One of the most common uses of Maize Starch/Flour is in the textile industry. Maize Starch/Flour provides stiffness and adds weight to cloths. Starch/Flour is also used in conjunction with thermoplastic or thermosetting resins to obtain a permanent finish. In the textile industry, Starch/Flour is used in sizing to strengthen the warp yarn, in finishing and changing the appearance of fabric after it is bleached, dyed or printed, in printing and also to increase the consistency of printing pastes. Also Starch/Flour is used as a component in finishing agent to glaze and polish sizing thread.
There are many advantages of using Maize Starch/Flour in the textile industry such as the following:
- Maize Starch/Flour has low ash and protein content.
- Maize Starch/Flour does not thin down during the process of sizing (whereas tapioca Starch/Flour breaks down substantially on cooking, which results in an uneven pick up on the yarn).
- Maize Starch/Flour, unlike other Starch/Floures does not require steeping and long cooking time and is transformed into a smooth paste within an hour or in even lesser time under pressure-cooking.
- Maize Starch/Flour has uniform viscosity, from lot to lot, ensures uniform pick up and penetration into the interstices of yarn to ensure good weaving performance.
- Maize Starch/Flour does not foam and saves the requirement for antifoaming agents as it is pH is maintained in the neutral range (tapioca Starch/Flour has high pH which causes it to foam and requires antifoaming agents).
- Maize Starch/Flour is easily removed during the normal process of de-sizing.
