Application And Innovation Of Polyester Yarn in Knitwear

2. Application Status Of Polyester Yarn In knitted Clothing

 

Routine application
Basic style: In a large number of basic knitwear, such as ordinary T-shirts, sports vests, etc., polyester yarn is often used. Its high strength characteristics make the clothing durable and not easy to break during daily wear and washing. For example, the basic solid color T-shirts of some fast fashion brands will use a certain proportion of polyester yarn blended with other fibers to reduce costs and ensure the durability of the clothing.

 

Sports wear: Because polyester yarn has low moisture absorption, it can quickly transfer sweat from the skin surface to the outer layer of the fabric, accelerate evaporation, and keep the skin dry, so it is widely used in sports knitwear. Like professional running T-shirts, fitness tights, etc., most of them contain polyester components. Many of the well-known sports brands of hygroscopic sweat-wicking series sportswear are made of polyester yarn as the main raw material.

 

Blending application
Blended with cotton: cotton fiber has good moisture absorption and soft feel, but the elasticity and wear resistance are relatively weak. The blend of polyester and cotton can make up for each other's weaknesses. This blending method is common in knitted underwear, home wear and other products. For example, common polyester-cotton blended pajamas have the comfortable touch of cotton, but also have the wrinkle resistance and

durability of polyester.

 

Blend with spandex: Spandex has high elasticity, and when blended with polyester, it can give knitted clothing excellent elastic recovery performance. In tight knit clothing, such as yoga clothes, jeans, etc., this blend fabric is widely used. When wearing such clothing, it can fit the curve of the body and is not easy to deform during exercise.

3.The Development Trend Of Polyester Yarn In Knitted Clothing

 

Functional demand growth
Consumers' expectations for the functionality of knitted clothing continue to increase. In addition to the common functions of hygroscopic sweating, antibacterial and deodorant, the future will also pursue more special functions such as anti-static, anti-mosquito bites, self-cleaning and so on. For example, in some outdoor knitwear, the antistatic function can reduce dust adsorption and improve the cleanliness of wearing; Mosquito bite protection provides additional protection for outdoor activities.

 

Sustainable development
With the enhancement of environmental awareness, sustainable development has become an important trend in the application of polyester yarn in knitted clothing. On the one hand, the production enterprises will be committed to the research and development and use of recyclable polyester yarn, reducing the dependence on native resources; On the other hand, optimize the production process, reduce energy consumption and pollutant emissions. For example, some brands have introduced knitted clothing made with recycled polyester yarn, which meets consumers' demand for environmental protection while maintaining the performance of the product.

 

Intelligent development
Intelligence is an important development direction of knitted clothing in the future. Polyester yarn is expected to be combined with smart materials to develop knitted clothing with intelligent adjustment functions. For example, by adding special heat-sensitive materials to the polyester yarn, the clothing can automatically adjust the air permeability according to the ambient temperature, providing consumers with a more comfortable wearing experience.

 

4. Innovative Application Of Polyester Yarn In Knitted Clothing

 

Functional innovation
Moisture absorption and perspiration function: Through special fiber section design and surface treatment technology, further optimize the moisture absorption and perspiration performance of polyester yarn. For example, the use of special-shaped cross section fiber, increase the space between the fibers, accelerate the speed of water conduction; Hydrophilic treatment was carried out on the fiber surface to improve the hygroscopic ability. Knitted sportswear made of new hygroscopic and perspirant polyester yarn can quickly discharge sweat during high-intensity exercise, keep the body

dry and improve exercise comfort.

 

Antibacterial and deodorant function: The antibacterial agent is evenly loaded on the surface of the polyester yarn by using nanotechnology, or the antibacterial masterbatch is added to the polyester melt by the method of blending silk, so that the polyester yarn has long-lasting antibacterial and deodorant properties. This yarn is often used in the production of underwear, socks and other knitted clothing, can effectively inhibit the growth of bacteria, reduce odor generation, to provide consumers with a healthy wearing environment.

 

Anti-ultraviolet function: Anti-ultraviolet agents are added in the production process of polyester yarn, such as titanium dioxide, zinc oxide and other nanoparticles, which can absorb or reflect ultraviolet light, thereby protecting human skin from ultraviolet damage. Knitted outdoor clothing made from this yarn, such as sunscreen clothing, can provide consumers with reliable sun protection.

 

Comfort innovation
Improve the softness: By improving the spinning process and finishing technology, make the polyester yarn feel more soft. Using low temperature plasma treatment technology, the surface of polyester yarn is etched and modified to increase the roughness of fiber surface and improve the friction between fibers, so as to make the yarn more soft and smooth. This soft polyester yarn is used to make knitted baby clothes and underwear, which can enhance the comfort of wearing.

 

Air permeability improvement: Develop polyester yarn with porous structure to increase air circulation channels and improve the air permeability of knitted clothing. Hollow fiber technology is used to form a hollow structure inside the fiber, which can not only increase the air permeability, but also improve the thermal insulation performance. The application of this yarn in winter knitted warm clothing can not only ensure the warm effect, but also avoid the stuffy feeling caused by air permeability.

 

Fashion innovation
Color and luster: The use of new dyeing technology and fiber modification technology, so that polyester yarn presents a rich variety of colors and unique luster. The polyester yarn with bright color and high color fastness is produced by adding pigment to the polyester melt before spinning. At the same time, by changing the cross section shape and surface roughness of the fiber, the gloss of the yarn can be adjusted, such as the triangular cross section fiber can produce a silk-like luster to meet the needs of consumers for fashionable appearance.

 

Texture and pattern: Through the innovation of knitting process, the use of polyester yarn to create a variety of unique textures and patterns. Use jacquard knitting technology to weave exquisite patterns on the surface of clothing; Or through the interweaving of different yarns, forming a three-dimensional texture effect. These innovative textures and patterns add a sense of style and art to knitwear.
