Description

Technical Field

[0001] This utility model relates to the field of jacquard fabric technology, and more specifically, it relates to a polyester woven fabric with heat storage and warmth retention. Background Technology

[0002] Jacquard fabric is a cotton or synthetic fiber blended fabric with patterns formed on its surface. With social development, the manufacturing process of jacquard fabric has become more and more mature, and its application range has become more and more extensive.

[0003] Jacquard fabric is also a common type of fabric used to make clothing. Some garments are made of thinner fabrics to ensure lightness during use. However, when the temperature drops, these garments cannot effectively block the cold air from contacting the body, affecting the fabric's warmth retention. Therefore, a structure is designed to solve the problem of poor warmth retention of some fabrics. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyester woven fabric with heat storage and warmth retention, which improves the overall warmth retention performance of the fabric through structural design.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat-retaining and warm polyester woven fabric includes an inner layer and an outer layer that are sewn together and fixed. The outer layer has a number of warm fleece formed on the side near the inner layer through a flocking process. The weaving density of the outer layer is greater than that of the inner layer. The inner layer has a number of contact pieces integrally formed on the side away from the outer layer. The thickness of the contact pieces is less than that of the inner layer. The inner layer has a support piece sewn and fixed on the side near the outer layer that is offset from the contact pieces. The inner layer, outer layer and support piece form a number of warm cavities. The inner layer, outer layer and support piece respectively include polyester hollow special fiber one and polyester hollow special fiber two. The inner layer and the number of contact pieces are integrally formed by plain weave small jacquard weave.

[0006] The present invention is further configured such that: the length of the support piece is equal to the length of the inner layer, and the side of the support piece near the outer layer is recessed inward to form a plurality of receiving grooves.

[0007] The present invention is further configured such that: a plurality of reinforcing fibers are integrally formed on the contact piece; the contact piece is woven from contact yarn; the contact yarn is short fiber yarn; and the contact yarn is formed by twisting polyester profiled fibers.

[0008] The present invention is further configured such that: the inner layer is woven from composite yarn, and the diameter of the composite yarn is larger than the diameter of the contact yarn.

[0009] The present invention is further configured such that: the composite yarn includes a core yarn one and a core yarn two, the core yarn one is formed by twisting polyester fiber one, and the core yarn two is formed by twisting polyester hollow special fiber one.

[0010] The present invention is further configured such that: the outer layer and the support sheet are both woven from thermal insulation yarn, and the thermal insulation yarn includes a core yarn and a covering yarn.

[0011] The present invention is further configured such that: the yarn core is formed by double twisting of polyester fibers, and the covering yarn is formed by double twisting of polyester hollow special fibers.

[0012] In summary, this utility model has the following beneficial effects: the contact piece creates a space between the inner layer and the body surface for outside air to stay. Since air has poor thermal conductivity, the contact piece and the insulation cavity ensure the warmth of the fabric and allow the fabric to bend more effectively under stress, thus enhancing the overall performance of the fabric.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] This is a type of polyester woven fabric with heat-retaining and warmth-insulating properties, such as... Figure 1 and Figure 2As shown, the fabric includes an inner layer 1 and an outer layer 2 that are sewn together. The double-layer fabric design reduces the convection of hot and cold air between the inside and outside of the fabric, enhancing its warmth retention. The outer layer 2, near the inner layer 1, is brushed to form several layers of insulating fleece 3. The addition of the insulating fleece 3 increases the thickness of the outer layer 2, and allows more outside air to be trapped between adjacent layers. Therefore, the characteristics of the insulating fleece 3 are utilized to enhance the overall warmth retention of the fabric. The weave density of the outer layer 2 is greater than that of the inner layer 1; increasing the weave density of the outer layer 2 reduces the thickness of the inner layer 1. The pores formed during weaving reduce the amount of outside air entering the fabric through the pores inside the outer layer 2. The structure ensures the warmth of the fabric during use. The inner layer 1, outer layer 2 and support sheet 5 respectively contain polyester hollow special fiber one and polyester hollow special fiber two. The inner layer 1 and contact sheet 4 are integrally formed by plain weave small jacquard structure. By utilizing this structure and combining the characteristics of polyester hollow special fiber, the fabric surface has a wool-like feel while ensuring structural stability. This allows the fabric to simultaneously provide warmth and comfort.

