Q. What are the different types of cotton threads?

Answer

Cotton may be spun into three separate sorts of threads:There is no more processing done to soft threads beyond bleaching, dying, and the application of a lubricant that is consistent and has a low coefficient of friction.When mercerized threads are treated in a solution of caustic soda, the fibres undergo a treatment that causes them to expand and become rounder in the cross-section. This treatment is performed under tension. This technique results in the fibres having a greater sheen as well as an improvement in their strength. This technique also has the effect of improving the dye's affinity.A polishing technique is used to soft cotton threads in order to make lace cotton threads. Glace cotton threads are made from soft cotton threads. In this technique, a coating of starch is applied to the surface of the thread, the fibre ends are brushed into the body of the thread, and they are allowed to dry, all of which contribute to the formation of a smooth surface on the thread.
