Durability
Strength: Polyester Yarn has obvious strength advantages. Its fiber structure is tight and the intermolecular force is strong, which makes the yarn have high strength. When stretched by external force, it can withstand a large load without breaking easily. It can maintain good integrity both in the weaving process and in daily use. For example, when making industrial fabrics, outdoor tents and other products with high strength requirements, Polyester Yarn has excellent durability. In contrast, the fiber strength of cotton yarn is relatively low. Under the action of large external forces, the fiber is prone to breakage, which affects the service life of the fabric.
Abrasion resistance: Polyester Yarn has excellent abrasion resistance. During frequent friction, the yarn surface is not easy to pilling and can maintain the appearance and structure of the fabric for a long time. This allows clothing, home textiles and other products made of polyester yarn to maintain a good texture after long-term use and washing. After repeated friction, the fibers of cotton yarn are easily worn and broken, resulting in fluff and pilling on the surface of the fabric, which not only affects the appearance, but also reduces the thickness and thermal insulation performance of the fabric.
Wrinkle resistance and dimensional stability: Polyester Yarn has good elastic recovery ability. The fabric is not easy to wrinkle and deform after wearing and washing, and can always maintain good flatness and dimensional stability. Even after a long period of squeezing or rubbing, the clothes can be restored to their original state as long as they are hung or laid flat for a period of time. Cotton yarn has poor wrinkle resistance. Clothes are prone to wrinkles during wearing, and need to be ironed frequently to restore flatness. They are also easy to shrink after washing, causing the size of the clothes to change.
Comfort
Breathability: Cotton yarn has a natural porous structure, and air can freely shuttle between fibers. It has good breathability, allowing the skin to "breathe" and make people feel comfortable. Especially in summer or when exercising, wearing cotton clothes can keep people cool. Polyester Yarn has relatively poor air permeability. Its molecular structure is tight and air cannot pass easily. However, with the continuous advancement of textile technology, some new polyester fibers have improved air permeability to a certain extent by changing the cross-sectional shape of the fiber and the organizational structure of the fabric.
Hygroscopicity and dry feeling: Cotton yarn has strong hygroscopicity and can quickly absorb sweat and moisture from the skin surface to keep the skin dry. However, it dries slowly after absorbing moisture, and wearing wet clothes for a long time will make people feel uncomfortable. Polyester Yarn has very low hygroscopicity, and its moisture regain is generally around 0.4%. Therefore, it is not as good as cotton yarn in terms of moisture absorption and perspiration, but it has quick drying properties. Even in the case of heavy sweating, it can dry quickly and will not let people wear wet clothes for a long time.
Softness: Cotton yarn is soft and comfortable to the touch, especially yarn made of long-staple cotton, which is softer and very suitable for close-fitting wear. Polyester Yarn itself is relatively hard, but through special processing, such as softener treatment, fiber refinement, etc., it can also obtain better softness to meet different usage needs.
In terms of durability, Polyester Yarn performs better and is more suitable for clothing and items that need to be washed frequently and are subject to greater wear and tear. In terms of comfort, cotton yarn has certain advantages, especially in terms of breathability and softness, and is more popular among consumers who pursue a comfortable wearing experience.
