Buttonhole webbing products are widely used in life, and everyone is familiar with them in daily life, but it is not clear how to choose good quality buttonhole webbing. Buttonhole webbing manufacturers teach you to choose qualified elastic products, mainly looking at the following points.

1. Judging from the elasticity, whether the elasticity is sufficient or not, the tensile force of a good-quality buttonhole webbing should be between 1.8-2.8 times the original length. You can measure by hand feel and compare various buttonhole webbing. For accurate data, you can buy small instruments for measuring tensile force online.
2. Judging from the durability, the good buttonhole webbing is durable, and the poor quality buttonhole webbing loses its elasticity after a period of time. When choosing a buttonhole webbing, you should choose a stronger buttonhole webbing. A good-quality elastic band uses a lot of force to pull it, and a poor buttonhole webbing is easy to stretch.
3. Judging from the shrinkage, the shrinkage rate of high-quality buttonhole webbing is within 8% under high temperature or immersed in hot water.
