Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, and in particular to a warm knitted fabric. Background Technology

[0002] With the development of technology and the improvement of people's living standards, comfort, functionality, and fashion have become the main considerations for clothing consumption, and people's requirements for the functionality of textiles are getting higher and higher. In autumn and winter, when temperatures are low, fabrics that combine heat retention, warmth, lightweight comfort, and softness have always been a core demand. Therefore, developing lightweight, soft, and warm fabrics that combine heat retention, warmth, and comfort has a very promising market prospect.

[0003] In the existing technology, most of the thermal knitted fabrics on the market are made by adding additives. Their function will gradually weaken with the increase of washing. In addition, the use of common thermal materials on the market results in insufficient fluffiness and heat retention performance of the fabric. Utility Model Content

[0004] The following is an overview of the subject matter described in detail herein, and this overview is not intended to limit the scope of the claims.

[0005] This invention proposes a thermal knitted fabric that can effectively block heat loss, significantly improve warmth retention, and also enhance the fabric's resistance to compression and deformation, making it less prone to collapse or deformation during use and extending its service life.

[0006] This utility model provides a warm knitted fabric, including a skin-friendly layer and a warm layer. The skin-friendly layer is woven with a weft plain knit structure. The warm layer includes a frame yarn layer and a warm yarn layer. The frame yarn layer and the warm yarn layer are interwoven to form the warm layer. The frame yarn layer is woven with solid yarn, and the warm yarn layer is woven with hollow yarn.

[0007] In some embodiments, the fabric of the skin-friendly layer is cotton yarn.

[0008] In some embodiments, the surface of the skin-friendly layer is formed with uniform fluff.

[0009] In some embodiments, the solid yarn and the hollow yarn alternately pass through different rows, which alternately include coil structures and float structures.

[0010] In some embodiments, monofilaments are arranged side by side around the hollow yarn, and the hollow yarn and the monofilaments are woven side by side.

[0011] In some embodiments, the fabric of the frame yarn layer is solid polyester.

[0012] In some embodiments, the fabric of the insulating yarn layer is hollow polyester.

[0013] In some embodiments, the hollow polyester has an irregular elliptical cross-section.

[0014] This invention offers at least the following advantages: By using a weft-knit weave to sew the skin-friendly layer, the fabric's front side is smooth and its back side is flat, allowing it to conform to human skin, reducing friction and discomfort, and providing a comfortable wearing experience. The insulating layer consists of a frame yarn layer and an insulating yarn layer. The frame yarn layer is woven with solid yarn, providing a stable support structure. The insulating yarn layer is woven with hollow yarn; the hollow structure can accommodate more still air, and since air is a poor conductor of heat, it effectively blocks heat loss, significantly improving insulation performance. The hollow yarn also reduces the fabric's weight, making it lighter. The interlaced weave between the frame yarn layer and the insulating yarn layer gives the fabric good softness and elasticity, making it more comfortable and free to wear. This creates a well-integrated three-dimensional structure for the insulating layer, which not only enhances the fabric's thickness and bulkiness but also improves its compressive strength and deformation resistance, making it less prone to collapse or deformation during use and extending its service life.

[0015] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description, claims, and drawings.

[0022] Currently, most thermal knitted fabrics on the market use additives, and their thermal insulation effect gradually weakens with each wash. Furthermore, because they use common thermal insulation materials, the fabric's fluffiness and heat retention performance are not significant enough.

[0023] To address the problem of poor heat retention, this invention provides a heat-retaining knitted fabric that effectively blocks heat loss, significantly improves heat retention, and also enhances the fabric's resistance to compression and deformation, making it less prone to collapse or deformation during use and extending its service life.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 This utility model provides a warm knitted fabric, characterized in that it includes a skin-friendly layer 100 and a warm layer 200. The skin-friendly layer 100 has a weft plain knit structure. The warm layer 200 includes a frame yarn layer 210 and a warm yarn layer 220. The frame yarn layer 210 and the warm yarn layer 220 are interwoven to form the warm layer 200. The frame yarn layer 210 is woven from solid yarn, and the warm yarn layer 220 is woven from hollow yarn.

[0026] Understandably, the skin-friendly layer 100 uses a plain weave structure, which is tight and flat, making the front and back of the fabric smooth and conforming to the human skin, reducing friction and discomfort, and providing a comfortable wearing experience. The insulating layer 200 consists of a frame yarn layer 210 and an insulating yarn layer 220. The frame yarn layer 210 is woven with solid yarn, providing a stable support structure. The insulating yarn layer 220 is woven with hollow yarn. The hollow structure can accommodate more still air, and since air is a poor conductor of heat, it effectively blocks heat loss, significantly improving the insulation performance. The hollow yarn also reduces the weight of the fabric, making it lighter. The interlaced weave between the frame yarn layer 210 and the insulating yarn layer 220 also gives the fabric good softness and elasticity, making it more comfortable and free to wear. This creates a well-integrated three-dimensional structure for the insulating layer 200, which not only enhances the thickness and bulk of the fabric but also improves its compressive strength and deformation resistance, making it less prone to collapse or deformation during use and extending its service life.

