Problems solved by technology

Although there are many kinds of anti-mosquito agents or anti-mosquito drugs, many of the commonly used anti-mosquito agents in daily life are extracted from plants, which have the characteristics of low melting point and boiling point, volatile and easy to decompose at high temperature, so blending and melting There are not many types of mosquito repellants available for spinning

Embodiment 1

[0023] After the purified 5 grams of FWJ and 495 grams of polypropylene resin slices were stirred and mixed, they were fed into a twin-screw extruder for blending and granulation to obtain mosquito-resistant spinning chips with a mosquito repellent content of 1%. Slicing method for melt spinning. The feeding screw speed is 50r / min, the main screw speed is 120r / min, the twin-screw extruded filaments are cooled in a water bath, and the anti-mosquito masterbatch is obtained by pelletizing with a pelletizer. The cutting speed is 400r / min, and the twin-screw extrusion The temperature of each zone of the machine is as follows:

[0024]

[0025] The above-mentioned anti-mosquito slices are spun on the spinning machine with full slice method, the pump supply rate is 4g / min, and the anti-mosquito primary fibers are prepared under the condition of cold air blowing, the component pressure is about 40 kg, and the winding speed is 400 m / min . The spinning temperature is as follows:

Abstract

The invention relates to a method for preparing a polypropylene fiber with anti-mosquito function, which comprises the following steps of: (1) mixing a mosquito repellent and dried polypropylene resin slices and preparing anti-mosquito master batches or anti-mosquito spinning slices by using a double-screw extruder; (2) blending the prepared anti-mosquito master batches and pure polypropylene resin slices for melt spinning, or directly performing melt spinning on the prepared anti-mosquito spinning slices by a whole section method; and (3) drawing an as-spun fiber for shaping. The method is simple and suitable for industrial production; and the prepared fiber has good anti-mosquito effect and the washing fastness of the fiber is improved.

Description

technical field [0001] The invention belongs to the field of polypropylene fiber preparation, in particular to a preparation method of polypropylene fiber with anti-mosquito function. Background technique [0002] In real life, especially in hot summer, people are often bitten by mosquitoes, which spread diseases through contact with human blood and affect human health. In the prior art, people generally use some anti-mosquito agents to post-treat the fibers or fabrics, or use microcapsules to coat the anti-mosquito drugs, and then arrange them on the surface of the fibers or fabrics. In this method, the anti-mosquito agents or The anti-mosquito drug is only attached to the surface of the fiber and has poor washing resistance. [0003] The insecticide or anti-mosquito agent is added to the chips before spinning for blending and melt spinning, and the anti-mosquito functional components are evenly dispersed in the fiber instead of just adhering to the fiber surface, which ca...
