Description

Technical Field

[0001] This invention relates to the field of textile materials technology, specifically to a two-color, double-sided fabric and its preparation method. Background Technology

[0002] As people continuously pursue a better life, their demands for the aesthetics, comfort, and functionality of clothing fabrics are increasing. Two-tone, double-sided fabrics are popular with consumers due to their ability to present different colors on the front and back, offering excellent aesthetics. However, current two-tone, double-sided fabrics still have some problems. For example, Chinese invention patent application number 201710663447.0 discloses a double-sided, two-tone woolen fabric, including a first woolen layer and a second woolen layer. It achieves a two-tone effect and warmth by dyeing the first and second woolen layers with different colors. However, this invention achieves warmth by increasing the fabric thickness to reduce heat loss from the body; the resulting bulkiness affects the fabric's softness, skin-friendliness, and wearing comfort. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a two-color, double-sided fabric that combines the feel of skin-friendly cotton with light absorption and heat generation, and a method for preparing the same.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a two-color double-sided fabric, woven from warp and weft yarns, wherein the warp yarn is a first ATY yarn and the weft yarn is a second ATY yarn; the first ATY yarn and the second ATY yarn have different matting degrees; either the first ATY yarn or the second ATY yarn includes a DTY yarn, and the other is composed of FDY yarn.

[0005] Another technical solution adopted in this invention is: the preparation method of the above-mentioned two-color double-sided fabric includes the following steps: using warp and weft yarns to weave a greige fabric, and the greige fabric is successively processed by fabric preparation, scouring, dyeing, dehydration, spreading and setting to obtain the two-color double-sided fabric.

[0006] The beneficial effects of this invention are as follows: In the two-color double-sided fabric of this invention, the warp yarn is a first ATY yarn and the weft yarn is a second ATY yarn. The ATY process gives the yarn a fluffy, breathable, soft, and cotton-like feel. Using different matte finishes for the warp and weft yarns will create a difference in visual color. Simultaneously, either the first ATY yarn or the second ATY yarn includes a DTY yarn, while the other is composed entirely of FDY yarn. During the dyeing process, the FDY yarn, with its smooth surface, has a lighter and brighter color, while the DTY yarn, with its rough surface, has a darker and darker color. This results in a two-color double-sided fabric with different colors on the front and back sides. Attached Figure Description

Detailed Implementation

[0008] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0009] A two-tone, double-sided fabric woven from warp and weft yarns, wherein the warp yarns are first ATY yarns and the weft yarns are second ATY yarns; the first ATY yarns and the second ATY yarns have different matte finishes; either the first ATY yarn or the second ATY yarn includes a DTY yarn, and the other is composed of FDY yarns.

[0010] ATY is air-textured yarn, DTY is stretch-textured yarn, and FDY is fully stretched yarn.

[0011] As can be seen from the above description, the beneficial effects of the present invention are as follows: The preparation step of ATY involves using an air jet method to interweave the yarn bundle with air jet technology, forming irregularly twisted yarn loops, giving the yarn bundle a fluffy, looped yarn appearance. In the two-color double-sided fabric of the present invention, the warp yarn is the first ATY yarn, and the weft yarn is the second ATY yarn. The ATY process gives the yarn a fluffy, breathable, soft, and cotton-like feel. Different matte finishes on the warp and weft yarns will cause differences in visual color. Either the first ATY yarn or the second ATY yarn includes a DTY yarn, while the other is composed of an FDY yarn. Due to the different spinning methods, the FDY and DTY yarns have different surface structures, resulting in different colors during the fabric dyeing process. The FDY yarn has a smooth surface and a lighter color, while the DTY yarn has a rough surface and a darker color, thus obtaining a two-color double-sided fabric with different colors on the front and back.

[0012] Furthermore, the first ATY yarn is composed of a quick-heating yarn and an elastic yarn.

[0013] As described above, using a composite of fast-heating yarn and elastic yarn to create ATY allows the yarn to simultaneously possess light-absorbing and heat-generating properties, as well as elasticity. The elasticity causes the yarn to shrink, increasing the fabric density. Combined with appropriate weave structure, this allows one side of the fabric to be entirely covered by fast-heating yarn, enhancing its light-absorbing and heat-generating effect. Compared to relying on thickness for insulation, using fast-heating yarn to achieve light-absorbing and heat-generating effects results in a lighter and thinner fabric, providing superior wearing comfort.

