A new reactive water-soluble isothiazolinone antibacterial was synthesized and characterized by 1H-NMR and ESI-MS. Through the orthogonal experiments, the optimal finishing process for cotton fabric was got, that was the bath ratio 1:20, Na2SO4 20 g/L, NaHCO3 15 g/L, t1: 30 min, t2: 50 min, T1: 50oC, T2: 95oC. The antibacterial evaluations of treated cotton fabrics showed that the antibacterial rate for S. aureus was 92.92%, and 86.04% after 50 washing cycles. The results indicated that the treated fabric had excellent antibacterial performance and washing durability.

A new antibacterial with two reactive groups was synthesized from isothiazolin-3-one and characterized by 1H-NMR and ESI-MS. Through the orthogonal experiments the optimal finishing process was got, that was bath ratio 1:20, Na2SO4 20 g/L, NaHCO315 g/L, T1:60°C, T2:70°C, t1:10 min, t2:20 min, t3:30 min (as shown in fig.1). The antibacterial evaluations of treated cotton fabrics showed that the antibacterial rates for Escherichia coli and Staphyloccocus aureus were 95.64% and 97.83% respectively, and 88.13% and 90.05% respectively after 30 washing cycles.

Two reactive antibacterials were applied to finish for polyester/cotton (T/C) blend fabrics (20/80) and (35/65) and the optimal finishing process was obtained by orthogonal experiments. The finished fabrics were undergone the evaluation of antibacterial performance. For both of the two antibacterials and two T/C fabrics, the lowest inhibition rates for Staphyloccocus aureus were 85.97% and 79.19% after 50 washing cycles. The results indicated that the treated fabric had good antibacterial performance and washing durability.

The popular use of silver nanoparticles (Ag NPs) in commercial textile products that inhibit odor- and/or infection-causing bacteria has continuously raised concerns about their washing durability. The poor durability not only deteriorates the antibacterial performance, but also results in unwanted leaching of NPs into washing solutions. In this study, we showed how the incorporation location of Ag NPs—interior vs. exterior of cotton fiber—governs their durability against consecutive simulated home launderings. The superior washing durability of interior NPs was confirmed. The Ag losses after 50 laundering cycles for interior and exterior systems were 16% and 63% in water and 24% and 78% in detergent solution, respectively. The cotton fabric containing interior NPs predominantly released ionic Ag, whereas the fabric containing exterior NPs released particulate Ag.

Cotton fabric is commonly used in daily life, but it is easily wetted and contaminated by liquid. Herein, we present a simple and environmentally friendly plasma technology for hydrophobic modification of cotton fabric. In order to endow superhydrophobicity to cotton fabric, helium plasma inducing graft polymerization of 1,3,5,7-tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane (D4Vi) was utilized to wrap SiO2 particles on cotton fabrics. Cotton fabrics were successively dipped in silica sol and D4Vi, then treated by plasma. Cotton fabrics before and after modification were characterized by using field emission scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and water contact angle measurement. The experimental results showed that the cotton-SiO2-D4Vi consisted of nanoscale SiO2 protrusions and low-surface-energy film polymerized by D4Vi. In addition, the one wrapped SiO2 of 161 nm presented excellent hydrophobicity, washing durability, and repellency toward different types of liquids with a water contact angle of 152°.

A series of modified nanoTiO2 photocatalysts, nanoPC, was applied to cotton fabrics through a pad-dry-cure process. The effect of nanoPC dosage, the ratio of nanoPC to crosslinking agent, and curing conditions on the degradation of formaldehyde were discussed. The optimal finishing process of cotton fabric with nanoPC was determined as follows: 1%~1.5% photocatalyst, curing at 130°C for 5 minutes. Cotton fabric treated with the above process demonstrated over 90% degradation of formaldehyde, good washing fastness and soft handle, as well as little loss in breaking strength, tearing strength and polymerization degree.

A superhydrophobic complex coating for cotton fabrics based on silica nanoparticles and new fluoroalkylsiloxane polymer was reported here. The complex thin film was prepared through sol-gel method using cotton fabrics as a substrate. Silica nanoparticles in the coating made the textile surface much rougher, and new fluoroalkylsiloxane polymer with reactive groups on the top layer of the surface lowered the surface free energy and enhanced the binding between silica nanoparticles and the fluoro-containing polymer. Textiles coated with this coating showed excellent water repellent property, and water contact angle (CA) increased from 138° on the pure fluoroalkylsiloxane polymer treated cotton fabric up to 156.5° on complex one. Moreover, this superhydrophobic complex coating possesses favorable washing durability and its CA still retain 106° after 20 times of soaping operations.

Silver nanoparticles which are highly effective in killing bacteria have been applied in many fields. One of its practical applications is that the silver nanopartcles are applied in textiles for creating antibacterial fabric. In this work, the cotton fabrics were immersed in nano silver colloid (diameter = 7-11 nm) which is prepared by polyol process with microwave heating. The antibacterial performance of the antibacterial cotton fabric was tested for different concentration of nano silver colloid, contact time germs, and washing time. It was found that antibacterial activity increased with the increasing concentration of nano silver colloid, contact time germs and with the decreasing washing time.

Crosslinking of cellulose is considered a necessary process in creating anti-wrinkling cotton fabrics. In the recent years, the concern of buyers regarding the wrinkle-resistant fabric has increased the demand of easy-care finishes. Formaldehyde based easy care finishes are carcinogenic but still used in the textile industry. Low formaldehyde reagents are being developed and tested to replace formaldehyde based easy care finishes. In this research the low formaldehyde easy care finishes; Fixapret ECO and Alkaknit WFR were investigated for their effect on color fastness to crocking, tear strength, tensile strength and durable press rating. Findings of the research showed that the there was a subsequent decrease in tensile and tear strength as compared to original fabric with the increase in resin concentration on both type of dyes. From the results we can say that higher the resin concentration, better the washing durability. This is due to the fact that resin decreases the chance of fiber chain displacement. The fabric with navy blue dye displayed much better performance and compatibility with non-formaldehyde resins as compared to turquoise blue dye.

Superhydrophobic cotton fabrics have been widely explored for their excellent properties, although there are still a few limitations in the practical applications for the reasons of poor environmental performance and short service life. In this study, the hexadecyltrimethoxysilane emulsion was prepared using O2-plasma and ultrasound for the superhydrophobic functional finishing of raw cotton fabric by immersion method. The prepared cotton fabrics showed a superior hydrophobicity with water contact angles larger than 156.0°, as well as an excellent self-healing ability. This self-healing ability was gained by simple heating treatment, which could restore the superhydrophobicity of the hydrophilic cotton fabric damaged by abrasion or O2-plasma treatment. The superhydrophobic cotton fabrics demonstrated excellent washing durability, which can withstand 50 times accelerated laundering cycles. Besides this, the superhydrophobic coatings also displayed fair chemical stability in strong acidic and alkaline solutions. The prepared nonfluorinated superhydrophobic cotton fabric with self-healing ability shows a potential for practical functional textile application.

A series of novel fire-retardant agents, fluorocyclotriphosphazene derivatives with the substitution groups of 2,2,3,3-tetrafluoropropoxy groups were synthesized using hexachlorocyclotriphosphazene and 2,2,3,3-tetrafluoropropyl alcohol as starting materials. The synthesized fire-retardant agent was emulsified and applied on the cotton fabric finishing to reduce the flammability and afford water/oil repellency simultaneously. The optimum finishing process was achieved according to the test of cotton finishing with fluorocyclotriphosphazene. The treated cotton showed not only excellent fire-retardant performance, but also water and oil repellency with little change in strength and whiteness.
