Abstract
The invention relates to the technical field of argon bleaching and dyeing technology in the textile industry, and in particular relates to an argon bleaching and dyeing technology of the acrylic yarn. The argon bleaching and dyeing technology of the acrylic yarn comprises the following steps: (1) placing the acrylic yarn into water, and then sequentially adding auxiliaries which are respectively 1g of chelating disperse agent per liter of water, 1g of oxalic acid per liter of water, 1g of sodium chlorite per liter of water, 0.5g of sodium nitrate per liter of water, and 1g of sodium thiosulfate per liter of water; and (2) heating the water solution with the auxiliaries at speed of 1 DEG C per minute until reaching 95 DEG C, and maintaining the temperature for 30 minutes. According to the argon bleaching and dyeing technology of the acrylic yarn, the sodium chlorite is used as the main auxiliary for oxygen bleaching and can be used for enhancing the oxidability, therefore, high bleaching effect can be realized, and the whiteness of the yarn can be improved; and the yarn is slowly cooled and washed by hot water after the oxidization, and are washed by hot water again after the oxygen bleaching, so that the problem caused by hardening in cold water can be avoided, and the oxidized acrylic yarn is fluffy, soft, full and not hard, and as a result, the quality of the acrylic yarn is improved.
Description
Technical field
The present invention relates to the textile industry argon and bleaching and dyeing the look technical field, be specifically related to a kind of Acrylic Fiber argon and bleaching and dyeing look technique.
Background technology
At present, general dye-works generally takes oxygen bleaching process for acrylic fabric in the textile industry, uses conventional oxidant H2O2 oxygen to float, but technique such as unreachable position or deal with improperly, have feel and harden, texture is coarse, can not keep the original softness of yarn, plentiful feel.This is to promote oxidation effectiveness because conventional H2O2 oxygen bleaching process need to add a certain amount of caustic soda, also need simultaneously certain high temperature just can guarantee effective decomposition of H2O2, thereby realize the whiteness that oxygen floats, but acrylic fabric is acidproof, antioxidant and common organic solvents, but alkali resistance is relatively poor.So the method that traditional handicraft can only take simple low temperature to reduce auxiliary dosage is done simple oxygen and floated, and can not realize that the abundant oxygen of acrylic fabric floats, thereby product quality of having influence on.
Summary of the invention
The purpose of this invention is to provide a kind of with sodium chlorite as main oxygenic bleaching aids, improve the whiteness of Acrylic Fiber, the Acrylic Fiber argon of Improving The Quality of Products is bleachinged and dyeing look technique.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: a kind of Acrylic Fiber argon is bleachinged and dyeing look technique, may further comprise the steps:
(1), at first described Acrylic Fiber is placed water, then adding assistant successively, described auxiliary agent is respectively chelated dispersants, consumption is every premium on currency 1g, oxalic acid, consumption is every premium on currency 1g, sodium chlorite, consumption is every premium on currency 1g, sodium nitrate, and consumption is every premium on currency 0.5g, dodium thiosulfate, and consumption is every premium on currency 1g;
(2), the aqueous solution that will be added with described auxiliary agent heats up, and heats up 1 ℃ in per 1 minute, when being warming up to 95 ℃, is incubated 30 minutes, then gets rid of the aqueous solution;
(3), the described Acrylic Fiber that will get rid of behind the aqueous solution places hot water to wash, then draining;
(4), add dodium thiosulfate, 55 ℃ of holding temperatures, are then got rid of the aqueous solution at 7 minutes time;
(5), at last with clear water to described Acrylic Fiber washing 10 minutes, then draining, thereby the Acrylic Fiber after obtaining argon and floating.
Further, comprise whitening agent in the described auxiliary agent, its consumption is: percentage by weight 0.35～0.5%.
The present invention has following beneficial effect: a kind of Acrylic Fiber argon of the present invention is bleachinged and dyeing look technique, at first takes sodium chlorite as main oxygenic bleaching aids, utilizes it to strengthen oxidisability, and the bleaching effect of high-quality improves the yarn whiteness; Then take slow cooling after oxidation finishes, the mode of hot water wash re-uses hot water wash after fully oxygen floats, and avoids meeting the sclerosis of cold water, guarantees that the Acrylic Fiber after the oxidation is fluffy, and feel is soft and smooth, plentiful, not stiffening, thus Improving The Quality of Products.In addition, the present invention has simple, the stable and maturing characteristics of technique.
The specific embodiment
The below is described in further detail present embodiment.
A kind of Acrylic Fiber argon of the present invention is bleachinged and dyeing look technique, may further comprise the steps:
(1), at first described Acrylic Fiber is placed water, then adding assistant successively, described auxiliary agent is respectively chelated dispersants, consumption is every premium on currency 1g, oxalic acid, consumption is every premium on currency 1g, sodium chlorite, consumption is every premium on currency 1g, sodium nitrate, and consumption is every premium on currency 0.5g, dodium thiosulfate, and consumption is every premium on currency 1g; Need to prove that in the present embodiment, placing of its auxiliary agent must be fed in raw material in a certain order, cannot be chaotic reinforced, in order to affect product quality;
(2), the aqueous solution that will be added with described auxiliary agent heats up, and heats up 1 ℃ in per 1 minute, when being warming up to 95 ℃, is incubated 30 minutes, then gets rid of the aqueous solution;
(3), the described Acrylic Fiber that will get rid of behind the aqueous solution places hot water to wash, then draining;
(4), add dodium thiosulfate, 55 ℃ of holding temperatures, are then got rid of the aqueous solution at 7 minutes time;
(5), at last with clear water to described Acrylic Fiber washing 10 minutes, then draining, thereby the Acrylic Fiber after obtaining argon and floating.
Comprise whitening agent in the described auxiliary agent, its consumption is according to the percentage by weight 0.35～0.5% of described Acrylic Fiber.In the present embodiment, adopt this scheme, be convenient to strengthen the bleaching effect of Acrylic Fiber, improve the yarn whiteness.
In the present embodiment, forbid to contact with acid, acidic materials, reducing substances when using argon to float, with explosion-proof, cooling must be slow after argon floats end simultaneously, otherwise can directly have influence on the feel of product.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
