Can polyester air covered yarn withstand high temperatures and frequent washing?Polyester air covered yarn is a type of yarn that is made by covering a polyester filament or staple fiber with a layer of air-filled or air-textured fibers. It is known for its softness, strength, and durability. However, when it comes to its ability to withstand high temperatures and frequent washing, there are a few important factors to consider.
Firstly, polyester is a synthetic fiber that has a relatively high melting point. It typically withstands temperatures up to 180-190 °C (356-374 °F) before it starts to melt. This means that in most normal washing conditions, polyester air covered yarn should not be exposed to temperatures that are high enough to cause any damage.
However, it is important to note that excessive heat or heat from other sources, such as ironing at high temperatures or exposure to direct sunlight for a prolonged period, can still cause the polyester fibers to weaken or melt. Therefore, it is always advisable to follow the care instructions provided by the manufacturer to avoid any potential damage.
In terms of washing frequency,
polyester air covered yarn is generally considered to be quite durable and can withstand frequent washing. Polyester fibers have a high resistance to shrinking, stretching, fading, and wrinkling. They also have excellent color retention properties, making them suitable for garments and textiles that require regular washing.
It is worth noting that polyester yarn may not absorb moisture as well as natural fibers such as cotton or wool. This means that it may take longer to dry, especially if the yarn is used in a fabric with a high density or thickness. Therefore, it is recommended to avoid leaving wet polyester garments or fabrics for extended periods, as this may lead to the development of mold or mildew.
What are the differences in performance between spun polyester and air covered polyester yarn?Spun polyester and air covered polyester yarn are two popular types of polyester yarns used in the textile industry. While both are made from polyester fibers, they differ in terms of production process, characteristics, and performance. Here are some of the key differences in performance between spun polyester and air covered polyester yarn.
1. Production process: Spun polyester yarn is manufactured through the spinning process, which involves twisting individual polyester fibers together to form a single yarn. On the other hand, air covered polyester yarn is produced using a more complex method called air covering. In this process, a core yarn is wrapped with a second yarn using compressed air. This gives the yarn a different structure and properties compared to spun polyester yarn.
2. Strength and durability: Air covered polyester yarn is known for its superior strength and durability compared to spun polyester yarn. The air covering process enhances the strength of the yarn by tightly wrapping the second yarn around the core yarn. This makes air covered polyester yarn more resistant to breakage and deformation, making it suitable for applications that require high strength and durability such as industrial fabrics, upholstery, and outdoor textiles.
3. Softness and comfort: Spun polyester yarn is typically softer and more comfortable compared to air covered polyester yarn. The spinning process used to manufacture spun polyester yarn creates a yarn structure that is softer and more pliable, making it suitable for applications that require a comfortable feel against the skin, such as clothing and bedding.
4. Bulkiness and elasticity: Air covered polyester yarn has a higher bulkiness and elasticity compared to spun polyester yarn. The air covering process creates air pockets between the core and wrapping yarn, giving the yarn a fluffy appearance and a higher loft. This increased bulkiness and elasticity make air covered polyester yarn suitable for applications that require volume and stretch, such as knitwear, socks, and hosiery.
