Summer is just around the corner—the hottest season of the year. Naturally, this season is prone to fires, making indoor arson prevention particularly important. Yet many people are wondering: How can we effectively prevent fires during summer? I’m sure many of you are curious about this question. In fact, flame-retardant window screens have become increasingly popular these days. Now, let’s join our editor to learn more about flame-retardant window screens!

　 　First, what is flame-retardant window screen?

　　Flame-retardant window screens are made from flame-retardant fabrics and, thanks to the action of heat-insulating and flame-retardant additives, can provide fire-retardant relief. They are now widely used. According to relevant regulations, common decorative materials are classified into four grades based on their combustion performance: Grade A—non-combustible; Grade 1—flame-retardant; Grade B2—combustible; and Grade 3—highly flammable. Only fabrics that meet either Grade A or Grade B1 can be referred to as flame-retardant fabrics.

　 　I. Flame-retardant treatment of fibers

　　Flame-retardant treatment of fibers involves adding flame-retardant agents to combustible yarns such as polyester, nylon, and acrylic, which either inhibit the release of flammable gases during combustion or alter the thermal decomposition process of the fibers, thereby promoting dehydration and carbonization. In some cases, the flame-retardant agents form a non-gaseous layer that coats the fiber surface, effectively blocking access of air.

　　2. Flame-retardant treatment of fabrics

　　Flame-retardant treatment primarily involves surface treatment of fabrics during the textile processing stage to impart flame-retardant properties to the fabric. There are three main processing methods.

Soaking and Impregnation Techniques: This technology is primarily used for processing pajamas, bedding, and other textiles, but it can also be applied to outerwear.

Spraying technology: primarily intended for decorative fabrics and architectural fabrics that require little or no washing.

Coating Technology: This technology is primarily used for processing personal protective equipment and decorative fabrics.

　　 II. Cleaning Methods for Flame-Retardant Window Screens

　　1. To properly clean and maintain flame-retardant window screens, choose the correct detergent.

　　When cleaning flame-retardant window screens, be sure to choose the right detergent. Detergents containing bleach are suitable for cleaning white flame-retardant window screens, but should not be used on colored screens to prevent discoloration. When cleaning white flame-retardant window screens, avoid using detergents with chlorine-based bleach; instead, opt for detergents containing oxygen-based bleach to enhance cleaning performance while protecting the linen fibers.

　　2. The quality of water used to wash flame-retardant linen curtains is crucial.

　　Washing flame-retardant linen window screens also requires water. If the water hardness is too high (i.e., the water contains a high lime content), you’ll need to add a fabric softener—especially when washing dark-colored linen fabrics. Linen has excellent water absorption, so you should increase the amount of water used appropriately during washing. As for water temperature, follow the instructions on the care label attached to the garment; excessively high water temperatures could damage the fabric.

　　That concludes our introduction to flame-retardant window screens. We hope the information provided above has given you a good understanding of these screens. It’s advisable to prepare them in summer to guard against unexpected situations. Of course, you can refer to the information above when cleaning your flame-retardant window screens.
