In order to improve the shrinkproofing of wool fabrics, surface modification of wool fabrics was carried out by low-temperature plasma/protease treatment. The changes in the shrinkproofing and breaking strength properties of the treated fabrics were studied. Through testing the color performance indexes, it mainly discussed the influence of dyeing properties by shrink-resistance treated. The changes in the morphology of the treated fabrics were investigated by using SEM. The results showed that the morphology and microstructures were changed. The treated fabrics can not only get 5. 4% shrink proof but can improve the dyeing property. The low temperature of wool dyeing was possible. Source

In this paper, Savannas protease is selected to treat wool fabrics for shrink-resistance. It is studied that the effect of the non-chlorine oxidant H2O2 for pretreatment on protease treatment of the wool fabrics. It got the preliminary experimental parameters through testing of enzyme activity. Used two methods of single factor analyzed and multilevel orthogonal design to get the best process parameters; protease dosage 3% (owf), pH value 7, temperature 55°C, time 40 min, bath ratio 1: 30. The result showed that the shrinkage of the treated fabric has reduced to 5.60%. As a result, protease treatment renders wool fabric good shrink resistance. Source

This research is mainly to investigate the thermal and crystalline differences between polyamide 6/montmorillonite (PA6/MMT) and polyamide 6/organomontmorillonite (PA6/O-MMT) nanofibers, which were both prepared by electrospinning under the same process conditions. The structures of PA6/MMT and PA6/O-MMT nanofibers were observed by scanning electrical microscope. It was identified that the interval between O-MMT clays was increased in the PA6 matrix compared to that of MMT, which was detected by X-ray diffraction (XRD). The thermal properties of PA6 nanofibers contained O-MMT particles were more efficient than PA6/MMT nanofibers, that was verified using thermal gravimetric analysis. The crystalline properties of the electrospun nanofibers was investigated using differential scanning calorimeter and it was found that the degree of crystallinity in the PA6 nanofibers loaded with O-MMT was much higher than PA6/MMT and PA6 nanofibers. © 2010 Wiley Periodicals, Inc.
