Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, and more specifically, to warm knitted fabrics. Background Art

[0002] Knitted fabrics are formed by connecting several coils together longitudinally or transversely. Each coil has to go through the looping process of the knitting needle to complete the weaving. It is a common type of fabric used to make clothing.

[0003] In order to ensure the warmth retention of clothing fabrics, the thickness of the fabrics is often increased during production to reduce the amount of cold air that passes through the fabrics and contacts the user's body surface. However, thick clothing is not soft and fluffy enough, which causes inconvenience in movement when people are wearing heavy clothing. Therefore, a structure is provided to solve the problem of thick thermal insulation fabrics. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a warm knitted fabric, which can improve the overall thermal insulation performance of the fabric through structural settings.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: the warm knitted fabric includes an inner layer and an outer layer fixedly connected to each other, and a plurality of warming sheets that are against the inner layer are fixedly connected to the side of the outer layer close to the inner layer, and a plurality of accommodating grooves with the same relative position as the warming sheets are opened on the side of the inner layer close to the outer layer, and the depth of the accommodating grooves is two-thirds of the thickness of the inner layer.

[0006] The utility model is further configured as follows: a plurality of warm fleeces are integrally formed on both sides of the inner layer, and the warm fleece includes a plurality of wool fibers.

[0007] The utility model is further configured as follows: a plurality of reinforcing fleeces are integrally formed on one side of the thermal insulation sheet close to the inner layer, and the reinforcing fleeces are configured as a plurality of nylon shaped fibers with a hollow circular cross-section.

[0008] The utility model is further configured as follows: the inner layer is woven by warm-keeping yarns, and the warm-keeping yarns include a warm-keeping yarn core and a warm-keeping covering yarn spirally wound on the outer side thereof.

[0009] The utility model is further configured as follows: the thermal insulation yarn core is formed by twisting nylon fibers, and the thermal insulation covering yarn is formed by twisting graphene fibers.

[0010] The utility model is further configured as follows: the outer layer is woven by composite yarns, and the composite yarns include composite yarn cores and composite covering yarns.

[0011] The utility model is further configured as follows: the composite yarn core is formed by twisting wool fibers, and the composite covering yarn is formed by double twisting nylon fibers.

[0012] To sum up, the utility model has the following beneficial effects: through the provision of the thermal insulation sheet, a channel for retaining external static air is formed between the inner layer and the outer layer, and the side walls of the channel are closed, thereby reducing the outflow of air in the channel, and the thermal conductivity of the air is poor, thereby ensuring the warmth of the fabric, and the thermal insulation sheet has good elasticity, so that the fabric can be reset under the action of its own elastic deformation properties after the pressure on the fabric disappears, thereby ensuring the fluffy effect of the structure.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The warm knitted fabric, such as Figure 1 and Figure 2 As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other. The inner layer 1 and the outer layer 2 are sewn together by a sewing machine. The setting of the double-layer fabric increases the thickness of the fabric, reduces the speed of exchange between body heat and external cold air, and ensures the warmth retention of the fabric. The outer layer 2 is sewn with a plurality of thermal insulation sheets 3 against the inner layer 1 on one side close to the inner layer 1 by a sewing machine. The setting of the thermal insulation sheets 3 allows a space for external static air to remain between the inner layer 1 and the outer layer 2. The thermal conductivity of the air is poor, thereby ensuring the lightness and warmth retention of the overall structure. The thermal insulation sheets 3 have good elasticity, so that the fabric can be restored under the action of its own elastic deformation properties after the external pressure disappears, thereby ensuring the fluffy effect of the fabric.

[0021] like Figure 1 and Figure 2 As shown, a plurality of receiving grooves 4 having the same relative position as the thermal insulation sheet 3 are formed on one side of the inner layer 1 close to the outer layer 2 by hot pressing using a hot press, and the depth of the receiving grooves 4 is two-thirds of the thickness of the inner layer 1. The air content between the thermal insulation sheet 3 and the inner layer 1 is increased by setting the depth of the receiving grooves 4, and the fabric after hot pressing will melt the fibers inside the fabric and seal the pores inside the fabric, thereby reducing the air retained in the receiving grooves 4 from flowing out of the receiving grooves 4, thereby enhancing the thermal insulation of the structure, and the setting of the receiving grooves 4 reduces the thickness of the inner layer 1, so that the fabric can be better deformed under the action of the receiving grooves 4 during use, so that the fabric can have a certain fluffy effect while ensuring thermal insulation performance.

