Description

High-quality mercerizing equipment

Technical Field

The utility model belongs to the technical field of printing and dyeing equipment, and particularly relates to high-quality mercerizing equipment.

Background

As shown in fig. 1 and 2, in a conventional through-air tube mercerizing machine, two heavy padders are used for finishing repeated padding of fabrics at the front stage of mercerizing, and after each padding, the requirement for caustic soda action time is met by an through-air tube path, the through-air time after the first padding is longer and accounts for 60-70% of the action time of all through-air sections, and the through-air time is shorter for the second time. In order to optimize the mercerizing swelling effect, the liquid carrying amount of the fabric is generally required to be set high so that the fabric is fully soaked by the alkali liquor, but the amount of the caustic soda is increased, and therefore, the contradiction between the swelling effect and the caustic soda amount is difficult to reconcile. The nip pressure of the second padding is usually set higher for less caustic consumption to reduce the amount of caustic brought into the tenter and washed by the fabric, however, this has the consequence that the mercerization swelling effect is weakened and it is difficult to meet the demand of high quality variety for process effect.

Disclosure of Invention

The utility model aims to provide high-quality mercerizing equipment which can reduce the using amount of caustic soda and reduce the requirements on subsequent clip spraying and washing sections aiming at the defects of the conventional mercerizing equipment.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a high-quality mercerizing equipment, includes into cloth device, rolls alkali ventilation unit, cloth gripper tentering device, washing drying device and play cloth device in proper order, its characterized in that: the alkali rolling ventilation device sequentially comprises a first heavy padder, a first ventilating section, a second heavy padder and a second ventilating section; and a high-efficiency padder is arranged between the second ventilating section and the clip stentering device. Before the fabric subjected to alkali rolling enters a stentering washing process, the fabric firstly passes through a ventilation section with large liquid carrying capacity, and then is ventilated with a high-efficiency padder to carry out secondary liquid rolling on the residual caustic soda of the fabric, so that the liquid carrying capacity of the fabric is reduced, the requirements on subsequent cloth clip spraying and washing sections are reduced, the washing efficiency of the subsequent process is improved, the fabric in the previous process has high liquid carrying capacity, the fabric is fully soaked, and the mercerizing swelling effect is optimized.

It is further characterized in that: and a liquid receiving tank is arranged beside the high-efficiency padder. The high-efficiency padder rolls the surplus alkali liquor through the liquor receiving tank and receives the surplus alkali liquor to flow back to the impregnation tank, so that the use amount of the alkali liquor is reduced.

Further: the pressure of the second mangle is less than the pressure of the first mangle. The pressure setting of the two heavy padders is adopted, so that the large nip pressure is used for the first padding, the inner core air of the fabric yarn is completely squeezed out and then is forcedly soaked by the alkali liquor under the squeezing action of the roller, the lower pressure is used for the second padding, the fabric leaving the nip keeps sufficient liquid carrying capacity, and the mercerization swelling effect is optimized through longer acting time under the saturated soaking condition.

Further, the method comprises the following steps: the length of the second ventilation section is longer than that of the first ventilation section. Because the pressure of the first heavy padder is higher, the liquid quantity of the fabric belt is lower, the requirement can be met only by a shorter ventilating section, and the pressure of the second heavy padder is lower, the liquid quantity of the fabric belt is higher, and the longer ventilating section is needed.

Preferably: the first ventilating section and the second ventilating section comprise a plurality of ventilating rollers.

According to the utility model, the fabric subjected to alkali rolling passes through the ventilation section with large liquid volume before entering the stentering washing process, and then the efficient padder is arranged at the ventilation tail end to carry out secondary liquid rolling on the residual caustic soda of the fabric, so that the liquid volume of the fabric is reduced, the requirements on the subsequent clip spraying and washing sections are reduced, and the washing efficiency of the subsequent process is improved. Meanwhile, the pressure setting of the two heavy padders is adopted, so that the mercerizing swelling effect is improved by a method for improving the liquid carrying capacity of the ventilation section while the consumption of caustic soda is not increased in the production process.

Detailed Description

As shown in fig. 3 and 4, the high-quality mercerizing device sequentially comprises a cloth feeding device 1, a first heavy padder 2, a first ventilating section 3, a second heavy padder 4, a second ventilating section 5, a high-efficiency padder 7, a cloth clip stentering device 8, a washing device 9, a drying device 10 and a cloth discharging device 11. The first and second

ventilating sections

The pressure of the second double calender 4 is less than the pressure of the first double calender 2 and the length of the second ventilated section 5 is longer than the length of the first ventilated section 3.

When the mercerizing swelling machine works, the pressure setting of the two heavy padders is adopted, so that the larger pressure of the rolling point is used for the first padding, the inner cores of the fabric yarns are completely squeezed out and then are forcedly soaked by alkali liquor under the squeezing action of the rollers, the lower pressure is used for the second padding, the fabric away from the rolling point is kept with sufficient liquid carrying capacity, and the mercerizing swelling effect is optimized after the fabric is subjected to longer action time under the saturated soaking condition. The fabric after twice alkali rolling is arranged before entering a stentering washing process, and the residual caustic soda of the fabric is subjected to liquid rolling again through a high-efficiency padder, so that the liquid carrying amount of the fabric is reduced, the requirements on subsequent clip spraying and washing sections are reduced, and the washing efficiency of the subsequent process is improved.
