Description

Technical Field

[0001] The utility model relates to a novel warm-keeping fabric and belongs to the field of textiles. Background Art

[0002] In addition to satisfying the three basic functions of covering one's modesty, keeping out the cold and looking beautiful, people are paying more and more attention to the health and comfort of clothing. In the cold winter, people usually wear warm clothing to keep out the cold. At present, the technical directions for enhancing the warmth retention of fabrics are mainly divided into three categories: one is to weave fabrics with yarns with heating function, the second is to apply a coating with warmth retention to the fabric, and the third is to provide more structures that can hinder air flow.

[0003] Regarding the third category, the principle used is that the thermal conductivity of still air is lower than that of general fibers. A specific example is fleecing during post-finishing, where numerous fleeces hinder air flow, causing the air to be trapped between the fleeces, thereby achieving warmth retention. Another example is down, where duck down is filled between two layers of cloth, causing the air to remain between the two layers of cloth and become difficult to flow. Another example is some cotton-padded clothes, where chemical fibers are filled between two layers of cloth to achieve a similar effect to down. However, down, cotton-padded clothes, and fleece fabrics all have the defect of being difficult to care for. After daily washing, the fleece structure tends to tangle into balls and is difficult to disperse, causing the space where air should be retained to collapse, resulting in a decrease in warmth retention. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a novel thermal insulation fabric which also utilizes the principle of still air insulation and is not easy to collapse after washing and is easier to take care of.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A new type of thermal insulation fabric comprises a first base fabric layer, a second base fabric layer and a hot pressing layer connected between the first base fabric layer and the second base fabric layer, the hot pressing layer has a wavy structure, a first air chamber is formed between the hot pressing layer and the first base fabric layer, a second air chamber is formed between the hot pressing layer and the second base fabric layer, the first base fabric layer comprises a first yarn, a first cavity is arranged on the first yarn, and the second base fabric layer comprises a second yarn, hollow particles are arranged on the second yarn.

[0007] The new thermal insulation fabric provided by the present application utilizes a wavy heat-pressed layer to connect a first base fabric layer and a second base fabric layer, and relies on the wavy structure to maintain a certain distance between the first base fabric layer and the second base fabric layer. In addition, the first base fabric layer can be designed to be the outward side of the clothing, and the first yarn in the first base fabric layer relies on the first cavity to retain air. The second base fabric layer is designed to be the inward side of the clothing. In order to adapt to the characteristic that the inward side of the clothing is easily compressed, hollow particles are used to retain air, which is more stable than the first cavity. The new thermal insulation fabric does not need to use a fluffy structure to form a space for retaining air, is not easy to collapse after washing, and is easier to care for.

[0008] Furthermore, the first yarn is 16S-40S sea island cotton yarn. The fiber of sea island cotton is longer than that of ordinary cotton. The 16S-40S sea island cotton yarn is used as the first yarn and is used on the outer side of the clothing. It has a smooth and delicate feel and better moisture absorption and air permeability.

[0009] Furthermore, the second yarn is a core-spun yarn, including a polylactic acid fiber yarn core and a chitin fiber coating layer, and the hollow particles are arranged in the polylactic acid fiber yarn core. The polylactic acid fiber yarn core can provide good strength and resilience for the second yarn, and the polylactic acid fiber yarn core, as a chemical fiber, can well fix the hollow particles. In addition, the second base fabric layer is used for the inner side of the clothing, and the chitin fiber coating layer can provide a certain antibacterial effect for a relatively humid and hot environment.

[0010] Furthermore, the diameter of the polylactic acid fiber yarn core accounts for 5 / 7-6 / 7 of the diameter of the second yarn, which is conducive to the second yarn having stronger elasticity and warmth-keeping effect.

[0011] Furthermore, the heat-pressed layer is a waterproof and breathable film with a thickness of 80 μm-150 μm. The thickness here includes the thickness of the wavy bend. The waterproof and breathable film exists between the first base fabric layer and the second base fabric layer, and can discharge the excess moisture generated by the human body to the first base fabric layer, prevent the hot air from returning to the second base fabric layer when it encounters cold, and reduce the degree of moisture and heat on the inner side of the clothes when worn. The second yarn of the core-spun yarn structure has a better antibacterial effect.

