      如何辨別背膠魔術貼質量?

      信息來源于:互聯網 發布于:2021-12-24

         1、背膠魔術貼光澤度:跟常規認識不同,當放在燈光或者有陽光的地方,傾斜看勾面魔術貼表面,滌綸魔術貼會有閃閃的反光點,而尼龍或者混紡就不會有!

           2、柔軟度:柔軟度會層層遞進,拿勾面魔術貼來試驗,會有更明顯的區別。建議拿4cm或者5cm寬的魔術貼來試驗為合適。其中的區別在于:滌綸背膠魔術貼硬的,混紡背膠魔術貼次之,尼龍背膠魔術貼為軟。
           3、須邊:有大量須邊的基本上就屬于滌綸的,混紡的偶爾有之,而尼龍粘扣帶基本上不存在須邊問題。
           4、抽絲:這個問題出現的情況同“須邊”。
           5、紋路:這個特點較容易分辨滌綸背膠魔術貼,因為滌綸背膠魔術貼多數情況因為廠家定位的原因,不會可以對待,所以會出現紋路會有彎曲,或出現拱形,或出現波浪形。而混紡和尼龍基本不會出現這個情況,這兩者較難分辨。

      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.
