I. Introduction High temperature high pressure dyeing polyester fiber is an important staining methods, as polyester fiber dyeing properties and high temperature high pressure dyeing special way, also unusual for the high-temperature leveling agent for dyeing with the special requirements and also due to the textile semi in the form of class differences, further high-temperature leveling agent had a different special character requirements. Therefore, in addition to 130 have adapted to retarding high temperature conditions, such as the fundamental basis for transfer dye other than performance, there should be found in various types of polyester fiber dyeing characteristics of semi-specific varieties, otherwise, the specific application will be difficult to good for high temperature high pressure dyeing different types of personality characteristics, so the applicability of greatly reduced. Second, different fiber types of different staining characteristics of semi Textile semi polyester fiber type, also were scattered fibers, yarns, fabrics and other forms. Loose fiber dyeing required for the color spinning, yarn dyeing mainly for weaving, followed for sewing, embroidery used; fabric dyeing, the Department for garments, home textiles, industrial fabrics and other requirements. Fabric dyeing, it is also divided into a loose-type dip, width and beam jigger dyeing, and other means. Although the high temperature and pressure are used as methods of dyeing, but different forms of fiber semi, found their form must match the characteristics of different dyeing equipment; otherwise, it will obviously make textiles in style, features, and product quality seriously damaged, and no staining or even the feasibility in terms of As. Slack dip machine is suitable for weft and warp knitted class, and wool-like style of the woven fabric. Jig width requirements for inelastic woven fabric, especially for the filament-type class emulation Silk fabrics, such models are generally not non. The grid class of sloppy type warp knit fabrics (such as mosquito nets, etc.) A trans-axis dyeing machine is suitable. Yarn is mainly cheese or cage fitted dyed yarn means, although scattered fibers are also used for dyeing equipment cage method, but with yarn dyeing equipment cage also has a rather different form. Third, the basis of high-temperature leveling agent functions and individual requirements 3.1 High temperature leveling agent based functions: Hydrophobic disperse dyes suitable for dyeing hydrophobic polyester fibers, but the hydrophobic nature of the dye determines its low water solubility. This water as medium in the dyeing process, it should be said is a more contradictory nature of things. To this end, products disperse in large numbers to fight infiltrated by the ratio of not less than the spread of dye surfactant agent. General for the dye: filler = 1:1 ~ 1.5. Work as a dye bath and add another high-temperature leveling agent, which also has a supplementary and complementary role to promote the work of dyeing bath in the suspended particles disperse proliferation state, to maintain uniform and stable distribution. This relatively small amount of light dye, the color class is especially important, because light, in the amount of the corresponding class color dyes less from the dye into the proliferation of agents also simultaneously reduced the need for high-temperature leveling agent provide some offset of. Dyeing levelness, need to have the ideal retarding functions, which all the functions of leveling agent must have priority. However, the disperse dyes for dyeing polyester fibers, needs to tie in with the strong dye transfer function, because disperse dyes in polyester dyeing, from beginning to end and not a chemical reaction; and close polyester fiber structures, and the extreme tightness of the surface crystal layer and so on, played a key blocking, dyeing, you can move up retarding the vacancy on the one hand, especially to reach 130 heat dyeing stage, the dye in the dye bath has been most dye to the fibers, retarding feature has been basically completed the mission, dye transfer function at this stage has become a major role, it can further promote and guarantee the overall goal of leveling agent on the effect. Therefore, retarding, pollution and help shift the proliferation of co-portfolio into high-temperature leveling agent based on the most fundamental elements, but also in the use of different types of dyeing machines are required for basic functionality. 3.2 Individual requirements of the analysis and classification: Different dyeing machine to run the different staining methods, and then also had a leveling agent for high temperature requirements for personalization. The basis of the above essential functions that need low-foam type, respectively, anti-precipitation type, such as enhanced permeability differences between individual species to form a special series. 3.2.1 Low foam type and its applicability: I am an expert from diefeiltd.com, while we provides the quality product, such as China Butterfly Valve Manufacturer , China Pvc Butterfly Valve, Wafer Type Butterfly Valve,and more.
