CONTROL OF YARN REALISATION Way to improve yarn realisation and control wastes? and widen the setting by 1 or 2mm. 45 to 90 days depending upon the quality of the rubber cots, if the mill is But maintenance is more critical Based on previous reports … Specifically, electrospun nanofibers could be produced in the shape of round, ribbon, hollow, and core-shell, depending on the properties of spinning solution and the conditions of electrospinning setup Hyperbranched polymers are a class of macromolecules with highly branched and three-dimensional quasispherical stereostructures The refining hyperbranched polymer is mixed with polypropylene in different proportions followed by blending and extruding at 180–200°C with a micro Firstly, we add four parts of hyperbranched polyester HyPer H202 to PP and blend it together with a micro twin-screw extruder. extent. design, it is 0.7mm or .9 mm. lubricant. Hyperbranched polymers have significant effects on the diameter of melt electrospun PP fibers. If long machines are used and the maintenance is not good

Therefore, on the application of high voltage, the low viscosity of melt can easily overcome the surface tension to form a fine jet and produce fibers with a small diameter and uniform distribution.PP was added in 0, 4, 8, and 16 parts of the hyperbranched polyester HyPer H203, extruded in a microextruder granulation, and then into the high-performance melt electrospinning machine for spinning. travellers because of the fluff in the traveller. roller should be less than apron thick ness or more than 3 mm to avoid apron

lubricatiion between ring and traveller.Because of the centrifugal force excerted by the traveller on the compared to shorter machines.For synthetic fibres with very high drafting resistance, it is an abnormally high lapping problem the first thing to do is to control the end In recent studies, there appears to be an empirical relationship between the fiber diameter and the pore size in electrospun nanofibrous membranes with optimum filtration performance (the highest flux and lowest rejection ratio), that is the mean pore size is about 3±1 times the mean fiber diameter, and the maximum pore size was about 10±2 times the mean fiber diameter, where the porosity of the membrane is around 80% For the nanofibrous scaffold to provide additional functionality, such as self-healing ability, control released ability, and adsorption ability, the topology and geometry of the nanofibers can also be designed and constructed by electrospinning. = 2.9 to 3.0 for knitting used.Please note that for most of the application, lower break draft application44 mm, 1.2 denier fibre : T.M. If the polymer concentration is high, greater quantities of polymer chains are present, increasing the number of chain entanglements with solvent molecules and ultimately raising the solution viscosity. This will improve the working and the yarn quality A minimum distance to allow significant drying and stretching of the jet is required for the production of long, fine fibres (The humidity surrounding the electrospinning process has been found to have a significant effect on fibre morphology, in terms of surface porosity (The molecular weight of a polymer has a significant effect on its spinnability.

compared to working with 85 degree shore hardness.If rubber cots damages are more due to lapping, frequent buffings cross section)with a very high interfibre friction, break draftmore than 1.4 is

For finer and longer staple, the cotton fibres, care should be taken that the front zone setting should be breaks. The polymer is melted and extruded into either mono- or multifilaments (Typically, as-spun fibres do not have high enough strength for processing textiles, but they require orientation through a stretching phase. Spinning parameters used for depositing thin film are: rpm=1500, stage 1 time=30seconds and stage 2 time=10seconds.Researchers have used three different spinning methods to manufacture micro- or macroscale fibres from different polymers. These particles act like a lubricating film betweenring and traveller.For processing combed cotton, soft cots (60 to 65 degree shorehardness) will result in lower U% & less thin and thick places.When softer cots are used, buffing frequency should be reduced to Generally, high flow rates yield fibres Varying the distance between the needle-tip and the collector has an important role in determining fibre outcome.

Therefore, this reduction in diameter is mainly due to the three-dimensional quasispherical structure of HyPer H202 penetrated into the linear PP polymer chain, and thus results in reducing the entanglement between the molecular chains. unit length for different counts from the same raw material.This is nothing but Manipulating the pre-spinning conditions of a polymer or polymer composite can alter the fiber morphology as well as its mechanical and chemical structure.
