Flame retardant protective clothing fabric selection requirements?

High-quality flame retardant protective clothing should meet the following requirements:
(1) First of all, consideration should be given to protection and safety. New flame-retardant protective clothing should have excellent protection standards and degree of protection. That is to say, the most important function is to meet the safety needs of the staff.
(2) good wear resistance. Apparel should be applied to rescue workers in the fire caused by a variety of complex sports wear and tear. $ o
(3) Durability, long-term repeated use.
(4) good comfort. Has good breathability and moisture permeability. This is particularly important for fire rescue, work in comfortable conditions.
Not only can extend working hours. But also can improve work efficiency, reduce work errors and so on. New flame retardant clothing development trend is. From a single emphasis on risk protection to pay attention to ergonomic features and comfort changes. Give full play to the potential of the new detection technology and data consolidation. Designed to be more comfortable. Protective More comprehensive high temperature comfort flame retardant protective clothing.

Flame retardant protective clothing fabric choice question:
Flame retardant protective clothing combines the advantages of flame retardance and comfort. In the design of the fabric first select the desired performance with different fabrics. Use fabric compound technology. Such as laminating technology. Without damaging the function of each component, simply and effectively to achieve the function of superposition and efficiency. So that the new flame retardant clothing as a multi-purpose carrier, providing flame retardant, moisture permeability, waterproof and other comprehensive protection at the same time. Due to the multi-layer fabric will increase the weight of clothing needs. Therefore, in the design of coordination between protection and comfort performance of the relationship between. Reduce the wearer's weight.
    1, fire retardant layer;
Flame retardant fire retardant clothing for the outermost layer. It is in direct contact with the scene. In the application will be subject to a variety of wear and tear, hooking effect, and thus flame retardancy, abrasion resistance, tear resistance will become an important factor in this level of design. Plain weave basalt fire-resistant fabric is available, which is made from continuous basalt fiber spun yarns (7-9) m. Tested. The surface properties of the fabric can achieve the above requirements of the flame retardant, wear-resistant, tear-resistant, anti-hook performance. In order to achieve more excellent results. The basalt fire retardant fabric can be coated with high temperature ** The fabric has a non-flammable, high temperature, non-toxic gas emissions, heat insulation, no melt dripping, high strength, no shrinkage and so on. therefore. Fire retardant clothing can be qualified as the outer layer of fire protection needs. l
2, waterproof breathable layer
There are many ways to achieve waterproof and breathable fabrics, such as: high-density fabric structure design, waterproof and moisture-permeable coating finishing, waterproof and moisture-permeable film composite processing waterproof and moisture-permeable film which is a weight without burden. And excellent performance of the material. The film is a selective barrier between two phases. The external impetus to the process of delivery can be a pressure differential. Concentration or temperature difference. The waterproof and breathable film used in the composite fabric should have a good choice of permeability. Waterproof breathable film can generally be divided into microporous waterproof breathable film, non-porous waterproof breathable film, two-component waterproof breathable film 3 kinds. Currently more mature technology for the PTFE microporous film (referred to as PTFE) developed by the tensile method of the basic properties of PTFE microporous film in Table 1.
3, insulation layer
Insulation layer in the flame retardant protective clothing fabric of the middle layer. Mainly to isolate the thermal environment of the air heat conduction, to prevent the role of staff burns. Through experimental analysis found. This layer of flame retardant protective clothing thermal radiation performance, thermal conductivity, moisture permeability are significant impact. The choice of materials on the use of far-infrared polyester fiber, the design weight of 180 ~ 200g / m2, the thickness of 5 ~ 6 mm to achieve the performance requirements. of course. Other flame retardant fibers can also be used for this layer design. Such as Nomax. Aramid and so on.
4, lining
In the new flame retardant protective clothing to join the lining layer is mainly from the comfort point of view. Can prevent the outer fabric and the human body contact directly produce a sense of itching. And if the layer material selection, but also can achieve good perspiration effect. So that staff wearing fire-retardant protective clothing more comfortable. You can consider the choice of plain weave viscose fabric or cotton fabric. Thickness of about 0.2mm. Yarn count can be selected between 18 ~ 25 tex.
