Abstract
After polyester fabric is padded, the present invention uses microwave to implement alkali decrement processing method. It is composed of level pressure mangle, microwave cavity body equipment and water-washing equipment. Said invented alkali decrement method is quick in reaction speed, low in energy consumption, convenient for controlling decrement rate and low in industrial pollution.
Description
The present invention relates to a kind of method of the terylene fabric being carried out the alkali decrement.
The alkali decrement process is a topmost technology in the Productio of Polyester Silk processing, it be with NaOH to the polyster fibre hydrolysis, thereby make dacron soft, permeability increases, the style that drapability is good, have silk broadcloth.Studies show that, different dacron only under different decrement conditions, can reach ideal effect.Reduction rate is on the low side, and fabric feeling hardens, and can not reach the style of silk broadcloth; Otherwise then fabric intensity reduces, even causes fabric to scrap.Therefore, the control of reduction rate is the key in the alkali decrement process, and it has determined the quality and the style of Productio of Polyester Silk product.At present, domestic manufacturer adopts step process equipment, as hangs experienced groove decrement, machine cylinder decrement etc.Main reduction rate by range estimation or experience estimation fabric, so the technology instability, product quality is difficult to guarantee.The external more employing continous mode of dacron process equipment, it regulates the reduction rate of fabric by controlling the pick-up rate and the speed of a motor vehicle, but equipment investment is big, and the style of influence part product.Simultaneously, present dacron decrement all adopts Steam Heating, and the process time is long, power consumption is big, difficult control reduction rate, and the NaOH utilization rate is low, causes a large amount of sewage.
The objective of the invention is: provide a kind of microwave that dacron is carried out alkali decrement method.
Foundation of the present invention: the alkali decrement processing of dacron, essence is the heterogeneous hydrolysis that takes place between NaOH and the polyster fibre polyester polymer.Adopting microwave device, dacron is carried out the alkali decrement, mainly be that an end has negative electrical charge in the NaOH molecule, and the other end has positive charge, has produced the moment dipole of molecule when promptly the distribution of charges in the molecule is uneven.The unbalanced molecule of this distribution of charges sucks microwave energy under microwave action, and the quickening of having made chemical reaction velocity is led in the interior energy movement velocity of molecule and the fierce raising of reaction temperature.Simultaneously traditional heating means realize that by heat conduction and thermal convection current therefore, firing rate is slow, and the heating of microwave advantage is fast, and the system temperature that is heated is even, and molecular dipole is apart from big more, then heating is fast more, just can improve the hydrolysis speed of polyester fiber this moment significantly.Traditional dacron alkali decrement needs about 1 hour, only needs 1-3 minute and adopt microwave that dacron is carried out the alkali decrement.
The present invention can adopt following technical scheme: (contrast Figure of description)
1. contrast the different reduction rate of various dacrons, the preparation naoh concentration is put into groove.(seeing Figure of description A)
2. dacron is by padding machine selvage guide rod, and tension roller enters the microwave cavity device.(seeing Figure of description B) carries out the alkali decrement.
3. dacron enters the open width rinsing machine rinsing bowl after the reaction of microwave decrement.(seeing Figure of description C)
4. washing → neutralization → washing.
The present invention adopts microwave as follows to the advantage that dacron carries out the alkali decrement:
It is embodiments of the invention below: fabric: terylene filament yarn fabric S9055 terylene crape technology preparation: caustic soda (24.5% (31 ° of Bc)) tankful
Bleeding agent 1g/l process conditions: pick-up rate 50%, speed of a motor vehicle 40m/min
Microwave 3 minutes
Wash 60 ℃ of two lattice
In and 40 ℃ of two lattice
Cold water three lattice
Cold water goes out cloth
