How do porous structures (such as mesh, honeycomb, etc.) ensure the stability of knitted fabrics while maintaining breathability?

The application of porous structures (such as mesh, honeycomb, etc.) in knitted fabrics can indeed greatly improve the breathability of fabrics while maintaining their stability, which is mainly due to the following design and considerations:
Fiber selection and blending: First, select fibers with excellent physical properties as the base material, such as chemical fibers such as polyester and nylon, which have good wear resistance and wrinkle resistance. At the same time, by blending with natural fibers (such as cotton and bamboo fibers), the advantages of both can be combined to improve breathability and moisture absorption, and enhance the stability and durability of the fabric.
Structural design optimization: When designing a porous structure, the size, shape and arrangement of the coils need to be carefully planned to ensure that while forming a breathable channel, the coils can support each other and form a stable structure. For example, the honeycomb structure not only improves breathability, but also enhances the overall stability and strength of the fabric by imitating the hexagonal arrangement of honeycombs in nature.
Reinforcement treatment: For some parts that need to be particularly stable, reinforcement treatment can be used, such as adding additional coils or weaving in reinforcing fibers at key stress points to improve the fabric's tensile and tear resistance.
Finishing process: Through appropriate finishing processes, such as heat setting and resin finishing, the fabric structure can be further stabilized to reduce deformation caused by external forces during use. These processes can adjust the arrangement and bonding of fibers to make the fabric smoother and crisper while maintaining good air permeability.
The application of porous structures in knitted fabrics requires comprehensive consideration and optimization in terms of fiber selection, structural design, reinforcement treatment, and finishing processes to ensure that the fabric is stable and durable while maintaining air permeability.

How does the proportion of different fibers during the blending or interweaving process affect the breathability and moisture absorption of knitted fabrics?

During the blending or interweaving process, the proportions of different fibers have a significant impact on the breathability and moisture absorption of knitted fabrics. This impact is mainly reflected in the following aspects:
Combination of fiber properties:
Blended fabrics balance breathability and moisture absorption by combining the properties of different fibers. For example, natural fibers (such as cotton, wool) usually have better hygroscopicity, while synthetic fibers (such as polyester, nylon) have better wear resistance and certain breathability. By adjusting the ratio between the two, the moisture absorption of the fabric can be improved or maintained while maintaining a certain breathability.
Changes in breathability:
Changes in fiber proportion will directly affect the breathability of the fabric. Generally speaking, blended fabrics containing more natural fibers (such as cotton) have relatively better breathability because natural fibers are more hygroscopic and breathable than synthetic fibers. However, if the proportion of synthetic fibers (such as polyester) is too high, the breathability of the fabric may be reduced due to the tight arrangement of fibers and lower moisture absorption.
Hygroscopicity adjustment:
Changes in hygroscopicity are also affected by fiber proportions. Natural fibers (such as cotton, bamboo fiber) have better hygroscopicity, while synthetic fibers (such as polyester, polypropylene) have poor hygroscopicity. By adjusting the proportion of natural fibers and synthetic fibers in blended fabrics, the moisture absorption of the fabric can be adjusted. For example, increasing the proportion of natural fibers can increase the moisture absorption of a fabric, while increasing the proportion of synthetic fibers may reduce its moisture absorption.
Balance of overall performance:
In actual production, in order to balance the breathability and moisture absorption of the fabric, the proportions of different fibers are usually determined based on the specific needs and usage scenarios of the product. For example, for knitted fabrics worn in summer, the proportion of natural fibers may be increased to improve breathability and moisture absorption; while for products requiring higher wear resistance and wrinkle resistance (such as sportswear), the proportion of synthetic fibers may be increased. Proportion.
The proportion of different fibers in the blending or interweaving process has an important impact on the breathability and moisture absorption of knitted fabrics. By scientifically and rationally adjusting the fiber ratio, fabric performance can be optimized to meet the needs and usage scenarios of different consumers.
