The method comprises the following step of: accurately weighting ingredients according to a size mixing formula and solid containing rate requirements; the method is characterized in that a container containing a supersonic generator is added with a certain amount of water, then the ingredients are gradually poured in water, and finally water is added to reach the required mass according to the size mixing formula; and the agglomeration of ingredients in the water is dissolved after full mixing, and the supersonic generator is opened so as to carry out concussion on size in the container till the temperature of size achieves 70-75 DEG C, thereby finishing size mixing. The method is suitable for the size of which the solid containing rate is no more than 8%, the size quality after the size mixing is stable, the aliquation is difficult, the viscosity of the size is obviously reduced and the viscosity can be guaranteed to keep steady for a long time under the same solid containing rate condition, thereby being beneficial to leading the size to infiltrate the interior of yarns and keeping the stability of sizing quality; and maximum temperature in a size mixing process is not higher than 75 DEG C, the gelatinization time is about 30 minutes, the process temperature is reduced, the time is shortened, and the method can save energy and reduce consumption.
Description
Technical field
The present invention relates to a kind of method of utilizing ultrasonic wave to size mixing, belong to the textile chemistry technical field
Background technology
Sizing mixing is weaving manufacturing procedure important link, and the quality of slurries quality will directly determine and influence loom efficiency and fabric quality.Traditional size mixing technology requires the whole process of sizing mixing under 95 ℃ hot conditions, to continue more than 2 hours, and energy consumption is very big.Sizing technique subsequently has very high requirement to the viscosity of slurries again, and the slurries that viscosity is low can increase permeability, improves cohesive force between fiber, for warp sizing technology provides advantage.
Summary of the invention
The purpose of this invention is to provide size mixing energy consumption and make the mixing method that the viscosity of slurries reduces of a kind of reduction.
In order to achieve the above object, technical scheme of the present invention has provided a kind of method of utilizing ultrasonic wave to size mixing, and step is:
Step 1, basis are sized mixing prescription according to the correct weigh batching of solid content requirement, it is characterized in that:
Step 2, elder generation add the water and the batching of the required quality of prescription of sizing mixing in the container of supersonic generator is housed;
Step 3, the abundant caking that in water, is become until batching that stirs leave;
Step 4, unlatching supersonic generator reach 70-75 ℃ to the temperature that the slurry in the container shakes until slurries, and completion is sized mixing, and wherein, the ultrasonic frequency scope of supersonic generator is 25kHz-40kHz.
Preferably, the time of concussion is 1 hour described in the step 4.
Preferably, the power of said supersonic generator is 100W.
Ultrasonic wave is a kind of elastic mechanical ripple, propagates in elastic fluids such as gas, liquid, solid with the mode of compressional wave usually, and be a kind of mode of propagation of energy.Penetration of ultrasound waves is very competent, and high-intensity ultrasonic wave can produce mechanical effect, fuel factor, biological effect etc.When in liquid medium, propagating, ultrasonic wave can produce strong impact and cavitation phenomenon on the interface, so ultrasonic wave often is used to all trades and professions as a kind of important manufacturing process.At field of textiles, ultrasonic wave has been used for wet processing technologys such as destarch, kiering, bleaching, washing.
The present invention uses cavitation effect of ultrasonic waves to replace the machinery concussion, and cavitation effect of ultrasonic waves can make liquid internal produce immense pressure, thereby the big molecule of slurry is interrupted, and cavitation increases with ultrasonic wave effect frequency and reduces.
This method is applicable to the slurries of solid content≤8%; The slurries steady quality of its modulation; Be difficult for aliquation, significantly reduce slurry viscosity under the identical solid content condition and can guarantee that viscosity keeps stable in than the long time, be beneficial to slurries and infiltrate yarn inside, keep sizing quality stable.Maximum temperature is not more than 75 ℃ in the process of sizing mixing, and gelatinization time can reduce technological temperature about 30min, and is the shortening time, energy-saving and cost-reducing.
The specific embodiment
For making the present invention more obviously understandable, elaborate as follows with a preferred embodiment now.
Step 1, basis are sized mixing prescription according to the correct weigh batching of solid content requirement; Getting oxidized starch (regain 14%) 27.9g, PVA1799 (regain 5%) 3.16g, acrylic acid 2.1g and wax disk(-sc) 0.9g in the present embodiment and form slurry, is that 6% solid content slurries are subsequent use after weighing is good.
Step 2, earlier in the container of supersonic generator that power is 100W is housed, add a certain amount of water, will prepare burden and slowly pour in the water, the last prescription according to sizing mixing adds entry again until required quality;
Step 3, the abundant caking that in water, is become until batching that stirs leave, and mixing time is generally about 10 minutes;
Step 4, open supersonic generator, the ultrasonic frequency of supersonic generator is set at 25KHz, the slurries in the container were shaken 1 hour, reach 70-75 ℃ until the temperature of slurry, completion is sized mixing.
The slurries steady quality that this method is sized mixing is difficult for layering; Significantly reduce slurry viscosity under the identical solid content condition and can guarantee that viscosity keeps stable in the long time, the slurry viscosity fluctuating range is no more than 1cp; Being beneficial to slurries infiltrates yarn inside and keeps the stable of sizing quality; Maximum temperature is not more than 75 ℃ in the process of sizing mixing, and gelatinization occurs in about 30min, can reduce technological temperature, and is the shortening time, energy-saving and cost-reducing.
