An integrated device for warp foam wetting and foam sizing

Abstract

The invention discloses a warp foam-moisturizing and foam-dressing integrated device. The warp foam-moisturizing and foam-dressing integrated device comprises a warp moisturizing unit, a foam-dressing unit and yarn guide rollers. The warp moisturizing unit comprises moisturizing rollers used for moisturizing warps by foam and a foam applicator above the moisturizing rollers. The foam applicator comprises a moisture supplier, a foam generator and a sprayer, wherein the moisture supplier contains water and blowing promoter. The foam-dressing unit comprises dressing rollers and another foam applicator, wherein the dressing rollers perform foam dressing. A size supplier is communicated with the foam generator generating foam of the size, the foam generator is communicated with a conveying pipeline of the sprayer, and the dressing rollers are arranged below the sprayer. The moisturizing rollers and the dressing rollers include at least one pair of rollers tangential horizontally, and yarns are gripped by the moisturizing rollers and the dressing rollers respectively and are guided out through the yarn guide rollers and into the foam-dressing device through the warp moisturizing device. The blowing promoter comprises foaming agent, stabilizer and preservative. The blowing promoter in the moisture supplier is same as that in the size supplier.

Description

technical field [0001] The invention relates to an integrated device for warp yarn foam sizing, in particular to an integrated device for warp yarn foam wetting and foam sizing, and belongs to the technical field of warp yarn 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 t...

AI Technical Summary

Problems solved by technology

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
