Abstract
The invention relates to a method for starching by utilizing ultrasonic waves. The method comprises the following steps of: (1) pouring starch into a starch tank, unreeling yarns from a warp beam, immersing the yarns in the starch tank directly, and opening an ultrasonic generator, so that ultrasonic oscillation is generated in the starch tank, wherein the bottom of the starch tank contains a plurality of ultrasonic oscillation points, and connecting holes arranged on one edge of a groove are connected with the ultrasonic generator; (2) allowing the yarns in the step (1) to pass through an immersion roller, and extruding by using a roll compacting roller, wherein a 'double-immersion and double-compression' mode is adopted in the integral sizing process; and finally, drying the obtain yarns. According to the method, the temperature of the starch tank is stabilized to 55 DEG C in the starching process, so that energy consumption is reduced, and low-temperature starching is realized; the starched yarns are stable in quality, and the starching rate is improved, so that the strength of the starched yarns is improved, and hairy feather is reduced obviously; and the wear-resisting property is improved, and the starch is high in penetrability and coverage in the yarns by the high moistening of fibers and the starch.
