Problems solved by technology

[0003] However, after sizing with the slurry formed by the current cooking process, sometimes fine particles are attached to the textile fibers, but the particle diameter of these particles may be larger than the gap between the reed blades on the loom, resulting in wrapped polymer particles. Vinyl alcohol (PVA) textile fibers cannot pass through the gaps of the reed blades normally
In this way, during the high-speed beating-up process of the loom, the traction and repeated friction of the particles by the reed will break the size film wrapped on the surface of the fiber, resulting in the bare fiber, which will affect the weaving efficiency and reduce the quality of the product. Weaving difficulty of the process

Embodiment Construction

[0020] The present invention discloses a process for boiling polyvinyl alcohol, which comprises: after heating water to 88-92°C, adding solid polyvinyl alcohol into the water at a feeding rate of 11.11 g / s, and stirring, After the solid polyvinyl alcohol is completely dissolved, a polyvinyl alcohol slurry is formed.

[0021] Preferably, the water is heated to 90°C.

[0022] Preferably, the stirring step is synchronized with the step of adding solid polyvinyl alcohol.

[0023] As a further improvement of the present invention, the duration of the input of solid polyvinyl alcohol is 30 minutes.

[0024] The present invention also discloses a textile fiber sizing process using the above-mentioned cooking process, which includes: heating the water to 88-92°C, and throwing solid polyethylene into the water at a feeding rate of 11.11g / s After the solid polyvinyl alcohol is completely dissolved, a polyvinyl alcohol slurry is formed, and the spinning fiber is fully immersed in the formed pol...

Abstract

The invention discloses a polyvinyl alcohol size boiling technology and a textile fiber sizing technology. The polyvinyl alcohol size boiling technology includes the steps that water is heated to 88 DEG C to 92 DEG C, solid polyvinyl alcohol is added into the water at the charging speed of 11.11g / s and is stirred, a polyvinyl alcohol sizing agent is formed after the solid polyvinyl alcohol is completely dissolved. The sizing agent formed through the polyvinyl alcohol size boiling technology does not contain tiny particles, and after textile fibers are covered the sizing agent, particles hindering spinning can not form on the textile fibers, so that abrasion resistance of the textile fibers keeps stable, quality of textile products is improved, and production efficiency of weaving is improved.

Description

Technical field [0001] The present invention relates to the technical field of textiles, in particular to a cooking process of polyvinyl alcohol and a textile fiber sizing process for the cooking process of polyvinyl alcohol. Background technique [0002] In order to ensure that the textile fiber is not affected by friction during the high-speed air-jet loom weaving process, the original state of the textile fiber needs to be sizing and wrapped. According to the particularity of different spinning fibers, different spinning fibers have different sizes when sizing. Requirements. For multi-fiber raw materials, polyvinyl alcohol (PVA) should be selected, and polyvinyl alcohol (PVA) is solid at room temperature. The conversion of solid polyvinyl alcohol (PVA) into liquid slurry is called the cooking process. Using liquid polyvinyl alcohol (PVA) to wrap the spinning fiber is to sizing the spinning fiber. The spinning fiber wrapped with polyvinyl alcohol (PVA) has better abrasion resi...
