Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitted fabric technology, and more specifically, to a heat-retaining knitted fabric. Background Technology
[0002] Clothing is made of knitted fabric, and the characteristics of knitted fabric not only interpret the style of clothing, but also directly affect the wearing experience.
[0003] Chinese utility model patent with announcement number CN219381824U introduces a graphene intelligent heat-storing knitted fabric, including a heat-storing fabric layer and multiple graphene heating elements. The heat-storing fabric layer is a heat-storing knitted double-layer fabric, which consists of three horizontal rows forming a weave loop. The first horizontal row is the front coil, the second horizontal row is the back coil, and the first and second horizontal rows are connected by the loop weave of the third horizontal row. Multiple graphene heating elements are printed on one side of the heat-storing fabric layer.
[0004] The problem addressed by the above solution is that graphene and intelligent heat storage finishing agent have different mechanisms of action. Graphene plays a role in far-infrared heating, while intelligent heat storage finishing agent plays a role in intelligent heat storage. Currently, there are graphene far-infrared products and heat storage and insulation products on the market, but products that combine both functions are rare.
[0005] This application provides another technical solution to this technical problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat-retaining knitted fabric.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0008] A heat-storing knitted fabric includes an abrasion-resistant layer, an intermediate layer, and a contact layer. The contact layer is formed into a pile through a napping process. The abrasion-resistant layer has several perforations. Several recesses are formed on both sides of the intermediate layer. The portion of the intermediate layer facing the abrasion-resistant layer has a corresponding perforation. The intermediate layer and the contact layer are combined at the corresponding perforations to form several static air cavities. The intermediate layer is woven from far-infrared yarn.
[0009] The present invention is further configured such that a light-transmitting silicone strip is bonded and fixed to the recess on the side of the intermediate layer facing the wear-resistant layer, and the light-transmitting silicone strip is in contact with the wear-resistant layer.
[0010] The present invention is further configured such that the cross-sectional size of the recess is larger than the cross-sectional size of the perforation.
[0011] The present invention is further configured such that an aluminum foil layer is bonded and fixed to the bottom of the recess on the side of the intermediate layer facing the contact layer.
[0012] The present invention is further configured such that: the wear-resistant layer is woven from wear-resistant yarn in a perforated structure, and the wear-resistant yarn is polyester yarn.
[0013] The present invention is further configured such that the polyester yarn is 50D / 288F.
[0014] In summary, this utility model has the following beneficial effects:
[0015] Sunlight shines through the perforations and translucent silicone strips onto the middle layer. The far-infrared yarn absorbs the sunlight's energy and releases it towards the body. At the same time, the far-infrared yarn accumulates the body's heat and then releases it back to the body, thus improving the overall warmth of the knitted fabric.
[0016] The still air inside the still air cavity, along with the aluminum foil layer, provides insulation, reducing heat loss from the body and improving warmth retention. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figure 1 As shown, this application provides a heat-retaining knitted fabric, including an abrasion-resistant layer 1, an intermediate layer 2, and a contact layer 3. The abrasion-resistant layer 1, the intermediate layer 2, and the contact layer 3 are bonded together by TPU hot melt adhesive. TPU hot melt adhesive has good adhesion and breathability, which can improve the breathability and comfort of the knitted fabric. The contact layer 3 is woven from acrylic yarn and is also napped so that the contact layer 3 is far away from the intermediate layer 2 to form a pile 4. By utilizing the characteristics of acrylic yarn and pile 4, the warmth retention effect of the knitted fabric can be improved.
[0021] like Figure 1 As shown, the intermediate layer 2 is woven from far-infrared yarn, which is made by twisting multiple strands of acrylic fiber. During the spinning process, far-infrared ceramic powder is added to the spinning solution to give the acrylic fiber a far-infrared effect. After the intermediate layer 2 is completed, it is heat-set to create several recesses 5 on both sides of the intermediate layer 2. The recesses 5 are spaced apart. After the intermediate layer 2 is laminated, the intermediate layer 2 and the contact layer 3 are combined at the corresponding perforations 9 to form several static air cavities 6. The static air cavities 6 contain static air. At the same time, an aluminum foil layer 7 is bonded and fixed to the bottom of the recesses 5 on the side of the intermediate layer 2 facing the contact layer 3. Both the static air and the aluminum foil layer 7 can provide heat insulation, thereby increasing the warmth of the knitted fabric.
[0022] like Figure 1 As shown, the wear-resistant layer 1 is woven from wear-resistant yarn, which is made of polyester yarn. In this embodiment, the polyester yarn is 50D / 288F. Polyester yarn has the characteristics of high strength and wear resistance, which can improve the service life. The wear-resistant layer 1 will form a number of perforations 9. The recesses 5 of the middle layer 2 facing the wear-resistant layer 1 correspond to the perforations 9. Before the middle layer 2 and the wear-resistant layer 1 are laminated, transparent silicone is squeezed into the recesses 5 of the middle layer 2 facing the wear-resistant layer 1, so that a light-transmitting silicone strip 8 is bonded in the recesses 5. After the middle layer 2 and the wear-resistant layer 1 are laminated, the light-transmitting silicone strip 8 is in contact with the wear-resistant layer 1. The light-transmitting silicone strip 8 can prevent foreign objects or cold air from entering the recesses 5 through the perforations 9.
[0023] After sunlight passes through the perforations 9 and the translucent silicone strips 8, it shines on the middle layer 2. The far-infrared yarn absorbs the energy of the sunlight and releases it towards the body. At the same time, the far-infrared yarn accumulates the heat emitted from the body by the contact layer 3 and then releases it to the body, thereby improving the overall warmth of the knitted fabric.
[0024] In summary, the knitted fabric provided in this embodiment can improve the warmth retention effect of the knitted fabric by absorbing and conducting sunlight energy and reflecting body energy.
[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
