    Abstract: The present invention provides a sculptured pile fabric having both a printed pattern and a sculpted surface of various pile, heights. The fabric of the present invention has improved aesthetic qualities as compared with sculptured products of the prior art. This improved sculptured fabric is the result of a chemical sculpting method, in which the height of the pile surface is selectively reduced in a pattern configuration, and that is followed by an overall “dilute” dyeing process. This “dilute” dyeing process is similar to that used to “tea stain” textile products, wherein an overall hue is imparted to a textile by the use of a relatively dilute (low concentration) dyestuff. The resulting sculptured product has an appearance that emphasizes the sculptured areas, making the sculptured areas appear to have greater depth, especially when viewed at a distance.

The process includes selecting a synthetic or synthetic blended fabric for the dyeing process by determining the fabric's shrinkage in the warp and fill directions, for instance no greater than 6%, constructing a garment from the fabric selected, then dyeing the constructed garment in an aqueous dyebath at a temperature in the range of 220 to 260° F. for a time sufficient to achieve a desired shade and levelness of color followed by drying and optionally pressing the dyed garment.

  • Patent number: 6302922
    Abstract: There is provided a process for manufacturing woven or knitted fabrics comprising modifying the woven or knitted fabrics by applying a skeleton triazine cross-linking reaction using a sericin fixing method of raw silk to enhance its shrink and crease resistance and shape stability and thereafter removing the sericin using a special scouring. The process for manufacturing a woven or knitted fabric, comprises the steps of finishing and treating raw silk and/or cellulose fibers by using a silk sericin fixing method; doubling and twisting thus finished/treated raw silk and/or cellulose fibers; weaving or knitting the doubled and twisted yarns; swelling the woven or knitted fabric forming a cloth by dipping it in a bath; and, scouring the woven or knitted fabric swelled in the bath with an enzyme whereby the woven or knitted fabric is provided with shrink and crease resistance and shape stability.

  • Patent number: 6200355
    Abstract: Methods for the deep shade dyeing of melamine fiber-containing textile articles include bringing an undyed melamine fiber-containing textile article into contact with a dye bath containing a dyestuff and an acid donor at a pH of greater than about 6.0 and an elevated dyeing temperature greater than about 100° C. for a time sufficient to dye the textile article with minimal loss of melamine fibers due to acid hydrolysis. Most preferably, the textile article or articles to be dyed is placed into the dye bath at ambient temperature, and thereafter the dye bath containing the textile article or articles to be dyed is heated to the elevated dyeing temperature, for example, at a rate of between about 0.5 to about 2.0° C. per minute. Suitable dyes include non-complexed acid dyes or acid dyes complexed with a metal (e.g., iron, cobalt, copper, aluminum or any transition metal). Suitable acid donors include butyrolactones, ethylene glycol monoformates and ethylene glycol diformates.

  • Patent number: 6159249
    Abstract: In the dyeing of hydrophobic fibers comprising new synthetic fibers, especially those called micronfine fibers, etc., it is difficult to obtain a dyed product having excellent fastness and it is further difficult to obtained a dyed product excellent also in color rendering. The present invention solved the problem as following:A specific dye composition containing a water-insoluble monoazo disperse dye represented by a specific structural formula is used to dye hydrophobic fibers, especially polyester fibers, comprising micronfine fibers, thereby giving a dyed products excellent in fastness balance and color rendering.

  • Patent number: 6086638
    Abstract: The method for dyeing a polyamide fabric of the present invention comprises the step of dyeing a polyamide fabric having structural variations in the longitudinal direction of the fibers, by a dye liquor containing an anionic reactive dye and regulated at pH 3.about.8. The dyed product of the present invention is a dyed polyamide fabric obtained by said dyeing method. Furthermore, the dyed product of the present invention is obtained as a grandrelle tone dyed product by dyeing a polyamide fabric having structural variations in the longitudinal direction of the fibers by a reactive dye, and being 4th or higher grade in the wash fastness specified in JIS L-0844.The present invention can provide a method for dyeing a polyamide fabric in a clear high grade grandrelle tone and to have excellent wash fastness, and also a grandrelle tone dyed product.

  • Patent number: 6068666
    Abstract: Textiles are first manufactured to attain dimensional stability and durability and thereby withstand the rigors of industrial rental and commercial laundering. Then, the garments are dyed in a two-stage process to yield outstanding colorfastness, pilling resistance, dimensional stability and durability. Garments are yielded that, even after extensive use, may be overdyed to custom colors in custom-sized batches to extend the useful life of stained or otherwise discolored garments. By performing the dyeing and/or overdyeing portions of the process at a location near the end user of the textile, transaction costs related to transportation of goods are minimized, technical resources are efficiently utilized, and large inventories of dyed garments need not be maintained, thereby reducing inventory expenses.
