Problems solved by technology

However, the current graft cross-linking method uses chemical graft cross-linking method, the reaction conditions are harsh, and slight changes in the reaction system will affect the cross-linking reaction results.
In addition, the active cross-linking agent used in the chemical graft cross-linking method is expensive and difficult to recycle, and the treatment of organic waste liquid rich in cross-linking agent is also very difficult, which is likely to cause environmental pollution and product pollution

Embodiment 1

[0016] The polyethylene glycol with a molecular weight of 4000 is prepared into a solution with a concentration of 40%; the polyester fiber is immersed in the prepared polyethylene glycol solution; after being taken out, it is irradiated with a 1.5MeV electron accelerator, and the irradiation dose is 60kGy. Rinse with water after irradiation and dry in an oven at 90°C. After drying, polyester fiber with temperature regulation function is obtained.

[0017] Put the prepared polyester fiber in the refrigerator for 30 minutes, take it out and put it in an oven at 40°C, the temperature of the fiber keeps rising, when it reaches 28°C, the temperature is maintained for 10 minutes, and then the temperature of the fiber continues to rise to 40°C . It is indicated that the prepared fibers absorb heat at 28°C and can maintain for a period of time, so that they have the function of temperature regulation.

Embodiment 2

[0019] The polyethylene glycol with a molecular weight of 4000 was prepared into a solution with a concentration of 40%; the polypropylene fiber was dipped into the prepared polyethylene glycol solution; after being taken out, it was irradiated with a 1.5MeV electron accelerator, and the irradiation dose was 40kGy. Rinse with water after irradiation and dry in an oven. After drying, it can be obtained with temperature adjustment function of polypropylene fibers.

[0020] Put the prepared polypropylene fiber in the refrigerator for 30 minutes, take it out and put it in an oven at 90 °C, the temperature of the fiber is rising continuously, and the temperature is maintained for 10 minutes when it reaches 28 °C. Then, the fiber temperature continued to rise to 40°C. It is indicated that the prepared fibers absorb heat at 28°C and can maintain for a period of time, so that they have the function of temperature regulation.

Abstract

The invention discloses a composite fiber production method having the temperature-regulating function, which comprises the following steps that: a polyethylene glycol with a molecular weight of 1000 to 6000 is prepared into an aqueous solution with a concentration of 20 to 40 percent, the aqueous solution is then evenly coated on the surface of the composite fiber, the composite fiber coated with the solution is irradiated with electron beams of 200keV to 5MeV through an irradiation device, the irradiation dose ranges from 5 to 150kGy, and the irradiated composite fiber is rinsed by clear water and is then dried. The composite fiber production method having the temperature-regulating function has advantages of simple production process, easy process control, rather low cost and non environmental pollution.

Description

technical field [0001] The present invention relates to functional fiber technology, in particular to a production method of composite fiber with temperature regulation function. Background technique [0002] There are two main production methods of fibers with temperature regulation function, one is the encapsulation method, and the other is the grafting and cross-linking method. The current graft cross-linking method adopts a chemical graft cross-linking method, and the reaction conditions are harsh, and slight changes in the reaction system will affect the result of the cross-linking reaction. In addition, the active cross-linking agent used in the chemical graft cross-linking method is expensive and difficult to recycle, and the treatment of organic waste liquid rich in cross-linking agent is also difficult, which is likely to cause environmental pollution and product pollution. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the purpose of the...
