Description

Technical Field

[0001] This utility model relates to the field of fabric design technology, and in particular to a lightweight abrasion-resistant fabric for outdoor equipment. Background Technology

[0002] Outdoor gear fabrics not only need to withstand the intense friction from complex terrain and vegetation, but also need to effectively manage the sweat and heat generated by the human body during high-intensity exercise to keep the wearer dry, comfortable and warm, while avoiding odor problems caused by sweat and bacterial growth.

[0003] The existing utility model patent, such as CN214522481U entitled "Abrasion-resistant Fabric", discloses abrasion-resistant layer and CORDURA surface layer. The CORDURA surface layer is laminated to the lower surface of the abrasion-resistant layer. The abrasion-resistant layer is warp-knitted from abrasion-resistant warp and abrasion-resistant weft. The abrasion-resistant warp includes abrasion-resistant composite yarn and skin-friendly yarn. The abrasion-resistant composite yarn and the skin-friendly yarn are arranged alternately. The skin-friendly yarn is one of soybean fiber yarn, lyocell fiber yarn, and Rio bamboo fiber yarn.

[0004] Similar to the above-mentioned fabric, good abrasion resistance is achieved through the superposition of multiple layers. However, the superposition of multiple layers inevitably leads to the fabric becoming thicker, heavier, and harder, and the functional layers are easily separated. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight abrasion-resistant fabric for outdoor equipment, which solves the technical problem of poor breathability and sweat-wicking performance of existing abrasion-resistant fabrics.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A lightweight abrasion-resistant fabric for outdoor gear includes a contact layer, a middle layer, and a comfort layer. The contact layer is located on one side of the middle layer, and the comfort layer is located on the side of the middle layer opposite to the contact layer. The contact layer, middle layer, and comfort layer are integrally formed by a weaving process. The contact layer has a plurality of protrusions and a plurality of recesses arranged alternately with the protrusions. The middle layer has a plurality of vertically arranged breathable channels. The comfort layer contains an antibacterial substance.

[0008] The present invention is further configured such that: the contact layer is woven from thermotropic liquid crystal polymer fibers and high-strength nylon, and the protrusions and recesses are formed by weft knitting jacquard technology.

[0009] The present invention is further configured such that: all of the several breathable channels are diamond-shaped channels, and the opening size of the several of the breathable channels facing the comfort layer is smaller than the opening size facing the contact layer.

[0010] The present invention is further configured such that: the material of the intermediate layer is aramid fiber, and the intermediate layer is formed by warp knitting interval technology.

[0011] The present invention is further configured such that: the material of the comfort layer is a mixture of polypropylene and nylon fibers, and the antibacterial substance is silver ions.

[0012] The present invention is further configured such that: the thickness of the contact layer is 0.15-0.35 mm, the thickness of the intermediate layer is 0.8-1.2 mm, and the thickness of the comfort layer is 0.1-0.25 mm.

[0013] Compared to the beneficial effects achieved by existing technologies:

[0014] The fabric of this application greatly improves surface abrasion resistance through the concave-convex design of the contact layer; the vertical breathable channels in the middle layer work together with the surface pores to create an efficient moisture-wicking and quick-drying system, allowing the fabric to quickly wick away sweat and keep the wearer dry; the built-in antibacterial substances directly inhibit odor generation from the source; at the same time, the one-piece molding weaving process ensures the overall lightweight and structural stability of the fabric while integrating all these functions, meeting the stringent requirements of high-end outdoor equipment for protection, comfort, and lightness.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] Reference Figures 1-3This application discloses a lightweight abrasion-resistant fabric for outdoor gear, comprising a contact layer 1, a middle layer 2, and a comfort layer 3. The contact layer 1 is located on one side of the middle layer 2, and the comfort layer 3 is located on the side of the middle layer 2 opposite to the contact layer 1. The contact layer 1, middle layer 2, and comfort layer 3 are woven simultaneously using an integrated molding knitting process on a double-needle bed warp knitting machine. The thickness of the contact layer 1 is 0.15–0.35 mm, the thickness of the middle layer 2 is 0.8–1.2 mm, and the thickness of the comfort layer 3 is 0.1–0.25 mm. This integrated molding process avoids subsequent lamination or bonding processes, effectively ensuring the overall structural stability of the fabric, eliminating the risk of delamination during use, and minimizing the use of adhesives, thus achieving extreme lightweighting of the fabric.

[0022] like Figure 2 As shown, the contact layer 1 has a plurality of protrusions 4 and a plurality of recesses 5 arranged alternately with the protrusions 4. This layer is made of 70% thermotropic liquid crystal polymer (TLCP) fiber and 30% high-strength nylon fiber as raw materials, and is woven into a preset concave-convex structure using weft knitting jacquard technology of a computer jacquard weft knitting machine. The extremely high modulus and strength of TLCP fiber gives the protrusions excellent abrasion resistance, while the recesses 5 are used to temporarily retain moisture and increase the evaporation area. This design causes the stress of the contact layer 1 to concentrate on the protrusions 4 when subjected to external friction, which greatly improves the overall abrasion resistance life of the fabric.

[0023] like Figure 3 As shown, the intermediate layer 2 has several vertically arranged ventilation channels 6. The intermediate layer 2 is made of aramid fiber and is woven using the warp knitting interval technology of the aforementioned double-needle bed warp knitting machine. Its loop-forming mechanism connects the two sides to form a three-dimensional spaced yarn structure, thereby constructing the ventilation channels 6. All ventilation channels 6 have diamond-shaped openings, with the opening size on the side facing the comfort layer 3 being smaller than the opening size on the side facing the contact layer 1. This gradient diamond-shaped channel structure generates a capillary moisture-wicking effect, guiding moisture from the comfort layer 3 with its smaller opening to the contact layer 1 with its larger opening and accelerating evaporation. This achieves excellent one-way moisture wicking and a ventilation function similar to the "chimney effect," ensuring high breathability.

[0024] like Figure 1As shown, the comfort layer 3 is made of a blend of 50% polypropylene fiber and 50% nylon fiber. The comfort layer 3 contains an antibacterial substance 7, which is silver ions. During production, silver ion antibacterial masterbatch is blended with polypropylene and nylon polymers during the spinning stage to create an antibacterial composite fiber with embedded silver ions. This fiber is then woven into the layer using a warp knitting machine. The silver ions are encapsulated within the fiber, giving the antibacterial function excellent wash resistance and durability, effectively inhibiting bacterial growth and preventing odors. Simultaneously, the comfort layer 3 is soft to the touch, wicks away moisture quickly, and provides high comfort when worn close to the skin.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
