Colored spun yarn coloring machine capable of preventing fibers from length contraction due to water absorption

Abstract

The invention discloses a colored spun yarn coloring machine capable of preventing fibers from length contraction due to water absorption. The colored spun yarn coloring machine capable of preventingthe fibers from length contraction due to water absorption structurally comprises yarns, a pay-off device, a machine body, a driving device, a take-up device, a support frame and a shock absorption support, wherein the bottom of the machine body is mechanically connected with the support frame; and the pay-off device is mounted on one side of the machine body. Compared with the prior art, the colored spun yarn coloring machine capable of preventing the fibers from length contraction due to water absorption has the beneficial effects that the colored spun yarn coloring machine is provided witha plurality of stations, a plurality of single yarns can be colored at the same time, the coloring time is short, the speed is high, a whole roll is prevented from being dipped and dyed, the coloringis uniform, pay-off dyeing and the coloring take-up are synchronous to apply certain tension to the yarns, the fibers are effectively prevented from length contraction due to water absorption, the effective diameter is prevented from being increased, the dyeing time is greatly shortened, the yarns expanded after coloring can be squeezed, extra dye is further squeezed out, the yarn dyeing concentration is effectively prevented from being too high, and dyestuff is saved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a colored spinning coloring machine for preventing fiber water-absorbing length shrinkage. Background technique [0002] Due to the new process of "dyeing first, then spinning", the color spinning shortens the production process of the downstream processing enterprises, reduces the production cost, and has high added value. Compared with traditional crafts, it saves water and reduces emissions by more than 50%, and meets the requirements of low-carbon environmental protection, so it is worth advocating. [0003] Existing dyeing of color-spun yarn mostly uses the whole roll of original sand roll for dip-dyeing. In order to fully dye the inside of the original sand roll, the dip-dyeing time is longer, which easily leads to high external solubility and low internal solubility, resulting in incomplete dyeing. In addition, colored spinning yarn is made of fiber material, and the fib...

Problems solved by technology

[0003] Existing dyeing of color-spun yarn mostly uses the whole roll of original sand roll for dip-dyeing. In order to fully dye the inside of the original sand roll, the dip-dyeing time is longer, which easily leads to high external solubility and low internal solubility, resulting in incomplete dyeing. In addition, colored spinning yarn is made of fiber material, and the fiber has strong water absorption, so more dyeing solution is needed, and the fiber will swell when it absorbs water in water, and the swelling will cause the length of the yarn to shrink and the effective diameter to increase.
