Description
Technical field
The present invention relates to the processing method of a kind of dacron destarch and dyeing, particularly a kind of desizing liquid for Dacron and the application in dacron destarch and dyeing processing thereof belong to the textile dyeing and finishing technical field.
Background technology
In textile industry, the terylene woven generally all contains chemical sizwe, main chemical sizwe has polyvinyl alcohol, polyacrylate and modifier etc., the existence of dacron slurry can directly have influence on the processing of fabric and take performance, unclean as destarch, can produce dyeing inhomogeneous, dyeing articles COLOR FASTNESS variation, also can have influence on the permeance property of fabric, make the feel hardening of fabric etc.Therefore, dacron adds man-hour in printing and dyeing, and the general manufacturing procedure that all adopts first destarch to dye again is to guarantee the quality of fabric.
At the characteristics of dacron sizing material, desizing method commonly used has alkali destarch, alkali, surfactant destarch, the destarch of alkali hydrogen peroxide etc.Wherein alkali hydrogen peroxide destarch fado is used to contain dacron, as the continuous desizing of polyester cotton blending or intertexture.
Dyeing of PET fabric generally adopts DISPERSE DYES high-temp dyeing under faintly acid or alkali condition.Destarch and dyeing all can be finished on heatable intermittent apparatus, and typical manufacturing procedure is: destarch processing, hot wash 1-2 time, dyeing, reduction cleaning, washing.These method technologies are loaded down with trivial details, and water consumption is big, and wastewater discharge is big, long processing time, thermal energy consumption height, inefficiency.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of and can effectively shorten dacron dyeing and finishing technology flow process, reduce consumption of heat energy, reduce discharge of wastewater, the dacron destarch of increasing work efficiency and the processing method of dyeing.
For achieving the above object, the technical solution used in the present invention is: a kind of desizing liquid for Dacron is provided, and it comprises that mass concentration is 0.05～0.5% SODIUM PERCARBONATE and tetraacetyl ethylene diamine, and the mass ratio of SODIUM PERCARBONATE and tetraacetyl ethylene diamine is 2: 1; The pH value of desizing liquid is 11～12.
The present invention provides the application of above-mentioned desizing liquid for Dacron simultaneously, its method is, fabric desizing and dyeing are carried out with bathing, dacron is placed heatable batch (-type) dyeing installation, add desizing liquid for Dacron, DISPERSE DYES and alkaline levelling agent, the pH value of regulating the destarch dyeing liquor with NaOH is 11～12, and destarch dyeing treatment temperature is 120～130 ℃, and the destarch dyeing processing time is 60～90 minutes.
The present invention also provides the another kind of application process of above-mentioned desizing liquid for Dacron, dacron is placed heatable batch (-type) dyeing installation, add desizing liquid for Dacron and carry out the fabric desizing processing earlier, the destarch treatment temperature is 85～105 ℃, and the destarch processing time is 30～90 minutes; Adding in the destarch raffinate fabric heavily is that the alkaline levelling agent of 0.05～8% DISPERSE DYES and 0.1～0.3% carries out coloration of textile materials and handles again, and the dyeing treatment temperature is 120～130 ℃, and the dyeing processing time is 60～90 minutes.
Compared with prior art, the present invention has the following advantages:
1. SODIUM PERCARBONATE can resolve into hydrogen peroxide under alkali condition, tetraacetyl ethylene diamine can generate Peracetic acid with the hydrogen peroxide effect simultaneously, hydrogen peroxide and Peracetic acid all are oxidants, can carry out oxidation destarch effect to the slurry on the dacron, make slurry oxidative degradation become small-molecular weight by macromolecule, remove from fabric easily, therefore, the destarch efficient of dacron is improved.
2. the concentration and the quality of SODIUM PERCARBONATE used in the present invention and tetraacetyl ethylene diamine compare control range, do not influence and dye polyster fibre on the DISPERSE DYES, therefore, can in desizing liquid, directly add DISPERSE DYES, or DISPERSE DYES and desizing liquid bath together, finish dyeing of PET fabric.
3. the consumption of energy conserve water in the dacron dyeing course reduces consumption of heat energy, and the consumption of water is 1/2～3/5 of a prior art, has reduced the discharging of dyeing waste water, and simultaneously, thermal energy consumption is 50～70% of a prior art.
4. because non-water-soluble polyvinyl alcohol pulp is non-degradable under alkali condition, therefore, existing destarch technology is difficult to the removal of polyvinyl alcohol pulp, causes dyeing of PET fabric to form color dot or look flower easily.And the technology of the present invention utilizes method for oxidation to remove slurry, and slurry adhesion to polyster fibre after oxidative degradation descends, and is therefore very little to the influence of dyeing, is difficult for forming dyeing color dot or look flower, solved dacron destarch problem of difficult.
