Abstract
Description
Technical Field
[0001] The utility model belongs to the field of textiles, and particularly relates to an elastic cool-sensation yarn, an elastic cool-sensation denim fabric and a textile product. Background Art
[0002] Denim fabric generally refers to a durable twill fabric made of cotton fiber, linen fiber, polyester or a mixture of these materials, and is famous for its durability and practicality. With the development of society and the improvement of living standards, people's requirements for clothing are also getting higher and higher. Ordinary denim fabrics with only durability and practicality cannot meet people's needs for comfort.
[0003] When the clothing made of denim fabric is worn in hot summer, there are problems of poor heat dissipation and moisture dissipation. Based on this, cool-sensation fabrics are more and more popular among people. A cool-sensation fabric is a fabric that when in contact with the skin, the heat on the skin surface quickly loses and the temperature drops instantly, thus forming a cool feeling. Generally, the cool-sensation fabric needs to be post-finished to make the fabric have the functions of quickly diffusing body heat, accelerating sweating and cooling. However, traditional cool-sensation fibers themselves do not have good elasticity, and the formed woven fabric is a non-elastic fabric or a single weft or single warp elastic fabric combined with elastic fibers.
[0004] It can be seen that most of the existing denim cool-sensation four-way stretch fabrics use the method of double warp shafts plus double weft yarns to make the cool-sensation fabric have four-way stretch, and the weaving process is complex. Therefore, the manufacture of cool-sensation four-way stretch fabrics is a major problem in the textile industry. Summary of the Utility Model

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0027] In this application, unless otherwise clearly specified and defined, when a first feature is described as being "on" or "under" a second feature or similar descriptions, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0028] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.
[0029] In this application, a new type of fiber is formed by combining elastic fiber 102 and cool-sensation fiber 101, so that the cool-sensation fiber 101 has good elasticity, solving the problem that the cool-sensation fiber 101 on the market has no elasticity. Secondly, this elastic cool-sensation fiber 102 is used as warp and weft yarns to prepare a cool-sensation four-way stretch denim fabric that does not exist on the market.
[0030] On the one hand, this application provides an elastic cool-sensation yarn 10, the elastic cool-sensation yarn includes an inner core layer and an outer covering layer, and the outer covering layer covers the inner core layer; the outer covering layer includes cool-sensation fiber 101, and the inner core layer includes elastic fiber 102.
[0031] In a specific example, the elastic cool-sensation yarn 10 further includes a connection layer, and the outer covering layer is connected to the inner core layer through the connection layer.
[0032] Optionally, the connection layer is a structural layer formed by coating one or both of a solvent-based binder and an emulsion-based binder on the inner core layer.
[0033] Among them, the binder can better fix the cool-sensation fiber 101 on the elastic fiber 102, so that the cool-sensation fiber 101 will not come off and separate during the stretching of the elastic fiber 102, and at the same time improves the spinnability of the composite yarn.
[0034] Optionally, when coating, the inner core layer is in a stretched state, and the stretching amplitude of the inner core layer is 90% - 100%.
[0035] When winding, if the elastic fiber 102 is in a stretched state, it can make the cool - feeling fiber 101 combine more closely with the elastic fiber 102. After winding, when the tension is released and it returns to the relaxed state, the contraction is more natural.
[0036] Further optionally, the outer covering layer is wound around the inner core layer in a stretched state in an alternating pattern of S - twist and Z - twist. S - twist and Z - twist are two common yarn twist directions, mainly used in the textile field. The twist direction refers to the helical arrangement direction of the fibers in the yarn. S - twist and Z - twist represent different helical directions respectively. The alternating pattern of S - twist and Z - twist is usually used in certain specific textile processes to obtain better fabric effects.
[0037] For example, mixed twist: During the yarn processing, fibers with S - twist and Z - twist are mixed together to form a new twist direction. This method can increase the elasticity and softness of the yarn. Alternating twist: During the textile process, S - twist and Z - twist yarns are used alternately, making the fabric surface show different textures and visual effects. Composite twist: In some high - requirement textile products, a composite twist method may be used, that is, S - twist and Z - twist are used respectively in the outer layer and the inner layer of the yarn to enhance the stability and strength of the yarn. Spaced twist: During the textile process, S - twist and Z - twist yarns are used alternately at regular intervals to form a spaced texture effect.
