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.
Claims15
A method of producing a yarn having a count between 6 and 100 Ne, comprising the steps,
- feeding fibers, from at least two bobbin lead rovings, to a roller system;
- joining said fibers, now yarn, upon delivery from said roller system;
- reverse twisting said yarn using a linear false twisting device, the yarn contact with a belt of the linear false twisting device at an angle between 15 to 45 degrees;
- passing said yarn through a first lappet;
- passing said yarn through a second lappet;
- and
- spinning said yarn upon a spindle,
- wherein the second lappet is 5 cm to 10 cm below the first lappet, and is configured to increase spinning speed of the spindle, and increase spin count of said yarn.
A non-chemically treated textile product having a count between 32 and 100 Ne, whereby said textile product contains a yarn produced by drafting said yarn through a false twisting device and a first lappet and second lappet while being wound on a spindle,
- wherein the yarn contact with a belt of the linear false twisting device at an angle between 15 to 45 degrees, and
- wherein the second lappet is 5 cm to 10 cm below the first lappet, and is configured to increase spinning speed of the spindle, and increase spin count of said yarn.
A ring spinning machine comprising 48 to 504 ring frames per side, each of said ring frames including the components:
- at least two bobbin lead rovings adapted to supply fibers;
- a roller system adapted to join the fibers and form yarn;
- a linear false twisting device adapted to reverse twisting said yarn, the yarn contact with a belt of the linear false twisting device at an angle between 15 to 45 degrees, the linear false twisting device is a continuous conveyor belt-type runner extending the entire length of the ring frames;
- a first lappet;
- a second lappet;
- a spindle system;
- and
- a motor for driving said linear false twisting device, a controller for said motor, and a belt drive positioned between said motor and said linear false twisting device,
- wherein the second lappet is 5 cm to 10 cm below the first lappet, and is configured to increase spinning speed of the spindle system, and increase spin count of said yarn.
