Abstract
A spinning method and a spinning frame are provided that yields spun yarn, with the comfortable feel of a hand-spun yarn, on an industrial scale. In spinning frame 1, rovings 11 are drafted with signals derived from a numerical sequence of having a 1/f fluctuation or signals derived from a melody or other sound having a 1/f fluctuation to yield a spun yarn 13 in which the diameter varies with said 1/f fluctuation, thus providing a natural, comfortable feel.
Claims22
A spinning method that spins rovings into yarn comprising:
- drafting rovings into yarn with a specific standard thickness, said yarn varying in thickness within a limited range based on a 1/f fluctuation;
- and
- applying a twist to a fiber bundle drafted from said rovings.
A spinning method that spins rovings into yarn comprising:
- drafting rovings into a fiber bundle;
- and
- applying a twist by serial signals having a 1/f fluctuation to said fiber bundle.
A spinning frame that spins rovings into yarn, comprising:
- a back roller that draws rovings;
- an apron roller that draws a fiber bundle fed from said back roller;
- a front roller that draws a fiber bundle fed from said apron roller;
- a spindle that receives a fiber bundle fed from said front roller;
- and
- means for controlling drafting of a fiber bundle between said apron roller and said front roller in which a difference in drawing speed between said apron roller and said front roller has been set to vary with a 1/f fluctuation, and then applying a twist to the fiber bundle using said spindle.
A spinning frame that spins rovings into yarn, comprises:
- a back roller that draws said rovings;
- an apron roller that draws a fiber bundle fed from said back roller;
- a front roller that draws a fiber bundle fed from said apron roller;
- and
- a spindle that receives a fiber bundle fed from said front roller, wherein a rotational speed of said spindle, used to apply a twist to the fiber bundle, is set to vary with a 1/f fluctuation.
