When choosing running clothes and trousers, we must not choose pure cotton materials, because pure cotton clothes and trousers will adsorb to the body when the human body sweats, causing colds. When buying a running T-shirt, you can look at the tag on the clothing (as shown below). From the tag, you can see that the main ingredients are polyester fiber, spandex, etc.
Commonly used materials include polyester. Polyester and spandex are both polyester fibers, but they have their own advantages. Therefore, when purchasing, please pay attention to the tags on T-shirts and pants, which provide a basic description of the fabric material.
Polyester
Features: high wrinkle resistance, high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid and alkali resistance, good light resistance, and good exposure resistance 1000 hours, strength retention of 60-70%, poor hygroscopicity, difficult to dye, fabric is easy to wash and quick-dry, has good shape retention, and has the characteristics of “wash and wear”.
Uses:
1. Filament: often used as low elasticity yarn to make various textiles;
2. Short fiber: cotton, wool, linen, etc. All can be blended;
3. Industry: tire cord, fishing nets, ropes, filter cloth, insulating materials, etc.
Spandex
Features: The best elasticity, the worst strength, poor moisture absorption, good light resistance, acid resistance, alkali resistance, and wear resistance.
Uses: Spandex is widely used in textile fields and medical fields based on its characteristics, such as underwear, women’s underwear, casual wear, sportswear, socks, pantyhose, bandages, etc. .
Spandex is a highly elastic fiber necessary for high-performance clothing that pursues dynamics and convenience. Spandex can stretch 5-7 times longer than the original shape, so it is comfortable to wear, soft to the touch, wrinkle-free, and can always maintain its original contour.
Main difference
Polyester and spandex are just fabric components and have no fixed color properties. In terms of purpose, polyester is often used in clothing. Polyester is not as ductile as spandex, and its breathability is not as good as spandex. However, the feel and visual effect of polyester are stronger than spandex. In other words, polyester is more suitable for styling, and is commonly seen in suit jackets, shirts, etc., while Spandex is generally not used alone because it has insufficient elasticity. It is often mixed into fabrics to make elastic fibers, which are used to make elastic core-spun yarns and used for socks.
, furniture covers, ski jackets, sportswear, medical fabrics, etc.
