Abstract
The invention discloses a surfactant for a woven fabric dye-bath retreat process and a preparation method thereof, wherein the surfactant comprises the following components in percentage by weight: 10-20 percent of sodium stearate, 20-30 percent of sodium dodecyl benzene sulfonate, 3-8 percent of polyoxyethylene nonyl phenyl ether, 30-40 percent of dispersing agent MF and the balance of water. The preparation method comprises the following steps of: adding water into the sodium stearate for dilution so as to prepare a solution with the concentration of 5-8 percent; then, adding the solution into a reaction kettle, and heating to the temperature of 70+/-5 DEG C; sequentially adding the sodium dodecyl benzene sulfonate and the polyoxyethylene nonyl phenyl ether, fully stirring and mixing; and finally, cooling to the temperature of 35+/-5 DEG C, adding the dispersing agent MF after foams naturally disappear, fully stirring and mixing to prepare the surfactant. The product can prevent the reattachment of slurry and impurities, and improve the dyeing quality.
Description
Technical field
The present invention relates to the textile dyeing and finishing manufacture field, especially relate to surfactant that a kind of woven fabric dye-bath retreat process uses and preparation method thereof.
Background technology
The dye-bath retreat process of woven fabric is that destarch, dyeing process in the traditional woven thing printing and dyeing pre-treatment process are finished in same processing is bathed.In the destarch process of woven fabric dye-bath retreat process, though special efficacy can make slurry be dissolved in the water-bath with bathing desizing agent, but inevitably have the part slurry to come off naturally because of the motoricity of fabric, and fabric weave, in the transportation inevitably the surface can attachment portion impurity destarch process can't remove.And in dye-bath retreat process, destarch dyeing is to carry out in same water-bath, dissolves or attachment phenomenon once more just might take place for the slurry or the impurity that come off in water-bath, causes the textile dyeing defect.
In view of this, the inventor studies and improves at woven fabric dye-bath retreat process specially, develops the surfactant that a kind of dye-bath retreat is used, and effectively prevents to dissolve or attachment phenomenon once more takes place for the slurry or the impurity that come off in water-bath, improve dyeing quality, this case produces thus.
Summary of the invention
The purpose of this invention is to provide surfactant that a kind of woven fabric dye-bath retreat process uses and preparation method thereof, adhere to once more, improve dyeing quality to prevent slurry or impurity.
In order to reach above-mentioned purpose, solution of the present invention is:
The surfactant that a kind of woven fabric dye-bath retreat process is used, composed of the following components by weight percentage:
Odium stearate 10%～20%;
Neopelex 20%～30%;
Polyoxyethylene nonylphenol ether 3%～8%;
Dispersing agent MF 30%～40%;
Its surplus is a water.
Described polyoxyethylene nonylphenol ether is the addition product of nonyl phenol and oxirane, and the hydroxyl value of polyoxyethylene ether is 85 ± 3mgKOH/g, and the pH value is between the 6-7, is colourless transparent liquid.
Described dispersing agent MF is dispersing agent MF (C
23H
18O
6S
2Na).
The concrete percentage by weight of described component is: odium stearate accounts for 14.5% of gross weight, and neopelex accounts for 23.4% of gross weight, and polyoxyethylene nonylphenol ether accounts for 5.6% of gross weight, and dispersing agent MF accounts for 37.8% of gross weight, and surplus is a water; Perhaps odium stearate accounts for 10.5% of gross weight, and neopelex accounts for 29.4% of gross weight, and polyoxyethylene nonylphenol ether accounts for 7.8% of gross weight, and dispersing agent MF accounts for 31.8% of gross weight, and surplus is a water.
The acting as of each component during raw material is formed:
One, odium stearate: (C
17H
35COO) Na is used for the poly-effect of emulsification, anti-freezing of controlling the foam of the process of bleachinging and dyeing and being used for the water-bath slurry;
Two, neopelex:
Structural formula
Comparatively responsive to hardness of water, be difficult for oxidation, the detergency height, easily with various additive compounds, particulate fouling, albumen dirt and oily dirt are had significant clean effect, and good especially to the cleaning function of the particulate fouling on the natural fabric, detergency strengthens with the rising of wash temperature;
Three, polyoxyethylene nonylphenol ether: C

2Na can make bright-coloured, the uniform coloring of dye shade, improves the fabric dye uptake.
The preparation method of described surfactant, its step is as follows:
The odium stearate that will account for gross weight 10%～20% earlier adds water dilutes, and is prepared into concentration and is 5%～8% solution; Then, solution is added in the reactor, be heated to 70 ℃ ± 5 ℃; Add the neopelex that accounts for gross weight 20%～30%, the polyoxyethylene nonylphenol ether that accounts for gross weight 3%～8% more successively, fully mix; At last, be cooled to 35 ℃ ± 5 ℃, treat the cancellation of foam nature after, add the dispersing agent MF that accounts for gross weight 30%～40%, after fully mixing, promptly make faint yellow emulsion----surfactant.
After adopting such scheme, the surfactant that the present invention makes plays auxiliary destarch and improves the dyeing dye uptake and improve dyeing quality in the application of woven fabric dye-bath retreat process effect specifically has following distinguishing feature: (1) has poly-, the effects such as counnter attack is stained with, dispersion, chelating of good anti-freezing; (2) improve fabric face tension force, can avoid " oligomer " such as slurry and impurity to be deposited on fabric and the dyeing machinery; (3) have stronger dispersion, level dyeing, remove the loose colour ability; (4) can effectively combine, improve cloth cover effect, tinctorial yield and the COLOR FASTNESS of institute's dyeing and weaving thing with other auxiliary agent.Therefore the present invention has wide application value in woven fabric dye-bath retreat process.
The specific embodiment
