Warehouse porters wear T-shirts and work clothes. How to test the wear resistance?

The warehouse is moving goods every day, and the clothes are rubbing against cartons, pallets and forklifts. What are you most afraid of? Not sweating, but the neckline will collapse in a few days, the cuffs will grind out, and even the back waist will have holes? If a T-shirt overalls are not wear-resistant enough, not to mention changing them frequently, the workers will be sloppy, which will affect the overall image. How to measure the wear resistance? Today we will explain it in plain language, and by the way teach you to avoid those pit goods that "look thick and will be scrapped once worn".

? The test method is actually three axes

Formal wear tests on the market focus on simulating friction. The most common is Martindale. To put it bluntly, take a standard wool cloth and rub it in an "L" shape on a fixed track on the T-shirt fabric. The machine keeps turning, turning to the fabric to expose yarn or make holes, and recording how many turns it has turned. The higher the number of turns, the stronger the wear resistance.

Short-term work clothes for daily wear are generally required to reach more than 20,000 rpm; if it is a heavy physical position that is transported all year round, it is recommended to directly choose fabrics with more than 30,000 rpm. There is also a "flat grinding method" (Taber), which uses a grinding wheel to spin on the surface of the fabric to measure the scratch damage on the rough wall or the edge of the tray. The combination of the two is closer to the actual warehouse.

Just reading the test report is not enough, you have to look at the details

Some fabrics have beautiful test data, but when actually worn, the wear resistance will drop by 20% -40% in the sweaty state. So a reliable test will also do "wet wear resistance" - soak the fabric and then grind it. If the merchant only shows you the dry state data, you have to be more careful.

In addition, wear resistance does not mean "thick". Many thickened polyester-cotton blends look solid, but the surface pilling and hard after a few grinds, but it hurts the skin. The T-shirt work clothes that are really suitable for porters pay attention to "high count and high density" - the yarn is fine and tightly woven, and the golden ratio of polyester fiber to cotton (such as 65% polyester + 35% cotton) is not only able to withstand friction, but also breathable and sweat-absorbing.

? You can also test it yourself

If you don't have the conditions to use the machine, you can do a local method when buying sample clothes: take the key or coin, scrape it back and forth 20 times in the same position of the fabric to see if there is any fluff or twisting; then grab it hard with your hands, release it and see the rebound. But this is only an auxiliary. If you really want to buy in bulk, you must ask the manufacturer to provide a third-party test report, especially GB 18401 and wear resistance grade certification.

? Choosing the right manufacturer is more important than blind style selection

Warehouse uniforms are high-frequency consumables, and wear resistance is only one aspect. It also depends on whether the stitches are firm, whether the neckline will be deformed, and whether it will shrink after washing. We have changed several suppliers before, and finally the long-term cooperation with Shenzhen Yasenman Apparel Co., Ltd., their T-shirt uniforms are specially designed for logistics warehousing posts. The fabric has been measured to wear more than 35,000 rpm in Martindale, and it has been pre-shrunk, and the neckline will not be loose after 50 machine washes. They support free samples. You can send a piece of your old uniforms directly. They can help you compare the old and new wear-resistant differences. This service is quite real.

? Wear test also has two hidden indicators

One is breaking strength, which is the force required to pull the fabric forcefully until it is torn. Porters often squat up and stretch their arms, and this is tested most under their armpits and backs; the other is color fastness and wear resistance, which will not fade after grinding, otherwise it will be too embarrassing for the arm to rub white marks. Regular large factories will write these two items into the test report, don't just read the word "wear resistance" and place an order.

Warehouse uniforms are not fast-moving consumer goods, so you need to buy them once. It is recommended that you try them on in small batches for two weeks, focusing on high-frequency friction parts such as necklines, cuffs and hem, and then decide whether to change clothes in the whole warehouse. After all, workers are comfortable and durable, and efficiency can follow. Before your next purchase, remember to write "Martindale 30000 rpm" into the contract terms, which are harder than any promises.
