Oil Repellent

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.

The Impact

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.

Nowadays, the methods and techniques used in the textile industry are required to be environmentally friendly, and water and energy saving. In addition to these, they should transfer more than one functionality, in other words give multifunctionality to the textile material with reliable and sufficient results in terms of efficiency and permanence. With the increase in and diversification of today's industrial requirements, one functionality on the fabric may be insufficient to meet the requirements, and therefore the subject of multifunctionality holds an important place in the textile industry. Therefore, in this study flame retardant, antibacterial and water-repellent, single-layered multifunctional 100% cotton fabrics with different functionalities on different sides (back and face surfaces) of the fabric were obtained via a chemical foam application method, which has many advantages compared with conventional methods. In some of the experimental parts, impregnation and foam application methods were combined in the process in order to optimize the multifunctionality properties of the fabrics. In order to indicate the performance test of cotton fabric, vertical burning test, contact angle test, antibacterial test against Gram positive and Gram negative bacteria, color spectrum analysis and tearing strength test were carried out while, in terms of characterization tests, Fourier transform infrared (attenuated total reflectance) and scanning electron microscope analyses were performed. According to the test results, the flame retardancy effect of the samples was improved significantly while antibacterial results showed a 99% reduction of bacteria and the finished fabrics demonstrated improved water repellency with contact angles up to 125°. In addition, the functionalities were durable up to 50 washing and 50 drying cycles.

In this work, cotton was grafted with trifluoroethyl methacrylate (TFEMA) via atom transfer radical polymerization (ATRP) in water aqueous. The appearance of the cotton fabric was characterized with SEM, and SEM of the grafted cotton displayed significant difference from the ungrafted cotton. FT-IR indicated that TFEMA was successfully grafted onto surface of cotton fibers. Surface contact angle test and water repellency rating test showed that the water repellence of the modified cotton fabric were better than the ungrafted cotton fabric. Compared with the ungrafted cotton fabric, the whiteness, air permeability, breaking strength and elongation at break of the grafted cotton fabric decreased slightly. Grafted treatment led to efficient implantation of fluorine atoms on the surface of cotton fabric, this resulted in water repellence without altering the bulk properties of the cotton fabric.

Copper salts were found to stabilize tetrakis (hydroxymethyl) phosphonium hydroxide (THPOH)-ammonium hydroxide solutions by formation of a complex thereby making it possible to apply THPOH to cotton fabric from a single bath without the use of gaseous ammonia. The effect of the concentration of copper salts, THPOH, and NH4OH on the stability of the solution was studied. Cotton fabric with good flame retardancy, strength retention, and hand was obtained by the use of conventional pad-cure techniques for applying the solutions. Cotton fabrics with approximately 17% add-ons retained their flame retardancy after 25 home launderings.

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.

AbstractHighly hydrophobic surfaces exhibit a remarkable feature in the repellency of oil and water. However, the relatively complex preparation process, high costs, and harmful compounds have largely limited their applications. This research aim is to fabricate hydrophobic nonwoven fabrics with low-cost and nontoxic materials. Despite various wettable materials, nonwoven cotton fabric material bearing hydrophobic surfaces has been received significant attention. This is mainly owing to its easy handling, high flexibility, environment friendly, low cost, biodegradability, high efficiency, and easily scalable fabrication. In this study, a simple chemical modification method using hexadecyltrimethoxysilane (HDTMS) with ethanol which is a better method in comparison with other methods since it is an inexpensive, simple method, and offers an easy adjustment of chemical composition required for a surface to show hydrophobic behaviors. The wetting behavior of cotton samples was investigated by water contact angle measurement. The best result comes from 2 ml HDTMS with 40 ml ethanol at 60 °C. The result shows that the treated cotton fabrics exhibited excellent chemical stability and outstanding non-wettability with the WCA of 126 ± 2°. It also shows that standard oil and water repellency, which offers an opportunity to accelerate the large-scale production of hydrophobic textile materials for new industrial applications.

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.
