Problems solved by technology

Textile mills generally adopt the method of mixing multiple sizing materials when sizing. The sizing procedure is complicated, which brings difficulties to the operation. There are also fluctuations in the quality of the sizing liquid caused by human factors, which is not conducive to the stability of the sizing quality.
The chemical slurry in the formulation is expensive, resulting in increased production costs

Embodiment 1

[0037] Put the potato flour in a drying oven at 80 °C for 24 h, and place the dried starch in an insulated container. The thickness of the starch layer is about 20 mm. Put the container into the processor, and use a vacuum pump to extract the processor so that the pressure in the processor is about 5 Pa. Introduce non-polymerizable gases He and O 2 (the molar ratio is 6:1), until the pressure inside the processor is 25 Pa; turn on the switch to preheat, and apply voltage to the electrodes placed in the processor to modify the starch. Adjust the discharge frequency of the applied voltage to 38.0 MHz, the discharge power to 800 W, the gas flow rate to 750 mL / min, and the processing time to 90 s. Turn off the switch, slowly release the pressure to normal pressure, and take out the starch, which is non-equilibrium plasma modified starch.

[0038] Configuration of combined size of modified starch. Put 45 parts of the above-mentioned non-equilibrium plasma modified starch (by wei...

Embodiment 2

[0040] Waxy cornmeal was dried in a drying oven at 70 °C for 24 h, and the dried starch was placed in an insulated container with a starch layer thickness of about 20 mm. Put the container into the processor, and use a vacuum pump to extract the processor so that the pressure in the processor is approximately equal to 4 Pa. Introduce non-polymerizable gas He and air (molar ratio is 3:1) until the pressure inside the processor is 30 Pa; turn on the switch to preheat, and apply voltage to the electrodes placed in the processor to modify starch. Adjust the applied voltage discharge frequency to 38.0 MHz, the discharge power to 800 W, the gas flow rate to 900 mL / min, and the processing time to 120 s. Turn off the switch, slowly release the pressure to normal pressure, and take out the starch, which is non-equilibrium plasma modified starch.

Embodiment 3

[0043] Put the cassava flour in a drying oven at 80 °C for 24 h, and place the dried starch in a treatment insulated container with a starch layer thickness of about 15 mm. Put the container into the processor, and use a vacuum pump to extract the processor so that the pressure in the processor is approximately equal to 4 Pa. Introduce non-polymerizable gases He and O 2 (the molar ratio is 8:1), until the pressure inside the processor is 30 Pa; turn on the switch to preheat, and apply voltage to the electrodes placed in the processor to modify the starch. Adjust the discharge frequency of the applied voltage to 38.0 MHz, the discharge power to 700 W, the gas flow rate to 600 mL / min, and the processing time to 120 s. Turn off the switch, slowly release the pressure to normal pressure, and take out the starch, which is non-equilibrium plasma modified starch.

Abstract

The invention discloses a producing method of an environment-friendly composite sizing agent. The producing method includes: placing particle starch after being dried into a cabinet type unbalance plasma processor, feeding non-polymeric gas, and adjusting internal pressure of the processor; opening a switch for preheating, applying voltage to an electrode placed in the processor, and modifying the starch in situ; and combining obtained modified starch with converted starch to obtain the composite sizing agent which is use for sizing of heavy weight denim yarns. The producing method is low in energy consumption and short in processing time by using unbalance plasma technology to modify the starch in situ. No chemical sizing agent is contained in the modified starch composite sizing agent formula, and therefore the size mixing process is time-saving, and simple and convenient, and yarn sizing cost is low. In addition, the sizing agent can be degraded completely after being abandoned, and causes no damage on environment.

Description

technical field [0001] The invention relates to a production method of slurry in the textile field, in particular to a production method of environment-friendly combined slurry. Background technique [0002] Denim is a pure cotton thick-gauge high-density fabric, and the cloth surface is required to be flat and have clear lines. In order to achieve this effect, high tension and strong weft beating technology must be used when weaving, and weaving is usually done on a rapier loom with fast speed and high tension. . At the same time, most denim is pre-dyed by warp yarn before weaving, and this process will cause considerable damage to the yarn. Warp sizing used in denim weaving is one of the key processes in denim production. Through sizing, the warp surface is covered with a layer of smooth, wear-resistant, flexible and certain-strength size film, and at the same time, part of the size is penetrated into the inside of the yarn to increase the adhesion between fibers and imp...
