Inexpensive and biodegradable thermoplastics were developed through graft polymerization of native chicken feather with methyl acrylate as a potential substitute for petroleum products. Poultry feathers are available in large quantities at low price. However, natural have poor thermoplasticity, cannot be used to develop thermoplastic products, very limited industrial applications, often considered solid wastes. In this research, the effects conditions, such molar ratio NaHSO3 K2S2O8,...

As an important high-tech anti-counterfeiting material, fluorescent fiber has attracted great interest from researchers in the textile field. In order to endow chitosan (CS) with good fluorescence for preparation of fibers, various amounts molecules—perylene tetracarboxylic acid (PTCA)–were used label CS prepare a series CS-perylene different degrees labeling (DL). Then, nanofiber membranes were produced by electrospinning using CS/PVA blend spinning solutions. The effects DL on application...

Abstract Starch was pretreated with allyl etherification to enhance the grafting efficiency of copolymerization granular starch acrylic acid and improve properties starch‐ g ‐poly(acrylic acid) used as a warp sizing agent. The graft carried out in an aqueous dispersion ferrous ammonium sulfate hydrogen peroxide initiators. Through introduction groups into before copolymerization, could evidently be enhanced, such fiber adhesion film behaviors copolymer were improved. pretreatment capable...

Camelina meal contains oil, proteins, and carbohydrates that can be used to develop value-added bioproducts. In addition containing valuable polymers, coproducts generated during the production of biofuels are inexpensive renewable. is a preferred oilseed crop for biodiesel because camelina easier grow provides better yields. this research, components in were extracted studied their composition, structure, properties. The potential using thermoplastics was also by grafting various vinyl...

In this paper, an attempt has been made to ameliorate the adhesion of starch polyester fibers for warp sizing. The amelioration was achieved by blending newly developed water‐soluble aliphatic–aromatic copolyester (WSACP) in because copolymer had proved possess better biodegradability than pure aromatic polyester. focused on determination molar ratio aliphatic units incorporated into WSACP, amount WSACP blended, and analysis experimental observations from viewpoints theory. evaluated terms...

The adhesion of water‐soluble polyester (WSP) sizes to fibers was investigated reveal the relation between functions glycol and benzenedicarboxylate units in WSP macromolecules order improve performance warp sizing. Serial WSPs with variation both structures were synthesized through a two‐step reaction: transesterification polycondensation. evaluated terms tensile strength work‐to‐break using slightly sized roving method. depended markedly on units. decrease length unit enhanced adhesion....

In order to study the effects of molecular structure aliphatic dicarboxylic ester (ADE) monomers on sizing properties and biodegradability water-soluble polyester (WSP), pure aromatic WSP aliphatic–aromatic copolyesters with different using ADE various carbon chain lengths were prepared through transesterification–polycondensation. Then, evaluated in terms viscosity weight, apparent viscosity, stability, crystallinity, adhesion fibers, tensile film, CODcr, BOD5. It was found that decrease...

Biodegradable and inexpensive sizing agents were developed through graft polymerization of native feather keratin with acrylic acid (AA). Feathers are available in large quantities at low price more than 80% them keratin. However, poor water solubility under neutral condition greatly limits the use as warp sizes textile industry. In investigation, effects modification on properties studied terms solubility, apparent viscosity, adhesion to fibers. It was found that grafting appropriate...

In order to solve such utilization problems as excessively high apparent viscosity of sizing paste and poor adhesion polyester fibers, caused by macromolecular inherent defects native sesbania gum (SG), various amounts methyl acrylate (MA) monomers were grafted onto molecular chains SG through initiation Fenton's reagent a series SG-g-PMA with different grafting ratios prepared. Effects the graft modification on properties studied in terms viscosity, contact angle water-solubility,...

The aerobic biodegradability of acrylate copolymers for warp sizing was studied using the shaking-bottle incubating method their COD removal rates after being cultivated 30 days. Influences unit chemical structure, including alkyl chain length ester group, α-methyl and molar content units, on sizes were investigated. prepared via free radical copolymerization acrylates with acrylic acid in ethanol. strongly depended structure units. After days, poly(MA-co-AA) biodegraded substantially rate...

In order to endow feather keratin with good sizing properties for all-polyester or high-polyester yarns, methyl acrylate (MA) and acrylic acid (AA) monomers a variation in feed molar ratio from 10/90 30/70 were grafted onto the molecular chains of native under equal monomer concentration. Effects compatibility MA/AA on keratin-g-P(AA-co-MA) studied terms apparent viscosity, contact angle paste polyester fibers, mechanical film, adhesion fibers. It was found that grafting MA & AA rational an...

In order to impart good application performance locust bean gum (LBG) sizes for polyester yarns, methyl acrylate (MA) and acrylic acid (AA) monomers with a variation in feed molar ratio from 1/9 4/6 were grafted onto the molecular chains of native LBG obtain LBG-g-P(MA-co-AA) products similar grafting ratios through Fenton redox system.
