Sileatehr丨当我们谈论皮革的时候 我们都在谈论什么

当我们谈论皮革的时候 我们都在谈论什么呢?

不管是Sileather, PU 还是 PVC,其测试的标准都是一致的,以下这些是来自美国的行业标准。

测量的属性

The properties measured include:

测量的属性包括:

Adhesion: How much force is required to separate the chemical coating from the base substrate? A universal tester, such as an Instron unit, is used to determine the force required to peel the coating from the fabric

附着力:测试将化学涂层与基布分离需要多大的力。通常使用通用测试仪,比如英斯特朗电子拉力机,测定从织物上剥离涂层所需的力。

Cold Crack: Is the fabric strong enough to resist cracking when bent or folded at low temperatures? A low temperature apparatus is used for this test.

冷裂:测试在低温弯曲或折叠时,织物是否足够坚固以抵抗开裂。该测试用的是低温设备。

Flex: When the fabric is flexed and twisted, does the fabric maintain its surface appearance or is there cracking, crazing or delamination? This test method employs a Flex-O-Test machine (formerly known as a Newark Flex Tester).

弯曲:当织物弯曲和扭曲时,织物是否保持其表面外观或是否有开裂,裂纹或分层。 该测试使用的是Flex-O-Test机器(以前称为纽瓦克弯曲试验机)。

Seam Strength: Does the fabric resist seam tearing? The sample is pressed onto a needle board and pulled on a universal tester for this test.

缝纫强度:织物是否能防止缝纫撕裂。通常将样品压在针板上,在通用测试仪上拉动进行该测试。

Tear Strength: How much force is required to tear the fabric? A universal tester is used to measure this property

撕裂强度:用于测试撕裂织物需要多大的力, 用通用测试仪测试。

Tensile Strength: How much force is required to break the fabric? A machine consisting of a straining mechanism, holding clamps and load recording mechanism can be used for this test. Tensile strength is also measured using a Universal Testing Machine

抗拉强度:用于测试破坏织物需要多大的力。由拉力器、固定器、负载记录组成的机器测试,也可以用万能试验机测量拉伸强度。

商业用途条件下的性能

To measure the film or coated fabric's ability to perform under the anticipated conditions of commercial use, test methods also assess the following properties.

为了测量薄膜或涂层织物在商业用途下的性能,还需评估以下性能。

Abrasion: How resistant is the coated fabric to damage when rubbed by an abradent such as a coarse woven fabric? The Wyzenbeek Abrader is used for this test.

耐磨:涂层织物在被粗糙织物等磨损物摩擦时有多大的抵抗力,该测试用威士伯耐磨试验机测试。

Blocking: Will the coated fabric become tacky at elevated temperatures and stick face to face when subjected to heat and pressure? A forced air laboratory oven is used for this test.

黏连性:涂层织物在高温下会变粘,在受热和受压时会面对面粘合吗。 该测试用的是强制通风实验室烤箱。

Crocking: Will color transfer from a coated fabric to another surface? A white cotton swatch, mounted on an AATCC-approved Crockmeter, is rubbed across the specimen and examined for any color transfer.

摩擦色:颜色是否会从涂层织物转移到另一个表面吗。 用AATCC认可的摩擦脱色评估仪上的白色棉布,在样品上摩擦,检查是否有颜色转移。

Exposure to Disinfectants: How does the fabric's surface, including color and gloss properties, perform after repeated exposure to cleaning agents?A method of disinfecting and examining fabric samples is used.

接触消毒剂:反复接触清洁剂后,织物表面(包括颜色和光泽度)会有什么变化,通常用使用消毒和检查织物样品的方法。

Light Stability: How resistant is a coated fabric to fading and degradation from sunlight (UV radiation)? A QUV unit or Weatherometer is used to assess this property. 

光照稳定性:测试涂层织物对光照(紫外线辐射)的褪色和降解有多大的抵抗力,通常用QUV单位或老化测试机测试。

Volatility: Will materials volatilize from a coated fabric at elevated tempertures? Samples are heated in the presence of activated carbon, which will absorb any volatile components. Percent weight loss is measured.

挥发性:测试材料在高温下是否会从涂层织物中挥发出来,在活性炭存在环境下加热样品,活性炭将吸收所有挥发性成分,测量重量损失百分比。
