Problems solved by technology

[0002] In recent years, there have been more and more studies on the preparation of thermal insulation flakes by using various thermal insulation fibers. The commonly used thermal insulation fibers include hollow polyester fibers, non-metallic modified heat storage and thermal insulation fibers, and composite elastic fibers. There are also many researches, such as increasing flame retardancy, far-infrared properties, etc., but the effects cannot be combined, and there are many problems:
However, with mechanical action such as repeated compression during use, the hollowness of the hollow fiber is affected, and the amount of still air held is reduced, which in turn leads to a decrease in warmth retention.
[0004] 2. The existing hollow fibers and ultra-fine hollow fibers have good thermal insulation effects, but they cannot have both flame retardancy and far-infrared properties. Fibers that also have flame-retardant or far-infrared properties have poor thermal performance. Therefore, the traditional The flakes cannot have the functions of warmth retention, flame retardancy and far infrared emission at the same time

Abstract

The invention discloses far-infrared warm-keeping flame-retardant functional wadding and a preparation method thereof. The far-infrared warm-keeping flame-retardant functional wadding comprises a middle layer and far-infrared flame-retardant layers and is characterized in that the middle layer is formed by stacking multiple layers of composite warm-keeping layers, and the far-infrared flame-retardant layers are composited to the upper surface and the lower surface of the middle layer; each composite warm-keeping layer comprises a far-infrared layer, a warm-keeping layer and a framework layer which are sequentially stacked, and the far-infrared layer is made of far-infrared materials; the far-infrared flame-retardant layers are made of far-infrared materials and flame retardants. Experimentcomparison and analysis discovers that the thermal resistance of the far-infrared warm-keeping flame-retardant functional wadding is increased by 25-35% as compared with that of existing far-infraredwarm-keeping wadding, the far-infrared emission rate and far-infrared irradiation temperature rise of the far-infrared warm-keeping flame-retardant functional wadding are synchronously increased by about 30-35% as compared with those of the existing far-infrared warm-keeping wadding, the thermal resistance of the far-infrared warm-keeping flame-retardant functional wadding is increased by 28-38%as compared with that of existing flame-retardant warm-keeping wadding, and the after flame time of the far-infrared warm-keeping flame-retardant functional wadding is shortened by 20-28% as comparedwith that of the existing flame-retardant warm-keeping wadding.
