Hydrophilicity Modification

The hydrophilic modification of poly (ethylene terephthalate)(PET) fabric is significant for industrial production. Its studied by ultraviolet radiation, nanoTiO2, H2O2 and NaOH. The results show the best condition is 3%nanoTiO2, 5%H2O2 and 3%NaOH, under 1000W UV radiation. With only about 30~35 minutes irradiation the PET fabric is nearly to wettable. For 40 minutes irradiation is super hydrophilic, the water contact angle of modified PET fabric can decrease to zero in 3 seconds. The wettability of modified PET fabric was examined. It shows the water absorption of modified PET fabric increase from 85% to 104%, and the capillary rise height can reach from 0.2 to 6.2 cm. Meanwhile the broken strength and elongation change of modified PET fabric tests show its mechanical and physical properties keep good.

As the surface of polyester fabric is hydrophobic, it is not comfortable to wear. In this paper, the surface of polyester fabric was ionized by an ionic agent. The result showed that the ionized polyester fabric had wonderful hydrophilicity. The water contact angle of ionized polyester fabric decreased to 0o, and the capillary rise height increased from 0.4cm to 14.4cm, water content from 23.77% to 119.78%. Water spraying rate decreased from 4 degree to 1 degree. The whiteness of ionized polyester fabric kept well.

The PET fabric surface was modified with ultraviolet radiation and nano-TiO2. The wettability and the broken strength of the modified PET fabric were studied. The results showed that with the increase of the ultraviolet radiation irradiation, the water contact angles of modified PET fabrics decreased greatly. Water contact angle of PET fabric modified with 40g/L nano-TIO2 and 60 min ultraviolet radiation irradiation could decreased to zero in 4.11 seconds. And the capillary rise height of modified PET fabric could increase from 1.1 mm to 110.2 mm. The spraying rate of modified fabric could decrease from 4 to 1 degree, and the water absorption could increase 89.86%. These showed the hydrophobic PET fabric could be modified to super hydrophilic PET fabric. The broken strength of modified PET fabric not only did not decrease, but also increased a little. The broken elongation kept well.

Poly(ethylene terephthalate) (PET) fabric-reinforced polyvinyl chloride (PVC) composites have a wide range of applications, but the interface bonding of PET fabric/PVC composites has remained a challenge. In this work, a new in-situ SiO2/tributyl citrate sizing agent was synthesized according to the principle of “similar compatibility.” The developed sizing agent was used as a PET surface modifier to enhance the interfacial performance of PET fabric/PVC composites. The morphology and structure of the PET filaments, the wettability and tensile properties of the PET fabric, the interfacial adhesion, and the tensile and tearing properties of the PET fabric/PVC composites were investigated. Experimental results showed that many SiO2 nanoparticles were scattered on the surface of the modified PET filaments. Moreover, the surface roughness of the modified PET filaments remarkably increased in comparison with that of the untreated PET filaments. The contact angle of the modified PET filaments was also smaller than that of the untreated ones. The peeling strength of the modified PET fabrics/PVC composites was 0.663 N/mm, which increased by 62.50% in comparison with the peeling strength of the untreated ones (0.408 N/mm). This work provides a new approach to the surface modification of PET and improves the properties of PET fabric/PVC composites.

This work aimed at effective chemical recycling of waste poly(ethylene terephthalate) (PET) fabrics into water-soluble polyester (WSP). For this, PET fabric waste was depolymerized using excess ethylene glycol (EG) in the presence of zinc acetate as catalyst. The glycolysis product of PET, bis(2-hydroxyethyl) terephthalate (BHET) was then used to synthesize WSP by a three-step method, that is, transesterification, esterification and polycondensation. The structures of BHET and WSP were identified by Fourier transform infrared spectra. Sizing performances of WSP were studied, and it was found that the surface tension of WSP size (57 mN/m, 22℃, 0.5% of weight) was lower than common sizes, the viscosity of WSP size was 1–2 mPa·S (95℃, 6% of weight) and the viscosity stability was larger than 90% at this temperature. The mixture of WSP and starch showed stronger adhesion to polyester–cotton roving and polyester roving than onefold starch. K/ S values of fibers before sizing and after desizing showed a slightly difference, which indicated that WSP would not influence the color of yarns when used as the sizing agent.

In this paper,the soybean protein / poly (ethylene terephthalate)PET composite fabric was obtained and its wearability was mainly studied. It is found that the moisture regain, water absorption, air permeability and moisture permeability of soybean protein PET composite fabric were improved greatly. In addition, the whiteness and elastic wrinkle recovery angle kept well, and the stiffness increased incredibly. Therefore, soybean protein being grafted on PET fabric surface not only improved the biocompatibility, but also the wearability.

In this study, –NH2 groups were introduced to a poly(ethylene terephthalate) (PET) fabric to make the fabric hydrophilic and, then, soybean protein was bonded on the surface of the modified PET fabric to obtain a soybean protein/PET composite fabric. The –NH2 groups allowed the soybean protein to be firmly bonded on the surface of the modified PET fabric. Scanning electron microscopy images showed that the surface of each modified PET fiber had a small number of grooves and that there was a thin film on each soybean protein/PET fiber. Attenuated total reflectance Fourier transform infrared spectra demonstrated that the nitrated and reduced PET fibers were introduced –NH2 groups and that there were –CO–NH– groups on the surface of soybean protein/PET fibers. X-ray photoelectron spectroscopy analyses showed that there was a nitrogen element on the modified PET fibers. The X-ray diffraction patterns suggested that the crystal structures of the modified fibers did not change significantly during the modification processes. The thermogravimetry results showed that the thermal stability of soybean protein/PET fiber kept well. The wearability tests indicated that the breaking strength and elasticity of the original fabric were well retained by the modified fabrics. The soybean protein/PET fabric had good levels of hydrophilicity and softness when the binding rate was below 3.0%.