[0012] Furthermore, the thickness ratio of the first base fabric layer, the heat-pressed layer, and the second base fabric layer is 2-5:1:2-5. The thickness of the heat-pressed layer here is still a thickness including a wavy bend, and this thickness ratio can ensure that the first air chamber and the second air chamber have enough space to hinder air flow.

[0013] In a preferred embodiment, the first base fabric layer and the second base fabric layer are both woven fabrics.

[0014] Furthermore, the weave structure of the first base fabric layer is plain weave, twill weave or satin weave, and the weave structure of the second base fabric layer is plain weave, twill weave or satin weave.

[0015] Furthermore, the first yarn is a weft yarn of the first base fabric layer, and the second yarn is a weft yarn of the second base fabric layer.

[0016] Furthermore, the warp yarn of the first base fabric layer is 6S-50S cotton yarn, and the warp yarn of the second base fabric layer is 6S-50S cotton yarn.

[0017] The beneficial effects of the utility model are as follows: the first base fabric layer and the second base fabric layer are connected by utilizing a wavy heat-pressed layer, and a certain distance is maintained between the first base fabric layer and the second base fabric layer by relying on the wavy structure; in addition, the first base fabric layer can be designed as the outward side of the clothing, the first yarn in the first base fabric layer relies on the first cavity to retain air, and the second base fabric layer is designed as the inward side of the clothing. In order to adapt to the characteristic that the inward side of the clothing is easily compressed, hollow particles are used to retain air, which is more stable than the first cavity. The novel thermal insulation fabric does not need to utilize a fluff-like structure to form a space for retaining air, is not easy to collapse after washing, and is easier to care for.

[0027] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] Reference Figures 1 to 3 The embodiment of the present application provides a new type of thermal insulation fabric, including a first base fabric layer 1, a second base fabric layer 2 and a hot pressing layer 3 connected between the first base fabric layer 1 and the second base fabric layer 2, the hot pressing layer 3 has a wavy structure, a first air chamber 31 is formed between the hot pressing layer 3 and the first base fabric layer 1, and a second air chamber 32 is formed between the hot pressing layer 3 and the second base fabric layer 2, the first base fabric layer 1 includes a first yarn, and a first cavity 111 is arranged on the first yarn, and the second base fabric layer 2 includes a second yarn, and hollow particles 211 are arranged on the second yarn.

[0029] Specifically, the hollow particles 211 may be hollow microcapsules, which are existing raw materials and have a certain rebound effect.

[0030] The first cavity 111 in the first yarn can be obtained in the following way: using sea island cotton and water-soluble fiber (such as water-soluble PVA staple fiber) as raw materials, the yarn is made by embedded spinning, and after weaving, in the necessary washing process for fabric finishing, the water-soluble fiber is dissolved to form cavities of different sizes. Compared with the conventional single-hole cavity in the center of the yarn, the first cavity 111 formed in this way is dispersed in position and of different sizes. When subjected to external pressure, they can share the pressure with each other. Therefore, the first cavity 111 is not easy to collapse and has a longer-lasting warmth-keeping effect.

[0031] The connection of the first base fabric layer 1 and the second base fabric layer 2 by using the wavy hot pressing layer 3 can be achieved by the following spinning: using a wavy template to transform the hot pressing film into a hot pressing layer under heating, and then laminating the first base fabric layer 1 and the second base fabric layer 2 on both sides of the hot pressing layer 3 while they are still hot.

