The invention relates to the technical field of textile printing and dyeing, in particular to a method for preparing yarn with cloud dyeing effect; dyes with more than one color are mixed, and a small amount of dispersing agent is added, so that the pigment is not completely uniformly mixed, and the yarn obtained by extrusion molding of the pigment mixed spinning raw material has a randomly distributed multi-color cloud dyeing effect, and the cloud dyeing yarn with multi-color cloud dyeing effect is prepared, and compared with the cloth blank prepared by the traditional single-color yarn, the prepared cloth blank has a more three-dimensional pattern effect.

An article of manufacture, comprising, an artifact formed from at least a portion of at least one continuous artifact fiber, the artifact fiber dyed by a first digitally controlled dyeing process to exhibit a visible first color section and a visible color gradient section transitioning from and visibly distinguishable from the first color section; and, a textile portion, comprising at least one dyed fiber that has been dyed by a second digitally controlled dyeing process; wherein said artifact fiber is dyed by the first dyeing process applying metadata, said metadata relating to at least said first color, and wherein said textile portion fiber is dyed at least said first color by the second dyeing process applying said metadata.

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.

A color-changing product includes a fabric and a color-changing fiber embroidered into a portion of the fabric. The color-changing fiber includes an electrically conductive core and a coating disposed around the electrically conductive core. The coating includes a thermochromic pigment.

A linear textile structure has at least two strands, wherein a first strand has microfibers and a second strand encloses the first strand, wherein the structure may provide a stable linear textile structure, by which the most effective cleaning possible can be achieved with minimum effort. Both strands can be brought into contact together at least in some sections and simultaneously with a surface to be cleaned.

An authentication device comprising a woven authentication pattern, wherein the woven authentication pattern comprises a plurality of pattern forming woven elements each defining at least one pattern defining element or a plurality of pattern defining elements, and each pattern forming woven element is formed by a plurality of threads having contrasting optical or visual properties in twisted mutual engagement, wherein said pattern defining element has a spiralling outline or boundary and adjacent or abutting pattern defining elements of a pattern forming woven element are visually or optically distinguishable.

This weaving machine (2) is for simultaneously weaving a top pile fabric (F2) and a bottom pile fabric (F4), each pile fabric presenting some pile patterns (P2, P2, P4) and including tufts, made from warp yarns (24), binding warp yarns (14, 16) and inwoven weft yarns. This machine comprises a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) for creating a shed with the pile warp yarns and the binding warp yarns (14, 16). A weft insertion unit (8) is used for inserting the weft yarns in the shed in successive insertion cycles. A beating-up mechanism (32) is used for beating the weft yarns into the shed. A take up system (70) is used for taking-up the two pile fabrics. A drawing-in unit (26) draws the pile warp yarns from the pile warp yarn unit (20) and a control unit (80) controls operation of the weaving machine (2). This weaving machine also comprises a treatment unit (90) located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (26) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).

The present invention provides a colored gold-wrapped thread and a method for making a gold-plated embroidery by using the same, thereby solving the technical problem of single color of a gold-plated embroidery. The method for making a gold-plated embroidery includes preparing embroidery threads, preparing colored gold-wrapped threads and colored gold fixing threads in a mode of one-to-one correspondence of the same color, preparing an embroidery backing material, arranging a to-be-embroidered pattern on the embroidery backing material, preparing embroidery tools, arranging the embroidery backing material on a reel, and embroidering a pattern. The colored gold-wrapped thread includes a thread skin and a wrapped core, where the thread skin is made of a colored glittering silk material having metal luster, and the wrapped core is made of rayon having no twisting strength or a soft and smooth cotton thread.

An alternating color fabric includes a base portion woven by first yarns, a pleat portion woven by second yarns, and a hydrophilic resin layer formed on the pleat portion. A water contact angle of the hydrophilic resin layer is not more than 60 degrees. The base portion presents a primary color, and the pleat portion presents a secondary color, and the primary color is different from the secondary color.

A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.
