What is qualitative analysis and quantitative analysis for fibre?

Post 1 of 25

1) Qualitative analysis: To identify textile fibres for the accurate operation of product design, quality control and care instructions. Fibres may be examined in raw fibre form or taken from yarn or fabric.
2) Quantitative analysis: To determine the weight ratio and fibre composite in case a textile goods contains two or more different fibres.

Why do my products need to perform the tests for fibre identification?

Most countries importing apparel and soft home furnishing products require fibre identification labels that indicate the fibre type and percentage of fibre components. Some countries even use fibre composition to classify quota categories.

Perfluorooctane sulfonates-PFOS exists in salt, ramification and polymer in form of negative ion. It is oil and water proof, so widely used in the raw material of many consumer goods and industrial products including textiles, carpet, paper, photocopy paint, fire fighting foam, vedio material and aviation liquid oil, etc.

What is “Organic Cotton”? How does it differ from normal cotton?

Cotton is probably the most widely used textile fibre in the world and is grown in over 60 countries. Whilst perceived by the consumer as being a “natural” product, the fact that cotton production uses vast quantities of pesticides and fertilizes is frequently overlooked. These chemicals can have a massive impact on both the environment and on the health of the cotton growers.
There are various regulations covering what makes a product “organic”, but as a minimum, the definition of a cotton crop being organic is that it must have been “grown without pesticides, insecticides and defoliants on land that’s certified free from these synthetic chemicals for at least 3 years”.

Can you test to see if the cotton is organic or not?

It's not possible to test whether a product is made from organic cotton. Organic produce requires certification, and there are a number of organizations that offer certification of organic cotton, e.g. the OTA (Organic Trade Association) is the US; the Soil Association in the UK; KRAV in Sweden; SKAL in many European countries. These certification bodies are audited by organizations such as IFOAM (the International Federation of Organic Agricultural Movement).

Why vat dyes are better in light fastness?
Post 19 of 25

16 Jul 2008 11:20

In general, the larger the molecule / particle, the better will be the light fastness. Owing to their aggregation property, vat dyes molecules form large particles, which are more resistant to UV light.
