Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a sports fabric. Background Technology

[0002] In the field of children's sportswear, autumn and winter fabrics need to simultaneously address three core requirements: skin-friendly softness, efficient moisture wicking, and durable anti-static properties. Currently, most children's sportswear on the market uses polyester-spandex fabric. While polyester-spandex uses polyester with an irregular cross-section as its fiber raw material, enabling relatively fast sweat wicking and drying, the high modulus of polyester results in a relatively dry fabric with poor skin-friendly feel, and its anti-static effect is also unsatisfactory. Some children's sportswear uses nylon-spandex fabric. Although nylon-spandex is soft and skin-friendly, its poor moisture wicking properties make the inner layer sticky and cold after sweating, and its warmth retention is insufficient. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sports fabric that improves the fabric's ultra-soft texture, superconducting quick-drying properties, and antistatic performance through specific fiber materials and fabric structure.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a sports fabric with a double-layer structure, comprising: a moisture-wicking layer located on the outer layer, composed of nylon yarn with a core-sheath structure and a shaped cross-section, the core-sheath structure including a water-soluble polymer sheath and a nylon core layer, and the cross-section having grooves; and a skin-contact layer located on the inner layer, composed of brushed blended nylon yarn, the blended nylon yarn including ordinary nylon yarn and antistatic nylon yarn; the yarn of the moisture-wicking layer has a finer single fiber than the yarn of the skin-contact layer, and the single fiber fineness ratio is ≤1:2, so that sweat is unidirectionally guided from the skin-contact layer to the moisture-wicking layer.

[0006] The second technical solution is based on the first technical solution, wherein the irregular cross-section is gear-shaped and the number of grooves is ≥6.

[0007] The third technical solution is based on the second technical solution, wherein the moisture-wicking layer yarn is 100D / 288F DTY nylon yarn.

[0008] The fourth technical solution is based on the third technical solution, wherein the ordinary nylon yarn in the skin-adhesive layer blended yarn is 50D / 36F DTY nylon yarn.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the antistatic nylon yarn is a nylon yarn containing carbon black conductive masterbatch.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the skin-adhesive layer blended yarn also includes spandex yarn.

[0011] The seventh technical solution is based on the first technical solution, wherein the fabric is a 40G needle pitch double-sided knitted structure.

[0012] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0013] In the first technical solution and related embodiments, the fabric improves its ultra-soft texture, superconducting quick-drying properties, and antistatic performance by modifying the fiber composition and fabric structure. Borrowing from the capillary effect of glass (the process of the glass tube's opening narrowing from coarse to fine), the fabric's sweat is superconducted to the reverse side, allowing sweat from the skin-contact layer to quickly escape to the moisture-wicking layer, while simultaneously avoiding the possibility of static electricity and ensuring wearing comfort. Specifically, the moisture-wicking layer's core-sheath structure uses irregularly shaped cross-section nylon yarns to form grooves, improving sweat-wicking performance and achieving quick-drying. The skin-contact layer's blended nylon yarns, combined with a brushed finish, enhance skin-friendliness and softness. Antistatic nylon yarns improve antistatic performance. The moisture-wicking layer yarns have a finer single fiber than the skin-contact layer, with a single fiber fineness ratio ≤ 1:2, providing sufficient differential dynamics to achieve unidirectional sweat transfer and keep the skin-contact surface dry.

[0014] In the second technical solution and related embodiments, the nylon yarn is soft and skin-friendly, the gear-shaped cross-section increases the yarn surface area, and the grooves create a channeling space to improve sweat-wicking efficiency and enhance the fabric's quick-drying performance. This overcomes the characteristics of conventional polyester-spandex fabrics being dry and not soft enough against the skin.

[0015] In the third technical solution and related embodiments, the high-fiber count nylon yarn is ultra-fine denier nylon with a single fiber fineness (dpf) as low as 0.6, which is more than twice as fine as conventional nylon. This improves the softness and fineness of the fabric. The 40G high-needle double-sided yarn, combined with a special brushing process, creates a fine air layer formed by ultra-fine fibers on the surface, effectively blocking cold air from contacting the skin, while also providing far-infrared heating. These characteristics enable the fabric to provide excellent warmth when worn in autumn and winter, overcoming the problem of conventional low-fiber count nylon-spandex fabrics feeling cold in autumn and winter.

