Abstract
Description
Technical Field
[0001] The utility model relates to a comfortable and warm denim fabric, belonging to the field of textiles. Background Art
[0002] The original denim fabric was woven with cotton fibers as warp and weft yarns, and after cutting and sewing, it became a wear-resistant and thick denim clothing popular among gold miners. With the popularization of denim clothing, people's requirements for denim fabrics began to change from wear resistance to functionality and comfort. In order to meet the needs of different seasons, existing functional denim fabrics include warm fabrics and cool fabrics.
[0003] Existing denim thermal insulation fabrics generally obtain the thermal insulation effect by coating or forming fluff.
[0004] Applying a thermal insulation coating on fabric can improve the warmth retention of the fabric, but after repeated washing, the coating becomes hard and brittle, making the clothing less comfortable, and as the viscosity of the coating decreases, the warmth retention performance also decreases.
[0005] Flocking denim fabrics also uses adhesives, which can also cause the adhesive to become hard and brittle. Fleecing denim fabrics will damage the yarn, reducing the overall strength of the fabric. For denim fabrics that use elastic fibers, the damage is more obvious. Since elastic fibers are usually cotton-wrapped spandex, the elastic fabric is damaged after the fleecing process, and some spandex loses the protection of the cotton coating. After the washing process required for denim clothing, the elastic fabric is prone to loss of elasticity or slippage. Flocked and fleeced fabrics are prone to shedding and tangling of fluff after multiple daily washings. The tangled fluff will affect the comfort of wearing. Utility Model Content
[0006] In order to overcome the deficiencies of the prior art, the utility model provides a comfortable and warm denim fabric.
[0007] The technical solution adopted by the utility model to solve its technical problems is:
[0008] A comfortable and warm denim fabric comprises warp yarns and weft yarns interwoven with each other in a twill, wherein the weft yarns comprise a first weft yarn and a second weft yarn with elasticity, the first weft yarn and the second weft yarn are arranged side by side, the first weft yarn comprises a seaweed fiber yarn core and a moisture-absorbing and heat-generating fiber yarn core, the surface of the seaweed fiber yarn core is coated with a water-soluble coating layer as a first core thread, the surface of the moisture-absorbing and heat-generating fiber yarn core is also coated with the water-soluble coating layer as a second core thread, and the first core thread and the second core thread are jointly coated in a corn fiber coating layer.
[0009] After the comfortable and warm denim fabric provided by the present application is washed at a certain temperature, the water-soluble coating layer dissolves, leaving a cavity in the first weft yarn, and the air in the cavity is difficult to flow, which brings a warming effect. The seaweed fiber yarn core inside has a strong moisture absorption capacity, and the corn fiber outside has a good moisture conduction effect, which is conducive to guiding the water vapor emitted by the human body into the first weft yarn for absorption, and providing the moisture-absorbing and heat-generating fiber to generate heat in the cavity, which can enhance the warming effect, eliminate the stuffy feeling, and avoid the damp and cold feeling. It does not rely on fluff and coating, and has a long-term comfortable and warm effect. After the water-soluble coating layer fades, the cavity is formed, which reduces the strength of the first weft yarn. Accordingly, the first weft yarn and the elastic second weft yarn are side by side, which can make up for the weft strength of the fabric.
[0010] In a preferred embodiment, the first core wire and the second core wire are equal in thickness.

[0012] Furthermore, the ratio of the diameter of the seaweed fiber yarn core to the diameter of the first core line is 1:2-3, and the ratio of the diameter of the moisture-absorbing and heat-generating fiber yarn core to the diameter of the second core line is 2:3-4. In this way, after washing, the remaining cavity is of moderate size, with enough difficult-to-flow air to play a warming role, and is conducive to ensuring the smooth transmission of water vapor in the first weft yarn.
[0013] Furthermore, in each of the first weft yarns, there are three first core wires and three second core wires in total, and they are arranged in a circular array around the axis of the first weft yarn, which is beneficial to suppressing cavity collapse.
