Problems solved by technology

[0003] In the current mercerizing process of cotton and cotton blended fabrics, a cloth clip mercerizing machine or a straight roller mercerizing machine is used for mercerizing, which requires a large amount of steam. After mercerizing, a separate desizing treatment is required. The process is long, the steam consumption is large, and the energy consumption is high. high
And due to the use of a large amount of high-concentration caustic soda, even if the alkali recovery technology has been adopted, it still poses a burden to the treatment of printing and dyeing wastewater to a certain extent

Abstract

The invention provides a grey cloth cold batch mercerizing process method for cotton and cotton blended fabric, which belongs to a dyeing and finishing pretreatment process for cotton and cotton blended fabric. The process method comprises processes of singeing, alkali padding, rolling, reverse rolling and heaping, washing, oxygen bleaching, weft finishing and tentering; in the alkali padding process, alkali liquor is padded by using a padding liquor roller, the NaOH content of the alkali liquor in an alkali liquor tank is 160 to 180 grams per liter, the balance is water, and the alkali liquor in the alkali liquor tank is circulated by using a circulating pump; in the washing process, counter current washing is performed in a de-sizing machine by using 90 to 95 DEG C hot water, the speed is 48 to 52 meters per minute, and the cloth falls with tide; and in the oxygen bleaching process, the speed is 45 minutes per minute, the temperature in a track-type steam box is between 96 and 99 DEG C, and the heaping is performed for 45 minutes. The mercerizing process method combines the mercerizing process and the de-sizing process into a one-step process so as to shorten the process flow, reduce the steam consumption, relatively reduce the consumed caustic soda quantity and save the wastewater treatment expense.

Description

technical field [0001] The invention relates to a process method for mercerizing gray fabrics of cotton and cotton blended fabrics, and belongs to a pre-treatment process for dyeing and finishing of cotton and cotton blended fabrics. Background technique [0002] Cotton products (yarns, fabrics) are treated with concentrated caustic soda solution by padding and rinsing under tension, and then the caustic soda is washed away under tension, which is called "mercerizing" process. After the cotton fiber is soaked with concentrated caustic soda solution, irreversible and severe swelling of the cotton fiber can be observed, the cross section of the fiber changes from a flat kidney shape to a round shape, the cell cavity also shrinks, the longitudinal natural twist disappears, and the length shortens. If the alkali is soaked when tension is applied to the fiber, the fiber will not shrink. At this time, the surface wrinkles of the fiber will disappear and become a very smooth cylind...
