In order to improving poor wettability, mechanical property and rejection rate to water soluble dyes, the electrospun PSF fibrous membrane was padding with 2%-0.4% and 2%-0.48% chitosan solution cross-linked by glutaraldehyde. The wettability, mechanical property, and filtration property to disperse blue 2BLN and weak acid blue N-RL with dead-end filtration method under constant pressure 0.1MPa of electrospun PSF fibrous membrane before and after treatment were studied . The result showed that the wettability and mechanical property of electrospun PSF fibrous membrane have significantly improved after treatment. It also showed that the untreated and 2%-0.4% fibrous membranes had high rejection rate to disperse blue 2BLN which were all above 94%, and low rejection rate to weak acid blue N-RL which were all under 35%, but both of them had high filtration flux. However, the 2%-0.48% fibrous membrane had much higher rejection rate to disperse blue 2BLN and weak acid blue N-RL, was 99.5% and 92.4%, respectively, but the filtration flux was decreased greatly.

For the hydrophilic modification of isotactic polypropylene (PP), PP/TWEEN20 blends were mixed via a co-rotating twin screw microcompounder, then the blends were electrospun to fibers. The PP/TWEEN20 electrospun fibers were performed by Attenuated Total Reflection Fourier-Transform Infrared (ATR FT-IR) Spectroscopy, X-ray photoelectron spectroscopy (XPS) and Contact Angle Measurements. The thermodynamics of electrospun fibers was measured by Differential Scanning Calorimetry (DSC) analysis. FT-IR spectrums indicated PP had been blended with surfactant TWEEN20. After blending with surfactant TWEEN20, the contact angle of the electropsun fibers was reduced considerably especially when the load of surfactant TWEEN20 was up to 3%. The electropsun fibers exhibited excellent hygroscopicity, whose contact angle was zore, even when the load was 5%. XPS results demonstrated substantial enrichment of the surfactant TWEEN20 segments on the surfaces.

To exploer the relationship batween the feature of spinning guider' s movement and the qualities of ring spun yarn, a yarn gueder movement model was developed during the whole ring bobbin yarn package formation process, and arc length change was analyzed for the staple strand wrapping on the front roller within yarn formation zone. Then, the spinning triangle geometric square variations were investigated with the forementioned arc length change, and influence of above variations on spun yarn properties were also predicted, theoretically. Theoretical analysis indicated that spinning guide going up and down periodically led to the corresponding changes of decreasing and increasing geometric square of spinning triangle zone, influencing yarn hairiness directly. Experiments were also carried out to confirm theory above. Experimental results showed that yarn hairiness decreased as the responding decreasing geometric square of spinning triangle zone in the same position of packaging; the properties of whole bobbin yarn’s hairiness was influenced by spinning triangle’s changes, the size of yarn loop and so on.

Owing to its low contrast, the defects of fabric images for background texture saliency are not very salient, and they are difficult to detect automatically. Aimed at this problem, a method for fabric defects detection based on texture saliency features is proposed in the paper. Firstly, in view of robustness of Tamura texture features, good discrimination and rotation invariance to texture, we present an improved local texture coarseness algorithm(ILTCA) based on multi-scale calculation in order to further enhance discrimination to local texture. Then on a fabric image, coarseness, contrast and direction are calculated respectively based on optimal scale of local textures in accordance with ILTCA and three characteristic sub-maps are obtained, a salient feature map is formed by normalization and weighted fusion for difference sub-maps. Finally, comparing with the existing methods of fabric defects detection based on visional saliency feature, the comparing experiment results on the TILDA texture databases show that the proposed method can effectively isolate fabric defects from salient background texture and fabric defects detected has good homogeneity and integrality.

To solve the issue of time performance in fast fashion product development process, this paper constructs a system dynamics model of product development process based on the practical case of a fast fashion brand S, and build a simulation experiment platform. With the basic framework “strategy-resources-performance”, the simulation experiments of resource allocation are carried about 7 key variables in process, and the simulation estimated values of three key performance indicators (KPI), such as cycle time, delivery rate and MEAN flow, are forecasted. Using local sensitivity and entropy method, weight coefficients of cycle time, delivery rate and MEAN flow are recognized as 53.5%、2.7% and 43.4%. According to weight coefficients and time-based competition strategy of brand S, time performance of process is evaluated comprehensively. The research shows that variables of batches, rate of designing clothing and fabric repeat usage have a great effect on the time performance of process. When layout batches reduce about 25%, the total time performance is optimal.

To solve the problem that roving strand broken of siro-spinning is difficult to be discovered in time during the process of production, the square wave signal is checked in this paper by using the principle of photoelectric detection,which is caused by the yarn rununing the front of detection probe before and after roving strand broken. There is a clearly difference between each wave signal width values before and after the roving strand broken by the transverse and longitudinal comparison to change features of each wave signal width values, which can be used to judge whether there is a roving break phenomenon .In this paper, experiments spinning the fineness of 29.2 tex combed cotton siro-spinning yarn were carried out on the FA507B spinning frame to validate the conclusion. The results showed that considering the influence of such factors as the yarn thickness, surface hairiness, change of balloon shape, the width of a single square wave increased by 0.3 ~ 0.4 times after roving strand broken. The case of siro-spinning roving strand broken can be indirectly judged by this change, thus it can provide theory bases for subsequent development of siro-spinning roving break stocks detection device.

Graphene is a two-dimensional nano-material with the thickness of only one carbon atom, which is consisting of carbon atoms in the hexagonal honeycomb lattice formed by sp2 hybrid orbitals, exhibiting high specific surface area and excellent electrical, thermal, optical and mechanical properties, as well as exceptional hydrophobicity/superlipophilicity. Therefore, graphene is promising in the fields of adsorption and separation due to its unique structure and properties. The paper gives a comprehensive review to the recent studies about the fabrication of graphene-plus adsorption functional materials (grapheme-based sponge, graphene hydrogel/aerogel, graphene/carbon nanotubes), graphene-plus separation functional membrane materials (graphene porous membrane, graphene-plus polymer separation membrane, layer-by-layer graphene membrane), and graphene-plus continuous oil adsorption and separation functional materials. Moreover, the research progress and application prospect in oil/water separation process were analyzed and investigated.

To explore diverse application of graphene in functional fiber and textiles, the multiple functions of the preparation of graphene composite fiber and functional studies were introduced through the products of the summary of our research of graphene composite fibers. The preparation of graphene/regenerated fiber and the features such as mechanical enhancement, flame retardant, thermal stability, prevent ultraviolet and infrared emission characteristics and weather resistant anti-aging of the composite fibers were studied. Graphene UV protection fabric, graphene oxide/chitosan composite conductive fabric, graphene far-infrared fabric, graphene oxide/sodium alginate composite film and the nanometer manganese dioxide/graphene modified fabric were produced and tested. Graphene composite fibers and products have a broad application prospect in far-infrared functional textiles, individual protection and intelligent textiles field.