[0014] Furthermore, each of the first weft yarns includes two of the first core yarns and one of the second core yarns, which is beneficial for absorbing and utilizing the water vapor emitted by the human body as quickly as possible.
[0015] Furthermore, the first core wire and the second core wire are formed into strands, which is beneficial to enhancing the structural strength of the first weft yarn.
[0016] In a preferred embodiment, the warp yarn is 6S-40S cotton yarn.
[0017] In a preferred embodiment, the second weft yarn is a ply yarn including a cotton single yarn and a T400 fiber single yarn.
[0018] Furthermore, an arrangement ratio of the first weft yarn and the second weft yarn is 3:1.
[0019] The beneficial effects of the utility model are as follows: after the comfortable and warm denim fabric of the utility model is washed at a certain temperature, the water-soluble coating layer dissolves, leaving a cavity in the first weft yarn, and the first weft yarn and the elastic second weft yarn side by side can make up for the weft strength loss caused by the cavity; the air in the cavity is difficult to flow, so that the fabric has a warming effect, the seaweed fiber yarn core inside has a strong moisture absorption capacity, and the corn fiber outside has a good moisture conduction effect, which is conducive to guiding the water vapor emitted by the human body into the first weft yarn for absorption, and providing the moisture-absorbing and heat-generating fiber to generate heat in the cavity, which can enhance the warming effect, absorb and utilize the water vapor emitted by the human body, can eliminate the stuffiness, and avoid the damp and cold feeling, does not rely on fluff and coating, and has a comfortable and warm effect.

DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0026] 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.
[0027] Reference Figure 1 and Figure 3 The embodiment of the present application provides a comfortable and warm denim fabric, including warp yarns 3 and weft yarns interwoven with each other in a twill, the weft yarns including a first weft yarn 1 and a second elastic weft yarn 2, the first weft yarn 1 and the second weft yarn 2 are arranged side by side, the first weft yarn 1 is a core-spun yarn, including a corn fiber coating layer 11, a seaweed fiber yarn core 121 and a hygroscopic and heat-generating fiber yarn core 122, the surfaces of the seaweed fiber yarn core 121 and the hygroscopic and heat-generating fiber yarn core 122 are both coated with a water-soluble coating layer 12, and then coated with the corn fiber coating layer 11. Among them, the hygroscopic and heat-generating fiber yarn core 122 can be hygroscopic and heat-generating nylon, hygroscopic and heat-generating nylon, seaweed fiber, and corn fiber are all existing materials, and those skilled in the art know that through the existing process of coaxial spinning, intertwining and coating, the three fibers can be processed into the same Figure 3 The structure shown.
[0028] The water-soluble coating layer 12 plays a role of temporary support and fixation. Specifically, water-soluble vinylon can be selected. After washing at a certain temperature, the water-soluble coating layer 12 dissolves and fades, which has a certain adverse effect on the strength of the first weft yarn 1. Accordingly, the embodiment of the present application is paralleled with the elastic second weft yarn 2 to supplement the weft strength of the fabric. Specifically, after the denim is made, it usually includes a process of being treated in a hot alkaline solution and washed with hot water, and the temperature reaches 70°C-90°C, which is enough to dissolve most or all of the water-soluble coating layer 12.
[0029] At this time, the first weft yarn 1 includes a corn fiber coating layer 11, a seaweed fiber yarn core 121 and a moisture-absorbing and heat-generating fiber yarn core 122, a first cavity is left between the seaweed fiber yarn core 121 and the corn fiber coating layer 11, and a second cavity is left between the moisture-absorbing and heat-generating fiber yarn core 122 and the corn fiber coating layer 11. In the cavity, air is difficult to flow, and the thermal conductivity of still air is lower than that of general fibers, which brings a warming effect.
