The cement-free binding material, namely geopolymer, is a novel binding material made from solid waste such as fly ash and slag activated by the alkali. In this research, orthogonal tests were carried out on 20 x 20 x 20mm cube paste specimens cured at room temperature to explore the rules of influence factors according to the compressive strength for 3d, 7d and 28d. The results revealed that the ratio of fly ash/slag is the most significant factor, the ratio of water/ (fly ash+ slag), the modulus of alkali activator and the dosage of desulfurized gypsum also play great role in strength development of the binder. The compressive strength of the specimens can be obtained to 65.0 MPa and 51.21MPa at maximum for 28d when the ratios of fly ash/slag are 30/70 and 40/60 respectively.

The effect of atmospheric pressure dielectric barrier discharge plasma treatment on desizing polyvinyl alcohol (PVA) on polyester fabric was discussed as compared desizing with alkali through a combination of desizing rate, field scanning electron microscopy and strength test. The dyeing properties of polyester fabrics treated with atmospheric plasma have also been studied. The results show that plasma treatment can improve desizing rate, surface color depth and dye-uptake for polyester fabric.

According to the demanded functions, a novel hardening accelerating and water reducing admixture has been excogitated which is based on a polycarboxylate superplasticizer and cooperated with some other hardening accelerants at the same time, and has many merits such as chloride free、sulfate free、low total alkali content、low dosage、high water reducing rate、high early strength and so on. The performance of this admixture has proved to be outstanding especially in accelerating the early strength of 12 hours and 24 hours age in the concrete tests.

waterborne sodium bisulfite－blocked polyurethane was using polyether diols(N210), isophorone diisocyanate (IPDI) as the main material, sodium bisulfite as blocking agent, ethanol as the cosolvent. The effect of temperature and time of blocking reaction, alcohol than water were carefully studied. The best process parameter of blocking reaction: the temperature was 20°C; the reaction time was 45min; n(NaHSO3):n(NCO)=1.1; alcohol than water=1.85; the deblocking temperature determined by DSC was about 76～130°C

Kinetic analysis of silicon carbide prepared by carbon-thermal reduction is introduced in this paper. Through the dynamic analysis, kinetic parameters of Si-C are calculated, and it is estimated that the time required reaction materials of different diameter completely converted to SiC at different temperatures. Reaction time is nearly 1 hour long when the reaction particle diameter is 1μm around 1900K.

An anti-UV complex coating based on Ti sol for bombyx silk fabric was prepared. The process included using sols prepared by tetrabutyl titanate hydrolysis. The coating for the samples was prepared using the sol-gel method. Data from WAXD and TGA indicated that the properties of treated fabric showed little change when sol was introduced. SEM analysis was carried out to study the morphology of the fibers. Compared with the original sample, the UPF value of the treated sample increased from 31.99 to 213.09 with a high anti-UV performance.

C.I. Reactive Red 195 was used for non-aqueous dyeing in D5 (Decamethyl Cyclopentasiloxane) and appropriate surfactants were selected to ensure the dyes dispersed stably in D5 medium. The feasible method for reactive dyeing in dyes/D5 suspension system was established through repeated experiments. At the same time, taking the color depth (K/S value) as the evaluation index, the process factors in dyeing such as temperature, dyeing duration, pick-up ratio of alkali solution on fabric, as well as the alkali concentration were optimized for setting up dyeing conditions. The results showed that, the dye up-take could reach nearly 100% without any salt as accelerating agent. Since just a little water was used in the process, hydrolysis of reactive dyes was restrained, fixing rate was increased, and the apparent color depth of the dyed sample was much better than traditional water bath dyeing. The washing fastness and rubbing fastness of samples dyed in dyes/D5 system were satisfactory.

A temperature-sensitive N-isopropylacrylamide (NIPAAm) grafted cotton fabric was prepared by the plasma-induced graft polymerization technique. The surface morphology of the grafted fabric was observed from field scanning electron microscopy (FSEM). Fourier transform infrared spectroscopy (FTIR) and DSC were used to characterize the structure and thermal property of the grafted fabric. The results showed that the PNIPAAm was grafted onto cotton fabrics. The DSC analysis results indicated that LCST value of the grafted fabric was around 32 °C. The water permeation flux of the grafted fabric varied dramatically with a slight change at temperature around the LCST, which showed that the grafted PNIPAAm could act effectively as a chemical valve to control the on-off behavior of cotton fabrics.

This study presents an experimental investigation of the relationship between liquid surface tension and fabrics water retention in dehydration processes such as centrifuging, line drying and heat drying. Selected surfactants were used to prepare wash baths with different surface tension, and dehydrating experiments of cotton fabric after immersion in above bath were conducted. The results showed that lower surface tension is beneficial to reducing fabrics water retention by centrifuging and improving line drying efficiency and heat drying efficiency. It was assumed that water with low surface tension is easy to drop down or separate from fabric, thus improving the de-watering and drying efficiency.

During the transmission of ultrasound, its great directionality, ubiquitous penetration and the ability to strengthen the diffusion, exchange and transfer of matter can help the treating fluid reach the crossing points of silk fabric. And the function of ultrasonic wave can make use of acoustic cavitation effect to produce impact on sericin layer at the crossing point, thus promoting the fragmentation and separation of sericin, improving the removal efficiency of sericin at crossing points and achieving uniform silk fiber degumming. The function of ultrasonic wave can cut down the time of process and avoid the damage of fibroin through controlling the temperature and dose of chemical agent.

In order to understand the effect of laundering by detergent containing bleaches on cotton fabrics, two detergents with and without bleaches were used during laundering, and the changes in structures and properties of cotton fabrics were investigated after laundering. The structure of the cotton before and after laundering was evaluated by the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and field scanning electron microscopy (FSEM). Meanwhile, the tensile strength, copper number and dyeing properties of cotton fabric have been studied for evaluating the chemical damage. The results showed that the damage of fabric laundering by detergents containing bleaches is more serious than that by detergents without bleaches. FTIR and copper number results revealed that the C-6 hydroxyl groups of the glucose repeating unit of cellulose were oxidized. XRD, FSEM and dyeing results indicated that the cotton fabrics have been damaged during laundering with detergents containing bleaches.

A mesoscopic crystalline model was proposed to quantitatively analyze the relative activities of deformation modes involved in the plastic deformation of an AZ31 magnesium alloy at room temperature. The plastic response of a cast AZ31 magnesium alloy with random texture can be well predicted by this model. It is demonstrated that the remarkable difference of relative activities of pyramidal slip should be attributed to the different strain hardening behavior in tension and compression. Further TEM micrographs shows the occurrence of pyramidal slip in compression, which confirms the validity of the proposed model.

The performance of heat transfer coefficient, wicking and water vapour permeability (WVP) of cotton fabric were tested after adding amino-functional silicone softening agent in simulating process of home laundry. Meanwhile, the experiment of line drying of fabric soaked in water after spinning was designed to study the impact of soft nursing care on drying efficiency of fabric. The result showed that with the amino-functional silicone softening agent added, handle was improved obviously. With the concentration of softening agent increasing, WVP of fabric increased, while heat transfer coefficient had the opposite result. Wicking effect increased slowly at the beginning and decreased sharply later. It was found that soft nursing care improved the drying efficiency.
