Description

Technical Field

[0001] This application relates to the field of clothing fabric technology, specifically to a heat-insulating and moisture-wicking fabric and its preparation method, and clothing. Background Technology

[0002] Currently, with the improvement of people's living standards, various sports are becoming increasingly popular, leading to higher and higher requirements for clothing. Among them, the marathon, as a high-intensity endurance event, places extremely high demands on the performance of sportswear.

[0003] Currently, most marathon runners wear sports vests. These vests typically utilize quick-drying fabrics, seamless construction, and lightweight design to enhance comfort and performance. For example, they often incorporate evenly spaced mesh vents in prominent areas like the armpits and back to improve sweat-wicking properties.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Sports vests in related technologies can generally only achieve single moisture absorption or breathability, making it difficult to simultaneously meet the dual dynamic needs of heat insulation and rapid sweat wicking during exercise. At the same time, the ventilation holes of sports vests are generally formed through finishing processes, such as laser cutting or stamping. This not only damages the fiber structure and affects the durability of the fabric, but may also cause problems such as scorched edges at the edges of the holes, making them prone to pilling or snagging with long-term use.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a heat-insulating and moisture-wicking fabric and its preparation method, as well as clothing, which can simultaneously meet the dual dynamic requirements of heat insulation and rapid sweat wicking, thereby improving the user's wearing comfort.

[0009] In some embodiments, the heat-insulating and moisture-wicking fabric includes a skin-friendly inner surface and an outer surface. The skin-friendly inner surface comprises a warp-knitted fabric of fully stretched yarn fibers, wherein the cross-section of the fully stretched yarn fibers is polygonal and its interior has a hollow structure, the hollow structure trapping static air; the outer surface comprises a warp-knitted fabric of polyester fibers; a plurality of first regions and a plurality of second regions are further provided on the skin-friendly inner surface, the first regions being warp-knitted with a first jacquard structure, and the second regions being warp-knitted with a second jacquard structure; wherein the mesh aperture of the first jacquard structure is larger than the mesh aperture of the second jacquard structure; and the thickness of the first jacquard structure is smaller than the thickness of the second jacquard structure.

[0010] In some embodiments, the fiber diameter of the skin-friendly inner surface is larger than the fiber diameter of the outer surface of the garment.

[0011] In some embodiments, the linear density of the skin-friendly inner surface is less than the linear density of the outer surface of the garment.

[0012] In some embodiments, the cross-section of the fully drawn filament is octagonal.

[0013] In some embodiments, the hollow structure has a hollowness of 17%.

[0014] In some embodiments, the method for preparing the heat-insulating and moisture-wicking fabric uses a warp knitting machine with a front knitting comb GB2 and a Jacquard comb JB1, respectively; the preparation method includes the following steps:

[0015] The Jacquard comb JB1 is inserted into the fully stretched yarn fibers in a full-thread manner to weave a basic 1-0 / 1-2 structure. The offset movement of the Jacquard comb JB1 is controlled by the Jacquard jacquard device to weave a skin-friendly inner surface with multiple first regions and multiple second regions.

[0016] The chain comb GB2 is inserted into the polyester fiber in a full-through manner to weave a basic 1-0 / 0-1 structure to form the outer surface of the garment;

[0017] The raw fabric is obtained by weaving a skin-friendly inner surface and an outer surface.

[0018] The prepared greige fabric is inspected and finished to obtain the heat-insulating and moisture-wicking fabric.

[0019] In some embodiments, the chain comb GB2 is formed by open chain braiding and is braided in the same direction as the Jacquard comb JB1.

[0020] In some embodiments, the warp feed rate of the chain braiding comb GB2 is 700mm / rack to 900mm / rack.

[0021] In some embodiments, the Jacquard comb JB1 consists of two half-size combs, one with a thread and one without, and the other with one without and one with a thread. The warp feed rate of the Jacquard comb JB1 is 1800mm / rack to 2600mm / rack.

