Maximize Moisture Wicking in FR Shirts for Long Shifts [Guide]

Employees in high-risk fields such as electricity, construction, and manufacturing often need to work long hours. These long shifts require physical work and can lead to an increase in sweating, especially in warm conditions. Flame resistant (FR) shirts that have moisture wicking properties are made to keep workers safe and dry by pulling sweat away from the skin. Despite this though, many workers do not optimize the moisture wicking properties of their shirts, which in turn reduces comfort and safety. This blog aims to provide the worker with actionable strategies to maximize the comfort of their long shifts in FR shirts with moisture wicking. This will help them stay dry, safe and concentrated on the job at hand.

Select the Correct FR Shirts with Moisture Wicking  

The first step is the selection of high quality FR shirts with moisture wicking meets the industry standards. Keep in mind, not all FR shirts have these attributes. Search for FR shirts with moisture wicking, and made from synthetic blends like polyester or nylon mixed with FR fibers. Those fabric blends are designed with capillary action in mind, meaning, they draw sweat from the skin and allows for evaporation in the outside surface of the fabric. Do not consider cotton FR shirts, cotton absorbs moisture and keeps it. You will feel damp and heavy, which is not enjoyable. Fabric weight is essential as well; the lighter weight FR shirts with moisture wicking are optimal for prolonged shifts in heat because they allow quicker evaporation. Make sure is the shirt fits just right. Too snug will obstruct the air flow and too loose decreases contact with the skin and moisture transfer.

Pair FR Shirts with Moisture Wicking with Proper Base Layers

A properly selected base layer strengthens the FR shirts with moisture wicking. Choose a thin moisture wicking base layer made with FR compatible materials—this base layer works on the frontline of defense by wicking sweat from the skin and transferring it to the outer FR shirt with moisture wicking. Never wear a cotton base layer under FR shirts with moisture wicking. Cotton base layers will trap sweat and stop the FR shirt from functioning properly. The base layer should be close-fitting to maximize skin surface contact and should be free of any loose threads or seams to prevent skin irritation under high/long workload. For some workers on stickiest of warm days without any base layers, wearing comfort and moisture wicking FR shirts with moisture wicking is a must. Make sure to wear a shirt that is clean and has no residues that will clog the pores of the fabric.

Cleaning to Preserve Moisture Wicking in FR Shirts  

Cleaning correctly will help keep moisture wicking FR shirts in good condition. Dirt, sweat, and detergent build-up over time and clog the fabric and reduce the moisture wicking performance. Wash FR shirts in a temperature safe for the fabric and use a mild, unscented detergent. Don’t use harsh detergents, fabric softeners, or bleach, as these will destroy the moisture wicking coating and FR fibers. Never use dryer sheets, as they cause the fabric to become waxy and block moisture penetration. Use low heat in the dryer or let the shirts air dry to avoid high heat, which will shrink the shirt and ruin moisture wicking. High heat will also ruin the fabric. FR shirts with moisture wicking need to be checked for stains or residue. If they have stains and residue, they need to be rewashed again before long shifts.

Optimizing Care and Wear Habits on Shifts

There are little things we can do on long shifts that can make a difference in how well an FR shirt with moisture wicking works. Heavy lotions, oils, and sunscreens can negatively affect moisture wicking. If sunscreen must be used, pick a light, non-greasy sunscreen and allow time for it to dry before putting on the FR shirt with moisture wicking. During a break, try to step into the shade where you can unbutton your shirt, encouraging airflow and evaporation. If your shift is longer than 8 hours, pack an extra FR shirt with moisture wicking. Midshift, you can change into a clean, dry shirt, which will help with comfort and moisture wicking performance. Avoid adding extra layers over the FR shirt with moisture wicking, as heat and moisture will get trapped, which will counter the shirt’s purpose.

Store FR Shirts with Moisture Wicking Correctly

The way you store an FR shirt with moisture wicking between shifts can preserve the moisture wicking functionality. Never fold and store a damp FR shirt with moisture wicking as mildew can form and destroy the fabric. The shirt must be dried completely and stored in a cool, dry, and well ventilated area. Do not hang the shirt in the direct sunlight as it can dry out the fabric, fade it, and weaken the moisture wicking coating. Make sure to use hangers with wide shoulders to avoid the fabric stretching, which can change its fit and lessen the contact with the skin. If you are going to store multiple FR shirts with moisture wicking, do not overcrowd the closet. By storing the shirts, to ensure they are ready to maximize moisture wicking performance the next long shift.
