Flame-retardant protective clothing refers to a type of protective clothing that prevents itself being ignited, burned smoldered within a certain period of time after being exposed to flames hot objects. It belongs to both conventional clothing labor protection products. The product quality requirements include both conventional clothing requirements special flame retardant protection requirements. For fire-resistant flame-retardant protective clothing with higher more functional requirements, this standard is only applicable to users wearing flame-retardant clothing in places with open flames, sparks, molten metals operating flammable substances fire risks. It does apply to Flame-retardant protective clothing is worn during fire rescue. Due to its universality particularity, there are many standard technical requirements. Today, we mainly share several important performance requirements. Student school uniform customization
In summary, the main requirements are: flame retardant performance requirements; safety performance requirements; wearing performance requirements; aesthetic performance requirements. The flame retardancy index mainly includes continuous burning time, smoldering time, damage length, melting, titer thermal protection performance. Sewing thread, accessories accessories are an indispensable part of clothing.
As an important part of flame retardant protective clothing, it also has special requirements for flame retardants. The standard requires that the sewing thread must be melted burned; the materials of buckles, hooks, zippers should be non-meltable, flammable, easily deformed. If needed, their surface should be covered with flame-retardant clothing materials; metal parts have strong thermal conductivity are easy to burn the skin. It cannot be in direct contact with the body; if rubber band materials are used, the covered material must be flame-retardant must be used when lining, the lining must be melted; when using reflective materials other materials, these materials must be flame-retardant materials. In many cases, rolling baking other finishing processes are used.
Therefore, high-intensity processing conditions such as high temperature high radiation are required. However, side reactions may occur during the baking process, causing fiber degradation, oxidation, hydrolysis, even thermal damage, which will change the original normal wearing properties of textiles, such as reduced strength, poor moisture permeability, fabric hardening, which will affect the durability of clothing. Sex comfort. Therefore, flame-retardant protective clothing has common wearing requirements, such as clothing pilling, washing size change rate; special environments (high temperature, flame) also have wear requirements, such as thermal stability, structure; there are also wear requirements in the flame retardant process, such as Strength, moisture permeability, stiffness, etc.
The standard of the sewing process starts two aspects appearance, so that the specific requirements of each part of the sewing, the logo, the sleeve, the seam, the crotch is sewn behind the pants, the position of the eyes, the buttonhole button, the placket, the symmetry, the different colors, Flattening, neatness, etc., to ensure excellent craftsmanship, elegant appearance, based on fully embodying its unique use value, users bystanders can enjoy its eyes further increase its added value. In fact, the inspection data in recent years, the unqualified items of flame-retardant protective clothing are mainly concentrated in formaldehyde content color fastness. Test results show that about 10% of protective clothing does meet the requirements of national standards, some even exceed the requirements of national standards by more than three times.
Most of the products that meet the standard are between 100-300mg/kg, which is far 80% of ordinary clothing, even less than 75mg/kg. The main reason is the use of formaldehyde-containing additives in the post-treatment flame retardant process. The solution is to reduce the use of such additives replace them with environmentally friendly additives.
