Draw textured yarn (DTY) is made from Partially Oriented Yarn (POY).Intermingled DTY yarn is a technology which is very economical than the older technologies like sizing, twisting in synthetic yarn weaving. In this technology air causes the filaments to be intertwined and mingled with each other to form a compact section.
They are categorised as :
-NIM (non-intermingled):0-10 knots per meter ; NIM means having no knots
-SIM (slight-intermingled): 40-50 knots per meter ; SIM is that the network fastness is very low and it is pulled scattered with hand dragging polyester yarn.
-HIM (high-intermingled) :100-120 knots per meter ; HIM means to pull the polyester yarn very hard by hand, and it is difficult to spread the pull.
