Embodiment 1

[0041] The first water tank to the sixth water tank are each equipped with a suction pump to extract the liquid in the water tank, and the suction pump is correspondingly connected to the spray device 4 in the water tank, and each water tank extracts the liquid from the water tank The liquid inside sprays the cloth.

Embodiment 2

[0043] The fifth water tank 5 is provided with a main suction pump for extracting the liquid in the water tank. The spray devices from the first water tank to the fifth water tank are connected through a common dry road, and the main road is connected with the main suction pump. That is, spray the cloth width passing through the first to fifth washing tanks with the liquid with higher concentration of medicinal solution in the fifth washing tank. The sixth washing tank 6 is provided with a clear water suction pump for extracting the liquid in the washing tank, and the clear water suction pump is connected to the spray device in the sixth washing tank.

[0044]The above two examples were carried out in actual production respectively, and compared with the traditional process before technical transformation, the material consumption, energy consumption and production time were obtained in the following table. The data in the table is calculated by producing one ton of mercerized...

Abstract

The invention discloses a residual alkali neutralizing device for mercerizing. The residual alkali neutralizing device comprises an alkali liquor groove with concentrated alkali, an expanding faller and six washing water grooves arranged behind the expanding faller, the sixth washing water groove is communicated with tap water through a flow velocity adjustment valve, the fifth washing water groove is communicated with a liquid medicine cylinder through a flow velocity adjustment valve, and liquid in the next washing water grooves overflows into the previous washing water grooves. An operationtechnology of the device includes the following steps that a cloth with a width is subjected to concentrated alkali treatment in the alkali liquor groove and stretched to increase the width on the expanding faller, and sequentially enters the first washing water groove and the fifth washing water groove, meanwhile, residual alkali is diluted and neutralized, and the cloth with the width enters the sixth washing water groove to be rinsed with clear water. According to the device, the six washing water grooves formed in a mercerizing machine are sufficiently utilized, the process of neutralizing is executed in advance at the mercerizing machine, a dye vat or a full width washing water machine is omitted, on the premise of guaranteeing effective alkali removal and uniformity of all parts ofthe cloth with the width, water and electricity are saved, production efficiency is improved, energy saving and consumption lowering are easy, and efficiency is improved.

Description

technical field [0001] The invention relates to a mercerizing residual alkali neutralization device and an operating process thereof, belonging to the field of cloth dyeing and finishing. Background technique [0002] Mercerizing is a process in which the fabric is treated with a concentrated caustic soda solution under tension, and then washed to remove the caustic soda under tension. After the concentrated alkali treatment of the knitted fabric, the fabric should be washed and neutralized in time, otherwise the mercerized knitted fabric will have quality problems such as alkali spots and uneven dyeing in the subsequent dyeing and finishing process. In the prior art, the treatment of residual alkali after the mercerizing process includes two steps, namely water washing and neutralization. The water washing is to add hot water to the six washing tanks that come with the mercerizing machine, so that the cloth passes through the six hot water tanks in sequence; The neutraliza...
