This work presents synthesis and characterization of copolymer obtained by grafting acrylic acid on hydrolyzed potato starch in the presence various initiators (azobisisobutyronitrile, potassium persulfate benzoyl peroxide). Starch hydrolysis was made to reduce average molar mass, i.e. macromolecule size. Grafting monomer performed produce a product that can be used textile treatment, for example, yarn sizing. Various were used, primarily, graft polymer obtain thinner or thicker packaging...

The use of synthesized natural starches for the sizing process in fabric production is primarily an environmental contribution. Synthesized corn starch environmentally friendly and productive, showing good results cotton yarn sizing. Acrylamide (AA) 2-hydroxyethyl methacrylate (HEMA) were applied grafting starch, initiators azobisisobutyronitrile (AIBN), potassium persulfate (KPS), benzoyl peroxide (BP) chosen to form grafted monomers more effectively. application has been confirmed,...

This paper presents a detailed exploration of the development and characterization multifunctional dual-purpose woven fabrics for thermal protective clothing.

The analysis led to identification two optimal samples, which, upon further testing, exhibited exceptional...

Synthesis and characterization of copolymer obtained by grafting acrylamide onto hydrolyzed potato starch its application in cotton yarn sizing were presented this work. Some process parameters hydrolysis grafting, like as yield, percentage, graft efficiency, monomer to polymer conversion determinated. Molar mass values samples are located a narrow range 1 × 105 107 102 104. Grafted starch, agent, gives better results than nongrafted, particularly terms uniformity, mechanical parameters,...

The role of automotive textile materials is great importance and therefore this paper analyses the properties such – airbag fabrics upholstery fabrics. Fundamental characteristics construction parameters artificial leather with bonded fabric on back side, as well joining (sewing) quality places cut parts are crucial for durability, comfort aesthetics interior design, were analysed. Airbag specificity extreme values several achieved by manufacturing process, extremely high densities in warp...

In this paper, the synthesis, characterization and application of a copolymer as sizing agent obtained by grafting methacrylic acid on hydrolyzed potato starch were investigated. Starch hydrolysis was performed in order to reduce average molar mass (i.e. size macromolecules). Grafting obtain product that can be effective textile processing, for example, yarn. The monomer has been confirmed Fourier transform infrared spectroscopy spectra grafted starch. distribution masses determined...

The objective of this research was to verify the feasibility use newly synthesized biopolymer materials for sizing cotton yarns based on basic principles chemical modification. Research included acid hydrolysis potato starch up controlled molar masses together with graft-polymerization and methacrylic onto hydrolyzed improve hydrophilicity solubility, increase capability film forming, adhesive potential avoid retrogradation phenomena. objectives were primarily focused finding an appropriate,...

The paper describes our research of microwave usage in drying the size pick-up. An analysis three different processes relation to physical-mechanical properties sized yarn has been carried out. Under same sizing conditions, but methods, following parameters were determined: breaking force, elongation at break, abrasion resistance and hairiness. application method for warp showed be equally good, or even better some cases, compared conduct convection methods.

Among many other materials for the reinforcement of composites, technical fabrics are increasingly being used same purpose, especially from glass and basalt tows, which have good mechanical properties.. During tensile stress these elongated in direction force, at time they contract crosswise relation to action force. In this paper properties woven made yarns were investigated. Measurements focused on lateral contraction, according Poisson’s ratio can be calculated. For purposes, an...

Determination of Poisson’s ratio and shear module complex, nonlinear elastic material, such as woven fabric, is a challenge for researchers in the field textile mechanics. In standard method determining ratio, transverse fabric strain measured by 1% tensile extension. this way, there no information about changing at higher extensions, methodology itself unsuitable larger extensions because buckling. research, device has been designed, which can be built on dynamometer ability to measure...

The subject of the paper focuses on effect weave architecture microbial barrier properties woven fabrics or more precisely identifying crucial elements that dominantly influence bacteria penetration in dry condition. For purpose, 12 samples cotton were and examined. In their structure, all had same yarns (36 tex) warp weft, densities (24 yarns/cm), two weft 20 yarns/cm) six different basic structures. Microbial permeability was determined according to a previously developed test method...

The purpose of this paper is to show the degree changes in mechanical and deformation properties single cotton yarn after sizing depending on their fineness, size concentration structure created by type spinning. ring rotor-spun yarns were analyzed before with a PVA agent, using same recipe, but two different concentrations — 7.5% 5.0%. Standardized methods for determining used, as well modified method cyclic testing determine areas elastic, viscoelastic plastic deformations. There are no...

In this work, aramid fibers were used to develop new, high-performance fabrics for high-temperature protective clothing.

The breaking force of warp yarns taken per segments on the loom is measured using three weaves from same different looms. To simulate deformation yarns, samples beam are and, after various conditions cyclic stress a dynamometer, most approximate degree that which occurs in weaving process and weave types. F-test, t-test, χ 2 -test, correlation coefficient reveal there no differences among values looms or relaxation meaning imparted to during very similar. Deformation caused by friction metal...
