Türk1. Advantages of four-sided stretch design
One of the core features of Circular Knit Interlining is its four-sided stretch, that is, the fabric has bidirectional elasticity in the horizontal and vertical directions. This elasticity not only enables the fabric to adapt to various body curves and movements, but also effectively improves the wearing comfort of the garment. Especially in sportswear, underwear, casual wear and other clothing that require flexibility, four-sided stretch can provide great freedom of movement.
However, the elasticity of the fabric is usually achieved by adding elastic fibers, the elasticity of these fibers is adjustable within a certain range. But the problem is that over-reliance on elastic fibers may cause the fabric to lose elasticity or deform after long-term use, which in turn affects the appearance and function of the garment.
In order to maintain durability, Circular Knit Interlining uses a combination of high-performance fibers such as polyester and spandex. The main advantage of polyester fiber is its excellent wear resistance and tensile resistance, which can effectively prevent the fabric from being damaged by repeated stretching. Spandex fiber is known for its high elasticity and resilience, and can quickly return to its original shape after a large stretch, reducing permanent deformation caused by elastic fatigue.
2. Circular weaving enhances fabric durability
Another key feature of Circular Knit Interlining is that it is woven using a circular weaving process. This weaving method makes the yarns of the fabric tighter, the fabric surface more uniform, and increases the tensile strength of the fabric. Compared with traditional flat or twill weaving processes, circular weaving can ensure the elasticity of the fabric while enhancing its overall structural stability and durability.
Circular weaving can also reduce the damage to the fabric surface caused by friction, stretching and other factors. Through this process, the Circular Knit Interlining fabric can still maintain good elasticity and smoothness during repeated wearing and washing, and is not prone to problems such as pilling, delamination or wrinkles.
3. Selection of high-performance fibers
The main raw materials used in Circular Knit Interlining are polyester fiber and spandex. The combination of these two fibers provides the fabric with excellent elasticity and durability.
Polyester fiber: As a synthetic fiber, polyester has excellent wear resistance, wrinkle resistance and stretch resistance. Polyester fiber has high strength and can withstand greater tension and wear. During the stretching process, it can maintain its original structural stability and avoid relaxation and deformation. These characteristics of polyester ensure that Circular Knit Interlining will not age due to frequent stretching during long-term use.
Spandex: Spandex is known for its excellent elasticity and can quickly recover after stretching. Its stretchability can usually reach more than 400%, which means that the fabric can maintain its elasticity even after long-term repeated stretching. This elasticity allows Circular Knit Interlining to provide flexibility and freedom in clothing design while maintaining high stretch resistance, making it less likely to lose its shape.
4. Durability testing and practical application
Circular Knit Interlining has undergone rigorous durability testing during the design and production process. It can withstand regular washing and wear and tear, and the fabric can still maintain its original elasticity and gloss even after frequent use. This high durability is particularly suitable for clothing that requires frequent washing and high-intensity use, such as sportswear, jackets, pants, etc.
In addition, clothing using this high-performance fabric generally shows a longer service life. Circular Knit Interlining has good anti-aging properties. Even under long-term sunlight exposure and washing conditions, the color and elasticity of the fabric can remain unchanged. It will not fade or relax due to external factors, extending the overall use cycle of the garment.
