Description
Technical Field
The invention belongs to the technical field of fabric finishing methods, and particularly relates to a high non-iron cotton regenerated cellulose fabric finishing method based on liquid ammonia treatment.
Background
The main component of regenerated cellulose fiber is cellulose, and its molecular structural formula is identical to that of cotton, so that it has many characteristics similar to that of cotton, and possesses good hygroscopicity, air permeability and comfortableness. In recent years, as the price of cotton continuously rises, the production process of regenerated cellulose fiber continuously stabilizes, and the regenerated cellulose is widely applied, and is the third largest fiber after terylene and cotton. The regenerated cellulose fabric is environment-friendly in raw materials and comfortable to wear, is favored by consumers, but has the problems of poor dimensional stability, low strength, easiness in wrinkling, capability of improving the dimensional stability, flatness, strength, hand feeling and the like of the fabric through liquid ammonia finishing in the dyeing and finishing process.
The regenerated cellulose processing flow is generally as follows: the preparation of the porridge, the spinning forming, the post-treatment, the packaging and shipment, wherein the post-treatment before packaging is oiling, drying, the oiling can reduce the friction coefficient of the fiber, reduce the electrostatic effect, improve the hand feeling of the fiber, improve the spinnability of the fiber, and the fiber strand after oiling can be packaged and shipped after drying. In general, the main component of grease used for oiling is dimethyl silicone oil, in the process of contacting with liquid ammonia, the liquid ammonia can dissolve the dimethyl silicone oil on the surface of the fiber, after the liquid ammonia is gasified and volatilized, the dissolved silicone oil is gathered on the surface of the fiber to form irregular oil spots or oil marks, and the problem restricts the improvement of the quality of cotton regenerated cellulose fabric, wherein the quality of the fabric is high easy-care, better in hand feeling and the like.
Publication number CN108611847a proposes a fabric with high non-ironing property, high whiteness and high color fastness and its processing method, the processing flow is: preparing a fabric, singeing, desizing and scouring, special bleaching, mercerizing, liquid ammonia, whitening and washing, pre-softening, preshrinking, moisture crosslinking and washing, re-bleaching, tentering and color-mixing, and checking and packaging; the special bleaching process comprises the following steps: naClO 2、CH3 COOH, steam box temperature 90 ℃, stacking time 30min; bleaching process: penetrant, chelating agent, stabilizer, H 2O2, naOH, stacking time: 15-16min. The whiteness and the hand feeling of the processed fabric are improved, but the process is a common process of processing with high non-ironing property and high whiteness, the whitening performance is mainly improved by bleaching and whitening modes, the oil outlet problem existing in the liquid ammonia process cannot be solved, and the hand feeling is still to be improved.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects in the prior art, and the finishing method of the high non-ironing cotton regenerated cellulose fabric based on liquid ammonia treatment is provided, so that the finished fabric has no oil printing stain in appearance, flatness of more than 3.5 grade, soft and smooth hand feeling and improved overall quality of the cotton regenerated cellulose fabric.
