What is the production process of flame retardant tarpaulin


Flame retardant fabrics and flame retardant tarpaulins […]

Flame retardant fabrics and flame retardant tarpaulins are not not on fire, but ordinary fabrics have the performance of preventing flames from continuing to spread after flame retardant finishing, and cannot continue to burn when the flames are removed. It is an 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, Yulong The editor has compiled some common problems of flame retardant fabrics 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 be rolled first, 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 considered complete.

Does the flame retardant tarpaulin have heat resistance?
There are many types of flame retardant tarpaulins. According to the needs of different industries, flame retardant tarpaulins with different functions are used. Some fabrics with heat resistance are not available. Some fabrics have heat resistance. Basically, heat-resistant fabrics are aramid flame retardant fabrics and acrylic flame retardant fabrics. They are often used by workers who work in high temperature environments. Special proportions of acrylic flame retardant fabrics are also textiles. 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 has a soft and flexible texture, a fluffy feel and a wooly feel, and at the same time, it has good thermal insulation, Suitable for winter clothes, 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. Due to the elasticity of the spandex yarn added to the fabric, it has better wearability and elasticity and is less prone to wrinkling.
Aramid flame-retardant fabric: Aramid fiber itself has the characteristics of non-combustibility, electrical insulation, outstanding chemical stability, excellent mechanical properties, long-term thermal stability, etc. Therefore, aramid fabric has extremely excellent fire resistance Combustion performance, anti-arc performance, chemical corrosion resistance, thermal protection performance, wear resistance and tear resistance.
CVC flame retardant fabric: CVC flame retardant fabric is blended with 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 and recovery of polyester fiber Sex, the fabric is crisp, the wrinkle resistance is good, and it is durable.
100% cotton flame retardant fabric: 100% natural fiber "cotton" woven cotton fabric, it has the characteristics of breathability, moisture absorption, quick drying, soft feel, soft luster, while retaining the Antistatic ecological and environmental protection characteristics.


How to determine the flame retardant properties of fabrics?
Judging from the burning rate of the flame retardant tarpaulin. That is, the flame retardant fabric is contacted with the flame for a period of time according to the prescribed method, and 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.
