However, this puts immense pressure on manufacturers to produce more fiber. While synthetic fibers can be produced cheaply, they have a negative impact on the environment. On the other hand, fibers from wool, sisal, fique, wood pulp (viscose), and man-made cellulose fibers (MMCFs) from cotton cannot alone meet the growing fiber demand without major stresses on land, water, and existing markets using these materials. With a greater emphasis on transparency and circular economy practices, there is a need to consider natural non-wood alternative sources for MMCFs to supplement other fiber types. However, introducing new feedstocks with different compositions may require different biomass conversion methods. Therefore, based on existing work, this review addresses the technical feasibility of various alternative feedstocks for conversion to textile-grade fibers. First, alternative feedstocks are introduced, and then conventional (dissolving pulp) and emerging (fibrillated cellulose and recycled material) conversion technologies are evaluated to help select the most suitable and promising processes for these emerging alternative sources of cellulose. It is important to note that for alternative feedstocks to be adopted on a meaningful scale, high biomass availability and proximity of conversion facilities are critical factors. In North America, soybean, wheat, rice, sorghum, and sugarcane residues are widely available and most suitable for conventional conversion through various dissolving pulp production methods (pre-hydrolysis kraft, acid sulfite, soda, SO2-ethanol-water, and potassium hydroxide) or by emerging cellulose fibrillation methods. While dissolving pulp conversion is well-established, fibrillated cellulose methods could be beneficial from cost, efficiency, and environmental perspectives. Thus, the authors strongly encourage more work in this growing research area. However, conducting thorough cost and sustainability assessments is important to determine the best feedstock and technology combinations.}, number={2}, journal={JOURNAL OF BIORESOURCES AND BIOPRODUCTS}, author={Frazier, Ryen M. and Vivas, Keren A. and Azuaje, Ivana and Vera, Ramon and Pifano, Alonzo and Forfora, Naycari and Jameel, Hasan and Ford, Ericka and Pawlak, Joel J. and Venditti, Richard and et al.}, year={2024}, month={May}, pages={130–159} } @article{tahir_li_moore_ford_theyson_seyam_2024, title={Development of Eco-Friendly Soy Protein Fiber: A Comprehensive Critical Review and Prospects}, volume={12}, ISSN={2079-6439}, url={http://dx.doi.org/10.3390/fib12040031}, DOI={10.3390/fib12040031}, abstractNote={In the first half of the twentieth century, scientific communities worldwide endeavored to diminish dependence on expensive and scarce animal fibers like wool and silk. Their efforts focused on developing regenerated protein fibers, including soy, zein, and casein, to provide comparable benefits to natural protein fibers, such as lustrous appearance, warmth, and a soft feel. The popularity and cost-effectiveness of mass-produced petroleum-based synthetic polymer fibers during World War II diminished interest in developing soy protein fiber. Realizing the ecological degradation caused by fossil fuels and their derived products, a renewed drive exists to explore bio-based waste materials like soy protein. As a fast-growing crop, soy provides abundant byproducts with opportunities for waste valorization. The soybean oil extraction process produces soy protein as a byproduct, which is a highly tunable biopolymer. Various functional groups within the soy protein structure enable it to acquire different valuable properties. This review critically examines scholarly publications addressing soy protein fiber developmental history, soy protein microstructure modification methods, and soy protein fiber spinning technologies. Additionally, we provide our scientific-based views relevant to overcoming the limitations of previous work and share prospects to make soy protein byproducts viable textile fibers.}, number={4}, journal={Fibers}, publisher={MDPI AG}, author={Tahir, Muneeb and Li, Ang and Moore, Marguerite and Ford, Ericka and Theyson, Thomas and Seyam, Abdel-Fattah M.}, year={2024}, month={Mar}, pages={31} } @article{kwon_zambrano_pawlak_ford_venditti_2023, title={Aquatic Biodegradation of Poly(beta-Hydroxybutyrate) and Polypropylene Blends with Compatibilizer and the Generation of Micro- and Nano-Plastics on Biodegradation}, volume={4}, ISSN={["1572-8919"]}, DOI={10.1007/s10924-023-02832-y}, journal={JOURNAL OF POLYMERS AND THE ENVIRONMENT}, author={Kwon, Soojin and Zambrano, Marielis C.

