Description

Technical Field

[0001] The utility model relates to the technical field of textile clothing, in particular to a moisture-absorbing and quick-drying fabric. Background Art

[0002] As people's requirements for quality of life become higher and higher, clothing fabrics must not only meet the requirements of covering and aesthetics, but also be more comfortable to wear. The comfort of clothing has gradually become the primary consideration when people choose clothing.

[0003] During hot summer months, people want to enjoy their sports without the worry of sweating and the stuffy, damp weather. This creates higher demands on fabrics with excellent moisture-wicking properties. Pure cotton clothing is particularly popular in the apparel market. However, when sweating profusely, cotton fibers, due to their excellent hygroscopicity, absorb large amounts of sweat, becoming wet and heavy. This adheres to the skin, slowing down moisture conduction and release, affecting the microclimate between the skin and the clothing and the exchange of heat and moisture between the clothing and the outside world. Furthermore, pure cotton clothing has poor elasticity, making it uncomfortable to wear during summer sports. Utility Model Content

[0004] In view of this, the present invention aims to provide a moisture-absorbing and quick-drying fabric to solve the problems of slow moisture absorption and quick drying and poor elasticity of pure cotton clothing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A moisture-absorbing quick-drying fabric comprises a face veil and a first ground yarn, wherein the face veil and the first ground yarn are woven to form a plated plain weave, the face veil is a blended yarn formed by blending first pure cotton fiber and hollow polyester fiber, and the first ground yarn is an elastic yarn.

[0007] The utility model adopts the first ground yarn to weave a fabric with good elasticity, which is more comfortable to wear when exercising and sweating in the summer. At the same time, it is woven with a blended yarn of hollow polyester fiber and cotton fiber. The cotton fiber has strong moisture absorption capacity. It is a porous substance with very irregular internal molecular arrangement and contains a large number of hydrophilic structures in the molecules. The porous polyester fiber is a hollow fiber with a new type of hollow structure and groove channels. It has a hollow structure and groove channels that are intricate and stretching like loofah. The hollow structure enhances the capillary effect of the fabric when absorbing water. Sweat can be quickly absorbed by the fabric and diffused to the outer surface of the clothing for evaporation, keeping the skin continuously dry and comfortable.

[0008] Furthermore, the specification of the face veil is 20-40S, and the specification of the first ground veil is 20-40D.

[0009] Furthermore, the specification of the face veil is 30S, and the specification of the first ground veil is 20D.

[0010] Furthermore, the blending form of the first pure cotton fiber and the hollow polyester fiber is siro-compact spinning.

[0011] This blending form can reduce the hairiness and make the fabric have excellent anti-pilling properties.

[0012] Furthermore, the cross section of the hollow polyester fiber is circular.

[0013] Furthermore, the loop length of the face yarn is greater than the loop length of the first ground yarn.

[0014] This arrangement enables the face veil to cover the first ground veil. On the basis of the first ground veil maintaining the elasticity of the fabric, the fabric has better moisture absorption and quick-drying properties through the weaving of the face veil.

[0015] Furthermore, the loop value range of the surface yarn is 14 to 16 cm / 50 needles, and the loop value range of the first ground yarn is 5 to 6 cm / 50 needles.

[0016] Furthermore, the loop length of the face yarn is a1, and the loop length of the first ground yarn is a2, wherein a1 / a2=2.8-3.2.

[0017] Furthermore, the fabric is knitted using a circular knitting machine.

[0018] Furthermore, the machine gauge of the large circular knitting machine is 24-28G.

[0019] Compared with the prior art, the moisture-absorbing and quick-drying fabric described in the present invention has the following advantages:

[0020] 1) The utility model adopts the first ground yarn and the face yarn to knit the obtained fabric with good elasticity, which is more comfortable to wear when exercising and sweating in the summer. At the same time, it is woven with the blended yarn of hollow polyester fiber and first pure cotton fiber. The first pure cotton fiber has strong moisture absorption capacity. It is a porous material with very irregular internal molecular arrangement and contains a large number of hydrophilic structures in the molecules. The porous polyester fiber is a hollow fiber with a new type of hollow structure and groove channels. It has a hollow hollow structure and groove channels that are as intricate and long as the sponge of a loofah. The hollow structure enhances the capillary effect of the fabric when absorbing water. Sweat can be quickly absorbed by the fabric and diffused to the outer surface of the clothing for evaporation, keeping the skin dry and comfortable.

