如何辨别背胶魔术贴质量?

信息来源于:互联网 发布于:2021-12-24

   1、背胶魔术贴光泽度:跟常规认识不同,当放在灯光或者有阳光的地方,倾斜看勾面魔术贴表面,涤纶魔术贴会有闪闪的反光点,而尼龙或者混纺就不会有!

     2、柔软度:柔软度会层层递进,拿勾面魔术贴来试验,会有更明显的区别。建议拿4cm或者5cm宽的魔术贴来试验为合适。其中的区别在于:涤纶背胶魔术贴硬的,混纺背胶魔术贴次之,尼龙背胶魔术贴为软。
     3、须边:有大量须边的基本上就属于涤纶的,混纺的偶尔有之,而尼龙粘扣带基本上不存在须边问题。
     4、抽丝:这个问题出现的情况同“须边”。
     5、纹路:这个特点较容易分辨涤纶背胶魔术贴,因为涤纶背胶魔术贴多数情况因为厂家定位的原因,不会可以对待,所以会出现纹路会有弯曲,或出现拱形,或出现波浪形。而混纺和尼龙基本不会出现这个情况,这两者较难分辨。

1. Glossiness of the adhesive Velcro: Different from the conventional understanding, when placed in a light or sunny place, look at the surface of the hook surface at an angle. Polyester Velcro will have shiny reflective points, while nylon or blended fabrics will not. Have!

     2. Softness: The softness will increase layer by layer. Test with hook surface Velcro, there will be a more obvious difference. It is recommended to use a 4cm or 5cm wide Velcro to test it as appropriate. The difference is: polyester adhesive Velcro is hard, blended adhesive Velcro is second, and nylon adhesive Velcro is soft.
     3. Fraying: the ones with a large number of fraying are basically polyester, and the blended fabrics occasionally have them, and the Velcro tape basically has no fraying problem.
     4. Snagging: The situation of this problem is the same as that of "sharing".
     5. Grain: This feature makes it easier to distinguish polyester adhesive Velcro, because polyester adhesive Velcro can not be treated in most cases because of the manufacturer’s positioning, so there will be curves, or arches, or waves. shape. This is basically not the case for blended and nylon, and it is difficult to distinguish between the two.
