      To investigate the adsorption of electrospun fiber film to heavy metal ions, the Cu (II) adsorption performance on such material was stdied based on successful preparation of the electrospun fiber film naturally brown cotton. The electrospun fiber film material had much higher adsorption volume of Cu(II) than that of the correspondent raw brown cotton, which was 3~5 times of that of raw cotton material under different pH conditions. After carboxylation modification, the electrospun fiber film could increase its Cu(II) adsorption volume greatly. Under the conditions presented in the paper, the adsorption volume could be as high as about 250 mg Cu(II)/1g electrospun fiber film. Carboxylation modified electrospun fiber film had high rate adsorption performance, and at least 80% of the total adsorption volume could be finished in 16s. The adsorption of Cu(II) on carboxylation modified electrospun fiber film is in the mode of single molecular layer adsorption and had adsorption saturability. The theoretical maximum adsorption volume for prepared material was 526.3 mg Cu(II) /1g electrospun fiber film with a Langmuir constant of 7.133×10-6 L/mg.

      Cellulose lauric acid esters/polyethylene glycol (LACE/PEG) graft copolymer fibers with excellent phase change energy storage performance were successfully prepared by grafting PEG on LACE to obtain LACE/PEG graft copolymer solution, and electrospinning. The effect of  PEG content of the LACE/PEG solution on the fiber morphology,phase change energy storage properties, and the stress-strain characteristics were studied. Also, the usability and effectiveness of the prepared LACE/PEG graft copolymerization fibers were analyzed by washing and cycle thermal stability test. The results showed that the LACE/PEG solution with different PEG content all can be spun to obtain cylindrical fibers with smooth surface. However, the diameter and phase change enthalpy were increased, and the uniformity and mechanical properties of the LACE/PEG fiber were decline with the increase of PEG content in the spinning solution. Additionally, since the PEG and LACE both have phase change energy storage characteristics, and they couldn’t be washed out easily as they were linked by chemical bonds, the LACE/PEG fiber exhibited a completely reversible phase transition with high enthalpy, moderate temperature and good thermal cycle stability, indicating that it is an ideal phase change fiber with high use value.

      Silver nanoparticles (AgNPs)/TiO2/celllulose acetate (CA) composite nanofibers were successfully prepared by using TiO2 and AgNO3 as additives, and electrospinning. The obtained composite nanofibers were characterized using scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy separately. The antibacterial property of the composite nanofiber was further evaluated by the agar diffusion method. The results show that the surface morphology of the composite fibers could be effected by both AgNPs and TiO2 in a content-dependent way. An interaction exits between the oxygen atom of CA and AgNPs in the nanofibers. An obvious absorption peaks in visible light wavelength region could be observed due to the existence of AgNPs in the nanofiber. The synergistic effect of AgNPs and TiO2 provides the composite nanofiber with a remarkable antibacterial property against Escherichia coli and Staphylococcus aureus.

      For the purpose of real-time detection on the damage of 3-D braided composite materials, this paper proposes the new way of the carbon nanowires sensor enbedded into 3-D braided composite material by three-dimensional five-derection four-step method. Carbon nanowire sensor bas similar property with carbon fibers, thus, it has little impact on the carrying performance after carbon nanowires are embedded into the 3-D braided composite material part. The paper analyzes the correlation of the rate of change of its resistance and strain on parts of 3-D braided composite materials b three point bending experiment. The experiment result shows that the resistivity of embedded carbon nanowires has exponential fitting relationship with the strain of 3-D braided composite material parts under stress. Hence, the damage of 3-D braided composites can be monitored by the corelation function of the resistance change rate and the stress or strain.

      To study the application of the calculation model of carbon emissions in the garment production process and the influence of cthe arbon emissions in actual production on the environment, a quantitative model proposed in this study was applied and analyzed. Takeing a male shirt as an example, flow analysis, functional unit analysis, data collection and calculation of carbon emission are performed on the male shirt. The results indicated that in the production process of male shirts, the amount of the carbon emissions during the whole process is higher than that of the fabric used in production. The amount of the carbon emissions generated from sewing lind is highest. This method can also be applied to the production of other styles of clothing, providing a basis and reference for carbon emissions monitoring and evaluation for garment manufacturers in the production processes.
