摘要:
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.

摘要:
A chromic luminescent composition and method for fabricating the composition are disclosed. The chromic luminescent composition comprises at least one or more non-luminescent materials and one or more luminescent materials. The one or more non-luminescent materials having absorption spectra that at least partially overlap with the spectrum of incident electromagnetic radiation. The one or more luminescent materials convert at least a portion of energy of incident electromagnetic radiation to a lower energy wavelength. The one or more non-luminescent materials and the one or more luminescent materials are selected such that, when subsequently exposed to incident electromagnetic radiation, color and brightness are substantially modulated through absorption and emission as a function of incident electromagnetic radiation. Also disclosed are a chromic luminescent textile and a method for fabricating the textile.

Disclosed are various embodiments for dyeing a material using a dyed nanocellulose dispersion, thereby reducing or eliminating the need for water in dyeing materials, such as fabrics and textiles. A dyed nanocellulose dispersion or gel may be prepared from wood pulp fibers using a homogenizer and a dye, wherein the dyed nanocellulose dispersion comprises nanosized cellulose fibrils. The dyed nanocellulose gel may comprise an approximate concentration of 0.5% to 6%. The dyed nanocellulose dispersion may be applied to a material, such as a fabric or textile material. The fabric or textile material can be dried resulting in a dyed material.
摘要:
A pigment for ink-jet recording contains a porous particle, a sealing agent, and an inorganic pigment layer containing an inorganic pigment. The sealing agent is arranged in a pore opening of the porous particle. The inorganic pigment layer is formed on the surface of the porous particle.
摘要:
The present invention concerns polymeric-enveloped microparticles including at least one HASE type acrylic copolymer, at least one solid-liquid phase change material with a phase transition temperature ranging from 20 to 90° C., and at least one active agent. In particular, the microparticles include at least one HASE type acrylic copolymer including at least one anionic monomer with a polymerizable vinyl group and a carboxyl group, at least one non-ionic hydrophobic monomer with a polymerizable vinyl group, and at least one alkoxylated associative macromonomer with a polymerizable vinyl group and a hydrophobic hydrocarbon chain.
