Abstract
The present invention relates to a machine, a system, and textiles resulting from an industrially produced yarn, created through the incorporation of a linear false twisting device and two lappets positioned to affect a yarn during drafting. The invention results in a yarn having a low twist multiplier. The textiles products created from the produced yarn exhibit a soft feel without requiring the use of chemical treatments.
