The uses of starch

Industrial applications

One of the earliest known industrial uses of starch was to ‘size’ and stiffen textiles. This is still true, but today starch does much more : it is added to individual yarns to increase mechanical strength and resistance to friction wear, and helps resist moisture penetration. And it can serve as a stabiliser and filler for coloured inks when fabrics are overprinted.
The detergent industry uses starch products for the production of biodegradable, non-toxic and skin friendly detergents. Starch products are also used in an array of less obvious applications : in fermentation – for the production of amino acids, organic acids, enzymes and yeast, by the chemical industry – for the production of surfactants, polyurethanes, resins, and in biodegradable plastics. But also in the construction industry – for concrete admixtures, plasters and insulation, as well as in oil drilling, mineral and metal processing.
