Problems solved by technology

[0004] The currently used sealed liquid ammonia mercerizing machine can effectively carry out liquid ammonia mercerizing on woven fabrics, but it cannot produce knitted fabrics. This is because woven fabrics themselves are relatively compact and flat, while knitted fabrics are relatively elastic and have selvedges. The natural tendency

Abstract

The invention discloses a liquid ammonia mercerizer equipment of knitting fabric. The equipment comprises a woven fabric entering device, a liquid ammonia mercerization device and a liquid ammonia recovery device and is characterized in that a first group of cloth guide rollers is arranged above the woven fabric entering device, a group of scroll roller combination is arranged between the woven fabric entering device and the liquid ammonia mercerization device in which five groups of scroll roller combinations are arranged, and a group of scroll roller combination is arranged between the liquid ammonia mercerization device and the liquid ammonia recovery device. The equipment has the advantages of reducing the tension in the delivery process of the knitting fabric, simultaneously poking the turned edge of the knitting fabric aside to prevent edge curl and reducing the wrap-direction shrink. Besides, avoiding an original preliminary drying cylinder in the delivering process, the knitting fabric directly enters the liquid ammonia mercerization device through the first group of cloth guide rollers and is consequently prevented from being extruded and forming folds. Therefore, on the same improved liquid ammonia mercerizer, tatting fabric and knitting fabric can be smoothly mercerized as long as different fabric delivering routes are selected.

Description

technical field [0001] The invention relates to a processing equipment for clothing fabrics, in particular to a liquid ammonia mercerizing machine equipment for knitted fabrics. Background technique [0002] Cotton fibers can undergo irreversible swelling in concentrated caustic soda solution and under the action of tension, that is, mercerizing. There are disadvantages of low recovery rate of spent alkali, high environmental pollution, and relatively hard fabric after mercerizing; later scientific research found that using liquid ammonia small molecules to enter the interior of cotton fibers can also cause irreversible swelling of cotton fibers, that is, liquid ammonia mercerizing. The effect is equivalent to conventional caustic soda mercerizing, and the fabric after liquid ammonia mercerizing becomes softer and softer in luster. At the same time, the non-ironing performance of the fabric after liquid ammonia mercerizing is improved. [0003] Liquid ammonia mercerizing is...
