In the range of polyolefins used for synthetic yarns the most common type is polypropylene (PP). The specific properties of this polymer is setting specific demands for the properties of the spin finish in spinning and down-stream processing. The compatibility of the polymer and the components used for the spin finish must be considered. Due to the hydrophobic character of the polymer a specifically designed wetting-system is required. This behaviour also causes difficulties in dyeing in the down-stream. Therefore, it is very common to spin already coloured yarns using a masterbatch including the dyestuff. Various colours and shades are available, which could provide individually influences on the processing properties to be considered in the design of the spin finish.
The main use of PP-yarns is the production of textile floor-coverings (carpet). Further uses are other interior-applications, coverings, belts and ropes. Very fine deniers are also used for apparel and functional textiles (sportswear).
PP is also widely used as staple-fiber for needling (nonwoven) and for spun-bond or melt-blown applications like diaper.
The suitable spin finishes for the different manufacturing technologies and uses are attached listed.
