The present invention relates to a process for the production of a dyed biopolymer comprising the steps of providing at least one biopolymer-producing microorganism, providing at least one dye-producing microorganism, culturing said at least one biopolymer-producing microorganism to produce at least a biopolymer, and culturing said dye-producing microorganism wherein said dye-producing microorganism produce at least a dye suitable to dye at least part of said biopolymer, whereby a dyed biopolymer is obtained. The present invention also relates to a dyed biopolymer, to process for the production of a dyed composite article comprising at least the dyed biopolymer and to articles comprising the dyed biopolymer.

A method of manufacturing a plurality of colors of bulked continuous carpet filament from a single multi-screw extruder which, in various embodiments, comprises: (A) passing PET through an extruder that melts the PET and purifies the resulting PET polymer melt; (B) adding a liquid colorant to the polymer melt using a liquid metering system; (C) using one or more static mixers (e.g., up to forty static mixers) to substantially uniformly mix (e.g., homogeneously mix) the polymer melt and the liquid colorant; and (D) feed the uniformly mixed and colored polymer melt into a spinning machines that turns the polymer into filament for use in manufacturing carpet, rugs, and other products.

Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.

The present invention relates to a process wherein one or more dye precursors, e.g., indole, are provided to a textile and converted by one or more enzymes, e.g., an oxidizing enzyme, to provide the textile with a dye, e.g. indigo. At least the oxidizing enzyme is a hybrid enzyme including a binding domain that is suitable to bind the enzyme to the textile and/or increase the affinity of the enzyme for the textile, in particular, a cellulose binding domain (CBD).

A hollow fabric is obtained by providing cotton blended yarns and alkali-soluble polyester yarns which are arranged in a ratio of 10:2 as warp yarns, and providing cotton blended elastic yarns and alkali-soluble polyester filaments which are arranged in a ratio of 6:2 as weft yarns. The warp yarns and weft yarns are interwoven into plain weaves, and the plain weaves are subjected to alkali solution to remove the alkali-soluble polyester filaments, thereby obtaining greige cloth having meshes. The greige is subjected to boiled bleaching, softening and drying to obtain the hollow fabric. By optimizing the ratio of yarns and using a boiled bleaching, softening and drying process, a soft, smooth and fluffy product is produced with humidity-absorbing and breathability characteristics.

Provided is an enzymatic treatment on polyester/cellulose blend textile by contacting the textile with a cutinase and preferable with cellulose as well.

Provided is a reduction dyeing method for indigo using Dietzia sp. KDB1. The reduction dyeing method is relatively simple, efficient and allows good reproducibility, by using a Dietzia sp. KDB1 bacterial strain instead of a traditional fermentation process which entails poor reproducibility and is exacting and complicated. The method has the advantage of being able to substantially contribute to the field of dyeing using indigo, as the method can be used not only with natural indigo but also with synthetic indigo and makes it possible to efficiently increase the dye uptake of fabrics, and makes it possible to simplify difficult reducing processes including existing fermentation conditions which are exacting and complicated.

The present invention falls within the field of textile products, and specifically provides a brand new production method for a high-low pile towel. The method breaks through the visual monotony of conventional towels and a traditional design method in which two or three adjacent conventional pile loops have a consistent pile loop height in conventional high-low pile towels, but uses a design method in which two or three adjacent pile loops have a inconsistent pile loop height for weaving, and at the same time uses a special dyeing and finishing treatment, whereby the dyed and finished product has a special visual effect, a strong visual impact, and a fluffy and soft hand feel, and the product therefrom has a high additional value without improving the coats, compared with the existing products. The method fills up a blank of high-low pile towels, and can be widely popularized and applied.
