preparation example Construction

[0060] The preparation method of serous film of the present invention comprises the steps:

[0061] Slurry preparation-slurry spreading-slurry cooking-slurry drying into film-filming.

[0062] Since the thickness of the size film determines the mechanical properties of the size film, such as breaking strength, elongation at break, wear resistance and solubility, the thickness of the prepared size film is generally 0.2-0.5mm. Therefore, when preparing the size film, it is necessary to control the amount of the size liquid or the thickness of the size tank to obtain the required thickness of the size film.

[0063] When using a slurry laying table with a slurry tank to spread slurry, fill the slurry tank with slurry, and the scraping surface of the squeegee moves against the upper surface of the slurry laying table to scrape excess slurry into the slurry overflow tank, here , the depth of the selected size tank should be compatible with the thickness of the prepared size film, ...

Embodiment 1

[0100] The method of the present invention is described in detail by taking the preparation of pure cotton serous film as an example. Use a flat laying table.

[0101] Preparation of slurry: prepare slurry for the components of 60% starch, 30% PVA, and 10% polymethylacrylate by weight percentage, and mix the slurry with water to form a slurry with a solid content of 8% for subsequent use;

[0102] Slurry spread: Calculate the amount of slurry according to formula (2), spread the slurry on the slurry laying table, and scrape the slurry with a scraper;

[0103] Vaporization of slurry water: cover the cover of the slurry laying table, heat the slurry to 130°C with a heating device, and heat at a constant temperature until the slurry is dried and formed into a film, and control the humidity in the cover of the slurry laying table to 65-72%;

[0104] To form a film, cool the size film at room temperature, and open the laying table to cover the film after reaching room temperature. ...

Abstract

Aiming to overcome the problems in the prior art that the structure of the device for preparing spinning size films is simple to only dry under a natural state, the time of preparing size films is hard control effectively, the size is liable to deterioration, and the prepared size films are liable to crack due to the existence of internal stress, the invention provides a spinning size film preparation method and a spinning size film preparation device. The preparation device comprises a size spreading platform and a levelness adjustment device for adjusting the levelness of the size spreading platform, wherein the preparation device further comprises a temperature controller for controlling the temperature and heating time of the size spreading platform, a size film humidity control device and a size scraping device for scraping the spread size. Through the adoption of the structure, the device for preparing spinning size films and the preparation method of spinning size films can control the size film forming time and form size films under a constant-temperature and constant-humidity state.

Description

technical field [0001] The invention relates to an instrument for preparing textile size film and a preparation method of textile size film. Background technique [0002] The adhesion performance of the size to the sizing fiber and the size film performance after the size film is formed reflect the sizing performance of the size and determine the weaving ability of the sizing yarn. Correctly evaluate the size film performance of the size, optimize the size formula, and improve the quality of the sizing yarn Is of great significance. [0003] When judging the advantages and disadvantages of a certain slurry, the size film is often made in the laboratory to test the performance of the size film. The existing preparation method of the size film comprises the steps of laying the size solution on the tempered glass plate platform, spreading the size solution with a glass rod, and placing it at room temperature to dry naturally. The size film is prepared by the above method, the...
