Reason analysis and treatment plan of insufficient stripping strength of interlining

When the interlining is bonded to the fabric, if the bonding strength is not high, the peel strength is not high. The reasons for insufficient peel strength are mainly as follows:

1. The temperature of the interlining does not meet the requirements when bonding, and the hot melt adhesive powder is not fully melted;

2. The temperature during bonding exceeds the optimal bonding temperature, which means that the hot-melt coating of the interlining is excessively melted and lost;

3. The coating on the interlining is uneven or the amount is not enough;

4. The pressure used by the bonding machine is not enough when bonding the interlining;

5. The humidity is too high.

Faced with the above reasons, we can do the following solutions:

1. Carefully read the best bonding conditions for the interlining provided by the interlining manufacturer, and adjust the best bonding conditions (temperature, time, pressure) according to the characteristics of the fabric;

2. Select high-quality interlining cloth, good interlining cloth weight standard, uniform coating;

3. Use a good bonding machine, usually pay attention to maintenance, and replace the aging parts;

4. Try not to use linings that have been stored for too long, and avoid moisture and direct sunlight for storage linings.
