Attorney:  Koichi Mizukuchi,Agent  \n# Simple Explanation of the Figures\n\nFigure 1 shows a specific example of the orifice shape on the spinneretof this invention.Figure 2 shows an enlarged cross sectional view of thelinear material obtained by spinning through aforementioned spinneret.Detailed Description of the Invention  \nThis invention deals with a spinneret for the production of a beautifulnovel linear material with a silky gloss equipped with four indentations alongthe fiber axis made from fiber forming starting materials which can be melt  \nspun such as polyamides,polyesters or inorganic glass.  \nIn order to impart favorable pro perties to the fibers used to weavecloths,various cross sectional shapes for the fibers have been used.  \nFor example,U.S.Patent No.2939201 presents a filament with atriangular cross sectional shape with three indentations along the fiber axis.The patent claims that the said filament has a unique glossy look called\"1uster high light\"and is useful in pre paring fabrics with improved soilresistan ce.Similarly,fibers with ribbon shaped,dog bone shaped or crossshaped horizontal cross section have been introduced to improve the propertiesof the fabrics.  \nHowever,none of the horizontal cross sectional shapes known in the priorart can be said to impart all the desirable properties to the final fabricproduct suf ficiently.In other wor ds,the aforementioned triangular shapedfilament is too shiny and lacks the elegance and the silky luster.Thus,theproduction of a linear material with a silky luster and the elegance of silkwill be a significant advancement especially in the clothing field.  \nIn preparing fibers with unusual horizontal cross section describedabove,theshape of the orifice corresponding to the horizontal cross sectionof the prior art is combined with a linear slit or an orifice with a shapesuch as triangle is used for spinning.Howe ver,such orifice is difficult toprepare technically and it tends to cause plugging of the fine nozzle.Thus,the modification of the existing orifice has not been completely satisfactory.Furthermore,the melt spun fiber spun from triangular or square shaped orificetends to become roun ded out by the action of the sur face tension of theun solidified filament.Thus,it is impossible to obtain a linear materialwith sufficient indentations or grooves along the filament axis by thisapproach.  \nU.S.Patent No.2831748 presents a porous plate equipped with orifices  \nhttps://archive.org/details/spinneretforprod00ueda  \neach consisting of several circular holes slightly overlapping with eachother.this invention used this plate as a spinneret for the melt spinning ofcellulose acetate.None of the suggested orifice was successful in presentinga linear material equipped with four symmetrical indentations or grooves alongthe direction of the fiber axis.  \nThe objective of this invention is to provide a linear material equippedwith four symmetrical groo ves along the lengthwise direction having a suitabledegree of shine and elegant and silky beautiful gloss.This linear materialis particularly designed for knitted fabrics.  \nThe aforementioned objective is achieved by a spinneret for theproduction of a linear material having a","cbCailGpt4kf2Rwe","https://ap.wps.com/l/cbCailGpt4kf2Rwe","pdf",703962,"English","# Simple Explanation of the
