A kind of environment-friendly textile size and preparation method thereof

Abstract

The invention relates to eco-friendly textile pulp and a preparation method thereof. The eco-friendly textile pulp comprises main materials and assistants. The main materials comprise nano-silica-modified starch, starch acetate, chloroepoxyethane crosslinked starch, methacrylic acid, butyl methacrylate, acrylamide, sodium sulfamate, diphenylmethane and protein amino acids. The assistants comprise methanol, 2-naphthol, monochloroacetic acid and NaOH. The preparation method of the textile pulp comprises (1) preparing the main materials, (2) uniformly mixing the main materials and the assistants to obtain the eco-friendly textile pulp. In sizing, the eco-friendly textile pulp is applied to a textile at a temperature range of 25-28 DEG C, and the yarn coated with the eco-friendly textile pulp has stable performances, high strength and high abrasion resistance and is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of textile sizing, in particular to an environment-friendly textile size and a preparation method thereof. Background technique [0002] There are four main types of size widely used for textile sizing: modified starch, polyvinyl alcohol, polyester and polymethacrylate size. Modified starch sizing has good film-forming properties, strong affinity with natural fibers, and is easy to desizing. It is the main sizing component of textile sizing; not enough. Polyvinyl alcohol size film has high strength, good flexibility, and good slurry fluidity; however, polyvinyl alcohol is difficult to desizing, and because polyvinyl alcohol is difficult to degrade, it is easy to cause white environmental pollution, and the European Union has banned its use by legislation. The chemical structure of polyester size is similar to that of polyester, so it has strong affinity with polyester fiber, especially suitable for polyest...

AI Technical Summary

Problems solved by technology

The solid content of polymethacrylic acid emulsion is only 25%, and the transportation cost is high; and the presence of emulsifiers often deteriorates its performance, such as generating foam and affecting its compatibility with other types of slurries, etc.

Solid methacrylate sizing is more popular, but the solid methacrylate sizing on the market has serious moisture absorption and stickiness, and the strength of the size film is not enough

Therefore, neither polymethacrylic acid emulsion nor solid methacrylate can completely replace polyvinyl alcohol.

[0003] Using the existing size sizing method, the existing size must be above 90°C when sizing, to prevent the viscosity increase after the temperature drops from affecting the sizing quality, and also prevent many sizing defects such as sizing skin and sizing spots, so it is necessary Maintaining such a high temperature all the time will waste a lot of steam, and the continuous high temperature cannot achieve energy-saving production. During sizing, because there is always steam heating and heat preservation in the size tank of the sizing machine, the condensed water in the steam will be brought into the The sizing tank reduces the solid content of the sizing solution and causes changes in the sizing amount of the sizing yarn. Especially in the cold winter, the condensed water in the steam pipe is easy to generate and is very unstable. This is also the case in many factories, which is also the sizing The key to the problem of underweight sizing unknowingly during the process
