Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to a high heat storage and warmth-keeping polyester fabric. Background Art

[0002] Polyester fabric is a kind of chemical fiber clothing fabric used very much in daily life. Its biggest advantage is its good wrinkle resistance and shape retention, so it is suitable for outdoor products such as outerwear.

[0003] However, the current outdoor cold-proof thermal clothing has a less than ideal cold-proof effect and cannot provide real warmth. First, the far-infrared emissivity of ordinary fabrics is only 0-0.3, and the temperature rise is 0-0.5 degrees. The conventional improvement method is: in the post-finishing process, add far-infrared additives, whose far-infrared emissivity is 1.2, and the far-infrared radiation temperature rise is about 2.5 degrees, which improves the warmth effect, but the effect deteriorates after repeated washing; or change the warp and weft yarns into far-infrared yarns, which have a more lasting effect than the far-infrared additives, and the temperature rise can reach about 2.5 degrees, but the cost is high, the fabric needs to be custom-woven, and the cycle is very long.

[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0016] Embodiment 1, as Figure 1-2 As shown, a high heat storage and thermal insulation polyester fabric includes a polyester pongee fabric base layer 1, a graphene hot stamping layer 2 is fixedly bonded to the upper surface of the polyester pongee fabric base layer 1 by melt adhesive, and an aerogel film 3 is fixedly bonded to the lower surface of the polyester pongee fabric base layer 1; the graphene hot stamping layer 2 and the aerogel film 3 are completely covered on the upper surface and the lower surface of the polyester pongee fabric base layer 1 respectively.

[0017] Among them, the base layer 1 of the polyester pongee fabric is made of 300T polyester pongee fabric with a warp density of 75 shuttles and a weft density of 43 shuttles, which is interwoven by warp and weft threads. The warp and weft of the polyester pongee fabric base layer 1 are both interwoven with DTY50D / 72F polyester filaments, and the fabric is woven with a flat variable texture.

[0018] The graphene hot stamping layer 2 includes a hot stamping layer 21, a graphene layer 22 and an anti-radiation layer 23. The graphene layer 22 is fixedly bonded to the upper surface of the polyester pongee fabric base layer 1 by melt adhesive, the anti-radiation layer 23 is fixedly bonded to the upper surface of the graphene layer 22, and the hot stamping layer 21 is fixedly bonded to the upper surface of the anti-radiation layer 23.

[0019] Working principle:

[0020] Firstly, the weaving method is adopted. The warp and weft yarns are both made of 50D / 48F polyester long fibers. The warp yarn density is 75 shuttles and the weft yarn density is 43 shuttles. 300T polyester pongee fabric is used as the base layer 1 of polyester pongee fabric. The plain weave has smaller gaps between yarns than the knitted weave. The density of 300T makes it difficult for heat energy to escape from the fiber gaps.

[0021] Then, the graphene hot stamping layer 2 is fixedly bonded to the upper surface of the polyester pongee fabric base 1 by melt adhesive, and the aerogel film 3 is fixedly bonded to the lower surface of the polyester pongee fabric base 1. The graphene hot stamping layer 2 absorbs far-infrared rays and converts them into heat to stay in the carrier fabric. Its far-infrared emissivity is 1.3, and the far-infrared radiation temperature rise is 3.5 degrees, thereby effectively achieving a warming effect; and the aerogel film 3 makes the air microporous, so that the temperature can be firmly locked. Thus, a long-term thermal insulation effect is achieved. Then, the warmth retention problem of outdoor cold-proof fabrics is greatly improved.

[0022] In addition, because the graphene hot stamping layer 2 and the aerogel film 3 are bonded by melt adhesive and completely cover the upper and lower surfaces of the polyester pongee fabric base 1, the fabric is heated by conventional far-infrared additives, and the washability is greatly improved. And the process of fabric from weaving to dyeing and then applying additives is reduced.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