[0021] 2) The positional relationship and loop length of the face veil, first ground veil, and second ground veil of the present invention are such that the face veil covers the first and second ground veils, thereby improving the moisture conduction and quick-drying properties of the fabric. Meanwhile, the second ground veil covers the first ground veil, so that the first ground veil is located between the second ground veil and the face veil, thereby providing the fabric with better dimensional stability. Even after washing, the fabric still maintains good moisture absorption and quick-drying properties.

[0022] 3) The utility model uses the special-shaped polyester yarn to not only quickly guide sweat to the outside of the skin, but also reduce the time that sweat contacts the skin, thereby improving the comfort of users wearing the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 As shown, the present invention provides a moisture-absorbing and quick-drying fabric, which is knitted into a plated plain weave using a circular knitting machine with a gauge of 24G or 28G, preferably a gauge of 24G. The fabric includes a face veil 1 and a first ground yarn 2, which are woven into a plated plain weave. The face veil 1 covers the first ground yarn 2, with the face veil 1 on the front side of the fabric and the first ground yarn 2 on the back side of the fabric. The face veil 1 is a blended yarn of first pure cotton fiber and hollow polyester fiber, and the first ground yarn 2 is spandex yarn. The "upper" direction in this embodiment refers to the side away from the skin when the human body wears the fabric, and the side close to the skin is "lower".

[0031] In this embodiment, spandex yarn is used as the first ground yarn to make the fabric have better elasticity, which is more comfortable to wear when exercising and sweating in the summer; the first pure cotton fiber is long-staple cotton, which has strong moisture absorption capacity. It is a porous material with a very irregular internal molecular arrangement and contains a large number of hydrophilic structures in the molecules, which can quickly absorb sweat and keep the skin dry; the hollow polyester fiber is a short fiber with a circular cross-section, a length of 38mm, and a fineness of 1.56dtex. The hollow polyester fiber has a loofah-like intricate and long hollow structure and groove channels, which can pass through the water absorption of the first pure cotton fiber, so that sweat can quickly reach the channels of the hollow polyester fiber. The hollow structure enhances the capillary effect of the fabric when absorbing water. Sweat can be quickly absorbed by the fabric and diffused to the outer surface of the clothing for evaporation, keeping the skin continuously dry, comfortable and cool.

[0032] Specifically, the mass percentage of the first pure cotton fiber and the hollow polyester fiber in the blended yarn is 30-40:70-60. Preferably, the mass percentage of the first pure cotton fiber and the hollow polyester fiber is 35:65.

[0033] Specifically, the specification of the face veil is 20-40S, and the specification of the first ground veil is 20-40D. Preferably, the specification of the face veil is 30S, and the specification of the first ground veil is 20D.

[0034] Specifically, the blending form of the first pure cotton fiber and the hollow polyester fiber is siro-compact spinning, which can reduce hairiness and make the fabric have excellent anti-pilling properties.

[0035] Specifically, the coil length of the face veil 1 is greater than the coil length of the first ground yarn 2, the coil length of the face veil is a1, and the coil length of the first ground yarn is a2, wherein a1 / a2=2.8~3.2; preferably, the coil value range of the face veil 1 is 14~16cm / 50 needles, and the coil value range of the first ground yarn 2 is 5~6cm / 50 needles; more preferably, the coil value range of the first ground yarn is 15cm / 50 needles, and the coil range of the face veil is 5cm / 50 needles.

[0036] Example 2

[0037] 4) If Figure 2As shown, this embodiment is different from Example 1 in that the fabric also includes a second ground yarn, which is located below the first ground yarn, that is, the first ground yarn is located between the second ground yarn and the face yarn, and the second ground yarn is a shaped polyester yarn, and the cross-sectional structure of the shaped polyester yarn is one of Y-type, X-type, and cross-type. Preferably, the cross-sectional structure of the shaped polyester yarn is cross-shaped, the thickness of the shaped polyester yarn is 50~100D, and the fineness is 84~120F. Preferably, the specification of the shaped polyester yarn is 75D / 100F, and the coil value range of the second ground yarn is a3, wherein a1>a3≥a2. This setting makes the face yarn cover the first ground yarn and the second ground yarn, thereby improving the moisture conduction and quick-drying function of the fabric. At the same time, the second ground yarn covers the first ground yarn, so that the first ground yarn is located between the second ground yarn and the face yarn, so that the fabric has better dimensional stability, and even after the fabric is washed, it still maintains good moisture absorption and quick-drying properties.

[0038] Specifically, the coils of the second ground yarn are 0.3 to 0.8 cm / 50 stitches longer than the coils of the first ground yarn. Preferably, the coils of the shaped polyester yarn are in the range of 5 to 7 cm / 50 stitches, and more preferably, the coils of the shaped polyester yarn are in the range of 5.5 cm / 50 stitches.

