Embodiment 1-3

[0030] Embodiment 1-3: A manufacturing process for heat storage and heat preservation cotton, the heat storage and heat preservation cotton is obtained through the following process, which process includes the following steps:

[0031] Step 1, heating the fibers of the coconut shell to 480-520°C for carbonization treatment to obtain carbonized fibers, the carbonization temperature is 480°C in Example 1, 500°C in Example 1, and 520°C in Example 1; then carbonize Coconut carbon micropowder is obtained by high-temperature activation treatment at 800-1000°C on fiber, which can produce activated carbon with developed microporous structure and huge specific surface area. , embodiment 1 is 800 ℃;

[0032] Step 2, the polyester chip, silane coupling agent, zinc stearate as surfactant and liquid wax as dispersant are uniformly mixed at high temperature according to the mass ratio of 100:0.39~0.41:2.7~2.8:6.8~7 Form molten polyester; zinc stearate: surfactant, reduce the surface tensio...

Abstract

The invention discloses a manufacturing process for heat storage insulation cotton, which includes the steps: heating fibers of a coconut shell to a certain degree to generate coconut carbon micro-powder; evenly mixing polyester chips, silane coupling agents, zinc stearate and liquid wax to form melted polyester; evenly mixing the coconut carbon micro-powder and the melted polyester according to the mass ratio of 1:3.8-4.2 to form mixture; weaving the mixture into coconut carbon micro-powder master batches through a granulator; evenly mixing the coconut carbon micro-powder master batches with the polyester chips according to the mass ratio of 1: 8.5-9.5 to form coconut carbon fiber yarns by means of melting and spinning; stretching the coconut carbon fiber yarns to form coconut carbon fiber filaments; cutting the coconut carbon fiber filaments into a plurality of 5-7cm coconut carbon staple fibers; and manufacturing the coconut carbon staple fibers into insulation cotton by a non-weaving process. The heat storage insulation cotton obtained by the manufacturing process has adsorptivity and is fast in temperature rise, high in temperature, high in heat storage capacity and long in insulation time, and air permeability of the heat storage insulation cotton is greatly improved.

Description

technical field [0001] The invention relates to a manufacturing process for heat storage and heat preservation cotton, which belongs to the technical field of textile fabrics. Background technique [0002] At present, the insulation cotton on the market is made of natural fibers and synthetic fibers, and the processing technology is also various, such as acupuncture, spunlace, thermal bonding and so on. On the one hand, such products are either too thin and have poor thermal insulation performance, or they are too heavy, and energy conservation is a basic national policy of our country. It is a basic measure of our country to vigorously promote energy conservation, save resources, and implement sustainable development. On the other hand, the existing thermal insulation cotton greatly sacrifices its air permeability, which is not conducive to the further improvement of thermal performance and long-term thermal insulation. [0003] With the emergence of industry, human beings...
