With every self-twist of the yarn,there will co-exist,along the yarn length in the yarn projection on a plane,two points,where one strand is found exactly on top of the other,the dimension at either point being equal to twice the diameter of one strand.At the same time,midway between these two points,there will be a point where only one strand can be seen while the other is concealed,the dimension here being equal to the diameter of one strand. The number of self-twists can be obtained by loeating these points...

With every self-twist of the yarn,there will co-exist,along the yarn length in the yarn projection on a plane,two points,where one strand is found exactly on top of the other,the dimension at either point being equal to twice the diameter of one strand.At the same time,midway between these two points,there will be a point where only one strand can be seen while the other is concealed,the dimension here being equal to the diameter of one strand. The number of self-twists can be obtained by loeating these points and counting their numbers,wherein lies the working principle of our new automatic twist tester.In operation,a photoelectric transducer converts the detector recording into an electrical signal,which is electronically processed to give a digital count for each half self-twist (Z and S),and recorded by an SC 16 recorder.The deviation of the result from that by hand is about ±2%.

Low angle laser light scattering is a useful method for the measurement of molecular weight of polymer. In this work a convenient calibration method has been devised by using pure organic liquids of known Rayleigh factors to evaluate the instrument constant and the background simultaneously for a low angle laser light scattering photometer made in our laboratory.Considering the major background comes from the light scattered in the cell and the probability of stray light passing through the field stop is small, the Eayleigh factor may be rewritten as Rθ/n=φ[(Gθ/G0)-δ] for small scattering angles, where Gθ, G, are electrical signals propotional to the radiant power in the direction φ and in the direction of incident beam respectively, n is reflective index of liquid, δ is a factor related to the background, φ is an instrument constant. A linear relationship is obtained from the plot of Rθ/n vs (Gθ/Gθ) of the pure liquids such as toluene, benzen, cyclo-hexane, carbon tetrachloride and chloroform used for calibration. The slope of the straight line is φ and the intercept φδ is related to background. Performance of this instrument and the calibration method has been evaluated by measuring ten polystyrene samples of narrow MWD and good results were obtained.

本工作建议了一种比较方便可行的、用已知瑞利因子的溶剂标定激光小角散射光度计的方法。纯溶剂的瑞利值R_θ与其散射强度比(G_θ/G_0)有如下关系:R_θ/n=φ[(G_θ/G_0)-δ],式中n为溶剂折光指数;φ为仪器常数;δ为与背景有关的参数。以已知瑞利值的甲苯、苯、环己烷、氯仿及四氯化碳的R_θ/n对测定的(G_θ/G_0)值作图,得到了较好的线性关系,从直线斜率可定φ值。以此方法标定的仪器测定了十个聚苯乙烯窄分布试样均得到了满意的结果。

The determination of drafting force is of great help in specifying the manner a force is exerted on a fiber and all the relating factors,thus enabling us to have an overall understanding of the mechanism of the drafting process and the function of the drafting system.Several special devices are adopted.A cantilever is a steel leaf spring with linear elasticity.The strain gage attached to it is used as a transducer of drafting force.An electrical signal amplified through a resistance strain gage is recorded by a loop oscillograph.Experimental results show 1.In gill draft system the drafting force/draft curve(input sliver count being constant)is similar to the roller draft system in that they haven't obvious distinction, only the former's scope of critical draft zone is wider and the fluctuation of drafting force is larger. 2.The drafting force increases with the input sliver weight per metre linearly. 3.The pressure variation of front roller influences the drafting force slightly. 4.When the input ramie sliver is not orderly enough,the drafting force becomes greater. 5.The drafting force increases with the density of gill pins.

通过牵伸力的测定,纤维的受力情况以及各种影响因素能被充分地揭示。这帮助我们充分地认识牵伸过程及牵伸装置的详细作用。具有线弹性的肱梁是一根弹簧钢片,在上面贴着的应变片用作牵伸力的传感器,电气讯号通过电阻应变仪放大后用光线示波器记录。实验结果表明:1.在针排牵伸装置中,牵伸力和牵伸倍数的关系曲线(输入麻条支数不变)和罗拉牵伸装置相似,它们没有明显的区别,仅前者的临界牵伸区范围较宽而牵伸力的波动较大;2.牵伸力随着输入麻条重量/米线性地增加;3.前罗拉压力改变对牵仲力影响很小;4.当输入麻条结构较紊乱时,牵伸力较大;5.牵伸力随梳针密度而增加。
