The tent fabric catagories and wtare-proof performance.

The quality of tent fabrics depends on the quality first, not just the parameters. It is also necessary to know the quality of the embryo fabric (untreated raw materials), what quality yarn is used, the density (that is, the T value of the fabric), and the thickness. (that is, the D value of the fabric), how to deal with the later process, etc.

The fabric of the tent is mainly divided into three parts: outer tent fabric, inner tent fabric, and bottom tent fabric.

  1. The outer account mainly uses five materials: nylon, canvas, TC cloth, sephora, Gore-tex
  2. The inner tent material is usually made of cotton nylon silk with good air permeability.
  3. The main function of the material at the bottom of the account is waterproof, moisture-proof and dust-proof

Some of the fabrics mentioned here are useful, but they are relatively few. Most of the tent fabrics on the market are nylon, polyester, Oxford cloth, polyurethane and the like.
Regarding hydrostatic pressure, that is, the precipitation pressure that the fabric is subjected to. Most fabrics are waterproofed by coating.

Most of the ordinary fabrics are waterproofed by PU transparent coating, so the function will be relatively simple, and some fabrics will use silicon coating, silver coating, black glue coating, colored coating to achieve waterproof and sunscreen performance, and some It is not that the thicker the coating, the more suitable for tents, such as lightweight fabrics. Too thick coating will affect the tearing performance of the fabric, so the hydrostatic pressure value is not as high as possible.

Commonly seen fabric specifications: 210T, 15D, Oxford cloth, PET (polyester fiber), silicone rubber fiberglass cloth, PU (polyurethane), DCF, etc. What do they mean?

One, T, D

T and D are units for evaluating different properties of materials, and only the same units can be compared. The main differences are:

D in the fabric: Denier = g/L*9000 where g is the weight of the thread (grams), L is the length of the thread (m), in fact, you don’t need to remember any formula, it actually expresses The weight of the silk thread per unit length. For example, the bottom fabric of many backpacks is made of DuPont’s 1000D nylon, which has a very high density and is very wear-resistant. Then, in other parts of the backpack that are not easy to wear, the material can be 600D or 600D. 420D nylon,

Their relative density is smaller, and the larger the number before D, the heavier the cloth of the same area.

Usually tents use 150D or 70D nylon, taking into account cost/weight/wear resistance, but on some high-end tents, fabrics above 40D are used to reduce weight to the greatest extent, at the cost of a substantial increase in cost and relative wear resistance. reduce.

The T in the fabric generally refers to polyester taffeta, which is a nylon, imitation silk fabric, generally used as the outer and inner tents of tents. It is light and strong, such as 190T, and the number in front represents the warp and weft roots within 1 inch. The sum of numbers (density) is actually a unit of density. You can also simply think that the larger the number before T, the heavier the cloth of the same area.

  1. Different weights, T is the unit of quantity of warp and weft threads within 1 square inch, that is, the diameter of fabric fibers; the larger the number in front of T, the greater the weight, and there is no D waterproof; light, and high tear resistance.
  2. D is the weight unit of the thread, that is, the thickness of the thread diameter, which can also be understood as the fabric density. The larger the number in front of D, the more wear-resistant and heavier it is; the finer the number, the better the breathability.
  3. The price is different, the larger the number in front of T, of course, the price is relatively cheaper;
  4. The smaller the number in front of D, the thinner and more transparent the tent, raincoat, etc., of course, the price is relatively expensive.
  5. Oxford cloth

Oxford cloth (oxford) is a cotton-like fabric, soft, smooth and wear-resistant, usually used as the bottom of the account, so the bottom of the account is usually marked as XXXDnylonoxford. Strong waterproof, good heat insulation effect, not hot from the sun, but hard and bulky, easy to fade, but wear-resistant, generally used for tent bottom fabrics. PE refers to polyethylene or ethylene, which is low in cost, waterproof, and does not need to be glued. Therefore, it is used as the bottom of many low-cost tents. The appearance is similar to the sackcloth of small squares. Very durable.

  1. PET fiber (polyester fiber)

The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. It is durable, wrinkle-resistant, non-iron, and non-sticky.

The disadvantage is that the water absorption is not strong, and it is easy to absorb dust.

  1. Silicone rubber fiberglass cloth

It is a high-performance and multi-purpose composite material, which is made of high-temperature resistant and high-strength glass fiber cloth as the base material and made of silicone rubber through a special process.

High temperature resistance, aging resistance, high waterproof, light enough, high tear resistance. But the fabric feels rough and is rarely used on tents.

  1. PU (polyurethane)

PU refers to polyurethane (polyurethane) or spandex, which is usually used as a waterproof glue. Neither polyester taffeta nor Oxford cloth itself is waterproof and must be glued. The number indicates the water pressure resistance value. For example, PU2000mm means that there will be no leakage under the water pressure lower than 2000mm. The manufacturer clamps the tent cloth on a circular kit during the test, and then pressurizes the water with an electric method. When the third drop of water seeps out of the tent , the water pressure value at this time is the waterproof value. Polyurethane (PU) coated Oxford cloth as the base material greatly exceeds PE and PVC in terms of firmness, cold resistance and waterproofness. PU coating can not only overcome the defects of PVC, but also waterproof. The waterproof pressure of PU with multiple coatings can reach more than 2000MM, and PU is often mixed with other fabrics.

  1. DCF

A top-level cloth material, the most expensive cloth, but light, waterproof, tear-resistant, etc., but really quite expensive.

For the external account, considering its fragility in harsh environment, it should be noted whether it adopts a ripstop structure. bigger.

Hydrostatic pressure: 2000mm-3000mm can prevent heavy rain or rainstorm.

In my opinion, different fabrics will have different performances in the natural environment, and they need to be used in different product models, so as to better reflect the different performances reflected by the different needs of tents.

So what is the concept of 2000mm water pressure? Usually the waterproof capacity of the umbrella is PU1000mm. If the glue level of the tent outside the tent is lower than this value, it can basically be considered that leakage will definitely occur under heavy rain.

If you want to ensure the reliability of the tent’s weatherproofing, considering the wear of the glue, the glue on the outer tent should not be less than 1200mm, and because the bottom of the tent has to bear the weight of people lying on it, the glue pressure requirements are higher, usually at least Should be above 2000mm.

In addition, new tent tents are usually treated with water repellency, and their waterproof ability will gradually disappear with the wear and tear of the water repellent agent. Some manufacturers will reduce the PU value to reduce costs. This is why some The reason why the tent has good rain protection when it is bought, but it loses its rain resistance after a few uses.
