The working principle of polyester fireproof oxford fabric is mainly through the use of special chemical properties of special product materials. When it encounters open flames or other conditions, it will show flame retardant properties.
The working principle of polyester fireproof oxford fabric mainly lies in:
[Polyester fireproof oxford cloth] The operating principle of the fabric is mainly through the use of special product materials with special chemical properties. When exposed to open flames or other conditions, it will show flame retardant properties. Fireproof Oxford cloth is a kind of high-temperature inorganic fiber material with stable chemical properties, high temperature resistance, ablation resistance and other characteristics. Now fireproof Oxford cloth fabrics are not only used in special industries, but also used in aviation, chemicals, building materials, Fire and other categories. The meaning of waterproof Oxford cloth is that a post-treatment is added to the grey cloth to make the Oxford cloth waterproof. The main functions of waterproof Oxford cloth are: waterproof, breathable, breathable, insulating, windproof and warm.
According to the different coating materials of [Polyester fireproof Oxford cloth], there are three types: PVC coating, PU coating and semi-PU coating. Depending on the coating process, there are mercerized leather, matte, anti-dermis, wrinkle leather, etc. There are also classifications based on functions and characteristics. Such as: coloring glue, PVC coating, silver coating, calendering, flame retardant, PA moisture permeability, PU moisture permeability and so on. Special coating: rubber-like coating, paper-like processing, waterproof and breathable, pearlescent series, oil wax-like coating, PU gold glue silver glue, high water pressure series (up to 1000---10000), UV- CUT anti-UV processing and so on.
Polyester fireproof oxford fabric is mainly made of fireproof and non-combustible fiber, processed by special process. Main features: non-combustible, high temperature resistance (550-1100 degrees), tight structure, non-irritating, soft and resistant, and convenient to bandage objects and equipment with uneven appearance. Fireproof cloth has a good maintenance of objects away from hot spots and spark areas, and polyester fireproof Oxford cloth can completely prevent or block incineration. Yuqi fireproof Oxford cloth can be used in any environment such as humidity, steam, smoke, chemical gas, etc., playing a good role in fire protection and maintenance. It has flame retardant effects such as extinguishing fire source and blocking sparks. Therefore, it has become a better helper for industrial day fire protection and maintenance, and has a more extensive use! Become a must for interior decoration materials and industrial high temperature fire protection!
These coatings on polyester tent fabrics not only have the function of releasing water, but also have the ability to breathe. They are called breathable fabrics. The principle of air permeability is that the coating is a porous film, and the diameter of a single hole is smaller than gas water molecules but larger than liquid water molecules. In this way, outside rain water cannot pass through the coating, and water vapor emitted by the human body can penetrate to the outside world. It should be noted that the air permeability of the breathable fabric is bidirectional, so when the external humidity is relatively high, the moisture will certainly penetrate to the inside of the fabric.
[Polyester fireproof Oxford cloth] Inspection method: all coated or laminated fabrics are fixed on the support frame with rubber rings, and the coated or laminated surface faces outward. The equipment of the sample support system should be able to float in a tank with a water temperature of 23°C. After testing the quality of the test cup (including the sample, desiccant and film) with the film facing upwards, quickly turn the test cup upside down and place it in the sample holder. This installation method is placed in a constant temperature 30℃±2℃ equipment. After 15 minutes, take the test cup out of the thermostat, turn the polyester fireproof Oxford cloth upside down and measure its weight. The above are the more useful methods for testing waterproof Oxford fabrics at home and abroad. Most of the waterproof Oxford fabrics that have passed these tests can achieve waterproof and moisture-proof effects.
