Polyester POY
POY / PFY is largely used in shirtings and suitings, sarees, ladies’ dress material, and knitwear. It is preferred in men’s wear due to its higher crease recovery, wrinkle resistance, better drape, longer retention of prints and colours, and better abrasion as compared with competing fibres, such as PSF, VSF and NFY.
The use of POY / PFY in sarees has increased due to the development of crimping, twisting, texturising and wet processing technologies. These technologies offer more flexibility in designs and patterns. Moreover, these technologies help increase the air permeability of these yarns. As a result, the fabric would be able to absorb more moisture.
It is also used in applications, such as soft luggage and specialty fabrics. POY is sold by producers to the texturising units. The texturising units process it and sell it to weavers (largely in the powerloom sector). Unlike PSF, PFY is not blended with cotton by blended yarn producers, since it is in the filament form and not in the fiber form. However, in the powerloom stage, PFY can be woven with other yarns.
POY / PFY is a substitute for cotton and other synthetic yarns. POY / PFY has a number of advantages over its substitutes.
These advantages include:
Better Properties: POY / PFY is more durable, does not fade on exposure to sunlight or soap, has better abrasion resistance, drape and crease recovery properties, and is wrinkle resistant
Price Competitiveness: Since the 1990s, POY prices have declined significantly, largely due to the decline in the landed costs, on account of decline in the import duty
FULLY DRAWN YARNS
Normal Partially Oriented Yarn (POY) needs to be necessarily texturised before being used for making fabric whereas FDY, as the name of the yarn itself indicates, is drawn fully during the process of spinning itself and therefore does away with the requirement of texturising and can use directly for making fabric.
FDY is generally used for better quality fabric. As the process of texturising is avoided, FDY yields higher contribution as compared to the normal POY.
The following are the properties incorporated during texturing of FDY:
Low Intermingle Yarn
These are comprised of high modules mono filaments. The range is highly popular because the entanglement spacings in these yarns are relatively low and the tenacity remains relatively unaffected.
Non Internmingle Yarn
Non Intermingle Yarn is known for their minimal entanglement spacings and hence it facilitates easy use.
High Intermingle Yarn
These yarns are commonly used for making fabrics. The range can be availed in different Deniers depending upon the requirements of the clients.
