(C) after dyeing treatment
The colored yarn. Washed color with a color lakes, Printable Race Car Flags and the color bath residue, and the neutralizer or alkali metal salts or hydroxides. The attached color lakes will reduce friction and wet fastness of dyed yarn, attached color Yu residue, dyed yarn drying release of hydrochloric acid, resulting in colored yarn strength decreased, so the purpose of washing is to remove the residual substances. Printable Race Car Flags Washing can be 70 ~
Soap boiling soap cook purpose is to enable the dye to the crystallinity of cotton fibers or the formation of large crystals, in order to improve color, brightness and sun, friction and wet fastness. General yarn of soap cook just once, if the yarn color is deep or more floating color, you can soap boiled twice. Soap boiling should pay attention to not allow direct steam impact of yarn, and it is not Printable Race Car Flags boiling over drama, in case of cotton yarn become loose or chaotic yarn.
(D) reciprocating yarn dyeing machine rendering and color of the yarn dyeing process of cotton yarn equipment reciprocating yarn dyeing machine, jet yarn dyeing machine or handmade yarn dyeing. Outdoor Decorative Flags Using reciprocating yarn dyeing machine base, requiring the appearance of pale white gauze in front of the base, no stains, must stretch the yarn straight and loose sets of rods to be smooth to prevent the yarn overlap. Free alkali concentration in the base bath should be based on the staining properties of Naphthol control, when the yarn into the base fluid, the yarn must be completely submerged in the base fluid, and swing back and forth to 7 ~ 10min appropriate . Yarn backing out the tank, drain 2 ~ 3min, and then wrapped in cloth with centrifuge dewatering, the moisture content of the base yarn is controlled in 65% to 70%. Yarn through the backing, Printable Race Car Flags can be stretched loose string lever color. The base yarn color you want to adjust the pH value of the dye bath ratio and temperature of the bath, the base yarn must be completely immersed in the color liquid, Discount Decorative Garden Flags and continue around the rotary and swing around to evenly pipette. Color-based coupling speed, reaction time can be controlled within 5 ~ 1Omin. The color is completed, full washing on dyed yarn, dehydration, bundled, stretched dry and drying, you can stain the finished product.
Five, polyester blended yarn dyeing
Disperse dyes is a simple structure, and strong hydrophobic non-ionic dyes, mainly used for dyeing of polyester and blended yarn. Requirements are different, the dye can be divided into two kinds of general and high-temperature dyeing properties and sublimation fastness. General type of disperse dyes dyeing, bright color, sublimation fastness in general, apply to carriers and high temperature and high pressure dyeing; high temperature dyes of high sublimation fastness, levelness and less, and more applications requiring resin finishing and curing process of yarn dyeing. Beachflags Polyester and blended yarn of high temperature high pressure dyeing, pretending to be the highlight.
(A) before transfection pre-shaped handle polyester blended yarn in Printable Race Car Flags the relaxed state of about 7% shrinkage in boiling water, Garden Flags Manufacturers when the temperature to 130 ° C, the shrinkage of up to 10% to 15%, so when using
