What should do if the fabric arch when it is bonding?

In the blink of an eye, it is already the end of October. Clothing professionals have just finished the production of the first half of the year's bulk orders, and soon immerse themselves in the intense planning and development of new styles.

However, Xiaobang received difficult position from customers.

First, let's take a look at what reasons could cause arching.

 
01

Poor recovery rate

The film with low recovery rate index, insufficient resilience. After being stretched by external force, the film itself cannot return to its original length together with the high elastic fabric, which may cause arching phenomenon.

02

Thermal sensitive fabric, when combined with regular high elasticity adhesive for lamination process, tends to shrink under certain high temperatures. This not only easily causes warping, but also affects the color and texture of the fabric.

Solve the problem of bonded arching

Spandex is the abbreviation for polyurethane fiber. It is an elastic fiber that has high elasticity. After being stretched several times its original length, it can quickly return to its initial state when the tension is released.

Applying it to the bonding technology and film combination can reduce the occurrence rate of arching during bonding.

HN-6893 high temperature and high elasticity spandex adhesive

Combining high elasticity and spandex, it maximizes the rebound of the fabric when bonding, meeting the elasticity requirements of clothing in areas under stress. The mesh structure facilitates the uniform penetration of the glue into the fabric, stabilizing the distribution of the colloidal particles in a grid-like pattern, avoiding irregular glue penetration, improving the strength of peel force, and reducing the arching rate.


 

HN-6893 low temperature high elastic spandex adhesive

High elastic spandex is combined with low temperature adhesive to meet the elastic requirements of different stress positions by choosing different gram weights. The elastic properties of spandex make up for the weak rebound of low temperature adhesive, while retaining the advantages of low temperature bonding operation, making it more friendly to heat-sensitive fabrics.
