Features And Uses Of Common Clothing Fabrics

Several kinds of chemical fiber materials in outdoor products

1. polyester: polyester fiber, also known as POLYESTER.

It is characterized by good air permeability and moisture retention, strong acid resistance, alkali resistance and UV resistance. The disadvantage is that there is electrostatic problem, that is, it is easy to stain dirt.

Often used for heating materials and quick drying.

。

The more famous materials are DUPONT's COOLMAX, MALDEN MILLS's POLARTEC.

2. spandex: stretch nylon, also known as SPANDEX.

The advantages are high elasticity and high flexibility and good recovery. In general, 2% can improve the sense of movement, drape and preservation of the fabric. The weak point is resistance to alkalinity. When exposed to chlorine or ultraviolet radiation, it will become yellow and embrittlement.

3. nylon: nylon, also known as Nylon, polyamide fiber.

The advantages are high strength, high wear resistance, high chemical resistance, good resistance to deformation, aging resistance, and the disadvantage is that the handle is hard.

The most common outdoor materials are widely used in backpacks, sleeping bags, clothing and tent materials.

The more famous ones are PERTEX, CORDURA.

Fiber materials related indicators:

D: Daniel, a unit for measuring the density of textile fibers, showing the weight of each 9000 meter fiber (that is, the lower Daniel is, the finer the fiber).

Formula D=G/L*9000.

That is fiber weight / fiber length *9000.

It is commonly used in fabric strength index of knapsack fabric.

Commonly used 450D, 500D.

Materials above 500D are generally used for easy wearing parts, such as the bottom of the backpack.

T: tex, referred to as "special", a unit for measuring the density of textile fibers.

It refers to the weight grams of 1000 meter long fibers or yarns at a constant moisture regain.

Formula T=G/L*1000, namely fiber weight / fiber length *1000.

Common in down products

The density index of tent fabric is better than that of 240T.

Introduction of common fabrics

The 300 series is warmer and does not need to go cold.

There are also 200BiPolar and 300BiPolar series. These are double-layer sweaters, which are thicker.

BiPolar has stronger thermal insulation and is suitable for wearing in alpine region.

It is worth noting that most people buy the best 200 series, and if they are cold, they can wear a down vest.

More than 300 of them are relatively heavy and some are wrapped up in barren areas. They are too hot to wear and take off cold. They are not very suitable for daily wear.

PROO-TEC LM is another new material developed on the basis of PROO-TEC platform. On the basis of keeping water repellency and permeability, it has better softness and comfort compared with PROO-TEC, and also greatly reduces the self weight of equipment. It is the material for producing high-end down coat, down sleeping bag and high mountain light proof windbreaker.

In harsh environment, the down products made of PROO-TEC LM have better thermal insulation and good heat resistance as well as wind and snow.

It should be noted that PROO-TEC LM products are generally used only in cold climates, and are generally mainly ice snow and melted water. Therefore, it is difficult to cope with heavy rain without pressing glue on the seams.

SOFT-B is specially developed for down products.

The outer material is made of Nylon or Polyester with a density of more than 300T. It is characterized by high strength, light weight, soft resistance, anti penetration, and breathability.

SOFT-B is different from the traditional feather products to prevent the down leakage through the anti cashmere coating. Instead, it is made up of a dense and breathable layer with CIRE technology on the surface of the fabric. With its high density, it can effectively prevent the anti drills. The most important thing is to maintain high permeability.
