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.

An apparatus includes a process chamber, a controllable compressor for pressurizing a fluid, a pressure reducing member, an inlet for a processing agent and a controller. The process chamber is a pressure chamber. The controllable compressor pressurizes a fluid and introduces the pressurized fluid into the process chamber from a source. Further the controllable compressor controls a predefined pressure in the process chamber to reach a supercritical state of the fluid. An inlet for a processing agent facilitates introduction of the processing agent into the process chamber prior to, during, or subsequent to pressurization of the fluid. The pressure reducing member reduces the pressure of the fluid at least to reach a gaseous state subsequent to processing the leather object such that the time for reduction of pressure exceeds a predefined reduction period or the reduction of pressure does not exceed a predefined leather pressure reduction gradient.

In one aspect, a method for permeating color into components includes the step of placing substrates inside a carrier. The method includes the step of placing the carrier inside an ultrasonic cleaning tank of an ultrasonic cleaning machine. The method includes the step of performing an ultrasonic cleaning in the ultrasonic cleaning tank. After the ultrasonic cleaning, the method transports the carrier with a robotic arm to a washing tank. The method includes the step of inserting, with the robotic arm, the carrier into the washing tank and neutralizing a substrate with water in the washing tank. The method includes the step of feeding warm water into a channel of the washing tank up to a specified level. The method includes the step of steaming the washing tank for a specified steaming time.

A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and aramid fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a plurality of polyphenylene sulfide fibers and aramid fibers; (b) spinning the blend of fibers into a plurality of yarns; (c) forming the yarns into a textile material; (d) subjecting the textile material to a polyphenylene sulfide dyeing process.

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.
