Hot melt adhesive film mesh will present many different performance requirements due to different materials, such as high temperature resistance and washing resistance. I believe everyone knows more about the high temperature resistance, and many people may not be familiar with the washing resistance. Washing resistance is also one of the important properties of hot melt adhesive omentum. Especially for the clothing industry, the water washing resistance of hot melt adhesive omentum is very important.
It is related to the use of hot melt adhesive omentum for seamless bonding. Is the clothing durable? Many people may not know what the water resistance refers to. In layman's terms, it means that the fabric can maintain a relatively high level after being bonded by the hot melt adhesive membrane, soaked in a certain temperature of water and repeatedly rubbed. Bond strength performance.The hot melt adhesive reticular membranes with comparison of water washing resistance mainly include pes hot melt adhesive reticular membrane, pa hot melt adhesive reticular membrane and tpu hot melt adhesive reticular membrane.
Since the high requirements for washing resistance are usually in the field of clothing, there are also certain requirements for the softness of the hot melt adhesive mesh, so pa hot melt adhesive mesh and tpu hot melt adhesive mesh will be used a little more.Some people may say that eva hot melt adhesive membrane also has certain washing resistance, but the washing resistance of eva hot melt adhesive membrane is far worse than pa and tpu hot melt adhesive membrane. Therefore, eva hot melt adhesive mesh is generally not recommended in the field of clothing. Strictly speaking, the washing resistance can also be divided into different grades, such as washing at room temperature, washing at 60 degrees, and washing at 90 degrees.
The higher the temperature, the higher the requirement for the washing resistance of the hot melt adhesive film. Let’s take the pa hot melt adhesive omentum as an example. The non-functional pa hot melt adhesive omentum can withstand room temperature water. It is OK even if it is washed in warm water around 60 degrees, but it is not suitable if it is washed in 90 degrees hot water. . At this time, functional pa hot melt adhesive omentum is generally used.The characteristics of the functional pa hot melt adhesive omentum are a little different from the conventional pa hot melt adhesive omentum, for example, it can be flame-retardant and can withstand boiling at 100 degrees.
