“…For example, it is recommended to take into account data of dispersed phase particle size distribution when making reinforced composites with a graftcopolymer adhesive introduced into the pores of a textile substrate or when using functional nanodispersed fillers. [80][81][82][83][84][85] When modifying biopolymer and fibrous materials, the state of enzymatic preparations must be characterized based on the size distribution of the relative number of particles. 33,46,[86][87][88] The number of particles in these processes depends on the number of simultaneous catalytic events involving protein catalyst globules.…”

We propose the final softening finishing of textile products based on a complex of modifying effects on a highly ordered cellulose backbone of the secondary cell wall G-layer or on a mesh corset of microfibrillar cellulose in the primary cell wall. We suggest using polypeptide molecule sizes and the strength of polypeptide molecule adsorption binding on a model solid-phase substrate as parameters of the structurally regulated action of cellulase preparations. The article presents an analysis of 11 cellulase preparations as groups of weakly, tightly and medium adsorption enzymes, and also groups of volumetric, peripheral or combined activity manifested in the fiber structure. We show the regularities of enzyme property influence on the fiber pore structure development, changes in the parameters of the fabric bending stiffness and breaking load and technological shrinkage for two modification modes: liquid treatment with flax fiber swelling or low-modulus application solution. For the liquid method of treatment (with a bath module of at least 10) it is recommended to apply highly adsorbable cellulases ( A > 50%), in which the content of molecules with a globule size less than 30 nm does not exceed 15%. For the low-modulus method of treatment it is recommended to use enzymes with the adsorption capacity of at least 40% and a low content of small-sized fractions (no more than 25%). The recommended treatment variants ensure a three to four-fold bending stiffness decrease at the mechanical strength loss of not more than 15% and shrinkage of linen fabrics not more than 0.5%.

“…PET film as a packaging material does not fully fulfill the requirement of the oxygen barrier property [27,28]. Polymeric coating, which is characterized by a simple operation, low cost [29,30], diverse functionality [31,32], and benign adhesion [33], is promising for the functionalization of PET film. Currently, two types of polymer coatings have been mainly studied to promote the barrier capability of PET films: crystalline polymers and amorphous polymers [34,35].…”

Polymeric barrier materials are critical in contemporary industries for food, medicine, and chemical packaging. However, these materials, such as PET films, are impeded by the optimization of barrier properties by virtue of molecular design. Herein, a new methyl methacrylate-methyl acrylate-diallyl maleate-maleic acid (MMA-MAc-DAM-MA) was synthesized to tailor the surface properties of PET films for maximizing oxygen barrier properties. During the MMA-MAc-DAM-MA coating and curing process, the chemical structure evolutions of MMA-MAc-DAM-MA coatings were characterized, indicating that the cross-linking conversion and proportion of –COOH groups are critical for the oxygen barrier properties of coatings. The inherent –COOH groups are transformed into designed structures, including intramolecular anhydride, inter-chain anhydride and retained carboxylic acid. Therein, the inter-chain anhydride restraining the activity of coated polymer chain mainly contributes to enhanced barrier properties. The thermal properties of novel coatings were analyzed, revealing that the curing behavior is strongly dependent on the curing temperatures. The impacts of viscosity of the coating solution, coating velocity, and coating thickness on the oxygen permeability (Po2) of the coatings were investigated using a gas permeability tester to explore the optimum operating parameters during practical applications, which can reduce the Po2 of PET film by 47.8%. This work provides new insights on advanced coating materials for excellent barrier performance.

Kornilova and co-authors, in the article "Multifunctional polymer coatings of fusible interlinings for sewing products", use a popular method of dipping to obtain coatings [5]. The article "Properties of polypropylene yarns with a polytetrafluoroethylene coating containing stabilized magnetite particles" by N. Prorokova and S. Vavilova develops a new method of forming coatings based on the application of a coating-forming composition on the surface of a semi-cured thermoplastic filament at the stage of its melt spinning followed by orientational stretching [6].…”
