Non woven fabric, with its advantages of lightweight, breathability, and high cost-effectiveness, has already penetrated into every aspect of our lives – masks, shopping bags, home soft furnishings, outdoor protective equipment, and even industrial filter materials, where its presence can be seen. However, when many people buy non-woven products, they will be fooled by the merchants’ propaganda of “anti-aging, durable, and not easy to break”. The “anti-aging style” that they bought at a high price will soon become yellow, brittle, and broken. In fact, it is just a “superficial skill”.
Many people mistakenly think that “thick” non-woven fabric is equal to “anti-aging”, or “deep color” is more durable, but this is actually a mistake. The core of real anti-aging non-woven fabric lies in the material and process, rather than the appearance. Today, I will teach you a trick: without the need for professional equipment, you can quickly make judgments at home, easily avoid merchant tricks, and avoid wasting money.
Let’s first understand: What are you afraid of when non-woven fabric “ages”?
To judge whether non-woven fabric is really anti-aging, you must first understand what its “natural enemy of aging” is. The main raw materials for non-woven fabrics are high molecular weight materials such as polypropylene and polyester, and their aging is mainly caused by “photo aging” and “thermal aging”. Among them, ultraviolet rays (UVA/UVB) in sunlight are the number one culprit that accelerates their aging.
Ordinary non-woven fabrics are not added with anti-aging agent. After long-term exposure to the sun and high temperature environment, the internal molecular chains will be damaged by ultraviolet rays, and three obvious symptoms will appear: yellowing and brittle, the original white or bright color will become dim and yellow, and it will feel hard and brittle when touched by hand; Easy to break, slight pulling can cause cracks or even direct tearing; Performance degradation, such as waterproof and filtering non-woven fabrics, will lose their original function after aging, resulting in water leakage and decreased filtering effect.
The “real anti-aging” non-woven fabric will add special anti-aging agents (such as hindered amines and benzotriazoles) in the production process, which can effectively absorb ultraviolet rays, inhibit molecular chain breakage, and delay the aging speed; On the other hand, the “surface kungfu” model either does not add anti-aging agent, or only adds a small amount of low-quality anti-aging agent, or even just dyes and thickens the surface to disguise itself as a “anti-aging model”, which will be exposed in 1-3 months.
Core move: it can be measured at home and quickly distinguish “real anti-aging” from “superficial kungfu”
No need for professional testing equipment, just prepare a household UV lamp (nail lamp, money detector lamp can be used, wavelength 365nm is the best), and add a small non-woven fabric sample. The results can be obtained in 30 seconds, making it easy for beginners to operate. The steps are unbelievably simple.
Specific operational steps
1. Prepare samples: Cut a small piece (about 2cm x 2cm) from the non-woven fabric product to be tested, and try to choose an inconspicuous part to avoid damaging the product; Prepare a known ordinary non-woven fabric (such as the inner layer of a cheap mask or a regular shopping bag) as a control.
2. Testing environment: Turn off the room lights, keep the environment dim, avoid other light interference, and ensure that the ultraviolet lamp can function properly.
3. Exposure test: Aim the ultraviolet lamp at two non-woven fabric samples, maintaining a distance of 5-10cm, and continue to irradiate for 30 seconds (if it is a nail lamp with high power, it can be irradiated for 15 seconds).
4. Observation results: After the irradiation is completed, comparing the color changes of the two samples, the answer is clear at a glance.
Result judgment: distinguish true from false anti-aging
Real anti-aging nonwoven fabric: after irradiation, the color is basically unchanged, and the original color is still maintained. The texture of hand touch is unchanged, and there is no sign of brittleness or hardness. Because of the addition of qualified anti-aging agent, it can effectively resist ultraviolet radiation, and will not change significantly in a short time.
Surface kung fu non-woven fabric: After irradiation, it will quickly turn yellow, darken, and even have a slight crispy feeling. It will peel off with a gentle pinch by hand and is easy to break when pulled. This kind of non-woven fabric is either not added with anti-aging agent, or the anti-aging agent is inferior, unable to resist ultraviolet rays. A short time of irradiation will expose the aging hidden danger.
Supplementary note: if there is no ultraviolet lamp, you can also use the “exposure test” to help judge – put two samples in direct sunlight for 24 hours, and the real anti-aging style will basically not deform or yellow, and the surface kungfu style will obviously become brittle, yellow, or even crack.
Avoid the tricks of three merchants and buy non-woven fabric to avoid pitfalls
In addition to using the above methods for detection, it is also necessary to avoid the three common tricks of merchants and avoid being deceived by “superficial efforts” and wasting money.
Routine 1: Only promote “thick” without anti-aging agent. Many businesses will emphasize that “thickened non-woven fabrics are durable and resistant to manufacture”, but the thickness has no direct relationship with anti-aging – ordinary thickened non-woven fabrics, even thicker, without anti-aging agent, will still be brittle in long-term exposure, but because of the increase in thickness, people mistakenly think they are durable.
Routine 2: Use dyeing to cover up the hidden dangers of aging. Some businesses will dye the non-woven fabric into dark color (black, dark gray), claiming that “dark color is more anti-aging”. In fact, only dark color can cover the traces of yellowing, which is essentially ordinary non-woven fabric. Without anti-aging agent, it will still be brittle and broken after a period of time.
Routine 3: False promotion of “anti-aging” without any test report. When buying, the merchants boasted that “it can be used for 3 or 5 years without aging”, but when you asked to see the anti-aging test report, they were unable to provide it. The real anti-aging non-woven fabric will have an authoritative test report, clearly indicating the anti-aging grade and service life.
Suggestions for different scenarios, choose the right anti-aging non-woven fabric as needed
Non woven fabrics with different uses have different demands for “anti-aging”. Combining the above judgment methods, they can be purchased on demand, which will not waste money, but also meet the use needs.
1. Outdoor scene (sunscreen, outdoor protective cloth, shopping bag): the real anti-aging model must be selected. During the test, ensure that there is no obvious change after ultraviolet radiation, and give priority to the products marked with “anti-aging agent added” and “anti UV”, otherwise they will be damaged after long-term exposure.
2. Home scene (curtains, sofa covers, storage bags): if it is placed in the direct sunlight position (such as balcony curtains), the real anti-aging style should be selected; If it is placed indoors in a place without direct sunlight, ordinary non-woven fabrics can be used, and it is unnecessary to spend high prices to buy anti-aging products.
3. Disposable scenes (masks, disposable gloves, disposable shopping bags): no need to pursue anti-aging, just focus on air permeability and safety. After all, such products have a short service life, and do not need to consider long-term aging.
4. Industrial scenario (filter material, protective cloth): high-level anti-aging products must be selected, and authoritative test reports need to be checked to ensure stable performance, no aging damage and no impact on use safety under long-term sunshine and high temperature environment.
In fact, judging whether the non-woven fabric is really anti-aging requires no complicated operation at all. Remember this UV test method, and you can easily avoid “surface kungfu” without wasting money. No amount of business routines can meet the actual test results – the real anti-aging non-woven fabric can withstand the test of ultraviolet light, and it will be used for a long time and more worry free; And the surface kung fu style will eventually reveal its true form during use.
Next time you buy non-woven fabric products, don’t be misled by the promotion of “thick, dark, durable”. Cut a small sample and test it first. You can distinguish between genuine and fake in 30 seconds, which saves money and worry, and you no longer have to pay for inferior non-woven fabrics!
