The present invention relates to a method of obtaining a solid material based on a polymer having its cellobiose units exhibiting the following characteristics: at least some of the cellobiose units have at least one carboxylic acid function attached to the C.sub.6 carbon, the other C.sub.6 carbons having a primary alcohol function attached thereto; and at least some of the cellobiose units have at least one of the two rings open between the C.sub.2 and C.sub.3 carbons, the other C.sub.2 and C.sub.3 carbons forming a ring and having an alcohol function attached thereto.

Such a material, advantageously a textile, may be used as a compress.

A method of using select Schiff base compounds for chemical agent detoxification. The method including applying a compound to the contaminated substrate. The compound includes an imine having at least one Schiff base nitrogen and an alkyl substituent or an aryl substituent having an electron acceptor. The at least one Schiff base nitrogen is spaced away from the electron acceptor by a distance ranging from about 200 pm to about 1000 pm. The substrate and the compound are dried. The at least one Schiff base nitrogen of the compound promotes a nucleophilic attack on an electrophilic site of the toxic chemical agent.

Methods and formulations for controlling parasitic insect infestations, such as human lice infestations, on textiles. In one embodiment, a method includes applying an anti-parasitic formulation to a textile in need of treatment. In one embodiment, an anti-lice formulation includes an effective amount of at least one spinosyn, such as spinosad. In one embodiment, the anti-lice formulation is at least one of an aqueous suspension and an aqueous solution. The anti-lice formulation may also include one or more additional active ingredients and one or more carriers. The anti-lice formulation has parasiticidal activity when applied to a textile. For example, in one embodiment the anti-lice formulation is formulated to produce 100% adulticidal, nymphicidal, and ovicidal activity when applied to a textile in need of treatment.

An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.

An apparatus for processing yarns includes a first roller set for extending yarn beam; a node generator installed after the first roller set for forming node section of the yarn beam; a first cleaning chamber installed after the node generator for cleaning the yarn beams; a material chamber for adding additive to the yarn beam; a second roller set installed after the material chamber for extending the yarn beam; a first heating chamber installed after the second roller set for thermally setting additives to the yarn beam so that the additives are firmly secured to the yarn of the yarn beam; a third roller set installed after the heating chamber for controlling the heating time of the yarn beam in the first heating chamber; and a fourth roller set installed after the third roller set for winding the yarn beam to a desired shape.

A mold-preventing air filter filtration medium loaded with a water-retaining macromolecule polymer, a mold-preventing agent, and a binder resin, is formed by immersing a filter material or a reinforcing nonwoven fabric (a backing material) in a mold-preventing composition in which the water-retaining macromolecule polymer, the mold-preventing agent and the binder resin are dissolved, and drying the filter material or the reinforcing nonwoven fabric. The reinforcing nonwoven fabric (a backing material) may be bonded to a filter material to form a mold-preventing air filter filtration medium. A mold-preventing air filter includes the mold-preventing air filter filtration medium that is pleated and accommodated in a frame.
