-
Q Do you have in-house testing facilities that support pre-treatment?
A In the raw form, the fibres whether they are natural or synthetic, consist of impurities that can affect the performance of the fabric. We manufacture organic textile auxiliaries for the pre-treatment process of the fabric. Yes, we have in-house testing facilities to ensure the pre-treatment process gets executed safely. With the help of modern technology and sustainable chemistry, we have built an effective testing hierarchy before recommending the products to our clients.
