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 ?m.

A system and method for creating a rigid foam substitute is provided. By using natural binding materials and natural fiber materials, the system and method may be used to create environmentally friendly substitutes for expanded polystyrene. The system generally comprises a processing room and molding facility. The processing room may comprise an opener, cleaner, and blower, which may be used to break up and clean the natural fiber material. The molding facility may comprise a mixer, molder, and kiln, which may be used to create casts. The method generally entails processing a natural fiber material before mixing it with a natural binding material and fluid to create a fluidic mixture, wherein said fluidic mixture is subsequently molded and cured to create a finished product.

A screw feeder includes: a case that includes a material putting-in portion through which a fluff material is put in and a material putting-out portion through which the fluff material is put out below the material putting-in portion; and a screw that includes a rotational shaft and a blade portion, the rotational shaft being provided rotatably inside the case, the blade portion being spirally mounted on the rotational shaft; wherein the screw is rotated with repeated alternation of a slope-down direction in which the blade portion slopes downward spirally in a vertical direction and a slope-up direction in which the blade portion slopes upward spirally in the vertical direction.

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.
