“…Wheat gluten and PLA fibers were heated in water at 90°C for 60 min in various pH (3,5,7,9, and 11) conditions to test their stability. The hot water treated fibers were tested and compared to the untreated controls for the changes in tensile properties.…”

Protein fibers with mechanical properties similar to those of wool and better than those of soyprotein and zein fibers have been produced from 100% wheat gluten. Wheat gluten is a low cost, abundantly available, and renewable resource suitable for fiber production. A simple production method has been developed to obtain high-quality wheat gluten fibers, and the structure and properties of the fibers have been studied. Wheat gluten fibers have breaking tenacity of about 115 MPa, breaking elongation of 23%, and a Young's modulus of 5 GPa, similar to those of wool. Wheat gluten fibers have better tensile properties than soyprotein-and casein-based biomaterials. In addition, the wheat gluten fibers have resistance similar to that of PLA fibers to water in weak alkaline and slightly lower resistance in weak acidic conditions at high temperatures.

“…[7][8][9][10][11] Similarly, attempts have also been made to use plant proteins such as soybeans, corn, and peanut and also milk proteins (casein) for fiber production. Reports are available on the commercial scale production of fibers from these sources during the 1930s and 1940s.…”

“…15 Generally, the percentage crystallinity of cellulose fibers such as cotton, jute and flax is about 65-70%, whereas some natural cellulose fibers obtained from agricultural byproducts have crystallinities of about 35-50%. [18][19][20][21][22][23] The moisture regain of milkweed floss is higher than that of kenaf fibers and the density of the milkweed floss is 0.893 g cm −3 . Figures 2 and 3 show the longitudinal and cross-sectional morphologies, respectively, of the milkweed floss fibers.…”

Lightweight composites are preferred for automotive applications due to the weight restrictions and also due to the presence of inherent voids that can enhance the sound absorption of these composites. The density of the reinforcing materials plays a crucial role in such lightweight composites. Milkweed is a unique natural cellulose fiber that has a completely hollow center and low density (0.9 g cm−3) unlike any other natural cellulose fiber. The low density of milkweed fibers will allow the incorporation of higher amounts of fiber per unit weight of a composite, which is expected to lead to lightweight composites with better properties. Polypropylene (PP) composites reinforced with milkweed fibers have much better flexural and tensile properties than similar PP composites reinforced with kenaf fibers. Milkweed fiber‐reinforced composites have much higher strength but are stiffer than kenaf fiber‐reinforced PP composites. Increasing the proportion of milkweed in the composites from 35 to 50% increases the flexural strength but decreases the tensile strength. The low density of milkweed fibers allows the incorporation of higher amounts of fibers per unit weight of the composites and hence provides better properties compared to composites reinforced with common cellulose fibers with relatively high density. This research shows that low‐density reinforcing materials can more efficiently reinforce lightweight composites. Copyright © 2010 Society of Chemical Industry

“…All celluloses, such as cotton, ramie and wood, have the same polymer and unit cell structures, but the fibers have vastly different properties. 22 Thus, it is possible that the tururi regain value could be associated with the presence of noncellulosic substances and/or the amount of amorphous in relation to the crystalline material in its structure.…”

“…This value is compatible with the values of species of recognized textile employability. According to Reddy and Yang, 22 the unit cell size ranges from 12·0 to 25·0 µm for cotton, 5·0 to 76·0 µm for flax and 15·0 to 25·0 µm for jute.…”

Tururi (Manicaria saccifera Gaertn.) is a non-woven sac, which protects the fruits of the Amazon Ubuçu palm tree.The aim of this study was to use fibers withdrawn from these sacs and from sac strips -in the natural condition and after discoloration -to determine tensile, weight and regain values; additionally, longitudinal and cross-sections were studied using optical microscopy and Fourier transform infrared spectroscopy (FTIR) was carried out. The tensile results of fibers withdrawn from the sacs were 10·5 ± 2% elongation, 18 ± 3·2 cN/tex (175 ± 31 MPa) tenacity and 3·4 ± 0·5 N/tex (33 ± 5 GPa) Young's modulus. These values, in addition to regain (12·0 ± 0·5%) and cross-microscopy, are compatible with those of other lignocellulosic fibers. The results related to the strips were 5·9 ± 1% elongation, 17·6 ± 7·8 MPa strength and 552 ± 288 MPa Young's modulus. There was no significant statistical variation between the tensile characteristics of the fibrous material in the natural condition and after discoloration. The determined weight value was 182 ± 18 g/m 2 . FTIR analysis confirmed the presence of cellulose, hemicellulose and lignin. Finally, considerations about sustainable extraction and technical applications (in handcrafts and composites) of tururi fibrous material were made, presenting its potential to be employed in products, such as utensils, furniture, flooring or construction.
