Description

Technical Field

[0001] The present invention relates to the technical field of heat-insulating knitted fabrics, and specifically to an aramid and seaweed fiber composite high heat-insulating knitted fabric and its processing technology. Background Technique

[0002] The main functions of heat-insulating knitted fabrics are heat insulation and warmth retention. Through special structural design, such fabrics can, to a certain extent, block the direct influence of external temperature on the human body, thus playing the role of heat preservation and insulation. Specifically, heat-insulating knitted fabrics usually have a multi-layer structure, including an antibacterial layer, a heat-insulating layer, a knitted polyester layer, a moisture absorption and sweat discharge layer, a cooling layer, etc. Seaweed fiber has good moisture absorption and air permeability and certain antibacterial properties, but it is not resistant to acid and alkali, has low wet strength, and poor fiber cohesion, which limits its application in the clothing field; aramid has good mechanical properties and excellent heat-insulating performance, but poor moisture absorption and air permeability. Both seaweed fiber and aramid are new functional materials with natural flame-retardant properties. Seaweed fiber is environmentally degradable, comfortable, moisture-absorbing, breathable, and has good skin-friendly functions. Aramid is a new type of high-tech synthetic fiber. Therefore, most current heat-insulating knitted fabrics are composed of a composite of aramid and seaweed fiber. They have excellent heat-insulating performance and are supplemented with aramid and seaweed fiber composite functional knitted fabrics with moisture absorption and antibacterial functions. The mechanical properties, moisture absorption properties, and thermal conductivity of the fabric are tested. The results show that the aramid and seaweed fiber composite knitted fabric has good mechanical properties, moisture absorption and air permeability, and high heat-insulating characteristics, and is suitable for the development of heat-insulating knitted fabrics for firefighters' clothing.

[0003] However, traditional heat-insulating knitted fabrics have the following disadvantages:

[0004] Traditional heat-insulating knitted fabrics have poor self-elasticity, which is not conducive to wearers making large movements. After being pulled, the heat-insulating knitted fabric deforms and cannot be restored, affecting the subsequent use of the heat-insulating knitted fabric. Summary of the Invention
