A stochastic thermal-conglutination profiled filament is disclosed. The profiled filament varies, according to the change of the process condition, in one or more of fiber structure, total linear density, monofilament density, number of monofilaments, shape of cross section of the monofilament, radial degree of profile of the monofilament DR %, three-dimensional structure of the monofilament, and physical property of the monofilament along the axial direction of the filament of the infinite length.

Polypyrrole (Ppy)-coated viscose fibers have been prepared by vapor phase and liquid phase pyrrole deposition technique, respectively. Comparative morphological and electrical property analysis was carried out on the viscose fiber prepared with both vapor and liquid phase processes. The result showed the configuration of Ppy coatings and electrical property had a strong relation with the deposition technique. Ppy-coated viscose fiber prepared by vapor phase show a high uniform polypyrrole coatings, fine Ppy granular structure, lower electrical resistance, and good fastness performances to abrasion. © (2011) Trans Tech Publications.

The two deposition polymerization techniques, i.e. vapor phase and liquid phase pyrrole deposition polymerization were applied to Ultra-high-molecular- weight polyethylene (UHMWPE) fiber in this paper. The effect of deposition technique on the surface morphology, mechanical properties, electrical stability and surface roughness of fibers were discussed. The result showed that deposition technique has a strong effect on the properties of UHMWPE fibers. Fibers treated by vapor phase deposition polymerization has much fine and small granular structure, lower resistance, better mechanical property and higher surface roughness value. © (2012) Trans Tech Publications.

Native corn starches were acid-treated at 53 °C for hours in HCl aqueous solution. The peak temperature (Tp) and heat of gelatinization (ΔHgel) before and after treatments were determined. The average particle size, TG and viscosity were measured. The results showed that the viscosity of corn starch decreased from 630mPa to 4.6mPa after acid treatment for 6h. The average particle size decreased andΔHgel decreased obviously after acid modification.

Carbon black/polyester (CB/PET) electrically conductive fibers were prepared by melt spun method. The effect of coupling agent on the percolation threshold concentration and Tg of CB/PET fiber was discussed, and the relationship of CB content with thermal and electrical properties of CB/PET fibers was investigated. The results showed that percolation threshold content and Tg of CB/PET fiber were decreased after CB being treated by coupling agent. And CB content has a strong effect on the properties of CB/PET fiber, i.e. the positive temperature coefficient effect of CB/PET fiber moves to higher temperature with CB content increasing; CB/PET fiber has a strong positive strain coefficient effect when CB content is 11%. ©.