[0016] In the fourth technical solution and related embodiments, low-filament yarn provides good elasticity and resilience, and combined with napping treatment, enhances the fabric's skin-friendliness and comfort. Due to the difference in nylon filament count between the moisture-wicking layer and the skin-contact layer, the single-fiber fineness of the moisture-wicking layer yarn is less than that of the skin-contact layer yarn, with a fineness ratio ≤1:2, achieving a unidirectional transfer index greater than 4 for the fabric. This allows sweat from the skin-contact layer to be quickly wicked away to the moisture-wicking layer, preventing the skin-contact layer from feeling sticky.

[0017] In the fifth technical solution and related embodiments, carbon black conductive masterbatch effectively improves the antistatic properties of the fabric, reduces static electricity generation, and enhances wearing comfort.

[0018] In the sixth technical solution and related embodiments, spandex yarn is added to increase the elasticity of the fabric.

[0019] In the seventh technical solution and related embodiments, the double-knitted structure improves the elasticity and resilience of the fabric while maintaining excellent breathability and warmth retention. Attached Figure Description

[0029] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0030] See Figures 1 to 2 ,like Figure 1 As shown, a sports fabric has a double-layer structure, including a moisture-wicking layer 1 and a skin-contact layer 2. The fabric is a 40G gauge double-knit structure.

[0031] Moisture-wicking layer 1, such as Figure 2 As shown, it is located in the outer layer and is composed of nylon yarn with a core-sheath structure and irregular cross-section. The core-sheath structure includes a water-soluble polymer sheath layer 4 and a nylon core layer 3, and the cross-section has grooves 5. Specifically, the moisture-wicking layer 1 uses 100D / 288FDTY gear nylon yarn, which has a core-sheath structure. The sheath layer 4 is a water-soluble polymer PVA, the core layer 3 is nylon, and the cross-section is gear-shaped. The number of grooves 5 is ≥6.

[0032] Due to the limitations of nylon's physicochemical properties, it is difficult to achieve irregular cross-sections during the spinning stage. Therefore, a two-component approach is adopted, using a composite twin-screw spinning method, employing nylon chips and water-soluble polymer PVA chips respectively. First, two-component fibers are obtained through composite spinning technology. In this process, the water-soluble polymer serves as the sheath layer 4, and nylon as the core layer 3. The water-soluble nature allows the structure of the sheath layer 4 to be adjusted through water-soluble treatment during subsequent fabric preparation, thereby altering the overall properties of the fiber. Meanwhile, the nylon core layer 3 exhibits a gear-shaped cross-section.

[0033] In this embodiment, the nylon yarn is soft and skin-friendly, the gear-shaped cross-section increases the yarn surface area, and the grooves 5 create a channeling space to improve sweat-wicking efficiency and enhance the fabric's quick-drying performance. This overcomes the dryness and lack of softness associated with conventional polyester-spandex fabrics.

[0034] In this embodiment, the moisture-wicking layer 1 is made of 100D / 288F DTY nylon yarn. The high-filament (F) nylon yarn is ultra-fine denier nylon with a single fiber fineness (dpf) as low as 0.6, more than twice as fine as conventional nylon, improving the fabric's softness and smoothness. The 40G high-needle double-sided fabric, combined with a special brushing process, creates a fine air layer from the ultra-fine fibers on the surface, effectively blocking cold air from contacting the skin, while also providing far-infrared heating. These characteristics enable the fabric to provide excellent warmth during autumn and winter wear, overcoming the problem of feeling cold when wearing conventional low-filament nylon-spandex fabrics in autumn and winter.

