  • Patent number: 11377788
    Abstract: Methods are directed to the use of a supercritical fluid for finishing a target material with a finishing material. One or more variables selected from temperature, pressure, flow rate, and time are manipulated to increase efficiencies in the finishing process. As temperature or pressure are decreased causing a change in the density of a supercritical fluid carbon dioxide, which in turn causes a precipitation of dissolved material finish with the carbon dioxide, other variables are maintained above threshold values to increase the uptake of the material finish by the target material. This improvement reduces time by limiting cleaning processes of the system, saves materials used in the cleaning process, and saves energy used to achieve cycles of the process, in aspects.

  • Patent number: 9856376
    Abstract: Films with optical transmittance of >80% between 400 and 750 nm and with coefficient of thermal expansion less than 20 ppm/° C. are prepared from aromatic polyamides that are soluble in polar organic solvents yet have glass transition temperatures >300° C. The films are crosslinked in the solid state by heating at elevated temperatures for short periods of time in the presence of multifunctional epoxides. Surprisingly, the optical and thermal properties of the films do not change significantly during the curing process. The temperature required for the crosslinking process to take place can be reduced by the presence of a few free, pendant carboxyl groups along the polyamide backbones. The films are useful as flexible substrates for electronic displays and photovoltaic devices.

  • Patent number: 8999005
    Abstract: A process obtains an aged or faded effect on garments made of protein fibers such as wool, cashmere and silk. Granules of inert materials, which are particularly light in order not to damage very fine fibers, are introduced into a tumbler. The garments were previously treated with a chemical product commonly referred to as “dye retardant” for inhibiting dyeing of the fabric. The tumbler is pre-arranged so that the chemical product does not migrate through holes or openings. Raw confectioned garments that are to be treated, such as jerseys or outerwear, are introduced into the tumbler. The garments are extracted from the tumbler at the end of migration of the chemical product for inhibiting dyeing of the outer surface of the garments by the granules and steamed in an autoclave to fix the chemical process of the product for inhibiting dyeing of the outer surface of the garments. The garments are then dyed with a specific selection of dyes that must be defined each time according to the desired result.

  • Patent number: 8784503
    Abstract: The invention relates to a high-strength and abrasion-resistant fibrous material and to a method for the production thereof. According to said method, a natural fiber material is solubilized in an alkaline manner. The fibrous material is treated with an alkaline material, without being subjected to mechanical stress a) at a temperature of between 5 and 30° C. and then b) at a temperature of between 80 and 150° C., and is then optionally washed and/or dried.

  • Patent number: 8771571
    Abstract: A method for preparing a polyglutamic acid (?-PGA) fiber having antibacterial and water absorption properties is provided. The method includes providing a ?-PGA fiber and immersing it in a sodium hypochlorite solution. A relation exists between an immersing time T of the ?-PGA fiber and a concentration X of the sodium hypochlorite solution as shown in the formula below: 10.2?(T?64.55X2+50X)?15.2, wherein X is 0.006-0.4 wt %.

  • Publication number: 20140178457
    Abstract: The application concerns a Binder (comprising sulfamic acid, ammonium sulfamate and ammonium sulfate) and process of production of fabrics containing cyclodextrins fixed to the binder. The technology allows fixing a binder to natural, synthetic or artificial fibers, and, by means of a thermal processes, to fix cyclodextrins to the same binder, giving rise to fabrics suitable to incorporate active principles and to release them along with time. Peculiar characteristics of the binder are its abilities to interact with several types of fabric, independently of their composition, and with several types of cyclodextrin. Other peculiarities of embodiments are: the ability to produce functionalized fabrics, adapted to be weighted with desired molecules and release them gradually along time, with a process that does not alter the original characteristics of the fabric; the possibility of repeating several times the weighting of such molecules, so as to be able to define such fabrics as “reloadable” or “rechargeable.

  • Patent number: 8690964
    Abstract: A method for treating a fabric for protection from ultraviolet radiation is disclosed which comprises the steps of dispensing a suspension of zinc oxide particles treated with an acid polymer into a washing machine during a time in which a fabric is being washed in the washing machine and mixing the treated zinc oxide particles and the fabric for the treated zinc oxide particles to bind to the fabric. Other methods for treating a fabric for protection from ultraviolet radiation are also disclosed.

  • Patent number: 8608807
    Abstract: An ecological fabric having protection from ultraviolet radiation incorporated therein is disclosed in which the fabric is treated by a method comprising the steps of dissolving zinc acetate or other zinc salt in a liquid to form a solution containing Zn(II) ions, adding a fabric to the solution, mixing the solution and the fabric, and adding a base to the solution when the solution and the fabric are being mixed to form a suspension of zinc oxide nanoparticles in contact with the fabric. Other methods are disclosed such as modifying a fabric by carboxylation or phosphorylation of the fabric followed by binding of the UV-blocking nanoparticles to the modified fabric and modifying UV-blocking nanoparticles with a self-assembled monolayer (SAM) or polymer layer containing an active chemical group capable of binding to the fabric and depositing the UV-blocking nanoparticles on the fabric.