[0022] In some embodiments, the fabric of the garment is the heat-insulating and moisture-wicking fabric described in the foregoing embodiments, or the heat-insulating and moisture-wicking fabric prepared by the heat-insulating and moisture-wicking surface preparation method described in the foregoing embodiments; wherein, the garment includes a sports vest or a sports short-sleeved shirt, the sports vest or sports short-sleeved shirt being a one-piece cut with its side seams located on the back.

[0023] The heat-insulating and moisture-wicking fabric, its preparation method, and the garment provided in this disclosure can achieve the following technical effects:

[0024] The skin-friendly inner surface comprises a warp-knitted fabric of fully stretched yarn fibers, while the outer surface comprises a warp-knitted fabric of polyester fibers. The skin-friendly inner surface also features multiple first zones and multiple second zones. The first zones are warp-knitted with a first jacquard structure, and the second zones with a second jacquard structure. This allows the jacquard structure to quickly absorb sweat from the skin surface, keeping the skin dry. The outer surface rapidly absorbs sweat from the skin-friendly inner surface and diffuses it over a large area, thereby greatly improving evaporation efficiency.

[0025] Based on this, the mesh diameter of the first jacquard structure is larger than that of the second jacquard structure, and the thickness of the first jacquard structure is smaller than that of the second jacquard structure. Furthermore, the cross-section of the fully drawn yarn is polygonal, and its interior is a hollow structure that traps static air. This allows for a zoned functional design, with the mesh of the first jacquard structure accelerating moisture wicking and heat dissipation, while the mesh of the second jacquard structure provides insulation through a static air layer. This simultaneously addresses the dual dynamic needs of heat insulation and rapid perspiration wicking, improving the user's wearing comfort.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

Those skilled in the art can understand the specific meaning of these terms in the embodiments of this disclosure according to the specific circumstances.

[0033] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts.

[0034] Unless otherwise stated, the term "multiple" means two or more.

[0035] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0036] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Most current quick-drying clothing products use a uniform mesh design or simple localized adjustments, such as adding ventilation holes in obvious areas like the armpits and back. However, increasing the number of ventilation holes or reducing fabric coverage can affect heat insulation and warmth retention, while also reducing UV protection; conversely, decreasing the number of ventilation holes or increasing fabric coverage can hinder sweat evaporation.

[0039] Therefore, this disclosure provides a heat-insulating and moisture-wicking fabric, including a skin-friendly inner surface and an outer surface. The skin-friendly inner surface comprises a warp-knitted fabric of fully drawn yarn fibers, wherein the cross-section of the fully drawn yarn fibers is polygonal and its interior has a hollow structure, which traps static air. The outer surface comprises a warp-knitted fabric of polyester fibers. The skin-friendly inner surface also has multiple first regions and multiple second regions. The first regions are warp-knitted with a first jacquard structure, and the second regions are warp-knitted with a second jacquard structure. The mesh size of the first jacquard structure is larger than that of the second jacquard structure, and the thickness of the first jacquard structure is smaller than that of the second jacquard structure.

[0040] The heat-insulating and moisture-wicking fabric provided in this embodiment includes a skin-friendly inner surface made of warp-knitted fabric of fully stretched yarn fibers, and an outer surface made of warp-knitted fabric of polyester fibers. The skin-friendly inner surface also has multiple first regions and multiple second regions. The first regions are warp-knitted with a first jacquard structure, and the second regions are warp-knitted with a second jacquard structure. This allows the jacquard structure to quickly absorb sweat from the skin surface, keeping the skin dry. The outer surface can quickly absorb sweat from the skin-friendly inner surface and diffuse it over a large area, thereby greatly improving evaporation efficiency.

[0041] Based on this, the mesh diameter of the first jacquard structure is larger than that of the second jacquard structure, and the thickness of the first jacquard structure is smaller than that of the second jacquard structure. Furthermore, the cross-section of the fully drawn yarn is polygonal, and its interior is a hollow structure that traps static air. This allows for a zoned functional design, with the mesh of the first jacquard structure accelerating moisture wicking and heat dissipation, while the mesh of the second jacquard structure provides insulation through a static air layer. This simultaneously addresses the dual dynamic needs of heat insulation and rapid perspiration wicking, improving the user's wearing comfort.