[0035] The inner layer, skin-contact layer 2, is composed of brushed blended nylon yarns, including regular nylon yarn, antistatic nylon yarn, and spandex yarn. Specifically, skin-contact layer 2 uses blended nylon yarn, consisting of 50D / 36F regular nylon yarn, antistatic nylon yarn containing carbon black conductive masterbatch, and spandex yarn in a 90:5:5 ratio. The carbon black conductive masterbatch effectively improves the fabric's antistatic properties, reduces static electricity generation, and enhances wearing comfort. The addition of spandex yarn to skin-contact layer 2 increases the fabric's elasticity. Skin-contact layer 2 uses 50D / 36F regular nylon yarn; the low-filament yarn provides good elasticity and resilience, and combined with the brushed treatment, enhances the fabric's skin-friendly feel and comfort.

[0036] The yarn of the moisture-wicking layer 1 has a finer single fiber than that of the yarn of the skin-adhesive layer 2, and the fineness ratio is ≤1:2, so that sweat is guided unidirectionally from the skin-adhesive layer 2 to the moisture-wicking layer 1.

[0037] Due to the difference in nylon F-number between the moisture-wicking layer 1 and the skin-contact layer 2, the single-fiber fineness of the yarn in the moisture-wicking layer 1 is less than that in the skin-contact layer 2, and the single-fiber fineness ratio is ≤1:2, which allows the fabric to achieve a unidirectional transfer index greater than 4. This allows sweat from the skin-contact layer 2 to be quickly wicked away to the moisture-wicking layer 1, preventing sweat from becoming sticky in the skin-contact layer 2.

[0038] In this embodiment, the fabric structure is woven using a 40G double-knitting machine. The double-knitting structure improves the elasticity and resilience of the fabric while maintaining excellent breathability and warmth retention.

[0039] In this embodiment, the fabric improves its ultra-soft texture, superconducting quick-drying properties, and antistatic performance by modifying its fiber composition and fabric structure. Borrowing from the capillary effect of glass (the process of the glass tube narrowing from the bottom end), the fabric's sweat is superconducted to the reverse side, allowing sweat in the skin-contact layer 2 to be quickly wicked away to the moisture-wicking layer 1, while simultaneously avoiding the possibility of static electricity and ensuring wearing comfort. Specifically, the irregularly shaped cross-section nylon yarns in the core-sheath structure of the moisture-wicking layer 1 form grooves 5 to improve sweat wicking performance and achieve quick drying. The blended nylon yarns in the skin-contact layer 2 undergo a brushing treatment to improve skin-friendliness and softness. Antistatic nylon yarns containing conductive microparticles enhance antistatic performance. The yarn fineness of the moisture-wicking layer 1 is smaller than that of the skin-contact layer 2, with a fineness ratio ≤ 1:2, providing sufficient differential dynamics to achieve unidirectional sweat transfer and keep the skin-contact surface dry.

[0040] A method for preparing a sports fabric, comprising the following steps:

[0041] Step 1: Water-soluble polymer and nylon are melt-spun together to form a core-sheath structure nylon yarn with an irregular cross-section.

[0042] Step 2: Weave the moisture-wicking layer 1 with nylon yarn of irregular cross section, and weave the skin-adhesive layer 2 with blended nylon yarn containing conductive microparticles.

[0043] Step 3: Dissolve the water-soluble polymer in the fiber skin layer 4 to form grooves 5.

[0044] Step 4: Brushing, heat-pressing, dyeing, finishing, and shaping of the skin-adhesive layer 2.

[0045] The following is a detailed analysis of each specific step.

[0046] Step 1: Preparation of Nylon Yarn with Core-Sheath Structure and Irregular Cross-Section

[0047] 1.1 Selection of Fiber Materials

[0048] Skin layer 4 material: water-soluble polymer PVA slices

[0049] Core layer 3 material: ordinary nylon chips

[0050] 1.2 Melt spinning

[0051] Ordinary nylon chips and water-soluble polymer PVA chips are fed into a screw extruder for extrusion and melting. The melting temperature of ordinary nylon chips is 220℃-240℃, and the melting temperature of water-soluble polymer PVA chips is also 260℃-280℃.

