Abstract

The invention relates to a wetting agent for textile fibers and a preparation method thereof. The wetting agent for textile fibers is mainly composed of 1,2-epoxy dodecane, hexane, sodium hydroxide, water absorbent and the like. The wetting agent for textile fibers has the characteristics of small surface tension, high wetting speed, high wetting uniformity, obvious wetting effect and the like.

Description

A kind of fabric fibre wetting agent and preparation method thereof

Technical field

The present invention relates to a kind of fabric fibre with wetting agent and preparation method thereof, belonged to dope dyeing auxiliary agent technical field.

Background technology

Obtaining of various fabric colors, the best approach are to depend on dyeing back arrangement, and obtain desirable effect then requisite in dyeing course is dewing operation to strong thing.And in the dewing operation of existing dyeing back arrangement, people often pay close attention to dewing equipment, by equipment update and control dewing effect and the purpose that reaches desirable, from some publish both at home and abroad with the relevant patent of reporting and paper all relate to the soaking device that uses in a kind of textile dyeing, a kind of quantitative wetting apparatus of textile dyeing etc.

Above-mentioned these argumentations all are the even dewing problems that solves fabric from the angle of equipment, yet in existing fabric, nylon fabric, acrylic fabric are the hydrophobic fiber fabric, and often greasy dirt are difficult to thoroughly remove in weaving process.The viscose glue kind fabric is artificial fibre, when fiber is made and be mixed with hydrophobic impurity, often also the greasy dirt that speckles with is difficult to remove in weaving process.All-cotton fabric itself contains more hydrophobic impurity and grease, and these impurity and grease remove when pre-treatment that difficulty is bigger, and it is inconsistent that these have all influenced the fabric fibre capillary effect, causes difference and the unequal problem of dyeing of the water capacity in the arrangement of dyeing back.

And existing dyeing back arrangement is to the fountain solution of fabric, its Main Ingredients and Appearance is water, be added with different a little auxiliary according to the difference of fabric and the difference of dyestuff in its water, the surface tension of this fountain solution is big, be difficult to some hydrophobic fabrics or contain the higher fabric of grease even dewing fast, so, only by the different improved control to the equipment of soaking, be not reach ideal uniform dewing effect.

Summary of the invention

Technical problem to be solved by this invention provides that a kind of surface tension is low, dewing fast, evenly, the fountain solution of characteristics such as the dewing effect is remarkable.

For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions, it is characterized in that this fabric fibre with wetting agent mainly by: 1.2-epoxy radicals dodecane, hexane, NaOH, water absorbing agent, water etc. are formed.

A kind of fabric fibre wetting agent and preparation method thereof, this fabric fibre with wetting agent by its molar equivalent ratio is: 1.2-epoxy radicals dodecane 0.2～0.8mol; Hexane 1.0～3mol; NaOH 0.2～0.8; Water absorbing agent 0.2～0.5mol; Compositions such as excess water.

A kind of fabric fibre wetting agent, its water absorbing agent are a kind of of glycerine, calcium chloride or magnesium chloride.

A kind of fabric fibre wetting agent, its preparation method is:

The mixture that under stirring condition, adds hexane, NaOH in the 1.2-epoxy radicals dodecane, in about 70 ℃, stir again, obtain the decyl ethylene glycol ether until reacting completely, in this reaction, add water absorbing agent while stirring again, namely get goods after stirring, during use, add suitable quantity of water by dyeing.

The specific embodiment

1, accurately preparation by its molar equivalent ratio is: 1.2-epoxy radicals dodecane 0.5mol; Hexane 1.4mol; NaOH 0.6mol; Water absorbing agent 0.3mol; Excess water, standby.

2, preparation method

The mixture that under stirring condition, adds hexane, NaOH in the 1.2-epoxy radicals dodecane, in about 70 ℃, stir again, obtain the decyl ethylene glycol ether until reacting completely, in this reaction, add water absorbing agent while stirring again, namely get goods after stirring, during use, add suitable quantity of water by dyeing.
