“…Nevertheless, common modified starches fall short of sizing performances with respect to mechanical properties, fiber adhesion and water sensitivity of the films 7. To overcome these shortcomings, more attention was paid to physical modification of starch sizes with environmental‐friendly small molecules 7 and water‐soluble polymers 8, and introduction of inorganic nanoparticles into starchy materials 6, with the purpose of changing the supramolecular structures of starches.…”

Na-montmorillonite (Na-MMT) was ball-milled, and a starch/MMT nanocomposite for warp sizing was prepared by solution intercalating technique, with oxidized corn starch (OS) of concentration 6 wt% and the Na-MMT of 5 wt% on the basis of dry OS. Scanning electron microscope and laser particle size analyzer were used to investigate the particle morphology and size distribution of the MMT. The interlamellar spacing of the MMT and crystal structure the OS-based composite film were analyzed by using XRD. The sizing performances of the nanocomposite were also tested. All of the experiments conducted, together with those of the OS alone and OS/unmilled MMT for comparison. The results revealed that the ball-milling treatment resulted in a smaller partical size with a narrow distribution, and larger interlamellar spacing of the Na-MMT. In comparison with the pristine clay, the milled MMT restrained the crystallization of OS to a greater extent as composited into the OS, had more decrease effects on apparent viscosity of OS paste and hygroscopicity of the casting films, and had more improvement effects on the tensile properties of OS films and adhesiveness of sizes to fibers.

In this study, an oxidized starch (OS)/montmorillonite (MMT) nanocomposite was prepared via a solution intercalation method. Before incorporating MMT into OS, MMT was organically modified with 20 wt% of octadecyl dimethyl tertiary amine followed by a hydrophilic ball‐milling treatment in the presence of urea, ethanol, and formaldehyde (two‐step processing technique). X‐ray diffraction revealed that the interlayer spacing of the MMT expanded from 1.29 to 2.00 nm after the organic modification and MMT turned into an exfoliated state after the hydrophilic treatment and the solution intercalation, which was also confirmed by transmission electron microscope result. Owing to the interaction between OS and the silicate layers, the hygroscopicity of the obtained nanocomposite decreased and the mechanical properties were improved. Our work demonstrates that the two‐step processing technique is a promising method for modifying MMT nanofillers and preparing starch/MMT nanocomposites, which paves a way for preparing other polar polymer‐based nanocomposites and developing environment‐friendly textile sizing materials.

“…For instance, native (unmodified) starch solutions have poor viscosity stability and it is difficult to desize (remove size) fabrics containing starch. Starch films formed on the surface of fibers are considerably brittle and therefore the starch-sized materials are not easily processable at low humidity levels (Liu et al 2010). Further, fabrics sized with starch are mostly desized using enzymes and/or acid or alkaline hydrolysis at high temperatures (80-90 °C).…”

Two plant proteins, soyprotein and wheat gluten, and chicken feathers used to size cotton substrates provided sizing performance similar to starch and were also easily degraded in activated sludge. Sizing is an essential process to impart protection to warp yarns and increase weaving efficiency. Cotton yarns have traditionally been sized with starch, modified starch derivatives, CMC, poly vinyl alcohol (PVA), or a combination thereof along with quite a few other fiber binding ingredients. Although starch and starch derivatives are extensively used for sizing, there can be several limitations including less-than-satisfactory sizing performance and difficulties in desizing starch based size. Plant proteins such as wheat gluten, soyproteins and poultry feathers are available in large quantities at low cost and have limited industrial applications. However, these proteins are known to have excellent film-forming properties, a primary requirement for a warp size, and have also been used as adhesives. Using proteins as warp sizing agents on cotton yarns potentially could provide acceptable sizing performance and be cost-effective, as well. In this research, soypro-teins, wheat gluten, and chicken feathers were studied for exploring their feasibility for sizing, desizing, biodegradability, and ability to replace starch and PVA for sizing cotton yarns. It was found that all three proteins provided similar cohesion to fibers and abrasion resistance compared to starch. Protein sizes had significantly high BOD 5 /COD ratio compared to PVA, suggesting that the proteins are easily degradable in textile effluent treatment plants.
