Cook to practice the quality of the yarn to the capillary effect as the inspection standards, general requirements for the capillary effect of the average above the
(3) yarn scouring instance:
① clear boiled yarn: Yuan Gong dyed yarn using sulfide yuan (green) stained denim to curing Blue Ransha, reduce pigmentation, red muscle, neither alkali cooking stained shade, but the fastness somewhat less. Clear boiled yarn without any chemicals, you can put in
② lye boiled yarn: pure cotton with caustic soda (100%) 12 ~
2 bleaching yarn cotton yarn chlorine bleach-based. Chlorine bleach can be poured bleach method, continuous chain method, crawler law bleach. Poured bleach yarn piled up in the pouring bleach inside the drift fluid pump out from the yarn above the shower, and cyclic, is the intermittent production. Discount Decorative House Flags The chain method is hank sets strung together a chain-like, chain yarn continuously in sequence through the drift of liquid pool → pool → pickling tank → pool → dechlorinated pool → → washing pool demolition chain → dehydration → with white. This method is very high yield. Tracked method, also known as the rejection of the drift method, the yarn is divided into half a pack a set of triangular rods of stainless steel, Discount Decorative Garden Flags rod end is equipped with the pinion when the pinion tooth pattern board into the car body produced before and after rotation, cotton yarn and thus bleach evenly, will not cause the chain yarn knot macula. The whole car by the track shoe drive into the horizontal line moves forward, the device including bleaching the pool, take the air pools, ponds, acid pools, ponds, and dechlorinated pool, washed with white pool, the pool can automatically cycle feeding high degree of mechanization .

Bleached yarn and cotton cloth chlorine bleaching process is similar. Discount Decorative House Flags Concentration of available chlorine: pouring bleach solution with chlorine concentrations of 0.8 to
Bleached yarn quality should be white, uniform, no stains, no spots, no residual chlorine, the yarn surface pH of 7 to 8, the yarn breaking strength of not less than 96% of the bleach before. Sports Team Feather Flags
(3) the purpose and effect, and the cotton of yarn mercerized yarn mercerized mercerizing conditions are basically the same. Mercerized uniform or not directly affect the quality of staining. Discount Decorative House Flags
(1) yarn mercerized equipment: yarn mercerizing equipment arms hank mercerizing machine and rotary hank mercerizing machine, the former small footprint, which yields.

Automatic arms type hank mercerizing machine mercerizing operation, first prepared in advance and cooled to a certain temperature, the mercerizing solution flourished in the disk of the alkali, will be pre-prepared skein set in the roller, start the mercerizing machine, roller distraction to the required distance from the When alkali disk rises, the yarn that is, immersed in the mercerizing solution, rotation in the roller, steering interchangeable. Roller tension in this process, Discount Decorative House Flags first relax a little later to restore the original tension. Roll while the pressure required to put pressure on a roller. After clockwise 1 min, 1min after reverse the roll to stop pressure on alkali disk that decline. Custom Made Wind Flags When the water tray to move to the bottom of the roller, spray pipe began to spray warm water roll has returned to put pressure. After a certain period of time the spray rinse, the water pipe to stop the spray, roll stop to put pressure on the roller stops rotating at the same time remove the water tray, roller simply that close to each other. Hank is removed from the roller, and for pickling.