[0042] In this embodiment, the fully drawn yarn has a strong wicking effect, which can quickly absorb sweat from the skin surface, while the polyester fiber can quickly absorb the sweat absorbed by the fully drawn yarn and diffuse it over a large area. Combined with the mesh structure, it can greatly improve the evaporation efficiency of sweat.

[0043] In this embodiment of the disclosure, the heat-insulating and moisture-wicking fabric is a single-layer fabric, wherein the front side of the heat-insulating and moisture-wicking fabric is the outer surface of the garment, and the back side of the heat-insulating and moisture-wicking fabric is the skin-friendly inner surface.

[0044] In some embodiments, the fiber diameter on the skin-friendly inner surface is larger than the fiber diameter on the outer surface of the garment.

[0045] The difference in hygroscopicity between the inner and outer layers of a fabric can induce a differential capillary effect. In this embodiment, the fiber diameter of the skin-friendly inner surface is larger than that of the outer surface, specifically, the diameter of the fully drawn yarn is larger than that of the polyester fiber. This difference in hygroscopicity between the skin-friendly inner surface and the outer surface creates a differential capillary effect, allowing sweat to flow from the skin-friendly inner surface to the outer surface.

[0046] In some embodiments, the linear density of the skin-friendly inner surface is less than the linear density of the outer surface of the garment.

[0047] The difference in linear density between the inner and outer layers of a fabric creates a pressure difference. In this embodiment, because the fiber diameter of the skin-friendly inner surface is larger than that of the outer surface, the linear density of the skin-friendly inner surface is smaller than that of the outer surface, given the same surface area. This creates a pressure difference between the skin-friendly inner surface and the outer surface, thereby forcing sweat to flow from the skin-friendly inner surface to the outer surface.

[0048] In some specific embodiments, the fully stretched yarn fiber in the skin-friendly inner surface is 50D24F, and the polyester fiber in the outer surface is 30D24F.

[0049] In some embodiments, the cross-section of the fully drawn filament fiber is octagonal.

[0050] In this embodiment, the surface of the fully drawn yarn is relatively smooth and has an octagonal cross-sectional structure. When the fully drawn yarn forms a skin-friendly inner surface, it can create a rapid hydrophobic path, thereby further ensuring that sweat flows from the skin-friendly inner surface to the outer surface of the garment.

[0051] In some embodiments, the hollowness of the hollow structure is 17%.

[0052] In this embodiment, the hollow, fully stretched filament ensures the thermal insulation performance, i.e., heat preservation performance, of the skin-friendly inner surface. Here, the static air sealed inside the hollow structure acts as a good thermal insulator, effectively preventing the rapid loss of body heat when at rest after exercise.

[0053] In this embodiment, during the application of the skin-friendly inner surface and the outer surface, the polyester fibers of the outer surface utilize the large capillary effect and hydrophilic groups generated by its microfiber structure. This allows the outer surface to powerfully lock in sweat and significantly expand it to accelerate evaporation. This creates a "repellent inside, hydrophilic outside" unidirectional moisture-wicking effect, keeping the skin dry for a long time.

[0054] In this embodiment, a plurality of first regions and a plurality of second regions are further provided on the skin-friendly inner surface. The first regions are warp-knitted with a first jacquard structure, which has a larger mesh size and a thinner thickness. This maximizes breathability and perspiration wicking efficiency. This first region is used in areas with high perspiration rates, such as the back and underarms. The second regions are warp-knitted with a second jacquard structure, which has a smaller mesh size and a thicker thickness. This retains an air layer, achieving a heat insulation effect. This second region is used in areas with high perspiration rates, such as the chest and abdomen.

