The present disclosure provides a polyamide 5X staple fiber, a preparation method and use thereof. The polyamide 5X staple fiber has a denier of 8.0-30.0D, a breaking strength of 2.0-6.0 cN/dtex, and an elongation at break of 30-100%. The polyamide 5X staple fiber has good mechanical properties and softness, and a blended wool yarn for manufacturing carpets with good mechanical properties, dyeability, and wear resistance can be obtained by using the polyamide 5X staple fiber.

A dye for a material with amide functional groups and a dyeing method of using the same are provided. The dye includes a compound represented by Formula (I) and a solvent. Based on the total weight of the dye of 100 wt %, a content of the compound represented by Formula (I) is 40 wt % to 95 wt %.

In Chemical Formula (I), R.sub.1, R.sub.2 and R.sub.3 are each independently H, —OH or —COOH, wherein at least one of R.sub.1, R.sub.2 and R.sub.3 is —OH or —COOH.

The present invention relates to a composition for printing a fiber blend, yarn, woven or non-woven or knit fabric comprising or consisting of at least acrylic, aramid, and optionally wool, a process for producing the composition, use of the composition, a process for printing said fiber blend, yarn, woven or non-woven or knit fabric, as well as to the printed fiber blend, yarn, woven or non-woven or knit fabric and the use thereof to manufacture goods like cloths therefore.

This disclosure relates generally to the preparation of eco-friendly engineered fabric, and more particularly to terry fabric and variations thereof. In one embodiment, a terry fabric is comprised of a soluble fiber blend, blended with cotton fibers, where the soluble fibers are dissolved in a caustic or enzyme solution to create highly porous yarns.

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 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.

An aqueous ink composition for ink jet textile printing contains: lithium ions; sodium ions; and a dye in which a plurality of ligands represented by any of formula (1), formula (2), and formula (3) coordinate to a metal atom.

Yarns are described herein which, in some embodiments, comprise plies or single strands dyed with at least one vat dyestuff yielding a tweed or heathered appearance. In one aspect, a yarn comprises a first ply and a second ply each dyed with at least one vat dyestuff, wherein a difference in color depth (DL*) between the dyed first single strand and the dyed second single strand has an absolute value of at least 2 when the vat dyestuff is in an oxidized state. As described further herein, the first ply and the second ply are dyed in the same dyebath. In another aspect, a yarn comprises a first ply and a second ply each dyed with at least one vat dyestuff, wherein a reflectance ration between the second ply and the first ply ranges from 0.05 to 0.95.

A textile material exhibiting enhanced energy absorption (e.g., enhanced near-infrared energy absorption) and, optionally, flame resistance. The textile material comprises a textile substrate and a finish disposed on at least one surface of the textile substrate. The finish comprises a binder and an energy-absorbing agent. A method for protecting an individual from infrared radiation that can be generated during an arc flash comprises the step of positioning a textile material between an individual and an apparatus capable of producing an arc flash.
