③ chainless mercerizing machine: structural differences with the first two mercerizing machine, Custom Made Garden Flags it has no padding device and stretched increase device. Fabric dip alkali and alkali in the long tank, the tank more than one above each other, rolling pressure straight stick, the last row of the package with alkali-resistant rubber bottom row is active cast iron roll, surface engraved with the outward rotation of the sub- wire lines, to prevent fabric shrinkage, Custom Made Garden Flags since the expansion rate effect. Cast iron roller immersed in the mercerizing lye, work through fabric between the upper and lower two rows of straight roll into a wavy, Baptist alkali time in the soft and hard rollers rolling point asked the rolling fluid twice. Fabric after the lye dipping tank after rolling through a heavy-duty pick-excess lye, and then after the alkali tank to alkaline Box peace bowl to complete the mercerization process. Chainless mercerizing machine is to use the fabric to the fabric tension and leaching of alkali and contractile force, so that the fabric close to the surface of the chainless, Custom Made Garden Flags relying on the friction between them to prevent the contraction of the fabric weft stretching rate is less effective. Chainless mercerizing machine can double the rate of production, higher yield, leaching of alkali for a long time, Advertising Feather Flags And Banners absorbed through the mercerizing, does not produce the broken edge, small footprint, easy to operate, is mainly used for polyester textile material mercerized cotton fabrics difficult to meet the requirements due to pieces of cloth, generally not a straight roller machine mercerized.
The mercerized method, (2) Backpack Flags cotton mercerized method and its work arrangements and a variety of fabric mercerizing, dry Busi light, wet mercerizing light, hot alkali mercerized, dyed mercerized and mercerized method. Currently the largest application in the production is still dry the Busi light method, rolling water, Wind Flags Advertising drying, Custom Made Garden Flags dry cloth and then mercerized fabric bleaching. Respiratory alkalosis homogeneous, dry cloth and rolled alkali lye concentration decreased less easy to control and recovery. First exposure to concentrated lye dry Busi light, dry cloth surface, so that the fabric surface swelling, the lye difficult to penetrate into the fabric core, Teardrop Flags And Banners causing the surface of mercerized mercerizing extent uneven. Wet mercerizing light for dry Busi light the inadequacies of the fabric introduced in the rolling water concentrated alkali slot, because the fabric contains a certain amount of water, concentrated alkali easily through the core, the mercerizing uniform, eliminates the need for pre-drying process, but a damp cloth requires squeezing uniform, rolling I rate the lower the better, in order to avoid concentration of mercerizing lye excessive dilution, affecting the light alkali recovery. Wet the Busi light effect less in the dry the Busi light, stained semi-finished hard to grasp. Dyed mercerized due to the small number of dyes used only for dyeing dye fast, easy to make dye unevenness, or some easy to be scratched in the mercerized fabrics, but the process route reversal, can not play mercerized dyeing can save the dye the advantages and mercerized light alkali dye stain, is not conducive to recovery, can not be mercerized to eliminate wrinkles in the pre-treatment bar, on the whole more harm than good.
(3) factors of the impact of mercerized Custom Made Garden Flags
① alkali concentration: only when the alkali concentration reaches a critical value, can cause intense puffing of the cotton fiber. Caustic soda concentration of 100 ~
