This paper describes the technology of chemical fibre spinning take up,points out the influence of the chuck tube driven by the friction roller at a constant speed on the quality of the original chemical fibre, and analyses the principle and the control method of the chuck tube take up driven directly.
The chemical fibre technology has been improved fastly along with development of science and technology,special for the fine denier,particular, porous,compound fiber and texture finishing technology, which creats broad development space for the products of polyester copy linen.
In order to make producing and application in an international leading position, we have to furtherly improve all kinds of drawing processes, and produce the fine finer slenderizing wool yarn, broaden the scope of product development, in the light of its special properties, we can break the pale of cotton wool, silk and hemp, make full use of new chemical fibers' special properties, establish variegated pattern of wool material, at last develop rich and high-additional products.
The demand for spinnerets with form holes has increased rapidly with the development of chemical fibers,but it is quite difficult or even impossible to machine the form holes by mechanical means,as used traditionally.
Based on the demands of domestic and foreign markets, and the development trend of chemical fibres, the author investigates the trend of blended and doubled fabrics from blended yarnsand their variety and specifications.
Urine samples from subjects, who had been using phenol for treatment of chemical fiber in factories, were analysed for urinary phenyl sulfate (PhS) and phenyl glucuronide (PhG) by high-performance liquid chromatography (HPLC).
The study was initiated in response to odorcomplaints from residents of neighborhoods located adjacent tothe largest chemical fiber manufacturing plant in Taiwan.
Filtration of spinning solutions, spinning bath, and finishing solutions through a layer of fibrous material is widely used in different chemical fiber plants.
A user-friendly program was created based on the theoretical principles of fibre formation during melt spinning; it allows the engineer in the chemical fibre industry to very rapidly evaluate the efficiency of certain technological measures.
A spinneret is the critical part which influences the yarn formation directly.The demand for spinnerets with form holes has increased rapidly with the development of chemical fibers,but it is quite difficult or even impossible to machine the form holes by mechanical means,as used traditionally. It is our aim to describe in this paper that a new technique——the Supersonic—electrodischarge technique is applied to machining the form holes of various kinds and its practical results achieved in our tests. "The cr...
It is necessary to subject man-made fibre fabrics to a rising-temperature treatment during the finished process,and a good knowledge and control of the fabric temperature has an important bearing on their quality and output.With this in view,we tried the radiation method in measuring the surface temperature of fabric,i.e.by using an instru-ment which directly receives the radiant energy from the fabric. The value of emissivity ε varies With different structures of materials.It has been proved by our experim...
In this paper,the amount and distribution of twist in the principal man-made OEyarn cross-sections are studied.An approach is made and a preliminary solution is found to the problem aboutthe formulation of spinning solution for tracer fibers to be used for observing PETand vinylon OE yarns.The results show that the rules of twist distribution in man-made OE yarns arethe same as cotton OE yarn.It has also been observed that the measured values of practical twists in man-madeOE yarns are the same as those in ...
