A composite fiber may include at least one reinforcing filament formed of a first material. A second material maybe systematically deposited in a printed onto the at least one reinforcing filament such that at least one of a length, a width, and a thickness of the second material varies across a surface of the at least one reinforcing filament. The printed pattern may alter one or more properties of a composite structure containing the composite fiber.

Disclosed is a napped artificial leather dyed with a cationic dye, including: a non-woven fabric of a cationic dyeable polyester fiber having a fineness of 0.07 to 0.9 dtex; and an elastic polymer provided inside the non-woven fabric, wherein the napped artificial leather has L* value?50, a grade of color difference determined in an evaluation of color migration to PVC under a load 0.75 kg/cm at 50? C. for 16 hours, of 4 or more, a tear strength per mm of thickness of 30 N or more, and a peel strength of 3 kg/cm or more.

Embodiments of the present disclosure are directed to a performance garment having a realistic visual effect of being constructed from abraded denim. The performance garment comprises a number of fabric panels that are adjoined together to form the garment. Each fabric panel is made of a stretch performance fabric that contains at least 50% polyester and at least 10% of one or more elastomeric materials. Each fabric panel is printed with a pattern that provides the fabric panel with the visual effect of abraded denim. For instance, each fabric panel may be printed with an original digital pattern that was not produced from imaging a denim garment.

The invention provides a process for tanning a substrate using at least one ionic liquid. The at least one ionic liquid can be used in at least one of the following tanning steps: tanning, re-tanning, preservation, liming, pickling, impregnation, lubrication, dyeing, fatliquoring or finishing.

The present disclosure provides methods for making synthetic hair compositions. The methods generally comprise providing a plant fiber, degumming the plant fiber, and dyeing the plant fiber. The present disclosure also provides methods of degumming banana fiber. The methods generally comprise providing banana fiber and soaking the banana fiber in a degumming solution comprising a base, magnesium sulfate, and hydrogen peroxide. The present disclosure further provides methods of dyeing banana fibers. The present disclosure further provides synthetic hair compositions comprising banana fibers made by the methods described herein.

Provided herein is a dyed substrate with at least 70 wt. % of dyed PLA-fibres having a poly(lactic acid) content of at least 70 wt. %, the dyed substrate having a total poly(lactic acid) content of at least 70 wt. %. The dyed PLA-fibres are dyed with one or more disperse dyes, and the dyed substrate has the following CIELAB colour: 0L*25; 5a*5; and 5b*5. A method of preparing the dyed substrate is also provided.

A dyeing system includes a conveyance device, a reader, a dye fixing device, and a controller. The conveyance device conveys a conveyance unit including the resin body. The reader reads information relating to the conveyance unit. The dye fixing device heats the resin body in the conveyance unit conveyed by the conveyance device and fixes a dye adhering to a surface of the resin body, on the resin body. The controller acquires a parameter for a process executed to the resin body in the conveyance unit, based on the information read by the reader. The controller controls the dye fixing device based on the acquired parameter.
