Problems solved by technology

However, down as a filler has always had the following problems: firstly, due to the shortage of raw materials, the supply and price of down are extremely unstable due to various factors, which has caused a lot of troubles in the preparation of materials for downstream enterprises. Problems such as microbial growth are also factors that limit its use
[0004] Although the above-mentioned prior art can improve the air content between the fibers to a certain extent and improve the heat retention, there are still many problems, such as the air between the fibers is not completely still, and there is still more air convection; Easy to be crushed, poor compression resilience, easy to become thinner after washing
So far, it is difficult to achieve the light weight and warmth effect of down

Abstract

The invention provides multi-dimensional warm-keeping cotton with a heat reflection function and a production method and application thereof, the multi-dimensional warm-keeping cotton with the heat reflection function is provided with at least two layers of structures, and the multi-dimensional warm-keeping cotton with the heat reflection function is formed by multi-component short fibers through a non-woven process; the outermost layer is a heat reflection thermal insulation layer comprising metal coating polyester, three-dimensional crimp polyimide and low-melting-point polyester, and the outermost layer is far away from a user; the innermost layer is a heat preservation layer comprising three-dimensional crimp polyimide, three-dimensional crimp acrylic fibers and low-melting-point polyester. The fibers with different components have different forms and corresponding functions, the fibers are distributed on different layers of the warm-keeping cotton through a non-woven process, the heat conductivity of each layer is different, and the metal coating polyester fibers are located on the outer layer and can reflect infrared rays of a human body and feed back heat lost by the human body, so that the reflective warm-keeping function is achieved. The warm-keeping cotton with the heat reflection function is excellent in heat preservation effect, relatively low in weight and capable of being applied to textiles.

Description

technical field [0001] The invention belongs to the technical field of textile preparation, and in particular relates to a multi-dimensional thermal insulation cotton with heat reflection function and its production method and application. Background technique [0002] At present, down is recognized as a material with good thermal insulation effect, which can save air to a great extent to prevent convection. And after washing and drying, the flexibility and elasticity of down itself can ensure its fluffiness recovery. However, down as a filler has always had the following problems: firstly, due to the shortage of raw materials, the supply and price of down are extremely unstable due to various factors, which has caused a lot of troubles in the preparation of materials for downstream enterprises. Problems such as microbial growth are also factors that limit its use. Therefore, research and development of fillings with the same warmth retention property as down has always be...
