Description

Technical Field

[0001] This utility model relates to a double-sided composite bag fabric and a bag, belonging to the technical field of bags and bag fabrics. Background Technology

[0002] Bags and luggage are frequently used items in daily life and travel, serving to store various belongings while protecting them. These include shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of rolling suitcases. However, the fabrics used in existing bags and luggage typically have the same properties on both sides. This results in a lack of difference in appearance between the inside and outside of the bag. Therefore, the problem to be solved is how to develop a double-sided composite bag and luggage fabric that allows for different textures and appearances on both sides. Utility Model Content

[0003] The purpose of this invention is to provide a double-sided composite bag fabric and bag, wherein the properties of the two surfaces of the fabric are different.

[0006] The napped fabric layer has a hot stamping layer on the napped side, and the side of the hot stamping layer away from the napped fabric layer is coated with a flame-retardant water-based polyurethane coating; the flame-retardant water-based polyurethane coating has micropores with a diameter of 0.1-10 micrometers.

[0007] The tear-resistant fabric layer is laminated with a microfiber acrylic fabric on the side away from the napped fabric layer; the microfiber acrylic fabric layer is woven from Dralon microfiber acrylic fiber yarns.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the tear-resistant fabric layer is a planar triaxial fabric woven from first yarns; the first yarns include parallel ultra-high molecular weight polyethylene long yarns and hot-melt filaments.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the hot melt filament is nylon hot melt filament, polyester hot melt filament or TPU hot melt filament.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: a heat-insulating fabric layer is provided between the tear-resistant fabric layer and the ultra-fine denier acrylic fabric layer; the heat-insulating fabric layer is made of interwoven aerogel fiber yarns.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the fiber used in the aerogel fiber yarn is nano-aramid aerogel fiber.

[0012] This utility model also relates to a bag, including the above-mentioned double-sided composite bag fabric.

[0013] The beneficial effects of this utility model are: the double-sided composite bag fabric and bag involved in this utility model use a napped fabric layer with a hot stamping layer and a fleece layer on one side, and an ultra-fine denier acrylic fabric layer on the other side, so that the performance of the two sides of the fabric is different.

[0014] Figure 1 This is a structural schematic diagram of the double-sided composite bag fabric involved in Example 1;

[0015] Figure 2 This is a structural schematic diagram of the double-sided composite bag fabric involved in Example 2.

[0016] The markings in the diagram are explained as follows: 1-Tear-resistant fabric layer; 2-Pile fabric layer; 3-Hot stamping layer; 4-Flame-retardant water-based polyurethane coating; 5-Micro denier acrylic fabric layer; 6-Heat-insulating fabric layer. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1 This embodiment will be described in detail below. The double-sided composite bag fabric involved in this embodiment includes a tear-resistant fabric layer 1; a napped fabric layer 2 is laminated to one side of the tear-resistant fabric layer 1, the napped fabric layer 2 has pile formed by napping on one side, a hot stamping layer 3 is provided on the napped side of the napped fabric layer 2, and a flame-retardant water-based polyurethane coating 4 is coated on the side of the hot stamping layer 3 away from the napped fabric layer 2; the flame-retardant water-based polyurethane coating 4 has micropores with a diameter of 0.1-10 micrometers; an ultra-fine denier acrylic fabric layer 5 is laminated to the side of the tear-resistant fabric layer 1 away from the napped fabric layer 2; the ultra-fine denier acrylic fabric layer is woven from Dralon ultra-fine denier acrylic fiber yarns.

[0020] The napped fabric layer 2 is woven from warp and weft yarns in a weft-faced satin weave. The warp yarns are 75D / 72F polyester filaments, and the weft yarns are nylon-polyester blended yarns. These blended yarns include 35-60D / 48-96F flame-retardant nylon filaments and 75D / 144-288F flame-retardant polyester filaments. Network dots are evenly distributed along the length direction to fix and connect the nylon and polyester filaments. In this embodiment, the nylon-polyester blended yarns use nylon 6 with a fineness of 60D / 96F; the polyester filaments used are 75D / 288F. The polyester monofilaments used have a high degree of fineness, resulting in a finer nap after napping. In this embodiment, the napped fabric layer 2 is napped on the weft side only.

[0021] Furthermore, the tear-resistant fabric layer 1 is a planar triaxial fabric woven from first yarns; the first yarns include parallel ultra-high molecular weight polyethylene (UHMWPE) long yarns and thermoplastic filaments. The planar triaxial fabric is woven from three sets of first warp yarns at a 60° angle. This planar triaxial fabric exhibits isotropic mechanical properties; regardless of the direction of stress, its deformation exhibits a fairly uniform and equal strain, overcoming the significant difference in shear and tensile strength present in biaxial fabrics at a 45° angle. The UHMWPE filaments used in the planar triaxial fabric have high strength, and the thermoplastic filaments arranged parallel to them melt after heat treatment, allowing adjacent UHMWPE filaments to bond together, thereby reducing slippage of the UHMWPE filaments.

[0022] The uniform micropores on the flame-retardant waterborne polyurethane coating 4 have a diameter ranging from 0.1 to 10 micrometers, achieving a breathable and waterproof effect. Furthermore, the excellent abrasion resistance of the polyurethane coating improves the abrasion resistance of the faux suede hot stamping fabric and provides excellent protection for the hot stamping layer 3, preventing damage during use.

[0023] Furthermore, the flame-retardant waterborne polyurethane coating 4 uses nitrogen-based flame-retardant waterborne polyurethane.

[0024] Furthermore, the hot-melt filament is nylon hot-melt filament, polyester hot-melt filament, or TPU hot-melt filament. In this embodiment, polyester hot-melt filament is selected. The polyester hot-melt filament includes a core layer and a sheath layer. The sheath layer is low-melting-point polyester, while the core layer is conventional polyester. The melting point of low-melting-point polyester is lower than that of conventional polyester material.

[0025] Example 2

[0026] Combination Figure 2This embodiment will be described in detail below. The difference between this embodiment and Embodiment 1 is that a heat-insulating fabric layer 6 is provided between the tear-resistant fabric layer 1 and the ultra-fine denier acrylic fabric layer 5; the heat-insulating fabric layer 3 is woven from aerogel fiber yarns. The fibers used in the aerogel fiber yarns are nano-aramid aerogel fibers.

[0027] Example 3

[0028] The bag involved in this embodiment specifically uses the double-sided composite bag fabric involved in Embodiment 1 or Embodiment 2.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