[0055] Therefore, through the designed Jacquard structure, the body temperature is regulated according to the body's condition. When needed (such as during exercise), it can act as a heat dissipation channel to efficiently expel hot and humid air, while ensuring that body temperature is not lost too quickly. In this way, a dynamic adaptive heat insulation system is formed.

[0056] This disclosure also provides a method for preparing a heat-insulating and moisture-wicking fabric, wherein the front and rear knitting machines of the warp knitting machine are respectively a chain comb GB2 and a Jacquard comb JB1; the preparation method includes the following steps:

[0057] Jacquard comb JB1 is inserted into fully stretched yarn fibers in a full-thread manner to weave a basic 1-0 / 1-2 structure. The offset movement of Jacquard comb JB1 is controlled by Jacquard jacquard device to weave a skin-friendly inner surface with multiple first zones and multiple second zones.

[0058] The chain comb GB2 is inserted into the polyester fiber in a full-through manner to weave a basic 1-0 / 0-1 structure to form the outer layer of the garment;

[0059] The raw fabric is obtained by weaving a skin-friendly inner surface and an outer surface.

[0060] The resulting greige fabric is inspected and finished to obtain a heat-insulating and moisture-wicking fabric.

[0061] In this embodiment of the disclosure, the warp knitting machine is an RSJ5 / 1 type warp knitting machine with an E28 needles / inch.

[0062] In this embodiment, fully drawn yarn is used as the raw material for Jacquard comb JB1, and polyester fiber is used as the raw material for braided comb GB2. The raw materials are placed on a bobbin holder and warped on a warping machine according to process requirements to ensure uniform yarn tension and consistent yarn size.

[0063] Jacquard comb JB1 is inserted into fully stretched yarn fibers in a full-through manner to weave a basic 1-0 / 1-2 structure; chain comb GB2 is inserted into polyester fibers in a full-through manner to weave a basic 1-0 / 0-1 structure; then, according to the pre-designed pattern, the offset movement of the JB1 comb is controlled by the Jacquard device to weave positioning areas with different mesh sizes and thicknesses on the fabric.

[0064] The woven fabric undergoes quality inspection. After passing the inspection, the fabric is refined, dyed, treated with a hydrophilic softening finish, and then set and dried. The dyeing process can be tailored to specific needs; for example, a hydrophilic softening finish can enhance the absorbency and release properties of hydrophilic polyester.

[0065] After the fabric is shaped and dried, it is cut to make different garments.

[0066] Here, by employing a Jacquard weaving device, the offset of each Jacquard guide needle can be controlled to form patterns. Changing the pattern only requires modifying the computer program, without replacing machine parts. This makes pattern changes easier, allows for a wider variety of patterns, and enables the design of mesh sizes based on human perspiration patterns.

[0067] In some embodiments, the chain braiding comb GB2 is formed by open chain braiding and is braided in the same direction as the Jacquard comb JB1. This ensures that the fabric of the Jacquard comb JB1 is always on the reverse side of the process, while the fabric of the chain braiding comb GB2 is always on the forward side of the process.

[0068] In some embodiments, the warp feed rate of the chain braiding comb GB2 is 700mm / rack to 900mm / rack.

[0069] In some embodiments, the Jacquard comb JB1 consists of two half-size combs, one with a thread and one without, and the other with one without and one with a thread. The warp feed rate of the Jacquard comb JB1 is 1800mm / rack to 2600mm / rack.

[0070] In this embodiment, since the diameter of the polyester fiber yarn in the chain comb GB2 is smaller than that of the fully drawn filament fiber yarn in the Jacquard comb JB1, the feed rate of the chain comb GB2 can be appropriately increased to ensure that the yarn in the chain comb GB2 has a good coverage effect on the yarn in the Jacquard comb JB1 on the process side.

[0071] In some embodiments, the fabric density is: 13-15 rows / cm in the warp and 26-30 rows / cm in the weft.

[0072] In some embodiments, the finished density of the fabric is: 15-17 rows / cm in the warp and 28-32 rows / cm in the weft.

