In general, the present invention has to do with a UV reference indicator calibrated to represent the color or shade of a UV reactive dye after a predetermined exposure time to a UV radiation source.

A method for weaving pile fabrics with pile-free zones, in which, on a weaving loom, in successive series of at least two successive weft insertion cycles in each case at least one ground weft thread (1) and at least two effect weft threads (2),(3) having mutually different appearance-determining properties are inserted at well-defined weft-insertion levels, in which the effect weft threads (2),(3) in each series are inserted in successive weft insertion cycles, and in which, in order to create a predetermined effect in at least one pile-free zone, the warp threads (4-7); (12-22); (101-104) are positioned with respect to the weft insertion levels such that at least one effect weft thread (2),(3) runs on the pile side substantially uncovered.

Fibers, especially black, brown or gray fibers, comprising IR-transparent colorants. IR-transparent colorants may be di-, tri- or polychromatic dyes or pigments, especially perylene pigments. The fibers may comprise perylene pigments which comprise one of the isomers of the formula Ia or Ib ##STR00001##
in which the R.sup.1 and R.sup.2 radicals are each independently phenylene, naphthylene or pyridylene, each of which may be mono- or polysubstituted by C.sub.1-C.sub.12-alkyl, C.sub.1-C.sub.6-alkoxy, hydroxy and/or halogen, or a mixture of the two isomers. Useful fiber materials include plastics or glass. The fibers find use, among other uses, in heat management or for production of textiles or fabrics.

A method of forming color change fiber, comprises preparing polymer base material and preparing a plurality of warp yarns and a plurality of weft yarns , wherein the plurality of warp yarns are made by mixing a polymer base material with a color changeable material with a weight percentage ratio and the plurality of weft yarns are made of a polymer base material or natural fiber; forming a polymer fiber by spinning, weaving process for the warp yarns and the weft yarns, wherein the polymer fiber is color changeable when sunlight irradiates on the polymer fiber.

Laser finishing of apparel products allows an operating model that reduces finishing cost, lowers carrying costs, increases productivity, shortens time to market, be more reactive to trends, reduce product constraints, reduces lost sales and dilution, and more. Improved aspects include design, development, planning, merchandising, selling, making, and delivering. The model uses fabric templates, each of which can be used to produce a multitude of laser finishes. Operational efficiency is improved.

A fabric has enhanced response characteristics for laser finishing. The fabric can be denim for denim apparel such as jeans. Software and lasers are used to finish apparel made of the fabric to produce a desired wear or distressing pattern or other design. The fabric allows for relatively fast color change in response to the laser, color changes in hue from indigo blue to white, many grayscale levels, and maintains strength and stretch properties. A method used to make the fabric includes spinning, dyeing, and weaving yarns in such a way to obtain the desired enhanced response characteristics for laser finishing.

A housing of an electronic device according to various embodiments may include a woven material including TPU yarns, and a light emission module comprising light emitting circuitry, wherein light emitted from the light emission module may be directly transmitted through the woven material to display at least one piece of information about the electronic device.

Methods for processing denim are provided. An initial fabric is abraded by passing the initial fabric through an abrader at a first predetermined speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards, where each respective sanding board has a respective diamond surface that contacts the initial fabric while spinning about a respective axis at the respective center of the respective sanding board during the abrading. The pre-washed fabric is then washed with an ozone composition, thereby obtaining an ozone washed fabric.
