Flame-retardant fabrics and flame-retardant fabrics are not not on fire, but ordinary fabrics have the performance of preventing the flame from spreading continuously after the flame-retardant finishing, and cannot continue to burn when the flame is removed. It is the most indispensable product in protective clothing at this stage. Because of the continuous improvement of people's safety awareness, the awareness and demand for protective products are also increasing, but there are still many customers who do not have enough understanding of flame retardant fabrics, so there are many questions when buying and choosing. Here, for everyone Some common problems of flame retardant fabrics are organized for your reference.
What is the production process of flame retardant fabrics?
The production process of flame retardant fabrics: in simple terms, it is rolling and baking. Specifically, it must first be rolled, that is, firstly through chemical agents, and the second step is ammonia fume. At this time, the ammonia smell of the fabric will be very serious. Ammonia fume enhances the washability of the fabric, but the flame retardant performance is still Not very stable. So the next step is to go through the oxidation process to reduce the smell of ammonia smoke. During the tentering process, the overall performance of the fabric will be much better, and then it will be pre-shrinked to control the shrinkage of the fabric. At this time, the finishing process of the fabric is completed.
Does the flame retardant fabric have heat resistance?
There are many types of flame retardant fabrics. According to the needs of different industries, flame retardant fabrics with different functions are used. Some fabrics with heat resistance are not available. Some fabrics have heat resistance. Basically, the fabrics with heat resistance are aramid flame retardant fabric and acrylic flame retardant fabric. They are often used by workers who work in high temperature environments. Special ratio textile acrylic flame retardant fabrics are also It has different levels of anti-arc performance.
What are the commonly used flame retardant fabrics?
▲Flame retardant acrylic fabric: flame retardant acrylic fiber, also known as modified acrylic fiber, modified acrylic fiber, the fiber itself is flame retardant, this flame retardant fabric is soft and flexible in texture, feels fluffy and has a wooly feel, and it has good warmth , Suitable for winter clothes and spring and autumn work clothes.
▲Nylon flame retardant fabric: Nylon flame retardant fabric is made of 88% cotton fiber and 12% nylon fiber blended fabric. This kind of fabric has extremely strong abrasion resistance and wrinkle resistance, excellent moisture absorption and breathability and high strength.
▲Elastic flame retardant fabric: The elastic flame retardant fabric is made of 95% cotton fiber and 5% spandex silk. Because the spandex yarn is added to the fabric to make it elastic, its taking performance and elasticity are better, and it is not easy to wrinkle.
▲Aramid flame retardant fabric: Aramid fiber itself has the characteristics of non-combustibility, excellent electrical insulation, outstanding chemical stability, excellent mechanical properties, long-term thermal stability, etc. Excellent fire retardant performance, anti-arc performance, chemical corrosion resistance, thermal protection performance, wear resistance and tear resistance.
▲CVC flame-retardant fabric: CVC flame-retardant fabric is a blend of more than 60% cotton fiber and less than 40% polyester fiber. In addition to the excellent characteristics of cotton fiber, it also has the good elasticity of polyester fiber. Resilience, clean fabric, good anti-wrinkle performance, durable.
▲Cotton flame-retardant fabric: 100% natural fiber "cotton" woven cotton fabric, it has the characteristics of breathability, moisture absorption and quick-drying, soft hand feel, soft gloss, while retaining cotton fiber The characteristics of anti-static ecological environment protection.
How to determine the flame retardant properties of fabrics?
Judging from the burning rate of the flame retardant cloth. That is, the flame-retardant fabric is contacted with the flame for a period of time according to the prescribed method, then the flame is removed, and the time when the fabric continues to burn with flame and flameless, and the degree of damage to the fabric is measured. The shorter the flame burning time and the flameless burning time, the lower the degree of damage, the better the flame retardant performance of the fabric; otherwise, the poor flame retardant performance of the fabric.
What is the general classification of functional flame retardant fabrics?
Cotton flame retardant fabrics, flame retardant antistatic fabrics, cotton and nylon flame retardant fabrics, CVC flame retardant fabrics, acrylic flame retardant fabrics, anti-mosquito fabrics, acid and alkali resistant fabrics, UV resistant fabrics, multifunctional flame retardant fabrics, oil resistant Water fabric and so on.
How to buy high-quality flame retardant fabrics?
▲ Try to select large enterprises and well-known manufacturers. The after-sales service of such manufacturers is guaranteed, and problems can be solved in time when problems arise.
▲You must have your own testing laboratory and complete all reports and tests. In this way, the quality of the flame retardant fabric produced can be guaranteed to a greater extent.
▲If necessary, be able to visit the site as much as possible. Some merchants like to exaggerate the facts on the Internet. Those who do not have factories and laboratories like to use pictures from other companies to brag about themselves. Customers must make more comparisons and try to inspect whether they have production qualifications before placing orders.
▲Customer feedback is very important. The company itself advertises that there will never be a loud voice from the customer. It is really good that the customer says good.
