Abstract
The invention discloses an environment-friendly and efficient biparental levelling agent, which is prepared by a method comprising the following steps: carrying out heating and refluxing on fatty acid and a polyol mixture for esterification reaction under the catalytic condition of concentrated sulfuric acid; removing the product out of a refluxing device after reaction is ended and maintaining the temperature at 120-160 DEG C; and adding sodium lauryl sulfate, glutamic acid and triethanolamine, stirring and mixing the raw materials for 4-6 hours, and adjusting the pH to be neutral to obtain the environment-friendly and efficient biparental levelling agent. The levelling agent has relatively high affinity on fabric and dye, and has efficient levelling property. The preparation raw materials do not contain harmful substances of formaldehyde and the like, so that the levelling agent is an environment-friendly levelling agent.
Description
Technical field:
The present invention relates to textile auxiliary field, particularly a kind of environment-friendly high-efficiency parental type levelling agent.
Background technology:
In the dyeing course of fabric, dyeing non-uniform phenomenon very easily there is, it may appear that such as barriness or specking etc., the quality of fabric can be made to be subject to strong influence. The structure that the reason one side that appearance is dyeed uneven is probably fabric itself is uneven, it is also possible to be dyeing course misoperation. Dyeing course adds levelling agent, is a kind of simple and effective raising dyeing uniformity, and ensures the method that staining efficiency is higher.
Levelling agent it is generally required to possess control dyestuff adsorbed by fabric speed, dyestuff can be promoted to be evenly distributed on fabric and not affect the features such as color fastness. Can be divided three classes according to the type of action of levelling agent: parent's dye-type levelling agent, parent's textile type levelling agent and parental type levelling agent. Wherein, parent's dye-type levelling agent refers to that levelling agent is to levelling agent more than the affinity type to fabric of the affinity of dyestuff, otherwise, then be close textile type levelling agent. And parental type levelling agent refers to the class levelling agent that dyestuff and fabric are respectively provided with good affinity. About the research of all kinds of levelling agents all to be paid close attention to widely, and achieve substantial amounts of achievement in research.
At present, what need most solution is the environmental issue about levelling agent, and on market, most levelling agent all contains the harmful components such as formaldehyde, after being used on fabric, can human body be caused serious injury. the preparation method that Chinese patent CN201210076624.2 discloses a kind of novel levelling agent, it is characterized in that it comprises the steps: 1, the synthesis of hydroxymethyl alkyl phenol polyethenoxy ether: be 1:0.2��2 by the mol ratio of alkylphenol polyoxyethylene Yu formaldehyde, it is 323.0g:4.0g by the proportioning of alkylphenol polyoxyethylene with potassium hydroxide or sodium hydroxide, take alkylphenol polyoxyethylene, add formaldehyde, add potassium hydroxide or sodium hydroxide, it is distill at 80 DEG C��125 DEG C in reaction temperature, reaction, occur to without distillation, obtain hydroxymethyl alkyl phenol polyethenoxy ether, 2, it is 1:0.1��16 by the mass ratio of hydroxymethyl alkyl phenol polyethenoxy ether Yu higher fatty acid salt, by hydroxymethyl alkyl phenol polyethenoxy ether and the mixing of higher fatty acid salt boiling water bath, obtains levelling agent. levelling agent prepared by the method has good even dyeing effect but uses in preparation process and arrived formaldehyde, can be levelling agent still removing residue formaldehyde.
Chinese patent CN200810032831.1 discloses a kind of phthalocyanine reactive dyeing leveling agent, including: di-2-ethylhexylphosphine oxide naphthalene sulfonate 10-15%, lignosulfonates 15-20%, carboxymethyl cellulose 2-5%, carbamide 2-5%, surplus is water;Described percentage ratio is weight percentage. Dyestuff is had excellent lyotropy by the present invention so that it is will not precipitate out under adding electrolytical situation, thus obtain splendid even dyeing effect. Although this levelling agent environmental protection, not containing the harmful substances such as formaldehyde, but its specific aim is too strong, even dyeing effect more has much room for improvement. So, the levelling agent preparing efficient environmental protection is still challenging to research work.
Summary of the invention:
The present invention relates to a kind of environment-friendly high-efficiency parental type levelling agent, fabric and dyestuff are respectively provided with higher affinity by this levelling agent, it is possible to make dyestuff be evenly distributed in fabric face, have efficient homogenized diet. Prepare and raw material does not contain the harmful substances such as formaldehyde, be the levelling agent of a kind of environmental protection, be suitable for industrialization large-scale production.
For achieving the above object, the present invention is by the following technical solutions:
A kind of environment-friendly high-efficiency parental type levelling agent, it is characterised in that be prepared from by following methods: be heated to reflux when sulphuric acid catalysis esterification by fatty acid and polyalcohols mixture; Removing reflux after having reacted, maintain temperature at 120-160 DEG C, add sodium lauryl sulphate, glutamic acid and triethanolamine, after stirring mixing 4-6h, regulating pH be neutrality, both described environment-friendly high-efficiency parental type levelling agent.
Preferred as technique scheme, described fatty acid is the one in oleic acid, stearic acid or linoleic acid.
Preferred as technique scheme, described polyalcohols mixture is the mixture that mol ratio is 2:1 of polytetramethylene glycol and polypropylene glycol.
Preferred as technique scheme, the mass ratio of described fatty acid and polyalcohols mixture is 1:1.2-1.5.
Preferred as technique scheme, the response time of described esterification is 12-18h.
Preferred as technique scheme, the mass ratio of described fatty acid and sodium lauryl sulphate is 1:1.2-1.5.
Preferred as technique scheme, the mass ratio of described fatty acid and glutamic acid is 3-4:1.
Preferred as technique scheme, the mass ratio of described fatty acid and triethanolamine is 4-5:1.
The method have the advantages that
The polyesters material that this environment-friendly high-efficiency parental type levelling agent obtains after being reacted with polyalcohols compound by fatty acid is primary raw material, dyestuff and fabric are all had stronger affinity by this levelling agent, dye for fabrics can be effectively facilitated be distributed uniformly and in fabric, improve the uniformity of dyeing. Preparation process is selected raw material do not comprise the harmful substances such as formaldehyde, environmental protection, the healthy of people will not be worked the mischief. The reaction condition of this levelling agent is gentle simultaneously, and preparation method is simple, it is easy to operation, it is possible to very big raising preparation efficiency, saves preparation cost, is very suitable for large-scale industrial production.
