[0004] The open magazine "Shanghai Textile Science and Technology Trends", published in 1977, No. 3, titled "Liquid Ammonia Mercerizing of Fabrics That Don't Pollution the Environment", mentioned the liquid ammonia finishing of cotton fabrics, although it uses liquid ammonia to mercerize cotton fabrics The method can indeed have a good treatment effect and the effect of recycling, but its disadvantage is that the liquid ammonia mercerizing equipment is very expensive, the recycling cost is high, and the energy consumption is also large
[0005] The open magazine "Journal of Beijing Institute of Chemical Fiber Engineering", the date of publication, No. 2, 1986, titled "Research on Liquid Ammonia Treatment Combined with Foam Resin Finishing", mentioned the method of mercerizing cotton fabrics with liquid ammonia combined with foam resin, although it uses The method of this method has indeed played a role in improving the washability of the fabric and improving the strength and elasticity of the fabric, but its disadvantage is that the process is complicated, and foam resin finishing is required after the liquid ammonia treatment, and the cost is relatively high
Although it uses non-alkali mercerizing agent DGF to mercerize multi-component fiber knitted fabrics, it does improve the fabric mercerizing effect and reduce the effect of alkali agents, but its disadvantage is that the finishing agent is relatively expensive and the process cost Higher, more water consumption in the finishing process
Although it uses non-alkali mercerizing agent DGF to treat knitted fabrics for mercerization, it does improve gloss and softness, but its disadvantage is that the trial range of this method is narrow

Embodiment 1

[0030] According to the above process steps: select 1g of pure cotton fabric as the fabric to be mercerized. Sodium hydroxide is placed in the mixed solution of ethanol and water, and after stirring evenly, it is prepared into lye, wherein, the bath ratio of lye is 1:50, the volume ratio of ethanol and water is 95%:5%, and sodium hydroxide The concentration is 280g / L. Under the action of the tension applied by the mercerizing machine to the pure cotton fabric, the pure cotton fabric is placed in lye for treatment, the treatment temperature is 25° C., and the treatment time is 30 seconds. Mix ethanol and water uniformly to prepare washing liquid, wherein the bath ratio of washing liquid is 1:50, and the volume ratio of ethanol and water is 95%:5%. The pure cotton fabric treated with the alkali solution is washed in a washing solution until the pH of the pure cotton fabric after washing is 7. The pure cotton fabric after washing is dried, and drying temperature is 80 ℃.

Abstract

The invention relates to a mercerizing method of cotton fabric and belongs to textile printing and dyeing pretreatment process technology. According to the mercerizing method of the cotton fabric provided by the invention, the proportioning of an alkali solution and a cleaning solution in the cotton fabric mercerizing process is changed, the cotton fabric is mercerized by using the alkali solution which is prepared by mixing an alcohol organic solvent in high proportion, a little water, and sodium hydroxide, and the mercerized cotton fabric is washed by using the washing solution which is prepared by mixing the alcohol organic solvent and a little water. Not only is water consumption in the mercerizing process greatly reduced, but also the mercerizing effect of the cotton fabric can be improved; the cotton fabric treated by using the method provided by the invention is not only good in luster and dyeing performance, but also excellent in hand feeling softness, size stability and wrinkle resistance; by adopting the method provided by the invention, the problems of high water consumption and heavy pollution in a traditional mercerizing process are solved; the alcohol organic solvent used by the method provided by the invention is safe, nontoxic, and easy in recycling; and the mercerizing method is economical, energy-saving, safe and environment-friendly.

Description

technical field [0001] The invention relates to a cotton-type fabric mercerizing method, which belongs to the pre-treatment technology of textile printing and dyeing. Background technique [0002] The conventional mercerizing process is to treat cotton-type fabrics with concentrated sodium hydroxide solution under tension to obtain good gloss, dimensional stability and dyeing performance. Generally, water is used as a solvent for sodium hydroxide, which leads to an increase in water consumption during the mercerizing process. In addition, a large amount of water resources are also required to wash the fabric after mercerizing. Therefore, the use of a large amount of water causes the waste water after mercerizing to become a big problem. [0003] With the continuous improvement of science and technology, in recent years, many scientific researchers have begun to study anhydrous or less water mercerizing. [0004] The open magazine "Shanghai Textile Science and Technology Tr...
