Open-width alkali deweighting machine

Abstract

The invention belongs to the field of machines and particularly relates to an open-width alkali deweighting machine used in a polyester fabric alkali deweighting treatment process. The open-width alkali deweighting machine comprises a machine box, a fabric feeding device, a fabric discharging device, a treatment solution and a treatment solution heater, wherein the fabric feeding device, the fabric discharging device, the treatment solution and the treatment solution heater are arranged in the machine box. The open-width alkali deweighting machine is characterized in that the fabric feeding device and the fabric discharging deice are composed of guide rollers used for regulating the running speed of flat gray fabric; a down-pressing conveying continuous track and a gray fabric conveying continuous track which are used in a vertically matched mode are arranged in the machine box, the lower part of a continuous track body of the down-pressing conveying continuous track is arranged below the surface of the treatment solution in the machine box, prismatic protrusions are distributed on the surface of the continuous track body of the down-pressing conveying continuous track and / or a continuous track body of the gray fabric conveying continuous track, and the ridge direction of each protrusion is identical to the axial direction of the corresponding continuous track body. The open-width alkali deweighting machine has the advantages of reducing energy consumption, improving working efficiency, lowering labor cost and improving product quality.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an alkali weight reduction machine for polyester fabric alkali weight reduction treatment process. Background technique [0002] The alkali reduction process is mostly a process of treating polyester fabrics in high temperature and lye, using lye to hydrolyze and corrode polyester fabrics to promote the relaxation of fiber fabrics, reduce their quality, reduce fiber diameters, and form pits on the surface, making The fabric feels soft, has soft luster, improves moisture absorption and perspiration, and has a silk-like style, thereby achieving a production process for fabrics with a real silk feel. The commonly used alkali weight reduction machines are mostly rope-shaped alkali weight reduction machines. The polyester gray cloth entering the alkali weight reduction machine is rope-shaped, and enters the steam box of the alkali weight reduction machine through guide rollers. N...
