Non-porous hydrophilic films used in the apparel industry

We all know the outdoor sporting goods required to achieve breathable, waterproof , comfortable effect , many businesses are constantly study how we can come up with better products , non-porous hydrophilic films appear to make outdoor sports apparel industry to get a new upgrade.
2013 Asia Outdoor Trade Fair will be held July in Nanjing International Expo Center , SympaTex? Cooperate together many customers at home and abroad again co-exhibitors and customers continue to demonstrate cooperation selling products and award-winning products , in order to show the true product allows you to learn more about SympaTex? .

Outdoor products mentioned functional , waterproof and breathable is the most basic and most important function of demand , while the waterproof breathable fabric has experienced compact fabric , waterproof and breathable fabrics after coating , the film has now developed into a paste -type fabric. Technical essence of each brand waterproof breathable fabric is concentrated on the functional thin film is used , such a functional film can be divided into : a microporous membrane , a dense hydrophilic membrane , combined with the hydrophilic porous membrane . Currently on the market for waterproof breathable membrane and fabric combination is mainly the first two , because the microporous membrane to enter the Chinese market earlier , we have a higher degree of familiarity . Dense hydrophilic film is the use of a dense solid film of hydrophilic polymer ( or a group containing hydrophilic side chains) is made , that is, the nonporous hydrophilic film is SympaTex? Company in 1980 developed a new waterproof breathable membrane .
From 1985 SympaTex? After the film used in the apparel industry , this high-tech material is truly a film for everyone to know, and gradually become well-known brands , as the market most common microporous membranes more powerful than its waterproof and breathable and environmental features , SympaTex? choice is becoming more outdoor brand new waterproof and breathable fabric .Sellotape

From the waterproof function , the microporous membrane pores smaller than water droplets , not smaller than water molecules , and microporous membrane waterproof function in the usual sense because the foundation is built on the existence of water on the surface tension of water molecular always gathered into droplets when the pressure is small, and the surface tension of the water can penetrate into the fabric of the equilibrium pressure , so that water does not leak. When the pressure increases to a certain extent , is insufficient to maintain the balance of surface tension , so it breaks into droplets smaller droplets , thus leakage occurs . So usually can withstand water pressure to the value of said fabric waterproof EPTFE class -based films . The SympaTex? Nonporous hydrophilic non-porous membrane because it can reach 100 % waterproof performance.
From the functional point of ventilation , compared to a microporous membrane , the nonporous hydrophilic film has a more powerful air permeability. SympaTex? Non-porous hydrophilic films by physical and chemical interactions to achieve ventilation , which stems from SympaTex? Operation of power is humidity and temperature differences between the body and the external environment that exists to promote water vapor molecules from the high humidity in the direction of low humidity where convection. Because water molecules and water vapor molecules containing one oxygen atom and two hydrogen atoms , when the water molecules in the gaseous state , very independent from each other , their freedom of movement like clouds , temperature, humidity, poor driving them in a way to wear a pass over the film goes out .Washi tape

SympaTex? Nonporous hydrophilic film of a hydrophilic polymer and the water repellent composition of the two substances , wherein the hydrophilic substance was inside the molecular chain structure , but with positive and negative charge on the molecular chain , a single water vapor can be adsorbed molecules of water vapor through the film 's accelerated pace , while also ensuring SympaTex? fabric products such as Jackets can be done better and , better ventilation effect . It is because of this special hydrophilic membrane structure, SympaTex? Nonporous membranes not only can guarantee good air permeability and permeability even higher than similar products.Masking tape

SympaTex? Fabrics in addition to the basic functions of the material (100 % waterproof , 100% wind, excellent ventilation ) , it can also be very environmentally friendly film , because 100% recyclable , and adopted the International Oeko-Tex Association Oeko-Tex Standard 100 bluesign certification and Switzerland ? certification, is truly environmentally friendly fabrics.
Outdoor sports apparel industry application of hydrophilic non-porous film material produced clothing , to breathable, waterproof , environmental protection , comfort , wind and a series of super performance , loved by the people .Wholesale masking tape
