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

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.

Flame retardant fabric color difference
1. The dyeing products from different shades of colour and lustre, color has a difference.
Color: (1) the same batch of flame retardant fabric with batch of products. A color number between product box and the box, and parts, between package and package, there is flame retardant fabric color difference between horse and horse.
(2) and the flame retardant fabric color difference: the horse and horse before and after the product of the fact in flame retardant fabric color or have flame retardant fabric color or both the flame retardant fabric color difference. Flame retardant fabric color is one of the common fault and multiple fault dyeing factory, seriously affect the dyeing quality of the finished product.
2. The reason
Fiber of of all kinds of fabric, dyed with different kinds of dyes and process equipment, and have different requirements and characteristics of the dyeing processing, and the causes of fault and the performance is different. Flame retardant fabric color difference on the appearance of performance varied, but investigate its reason, mainly has the following kinds.
(1) : the uneven distribution of dye on the fabric with the first before dye fixation, if uneven distribution in each part of the fabric, after fixation will generate flame retardant fabric color difference. The main cause of this phenomenon is:
1.. Fabric: due to the different fiber performance or pretreatment, boiling, bleaching, silk back not divide evenly, make dye permeability caused by uneven tire before the dye absorption degree of difference.
2.. Suction fluid factors: because of mechanical structure or improper operation, make each part of the fabric with liquid rate, resulting in flame retardant fabric color difference. Roll pressure not divide evenly, add dyestuff is not well and can make fabric absorb dye unevenness.
3.. Preliminary drying factors: a preliminary drying after the pad dyeing liquid, due to the drying rate and degree of inconsistency, cause varying degrees of dye migration, the dyes on the fabric distribution is uneven.
(2) the degree of the dye fixation on the fabric is different: although the dye on the fabric with the first distribution is uniform, but in the process of fixation. Such as the improper control of conditions (such as temperature, time, concentration of dyestuff, etc.), make certain parts of the dyes on the fabric has not been fully solid color, has been removed. In the post-processing soaping to produce flame retardant fabric color difference. Disperse dye, for example, thermosol temperature on both sides or inconsistent, VAT dye partial oxidation reduction or inadequate, such as reactive dyes adverse steaming conditions can cause the fabric before and after around or have a flame retardant fabric color difference.
(3) dye color change: the difference is not caused by uneven distribution of dyes on the fabric. But for some reason cause part of dye on the fabric color change, generally has the following several reasons:
1.. Before dyeing factors: whiteness of semi-product uneven or pH have bigger difference, often cause color difference after dyeing.
2.. Dyeing factors: such as disperse dye thermosol temperature is too high, make some dye color shade walls of dark; The excessive reduction of VAT dye, also can make color difference.
3.. After dyeing factors: after finishing process. High temperature, such as resin finishing, stentering and different PH value on fabric, colored light have different degree of change will cause dye.
Color: (1) the same batch of flame retardant fabric with batch of products. A color number between product box and the box, and parts, between package and package, there is flame retardant fabric color difference between horse and horse.
(2) and the flame retardant fabric color difference: the horse and horse before and after the product of the fact in flame retardant fabric color or have flame retardant fabric color or both the flame retardant fabric color difference.

Uv protection fabric
In recent years, due to containing halogen compounds such as freon a large amount of emissions, stranded over the earth, is broken down by ultraviolet (uv) formation of active chlorine and ozone chain chemical reactions occur, ruined the ozone in the air is hollow, the ultraviolet radiation to the ground, ultraviolet rays will cause harm to people's skin. According to scientists, predicts that by 2050 the stratosphere ozone would be reduced about 20%, then uv will bring greater harm to human health. As a result, people have developed which has the function of u.v fabric and textiles.
The principle of textile ultraviolet resistance
uv protection fabric, the mechanism has two kinds: absorption and reflection. Ultraviolet screening agent have accordingly absorption agent and reflection agent (or scattering jing) two kinds. Absorption agent and reflection agent can be used alone, also can be a mixture of both.
Uv reflection agent mainly using the reflection and scattering effect of inorganic particles, can have the effect of uv light through. Uv absorber mainly use organic material to absorb ultraviolet light, and energy transformation, in the form of heat or harmless low radiation will release or consume energy. Uv protection textiles with appropriate method processing, whatever the fiber material, can achieve good uv protection effect, and the thickness of the fabric, color and so on factors affect the performance of uv is no longer important.