[0014] Furthermore, the first ATY yarn is composed of a fully dull DTY quick-heating yarn and a semi-dull elastic yarn, and the second ATY yarn is composed of a semi-dull FDY yarn A and a semi-dull FDY yarn B.

[0015] Furthermore, semi-dull FDY yarn A is a semi-dull 75D / 36F polyester FDY yarn, and semi-dull FDY yarn B is a semi-dull 75D / 72F polyester FDY yarn.

[0016] Furthermore, the elastic yarn is T400 yarn.

[0017] As described above, T400 yarn is a parallel composite fiber spun from two polymers with different shrinkage rates: PTT (poly(1,3-propylene terephthalate)) and PET (polyterephthalic acid). Compared to elastic spandex, it offers advantages such as easy, comfortable, and durable elasticity, resulting in fabrics that are soft, crisp, and have good drape. It solves many problems associated with elastic spandex, including difficulty in dyeing, excessive elasticity, complex weaving, unstable fabric dimensions, and spandex aging during use.

[0018] Furthermore, the warp and weft yarns are woven using a 1 / 3 or 1 / 4 variation twill weave.

[0019] As described above, the warp and weft yarns are woven using a 1 / 3 or 1 / 4 twill weave. The yarns interweave and shrink, with one side of the fabric being the warp yarns, which has a light-absorbing and heat-generating effect, while the other side is mainly composed of weft yarns, which has a skin-friendly effect. Furthermore, due to the different degrees of dullness of the warp and weft yarns and the different yarn roughness caused by the process, the warp and weft yarns exhibit different colors after the fabric is dyed, thus achieving a double-sided, two-color effect.

[0020] Furthermore, the warp density is 160-175 threads / in, and the weft density is 100-115 threads / in.

[0021] Preferably, the warp density is 165-170 threads / in and the weft density is 105-110 threads / in.

[0022] As can be seen from the above description, the present invention uses a higher warp density, which makes the fabric feel softer and more comfortable to wear.

[0023] Another technical solution adopted in this invention is: the preparation method of the above-mentioned two-color double-sided fabric includes the following steps: using warp and weft yarns to weave a greige fabric, and the greige fabric is successively processed by fabric preparation, scouring, dyeing, dehydration, spreading and setting to obtain the two-color double-sided fabric.

[0024] As can be seen from the above description, the two-color double-sided fabric exhibits different colors after dyeing due to the different matting degrees of the warp and weft yarns and the different coarseness of the warp and weft yarns caused by the process. This achieves the effect of two-sided double-color.

[0025] Furthermore, the warp yarn range is 100~150D, and the weft yarn range is 100~150D.

[0026] As can be seen from the above description, in order to achieve both warmth and a good feel, the warp yarn range is controlled to be 100~150D and the weft yarn range is controlled to be 100~150D.

[0027] Embodiment 1 of the present invention is: a two-color, double-sided fabric, woven from warp and weft yarns. The warp yarn is 115D / 90F ATY yarn, and the weft yarn is 170D / 108F ATY yarn. The 115D / 90F ATY yarn is a composite of fully dull 75D / 72F polyester DTY quick-heat yarn and semi-dull 30D / 18F polyester T400 yarn. The 170D / 108F ATY yarn is a composite of semi-dull 75D / 36F polyester FDY yarn and semi-dull 75D / 72F polyester FDY yarn, twisted at 200T / M. The warp density is 167 ends / in, the weft density is 107 ends / in, and the weight is 190G±5Gsm. The warp and weft yarns are woven using a 1 / 3 variation twill weave structure. (See weave diagram). Figure 1 See the pattern diagram. Figure 2See the diagram. Figure 3 See the diagram of the fabric interlacing. Figure 4 and Figure 5 See photos of the front and back of the fabric. Figure 6 (The lighter-colored fabric is the reverse side, and the darker-colored fabric is the front side).

[0028] Embodiment 2 of the present invention is as follows: The only difference between Example 2 and Example 1 is that the warp density is 160 threads / in and the weft density is 100 threads / in, and the warp and weft yarns are woven using a 1 / 4 variation twill weave. See the weave diagram below. Figure 7 See the pattern diagram. Figure 8 See the diagram. Figure 9 See the diagram of the fabric interlacing. Figure 10 and Figure 11 .