[0032] The new thermal insulation fabric of the embodiment of the present application utilizes a wavy heat-pressed layer 3 to connect the first base fabric layer 1 and the second base fabric layer 2, and relies on the wavy structure to maintain a certain distance between the first base fabric layer 1 and the second base fabric layer 2. In addition, the first base fabric layer 1 can be designed as the outward side of the clothing, and the first yarn in the first base fabric layer 1 relies on the first cavity 111 to retain air. The second base fabric layer 2 is designed as the inward side of the clothing. In order to adapt to the characteristic that the inward side of the clothing is easily compressed, hollow particles 211 are used to retain air, which is more stable than the first cavity 111. The new thermal insulation fabric does not need to use a fluffy structure to form a space for retaining air, is not easy to collapse after washing, and is easier to care for.

[0033] Specifically, the first base fabric layer 1 and the second base fabric layer 2 are both woven fabrics, which are not easy to curl and are more convenient to be attached to the hot pressing layer 3 while hot. The weave structure of the first base fabric layer 1 and the second base fabric layer 2 can be plain, twill or satin. If the texture of denim fabric is to be imitated, the first base fabric layer 1 and the second base fabric layer 2 can be woven into twill, the first yarn is the weft yarn of the first base fabric layer 1, the second yarn is the weft yarn of the second base fabric layer 2, and the warp yarn of the first base fabric layer 1 and the warp yarn of the second base fabric layer 2 are 10S-40S indigo-dyed cotton yarn.

[0034] In a preferred embodiment, the first yarn is 16S-40S sea island cotton yarn. The fiber of sea island cotton is longer than that of ordinary cotton. 16S-40S sea island cotton yarn is used as the first yarn and is used on the outer side of the garment. It has a smooth and delicate feel and better moisture absorption and air permeability.

[0035] Reference Figure 3 The second yarn is a core-spun yarn, including a polylactic acid fiber yarn core 21 and a chitin fiber coating layer 22, and the hollow particles 211 are arranged in the polylactic acid fiber yarn core 21. The polylactic acid fiber yarn core 21 can provide good strength and resilience for the second yarn, and the polylactic acid fiber yarn core 21, as a chemical fiber, can well fix the hollow particles 211. In addition, the second base fabric layer 2 is used for the inner side of the clothing, and the chitin fiber coating layer 22 can provide a certain antibacterial effect for a relatively humid and hot environment.

[0036] The hollow particles 211 can be arranged in the polylactic acid fiber yarn core 21 in the following manner: the hollow particles 211 are dispersed in the spinning solution of the polylactic acid fiber, and after spinning, the polylactic acid fiber yarn core 21 with the hollow particles 211 arranged inside can be obtained.

[0037] Preferably, the diameter of the polylactic acid fiber yarn core 21 accounts for 5 / 7-6 / 7 of the diameter of the second yarn, which is conducive to the second yarn having stronger elasticity and warmth-keeping effect.

[0038] Correspondingly, the heat-pressed layer 3 is a waterproof and breathable film with a thickness of 80μm-150μm. The thickness of the waterproof and breathable film on the market is about 20μm-40μm. After the template is hot-pressed, it can have a thickness of 80μm-150μm. Preferably, the thickness ratio of the first base fabric layer 1, the heat-pressed layer, and the second base fabric layer 2 is 2-5:1:2-5. The use of this thickness ratio can ensure that the first air chamber 31 and the second air chamber 32 have sufficient space to hinder air flow.

[0039] It should be noted that the first air chamber 31 and the second air chamber 32 only need to hinder the air flow and slow down the flow rate, and do not have to form a closed space. Of course, after using the waterproof and breathable membrane, the warmth retention ability is slightly reduced compared to using the non-permeable heat-pressed layer 3, but this embodiment also has a better antibacterial effect. The waterproof and breathable heat-pressed layer exists between the first base fabric layer 1 and the second base fabric layer 2. It can discharge the excess moisture generated by the human body to the first base fabric layer 1, and with the moisture absorption capacity of the 16S-32S sea island cotton yarn, it can prevent the hot air from returning to the second base fabric layer 2 when it encounters cold, and reduce the degree of moisture and heat on the inner side of the clothes when worn. The second yarn of the core-spun yarn structure has a better antibacterial effect.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0041] The above is a preferred embodiment of the present invention.

These improvements and modifications are also considered to be within the protection scope of the present invention.