In this research, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) was chosen as a representative organophosphate FR to examine inclusion complex (IC) formation with γ-cyclodextrins (γ-CD) to enhance char formation as well as prevent the unnecessary release of toxic FR chemicals. The addition of ionic salts, sodium chloride (NaCl), and calcium chloride (CaCl2) during the formation increased the yield of IC crystals by up to 50%. However, perfect crystals were formed only when pure IC was formed, devoid of only metal crystals. Continuous melt spinning of cellulose acetate butyrate (CAB) is practically very difficult in the presence of incompatible DOPO in the system. The formed IC was compatible with biopolymer CAB due to hydroxyl groups from γ-cyclodextrin at the periphery. CAB/IC fibers were melt-spun alongside reference pure CAB and CAB/CD fibers. CAB was found to form complexation with CD in the absence of DOPO in the cavity, as corroborated by FTIR and tensile properties. Furthermore, the response to flame was noted as compared to reference pure CAB and CAB/CD fibers.

We present a comprehensive review of textile hybrids or composites capable of self-healing and repairing fabrics against damages across the micro- (µm), meso- (µm – mm), and macro-scale (>mm). The reviewed literature is organized in three sections presenting (i) the chemistry and fabrication principles of designing self-healing fabrics against increasing size scales of repair, (ii) stimuli-driven and autonomous healing, and (iii) the methods to characterize the recovery of wettability, barrier, morphological, mechanical, and other properties. The discussion of mainstream methods for developing self-healing fabrics focuses on coatings, composites, and specialized fabrication techniques required as the damage size grows from µm to mm to >mm. The section on stimuli-driven repair and autonomous recovery discusses the time scales associated with different damage repair, showing how external stimuli provide a higher driving force towards healing and accelerate material restoration than autonomous recovery. Finally, an array of optical, mechanical, and functional characterization techniques is discussed to evaluate the recovery yield and understand the repair mechanisms of the various fabrics.

Dry-jet gel-spinning was used to fabricate poly(vinyl alcohol) (PVA) fibers having 30% or more of the lignin biopolymer. To achieve this goal, 0.45 wt.% of aqueous sodium polyacrylate (SPA, at 0.55 wt.% solids) was added to spinning dopes of PVA dissolved in dimethylsulfoxide (DMSO). SPA served to enable the spinning of fibers having high lignin content (i.e., above 30%) while eliminating the aging of as-spun gel fiber prior to elevated temperature drawing. SPA impedes the migration of acetone soluble lignin from the skin of as-spun gel fibers, because SPA is insoluble in acetone, which is also a nonsolvent coagulant for PVA. PVA fibers having 30% lignin exhibited the highest tenacity of 1.3 cN/dtex (centinewton/decitex) and specific modulus 35.7 cN/dtex. The drawn fiber of 70% lignin to PVA, showed tenacity and specific modulus values of 0.94 cN/dtex and 35.3 cN/dtex, respectively. Fourier Transform Infrared (FTIR) spectroscopy showed evidence of hydrogen bonding between lignin and PVA among the drawn fibers.

This coordinate system was used to quantify the affinity of coagulation baths with respect to the polymer in the spinning solution. A correlation based on radial energy distribution (RED) was seen to consistently differentiate wet from gel spinning. If the HSP distance between the coagulation bath and polymer (Ra) is less than or equal to the inherent interaction radius (R o ) of the polymer (RED ≤ 1), coagulant diffusion inward is observed, which is critical for wet spinning. If Ra is greater than R o (RED > 1), negligible amounts of coagulant diffusion inward is observed, which is critical for gel spinning.
