotton fabric (DS = 0.097) performed pretreatment rotary screen printing calico dispersed, then choose Disperse Red E -4B transfer paper, printing carried out by 1.4, in order to compare the quality and polyethylene glycol molecule concentration and the impact on K / S value, modified printed fabric K / S values ??with increasing the amount of polyethylene glycol was first the rising and falling trend, and polyethylene glycol molecular weight, the higher the printing fabrics pretreated K / S values. Since only the presence of polyethylene glycol molecules hydroxyl ends, the degree of polymerization, the lower the hydroxyl content, and the absorbent can be far stronger than the hydroxy ether bond, and therefore a strong low molecular weight polyethylene glycol of molecular mass absorption capacity of macromolecules absorbing around much, puffing effect is remarkable. Furthermore, increasing the amount and molecular weight of the polyethylene glycol, the solution viscosity increased, decreased mobility, when padding pretreatment agent, polyethylene glycol molecules is difficult to penetrate inside the fiber. After drying, due to lower polyethylene glycol content in the fibers, the fibers are less water molecules, thus impeding the diffusion of dyes into the fibers. Molecular weight polyethylene glycol are used in the following test 200. [Cloth], polyester cloth prices, enriching calico provided by the officer after officer enriching.
