Problems solved by technology

Especially when the human body is in a hot or humid environment for a long time and cannot expel moisture from the body in time, the surface temperature of the human body will rise and perspiration will occur, which will cause the "micro-environment" under the clothes to feel obviously hot and humid. The human body will have obvious stuffy and uncomfortable feeling, which will definitely damage the health in the long run! Especially for the crowd who have been engaged in field work activities for a long time, it is necessary to develop a kind of clothing that can adjust temperature and absorb moisture.

Embodiment 1

[0031] (1) Burn 500g of volcanic ash powder with a particle size of 4-10μm in a muffle furnace at 800°C for 1.0h. After cooling, place the volcanic ash in 150ml of ethanol solvent, add 100g of organic silicon treatment agent KH550 and heat to reflux for 4h. Filter, wash, and dry for later use;

[0032](2) Weigh 500g of the pretreated activator and 500kg of nylon 66 salt, stir, mix and disperse evenly in a storage tank, and then undergo a chain condensation polymerization process (that is, polymerization + post-condensation reaction, that is, a horizontal tube continuous polycondensation process), so that nylon The concentration of the aqueous solution of 66 salt is maintained at about 60%. The above-mentioned materials are continuously sent into the preheater through the plunger pump, and after being preheated to 215°C, they enter the first high pipe, and are continuously pushed into the first horizontal pipe and the second horizontal pipe, and the first high pipe enters the h...

Embodiment 2

[0037] (1) Burn 500g of volcanic ash powder with a particle size of 2-6μm in a muffle furnace at 600°C for 4h, put the volcanic ash in 150ml of ethanol solvent after cooling, add 200g of organic silicon treatment agent KH560 and heat to reflux for 5h, filter , washed and dried for later use.

[0038] (2) Weigh 500g of the processed activator and 100kg of nylon 66 salt, stir, mix and disperse evenly in a storage tank, and then go through the chain condensation polymerization process (that is, polymerization + post-condensation reaction, that is, horizontal tube continuous polycondensation process), to make nylon 66 The concentration of the aqueous salt solution is maintained at around 60%. The above-mentioned materials are continuously sent into the preheater through the plunger pump, and after being preheated to 220°C, they enter the first high pipe, and are continuously pushed into the first horizontal pipe and the second horizontal pipe, and the first high pipe enters the ho...

Embodiment 3

[0043] (1) Burn 500g of volcanic ash powder with a particle size of 0.5-3µm in a muffle furnace at 1000°C for 0.5h. After cooling, place the volcanic ash in 150ml of ethanol solvent, add 400g of organic silicon treatment agent KH570 and heat to reflux for 6h. Filter, wash and dry for later use.

[0044] (2) Weigh 500g of the processed activator and 50kg of nylon 66 salt, stir, mix and disperse evenly in a storage tank, and then go through a specific chain condensation polymerization process (ie, polymerization + post-condensation reaction, that is, horizontal tube continuous polycondensation process), so that The aqueous solution concentration of nylon 66 salt is maintained at about 60%. The above-mentioned materials are continuously sent into the preheater through the plunger pump, and after being preheated to 225°C, they enter the first high pipe, and are continuously pushed into the first horizontal pipe and the second horizontal pipe, and the first high pipe enters the hor...

Abstract

The invention relates to the field of textile materials, and provides a temperature-adjustable filament and a manufacturing method thereof, aiming to overcome the defects of other temperature-adjustable products on the current market in functional durability. The temperature-adjustable filament is prepared from active agents according to an in-situ polymerization and spinning process, wherein the single-yarn fineness is 0.55-3.3 dtex, the breaking strength is 3.5-6.5 cN / dtex, and the elongation at break is 10-30%. The obtained temperature-adjustable filament has the advantages of intelligent temperature regulation and control and functional durability.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to an intelligent temperature-regulating filament and a preparation method thereof. Background technique [0002] With the advancement of science and technology, people are not limited to the basic needs of food and clothing. The demand for clothing comfort, lightness, warmth, and breathability is becoming more and more common. The need is even more urgent. [0003] The earliest temperature-regulating textiles are fabric textiles that add phase change materials (microcapsules) to viscose or acrylic (spun wool) fibers and then weave them. The phase change material (microcapsule) is generally coated with a substance with a melting point of 30-38°C and a crystallization temperature of 10-30°C in a micron-sized polymer capsule, and uses it to generate a solid-liquid / liquid-solid phase The time-varying heat absorption / radiation behavior makes the surroundings of the body a "microcircul...
