Enzymes (Desizing)
Within the textile industry, many different types of size are applied to various stages in the fabric preparation for various reasons such as lubrication and strength increases. Where wet processing is concerned, it is imperative that these sizes are removed for the benefit of further processing to run smoothly and to give as high quality fabric as possible at the end of the process.
The majority of cellulosic fabrics and its blends are typically impregnated with starch based sizes which are quite insoluble in water alone.
To remove these particular types of size, they must be treated by a suitable process using a suitable chemical or enzyme to break down the long chain molecule into its water soluble form. Some size treatments concentrate on scouring the fabric at the same time, usually known as an oxidative desize, where the use of oxidising agents such as hydrogen peroxide is involved.
Enzyme use is a much safer and easier route and is typically more efficient by way of reduced water and heat consumption. These particular enzymes that break the starch down are known as alpha amylases and vary in quality and strength.
Texchem utilise various enzymes for specific processing routes i.e. whether it is a hot or cold process and the time involved and liquor ratio.
