  fiber cell
This phenotype is associated with lack of fiber cell initiation in the outer integument of the ovule, as was characterized by analysis of genes related to fiber differentiation and development.
      
The fiber cell also demonstrates back pressures which are a factor of 50 less than the conventional cell and much less susceptibility to absorption of compounds because of its lower surface area.

The dynamic mechanical properties of polyethylene terephthalate (PET) monofilament samples with different crystallinity and draw ratio were determined over 100 to 430°K using the vibrating reed method. In this temperature range two internal friction peaks were observed at 243°K (βc) and 354-383°K (αa). The ft and βc peaks were shown to be influenced by the variation of crystallinity. From the view point of Takayanagi's mechanical model of crystalline polymers, the βc absorption may be attributed to the local...

The dynamic mechanical properties of polyethylene terephthalate (PET) monofilament samples with different crystallinity and draw ratio were determined over 100 to 430°K using the vibrating reed method. In this temperature range two internal friction peaks were observed at 243°K (βc) and 354-383°K (αa). The ft and βc peaks were shown to be influenced by the variation of crystallinity. From the view point of Takayanagi's mechanical model of crystalline polymers, the βc absorption may be attributed to the local twisting motion of the molecular chains in the frozen noncrystalline phase and in the defective region within the crystalline phase, and the αa absorption to the translational motion of the segments in the noncrystalline region.The temperature of the αa peak increases with increasing draw ratio, while the βc peak remains unchanged. This suggests that the stretching of PET fibre would mainly change the interchain interactions in the noncrystalline region.Takayanagi's method of determining the crystallinity of PET samples from the loss moduli of βc and αa peaks was confirmed for the fibre samples.

用声频共振法在 100—430°K温度范围内研究了结晶及拉伸取向对 PET纤维分子运动的影响。在研究的温度范围内PET出现两个转变,243°K(β_c),354—383°K(α_a)。拉 伸使α_a转变显著移向高温,而β_c转变基本上不随拉伸比改变,这说明PET纤维的拉伸主要改变了非晶区分子链间的相互作用。 根据高柳的力学模型及建议的方法从α_a及β_c转变的损耗模量峯值计算了PET的“结晶度”,说明用密度法测得的结晶度反映了晶区与晶区缺陷部分的总和。

The degradation of PPTA main molecular chains is appraently accompained by intermolecular branching and cross-linking.

During heat-treatment of PPTA fibre, changes occur in strength, modulus, inherent viscosityanb and solubility. The degradation of PPTA main molecular chains is appraently accompained by intermolecular branching and cross-linking. The measurement of intrinsic viscosities (η) of the fibre heat-treated under tension at 340~590℃ in 96% H_2SO_4 solution indicates that with the increase of the temperature of treatment, Huggin's parameter rises, and the GPC curves move regularly in the direction of higher molecular weight. Their dist(?)ibution also broadens. This verifies that degradation, branching and cross-linking of PPTA macro-molecular occur simultanously. On the basis of fundamental investigation, the branching degree and its distribution of the fibres heat-treated under tension at 410℃ are determined by incroporating GPC method with the (η) one.

This paper investigates by means of LPY-4B induction type electrometer the (?)fluences of relative humidity, impurities and the molecules orientation of polyester fibre on the static voltage of fibre and the half decay period of charges on the fibre. There is a maximum voltage value at 45~60% relative humidity for silk, wool and synthetic fibres and the half decay period of charges quickly shortens when relative humidity increases. The voltage reduces and the half decay period shortens greatly as impurities are added. The voltage rises as the molecule orientation of polyester fibre is enhanced in experimental range.
