摘要:
The present invention provides a post-fabrication modification approach for the fabrication of colored and chromic materials and sensors using plasma surface modification to covalently bind the coloring agent to the substrate, thus avoiding leaching of the dye. Advantageously, in said methods, said coloring agent is a dye or pigment linked to a radical sensitive functional group, such as an alkenyl or alkynyl functional group, and is applied to the substrate prior to the gas plasma treatment. The methods envisaged herein are generic in nature, which allow the covalent immobilization of various dyes on different materials. The covalently coated materials after plasma surface modification, particularly the covalently coated chromic materials and sensors, can be used in many different applications, such as protective textile and wound dressing applications.

Methods for spinning, weaving, and finishing fabric and/or cloth containing cotton fibers are disclosed. The methods of the invention are performed at lower ambient, solution and/or working temperatures than is previously known in the art. The reduced temperature processing improves various qualities of the resulting textile products and fabrics and lowers costs of operating the processing facility.
摘要:
The present invention relates to a phase-transfer catalytic colour fixation processing method for a textile. The processing method comprises the following steps: dyeing a natural fibre textile in a supercritical carbon dioxide fluid waterless dyeing system using a disperse reactive dye, and then realizing a reaction fixation of the dye on the fibres using a phase transfer catalyst in the supercritical carbon dioxide fluid. Since the method utilizes the action of the phase-transfer catalyst in the colour fixation stage, an ionized colour fixation reaction accelerator and the like is effectively transferred to the supercritical carbon dioxide colour fixation fluid and solid-phase fibres, thus improving the nucleophilic reactivity of the functional group on the fibres, achieving the colour fixation reaction between the fibres and the dye in the supercritical carbon dioxide fluid conditions, and improving the colour fixation efficiency of the dye on the fibres. The technical method provided by the invention realizes the reaction fixation of the dye on the fibres in hydrophobic fluid conditions, and has the advantages of a high colour fixation efficiency, a simple process, being green and environmentally friendly and the like.

摘要:
Customers obtain customized textile materials by selecting style, shape, size, pattern and color for an undyed textile product. Based on a selection made by the customer, the textile product is transformed by a dyeing operation performed on a single item to yield a product, such as a shirt, pants, or jacket, which has a color and pattern of his or her own choosing, in the size and style he or she desires. The process can be performed in a retail setting using a dye machine which allows the process to be viewed by the customer. Preferably, the textile material is constructed from yarns which include cationic cotton alone or in combination with natural cotton or other natural or synthetic fibers, and using anionic dyes, such as a fiber reactive dye, such that the dye is exhausted during the process and effluent from the dye machine is environmentally friendly without excess dye, salts, and alkalis.

The composition is provided for spray dyeing of a cellulosic, such as cotton, fabric or garment. The composition includes a reactive dye, a wetter, an alkali, and water. The present compositions are made by first mixing the reactive dye, the wetter, and the water to form a solution, and thereafter adding the alkali to the solution.
