The present invention relates to a process for producing dyed mixed fibres (D-MF), dyed mixed fibre yarns (D-MY) and/or dyed mixed fibre textile fabrics (D-MT) in which mixed fibres (MF), mixed fibre yarns (MY) and/or mixed fibre textile fabrics (MT) comprising at least one polyester fibre (PF) and at least one further fibre (FF) are simultaneously contacted with at least two different dyes (D1) and (D2) at a temperature T.sub.D<130° C. The at least one polyester fibre (PF) comprises 80 to 99.5% by weight of at least one terephthalate polyester (A), 0.5 to 20% by weight of at least one aliphatic-aromatic polyester (B) and 0 to 5% by weight of at least one additive (C), wherein the % by weight are based in each case on the total weight of components (A), (B) and optionally (C). Moreover, the present invention relates to the dyed mixed fibres (D-MF), the dyed mixed fibre yarns (D-MY) and/or the dyed mixed fibre textile fabrics (D-MT) obtained by this process.

The present invention relates to the use of indigo derivatives for dyeing synthetic textiles to a process for dyeing synthetic textiles and to dyed textiles and articles containing them. The invention also relates to novel indigo derivatives per se and to a process for the preparation thereof.

An object of the present invention is to provide a dyed fabric and a textile product made thereof, as well as a dyeing method, which achieve color uniformity of a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber, even in the case of a fabric containing a meta-type- and para-type-wholly aromatic polyamide fibers and a polyester fiber which are difficult to dye. The present invention relates to a dyed fabric dyed after being shaped into a fabric, characterized in that the fabric includes a meta-type wholly aromatic polyamide fiber, a para-type wholly aromatic polyamide fiber and a polyester fiber and the fabric is a fabric dyed with a cationic dyestuff and a disperse dyestuff, and in that the afterflame time and afterglow time defined in JISL1091A-1 are 1 second or less.

A method of infusing CBD oil into polyester yarns or polymer fibrous structures to establish reservoirs of CBD in said yarns or structures of sufficient integrity to withstand multiple washing cycles while periodically allowing migration of CBD from said reservoirs to the skin of a wearer of a product made from the infused yarns or polymer fibrous structures

A method for dyeing, such as vat dyeing, or coating synthetic fibers, such as polyester fibers and/or polyamide fibers, or yarns or fabrics including these fibers can include providing a powdered dye or a powdered precursor dye (powdered leuko dye), or providing an aqueous dye formulation or an aqueous precursor dye formulation (an alkaline aqueous leuko dye formulation). An aqueous system including a lipase enzyme can be provided. The fibers/yarn/fabric can be pretreated with the aqueous system, and the pretreated fibers/yarn/fabric can be coated or dyed with the powdered dye or powdered precursor dye, or with the aqueous dye formulation or aqueous precursor dye formulation.

A dyeing process includes weaving patterns on a textile of nylon, CD yarn and polyester; pouring acidic dye, cationic dye and dispersive dye into a dyeing machine; adding auxiliary coloring agent, homogeneous coloring agent and coloring retardant into the dyeing machine wherein the auxiliary coloring agent is prepared by adding 1 g of acetic acid to 1 liter of water to form a solution which is adjusted to have a pH between 4 and 5; the homogeneous coloring agent is prepared by adding 1 g of homogeneous coloring agent to 0.1 kg of textile; and the color retardant is prepared by adding 1 g of sodium sulfate to 1,000 g of water; putting the textile in the dyeing machine to dye as a finished textile. Each pattern woven by a different textile material has a color corresponding to the applied dye. The color of patterns is the color of the dye applied to the patterns.

The present invention relates to a process for producing dyed mixed fibres (D-MF), dyed mixed fibre yarns (D-MY) and/or dyed mixed fibre textile fabrics (D-MT) in which mixed fibres (MF), mixed fibre yarns (MY) and/or mixed fibre textile fabrics (MT) comprising at least one polyester fibre (PF) and at least one further fibre (FF) are simultaneously contacted with at least two different dyes (D1) and (D2) at a temperature T.sub.D<130 C.

Moreover, the present invention relates to the dyed mixed fibres (D-MF), the dyed mixed fibre yarns (D-MY) and/or the dyed mixed fibre textile fabrics (D-MT) obtained by this process.

A metalized fabric and method for metallization of fabric. The fabric is formed using two threads with different affinities for metallization, but which threads are not metalized prior to forming into the fabric. The threads will typically be woven using an unbalanced weave to provide one side of the fabric with a resultant greater amount of metallization than the other but this is not required. Once the resultant fabric is metalized, it will typically be more suitable for consistent color dying than fabric which was formed from both metalized and unmetallized threads.
