Problems solved by technology

Coating antistatic agent is to adsorb hydrophilic groups on the surface of fibers or fabrics to increase hygroscopicity and have antistatic effect, but the hydrophilic groups are only on the surface, which is easy to wash off and has poor durability
Adding conductive substances will lead to higher costs, worse physical properties of fibers, and limited applications

Abstract

The invention discloses an antistatic treatment process for a resin-base polyester fiber, relating to the technical field of antistatic treatment of fibers. The antistatic treatment process comprisesthe following steps: (1) preparing an antistatic agent: uniformly mixing fatty amine polyoxyethylene ether, polyethylene glycol bisglycidyl ether and sodium dodecyl benzene sulfonate, sequentially andslowly adding a silane coupling agent and a polyurethane wetting dispersant, and after the adding is finished, stirring at the normal temperature; (2) carrying out mixing granulation: uniformly mixing polyethylene glycol terephthalate slices, the antistatic agent and an antioxidant 1010, standing, drying, extruding and carrying out granulation; and (3) preparing the antistatic resin-base polyester fiber: carrying out melt spinning, winding and extension machining on the granulated particulate matters, so as to obtain the antistatic resin-base polyester fiber:. The antistatic agent is firmly bound with fabrics, so that the antistatic property, friction resistance, washing tolerance and antifouling property of a resin-base polyester fiber shell fabric or fabric.

Description

Technical field: [0001] The invention relates to the technical field of fiber antistatic treatment, in particular to a resin-based polyester fiber antistatic treatment process. Background technique: [0002] Resin-based polyester fiber has insulating properties and is not easy to conduct electricity. When static electricity is obtained, it is not easy to disappear. During processing, it will affect the opening, carding and yarn winding of the fiber; when wearing clothes made of resin-based polyester fiber At the same time, the electrostatic effect also makes the clothes easy to absorb dust, and the fabric is entangled, shortening the service life. [0003] At present, the commonly used antistatic treatment methods for resin-based polyester fibers mainly include coating an antistatic agent on the surface of the fiber or fabric or adding a conductive substance. Coating antistatic agent is to absorb hydrophilic groups on the surface of fibers or fabrics to increase moisture absorptio...