[0027] In some embodiments of this utility model, the fabric of the skin-friendly layer 100 is cotton yarn, the surface of the skin-friendly layer 100 is covered with uniform fluff, the fabric of the frame yarn layer 210 is solid polyester, and the fabric of the thermal insulation yarn layer 220 is hollow polyester.

[0028] The Skin-Friendly Layer 100 fabric is made of cotton yarn. Cotton fibers have excellent moisture absorption and breathability, effectively absorbing moisture from the skin's surface to keep it dry and reduce dampness and odor. At the same time, cotton yarn is soft and non-irritating, making it very friendly to people with sensitive skin and effectively reducing the risk of allergies or discomfort. The uniform nap formed on the surface of the Skin-Friendly Layer 100 enhances the fabric's softness and comfort, while increasing the air layer between the fabric and the skin, providing extra warmth and making the fabric fit the skin more closely, reducing friction and discomfort.

[0029] The skin-friendly layer 100 uses a fleece-grabbing machine to grab, comb, cut, and fleece the fabric base. Due to the improvement of the fleece-grabbing process, the fleece effect of the fabric base is more delicate, the fabric is more fluffy and warm, and it is not easy to shed.

[0030] The frame yarn layer 210 is woven from solid polyester fibers. Solid polyester fibers have high strength and stability, providing a robust support structure for the insulation layer 200. This ensures that the shape and thickness of the insulation layer 200 are maintained, preventing it from being flattened or deformed during use, thus extending the durability of the insulation effect. The insulation yarn layer 220 is woven from hollow polyester fibers. The hollow structure inside the hollow polyester fibers can hold more still air. Since air is a poor conductor of heat, this structure can effectively reduce heat loss, significantly improving the fabric's insulation performance. At the same time, the high loft of the hollow polyester fibers makes the fabric lighter and softer, further enhancing wearing comfort.

[0031] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the weave structure of the skin-friendly layer 100. Figure 2 This is a schematic diagram of the knitting structure of the insulation layer 200. The skin-friendly layer 100 adopts a plain weft knitting structure, with the reverse side of the plain weft knitting structure facing the human skin. The insulation layer 200 is a quilted structure as a whole. The insulation layer 200 includes a total of loop structures and float structures. The loop structures and float structures appear alternately on the same row. The solid knitting yarn and the hollow knitting yarn alternately pass through different rows. The rows alternately include loop structures and float structures.

[0032] In one specific embodiment, solid yarns on one row extend interlaced into adjacent rows, while solid yarns on adjacent rows extend into other adjacent rows. This creates a well-integrated three-dimensional structure in the fabric, which not only enhances the thickness and bulkiness of the insulation layer 200 but also improves the fabric's resistance to compression and deformation, making it less prone to collapse or deformation during use.

[0033] In addition, in some embodiments of this utility model, the hollow yarn is surrounded by monofilaments, and the hollow yarn and the monofilaments are woven side by side, with the fabric of the monofilaments being ultra-fine polyester yarn.

[0034] The monofilaments are woven side-by-side around the hollow yarn, providing additional structural support and making the fabric stronger and less prone to deformation. The ultra-fine polyester yarn has high strength and abrasion resistance, effectively resisting external friction and tensile forces, extending the fabric's lifespan. The combination of hollow yarn and monofilaments improves the compressive strength of the 220 insulating yarn layer, making it less prone to flattening under external pressure, thus maintaining good warmth retention and bulkiness.

[0035] The cotton yarn in the skin-friendly layer 100 consists of 32-count cotton yarn per strand; the solid polyester in the frame yarn layer 210 is composed of 36 single fibers with a linear density of 75 denier; the hollow polyester in the thermal insulation yarn layer 220 is composed of 96 polyester fibers with a linear density of 150 denier; and the monofilament yarn is composed of 144 polyester fibers with a linear density of 150 denier.

[0036] In addition, in some embodiments of this utility model, the cross-section of the hollow polyester is an irregular ellipse.

[0037] The irregular hollow structure increases the fiber's bulkiness, making the fabric soft and full to the touch, thus enhancing wearing comfort. Furthermore, the irregular hollow structure provides excellent resilience, making it less prone to deformation. Even under external pressure, it quickly returns to its original shape, maintaining the shape and appearance of the insulation layer 200.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