[0073] This disclosure also provides a garment, the fabric of which is the heat-insulating and moisture-wicking fabric described in the foregoing embodiments, or a heat-insulating and moisture-wicking fabric prepared by the heat-insulating and moisture-wicking surface preparation method described in the foregoing embodiments.

[0074] The specific structure of the garment is as described in the above embodiments. Since the garment adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0075] In some embodiments, the garment includes a sports vest or a sports short-sleeved shirt, wherein, in the case of a sports vest, the sports vest is a one-piece cut with its side seams located on the back.

[0076] Combination Figure 1 and Figure 2 As shown in this embodiment, the sports vest is cut in one piece, which ensures the integrity of the sports vest. At the same time, the side seams are located on the back of the sports vest, that is, the cut surface is only on the back of the sports vest, which effectively avoids friction between the side seams and the armpits and arms, making the user more comfortable to wear and greatly improving the comfort and freedom of movement during exercise.

[0077] In this embodiment, the skin-contact side uses fully stretched yarn fibers, which can quickly absorb sweat from the skin surface and keep the skin dry. The outer layer uses polyester fibers, which can quickly absorb and diffuse moisture over a large area, and the mesh structure greatly improves evaporation efficiency. The design is tailored to high-perspiration areas such as the back and armpits, and low-perspiration areas such as the chest and abdomen. In high-perspiration areas, a large-mesh, thinner jacquard structure is designed to maximize breathability and sweat-wicking efficiency; in low-perspiration areas, a small-mesh, thicker jacquard structure is designed to retain an air layer and achieve heat insulation.

[0078] The present invention will be further explained and illustrated below with reference to embodiments.

[0079] Example 1

[0080] This embodiment 1 provides a heat-insulating and moisture-wicking fabric, the preparation method of which is as follows:

[0081] Fiber raw materials: The skin-friendly inner surface uses 50D / 24F fully stretched yarn fiber, accounting for approximately 72% to 76%; the outer surface uses 40D / 24F polyester fiber, accounting for approximately 24% to 28%.

[0082] The warp feed and on-machine density of the two jacquard combs were determined, and the jacquard pattern was designed. The upper back and armpit areas of the vest's back piece were designed with a sparse, large-mesh pattern, while the chest and lower abdomen areas were designed with a dense, small-mesh pattern. Subsequent finishing processes included dyeing and setting to meet the finished product requirements. Specifically, the warp feed of the JB1 jacquard comb was 2240 mm / rack, and the warp feed of the GB2 chain braiding comb was 800 mm / rack; the fabric on-machine density was: 14 rows / cm in warp direction and 28 rows / cm in weft direction.

[0083] Example 2

[0084] This embodiment 2 provides a heat-insulating and moisture-wicking fabric. The difference between this embodiment and embodiment 1 is that the skin-friendly inner surface uses 60D / 24F fully stretched yarn fiber, accounting for approximately 63% to 70%; the outer surface uses 30D / 24F polyester fiber, accounting for approximately 30% to 37%. Everything else is the same as in embodiment 1.

[0085] Example 3

[0086] This embodiment 3 provides a heat-insulating and moisture-wicking fabric. The difference between this embodiment and embodiment 1 is that the skin-friendly inner surface uses 70D / 24F fully stretched yarn fiber, accounting for approximately 63% to 70%; the outer surface uses 30D / 24F polyester fiber, accounting for approximately 30% to 37%. Everything else is the same as in embodiment 1.

[0087] Comparing Examples 1 to 3, it is evident that the finer the fully stretched filament fibers on the skin-friendly inner surface, the denser the resulting fabric structure, which reduces breathability. However, finer fibers create a more uniform microporous structure, promoting water vapor diffusion and improving moisture permeability. Excessive polyester fiber content can negatively impact the fabric's breathability and moisture permeability, but appropriately increasing the polyester fiber content can improve the fabric's elasticity and abrasion resistance.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments. Embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from its scope. The scope of the present disclosure is limited only by the appended claims.
