“…Under current practices, high amount of poly(vinyl alcohol) (PVA) textile sizes are being consumed annually for slashing/sizing which is an indispensable process during textile processing. [ 1,2 ] Due to the extensive use and need to desize the yarns after fabric formation, over 1 million tons of PVA sizes is being released as effluent every year. [ 3 ] PVA contains non‐biodegradable petro‐based chemicals which contribute to serious wastewater pollution.…”

Poly(vinyl alcohol) (PVA) sizes are widely used in textile industry due to their excellent sizing properties on synthetic fibers and their blends. However, PVA contains non‐biodegradable chemicals and is a major contributor to environmental pollution related to the textile industry. To overcome this problem, an environmental‐benign and highly thermal‐resistant yarn coating is fabricated from soy proteins, an agricultural byproduct. The soy proteins are chemically modified by glycols having varying chain lengths and number of hydroxyl groups. Compared with the physically modified soy proteins and their sized yarns, coating made from the soy proteins esterified by 1,4‐butanediol show 91.38% increment in work of rupture at 120 °C and cotton/polyester (65/35) yarns sized by 1,4‐butanediol esterified soy protein sizes have 39.91% decrease in coefficient of friction. In addition, 1,4‐butanediol esterified soy sizes have a five‐day biochemical oxygen demand/chemical oxygen demand of 0.476, indicating that the chemically modified soy sizes have high biodegradability in activated sludge. Successful utilization of modified soy sizes can promote large‐quantity applications of soy byproducts, impelling high value addition to agricultural byproducts and sustainability of textile industry.

“…Especially for warp yarns before weaving, PVA (polyvinyl alcohol) is an often used sizing agent which also increases the abrasion resistance of cotton yarns [5]. Due to its missing biodegradability, tests were performed to replace PVA by soymeal [6]. Loading polyester fabrics with TiO 2 nanoparticles in a high-temperature pressure exhaustion process could increase washing and abrasion resistance of the fabrics, in addition to the main aim of self-cleaning properties [7].…”

Textile fabrics are often subject to abrasion, starting from exposed parts of garments to a variety of technical textiles. Abrasion protection by usual coatings, however, can significantly decrease the water vapor transport through a fabric which is often not desired, especially in the case of garments. In our paper, we report on an approach to combine increased abrasion resistance with sufficient water vapor transport properties. For this, different polymers (poly(methyl methacrylate), acrylonitrile butadiene styrene, or amorphous polyamides) were coated on cotton and polyester woven fabrics. The results of abrasion tests against sandpaper show significantly increased abrasion resistance. The absolute evaporation resistance, measured by a Permetest testing device, was only slightly increased up to values still acceptable for typical garments. Images of all coatings by helium ion microscopy deliver an explanation for the measuring results. Polymer coatings on the polyester fabric resulted in a slight reduction of the hydrophobicity, while coating the cotton fabric severely increased the contact angles of the originally superhydrophilic material.

“…These proteins have been studied for different applications. For example, Yang et al used soy protein (Xu et al, 2014a) and keratin (Xu and Yang, 2014) for fiber fabrication, and Zhao et al developed textile auxilliaries and biomedical scaffolds from them (Zhao et al, 2016a and2016b;Xu et al, 2014b;Xu et al, 2016). However, the complicated fabrication process of fibers and limited market demand for scaffolds restricted the industrialization of proteins.…”

Fully biodegradable textile sizes with satisfactory performance properties were developed from soy protein with controlled hydrolysis and dis-entanglement to tackle the intractable environmental issues associated with the non-biodegradable polyvinyl alcohol (PVA) in textile effluents. PVA derived from petroleum is the primary sizing agent due to its excellent sizing performance on polyester-containing yarns, especially in increasingly prevailing high-speed weaving. However, due to the poor biodegradability, PVA causes serious environmental pollution, and thus, should be substituted with more environmentally friendly polymers. Soy protein treated with high amount of triethanolamine was found with acceptable sizing properties. However, triethanolamine is also non-biodegradable and originated from petroleum, therefore, is not an ideal additive. In this research, soy sizes were developed from soy protein treated with glycerol, the biodegradable triol that could also be obtained from soy. The soy sizes had good film properties, adhesion to polyester and abrasion resistance close to PVA, rendering them qualified for sizing applications. Regarding desizing, consumption of water and energy for removal of soy size could be remarkably decreased, comparing to removal of PVA. Moreover, with satisfactory degradability, the wastewater containing soy sizes was readily dischargeable after treated in activated sludge for two days. In summary, the fully biodegradable soy sizes had potential to substitute PVA for sustainable textile processing.