[0029] Embodiment 3 of the present invention is as follows: The only difference between Example 3 and Example 1 is that the warp density is 175 threads / in and the weft density is 115 threads / in.

[0030] Embodiment four of the present invention is as follows: The materials used include: degreasing agent AFN, manufactured by Fujian Huafeng New Materials Co., Ltd.; Sindisperse CA-325 chelating dispersant, manufactured by Kunshan Mingjia; and high-temperature dispersing and leveling agent K-541, manufactured by Kunshan Mingjia.

[0031] A method for preparing a two-color, double-sided fabric includes the following steps: S1: The fabric is woven using the warp and weft yarns and weaving conditions described in Example 1.

[0032] S2: After the fabric is prepared, it is boiled; the preparation can be any existing preparation method; the specific boiling method is to put the fabric into warm water at 40℃, run for 7 minutes, add 3g / L degreasing agent AFN and 1g / L Sindisperse CA-325 chelating dispersant, heat to 95℃ at 3℃ / min and keep warm for 30 minutes, and then cool down to 60℃ at 1.5℃ / min.

[0033] S3: Dye the scouring and annealing fabric. The specific dyeing method is as follows: place the fabric in water at 30℃, add high-temperature dispersing and leveling agent K-541 in batches, adjust the pH value to 4.5, and then add the dye; then raise the temperature to 75℃, add degreasing agent AFN, raise the temperature to 110℃ at 1℃ / min and keep it at 7min, then raise the temperature to 130℃ at 1.2℃ / min and keep it at 20min; finally, lower the temperature to below 80℃ and drain the water to complete the dyeing; the dyeing formula is shown in Table 1.

[0034] Table 1

[0035] S4: The fabric is then dehydrated, spread out, and set in sequence; spreading out can be any existing spreading method; the setting temperature is 150℃, and the setting time is 30m / min.

[0036] Comparative Example 1 of the present invention is: The only difference between Comparative Example 1 and Example 4 is that the warp yarn in the fabric is 100D polyester lightweight mesh DTY yarn, the weft yarn is 150D polyester lightweight mesh DTY yarn, the weight is between 180G±5Gsm, and the network fastness of the lightweight mesh is 50%.

[0037] The heat-generating effect of the fabrics prepared in Example 4 and Comparative Example 1 was tested. Test method: A heat insulation film tester was used to test the initial temperature and the temperature at 20 minutes. The heat insulation film tester used a genuine Philips 150W infrared light source, in the near-infrared band, simulating the infrared radiation in sunlight, with a wavelength of 940mm. The temperature rise at 20 minutes was the difference between the temperature at 20 minutes and the initial temperature.

[0038] Table 2

[0039] As shown in Table 2, the double-sided, two-color fabric prepared by this invention has excellent light absorption and heat generation effects.

[0040] In summary, the two-color, double-sided fabric and its preparation method provided by this invention have the following advantages: 1. The warp yarn is set as the first ATY yarn and the weft yarn is set as the second ATY yarn. The ATY process gives the yarn a fluffy, breathable, soft, and cotton-like feel. At the same time, the high warp density makes the fabric feel softer and more comfortable to wear.

[0041] 2. Different matte finishes on the warp and weft yarns will cause differences in visual color; either the first ATY yarn or the second ATY yarn includes a DTY yarn, while the other is composed of FDY yarn; the different matte finishes on the warp and weft yarns, as well as the different yarn roughness caused by the process, result in the warp and weft yarns displaying different colors after the fabric is dyed, achieving a two-sided, two-color effect.

[0042] 3. The use of a composite of fast-heating yarn and elastic yarn to create ATY allows the yarn to simultaneously absorb light and generate heat while maintaining elasticity, resulting in a lighter and thinner fabric with better wearing comfort.

[0043] 4. The warp and weft yarns are woven with a 1 / 3 or 1 / 4 twill weave, so that one side of the fabric is made of warp yarns, which has the effect of absorbing light and generating heat, while the other side of the fabric is mainly made of weft yarns, which has a skin-friendly effect.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
