Application of Spacer Fabric for Protecting Cushion

Spacer fabric is a typical three-dimensional fabric, including upper layer, lower layer, and spacer layer. It is widely applied in protecting cushion products for unique space structure, which attributes good comfortability to infants and the disabled elderly in reducing diseases resulting from hot and humidity under long-time sitting and lying period. It necessitates studying the microenvironment change between body and clothes and corresponding performance. Compressibility. air permeability, heat and moisture permeability, and bending and humiture in microenvlronment of spacer fabric are analyzed and compared with foam cushion and nonwoven cushion. Experimental results show that corresponding performance of spacer fabric is better in protecting cushion than those of foam and nonwoven. Compared with traditional foam cushion and non-woven cushion, spacer fabric is more suitable for protecting cushion, and provides an alternative and optimal cushion material in medical products to protect infants and the disabled elderly from bedsores resulted from long-time sitting and lying.     

Fabric Defect Detection Using GMRF Model

It has been testified that the Gauss Markov random field model is most suitable for the characterization of fabric texture among a variety of available models because of its approximately constant character and the normality of the gray-level distribution found with typical fabric images. However, the general Gauss-Markov random field(GMRF) method for fabric defect detection is not always ideal in practice since in some cases, the estimated model parameters make the Markov error covariance not positively definite, which may render the method to fail thoroughly. In this paper, the use of the GMRF model for defect detection of fabric is discussed and an approach to this problem is proposed. Some detailed texture may be overlooked in this way, but good detection results can still be expected as far as fabric defect detection is concerned.

Photo-Grafting Copolymerization of PP Nonwoven Fabric and Its Application for Acidic Dye Adsorption and Filtration

The monomer methacrylamido propyl trimethy ammonium chloride（ MAPTAC） was copolymerized onto the fiber surface of polypropylene（ PP） nonwoven fabric under ultroviole radiation. The weak acid red GN dye adsorption and adsorptive filtration performance of the resulted PP fabrics were investigated.The results showed that the grafting copolymerization preferred to happen in the inner layer of the fabrics. The water flux of the grafted fabrics decreases with the increase of grafting yield. The collapse of the grafted polymer chains causes the flux increase in acidic condition,or vice versa at alkaline version. The coiling of the polyelectrolyte chains upon the dye adsorption seems to violate the routine assumption of the rigid substrate, and this gets the adsorption energy constant negative. The static adsorption process follows the Lagergren＇s pseudo-second order kinetic equation. The removals of circa（ ca.） 100% of the total permeation volume3 500 mL simulated dye wastewater was reached during permeation.The dye adsorbed fabrics were regenerated by the mixed media of the cationic surfactant / ethanol /water. The grafted fabric assumes stable fabric integrity and stability during permeation,and presents excellent dye adsorption capacity,easy desorption, and repeatable utilization.