[0022] like Figure 1 and Figure 3 As shown, a plurality of thermal fleece 5 are integrally formed on both sides of the inner layer 1, and the thermal fleece 5 includes a plurality of wool fibers. The inner layer 1 is configured as a plush tissue, so that the thermal fleece 5 can be naturally formed on the surface of the inner layer 1 during production. The configuration of the thermal fleece 5 increases the thickness of the inner layer 1, so that the inner layer 1 can better block the cold air entering the inside of the fabric, and the space for the outside air to be retained on the inner layer 1 is increased by the configuration of the thermal fleece 5, thereby enhancing the overall warmth retention of the fabric by increasing the amount of air inside the fabric.

[0023] like Figure 1 and Figure 2 As shown, a plurality of reinforcing fleeces 6 are integrally formed on one side of the thermal insulation sheet 3 close to the inner layer 1. The reinforcing fleece 6 is arranged as a plurality of nylon shaped fibers with a hollow circular cross-sectional shape. The arrangement of the nylon shaped fibers increases the space for air retention inside the reinforcing fleece 6, thereby enhancing the warmth retention of the overall structure. The nylon shaped fibers are twisted by a twisting machine to form nylon yarns, and the nylon yarns are put into a knitting machine to be woven to form the thermal insulation sheet 3. The thermal insulation sheet 3 is put into a sanding machine to be sanded to form the reinforcing fleece 6. During use, part of the reinforcing fleece 6 will extend into the accommodating groove 4, thereby increasing the still air retained on the thermal insulation sheet 3 and increasing the thickness of the thermal insulation sheet 3, further reducing the cold air passing through the fabric.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the inner layer 1 is woven by the warm yarn 7, and the warm yarn 7 includes a warm yarn core 8 and a warm covering yarn 9 spirally wound on the outside thereof. The warm yarn core 8 and the warm covering yarn 9 are processed by the spindle spinning process to form the warm yarn 7. The warm yarn core 8 is twisted by nylon fiber 1 through a twisting machine. Nylon fiber 1 has good elasticity and shape retention. By utilizing the characteristics of nylon fiber 1, the inner layer 1 and the fabric can be restored to their original position under the action of their own elastic deformation properties after deformation, thereby ensuring the normal use of the structure. The warm covering yarn 9 is twisted by graphene fiber through a twisting machine. The fast heating rate of graphene fiber enables the fabric to be in a warm state for a long time, thereby ensuring the warmth and comfort of the fabric when used.

[0025] like Figure 2 and Figure 5 As shown, the outer layer 2 is woven by composite yarn 10, and the composite yarn 10 includes a composite yarn core 11 and a composite covering yarn 12. The composite yarn core 11 and the composite covering yarn 12 are processed by a spindle spinning process to form the composite yarn 10. The composite yarn core 11 is formed by twisting wool fibers through a twisting machine. The wool fibers are naturally curled, thereby increasing the channels for retaining external air in the composite yarn 10 and the outer layer 2, thereby ensuring the warmth retention of the fabric. The composite covering yarn 12 is formed by twisting nylon fibers through a twisting machine.

[0026] like Figure 1-Figure 5 As shown, when the fabric needs to be made, the composite yarn 10 is placed in a knitting machine and woven to form an outer layer 2, the thermal sheet 3 is placed in a sanding machine and sanded to form a reinforcing fleece 6, and then the side of the thermal sheet 3 that does not form the reinforcing fleece 6 is placed toward the outer layer 2 and sewn to the outer layer 2 by a sewing machine, the thermal yarn 7 is placed in the knitting machine and woven by a plush tissue to form an inner layer 1 and thermal fleece 5, a plurality of accommodating grooves 4 are formed along one side of the inner layer 1 by hot pressing with a hot press, the side of the inner layer 1 on which the accommodating grooves 4 are formed is placed upwards, and then the side of the outer layer 2 sewn with the thermal sheet 3 is placed toward the inner layer 1, and finally the inner layer 1 and the outer layer 2 are sewn together by a sewing machine.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
