Coffee is not a stranger. In addition to being able to drink, we often put coffee grounds into an ashtray, which can remove the smell of smoke and easily extinguish cigarette butts. Now the residual value of coffee grounds has been added: using coffee grounds to absorb odor, dehumidification and sweat quickly and can be recycled, the recycling of coffee grounds. Using coffee grounds as raw material, the coffee grounds are calcined at high temperature to make the crystal of coffee grounds present the best state to the pores. Using special technology to produce coffee carbon fiber, through the alliance of industrial chain, the development of coffee carbon fiber products. The coffee grounds have become environmentally friendly materials for textiles. Firstly, coffee toner suitable for spinning and with specific functions was selected to make use of discarded coffee grounds. After calcination above 1000 ℃, the crystal orientation and pores of coffee grounds are in the best condition.
Coffee carbon fiber using the latest nanotechnology, micro-pulverization, grinding into 100-300 nanometer powder, followed by the special process of processing into the use of fiber production masterbatch, the study of the appropriate spinning and drafting process. To ensure the spinnability of the products in the post-processing plant, at the same time, special spinneret is designed to solve the drying problem. Spinning and drafting and other key production processes. The suitable content of coffee carbon in fiber was tested and determined. Finally, a certain content of masterbatch and polyester chip blend was optimized and determined to ensure the appropriate content of powder in the fiber.
Characteristics of coffee carbon fiber
1. Environmental protection: reduce carbon footprint, its carbon emissions are 48% lower than bamboo carbon and 85% lower than coconut carbon.
2. Warmth retention: After testing, coffee carbon fiber has a higher temperature rise than ordinary PET fiber under light irradiation. Wearing coffee carbon clothing can enjoy the natural and warm comfort brought by coffee.
3. Antibacterial and deodorizing: Water and nutrients are the hotbed of bacteria. The speed of bacterial reproduction depends on how much temperature, water and nutrients the environment can provide. The porous adsorption effect of coffee carbon allows effective control of body surface water and inhibits bacterial reproduction. . The odorous ammonia released when bacteria multiply is also greatly reduced, so coffee carbon can also effectively deodorize.
4. Emit negative ions: Coffee carbon fiber can also emit negative ions. Studies have confirmed that "oxygen free radicals" have chronic adverse effects on health, not only causing cell aging, destroying proteins, but also reducing immunity, accelerating arteriosclerosis and carcinogenesis. The main function of negative ions is to neutralize "oxygen free radicals" and slow down cell oxidation. Studies have shown that the negative ions absorbed by wearing coffee carbon products are the same as walking in the park in the morning, about 400-800 per cubic centimeter, which is 2-4 times that of an office and 6-8 times that of outdoor traffic.
Clothing made of coffee carbon fiber is not only natural and environmentally friendly, but also has many functions, such as far infrared ray, negative ion, heat storage and warmth. It is very suitable for weaving close-fitting clothing. The function of coffee carbon fiber is permanent and is not affected by the number of washing times.
