An integrated and improved, single-step, process for the production of a carbon fiber precursor is described, specifically a process which starts from the comonomers and reaches the spinning step, obtaining the final precursor fiber.

A continuous process for the recycling of aramid fiber comprising the following steps: combining aramid fibrous material including non-continuous aramid fibers with sulfuric acid to obtain a spin dope comprising aramid, and processing the spin dope including aramid into a continuous aramid fiber. The invention also pertains to a continuous aramid fiber, preferably obtainable by said process, and to a multifilament yarn including the continuous aramid fiber.

The present disclosure provides a fabric, a preparation method thereof and clothing formed therefrom. The preparation method includes the following steps: obtaining bio-based synthetic fiber chips from textile waste materials; obtaining extruded filaments from the bio-based synthetic fiber chips by adopting a spinning solution; and weaving and interlocking the extruded filaments with bio-based elastic fibers to obtain the fabric. The prepared fabric is obtained from the textile waste materials, so that waste recycling is realized, and the pollution of the textile wastes to the environment is avoided. The spinning solution is adopted in the preparation process of the fabric, so that the opacity and hydrophilicity of the fabric can be enhanced.

A nonwoven recyclable fabric and associated methods are provided. The fabric is formed from 100% polyester, and may also include surface coatings such as hydrophilic coatings to promote heat transfer as well moisture vapor transmission rates and/or a silicone coating to promote fabric smoothness and reduce abrasiveness of the fabric.
