Description
Technical field
The present invention relates to a kind of cationic antistatic agent of the durability for dacron and preparation method thereof.
Background technology
Fabrics of polyester is high, crease-resistant, wear-resisting with its intensity, dimensionally stable, quick-drying washable, exempt from the premium properties such as flatiron and become one of product that people favor most, be widely used in clothes, decoration and fabrics for industrial use.But terylene is hydrophobic fibre, lack the moisture absorption group, belong to non-conductor; Hydroscopicity is low; Therefore, himself or easily produce static when the friction of itself and other object, if these electrostatic charges can not be scattered and disappeared rapidly by all means, will on material and processing equipment, accumulate gradually, increase, cause various obstacles and harm.
In the tradition antistatic additive, cationic antistatic additive is most widely used general, strong to the fiber sorptive force, still shows good antistatic effect when low humidity.Cationic antistatic additive is generally used at most with quaternary ammonium salt, this class surfactant is except good antistatic property, also there is certain washable ability, generally can be washable 5～10 times, but the fiber after processing or the feel of fabric are not fine, and its adhesive force to equipment surface is larger, affects consecutive production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of washable cationic antistatic agent of the durability for dacron more than 30 times.
But another technical problem to be solved by this invention is to provide the preparation method of a kind of quantity-produced for the durability cationic antistatic agent of dacron.
