A method of warp foam wetting and foam sizing and its special equipment

Abstract

The invention discloses a foam wetting method and a foam starching method for a warp and special equipment thereof. The method comprises the following steps: 1) conveying water and foaming promoter in a certain proportion to a foaming machine by a wetting supplier, and conveying wetting foam which is foamed by the foaming machine to a sprayer through a pipe; 2) passing the warp through two tangent wetting rollers, spraying the wetting foam from top to bottom by the sprayer, and spraying the wetting foam to the surface of the warp; 3) guiding the wet warp out by a warp guiding roller, and passing the warp guided out through two tangent starching rollers; 4) conveying size and foaming promoter in a certain proportion to the foaming machine by a size supplier, and conveying the wetting foam which is foamed by the foaming machine to the sprayer through the pipe; 5) placing the sprayer above the starching roller, spraying the starching foam from top to bottom by the sprayer, and spraying the starching foam to the surface of the warp; and 6) pulling the warp which is subjected to foam starching to the next procedure by a dynamic mechanism.

Description

technical field [0001] The invention relates to a warp foam sizing method and special equipment thereof, and belongs to the technical field of warp sizing. Background technique [0002] Warp yarns need to be pre-wetted before foam sizing. The so-called warp yarn pre-wetting is to completely immerse the warp yarn in a high-temperature water tank at about 90°C, and go through processes such as dipping, pressing, and washing to remove dust, linters, cotton wax, and pectin attached to the surface of the yarn, which affect the wetting of the warp yarn. At the same time, it is washed with hot water to reduce the surface tension of the yarn, thereby improving the adsorption conditions of the warp yarn, so that the slurry can be evenly soaked and covered, and then the excess water is rolled off under the action of high pressure to make the slurry more firm. Adhere to the warp yarn at the same place, and then form a complete size film after drying. After pre-wetting the yarn, the ad...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned traditional foam sizing has the following problems: after the warp yarns are pre-wetted, there are sewage treatment and discharge problems, and the water content of the warp yarns increases greatly, so it needs to be dried. The research on saving energy consumption in sizing shows that in the whole sizing process, the energy consumption of drying Dryness is the main part; there is a problem of uneven foaming in the foaming device, which affects the sizing efficiency and causes waste of cost
