Description

Technical Field

[0001] This utility model relates to a flame-retardant composite fabric for outdoor tents, belonging to the technical field of outdoor composite fabrics. Background Technology

[0002] With societal development, people are experiencing increasing life pressures, especially those living in concrete jungles of cities. People yearn to relax and go camping outdoors. Outdoor camping tents are essential equipment. As crucial equipment for outdoor activities, outdoor tents need to withstand the challenges of complex environments, requiring functions such as sunshade, windproofing, waterproofing, rainproofing, and heat insulation, and even flame retardancy. Existing tent fabrics generally suffer from the following problems:

[0003] 1. Insufficient flame retardant properties: Traditional fabrics are mostly treated with flame retardants in the finishing process, which results in poor washability and easy failure at high temperatures;

[0004] 2. The contradiction between waterproofing and breathability: single-layer waterproof membranes have poor breathability, while multi-layer composite structures can easily lead to heavy fabrics and reduced comfort;

[0005] 3. Insufficient structural strength: Long-term outdoor use makes it prone to wear and tear, affecting its service life.

[0006] Therefore, there is a need for a flame-retardant composite fabric that integrates multiple functions through structural optimization and can be used in outdoor tents. Utility Model Content

[0007] The purpose of this invention is to provide a flame-retardant composite fabric for outdoor tents, which has waterproof, flame-retardant, and tear-resistant properties, and is also breathable.

[0008] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0009] The present invention relates to a flame-retardant composite fabric for outdoor tents, comprising a fabric surface layer, a flame-retardant fabric layer, and a fabric inner layer bonded together by a breathable adhesive.

[0010] The outer layer of the fabric is a plain weave fabric woven from flame-retardant polyester filaments; the inner layer of the fabric is a planar triaxial fabric woven from bio-based polyamide 56 filaments at a 60° angle.

[0011] The surface of the fabric layer away from the flame-retardant fabric layer is bonded with a flame-retardant, waterproof, and breathable membrane by a breathable adhesive.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the flame-retardant waterproof and breathable membrane is a PTFE waterproof and breathable membrane.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the flame-retardant fabric layer includes a flame-retardant nonwoven fabric layer and a bromine-antimony flame-retardant finishing coating applied to both sides of the flame-retardant nonwoven fabric.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the flame-retardant nonwoven fabric layer is flame-retardant viscose hydroentangled nonwoven fabric or flame-retardant aramid 1313 needle-punched nonwoven fabric.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: a SiO2 aerogel hybrid aramid nonwoven fabric is provided between the flame-retardant fabric layer and the inner fabric layer.

[0016] The beneficial effects of this utility model are as follows: The flame-retardant fabric for outdoor tents disclosed in this utility model uses a planar three-dimensional fabric formed by interlacing bio-based polyamide 56 filaments, which gives the fabric excellent tear resistance in all directions. The flame-retardant, waterproof, and breathable membrane provides both flame retardancy and waterproof breathability. The flame-retardant polyester filaments also provide flame retardancy.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] Combination Figure 1 This embodiment will be described in detail below. The flame-retardant composite fabric for outdoor tents involved in this embodiment includes a fabric surface layer 1, a flame-retardant fabric layer 2, and a fabric inner layer 3, all bonded together by a breathable adhesive. Specifically, the breathable adhesive is a flame-retardant hot melt adhesive web, which provides good adhesion while also being breathable.

[0023] The outer layer 1 of the fabric is a plain weave fabric woven from flame-retardant polyester filaments; the inner layer 3 of the fabric is a planar three-way fabric woven from bio-based polyamide 56 filaments at a 60° angle; and the surface of the outer layer 1 away from the flame-retardant fabric layer 2 is laminated with a flame-retardant, waterproof, and breathable membrane 4 by a breathable adhesive.

[0024] Furthermore, the flame-retardant waterproof and breathable membrane 4 is a PTFE waterproof and breathable membrane. In addition to being waterproof and breathable, the PTFE waterproof and breathable membrane also has good flame-retardant, UV-resistant, and corrosion-resistant properties.
