Fluorine Free Waterproof Protective Agent Allows You To Travel Freely Between The City And The Outdoors

With the pace of modern urban life becoming faster and more stressful, more and more young people begin to explore outdoor activities that can be carried out in and around cities. Camping, fishing, cycling, mountaineering, hiking, Frisbee and other activities in cities attract more and more people to participate in them. Camping and hiking has become a "poem and distance" that people can reach. Set up a free camp in the open mountains with water, mountains and green, climb rocks in the rocky fields, play in the water in the valleys, draw inspiration from nature, awaken the vitality of DNA, and regain strength. However, it is not always easy for people to get close to nature. If they encounter bad weather, they will have to fight against the wet, cold and tough. At this time, a multi-functional anti water outdoor equipment is needed to deal with different scenes.

　　 Traceable water remover

　　 Today, the textile waterproof agent market has undergone earth shaking changes. Tracing back to the origin of the water repellent, as early as in ancient China, people dipped tung oil on cotton cloth to form a tangible protective layer and make oilcloth umbrellas. Later, people used paraffin/metal salts and other treatment agents to treat textiles to achieve the effect of water removal. However, the textiles treated by these methods are not ideal and durable. With the progress and development of technology, the fabric used for textile water treatment by organosilicon technology has soft hand feel and good air permeability. The disadvantage is that the peel strength of the fabric after film coating is poor, and the seam of the garment is easy to slip, so it is gradually replaced by organic fluorine water repellent. However, with the enhancement of people's awareness of environmental protection and the restrictions of relevant laws and regulations, organic fluorine water repellents are gradually replaced by non fluorine water repellents. In the current trend of sustainable development, fluoride free water repellents are more popular with domestic and foreign brands. ?

　　 3M Sigaojie Fluorine free Waterproof Scheme*

　　 At the moment of sustainable development, 3M takes the lead in introducing fluorine free waterproof technology for fabrics, and constantly optimizes products by integrating technology, so that consumers can truly feel the charm of environment-friendly materials and generate more interest. In the field of production, manufacturing and operation, 3M has vigorously promoted energy conservation and emission reduction, fully complying with the trend of sustainable development in the future. For the waterproof problem in life, 3M launched a new Sigaojie fluoride free waterproof scheme to help people improve their outdoor sports experience

　　 Sigaojie protective agent has global popularity and recognition: according to the survey of American consumers on Sigaojie brand recognition in 2020, 81% of consumers believe that Sigaojie is a trustworthy brand, and 79% of consumers believe that Sigaojie represents a high-quality water-resistant protection function.

　　 Note: * means that the formula does not add perfluoroalkyl or polyfluoroalkyl compounds (PFAS)

　　 Technical principle of 3M Sigaojie fluorine free waterproof agent

　　 The water pumping principle of 3M Sigaojie fluorine free waterproof agent mainly comes from the hydrophobic properties of such substances. The waterproof functional group we choose is the hydrocarbon long carbon chain with relatively low surface energy, which forms a uniform and dense invisible hydrophobic film under the action of the cross-linking group and the molecular support, which is coated on the surface of each fiber, so that it can play a lotus leaf like hydrophobic effect, making the fabric have a lotus leaf like self-cleaning characteristics, Make the water-based liquid roll down on the fiber automatically. At the same time, the gap between the fibers will not be blocked, and the permeability of the fabric itself will not be affected, so it is a "protective shield" for non personal clothing or textiles. ?

　　 Before using fluorine free water repellent, the fabric should be pretreated to fully remove the antistatic agent, oil and other impurities on the fabric. Because the antistatic agent is a hydrophilic material, it will reduce the water pumping effect of the fabric, and it is not washable at the same time; However, if the oil is not removed cleanly, the water absorption of the fabric will be poor, so that the liquid carrying rate of the fabric in the process of rapid padding working fluid is low, and it is difficult to achieve satisfactory water pumping effect. In addition, pre-treatment auxiliaries and leveling agents are hydrophilic substances, which will increase the surface tension of the fabric after drying and affect the water pumping effect. Therefore, the pretreatment auxiliaries and leveling agents on the fabric should be cleaned before finishing. ?

　　 In addition, other additives also have a certain impact on the fluoride free water pumping effect. For example, the main components of ordinary penetrants are hydrophilic substances, which cannot be volatilized during the fiber drying process and remain on the cloth surface, increasing the hydrophilicity of the cloth surface, thus reducing the water pumping effect. Adding a non rewetting penetrant, such as isopropanol, to the working fluid can improve the permeability of the cloth surface. At the same time, under the baking condition, the moisture will volatilize and will not remain on the cloth surface. When the amount is appropriate, the water pumping efficiency will not be reduced. The ordinary softener will affect the continuous hydrophobic layer formed by the fluorine free water repellent on the fabric, and the residue on the cloth will affect the hydrophobic property of the fabric, thus reducing the water repellent effect. Special softeners containing hydrophobic groups can be selected. The molecular weight of such softeners is appropriate, and the proper dosage will not significantly affect the continuous hydrophobic layer formed on the fabric by the fluorine free water repellent, so the water repellent effect will not be significantly reduced.

　　 3M fluorine free waterproof product

　　 This time, 3M Sigaojie launched two types of fluoride free waterproof products PM-3705 and PM2688. It is applicable to all kinds of fabrics and can be more effective waterproof. After 30 times of washing, the treated fabric still has high water splash resistance, while maintaining good air permeability and comfort ? And ZDHC certification, fluorine free environmental protection technology, waterproof and easier to clean, fully meet the needs of daily wear or outdoor sports, and at the same time, it has the characteristics of high performance and durability, giving fabrics high performance performance. For outdoor activities, it often uses outdoor products such as assault jackets, tents and sleeping bags, providing comprehensive design flexibility. ?

　　 In recent years, sustainable development has become the consensus of global enterprises and consumers, and is also the core goal of 3M's development. 3M has already integrated the concept of sustainable development into daily product development and operation. The 3M Sigaojie waterproof scheme can be said to fully meet people's functional demands for outdoor sports equipment, as well as the demand for outdoor activities to reduce environmental impact. In the future, 3M will continue to provide customers with high-quality products, application technologies and innovative solutions based on chemistry, and contribute to the sustainable development of the textile and clothing industry.
