In the field of application technology of fluorine free waterproofing agents, in addition to conquering fabricsDrying, waterproof performance, tactile sensation, and hand scratch marksIn addition to common issues, with the further refinement of the terminal demand market, the application of fluorine free waterproofing agents in different product categories has also received increasing attention from industry practitioners.
The following text will discuss the use of fluorine free waterproofing agentsIn the category of shoe materials and fabricsIntroduce the progress of application technology.
In today's consumer market, with the improvement of consumers' quality of life and their deep pursuit of product experience, their performance requirements for various products are constantly increasing. In terms of footwear products, waterproof performance has improved from its previous levelOptional features have become one of the essential properties of shoe materials todayBehind this transformation are the various needs that consumers face in their daily life scenarios, whether it's traveling on rainy days, exploring outdoors, or engaging in daily work activitiesPrepare shoes with good waterproof performanceThey can all provide them with great convenience and comfort.
The types of shoe materials and fabrics are diverse and abundant, in order to meet the aesthetic, functional, and cost needs of different consumers. Among them, polyester mesh fabric is favored by many consumers for its good breathability and lightness, and is commonly used in categories such as sports shoes and casual shoes. This fabricThe mesh structure ensures air circulation while also improving waterproof performanceProposed higher challenges. Microfiber leather is a synthetic leather substitute that has a texture and appearance similar to natural leather, while also beingWear resistance and water resistanceExcellent performance in various aspects, widely used in high-end footwear products such as leather shoes and boots.
The core performance requirements of shoe materials and fabrics mainly focus onAnti siphon, rainproof, and stain resistantThese three aspects. The anti siphon performance is crucial because when shoes come into contact with moisture, if the siphon phenomenon is severe, the moisture will quickly penetrate into the shoes, causing the feet to become damp. This not only affects the comfort of wearing, but may also lead to foot diseases. The rainproof performance ensures that the shoes can effectively block the intrusion of rainwater and keep the feet dry in rainy environments. And anti fouling performance can make shoes easier to clean and maintain in daily use, extending the service life of shoes.
From the currently publicly reported technologies, it can be found that there are multiple ways to improve the performance of shoe materials.On the one hand,Good anti siphon properties can be achieved by controlling the contact angle between the shoe material and water droplets. The contact angle is an important indicator for measuring the wettability of liquids on solid surfaces. The larger the contact angle, the less likely the liquid is to spread on the solid surface, which means that the waterproof performance is better. The anti siphon fluorine free waterproof agent can adjust the contact angle between the surface of the shoe material and water droplets. The principle of this waterproofing agent is to change the surface chemical properties of the shoe material fabric, reducing its surface energy and increasing its contact angle with water droplets.
The test results on leather shoe material show that its static anti siphon climb within 24 hours is less than 10 millimeters, which means that the rise height of moisture inside the shoe material is very limited under long-term exposure to moisture. The dynamic anti siphon bending frequency is greater than 20000 times, indicating that even when the shoes are continuously bent, the waterproof agent can still maintain good anti siphon performance, fully reflecting the stability and reliability of the waterproof agent.
On the other hand, filling the pores of the microfiber leather base fabric fibersIt is also an effective method to improve the anti siphon properties of shoe materials and fabrics. The microfiber leather base fabric fibers have large pores, which provide channels for the rise of water molecules. The fluorine free small molecule chain structure in the fluorine free waterproofing agent can be used to fill these pores, close the upward channel of water molecules, and thus achieve the anti siphon effect of the microfiber leather base fabric. The advantage of this method is that it not only effectively improves the anti siphon performance, but also avoids the environmental problems that may arise from the use of fluorinated compounds. The fluorine free small molecule chain structure has good flexibility and stability, which can be firmly filled in the fiber pores without affecting the original properties and texture of the microfiber leather.
In conclusion,By controlling the contact angle and filling pores, the waterproof performance of shoe materials and fabrics can be significantly improved, meeting the growing performance demands of consumers for footwear products.
