Abstract: A system for manufacturing graphene nanoribbon by continuous microwave is disclosed. The system comprises a microwave heating tank for heating carbon nanotube through microwave, a reaction tank for adding an oxidizing or reducing agent and a pipeline for connecting all devices of the system. A feed rate is controlled by a pump to enter raw material into the system via the pipeline, the nanotube is made to be a graphene nanoribbon by heating, adding the oxidizing agent, reheating, adding the reducing agent and reheating. Therefore, the graphene nanoribbon could be mass produced automatically in a short time.

Abstract: A method for authenticating a textile product, wherein a colorless composition is applied to at least one portion of at least one thread of the textile product. The composition comprises one of a pair of a colorformer and an activator which react when mixed to produce a spectral response. The textile product is authenticated as genuine by applying the other of the pair of the colorformer and activator to at least one portion of the at least one thread to produce the spectral response. The textile product may be a thread or a woven label.

Abstract: Compositions and methods for removing oily soils from fabrics involving treatment with specific mixtures of solvents and solvent soluble emulsifiers in an aqueous washing medium. The compositions herein can be employed singly in aqueous washing media to remove oily materials from fabrics or can be admixed with other materials suitable for use in a laundry procedure.

Abstract: A processing aid is used to improve worsted and woolen processes. In the worsted process, pretreatment of wool tops with the processing aid prior to dyeing preserves fiber strength and softness. In the woolen process, addition of the processing aid to the carbonizing bath permits reduction in sulfuric acid concentration, enhances destruction of vegetable matter, and produces whiter, cleaner fiber and preserves fiber strength. If desired, the processing aid may also be introduced in the final rinse after wool scouring in either worsted or woolen processes. The preferred processing agent is epoxidized chain extended polyamide.

Abstract: Cellulosic material present in admixture with or as impurities in wool or other non-carbonizable fibres is carbonized by treating the fibre substrate, which may be in any form from loose fibre to fabric, with a solution of an anhydrous acid in an inert organic solvent. The treated fibrous substrate is then dried and can be beaten, rinsed and further dried if necessary. The preferred solvents are aliphatic hydrocarbons or chlorinated aliphatic hydrocarbons and the acid may be an inorganic acid such as hydrochloric acid or an organic acid such as trichloracetic acid. The method can be applied to unscoured or undesized wool, in which case the wool is cleaned at the same time as cellulosic materials are being carbonized. The solvent may advantageously contain up to 100 g/l trioxan. The method can be applied by impregnating the fibrous substrate with the organic solvent and subsequently exposing the impregnated substrate to the acid, which may be gaseous hydrogen chloride.

Abstract: Disclosed is a method of producing a carbon fiber felt which includes the steps of preparing a substantially unidirectional array of continuous carbonizable filaments in oxidized state, cross-laying other such filaments on one side of said array in a state of restraint from displacement from their cross-laid relationship, and needle-punching the resulting assembly from the same side.Also disclosed is a method of pre-sizing a high bulk, low density carbon fiber felt comprising the steps of impregnating said felt with a thermoplastic or thermosetting resin highly diluted in a solvent, and removing said solvent either before or while the assembly is being reduced to its final dimensions to leave the resin per se as a coating on the fibrous material serving to adhere individual elements together at cross-over points to prevent displacement thereof, all prior to the addition of the matrix material in which the carbon fiber is embedded to form the final composite.
