Description

Technical Field

[0001] This utility model relates to the technical field of textile fabrics, and in particular to a lightweight and warm down fabric. Background Technology

[0002] With the rise of national fitness, more and more people are participating in sports. In order to experience comfort and freedom during exercise and feel weightless, consumers are demanding increasingly lighter and thinner clothing fabrics. However, in winter, lightweight fabrics, especially down fabrics, result in lower down content in down jackets, making them less warm.

[0003] In view of this, this utility model is developed by deeply conceiving and actively researching, improving and testing the design of the insulation structure of existing lightweight down jackets, which has caused many shortcomings and inconveniences. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of insufficient warmth retention in existing lightweight down jackets, and to provide a lightweight yet warm down fabric.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A lightweight and warm down fabric has a main fabric layer, which is made of warp and weft yarns in a plain weave pattern. Both the warp and weft yarns are made of 15D-30D nylon rare earth functional fiber yarns, with a warp density of 260T-295T and a weft density of 185T-210T.

[0007] Furthermore, the surface of the main fabric layer is also provided with a polyaliphatic compound film.

[0008] Furthermore, a calendering layer is provided on the reverse side of the main fabric layer.

[0009] Furthermore, the warp and weft yarns of the main fabric layer are FDY.

[0010] With the above structure, the main layer of the lightweight and warm down fabric of this invention is made of nylon rare earth functional fiber yarn. The rare earth elements in the yarn have abundant electronic energy levels and unique optical functional properties, enabling them to absorb and emit near-infrared wavelengths of 250nm-2500nm and far-infrared wavelengths of 5um-14um. Far-infrared thermal radiation of 5um-14um accounts for 60% of the heat loss from the human body. Rare earth materials can efficiently absorb the far-infrared energy radiated by the human body, raising the fabric temperature and forming a thermal cycle, thus reducing heat loss from the human body. Furthermore, rare earth elements can absorb high-intensity near-infrared light of 250nm-2500nm, such as sunlight and high-radiation lamp light, through localized surface plasma resonance, raising the fabric temperature and providing a noticeable feeling of warmth to the human body. Through the density design and weft pattern of the warp and weft yarns, the fabric structure is made compact. This compact structure effectively prevents down from escaping through the fabric gaps, resulting in a good hand feel and a down-proof effect without any lining. Therefore, this invention's fabric possesses the effects of being lightweight, warm, and down-proof. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the layer structure of this utility model.

[0012] Figure 2 This is an organizational diagram of the present invention. Detailed Implementation

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] like Figure 1 As shown, this utility model discloses a lightweight and warm down fabric, which is composed of three layers: upper, middle and lower.

[0015] The upper layer of the fabric is a polyaliphatic compound film 2, which serves as a water-repellent agent.

[0016] The middle layer of the fabric is the main fabric layer 2, such as... Figure 2 As shown, the main layer of the fabric is made of warp and weft yarns in a plain weave pattern, with both warp and weft yarns selected from 15D-30D nylon rare earth functional fiber yarns. These nylon rare earth functional fiber yarns are existing yarns, such as REbase Ebony Warmth. The yarn form is FDY (EW). To ensure that the fabric has a good hand feel and a non-pile-proof effect after calendering, the warp density is 260T-295T and the weft density is 185T-210T.

[0017] The warp and weft yarns of the main fabric layer of this utility model can be made of nylon rare earth functional fiber produced by China Textile Academy (Tianjin) Science and Technology Development Co., Ltd. (Ink Warmth) is made from rare earth elements, which possess abundant electronic energy levels and unique optical properties. These elements can absorb and emit near-infrared radiation with wavelengths of 250nm-2500nm and far-infrared radiation with wavelengths of 5um-14um. Far-infrared thermal radiation in the 5um-14um range accounts for 60% of the body's heat loss. Rare earth materials can efficiently absorb far-infrared energy radiated by the body, raising the fabric temperature and creating a thermal cycle that reduces heat loss. Furthermore, rare earth elements can absorb high-intensity near-infrared light (250nm-2500nm) from sunlight and high-radiation lamps through localized surface plasma resonance, raising the fabric temperature and providing a noticeable feeling of warmth.

[0018] The lower layer is the fabric calendering and downproof layer 3, which is formed by calendering on the reverse side of the main fabric layer to improve the fabric density and thus enhance the downproof effect of the fabric.

[0019] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
