Abstract
The invention relates to a multi-functional dye leveler for one bath degreasing dyeing of polyester fiber and a preparation method thereof. The dye leveler comprises PEG 300 lauric acid ester, sodium lignin sulfonate, soil temperature 60, polyaspartate, calcined soda and water, has the functions such as migration, scattering, chelating, degreasing, purging and the like, can be used for dying polyester fiber, simplifies the traditional technology and is conducive to energy conservation and emission reduction.
Description
Technical field
The present invention relates to reagent of a kind of textile dyeing and finishing industry and preparation method thereof, particularly a kind of multi-functional levelling agent that is used for the dyeing of polyester fiber one-bath deoiling and preparation method thereof.
Background technology
Dyeing is the important composition one's duty of textile industry, is again the industry that energy consumption is higher, quantity of wastewater effluent is bigger.Advanced country's ton fiber dyeing water amount is about 100 tons, and China is generally the 300-400 ton, and therefore, it is imperative that dyeing is carried out energy-saving and emission-reduction.
Dyeing is carried out energy-saving and emission-reduction work,, water saving efficient except researching and developing, energy-saving equipment are developed and are applied outside the practical new technology of energy-conservation, water saving, and adopting efficient, environmental protection, water saving, energy-conservation dying material is the most effective way of present stage, and less investment, instant effect.
Terylene is world wide production maximum, most widely used synthetic fiber kind, and terylene accounts for more than 60% of world's synthetic fiber output at present.Be used for textiles and other industrial fibre goods such as dress material, bedding, various trimming cloth, defence and military particular fabric in a large number, as filtering material, insulating materials, tire cord, conveyer belt etc.In recent years, along with domestic economy maintains sustained and rapid growth and the improving constantly of domestic consumption of resident ability, the demand of domestic regional polyester staple fiber also constantly increases.China's terylene series of products production capacity is increasing with surprising rapidity, and increasing rapidly of polyster fibre production capacity makes China develop into the important processing base of world's terylene series products just gradually.
Terylene needs to add a certain amount of finish in spinning and weaving process, these finishes mainly become and are mineral oil, white oil and lubricant etc.If these finishes are not divested dyeing specks such as will causing dyeing look flower, oil mark from fiber, so in the traditional handicraft, polyster fibre (fabric) will carry out the boiling-off oil removing before dyeing.
Both at home and abroad the high temperature levelling agent that generally adopts of textile printing and dyeing industry is generally formed by polyether-type nonionic or polyether-type anion surfactant, swelling agent and composition thereof a few days ago, as: number of patent application is: 87101577 described " a kind of levelling agent and method for makings thereof ", the vitrification point that such levelling agent is based on the solubilising of DISPERSE DYES and peptizaiton and reduction polyster fibre designs, shortage is removed functional oil and a flat iron plate for making cakes closes ability, is not suitable for co-bathing dyeing.
Summary of the invention
First goal of the invention of the present invention is to be to overcome the deficiencies in the prior art part, provide a kind of have except that functional oil and a flat iron plate for making cakes close ability, be applicable to the dye leveller of co-bathing dyeing.
Second goal of the invention of the present invention is to provide a kind of rational practicable preparation method for above-mentioned dye leveller.
First goal of the invention of the present invention is achieved through the following technical solutions: a kind of multi-functional dye leveler, and its constituent and percentage by weight thereof are:
PEG300 laurate 10%-20%
Sodium lignin sulfonate 2%-10%
Soil temperature 60 3%-8%
Poly-aspartic-acid 2%-5%
Soda ash 3%-8%
Water 52%-70%
Each component and percentage by weight thereof are in the above-mentioned PEG300 laurate:
PEG300 41%-58%
Laurate 39%-56%
P-methyl benzenesulfonic acid 0.4%-1.1%
2.6-BHT 0.5%-1.2%

Second goal of the invention of the present invention realizes by the following method: a kind of hydrophilic softening agent preparation method, and its step comprises:
1) preparation of PEG300 laurate:
In stainless steel cauldron, the PEG300, laurate, the 2.6-BHT that add formula ratio, logical nitrogen also is warmed up to 80-100 ℃, add p-methyl benzenesulfonic acid, continue to be warming up to 110-130 ℃, vacuumize insulation 5-8 hour, cool to then below 40 ℃, add triethanolamine, then in and 20 minutes, filter blowing.
2) multi-functional levelling agent is composite
With PEG300 laurate, sodium lignin sulfonate, soil temperature 60, poly-aspartic-acid and the water of formula ratio, drop in the stirred tank, stir, slowly adding the soda ash adjust pH is 6-7, filters discharging and can then.
Multi-functional dye leveler of the present invention has a flat iron plate for making cakes and closes multiple functions such as dispersion, level dyeing, oil removing, washing.Can be used for the dyeing of polyester fiber one-bath deoiling.Adopt the novel multifunctional levelling agent, can in dyeing course, the finish on the fabric be divested, and it is dispersed in the dye liquor, and avoid back being stained with, simultaneously it is to the efficient dispersion of DISPERSE DYES with move the ability of dying, can effectively prevent uneven dyeing, avoid look flower, make one-bath deoiling dyeing become possibility, thus shortened process greatly, realize energy-saving and emission-reduction, production efficiency is provided.Preparation method of the present invention simplifies traditional handicraft, helps energy-saving and emission-reduction, reduces environmental pressure, enhances productivity.
