What should Interlining focus on in chemical test?

We keeps finding a sustainable solution which can help what we are wearing to be in a safe surrounding.

In the whole garment industry, the interlining ( or interfacing we called) occupies very small. But its safety to human-beings still matters.

Above in the picture is what we have done.

Basically, in fabric industry, these items should be tested and be shown to our customers:

  1. Azo Dyes
  2. Formaldehyde
  3. PH value
  4. Alkylphenol Ethoxylates (APEO)
  5. Hexavalent Chromium (CrVI) and Total Lead (Pb) – Heavy Metal

Azo Dyes

They are considered to be dangerous as there has been a relation found between these aromatic amines and cancers. Specifically, they have been seen to cause bladder and liver cancers. These Azo dyes can come into contact with human bodies through three different pathways: inhalation, ingestion and dermal absorption.

Formaldehyde

Formaldehyde can cause irritation of the skin, eyes, nose, and throat. High levels of exposure may cause some types of cancers. Learn more from the Agency for Toxic Substances and Disease Registry about the health effects of formaldehyde exposure.

PH value

CategorypH Value
Category A (textile products for infants and young children)4.0 to 7.5
Category B (textile products in direct contact with skin)4.0 to 8.5
Category C (textile products not in direct contact with skin)4.0 to 9.0

Alkylphenol Ethoxylates (APEO)

Concentrations of APEOs have been measured worldwide in surface waters, sediments and sewage. Slow to biodegrade, APEOs are toxic to aquatic organisms and an endocrine-disruptor to higher animals, and therefore pose a significant risk to humans.

Hexavalent Chromium (CrVI) and Total Lead (Pb)-Heavy Metal

Some reactive dyes contain metal complexes such as that of lead, copper, nickel, cobalt, and chromium. It is also possible for dyestuffs with metal-free chromophores to contain metallic impurities, originating from the raw materials used in manufacture.
