摘要： There is provided a process for chemically pretreating reclaimed cellulose fibres to be used in the production of moulded bodies from regenerated cellulose, wherein the pretreatment includes one stage, in which stage acid metal removal and acid oxidative bleaching are carried out together. Advantages include that the propensity of the regenerated cellulose to clog when flowing in a tube and through a nozzle is reduced. This is believed to be an effect of an efficient metal removal. The need for additional bleaching steps and/or metal removing steps is reduced or even eliminated. A one-stage method is more efficient, faster and less costly compared to a multi-stage method according to the prior art. From an environmental perspective, acidic metal removal is preferred over removal by chelating agents such as EDTA.

摘要： A method for producing a carbon fiber opened sheet 8 is provided. The method includes performing a surface activation treatment on an unopened tow of carbon fibers (3a, 3b) to which a sizing agent has been applied, and opening the unopened tow of carbon fibers (3a, 3b) into a sheet. The opening process preferably uses at least one set of opening devices. The set of opening devices includes a holding shaft (4a-4d, 5a-5d) for bending and conveying the unopened tow of carbon fibers (3a, 3b), and an opening bar (6a-6c) that vibrates in the width direction of the unopened tow. A difference in height ΔH between the end of the holding shaft (4a-4d, 5a-5d) and the end of the opening bar (6a-6c) is preferably 5 to 30 mm. With this configuration, even if a sizing agent is applied to the unopened tow of carbon fibers, the filaments are easily separated from each other and the tow is easily opened. Thus, the carbon fiber opened sheet is less likely to have a defect.

摘要： Substrates are coated with a curable composition that includes at least one free radical polymerizable monomer and a heat-activated polymerization initiator. The coating is applied to the substrate and cured thereon to produce the coating. Curing is performed by purging molecular air from the vessel containing the substrate, pressuring with an oxygen-deficient gas and then curing the fabric in the oxygen-deficient gas at elevated pressure and temperature.

摘要： Disclosed is a method for producing a modified animal fiber, the method includes step 1 (31, 32) of pre-oxidizing a cystine bond (-S-S- bond) present in an epidermal cell of an animal fiber to bring the cystine bond into a low oxidation state, step 2 (33) of oxidizing with ozone the pre-oxidized -S-S- bond to bring the -S-S- bond into at least one high oxidation state selected from di-, tri-, and tetra-oxidation states, and step 3 (34) of reductively cleaving the -S-S- bond in a high oxidation state. The method imparts shrink resistance and pilling resistance to an animal fiber. In the step 2 (33) ozone is microdispersed in an aqueous solution comprising an anionic surfactant having a C 8-24 alkyl group, and the animal fiber is contacted with the ozone. Accordingly, the present invention provides a method for efficiently producing in a short period of time an animal fiber having excellent shrink resistance that barely undergoes felting when washed in an aqueous system in shrink proofing an animal fiber using ozone.

摘要： Modified cellulosic fibers are formed by (1) esterifying cellulosic fibers with a 1,2-disubstituted alkene that has at least one carboxylic acid group reactive with cellulosic hydroxyl groups and (2) oxidizing the esterified fibers to form aldehyde groups. The modified fibers are useful in paper products, which tend to have temporary wet strength. Strength additives may be included in the paper product to impart a higher level of temporary wet strength or permanent wet strength.
