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.

A kind of low molecular weight of chitosan was modified to water-soluble chitosan quaternary ammonium salt (short for HTCC) in this paper, where after, the Bombyx mori silk fiber and fabric were both treated by HTCC solution. The aggregation structure of silk fiber and the antibacterial performance and dyeing behavior of silk fabric treated by HTCC were investigated. The FT-IR and NMR results indicated that the substitution reaction mainly occurred on the amine groups of chitosan, and up to 90% substitution degree was obtained. Compared with chitosan, the solubility of HTCC was improved after modification. In addition, the crystallinity and the thermodynamic stability of silk fiber were improved after treated by HTCC solution, and the decomposition temperature increased from 318.93°C to 326.45°C. The antibacterial performance of silk fabrics to coli and staphylococcus were both significantly improved after treated by HTCC，and the inhibitory rate of silk fabrics had no significant decrease even though after soaping 30 times. Furthermore, the dyeing behaviors of silk fabrics to acid dyes and reactive dyes were improved, and the dyeing rate, the color fixing rate and the K/S value also increased.

In recent years, chitosan/inorganic composites have attracted increasing attention due to its fascinating properties and potential applications in biodegradable materials, drug release, electrochemical sensor, packaging materials and so on. Chitosan/inorganic composites are expected to be as an effective way to overcome shortcomings of slow flocculating speed of chitosan particles, not good enough to meet those wide range of applications in wasterwater treatment. In this study, novel chitosan/clay/PAC (polyaluminium chloride) composite was prepared, and it was used in treating effluent from dying and finishing process. One set of orthogonal experiments were conducted to optimize the experimental condition, and the results showed that removal of waste dye is affected by the dosage of chitosan, PAC, clay, pH and treatment time. The experiments results indicated that the effluent from dying and finishing process treated by the prepared composites became obviously fade, and its COD (chemical oxygen demand) decreased from original 1398.2mg/L to 197.6mg/L, the removing rate reached 85.9%.

2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (CS-12) is a non-water-soluble diol ester and an emerging green additive, widely used in paint industry. It can be synthesized by isobutyraldehyde with alkali as catalyst. In this article, several catalysts were studied for the synthesis of CS-12, for example, sodium hydroxide, calcium hydroxide, the mixture of sodium hydroxide and calcium hydroxide, sodium methoxide, the solution of sodium methoxide and methanol, and sodium ethoxide. Sodium hydroxide was finally selected as the optimal catalyst for the reaction. The effect of the amount of catalyst, reaction temperature and reaction time on the reaction were investigated by orthogonal experiments. The final optimal conditions are as follows: the catalyst dosage is 2 %, the reaction temperature is 50 °C, the reaction time is 4h. Under these conditions, the conversion of isobutyraldehyde is 93.10%, the selectivity of target product is 92.98%.

Antibacterial Performance

The water soluble photoinitiator (PI) 4-(trimethyl ammonium methyl) benzophenone chloride/UV system is used in the synthesis of silver nanoparticles (AgNPs). Green synthesis method involved using PI/UV system, carboxymethyl starch (CMS), silver nitrate, and water. AgNPs obtained had a spherical shape morphology and a size of 1–7 nm. To impart antibacterial properties, wool and acrylic fabrics were treated with AgNPs obtained. The PI/UV system was further utilized to fix AgNPs onto wool and acrylic fabrics by photocrosslinking to impart durable antibacterial properties. The effect of irradiation time on the antibacterial performance before and after repeated washing cycles was studied. S. aureus (as G +ve) and E. coli (as G −ve) were used to estimate the antibacterial performance of the finished fabrics. The antibacterial performance was directly proportional to the irradiation time but inversely proportional to the number of washing cycles. However, after the 15th washing cycle, samples still have bacteriostatic effect; that is, although they show zero inhibition zone, they cannot be attacked by the bacterial growth and do not inhibit the bacterial growth. AgNPs finished wool fabrics showed more antibacterial activity than those of AgNPs finished acrylic fabrics.
