A tow band for heated tobacco product tip is a tow band of cellulose acetate provided by uniting and crimping a plurality of filaments into a bundle, in which a total denier is set to a value in a range of 10000 to 40000 (inclusive) and a filament denier is set to a value in a range of 6.0 to 20.0 (inclusive), and where the total denier is denoted by TD and a breaking strength of the tow band is denoted by F, a ratio F/TD is set to a value of 0.0015N/denier or more.

A composite interlaced yarn is a filament subjected to an interlacing process, wherein the filament is a multifilament, and the composite interlaced yarn includes a plurality of continuous circulation units in a longitudinal length; each circulation unit includes a splitting part I, an interlacing part I, a splitting part II and an interlacing part II connected in sequence; an interlacing fastness of the interlacing part I is different from an interlacing fastness of the interlacing part II. An interlacing method for the composite interlaced yarn includes: the multifilament that is not subjected to the interlacing process sequentially adjusting a pre-tension by a tensioner, passing through a yarn path of a jet, and winding by a winding roller, so as to obtain the composite interlaced yarn, wherein a jet hole I and a jet hole II are formed in the jet.

Articles of footwear may include a knitted component defining at least part of a void and joined with a sole structure. The knitted component may include an interior knit layer, an exterior knit layer, and a plurality of inlaid courses of a high tenacity yarn between the interior and exterior knit layers. The plurality of inlaid courses of high tenacity yarn may include at least three courses of the high tenacity yarn, each of which may be separated from an adjacent course of the plurality by no more than five courses.

Disclosed is an artificial turf fiber (204, 502-510, 804, 902-906, 1500, 1602-1618) comprising a longitudinal cross-sectional profile, the artificial turf fiber being under internal stress that causes the artificial turf fiber, upon receiving heat treatment, to assume a helical shape, wherein the core of the fiber consists of or predominantly comprises a core polymer, and wherein the periphery of the fiber consists of or predominantly comprises a cladding polymer, wherein the core polymer and the cladding polymer are different polymer materials, and wherein the core and cladding polymers are selected such that the core polymer undergoes greater shrinkage than the cladding polymer when subjected to the heat treatment.
