It is showed that through selecting proper process parameters,using the grafting equipment which is over 70 percent made in China to produce 220 dtex/36 f and 110 dtex/24f chinlon 6 FDY in same scale ,the high quality chinlon 6 FDY can be obtained,the firsts ratio is over 96%.
It is very hard to prepare Nylon high speed spinning finishes because of Nylon fiber's special structure and high speed concomitancy with high temperature in spinning and false twisting process. So there is a marked disparities in Nylon high speed spinning finishes researching between China and some advanced countries .
Nylon, chitin, polyvinyl chloride, and polymethyl methacrylate molecular sieves with pores of various size are studied as membrane surface modifiers in electrodes reversible to anionic surfactants.
Deletion ΔF508 has been revealed in PCR-amplified regions of human gene CFTR by color detection of the hybridization complex obtained by ligation of a tandem of short oligonucleotides on a DNA template followed by UV immobilization on nylon.
To obtain the oligonucleotide array, 60-mer oligonucleotides regularly distributed throughout the genome region of interest at 2-kb intervals were immobilized on a nylon filter.
The Brill transition of even-even polyamide 618 was investigated using differential scanning calorimetry (DSC), temperature-dependent wide angle X-ray diffraction (WAXD) and Fourier transform infrared (FTIR).
The X-ray diffraction results indicate that the melt-crystallized sample of polyamide 618 transforms from the triclinic unit cell to the pseudo-hexagonal phase in the range of 120-180°C.
Neutrophils can be directly stimulated by endothelial cell suspensions, an observation that has also been made by experiments with nylon fiber, as an artificial model for PMNL/EC interactions [5].
Populations enriched for T cells by E-rosetting or nylon fiber filtration showed unimpaired responsiveness to BCG, while populations depleted of T cells by E-rosetting showed neither "natural" cytotoxicity nor augmentation of cytotoxicity by BCG.