[0020] like Figure 1-Figure 3 As shown, the inner layer 1 has several contact pieces 4 integrally formed on the side away from the outer layer 2. The thickness of the contact pieces 4 is less than that of the inner layer 1. The contact pieces 4 reduce the contact area between the inner layer 1 and the body surface, creating a channel for air retention. Air has poor thermal conductivity, which ensures the warmth retention of the inner layer 1. The channel also allows the inner layer 1 to bend more effectively under stress. Several reinforcing fleece 7 are integrally formed on the contact pieces 4. The reinforcing fleece 7 further increases the thickness of the contact pieces 4 and increases the space for air retention inside the structure. The contact pieces 4 are woven from contact yarn, which is a short fiber yarn. The contact yarn is made by twisting polyester profiled fibers. The cross-sectional shape of the polyester profiled fibers is a hollow circle. The space of the polyester profiled fibers increases the amount of air that can be retained inside the contact pieces 4. The polyester profiled fibers are cut into short fibers by a cutting machine, and then the cut fibers are put into a cotton blending machine for twisting to form contact yarn.

[0021] like Figure 1 and Figure 2As shown, a support piece 5, which is offset from the contact piece 4, is sewn onto the side of the inner layer 1 near the outer layer 2 by a sewing machine. The inner layer 1, outer layer 2, and support piece 5 form several insulating cavities. The insulating cavities further increase the amount of still air that can be retained between the inner layer 1 and the outer layer 2. Due to the staggered arrangement of the support piece 5 and the contact piece 4, the thickness of the inner layer 1 is relatively uniform, and the staggered arrangement of the two can ensure that different parts of the fabric can be stably supported, ensuring the stable use of the structure. The length of the support piece 5 is equal to the length of the inner layer 1, ensuring the stability of the support piece 5 in supporting the outer layer 2 and ensuring the stable formation of the insulating cavities. Several receiving grooves 6 are formed on the side of the support piece 5 near the outer layer 2 by a hot press. The setting of the receiving grooves 6 increases the content of still air inside the support piece 5, and the pores on the bottom of the receiving grooves 6 formed by the hot press are sealed by the melted fibers, thereby further reducing the amount of cold air that passes through the support piece 5 and comes into contact with the inner layer 1 and the body surface.

[0022] like Figure 1 and Figure 3 As shown, the inner layer 1 is woven from composite yarn 8. The diameter of composite yarn 8 is larger than that of the contact yarn, so the thickness of the inner layer 1 is greater than that of the contact sheet 4, which allows the inner layer 1 to better insulate against cold air. The composite yarn 8 includes core yarn 1 9 and core yarn 2 10. Core yarn 1 9 and core yarn 2 10 are twisted by a twisting machine to form composite yarn 8. Core yarn 1 9 is made of polyester fiber 1 by twisting machine. Polyester fiber 1 has good structural strength and shape retention. The characteristics of polyester fiber 1 are used to ensure the wear resistance and durability of the structure. Core yarn 2 10 is made of polyester hollow special fiber 1 by twisting machine. Polyester hollow special fiber 1 has good elasticity, which allows the fabric to return to its initial position better after stretching.

[0023] like Figure 1 and Figure 4 As shown, the outer layer 2 and the support sheet 5 are both woven from the insulating yarn 11. The insulating yarn 11 includes a yarn core 12 and a covering yarn 13. The yarn core 12 and the covering yarn 13 are processed by a spinning process to form the insulating yarn 11. The yarn core 12 is made of polyester fiber II by twisting it with a twisting machine. The covering yarn 13 is made of polyester hollow special fiber II by twisting it with a twisting machine. The polyester hollow special fiber II is naturally crimped, so there is more space for air to be retained inside the structure, which enhances the overall insulating effect of the structure.

[0024] like Figure 1-Figure 4As shown, when this fabric is to be made, the composite yarn 8 and the contact yarn are placed in a jacquard loom and woven into an inner layer 1 and several contact pieces 4 through a plain jacquard weave. The thermal insulation yarn 11 is placed in a shuttle loom and woven into an outer layer 2 and a support layer. Several receiving grooves 6 are formed by hot pressing along one side of the support layer through a hot press. Then, the support layer is cut into several support pieces 5 through a laser cutter along the thickness direction. The support pieces 5 are sewn onto the inner layer 1 through a sewing machine. Several thermal insulation fleece 3 are formed on one side of the outer layer 2 through a napping machine. Finally, the inner layer 1 and the outer layer 2 are sewn together through a sewing machine.

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.
