Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a heat-sensitive woven fabric. Background Technology

[0002] As the name suggests, heat-sensitive fabrics are fabrics that can generate heat. The main reason they can generate heat is the heat-sensitive fibers inside.

[0003] Thermosensitive fiber is not a completely new fiber material, but a functional composite fiber made through a special process. Thermosensitive fiber usually chooses polyester as the base material because polyester's melt spinning technology is very mature, and its physical properties are stable and its strength is high, making it suitable as a carrier for functional additives. During the polyester spinning process, nano-sized metal oxide ceramic powder is incorporated. After absorbing heat from the human body, the ceramic powder emits far-infrared rays that act on the human body, producing a warming effect and achieving the fabric's heat-sensitive effect. However, the base material of thermosensitive fiber is polyester, which is a hydrophobic fiber with weak moisture absorption, making it easy for sweat to remain between the fabric and the skin. Since thermosensitive fiber also generates heat, the combination of heat and moisture can easily cause a stuffy feeling.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat-sensitive woven fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat-sensitive woven fabric, including a base layer, the base layer being woven from base yarn and moisture-absorbing yarn, the diameter of the moisture-absorbing yarn being larger than the diameter of the base yarn, the base layer having protrusions and concave portions, the protrusions being formed by the interlacing of warp and weft moisture-absorbing yarns, the concave portions being formed by the interlacing of warp and weft base yarns, the concave portions being rectangular in shape, and the four corners of the concave portions being supported by the protrusions; The base yarn includes a core yarn and a winding yarn wrapped around the core yarn. The winding yarn includes a heat-sensitive yarn and a support yarn. The diameter of the support yarn is larger than that of the heat-sensitive yarn. The core yarn is made of heat-sensitive yarn wound together. The heat-sensitive yarn is made of heat-sensitive fibers twisted together. The support yarn is made of viscose fibers twisted together.

[0007] The present invention is further configured such that: a heat-insulating yarn interwoven with the warp and weft of the concave portion passes through the base layer.

[0008] The present invention is further configured such that: the thermal insulation yarn is made of natural fibers twisted together, the ratio of the amount of thermal insulation yarn in the concave part to the amount of base yarn is 1:4, and the surface of the thermal insulation yarn has fuzz.

[0009] The present invention is further configured such that the thermal yarn is made of twisted cashmere fibers.

[0010] The present invention is further configured such that the moisture-absorbing yarn is made of twisted wool fibers.

[0011] The present invention is further configured such that the distance between the yarns located in the convex portion is greater than the distance between the yarns located in the concave portion.

[0012] In summary, this utility model has the following beneficial effects: The convex parts protrude from the base layer, while the concave parts are recessed into the base layer. This concentrates most of the area in contact with the body surface on the convex parts, while there is a gap between the concave parts and the body surface. The concave parts are the main areas of heat release from the base layer. By setting the gap, airflow over the body surface can be increased, thereby reducing the feeling of stuffiness. The moisture-absorbing yarn has excellent moisture-absorbing properties and can absorb moisture from the body surface, thereby reducing the impact of humidity on human comfort and thus helping to reduce people's feeling of stuffiness.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Heat-sensitive woven fabrics, such as Figure 1 and Figure 2As shown, the substrate includes a base layer woven from base yarn 1 and moisture-absorbing yarn 2. The diameter of the moisture-absorbing yarn 2 is larger than that of the base yarn 1, and is at least twice the diameter of the base yarn 1. Both the base yarn 1 and the moisture-absorbing yarn 2 have yarns arranged in the warp and weft directions towards the substrate. The substrate has protrusions 3 and concave portions 4. The protrusions 3 are formed by the interlacing of the warp and weft moisture-absorbing yarns 2, and the concave portions 4 are formed by the interlacing of the warp and weft base yarns 1. The concave portions 4 are rectangular in shape, and their four corners are supported by the protrusions 3. This arrangement makes the concave portions 4 less prone to collapse. The protrusions 3 are also rectangular, but their area is smaller than that of the concave portions 4. The protrusions 3 protrude from the substrate, while the concave portions 4 are recessed into the substrate. This concentrates most of the area in contact with the body surface on the protrusions 3, while a gap exists between the concave portions 4 and the body surface. The recessed portion 4 is the main area for heat release in the base layer. By setting gaps, airflow over the body surface can be increased, thereby reducing stuffiness. The moisture-absorbing yarn 2 has excellent moisture-absorbing properties and can absorb moisture from the body surface, thereby reducing the impact of humidity on human comfort and helping to reduce stuffiness. The distance between the yarns in the convex portion 3 is greater than that in the recessed portion 4. The convex portion 3 is looser, which improves its softness, and the spacing facilitates the rapid evaporation of absorbed sweat. The recessed portion 4 is tighter. The smaller spacing means a denser fabric structure, which helps to lock in heat and reduce heat loss. In addition, the smaller yarn spacing means more interlacing points and stronger cohesion between yarns, which results in a thinner fabric in this area, making the recessed portion 4 more obvious.

[0017] like Figure 1 and Figure 2As shown, the base yarn 1 includes a yarn core and a winding yarn wrapped around the yarn core. The winding yarn includes a heat-sensitive yarn 5 and a support yarn 6. The diameter of the support yarn 6 is larger than that of the heat-sensitive yarn 5. The yarn core is made of the heat-sensitive yarn 5, which is twisted from heat-sensitive fibers. The support yarn 6 is twisted from viscose fibers. The support yarn 6 forms a protrusion on the surface of the base yarn 1, thereby reducing the contact area between the heat-sensitive yarn 5 and the body surface. The viscose fibers have a certain degree of hygroscopicity, which can assist the moisture-absorbing yarn 2 in absorbing moisture. At the same time, the viscose fibers can also provide comfort and drape, improving the comfort of the recess 4. The heat-sensitive fibers can generate a heat-sensitive effect, thus ensuring the overall heat-sensitive effect of the base layer. A thermal insulation yarn 7, which is interwoven with the warp and weft of the recess 4, also passes through the base layer. The thermal insulation yarn 7 has a heat-insulating effect, improving the heat-insulating effect of the recess 4, so that the heat from the heat-sensitive fibers acting on the body surface can be better absorbed. For storage, the thermal yarn 7 is made of twisted natural fibers. The ratio of thermal yarn 7 to base yarn 1 in the concave part 4 is 1:4. The surface of thermal yarn 7 has fuzz. Natural fibers have good breathability, allowing the concave part 4 to have some ventilation through the woven space of thermal yarn 7. The fuzz provides some support to the concave part 4, ensuring the distance between the concave part 4 and the body surface and reducing the feeling of the base layer sticking together. The thermal yarn 7 is made of twisted cashmere fibers. Cashmere fibers have good warmth retention and are lightweight and soft. The surface of the cashmere yarn has natural fuzz, which also has good softness and comfort. The moisture-absorbing yarn 2 is made of twisted wool fibers. Wool fibers have good moisture absorption and breathability, as well as good warmth retention. It ensures the moisture absorption performance of the convex part 3 while also taking into account the warmth retention and breathability of the convex part 3.
