The present description discloses a Textile Product having applied thereon with a treating composition, said composition comprising an extract of a pine needle in a concentration of 1% to 8% by weight of the Textile Product; wherein the said Textile Product has anti-microbial, anti-odor, anti-fungal, anti-oxidant, insect repellent, aromatic and an additive binding properties, and optionally an additive. The additive is selected from a group comprising of a herbal extract having insect & moth repellent properties; a herbal extract having medicinal properties; a piezoelectric effect mineral powder; a natural aroma and fragrance; natural dye, synthetic/chemical dye.

The disclosure provides a dyeing method using bio-dye. A first compound containing an X group is reacted with a second compound containing a Y group to form a third compound, in which the X group is selected from the group consisting of an isocyanate group, a carbodiimide group, an aziridinyl group and an epoxy group, the Y group is selected from the group consisting of a hydroxyl group and an amine group, and the second compound is an amine compound and contains two or more Y groups. Cationization of the third compound is carried out with a fourth compound containing a carboxyl group to form a cationic modification agent. A cationic modification treatment is performed on a fiber material by using the cationic modification agent to form a cationized fiber material. Thereafter, a dyeing treatment is performed on the cationized fiber material through a dye solution containing bio-dye to color the cationized fiber material.

A method for processing textile fibers is provided. The method comprises: adding a plurality of raw materials for processing textile fibers into a plurality of kettles; preparing supercritical carbon dioxide; obtaining one or more natural plant dyes and one or more natural plant extracts from the plurality of raw materials, and dissolving the one or more natural plant dyes and the one or more natural plant extracts in the supercritical carbon dioxide; dyeing and functionally modifying the textile fibers simultaneously by using the supercritical carbon dioxide carrying a mixture of the one or more natural plant dyes and the one or more natural plant extracts; performing a post-process to recycle the supercritical carbon dioxide; and performing a cleaning process to clean the one or more natural plant dyes and one or more natural plant extracts.

A leuco dye pastel marking device for use with a substrate treated with an activator of the leuco dye, such that drawing upon the substrate will reveal a color, but drawing on a normal surface will have no visible effect. A solvent such as dimethyl adipate is used to store the leuco dye in a longer-lived, more stable, solid form, and varying hardnesses and consistencies may be achieved by the addition of 12 hydroxystearic acid and ethyl cellulose. The substrate may be treated selectively with the activator such that a texture, image, or hidden message is revealed by the application of the leuco dye pastel to the substrate. One or more substrates and one or more leuco dye pastel marking devices may be presented to a child as a coloring book with pastels that only visibly mark the coloring book and no other surface.

Methods for obtaining natural colorants from plant material (e.g., tobacco material) and for using such natural colorants to dye various substrates are provided. Natural colorants are obtained using particular enzymes and particular conditions (e.g., time, temperature, and pH profiles). Such colorants can be used to dye substrates, for example, using conventional dyeing techniques or using unique in situ methods.
