Abstract
The invention discloses a method for removing residual oxygen of a pure-cotton knitted fabric by use of heat energy after bleaching, relates to a treatment method before the dyeing and finishing of a knitted pure-cotton fabric, and particularly relates to a method for removing residual oxygen of a pure-cotton knitted fabric by use of heat energy after oxygen bleaching and by adding a high-temperature deoxidant. A fast bleaching aid SD-P4 is added, and oxygen bleaching is performed in hydrogen peroxide, and the high-temperature deoxidant is added for deoxygenation treatment. The method disclosed by the invention is mainly characterized in that oxygen is removed by use of high-temperature heat energy, liquid discharge is not required after oxygen bleaching, and residual oxygen is removed in an alkaline condition by use of residual heat energy. The oxygen removal is not required in severe conditions, the residual oxygen can be removed to below 2PPM, and the oxygen removal effect is greatly improved; and the original four-step process of pretreatment is changed into a two-step process. The deoxygenation process is moved to the later part of the first-step process and the residual heat of the first-step process is sufficiently utilized, and the technology is simplified, the flow is shortened, and the energy consumption is reduced. The method is simple and easy to implement and is an ideal pretreatment method for the dyeing and finishing of a cotton fabric, and solves the problems of the traditional treatment method.
Description
Technical field:
The present invention designs the dyeing and finishing pre-treating method of knitting pure cotton fabric, specifically is that a kind of oxygen bleaching back heat energy that utilizes adds the method that the high temperature oxygen scavenger is removed the residual oxygen of pure cotton knitted fabric again.
Background technology
In pin textile enterprise, before dyeing and finishing, all to carry out oxygen for pure cotton knitted fabric and float processing at present, materials such as the grey matter on the pure cotton knitted fabric, impurity, wax class are fallen, make fabric reach good dyeing requirement, now adopt pre-treatment to divide four procedures substantially;
One, intensification oxygen floats: add the bleaching that heats up of multiple auxiliary agent such as hydrogen peroxide at cotton and BLENDED FABRIC, temperature requirement is 98 to spend;
Two, cooling washing: after progressively being cooled to 75 degree, water flush away small part residual oxygen and alkaline agent;
Three, neutralization washing: remove residual impurity and acetic acid and be neutralized to neutrality;
Four, remove residual oxygen: use biology enzyme to remove residue minimal residue free oxygen.
The shortcoming complex procedures of this processing method, flow process is long, because 98 degree belong to high temperature, and it is bigger to consume energy, the service condition of biology enzyme deoxygenation is comparatively harsh simultaneously, needs whole working solution to be under the neutrallty condition effect of biology enzyme competence exertion, the 2nd, biology enzyme requirement working solution can not have other impurity, otherwise will lose effect by biology enzyme.Therefore must be earlier that the fabric washing is clean, working solution is that neutrality is just passable simultaneously, thereby makes that the pre-treatment process flow process is longer.In addition, this method is removed residual oxygen value only in 10PPM, and effect is not good enough.Thereby influence follow-up chromatic effect.
Summary of the invention
At the problems referred to above.It is short to the purpose of this invention is to provide a kind of flow process, and the removal method of the residual oxygen of pure cotton knitted fabric of low-carbon (LC) solves the problem that existing method exists, and improves and handles quality and follow-up dyeing quality, reduces enterprise's production cost.
Technical scheme of the present invention is as follows;
After when textile class and BLENDED FABRIC are carried out hydrogen peroxide bleaching, add high temperature deoxygenation auxiliary agent, because oxygen floats the back working solution for alkalescence, utilize compound valence transition consume free oxygen between the manganese compound simultaneously, and can oxygen consumed low value to the utmost point, arrive below the 2PPM.The washing that neutralizes then, entry immediately can be dyeed, and is easy to operation.
The present invention is two procedures;
One, intensification oxygen floats
Two, deoxidation treatment
Place continuous oxygen to float production equipment in the raw material fabric, the bath raio of employing is 1: 8.Add and float auxiliary agent SD-P4 fast.Floating auxiliary dosage fast is 2% of fabric weight.Add hydrogen peroxide again.The addition of hydrogen peroxide is 5% of fabric weight, and the hydrogen peroxide specification is technical grade.Be warmed up to 80-85 ℃ then.Cycle operation insulation 50 minutes.Namely finish first procedure.Add the high temperature oxygen scavenger then and carry out deoxidation treatment.The addition of high temperature oxygen scavenger is the 0.15-0.5% of fabric weight.Deaeration time is 15-30 minute.Wash neutralisation treatment again.The bath raio of washing neutralization is 1: 10.PH value until processed fabric reaches neutral.Namely finish second operation work.
High temperature oxygen scavenger prescription
Above three kinds of materials are made the high temperature oxygen scavenger through stirring.
The principle of the invention be utilize organo-manganese compound carry out under certain condition the compound valence state between oxygen consumed when changing.Namely under alkali condition, the divalence organo-manganese compound plays pendulum, and meets free oxygen oxidation immediately and generates the manganic compound, and this process consumes low concentration and residual hydrogen peroxide; Manganic is in unsettled transition valence state subsequently, and the manganic ion generates tetravalence manganese compound precipitation through hydrolysis, precipitation and oxidation, and this process is to generate new compound, stably is scattered in the water after combining with dispersant; Carry out wastewater treatment process at last.Whole chemical reaction is the residual oxygen of catalytic decomposition under heated condition, and the condition of catalytic reaction is chemicals Organic Manganese catalyst, remaining heat energy, alkaline working solution.Thereby the residue of handling the back hydrogen peroxide under this condition is relatively low.
Main feature of the present invention is to utilize the high temperature heat deoxygenation, does not need discharge opeing after oxygen floats, and utilizes residue heat energy to carry out the removal of residual oxygen under alkali condition.Need be in deoxygenation under the harsh conditions comparatively, and can make residual oxygen be removed to limit, can be down under the 2PPM, improve deaerating effect greatly, and be condensed to two-step method by four step of original pre-treatment operation method.Deoxidation step is moved to the after-heat that first step operation back segment takes full advantage of first step operation simplified technology, shortened flow process, reduced energy consumption simultaneously.This method is simple, and is easy to implement.It is a kind of desirable COTTON FABRIC dyeing and finishing pre-treating method.Solved the problem that traditional treatment method exists.
The present invention does not have accompanying drawing
