Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, and more specifically, it relates to a thermal insulation yarn and fabric. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the clothing.

[0003] Winter clothing needs to have good warmth retention. To ensure the breathability of the fabric, yarns made of chemical fibers with poor breathability and good abrasion resistance are usually used for weaving. However, the softness and comfort of these fabrics are still inferior to those of natural fibers, and the warmth and comfort of the fabrics need to be improved.

[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 thermal yarn and fabric to improve the overall thermal insulation effect of the fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the yarn body is set as slub yarn, the surface of the yarn body is provided with a number of warming fluffs, the number of warming fluffs on the surface of the yarn body is formed by expanding the yarn body, and the expansion degree of the yarn body is between 15% and 20%.

[0007] The present invention is further configured such that: the yarn body contains a number of polyester fibers and a number of wool fibers, and the twist of the yarn body is between 30-45 twists / 10cm.

[0008] The present invention is further configured as follows: it includes an inner layer and an outer layer that are fixedly connected to each other. The outer layer is woven from heat-insulating yarn. A heat-insulating layer is provided on the end face of the outer layer near the inner layer. A plurality of heat-insulating rings are provided on the end face of the inner layer near the outer layer. Part of the heat-insulating layer abuts against the heat-insulating rings and covers the inner ring of the heat-insulating rings. A plurality of heat-insulating cavities are formed between the inner layer and the outer layer. The height of the heat-insulating layer is less than the height of the heat-insulating rings.

[0009] The present invention is further configured such that: the outer layer of fabric is a plain weave, the inner layer of fabric is a warp-patterned weave, and a plurality of the insulating rings are formed by the warp pattern of the warp-patterned weave.

[0010] The present invention is further configured such that: the ground warp and ground weft yarns of the patterned structure are comfort yarns, and the pattern warp of the patterned structure is abrasion-resistant yarn.

[0011] The present invention is further configured such that: a plurality of anti-sticking elements are provided on the end face of the inner layer away from the outer layer.

[0012] In summary, this utility model has the following beneficial effects: a number of warming fluffs on the surface of the warming yarn form a fluff layer on both sides of the outer layer. As a warming layer, the fluff layer can form an air layer between the fibers, which can effectively slow down the conduction of external temperature, block the entry of cold air, and reduce heat loss. The yarn structure of the warming yarn is slub yarn, and its slub segments will make the surface of the outer layer uneven, which will increase the texture of the outer layer, increase the thickness of the outer layer, and improve the durability and heat insulation effect of the outer layer.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A type of warm yarn, such as Figure 1As shown, the yarn body includes a slub yarn. The surface of the yarn body is covered with several warming fibers 7. These warming fibers 7 are formed by swelling the warming yarn, resulting in a swelling degree between 15% and 20%. The yarn body contains several polyester fibers and several wool fibers. The twist of the yarn body is between 30-45 twists / 10cm. The yarn body, made of polyester and wool fibers, possesses the high strength of polyester and the warmth of wool. In the production of the yarn body, several wool fibers and several polyester fibers are fed into a twisting machine for twisting to obtain base yarn. Then, multiple base yarns are fed into a spinning frame equipped with a slub yarn device. During the spinning process... A slub yarn with several slub segments 5 and ordinary segments 6 is formed. Then, the slub yarn undergoes a swelling treatment, that is, the slub yarn is heated to cause the high-shrinkage polyester fibers to shrink, while the low-shrinkage wool fibers maintain a relatively stable shape. During the shrinkage process, the high-shrinkage fibers will gather in the yarn core, while the low-shrinkage fibers will be squeezed to form loops, which are located on the yarn surface to form warming fluff 7. The swelling degree of the yarn body is between 15% and 20%, while the swelling degree of conventional bulky yarn is about 22%. Since the slub yarn is slub yarn, its swelling degree will be reduced, but the weakening of its yarn strength will be reduced. While ensuring that the yarn body has a good warming effect, its yarn strength can still be guaranteed.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer layer 1 is woven from insulating yarn. The fabric structure of the outer layer 1 is set as plain weave. The insulating yarn is fed into the air-jet loom and woven in the order of plain weave to form a strong and compact outer layer 1. Due to the several insulating piles 7 on the surface of the insulating yarn, a pile layer will be formed on both sides of the outer layer 1. The pile layer, as the insulating layer 101, can form an air layer between the fibers, which can effectively slow down the conduction of external temperature, block the entry of cold air, and reduce heat loss. At the same time, the pile improves the overall hand feel of the outer layer 1, making it soft and fluffy to the touch. In addition, the yarn structure of the insulating yarn is slub yarn, and its slub segments 5 make the surface of the outer layer 1 uneven. While increasing the uneven hand feel of the outer layer 1, it can also increase the thickness of the outer layer 1, improve the durability and heat insulation effect of the outer layer 1.

[0024] like Figure 2 , Figure 3 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the inner layer 2 is a warp-patterned weave. The ground warp and weft yarns of the warp-patterned weave are set as comfort yarns, while the patterned warp yarns are set as abrasion-resistant yarns. The comfort yarns are made of a mixture of polyester and wool fibers twisted together using a twisting machine. Utilizing the high strength and abrasion resistance of polyester fibers and the breathability and warmth of wool fibers, the inner layer 2 possesses warm and comfortable characteristics. The abrasion-resistant yarns are set as nylon yarns. The comfort yarns and abrasion-resistant yarns are fed into a multi-arm loom, following the pattern shown... Figure 7 The weave diagram shows that the fabric has several circular protrusions on the surface, forming a warming ring 3. The hollow part in the middle of the warming ring 3 forms a circular groove 301 on the inner layer 2. Since the fabric structure of the inner layer 2 is a warp-patterned weave, corresponding patterns will be formed on both ends. That is, if a warming ring 3 is formed on one end of the inner layer 2, a cylindrical anti-sticking piece 4 is formed on the other end. The anti-sticking piece 4 on the inner layer 2 can reduce the contact area between the skin and the inner layer 2, and make the pores between the inner layer 2 and the skin larger, thereby increasing the volume of warm air between the fabric and the skin.

[0025] like Figure 2 - Figure 6 As shown, when laminating the inner layer 2 and the outer layer 1, the outer layer 1 is first laid flat on the worktable of an automatic sewing machine. Then, the end face of the inner layer 2 with several insulating rings 3 faces the outer layer 1, and the two layers are brought together. The insulating rings 3 on the inner layer 2 abut against the insulating layer 101 on the outer layer 1. The thickness of the insulating rings 3 is greater than the thickness of the insulating layer 101. Preferably, the thickness of the insulating rings 3 can be controlled by adjusting the yarn thickness of the warp threads. A thicker yarn count can be used to ensure that the thickness of the insulating rings 3 is greater than the thickness of the insulating layer 101, so that insulating cavities 102 can be stably formed. The insulating layer 101 covers part of the insulating rings 3, and several insulating cavities 102 are formed between the insulating rings 3 and the outer layer 1 to reduce the speed of air flow inside the fabric and improve the overall warmth of the fabric. Finally, the inner layer 2 and the outer layer 1 are sewn together to complete the fabric processing.

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.
