A novel poly(4-iodobutoxylmethylsiloxane) (PIBMS) water repellent with high reaction activity was synthesized using poly(hydromethylsiloxane) (PHMS), methyl iodide (MeI) and tetrahydrofuran (THF) in the presence of a catalytic amount of PdCl2. The new chemical active group of PIBMS could covalently bond to the cotton fabric. It is conducive to improve the washability of treated cotton fabric. The structure of PIBMS was confirmed by the FT-IR and 1H NMR spectra. The PIBMS was applied onto cotton fabric by a pad-dry-cure process. PIBMS was applied to cotton fabrics and the effect of the process parameters on water repellent performance was studied. The morphology of PIBMS polymer film on the cotton fabric was investigated by SEM. The water repellency of treated cotton fabrics before and after vigorous washes was compared. The results show that the water repellent grade of cotton fabric treated with PIBMS was 90. The contact angle of the treated cotton fabric was 136.94°, which was higher than that of the untreated cotton fabric. The water repellent grade of treated cotton fabric was still as high as 80 after 20 times washing. The tear strength and the tensile strength of cotton fabric significantly increased after PIBMS treatment. The air permeability and the water vapor permeability of treated cotton fabric were slightly lower than those of untreated cotton fabrics.

BiOCl nanosheets were prepared through a simple solvothermal method. The obtained BiOCl nanosheets were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and UV spectroscopy. The average size of BiOCl nanosheets was 210[Formula: see text]nm. The BiOCl nanosheets were applied as a finishing agent for cotton fabric, which can give the UV protection and photocatalytic degradation of RhB properties to cotton fabric. We made four different concentrations of finishing agents to coat the fabric by pad-dry-cure method. Furthermore, the UPF ratting and photocatalytic degradation of RhB were conducted. The finished cotton fabric exhibited excellent UV protection and photocatalytic property.

Inducing multifunctionality is the need of the products used in diverse environments. Here, polyurethane-based water repellent, flame retardant and antibacterial coatings are fabricated on cotton fabrics which sequentially involve the deposition of coating through knife coating, drying and curing of coated fabric. Taguchi design has been used to optimize the parameters for enhanced water repellency, flame retardancy and antibacterial activity. When applied individually, the performance characteristics enhance with the increase in concentration of respective finishing agent. However, a different behaviour was shown by the coated fabric when applied all the finishing agents simultaneously. Taguchi design enabled the monitoring of interdependency of different concentrations of chemicals and finding the most influencing parameters for efficient performance of coated fabrics.

In this paper, a super-hydrophobic cotton fabric was fabricated by low-pressure plasma-enhanced chemical vapor enhanced deposition (LP-PECVD) with lauryl methacrylate (LMA) as the functional monomer. Scanning electron microscopy (SEM), atomic force microscope (AFM) and X-ray photoelectron spectroscopy were used to analyze the changes of surface morphology and chemical composition of the cotton fabrics surface, respectively. A randomly wrinkled morphology was exhibited by SEM and AFM. The combination of the low surface energy film of LMA and micro-nano-scale structure resulted in the super-hydrophobicity of modified cotton fabrics. The reactive species in LMA/Ar plasma were studied by optical emission spectroscopy, and based on the results of the test, the reaction principle in the plasma reaction chamber was discussed. It was proved that the LMA film is polymerized by chemical bonds on the surface of cotton fibers. The water repellency, washing stability, water-vapor transmission, air permeability and tensile property of fabrics were also discussed. We found that a washing-stable and breathable super-hydrophobic cotton fabric can be achieved after treatment without decreasing the tensile property.

A new finish for cotton fabric which imparts high oil repellency with low water repellency is described. The finish is based on the reaction of tetrakis(hydroxymethyl)-phosphonium chloride and 1,1-dihydroperfluorooctylamine and is applied from aqueous emulsions with a gaseous ammonia cure. The emulsion is suitable for simultaneous application with a typical permanent-press agent to obtain wrinkle-recovery properties. In soiling tests, certain of the soiling properties of the finish showed an improvement over commercially used fluorocarbon treatments in the range of add-ons studied.

An attempt has been made to develop multifunctional cotton fabric, possessing water repellent, stain repellent, shrink resistance and quick dry properties using fluorocarbon resin. The hydrophobicity of cotton fabric was determined by carrying out water repellency test, taking scanning electron microscopic photographs and measuring water contact angle. The durability of hydrophobicity of cotton was tested till 20 washes and found satisfactory. Oil repellency was determined employing hydrocarbons resistance test. The air permeability of cotton fabric was also determined keeping in view the impact on breathability of treated cotton and was found quite good. The untreated and treated cotton fabric was subjected to repeated domestic laundry condition, and shrinkage was measured, which indicated excellent shrink resistance behaviour because of its water repelling characteristic. This hydrophobicity of cotton also added to its quick dry behaviour even at low temperature and high relative humidity. The physical properties of treated dyed cotton fabric samples were compared with untreated, and no significant changes were observed in colour fastness to washing, rubbing, perspiration and light. The tensile and tear strength showed good retention even at higher concentration of fluorocarbon resin. This work is of great industrial importance for textile products used in home textiles. The textile industry can fetch more export earnings by doing multiple value addition using the same chemical. The work reported in the literature is about using fluorocarbon and developing water- and oil-repellent fabrics. In the present work, apart from water and oil repellency, shrink resistance and quick dry behaviour of cotton textile has also been established using same fluorocarbon because of hydrophobicity imparted to cotton.

Water repellent is an important functional finish for cotton fabric. However, cotton fabrics often have poor washing resistance and other performances after actual finishing. In this study, based on the structural characteristics of cotton fiber and durability of water repellent, a cross-linked amino long-chain alkyl polysiloxane (CAHPS) was first prepared, and then reacted with modified silica. Finally, a chemically bonded organic–inorganic nanohybrid cross-linked polysiloxane (rSiO2-CAHPS) was fabricated. Furthermore, the rSiO2-CAHPS was emulsified to obtain a durable fluorine-free water repellent. The water repellent finishing for cotton fabric was carried out by the pad–dry–cure process. After finishing, the cotton fabric had good resistance to conventional liquids and excellent washing resistance, and still maintained good water repellency after 30 rounds of soaping. Moreover, properties including air permeability, mechanical property and whiteness are hardly affected after finishing. SEM and XPS characterization show that a layer of dense silicon film is formed on the surface of cotton fabric by rSiO2-CAHPS water repellent. The existence of nanosilica can improve the surface roughness of cotton fibers. The synergistic effect of fiber matrix, nanoparticles and CAHPS endows the fabric with a micro/nano-multi-scale micro-rough structure, which improves the water repellency of cotton fabric after water repellent finishing.

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.
