A knitting yarn used for forming a knitted product without using any knitting tools, such as crochet hooks or knitting needles. The knitting yarn includes a core thread having a length dimension and a plurality of loops affixed to the core thread, at least a first thread and at least a second thread having different structural and/or physical properties than each other; and the loops of the knitting yarn are made of the first thread, and the core thread is made of the second thread.

Provided is a strand extending in the longitudinal direction, wherein the strand includes filaments of one type having a gradient-length effect through spiral rotational twists and an irregular fine texture through self-thermal shrinking. The filaments of the strand have natural coiling characteristics that are very similar to those of natural hair of black people, and these characteristics are caused by the facts that the filaments have 3-dimensional waveforms occurred due to many fine and irregular windings or projections and that the waveforms exhibit fractal structure features and a fine kinky texture.

A recycled fancy yarn includes at least two core strands forming a warp thread, and at least one ornamental strand that is twined, twisted or wound around the warp thread to form a weft thread. The core strand is formed by a single first monofilament or a single first filament bundle, and the ornamental strand is formed by a single second monofilament or a single second filament bundle. The first monofilament and/or second monofilament is made of an environmentally friendly material; or the recycled fancy yarn can be recycled or naturally decomposed in the environment, such that the quantity of produced wastes can be reduced, and environmental burden is hardly caused.

A knitting yarn for manually forming a knitted product without tools includes a thread having a length dimension extending along an axis (A); a plurality of loops affixed to or formed with the thread by extending outwardly of the thread; and each of the plurality of loops defining an interior space adapted to receive another loop of the plurality of loops. The plurality of loops includes a first loop set mainly extending outwardly along +y axis and a second loop set extending along y axis; and, the first loop set is essentially symmetrical to the second loop set around the symmetry axis (A). A method of manually forming a knitted product by using the knitting yarn; and the knitted product obtained thereof.

An object of the present invention is to provide a bulky yarn made of synthetic fibers, which is suppressed in tanglement between filaments while having a loop shape in the surface layer thereof, and has a soft texture and is light and excellent in heat retention properties while being good in handleability in high-order processing. The present invention provides a bulky yarn made of synthetic fibers, including: a sheath yarn having a three-dimensional crimped structure; and a core yarn twisted with the sheath yarn to fix the sheath yarn, wherein the sheath yarn is not substantially broken and continuously forms loops.

A yarn includes a continuous strand formed with equally spaced equally dimensioned loops for knitting a multi-colored design in a knitted work formed of p courses or rows and q wales by sequentially pulling one loop in one row through a previously applied loop in an adjacent loop. The continuous strand is sequentially colored along its length with colors C.sub.i, C.sub.2 . . . C.sub.n to correspond to the colors of the stitches of the design over said p courses and q wales. A method of producing a single strand of yarn formed with equally spaced equally dimensioned loops, segments or section includes creating a grid of p courses or rows and q columns or wales; mapping a non-random distinct design on the grid to be formed by stitches of one of n colors; translating the grid to color sequences in each row corresponding to the color stitches in successive rows in the grid; and coloring loops, segments or sections of the strand of loopy yarn with the color sequence represented by the successive rows of the grid.
