Essential Garment Quality Tests You Should Know About to Ensure Optimum Wearing Experience

On cold winter days, wearing layers is a smart approach that allows you to adapt to changing conditions. A light down jacket with a wool sweater underneath is a popular choice.

Good-quality clothing not only helps you withstand the cold, but at the same time keeps you cozy and comfortable.  For down, knitted-yarn and woolen garments, some key tests are available to ensure top quality and an excellent wearing experience.

Wool comfort

Knitted-yarn and wool fabrics provide warmth and softness no matter whether you are dry or wet. However, they also have a reputation for prickle. In recent years, an increasing number of knitwear manufacturers and retailers have relied on advanced high-performance tests that can measure the prickle factor in wool, making it the ideal next-to-skin fiber.

Our Wool-comfort Meter, the latest objective testing method for prickle comfort, is now available to ensure all wool and wool-yarn products will be comfortable and free of prickle. The Prickle Factor Test measures the prickle index and provides a grading of the samples. A higher index and lower grading represent a stronger prickle factor, which may impact the level of comfort. This is the first technology to measure different types of yarn, fabric and garment by the proportion of stiff microscopic fibers protruding from the material that might lead to an unpleasant wearing experience.

Down-Fiber Penetration Resistance

When choosing a down jacket, besides feather & down composition and fill rating, it is important to check the penetration resistance of the outer material. A good-quality product with low down/fiber penetration can prevent loss of down/fiber during usage.

Recently, the first Non-destructive Tumbling Method was launched to test full-garment penetration resistance, a test now approved and certificated by the Hong Kong Laboratory Accreditation Scheme (HOKLAS). The new method is applicable to any size of down/feather garment or fiber-stuffed garment. After tumbling, the number of penetrating/protruding down/feathers/fibers on the surface or lining of the tested garment is counted and a rating will be given accordingly. Good-quality products with lower down/fiber penetration will get a higher rating. Compared with other tumbling methods, this testing process is designed to simulate real-life conditions and no cutting of the garment is required.