[0038] In a specific example, the cool - feeling fiber 101 includes one of lyocell fiber and ice - cool jade fiber.
[0039] Lyocell fiber is a regenerated cellulose fiber prepared from natural cellulose as raw material through an organic solvent spinning process. It has many excellent properties, is known as a green and environmentally friendly fiber, and has broad application prospects.
[0040] In a specific example, the elastic fiber 102 includes one of protein silk, spandex yarn, and rubber yarn.
[0041] Optionally, the elastic fiber 102 includes one of protein silk, spandex yarn, and rubber yarn. Protein silk, spandex yarn, and rubber yarn are three different types of fibers, each with its own unique physical and chemical properties, as well as specific uses in the textile and clothing industries.
[0042] Protein filaments: Protein filaments are fibers made of natural proteins, such as silk. It is made by silkworms spinning silk and is an ancient natural fiber. Protein filaments usually have good luster, softness, and good drapability. Spandex: Spandex is a synthetic elastic fiber, also known as elastane or polyurethane fiber. Spandex has extremely high elasticity, can be stretched several times its original length, and can quickly return to its original shape. Spandex is usually used in combination with other fibers (such as cotton, nylon, or polyester) to increase the elasticity and comfort of the fabric. Rubber filaments: Rubber filaments are fibers made of natural or synthetic rubber and have good elasticity and softness.
[0043] They can also be used in combination with other fibers to increase the elasticity and durability of the fabric.
[0044] On the other hand, this application provides an elastic and cool-sensation denim fabric woven from warp and weft yarns, where at least one of the warp and weft yarns is selected from the above-mentioned elastic and cool-sensation yarn 10.
[0045] Preferably, both the warp and weft yarns are selected from the above-mentioned elastic and cool-sensation yarn 10, thereby forming a four-way stretch fabric effect.
[0046] The two-way stretch and cool-sensation denim fabric is woven by using the above-mentioned elastic and cool-sensation yarn 10 as the warp or weft yarn.
[0047] The four-way stretch and cool-sensation denim fabric is formed by using the above-mentioned formed elastic and cool-sensation yarn 10 as the warp and weft yarns. The elasticity is provided by the elastic fiber 102, and the cool-sensation fiber 101 is used as the outer layer to provide a cool-sensation effect when in contact with the human skin during wearing, improving comfort.
[0048] In a specific example, the woven organizational structure of the warp and weft yarns includes one or two of plain weave, twill weave, and satin weave.
[0049] Optionally, the twill weave includes twill variation weaves.
[0050] Twill woven fabric is a common fabric structure characterized by a twill weave (or twill texture). The surface of the twill fabric has an obvious diagonal texture, which is formed by the arrangement of the interlacing points.
[0051] In a specific example, the yarn count specification of the warp yarn is from 8S to 25S. For example, 8S, 9S, 10S, 11S, 12S, 13S, 14S, 15S, 16S, 17S, 18S, 19S, 20S, 21S, 22S, 23S, 24S, 25S.
[0052] In a specific example, the yarn count specification of the weft yarn is 8S to 25S. For example, 8S, 9S, 10S, 11S, 12S, 13S, 14S, 15S, 16S, 17S, 18S, 19S, 20S, 21S, 22S, 23S, 24S, 25S.
[0053] Optionally, the warp density of the elastic cool-sensation denim fabric is 70 to 100 threads per inch. For example, 70 threads per inch, 75 threads per inch, 80 threads per inch, 85 threads per inch, 90 threads per inch, 95 threads per inch, 100 threads per inch.
[0054] Optionally, the weft density of the elastic cool-sensation denim fabric is 60 to 80 threads per inch. For example, 60 threads per inch, 75 threads per inch, 80 threads per inch.
[0055] On the other hand, this application provides a textile, and at least part of the textile is made of the above-mentioned elastic cool-sensation denim fabric.
[0056] Optionally, the textile includes one or more of clothing, gloves, socks, masks, face towels, and hats.
[0057] When worn in summer, this clothing can bring an ice-sensation experience and a comfortable cool-sensation to consumers, and has good elasticity, which can meet the preferences of consumers and has the dual effects of elasticity and cool-sensation.
[0058] This application provides an elastic cool-sensation yarn 10. The elastic cool-sensation yarn 10 includes a core layer and an outer covering layer, and the outer covering layer covers the core layer; the outer covering layer includes cool-sensation fibers 101, and the core layer includes elastic fibers 102.