[0030] Moreover, the fabric of the embodiment of the present application is both comfortable. The thermal insulation fabric with a heat-insulating coating or with fluff easily accumulates the water vapor emitted by the human body, causing a stuffy feeling. The inner seaweed fiber yarn core 121 has a strong moisture absorption capacity, and the outer corn fiber coating layer 11 has a good moisture conduction effect, which is conducive to guiding the water vapor emitted by the human body into the first weft yarn and supplying the moisture-absorbing and heating fiber yarn core 122 to generate heat in the second cavity, which can enhance the warming effect, absorb and utilize the water vapor emitted by the human body, and eliminate the stuffy feeling. The seaweed fiber yarn core 121 has good moisture absorption, and the outer corn fiber coating layer 11 has good moisture conduction but poor moisture absorption, forming a poor moisture absorption gradient, which is conducive to absorbing water vapor into the first weft yarn 1, rather than letting the water vapor stay on the surface of the first weft yarn 1, which is conducive to avoiding a damp and cold feeling. The embodiment of the present application does not rely on fluff and heat-insulating coatings, and still has a comfortable and warm effect after multiple washings. If the hygroscopic and heating fiber is directly woven into the fabric, the hygroscopic and heating fiber directly contacts the skin, the temperature rises too quickly, and the heat is lost quickly, which will affect the comfort. The embodiment of the present application uses the moisture-absorbing and heat-generating fiber as the core yarn, which can store heat through the cavity, and the generation and loss of heat is relatively moderate, which is more comfortable and natural.
[0031] Reference Figure 1 As a denim fabric, the warp yarn 3 and the weft yarn can be interwoven in a three-up-one-down twill. The warp yarn 3 can be 6S-40S indigo-dyed cotton yarn.
[0032] Preferably, the first core wire and the second core wire are of equal thickness. In each first weft yarn 1, there are three first core wires and second core wires in total, and they are arranged in a circular array around the axis of the first weft yarn 1. This is equivalent to viewing the first weft yarn 1 from a radial cross section, where the three first core wires and second core wires are distributed in a triangular shape, so that the first weft yarn 1 and the cavity have better structural stability. More preferably, the first core wire and the second core wire are in strands, that is, the first core wire and the second core wire are spirally crossed, which can further improve the structural strength of the first weft yarn 1 after the water-soluble coating layer 12 is removed, and inhibit the collapse of the cavity.
[0033] If the space occupied by the hygroscopic and heat-generating fiber yarn core 122 in the first weft yarn 1 is too small, it is difficult to exert the effect of hygroscopic and heat generation. If the space occupied by the seaweed fiber yarn core 121 in the first weft yarn 1 is too small, it is difficult to form a hygroscopic gradient difference to guide water vapor into the first weft yarn 1. Preferably, the radial cross-sectional area of a single seaweed fiber yarn core 121 accounts for 6%-8% of the radial cross-sectional area of the first weft yarn 1, and the radial cross-sectional area of a single hygroscopic and heat-generating fiber yarn core 122 accounts for 9%-12% of the radial cross-sectional area of the first weft yarn 1, which is conducive to ensuring that water vapor is smoothly transmitted in the first weft yarn and has a good warming effect. Similarly, preferably, each first weft yarn 1 includes two first core lines and one second core line, which is conducive to absorbing and utilizing the water vapor emitted by the human body as soon as possible.
[0034] The size of the cavity is related to the warming effect and the structural strength of the first weft yarn 1. If the cavity is too small, the warming effect is insufficient. Preferably, the ratio of the diameter of the seaweed fiber yarn core 121 to the diameter of the first core line is 1:2-3, and the ratio of the diameter of the moisture-absorbing and heat-generating fiber yarn core 122 to the diameter of the second core line is 2:3-4. After washing, the remaining cavity is of moderate size, with enough difficult-to-flow air to play a warming role, and after washing, the strength of the first weft yarn 1 will not be too low.
[0035] In order to further compensate for the decrease in strength of the first weft yarn 1 after the water-soluble coating layer 12 is removed. Figure 2 The second weft yarn 2 is a strand, including a cotton single yarn 21 and a T400 fiber single yarn 22. It has both elastic contraction and breathability effects, and can well support the fabric and supplement the fabric strength. Preferably, the arrangement ratio of the first weft yarn 1 and the second weft yarn 2 is 3:1.
