Currently Xinke flame retardant fabric performance testing more mature testing methods include : horizontal combustion method , the vertical combustion method , 45o combustion, oxygen index method , different test methods reflect the combustion properties of the fabric from a different side . Assessment of flame retardant textiles generally use the following indicators: continued burning time , smoldering time , damage length , flame spread time , the flame spread rate, flame spread distance, burning rate , the minimum ignition time , limiting oxygen index , minus extinction coefficient , radiation flux and so on.
Flame retardant fabric testing standards following problems :
First, many indicators , duplicate , shall be unified simplification , such as " flame spread time , the flame spread rate, flame spread from the burning speed" these indicators are actually expressing a meaning, namely the burning speed.
Second is the performance of textile flame burning mostly textiles evaluate the ease and speed of the combustion degree .
Third, the existing standard system mainly for fabric flame test methods , rather than loose fibers. Because the combustion properties of textile materials, not only their own properties and materials , but also on the structure and terms of aggregates , such as fiber blends relevant circumstances . However, the fiber is flame retardant blank test methods and standards restricting the flame retardant fiber product development and marketing, if each test will be woven into cloth fiber spinning , and then detect the combustion performance of the sample, it would result in the experimental period long , higher other costs adversely affected.

What are the general characteristics of flame retardant fabrics
Xinke fire retardant fabric is also divided into a few lines Standard: British standard ( the highest level BS5852) current domestic energy standards for minorities , is that you can do so through the fire , but not stability testing because of the large fire intensity while corrosion is also a large impact on the fabric also great. American Standard is once again the fire ( for middle level 117 ) , widely used in the country , generally a few seconds to leave also can extinguish the flame . There is a fire after domestic manufacturers do a good finishing is good , is to detect internal testing standards in general is no big factory certification of any particular country . But knowledgeable can detect under their own hand , a lighter can be lit after leaving the flame goes out to see his speed, if the speed can also be extinguished fire is ideal .
General characteristics of flame retardant fabrics , flame retardant basic classification , also known as Xinke fire retardant fabric .
For example, most would choose curtains immersion fire , because the requirements good drape curtains , seat fabrics and thin will adopt immersion fire , to prevent overflow slurry coating on the back of the front , these are actual examples we can experience .
Again that is generally taken to spray fire screens , there are many minor fire can take this approach general characteristics of the original fabric is not changed substantially.
Retardant fabric, fireproof fabric is widely used in high-end engineering software packages , such as crowded train car facilities , as well as hotels , cinemas , and so we can think of the public will be used, will need these protective measures, as well as private sofa seat Seat covers European countries are paying attention to this problem, it is widely used in fireproof fabric of our lives.
Fireproof fabric can be divided into: a coating of fire , soaked fire , and spray fire , these methods also depends on what fabric is applied . Such as sand release coating they generally take advantage of the fire , the coating is to prevent fire affected fire retardant cloth produce a color change , velvety changes, etc. , is once again make the fabric more stiff fireproof coating thicker and more solid .

The test of flame retardant protective clothing
Xinke flame retardant coveralls is in direct contact with the flame and
hot objects, can slow the spread of flame, carbonized form isolation
layer in order to protect human safety and health of a protective
clothing. Countries around the world each year hundreds of thousands of
people get burnt by clothing, also found that often comes from the most
serious burns clothes rather than burning flame itself, degree of burn
skin burn under clothing is often more serious than directly exposed
skin. As to ensure life safety and health of a human body protection
articles, Xinke flame retardant coveralls protective clothing is widely used in
metallurgy, petrochemical industry, welding and other industries, with
the improvement of people security awareness and protection knowledge
and the development of the domestic protective clothing production,
expanding the application range of the flame retardant protective
clothing.
Flame retardant protective clothing thermal
protective performance is generally produced clothing material flame
retardant performance to determine its quality. In addition to the flame
retardant performance, thermal insulating protective clothing stays,
integrity, and resistance to liquid permeability is to determine an
important index of flame retardant protective clothing thermal
protection performance. Some technology in developed countries such as
America, Europe, Australia and other countries and regions have
developed a complete evaluation of flame retardant performance testing
methods.

The function of flame retardant fabric
flame retardant coveralls, also known as flame retardant fabric. When it comes to flame retardant cloth, fire-retardant is away from the fire that is known to all, not secondary, do not continue to burn out of the cloth, so what's the function of flame retardant cloth?
A. flame retardant is not equal to non-combustible, is to extend the time of fire, such as reach for prolonging 20-30 seconds after the ignition is on fire, to try and fire off clothes time, reduce the degree of burn.
B. don't delay burning, under the environment of high temperature flame retardant design time or temperature, the performance is also invalid.
C. don't continue burning, need to see the fire condition and the environment, if the fire sufficient oxygen supply, keypad is too high, the possibility of continue burning still exist.
D. all kinds of fabric can make use of flame retardant treatment, and flame retardant function also is closely associated with the physical and chemical properties of materials, the fabrics of different material while using the same flame retardants, its flame retardant effect also each are not identical, to note.
E. away from the fire is out, need to see in the midst of the fire temperature and air (oxygen), and the length of time the environment of high temperature. Flame retardant effect exceeds its limits or can play a role of time, the flame retardant effect disappeared, with ordinary fabric.
