Crease-resistant dressing liquid for cellulose fabric and its preparing method and use

Abstract

The invention relates to anti-crease finishing liquid of cellulose fiber fabrics, the method for preparing the finishing liquid and the use of the finishing liquid. A formula of the finishing liquid comprises: 2D derivant no-ironing resin 60-160g / l, catalyst 4-8g / l, nanometer titanium dioxide 0.05-2.0g / g, dispersant 0.05-2.0g / l and penetrating agent 1.0-2.0g / l, wherein the 2D derivant no-ironing resin is modified 2D or derivant no-ironing resin, the catalyst is one of magnesium chloride, zinc nitrate, ammonium chloride and aluminum sulfate, the average grain diameter of the nanometer titanium dioxide is 20-100nm, the dispersant is one of sodium polyphosphate, PEG-1000, sodium dodecyl benzene sulfonate, sodium dodecyl sulfonate and tween 80, the penetrating agent is one of penetrating agent JFC, penetrating agent M and penetrating agent T. The method for preparing is realized through mixing with high speed according to the formula of the finishing liquid. The use of the finishing liquid adopts a twice dipping twice rolling fishing technique to carry out anti-crease finishing for the cellulose fiber fabrics.

Problems solved by technology

However, formaldehyde-free finishing agents are much different from traditional N-methylolamide finishing agents in terms of reactivity, price and source of raw materials, so it is difficult to replace such resins (such as 2D or modified 2D) in terms of comprehensive performance. resin, etc.)

[0005] Experiments have shown that after anti-wrinkle finishing with modified 2D resin finishing liquid, the strength of cotton and other cellulose fiber fabrics will be greatly lost, which seriously affects their wearability.

The study found that there are two main reasons for the decline in strength: one reason is that this type of finishing agent forms intramolecular and intermolecular crosslinks inside cotton and other cellulose fibers, which limits the strength of cellulose in cotton and other cellulose fibers. The mobility of macromolecular chain segments causes stress concentration; another reason is that most of the catalysts used in traditional finishing methods are acidic or latent acidic catalysts, and acidic catalysis will cause the degradation of cellulose macromolecular chains, causing cotton and other cellulose Acid damage to fibers

In order to improve the elastic properties of cotton and other cellulose fiber fabrics, the former is unavoidable because of the decrease in strength caused by wrinkle-resistant finishing; as for the latter, there are no literature reports with good solutions.
