Cotton fabrics were treated with different crosslinking agents under conditions found to be most favorable for chemiscrption of crosslinking molecules on cotton fibers. The effects of various factors such as period of chemisorption, temperature of drying and curing, concentration of crosslinking agents, pH, and nature of the catalysts on the physical properties of fabrics were investigated. The results show that chemisorption for a period of one hour is sufficient. Drying alone produces inferior properties of the fabrics compared to the fabrics which have been dried and cured. The results also indicate that the physical properties of the treated fabrics in the presence of sodium chloride are better than those obtained in the presence of magnesium chloride.

Abstract Since the discovery by Goodyear in 1839 that the physical properties of rubber may be improved with sulfur, it has been the most commonly used crosslinking agent. The rubber industry is concerned with the production of homogeneous products with appropriate physical properties, by compounding rubber with ingredients, including crosslinking agents, followed by processing, molding, and introduction of chemical bonds. Economically, it is advantageous to apply high temperature which reduces processing and curing time. However, application of high temperatures frequently causes premature cure. Compounding adjustments are often required in the plants to prevent scorch, especially by the use of compounds with S—N bonds as accelerators, vulcanizing agents, and also as prevulcanization inhibitors or retarders which delay the crosslinking reaction of sulfur and rubber. There are several reviews relating to accelerators, retarders, and vulcanization, which discuss S—N compounds as delayed action curing agents. This review covers the development of S—N compounds as delayed action chemicals for vulcanizing rubber, the various structural types, properties, applications, and the mechanism of their function during vulcanization.

To study the effect of active functional groups of cross-linking agents on the physical properties of starch polymer films. Standardized methods for studying the indicators of physical properties of polymer films have been applied. The paper presents the results of the study of the effect of crosslinking agents of different chemical structure on the physicomechanical properties, the influence of atmospheric moisture and the resistance to wet treatments of starch polymer films. An improvement in studied parameters of the films with the use of L-tartaric acid was established. It has been proved that the use of L-tartaric acid as a crosslinking agent makes it possible to improve the physical properties of polymer films based on starch. The obtained experimental results are of practical importance for the development of new environmentally friendly polymer materials.

The effect of different stitch combinations, namely, knit, tuck and miss stitches, on some of the physical properties of single jersey derivative fabrics have been studied. Fabrics which are in common commercial use in the textile industry were selected, and they are used as clothing fabrics. Knitted fabrics from 100% cotton yarn of 19.67 Tex on circular knitting machines were used in the study. The effect of knit structure on areal density, fabric thickness, air permeability, drape ability, stretch and recovery, shrinkage, and low-stress mechanical properties are investigated, and it was found that these properties are significantly affected by loop shape or knit structure, even though other knitting parameters remained the same. It was also found that the presence of tuck and float stitches for a given structure have a significant effect on fabric drape ability, width-wise extensibility, length-wise shrinkage, thickness, areal density and low-stress mechanical properties.

This study establishes an eco-friendly anti-wrinkle treating process for cotton fabric. Sodium hydroxide-liquid ammonia pretreatment followed by 6% (w/w) PU100 adding citric acid pad-cure-dry finishing. In this process, citric acid (CA) was used as the fundamental crosslinking agent during finishing because it is a non-formaldehyde based, cost-effective and well wrinkle resistance agent. Environmental-friendly waterborne polyurethane (WPU) was used as an additive to add to the CA finishing solution. Six commercial WPUs were systematically investigated. Fabric properties like wrinkle resistance, tensile strength retention, whiteness, durable press, softness, and wettability were well investigated. Fourier transform infrared spectra and X-ray diffraction spectra were also measured and discussed before and after adding waterborne polyurethane. Tentative mechanism of the interaction among the WPU, CA, and modified cotton fabrics is provided. The effect of cotton fabric pretreatment on fabric performance was also investigated. After the eco-process’s treatment, the fabric wrinkle resistant angle was upgraded to 271 ± 7°, tensile strength retention was maintained at 66.77% ± 3.50% and CIE whiteness was elevated to 52.13 ± 3.21, which are much better than the traditional CA anti-wrinkle finishing based on mercerized cotton fabrics. This study provides useful information for textile researchers and engineers.

This work introduces a series of vinyl-imidazolium-based polyelectrolyte composites, which were structurally modified via impregnation with multivalent imidazolium-benzene ionic liquids (ILs) or crosslinked with novel cationic crosslinkers which possess internal imidazolium cations and vinylimidazolium cations at the periphery. A set of eight [C4vim][Tf2N]-based membranes were prepared via UV-initiated free radical polymerization, including four composites containing di-, tri-, tetra-, and hexa-imidazolium benzene ILs and four crosslinked derivatives which utilized tri- and tetra- vinylimidazolium benzene crosslinking agents. Structural and functional characterizations were performed, and pure gas permeation data were collected to better understand the effects of “free” ILs dispersed in the polymeric matrix versus integrated ionic crosslinks on the transport behaviors of these thin films. These imidazolium PIL:IL composites exhibited moderately high CO2 permeabilities (~20–40 Barrer), a 4–7× increase relative to corresponding neat PIL, with excellent selectivities against N2 or CH4. The addition of imidazolium-benzene fillers with increased imidazolium content were shown to correspondingly enhance CO2 solubility (di- < tri- < tetra- < hexa-), with the [C4vim][Tf2N]: [Hexa(Im+)Benz ][Tf2N] composite showing the highest CO2 permeability (PCO2 = 38.4 Barrer), while maintaining modest selectivities (αCO2/CH4 = 20.2, αCO2/N2 = 23.6). Additionally, these metrics were similarly improved with the integration of more ionic content bonded to the polymeric matrix; increased PCO2 with increased wt% of the tri- and tetra-vinylimidazolium benzene crosslinking agent was observed. This study demonstrates the intriguing interactions and effects of ionic additives or crosslinkers within a PIL matrix, revealing the potential for the tuning of the properties and transport behaviors of ionic polymers using ionic liquid-inspired small molecules.

Coating of nanoparticles on fabrics provides huge potential applications in textile industry. The microencapsulation process is used to encapsulate the nanosilica particles which is used to coat on the surface of fabrics and to observe the special properties such as anti-bacterial, wrinkle resistance, etc. The amorphous nano silica particles were prepared from the natural resources through chemical route. The encapsulated nano silica was prepared using sodium alginate as a wall material by the coacervation method. The prepared sample was coated on the surface of the fabrics by pad-dry-cure method. The anti-bacterial studies were carried out for the nano silica coated and uncoated fabrics and the results would demonstrate the antibacterial effectiveness of treated cotton fabrics. The basic properties like tensile strength, tear strength, air permeability, crease recovery and whiteness index have been analysed for the coated and uncoated fabrics.
