摘要： The present invention relates to the field of textiles. More specifically, it pertains to a process for producing and using fibrillated biodegradable microfibers.
The process involves sourcing and preliminary processing plant materials encompassing cellulose-rich fibers followed by mechanical compression method or a solar powered electric presser to expel surplus moisture. Then, an aqueous immersion technique is employed for thermal processing to obtain thermal processed plant materials. The thermal processed plant materials then undergo a rinsing step and a mechanical disintegration step to reduce the thermal processed plant materials into micro-sized entities while maintaining the integrity of the fibers. Furthermore, matrix forming substances, stabilizer, sealant and preservative to said micro-sized entities subsequently undergoing a blending process to obtain a first mixture. Lastly, the first mixture is exposed to a controlled desiccation regimen followed by implementing a mechanical reduction process resulting in the attainment of said fibrillated biodegradable microfibers with a diameter measurement below the threshold of 10 μm.

摘要： Methods for the recycling of carpet are disclosed that produce clean face fiber suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester or a polyamide, from carpets that includes a face fiber material and a backing material, and include the steps of heating the carpet to a temperature lower than the melting point of the face fiber material, but higher than the initial thermal decomposition temperature of the backing material, for a time and at a temperature sufficient to thermally decompose, pyrolyze, or oxidize at least a portion of the backing material, rendering the backing material friable, that is more friable than the untreated backing; and applying mechanical force to the carpet so as to liberate the friable backing material from the face fiber material.

摘要： Various embodiments of the present invention relate to surface enhanced pulp fibers, various products incorporating surface enhanced pulp fibers, and methods and systems for producing surface enhanced pulp fibers. Various embodiments of surface enhanced pulp fibers have significantly increased surface areas compared to conventional refined fibers while advantageously minimizing reductions in length following refinement. The surface enhanced pulp fibers can be incorporated into a number of products that might benefit from such properties including, for example, paper products, paperboard products, fiber cement boards, fiber reinforced plastics, fluff pulps, hydrogels, cellulose acetate products, and carboxymethyl cellulose products. In some embodiments, a plurality of surface enhanced pulp fibers have a length weighted average fiber length of at least about 0.3 millimeters and an average hydrodynamic specific surface area of at least about 10 square meters per gram, wherein the number of surface enhanced pulp fibers is at least 12,000 fibers/milligram on an oven-dry basis.

摘要： An apparatus for processing a fibrous material batt like lint cotton to increase the moisture content of the material and to compress the batt of humidified fibers to increase the batt density. A stream of warm humid air is passed through the moving batt of fiber that is constrained between a rotatable hollow cylinder and a stationary perforated screen. The air passing through the batt of figure removes debris from the batt and carries the debris to an associated plenum. The batt is doffed off the rotatable cylinder by a roller that serves to both doff and compress the batt. A roller doffs the fiber batt from the rotatable cylinder and doffs and compresses the batt against a compression roller.

摘要： A drum separator includes a cylindrical screen drum which is mounted for rotation within a sealed housing such that a small portion of the perimeter of the screen drum is exposed. Air, fibers, and fines are introduced onto a first part of the exposed portion of the screen drum and fines and air pass through the screen drum into the interior of the housing and then to a fines collector. Fibers which are too large to pass through the screen drum are carried by the rotation of the screen drum to a pick-up head which applies a low pressure to the exterior of the screen drum to remove the fibers. The pick-up head is pivotably mounted to the housing, and air cylinders lift the pick-up head away from the screen drum in the event of an impact. The pick-up head includes a pick-up bar and a plurality of fins which are shaped to optimize removal of fibers from the exterior of the screen drum.
