Thin Boiling Starch :

During the process of weaving, the warp threads are subjected to friction and tension. The flight the crossing weft shuttle, the beating of the sley and the passing of the reeds cause friction. The drawing over of the cloth beam imposes tension, and the mechanical movements of the whole loom cause vibration all of which bear upon the wrap. Unless protected by some means, the thread would wear out and fray in weaving. This, in a nutshell, is the purpose of wrap sizing.

For better working in the loomshed, resistance to abrasion is of vital strengthening the warp yarn-by cementing the fibers with certain adhesive substances which can be applied easily and can also be removed with equal ease when the cloth goes for bleaching and subsequent processing. Much of the success of the sizing operation depends upon the choice of the most suitable sizing ingredients, which serve the above purposes.

Properties:
Thin boiling starch has low and uniform viscosity, which does not change much with temperature unlike native starches which show wide variation in viscosity. The keeping qualities of the native starch also show a marked variation, i.e. considerable degradation occurs on boiling.
Thin boiling starch non-congealing characteristic, transparency of paste and lower viscosity ensure easy working, compared to thick boiling starches. Unlike gum and glues which require soaking, Thin boiling starch is readily dispersed in water and can be boiled into a smooth paste without any pretreatment.
One of the main drawbacks of tapioca size is that it thins down very much on boiling, resulting in an uneven pick up on the high speed machine. The viscosity of thin boiling does not change with boiling and this ensures uniform pick up size even on modern high speed sizing machines.

Advantages :
1. Thin boiling starch, because of the low viscosity ensures uniform pick up and penetration. There is a very negligible variation in viscosity on boiling which result in uniform size than beam to beam on high speed modern sizing machines.

2. Thin boiling starch does not develop abrasive points on overdrying and its flexible film gives the yarn the desired elasticity.

3.Thin boiling starch size achieves a striking balance of surface coating and penetration, which ensures effective binding and reduces the droppings considerably in the loomshed.
4.
Thin boiling starch is compatible with all the ingredients used in sizing- humectant, lubricant, gums, synthetic sizes, etc.

5.Thin boiling starch is easily removed during the customary desizing process.

The above are decided advantages that make 'Thin Boiling Starch' an ideal sizing ingredient. Thin boiling starch is manufactured in different viscosities or fluidities, to suit the requirements of different types of warps. Depending upon the count and quality of the yarn, one can select a grade of Thin boiling starch that will not only give penetration but enough superficial coat to counteract the abrading action of healds and reeds at the loom stage.

Finishing:
In finishing, Thin boiling starch are prefer for a light finish when very little filling is required to give body to the cloth. For finishing dyes or printed fabric, a transparent size is required so as not to dull the colour on impair the design. In such application thin boiling starches are preferred to thick boiling starches.

The following table gives selected data on the useful parameters of Thin boiling starch to enable users to make a correct choice. It is necessary to use additive like gum or synthetic sizes when working with Thin boiling starch, about 6% to 7% pick up for low reed pick yarn about 10% to 13% pick up for a high reed pick yarn with requisite amount of softner will be just sufficient for good and uniform working in the loom shed.

Note: Our product, Thin boiling starch has been serving the sizing industry. In the process of weaving, friction and tension are caused to the warp threads.
Therefore protection in the process is necessary. And this is the reason for sizing the warp. The success of the sizing operation depends upon the choice of the most suitable sizing ingredients. Our products stands up to mark.
