Tent style and material analysis

Design is certainly a factor in the quality of tents, but the choice of materials is crucial. Materials can be divided into fabrics, linings, bottom materials, struts, etc. Generally speaking, fabrics with the same label have different densities, so the tensile strength and waterproof pressure are also different. Compared with different fabrics, nylon silk is thin and light. , suitable for mountaineering and hiking campers, Oxford cloth is thick, but heavier, suitable for making tents for driving camping or small groups. From the perspective of waterproof coating, although PVC is waterproof, it will be hard and brittle in winter, and it is easy to creases or break. PU coating can not only overcome the defects of PVC, but also waterproof. PU with multiple coatings, the waterproof pressure can reach more than 2000MM. The lining of the tent (inner tent material) is usually made of cotton nylon silk with good air permeability. From the point of view of use, the performance of nylon silk is better than that of cotton. Camping in the wild, tents can easily absorb moisture, cotton cloth is not easy to cool and mildew, and nylon silk is easy to dry and not easy to mold. The main function of the tent bottom is waterproof, moisture-proof and dust-proof. The choice of bottom material also determines the grade of the tent. Low-grade tents usually use PE as the bottom material, and PVC is also used. What is required is low cost, double-sided coated PE, although it has waterproof and moisture-proof functions, but it is easy to wear and leak. . Winter is the nemesis of PVC backing, and PU-coated Oxford cloth as backing material greatly exceeds PE in terms of firmness, cold resistance, and water resistance. The pole of the tent is the skeleton of the tent. The quality of the skeleton material not only affects the life of the tent, but also affects the stability of the tent. When choosing and using a camping tent, you should first understand its subdivisions and styles. There are currently many types of tents on the market. As far as their classification is concerned, ALICE friends who play outdoors like to divide them into two categories: One is: alpine tents, mainly for coping with It is designed for relatively harsh conditions, and its performance indicators focus on wind resistance, rain resistance, and high strength. The selection of materials is more elegant, and the production process is more complicated. climate environment. The other type is what we usually call, tourism type, designed for general outings and camping. The selection of materials pays more attention to economy, and the production process is relatively simple. It is a low-grade tent and can be used as a tent in a general environment camping activities. The structure and specifications of the tent are different due to the different requirements of travelers, and the tent design is divided into different structural forms, which can be divided into single-room structure and hall-style structure: The space of the single-room structure is only for sleeping. Design, focusing on reducing size and weight. The tent with the canopy structure is to set up an outer hall with a door in addition to the sleeping space. In addition to its superiority in windproof and rainproof, it also provides a space for the existence of equipment. In order to adapt to different temperature environments, tents are divided into different structures such as single-layer, double-layer, and three-layer: The advantages of single-layer are light, economical, small in size, and relatively simple in production process. The difference between the double layer and the single layer is that a layer of inner tent with better air permeability is added in the design, which mainly solves the contradiction of water condensation on the inner wall of the single layer tent. Because in the cooler season, the heat released by the human body will condense water droplets on the inner wall of the tent under the action of the cold air outside the tent, and the accumulated water will flow down the inner wall of the tent and wet the sleeping bag. The tent is not directly connected to the bottom of the inner tent, the heat emitted by the human body will pass through the inner tent, and the water droplets condensed on the outer tent can flow directly to the ground. In this sense, single-layer tents are mainly suitable for warmer areas or seasons. Double tents are suitable for cool seasons or cold regions. The design of the three-layer tent is to add another layer of cotton tent to the inner tent, which further enhances the thermal insulation effect. This tent is used in an environment of minus 10 degrees, and the temperature in the tent can rise to about zero degrees. The early tent poles were often made of reinforced materials, which not only increased the weight of the tent, but also had poor resilience. The improved tent frame is made of fiberglass struts, which is lighter in weight, improved in resilience, and low in cost. Therefore, current tent manufacturers mostly use this material as struts, but the strength and sturdiness of the fiberglass struts Neither is ideal. If the strength is increased by thickening the fiberglass struts, it also increases the weight. The ideal strut is aluminum alloy material. The strut connected with high-strength alloy tubes is not only high in strength, but also light in weight and good in resilience. In particular, the EASTON struts made of aerospace aluminum materials have reached the state of all indicators, so they are mostly used for secondary tents. The main performance indicators of the quality of tents are generally based on wind resistance, rain resistance and good stability. Alpine tents also require light weight and small size. A high-performance alpine tent usually uses a tear-proof structural fabric woven from nylon silk, plus a waterproof coating with a waterproof degree of more than 2000mm, and the seam is glued in the production process, which can ensure that you are in a heavy rain environment. ,Not disturbed by wind and rain. If you use high-strength EASTON struts as the skeleton, even if the wind is above level 8, you will be safe. However, such tents are expensive, and the general market price is more than 2,000 yuan. If you use GORE's ACTIVEN fabric as the outer tent, you can In terms of structure, the inner tent can be omitted, and the weight and volume can be reduced, and its water resistance, breathability, and anti-condensation performance are good, but the price will be high.
