Using low temperature plasma for surface modification of polyester fabric: dyeing and printing improvement

Using plasma as a green and fast method for surface modification of textiles was considered by many researchers. In this study, polyester fabric was treated with cold plasma for different times between 1 and 5 min. Untreated and treated fabrics were bleached and dyed with jet and thermosol method and was printed with inkjet and silk screen method. The scanning electron microscope (SEM), FT-IR spectroscopy and X-Rite reflection spectrophotometer were used to analyze the results. The results show that despite the fact that the plasma treatment of polyester fabric results in a reduction in the whiteness of the fabric, it has a higher whiteness after the bleaching of the plasma treated fabric compared with the untreated fabric. The results also show that, plasma treatment causes increasing the color absorption in continuous and non-permanent dyeing methods. Also, it should be mentioned that, the increase of color absorption in the continuous method is appreciably higher than the non-continuous method. Moreover, plasma treatment increases the absorption of color in polyester printing. By increasing the time of plasma treatment, the color absorption increased. Under the same conditions of printing, the penetration and diffusion of the color in the plasma treated fabric is lower than the untreated one.

Modification of polyester fabrics with nanosized titanium dioxide to impart photoactivity

Modification of the polyester fabric using the diluted suspension of nanosized titanium dioxide is shown to make the fabric capable of decomposing the adsorbed contaminants under irradiation. The effect of different types of preactivation of polyester material on the self-cleaning ability of the fabrics is investigated. Chemical preactivation and preactivation using surface barrier discharge plasma additionally enhances the photochemical activity of the modified fabrics. The resistance of the achieved effect to operational impacts, such as washing and dry friction, is estimated and is found to be satisfactory. Modification of polyester fabrics using nanosized titanium dioxide protects it against intense UV radiation.

Study on the novel Modification of Polyester Fabrics with Sericin Protein

To improve the hydrophobicity and antistatic property of polyester fabric, A novel sericin modifier was prepared by amino in the sericin reacting with epichlorohydrin in alkaline condition under the protection of N2. And then it was grafted onto the polyester fabric treated alkaline deweighting. The optimal technological conditions of sericin modifier were achieved through orthogonal design experiment. The polyester fabric treated with above mentioned sericin modifier not only had excellent antistatic performance, but also hygroscopicity property and so on. The surface charge of treated fabrics with and without sericin modifier were measured, which greatly reduced after finishing. And the contact angle declined obviously. The strength of the fabric treated alkaline deweighting reduced clearly from 519 N to 277 N, however, it reinstated the original strength because sericin modifier grafting onto the polyester fabric could prevent the movement of molecular chain. Alkaline deweighting of polyester fabric decreased fabric density which increased the gas permeability and still reinstated the good property after treating with sericin modifier. Infrared spectra (FTIR) showed that sericin modifier was fixed on the polyester fabric treated alkaline deweighting successfully.

A Durable Superhydrophilic Modification of Polyester Fabric

In this paper, a durable superhydrophilic modification was applied to polyester fabric to improve its wettability- HAS treatment. The wetting ability of HAS treated polyester fabric improved a lot; the water contact angle could decrease to 00 in 3s; the water content increased up to 115%; the wicking distance increased up to 15cm; spraying rate improved to 1 degree. The wearability tests showed the breaking strength and creasability remain almost the same as untreated polyester fabric.

Enzymatic preactivation of PET substrate for improved interaction with photocatalytic systems and stability

Enzymatic modification of polyester fabrics by an esterase enzyme was used for improvement and prolongation of the photo-catalytic activity of TiO2 nanoparticles. Increased hydrophilicity of the fabric after enzymatic processing gave a higher quantity and better homogeneity of TiO2 nanoparticle deposition. The technology of TiO2 nanoparticle application was optimized and the final properties of finished polyester fabric were evaluated. The photo-catalytic effect was assessed by testing of air pollutant (formaldehyde and ammonia) degradation and by determination of antimicrobial properties of the finished polyester fabric.

Property and Application of Rabbit Protein Powder

Rabbit hair is a kind of animal hair, containing a large amount of keratin which can be extracted. According to the preparation method of wool protein powder, rabbit hair powder was obtained, and the morphology of the protein powder was observed by microscopy. By reacting with the alkali solution, two kinds of protein powders which were prepared from rabbit hair and wool, were used in modification of polyester fabric. Experimental results showed that samples with rabbit hair protein powder has evident improvement in moisture absorption of polyester fabric compared with untreated and wool powder treated samples, while UV protective properties of sample treated by rabbit hair powder was unexpected decreased, a further investigation will carry out to explain it.

Modification of polyester fabric by chemical/thermal treatment to improve dyeing ability

Attempts were made to enhance the dyeability of polyester fabric by thermal treatment or combined chemical/thermal treatment in hot air or in steam, either slack or under load. Ethanolamine, hydrazine hydrate, ethylene glycol and a benzophenone derivative were applied to the fabric by padding technique prior to the thermal treatment. The dyeability of polyester fabric was found to be improved at nearly boiling without using carriers and/or high‐temperature/high‐pressure techniques. The rate of dyeing of chemically/thermally treated polyester fabric was found to increase. Differential thermal analysis of the polyester samples was interpreted in terms of dyeability improvement. The glass transition temperature of the treated fabric was found to decrease compared with the untreated one, resulting in an enhancement in the dyeability of polyester fabric with disperse dye.
