Description

fabric structure

This work is about a fabric structure, especially a fabric structure with filling material.

In order to achieve better warmth retention effect in traditional cold clothing, the common practice is to increase the thickness of the fabric or fill the middle of the fabric with cotton or poultry feathers, down and other fillers, which are blocked by forming an air layer between the human skin and the outside world. The heat conduction between the human skin and the outside world, and then achieve the effect of keeping out the cold.

Traditionally, the better the cold weather, the heavier the clothing. For example, an adult coat made of animal fur can weigh several kilograms. However, for mountaineers or extreme sports at high altitudes With sufficient cold protection effect, the weight of the luggage on the body must also be strictly controlled. In the case of prolonged high-intensity activities, even a few grams of weight reduction can significantly reduce the total energy expended by the athlete. Therefore, if the weight of the clothes can be reduced on the premise of the same cold protection effect, it will be of great benefit to those engaged in mountaineering or extreme sports.

In order to reduce the weight of clothing, the focus is usually on reducing the thickness and weight of the filling material that provides thermal properties, and there are methods of changing the material of the filling material or using a composite material with added metal particles.

The conventional meltblown nonwoven can be used as a filling material. Meltblown nonwoven fabric is formed by meltblown method and has a dense structure. The melt blowing method uses a screw extruder to melt the high molecular polymer chips, spray the chips into spinning fibers through a spinneret hole, and then stretch them under a high-speed hot air flow to form extremely fine short fibers, which are then adsorbed. The short fibers are kept at high temperature to bond the fibers to each other, thereby forming a meltblown nonwoven fabric. Meltblown non-woven fabrics have excellent shielding properties, filtration properties, heat insulation properties and oil absorption properties due to their manufacturing method, and can also achieve water impermeability similar to plastic films after hot pressing.

For the method of adding metal particles to melt-blown non-woven fabrics, it is conventional to inject the molten fibers under the action of high-speed hot air flow, and then add metal particles near the nozzle, so that the metal particles are attached to the surface of the melt-blown fibers or enter into the pores of the fibers. . However, the adhesion between metal particles and meltblown fibers is extremely weak, and metal particles are prone to fall off.

In view of the above, this creation uses meltblown non-woven fabric as the base material, and attaches the fluffy filling material as a complete filling material. The effect of forming a vacuum layer and reflecting the heat radiation from the surface of the human body is achieved by the sandwiching of the melt-blown non-woven fabric and the metal layer, which can help to maintain a warm microclimate between the body and the filling material, and prevent the flowing air from entering. The temperature of the filling material is dissipated.

Specifically, the present creation provides a fabric structure, including: a first layer of cloth, a second layer of cloth, a filling material, an intermediate layer of cloth, and a metal layer. The second layer of cloth system is arranged on the surface of the first layer of cloth body and forms a closed accommodating space with the first layer of cloth body.
