如何识别尼龙织带真正身份 How to identify the true identity of nylon webbing

发布时间 Release time: 2023-11-29


  所需准备的工具:尼龙织带一条、涤纶织带一条(或者其它材质的织带)、打火机一个。

  步骤方法:将两种不知类别织带的经纬纱线拆出数根,分别用打火机燃烧织带,燃烧过程中观察一些物理现象,以确定经纬纱线的原料。燃烧时要分别对火焰、熔化情况及散发出的气味、燃烧后的灰烬的状况进行观察。

  下面是两种织带材料的燃烧物理性能参数,供大家参考:

  尼龙织带:靠近火焰即收缩熔融,滴落并起泡 不直接续燃,气味似芹菜味,燃烧冷却后出现硬、圆、轻、棕到灰色珠状。

  涤纶织带:靠近火焰即熔缩收缩熔融,滴落并起泡 能续燃,少数有烟,带有极弱的甜味。燃烧冷却后出现硬圆,黑或淡褐色的珠块。

  注意事项:不需要燃烧很久,点燃到鉴定材质一般30秒内就可完成。

Required tools: one nylon ribbon, one polyester ribbon (or other material ribbon), and one lighter.

Steps and methods: Remove several warp and weft yarns from two unknown types of woven tapes, burn the tapes with a lighter, and observe some physical phenomena during the burning process to determine the raw material of the warp and weft yarns. During combustion, it is necessary to observe the flame, melting situation, emitted odor, and the condition of the burned ash separately.

The following are the combustion physical performance parameters of two types of ribbon materials for your reference:

Nylon webbing: It shrinks and melts near the flame, drips and bubbles, and does not directly ignite. The odor is like celery, and after burning and cooling, it appears hard, round, light, brown to gray bead like.

Polyester webbing: It melts, shrinks, contracts, and melts close to the flame, drips and bubbles, and can continue to ignite. A few may have smoke, with an extremely weak sweetness. After combustion and cooling, hard round, black or light brown beads appear.

Attention: It does not need to be burned for a long time, and can be ignited to identify the material within 30 seconds.
