Embodiment 1

[0017] A method for ultrasonically assisted textile size preparation, comprising the following steps: (1) forming a plurality of ultrasonic vibrators into an array and placing them outside the bottom of a size mixing kettle; (2) using conventional variable starch as the main size for size mixing, starch The raw pulp concentration is 6% to 10%, preferably the starch raw pulp concentration is 8%; add water, modified starch, soaking agent and softener into the pulping kettle, start stirring and heat up; (3) The temperature in the pulping kettle Start the ultrasonic generator when the temperature rises to 50°C, so that multiple ultrasonic vibrators can generate ultrasonic vibrations with a frequency of 30kHz and a power density ranging from 30W / L to 50W / L, and perform ultrasonic effects on the mixed liquid in the slurry mixing tank; (4) to be adjusted After the temperature in the slurry tank was raised to 80°C, it was kept warm for 30 minutes, and at the same time, the ultrasonic w...

Embodiment 2

[0019] A method for ultrasonically assisted textile size preparation, comprising the following steps: (1) forming a plurality of ultrasonic vibrators into an array and placing them outside the bottom of a size mixing kettle; The raw pulp concentration is 8% to 12%, preferably the starch raw pulp concentration is 10%; add water, esterified starch, soaking agent and softener into the pulping kettle, start stirring and heat up; (3) in the pulping kettle Start the ultrasonic generator when the temperature rises to 50°C, so that multiple ultrasonic vibrators generate ultrasonic vibrations with a frequency of 25kHz and a power density ranging from 30W / L to 50W / L, and perform ultrasonic effects on the mixed liquid in the slurry mixing tank; (4) Waiting After the temperature in the slurry mixing kettle rises to 80°C, it is kept for 45 minutes, and at the same time, the ultrasonic wave is continued to obtain the required slurry.

Embodiment 3

[0021] A method for ultrasonically assisted textile slurry preparation, comprising the following steps: (1) forming a plurality of ultrasonic vibrators into an array and placing them outside the bottom of a slurry mixing kettle; (2) using esterified starch and polyvinyl alcohol (PVA) as the main slurry Mix the raw materials, add water, esterified starch, PVA, penetrating agent and softener to the slurry mixing kettle, start stirring and heat up; (3) When the temperature in the slurry mixing kettle rises to 50°C, start the ultrasonic generator to make the complex An ultrasonic vibrator generates ultrasonic vibration with a frequency of 30kHz and a power density ranging from 30W / L to 50W / L, and performs ultrasonic action on the mixed liquid in the slurry mixing tank; (4) After the temperature in the slurry mixing tank rises to 80°C, keep it warm for 40 minutes , and at the same time continue the ultrasonic action to obtain the required slurry.

Abstract

The invention discloses a method for ultrasonic-assisted preparation of textile size and relates to the field of textile. The method comprises the following steps of: (1) arranging a plurality of ultrasonic vibrators into an array and placing the array at the outer side of the bottom part of a size mixing kettle; (2) putting a sizing agent, an additive and water into the size mixing kettle, starting stirring and raising the temperature; (3) when the temperature in the size mixing kettle is raised to 50 DEG C, starting an ultrasonic generator and leading the plurality of ultrasonic vibrators to generate ultrasonic vibration with the frequency ranging from 25KHZ to 40KHZ and the power density ranging from 30W / L to 50W / L; and (4) after the temperature in the size mixing kettle is raised to 80 DEG C, maintaining the temperature for a period of time, and simultaneously continuing the ultrasonic action. The method disclosed by the invention has the beneficial effects that the size mixing temperature can be obviously reduced, and the time of a size mixing process can be shortened; by utilization of an ultrasonic cavitation effect, the viscosity of the size can be obviously reduced, and the concentration of the size can be increased on the premise of lower viscosity of the size; and after ultrasonic action, the adhesion property of textile fiber can be improved by the size.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing ultrasonic-assisted textile slurry. Background technique [0002] In the past ten years, my country's research on the application of ultrasonic technology has been very active. Ultrasonic technology is completed through the physical process of ultrasonic generation, transmission and reception, and is a general-purpose technology based on physics, electronics, mechanics and materials science. Ultrasonic waves form mechanical vibrations of medium particles in elastic media (such as liquids), which can cause interactions with elastic media. The effect in the liquid phase mainly comes from the cavitation of ultrasonic waves. The thermal action generated by the collapse of cavitation bubbles can make the medium absorb ultrasonic energy and transform it into heat energy, increasing its own temperature; and the collapse of cavitation bubbles produces strong mechanical eff...
