Novel alkali preparation device for alkali used for yarn mercerizing

Abstract

The invention provides a novel alkali preparation device for alkali used for yarn mercerizing. The device comprises a mercerizing machine and an alkali preparation pool, waste alkali in the mercerizing machine is recycled into a waste alkali storage pool, wool yarns in the waste alkali are filtered out through a wool yarn filter, the filtered waste alkali continues to be prepared in the alkali preparation pool, alkali liquid is conveyed to the mercerizing machine again via a cooler, and then the cyclic utilization effect is achieved.

Description

technical field [0001] The invention relates to the field of yarn production, in particular to an alkali mixing device used for yarn mercerizing. Background technique [0002] In the production of yarn, it is usually necessary to put it into a mercerizing machine for dip-dyeing, so that the quality of the yarn can meet the processing requirements. The liquid used for the dip-dyeing is liquid alkali, and the concentration of liquid alkali directly affects the quality of yarn dip-dyeing. At present, The alkali mixing device provided for the mercerizing machine has three disadvantages: 1. The concentration of the alkali is sometimes high and sometimes low, and the concentration stability is poor. In the comparison process, it is easy to cause the liquid caustic soda to overflow the soda dispensing pool due to the excessive input of liquid caustic soda, resulting in waste of cost, and also causing harm when splashed on the human body. 3. Secondary recycling efficiency of spent c...