[0039] This embodiment arranges special-shaped polyester yarns at the bottom of the spandex to directly guide sweat to the outside of the skin, thereby reducing the contact time between sweat and skin and improving the comfort of users wearing the fabric. In addition, this embodiment cleverly uses the upper and lower needle arrangement method on the spandex needles, and the spandex is located in the middle, so that the fabric does not fall apart. The garment factory can cut it at will without locking the edges, achieving a seamless and more comfortable effect.

[0040] Example 3

[0041] The difference between this embodiment and embodiment 2 is that the first ground yarn is a composite yarn, wherein the first ground yarn 2 includes spandex fiber 21, second pure cotton fiber 22, and antibacterial fiber 23. Figure 3 As shown, the second pure cotton fiber 22 and the antibacterial fiber 23 are arranged side by side and coated on the outer surface of the spandex fiber 21; the spandex fiber 21 is simultaneously combined with the second pure cotton yarn 22 and the antibacterial fiber 23. This arrangement can not only ensure the strength and elasticity of the composite yarn, improve the dimensional stability of the fabric, and make the fabric washable, but also the second cotton fiber 22 in the composite yarn can quickly absorb moisture in the grooves of the shaped polyester yarn, and then the moisture is absorbed by the second cotton fiber and transported to the hollow polyester fiber, and quickly conducts moisture to the outer layer. In addition, the antibacterial fiber 23 in the first ground yarn has an antibacterial effect, which effectively removes fungi, bacteria and mold on the fabric and prevents bacterial reproduction.

[0042] Specifically, the antibacterial fiber includes one of cuprammonium fiber, lyocell fiber, jute fiber, ramie fiber, and ula grass fiber. Preferably, the antibacterial fiber 23 is cuprammonium fiber.

[0043] Specifically, the mass ratio of cupro-ammonia fiber: spandex fiber: second pure cotton fiber is 40:3:57, and the specification of the first ground yarn is 30D.

[0044] Comparative Example 1

[0045] The difference between this comparative example and Example 3 is that the loop value range of the first ground yarn is 6.5 cm / 50 needles, the loop value range of the second ground yarn is 6 cm / 50 needles, and the loop range of the face yarn is 16.5 cm / 50 needles.

[0046] Comparative Example 2

[0047] The difference between this comparative example and Example 3 is that the loop value range of the first ground yarn is 4.5 cm / 50 needles, the loop value range of the second ground yarn is 6 cm / 50 needles, and the loop range of the face yarn is 13.5 cm / 50 needles.

[0048] Experimental example

[0049] In order to further illustrate the technical advancement of the present invention, experiments are now used to further illustrate it.

[0050] Experimental method: The moisture absorption and quick-drying test was carried out with reference to GB / T21655.1-2008 “Evaluation of moisture absorption and quick-drying properties of textiles”. The moisture absorption and quick-drying properties of Examples 1 to 3 and Comparative Examples 1 to 2 were tested. The test results are shown in Table 1.

[0051] Table 1:

[0052]

[0053] It can be concluded from Table 1 that the fabric obtained by knitting the first ground yarn and the face yarn in the present invention has good elasticity. At the same time, it is knitted with a blended yarn of porous polyester fiber and first pure cotton fiber. The first pure cotton fiber has strong moisture absorption capacity. It is a porous substance with a very irregular arrangement of internal molecules and contains a large number of hydrophilic structures in the molecules. The porous polyester fiber is a hollow fiber with a new type of hollow structure and groove channels. It has a hollow hollow structure and groove channels that are as intricate and long as the sponge of a loofah. It can make water flow quickly along the hollow hollow structure and groove channels, quickly transfer body sweat, and guide moisture away from the skin surface, keeping the skin dry and cool.

[0054] It can be found from Examples 1 to 3 and Comparative Documents 1 to 2 that when the coil length is too long, the fabric structure becomes looser, reducing its tightness and stability, thereby affecting the overall performance of the fabric, especially the fabric has poor dimensional stability after washing, resulting in a further decrease in the moisture absorption and quick-drying properties of the fabric; when the coil length is too short, the coil may cause the fabric structure to be tighter and the space between the fibers to be reduced, which may limit the diffusion and conduction of water between the fibers, thereby affecting its moisture absorption and quick-drying properties. In this application, the selection of yarn, the structure of the yarn, the coil length formed by the yarn, etc. are coordinated with each other, and the long-lasting moisture absorption and quick-drying function of the fabric can be achieved without dyeing or other post-processing steps, making the process of preparing the fabric more environmentally friendly.

[0055] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