[0052] The weight ratio of ordinary nylon chips to water-soluble PVA chips was 80:20.

[0053] The molten chips are spun into POY yarn semi-finished products by passing them through a twin-screw gear spinneret.

[0054] 1.3 Post-processing

[0055] The POY bobbin semi-finished product is subjected to stretching, winding and elastic development treatment to finally obtain 100D / 288F DTY gear nylon yarn.

[0056] Step 2: Weaving the fabric structure

[0057] 2.1 Yarn Selection

[0058] Moisture-wicking layer 1 yarn: 100D / 288F DTY gear nylon yarn prepared in step 1.

[0059] Skin-adhesive layer 2 yarn: blended nylon yarn, including 90% 50D / 36F ordinary nylon DTY raw yarn and 5%-10% antistatic nylon raw yarn (derived from Beirut Corporation of Japan, carbon black conductive masterbatch added to the nylon yarn), or 5% spandex yarn added as needed.

[0060] 2.2 Weaving Process

[0061] It is woven using a 40G high-needle double-sided knitting structure.

[0062] The skin-contact layer 2 (reverse side) is made of blended nylon yarn, while the moisture-wicking layer 1 (front side) is made of 100D / 288F DTY gear nylon yarn.

[0063] Step 3: Water-soluble processing

[0064] The pre-treated, degreased fabric is then passed through an overflow dyeing machine at 100°C for 25-30 minutes. 5-10 g / L of NaOH is added, causing water-soluble PVA chips to dissolve through precipitation, thus forming a gear-like microporous structure in the moisture-wicking layer 1. In this embodiment, a certain amount of alkali is added to the aqueous solution to accelerate the dissolution rate of PVA.

[0065] Step 4: Skin-adhesive layer 2: Brushing, ironing, dyeing, finishing, and shaping of the fabric.

[0066] 4.1 Dyeing process

[0067] The process employs a multi-stage dyeing, finishing, and softening process, with the dyeing temperature for acid dyes controlled at 90-100℃ and the dyeing time controlled at 40-50 minutes.

[0068] The dyeing process employs a micro-pressure dyeing vat (<0.2MPa vat pressure control), a gradient temperature control curve (±1.5℃ / min precise rise and fall), and a 9-stage water tank gentle wash combined with nano-emulsification oil removal technology to allow the fiber fabric to fully absorb water and undergo heat shrinkage to achieve a fluffy and full state.

[0069] 4.2 Brushing and Polishing Process

[0070] The dyed skin-adhesive layer 2 is treated with a Lafer brushing machine imported from Italy.

[0071] The pressure roller is selected from 800-mesh ceramic sand rollers. The pressure of the pressure roller is controlled at 8-9 kg, and the speed is controlled at 850-900 rpm.

[0072] Comb away loose hairs, and then trim away long hairs.

[0073] The process involves heat treatment using a single-roller heat treatment machine on the super soft fleece, followed by drying via a heated roller. The temperature of the heated roller is set to 180℃-190℃, the fleece travel speed is controlled at 28-32m / min, and the drying time is approximately 1.5-2.5 minutes.

[0074] In this embodiment, despite the use of a special brushing process, the breathability remains excellent and is not compromised by the processing, ensuring wearing comfort.

[0075] 4.3 Post-processing softening

[0076] The finishing process was carried out using a plant-based hydrophilic finishing agent (30% castor oil derivative).

[0077] Use a setting machine to process at 150℃ for 3 minutes.

[0078] In this embodiment, during the raw yarn preparation stage, a core-sheath structure yarn is prepared by bicomponent melt spinning, laying the foundation for the subsequent formation of grooves 5; during the weaving stage, the moisture-wicking layer 1 and the skin-adhering layer 2 are woven to achieve a double-layer structure of the fabric; through water-soluble treatment, water-soluble polymers are dissolved to form grooves 5, enhancing the sweat-wicking performance of the moisture-wicking layer 1; in the final napping and setting stage, napping and calendering treatments improve the skin-friendliness and softness of the skin-adhering layer 2, while setting treatments maintain the stability and durability of the fabric.
