Problems solved by technology

[0002] Fiber is a filamentous substance that is natural or synthetic. Fiber is ubiquitous in modern life, and it is especially widely used in the textile industry. There are more and more clothes made of fiber, but the insulation of traditional fiber manufacturing raw materials The effect is poor, and the toughness is low, easy to break, affecting the quality of garments. At present, all parts of the world are competing to develop new thermal insulation materials to solve the disadvantages of traditional raw materials and meet the needs of production and life.

Abstract

The invention discloses an aerogel PET (polyethylene terephthalate) master batch and a manufacturing technique thereof. The manufacturing technique comprises the following steps: uniformly mixing an activator, a dispersing agent and an aerogel, and carrying out activating treatment to obtain a mixture A; adding PET (polyethylene terephthalate) slices into the mixture A, uniformly mixing, and drying at 120 DEG C for 6 hours to obtain a mixture B; and putting the dried mixture B into double screw extruder, and carrying out granulation under the frequency of 32.5-35.5Hz. By using the aerogel and PET slices as the generation raw materials, the favorable heat-insulating property of the aerogel and the characteristics of high toughness and high wear resistance of the PET material are combined, so that the obtained aerogel composite fibers have high toughness. The heat conductivity coefficient of the adopted aerogel is 0.019 W/(m.K) which is much lower than the heat conductivity coefficient 0.092 W/(m.K) of pure wool, and therefore, the off-the-rack suit prepared from the fibers made from the aerogel PET master batch has excellent heat-insulating property.

Description

technical field [0001] The invention relates to a fiber raw material, in particular to an airgel PET master batch and a manufacturing process thereof. Background technique [0002] Fiber is a filamentous substance that is natural or synthetic. Fiber is ubiquitous in modern life, and it is especially widely used in the textile industry. There are more and more clothes made of fiber, but the insulation of traditional fiber manufacturing raw materials The effect is poor, and the toughness is low, easy to break, affecting the quality of garments. At present, all parts of the world are competing to develop new thermal insulation materials to solve the disadvantages of traditional raw materials and meet the needs of production and life. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and propose a kind of fiber manufacturing raw material which has good thermal insulation effect, is easy to weave, a...
