发明名称 Effect yarn mfg.
摘要 For continuous mfg. of a thermally fixed effect yarn, the separate yarns (A,B,C) comprise at least one core yarn (A) and the two effect yarns (B,C) and they are fed (1,2,2') pref. under electronic control, through a random program so that they are laid and overlaid along the core at different speeds to give the colour effects. A connection (3) can give alternating designs and fancy effects between the yarns. A bobbin (4) is carried by a central spindle (5), with a central drilling as a passage for the core yarn (A) or the effect yarns (B,C), while the bonding yarn (6) is drawn off the bobbin (4). The false twister (7) is at the outlet of the spindle (5) to give a false twist between the core yarn (A) and the effect yarns (B,C) together with the bonding yarn (6), and prevents any loosening of the false twisting effect downstream of the false twister (7). A further feed (8) is at the outlet of the false twister (7). The effect yarn is thermally fixed in a heater (9), and downstream of the heater (9) the feed operates at a speed according to the emerging speed of the yarn from the false twister (7) to control the yarn speed as it passes through the heater (9). The appts. also has a lubricator (11) and a winding bobbin (12) for the finished yarn.
