Description

Technical Field

[0001] This utility model relates to the field of textiles, and more specifically, to a composite breathable fabric. Background Technology

[0002] Most multi-layer composite fabrics currently on the market use different yarn layers to create breathable composite fabrics with moisture-wicking, soft, and comfortable feel. However, the breathability of multi-layer composite fabrics is easily reduced due to the overlapping of individual layers. In addition, in order to save costs, multi-layer composite fabrics are usually connected by gluing during the composite process. The adhesive fills the air pores on the composite fabric, resulting in poor breathability of this type of composite fabric. Utility Model Content

[0003] The purpose of this invention is to provide a composite breathable fabric to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite breathable fabric, comprising a base fabric and a face fabric, wherein the base fabric is provided with several rectangular arrays of breathable grooves and protrusions, and each protrusion is provided with four breathable grooves symmetrically distributed in pairs around its periphery. A hot melt adhesive layer is provided at the edge of each breathable groove on the base fabric, and the base fabric and the face fabric are fixedly connected by the hot melt adhesive layer.

[0005] By incorporating breathable channels, only the outer fabric acts as a barrier at these channels, creating a single-layer structure. This significantly improves the breathability of the composite breathable fabric. Furthermore, using a hot-melt adhesive layer to bond the edges of the breathable channels to the outer fabric avoids completely coating the interface between the base fabric and the outer fabric, further enhancing breathability. This also secures the edges of the breathable channels, ensuring the connection strength between the base fabric and the outer fabric while preventing tearing due to stress concentration at the corners of the breathable channels under stress, thus guaranteeing the fabric's usability. Additionally, the raised sections create multiple inward protrusions in the base fabric, increasing airflow channels when used in garments, thereby achieving high breathability.

[0006] Preferably, the absorbency of the face fabric is greater than that of the base fabric.

[0007] Because the outer fabric is more absorbent than the base fabric, sweat can be quickly absorbed by the outer fabric through the base fabric when you sweat, keeping the inside relatively dry and improving comfort.

[0008] Preferably, the base fabric is woven from polyester low-elasticity yarn, and the yarn count of the polyester low-elasticity yarn is 60S-80S.

[0009] Because the base fabric is woven with 60S-80S polyester low-elasticity yarn, it can increase the strength of the base fabric and have a certain tensile properties. In addition, the yarn of this count is relatively fine, making the base fabric softer, thinner and more comfortable to the touch.

[0010] Preferably, the ventilation groove can be circular, rectangular, rhomboid, or regular hexagonal.

[0011] Preferably, the fabric is woven from warp and weft yarns, with a bamboo charcoal fiber filament provided every 5-10 warp yarns and a bamboo charcoal fiber filament provided every 5-10 weft yarns.

[0012] By incorporating bamboo charcoal fiber filaments, the fabric gains excellent moisture absorption, breathability, and antibacterial properties, further enhancing its breathability.

[0013] Preferably, both the warp and weft yarns are made of linen-cotton composite yarn, which includes an inner core and a covering yarn spirally wound on the inner core. The inner core is made of twisted linen fibers, and the covering yarn is made of twisted cotton fibers.

[0014] Because hemp fiber has excellent moisture absorption and wicking properties as well as breathability, it can improve the breathability of the fabric. Furthermore, the inner core is wrapped with cotton fiber, and the hemp fiber is combined with cotton fiber to make hemp-cotton composite yarn, which greatly improves the breathability of the fabric.

[0015] Preferably, the yarn count of the linen-cotton composite yarn is 45S-60S.

[0016] Because the yarn count of the linen-cotton composite yarn is 45S-60S, the yarn is coarser than the polyester low-elasticity yarn of the base fabric, so the outer fabric is thicker than the base fabric, ensuring the wearer's needs.

[0017] In summary, this utility model has the following beneficial effects:

[0018] This invention improves the breathability of the composite breathable fabric by incorporating breathable grooves, where only the outer fabric acts as a barrier, creating a single-layer structure. Furthermore, the use of a hot-melt adhesive layer to bond the edges of the breathable grooves to the outer fabric avoids completely coating the interface between the base fabric and the outer fabric, further enhancing breathability. This also secures the edges of the breathable grooves, ensuring the connection strength between the base fabric and the outer fabric while preventing tearing due to stress concentration at the corners of the breathable grooves under stress, thus guaranteeing the fabric's usability. Additionally, the raised sections create multiple inward protrusions in the base fabric, increasing airflow channels when used in garments, thereby achieving high breathability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 and Figure 2 As shown, a composite breathable fabric includes a base fabric 2 and an outer fabric 1. The water absorption of the outer fabric 1 is greater than that of the base fabric 2. The base fabric 2 is woven from polyester low-elastic yarn, which can increase the strength of the base fabric 2 and provide a certain degree of tensile properties. The yarn count of the polyester low-elastic yarn is 60S-80S, which makes the polyester low-elastic yarn relatively fine. Therefore, the base fabric 2 can be softer, thinner, and more comfortable to the touch.

[0026] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the outer fabric 1 is woven from warp and weft yarns, with a bamboo charcoal fiber filament 6 placed every 5-10 warp yarns and a bamboo charcoal fiber filament 6 placed every 5-10 weft yarns. Bamboo charcoal fiber has excellent moisture absorption, breathability, and antibacterial properties. Both the warp and weft yarns are made of linen-cotton composite yarn 5. The linen-cotton composite yarn 5 includes an inner core 51 and a covering yarn 52 spirally wound on the inner core 51. The inner core 51 is made of twisted linen fiber, and the covering yarn 52 is made of twisted cotton fiber. Linen fiber has good moisture absorption and wicking properties as well as breathability. Cotton fiber has good moisture absorption and breathability. The combination of linen fiber and cotton fiber to make linen-cotton composite yarn 5 greatly improves the breathability of the outer fabric 1. The yarn count of the linen-cotton composite yarn 5 is 45S-60S, which means that the linen-cotton composite yarn 5 is coarser than the polyester low-elasticity yarn of the base fabric 2. Therefore, the outer fabric 1 is thicker than the base fabric 2, ensuring the wearing needs.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, the base fabric 2 has several rectangular arrays of breathable grooves 21 and protrusions 3. The breathable grooves 21 can be circular, rectangular, rhomboid, or regular hexagonal. Each protrusion 3 has four symmetrically distributed breathable grooves 21 around its periphery. A hot melt adhesive layer 4 is provided at the edge of each breathable groove 21 on the base fabric 2. The base fabric 2 and the face fabric 1 are fixedly connected by the hot melt adhesive layer 4. That is, only the face fabric 1 acts as a barrier at the breathable groove 21 position, forming a single-layer structure, which can significantly improve the breathability of the composite breathable fabric. Moreover, the hot melt adhesive layer 4 is used to protect the edges of the breathable grooves 21. The base fabric 2 and the outer fabric 1 are glued together, which can achieve the gluing effect without completely coating the connecting surface of the base fabric 2 and the outer fabric 1, further improving the breathability. It can also fix the edge of the breathable groove 21, ensuring the connection strength between the base fabric 2 and the outer fabric 1, and preventing the base fabric 2 from tearing due to stress concentration at the corners of the breathable groove 21 when under stress, thus ensuring the normal use of the fabric. In addition, under the action of the protrusion 3, the base fabric 2 presents multiple protrusions inward, which can increase the flow channels when it is made into a garment, thereby achieving high breathability of the fabric.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
