Definitions

  • PAPER TUBE BOBBIN FOR TREATMENT OF YARN IN CHEESE FORM Inventors: Miyaji Ito, Takatsuki-shi, Osaka;
  • This bobbin has grooves or one slit running along the length of the tube.
  • This paper bobbin can be used for heat-treatment of yarn in cheese form. It collapses and contracts in its periphery length when a cheese is heated. The pressure caused by thermal shrinking of wound yam causes the paper tube to collapse with ease.
  • the collapsed shape of the paper tube in a cheese is round or heart-like;
  • FIG. 3A MASAO UMEZAWA, TADASHI FURUKAWA, HIROO HIRAKO PATENTEDSEP 4191s SHEHZBFZ.
  • the present invention relates to a paper tube bobbin used for heat-treatment of yarn in a cheese form.
  • a paper tube bobbin used for heat-treatment of yarn in a cheese form.
  • Heat-treatment of yarn in hank can surely be expected to produce the balanced effect of heattreatment.
  • the increase of equipment and workers for processes before and after the heattreatment can not be avoided.
  • this procedure is apt to distort and entangle the yarn and cause breakage of yarn in rewinding, knitting and weaving. It also spoils the quality of the final product.
  • a metallic bobbin tends to corrode by hot water or steam, and has inevitably to be of complex structure and is inconvenient for use. Another defect of a metal bobbin is that it is too expensive to throw it away after it is used.
  • a bobbin made of synthetic resin tends to undergo a change in its form by heat and pressure applied during heat-treatment.
  • the distortion of and permanent defor mation of a synthetic resin bobbin made it difficult to reuse the bobbin. Irregular deformation of the bobbin reduces efficiency of the rewinding process and other forwarding process after the heat-treatment and spoils the quality of treated yarn.
  • a paper bobbin has a tubular structure.
  • a paper tube bobbin of thin paper collapses easily with the shrinking of yarn layer.
  • Paper is not expensive material for making a bobbin compared with metal or plastics material, and has a proper solidity and elasticity.
  • the shape of the collapsed bobbin is not almost circular but irregular and serrated, it will cause entanglement of in a cheese, and cause breaking of yarn in the rewinding process. It is confirmed by our study that to make a paper tube bobbin thinner only in order to make it collapse to a uniform shape in a cheese is not sufi'icient to make a good bobbin.
  • the object of the present invention lies in presenting a novel paper tube bobbin for heat-treatment of yarn in cheese form, and to show the way to use such paper tube bobbin.
  • the present invention offers a profitable method for thermosetting twisted yarn and for heattreatment or bulking of spun yarn, textured yarn and filamentary yarn.
  • the present invention also aims at simplification of yarn processing and accomplishing the production of yarn with better yarn quality.
  • the present paper tube bobbin can be thrown away after use.
  • a paper bobbin comprises a cylindrical or tubular structure made of formed paper material which has a narrow groove or a plurality of grooves or an oblique cut slit running straight along the length of said structure, and the outer surface of the I structure is covered at least over the vicinity of said groove or slit with thin paper.
  • This paper tube bobbin collapses easily at the notch or at the slit and shortens its circumference receiving the pressure caused by the shrinkage of heat-shrinkable yarn wound on it when heat-treated.
  • the shapev of the collapsed bobbin is mostly heart-shape or round-shape.
  • the form of collapsed structure like this has substantially no irregular indented shape over the outer circumference of the paper bobbin when collapsed.
  • the inner layer yarn is hardly disturbed because of the simple shape of the collapsed bobbin in spite of the collapse of a part of the bobbin itself.
  • Thin paper covering the surface of the tube structure is not stuck with paste around the slit or groove.
  • a preferable thickness of thin paper is 0.05 0.2 mm., considerably thin compared with the thickness of the bobbin.
  • kraft paper is suitable.
  • the size of paper tube bobbin can be determined in accordance with the amount of yarn taken up, bobbin holder of winder and the width of traversing of winder. In case the amount of yarn is 300 g 2,000 g, a diameter of the outer circumference of the bobbin is 40 mm mm and the length of it is 5 l0 inches.
  • the thickness of paper constructing the cylindrical structure relates to a diameter of the paper tube bobbin and 1.00 mm 4.00 mm is appropriate.
  • a preferable thickness is determined by the quality of paper material and percentage of thermal shrinkage of yarn.
  • the depth of the groove should be between one third to four fifths of the thickness of the paper material. Width of the groove is preferably less than 5 mm.
  • the ideal size of a diameter in a collapsed state after heat-treatment is arithmetically calculated referring to the percentage of shrinkage of yarn in boiling water. In the drawing, model pictures and important structure of the present bobbin parts are emphasized more or less.
  • FIG. 1A represents a cylindrical ortubular form used for a base structure for making a paper tube bobbin.
  • FIG. 2A represents an example of the present invention showing a slit cutting across obliquely to the diameter of the cylindrical structure.
  • FIG. 2B is a top viewof thecylindrical structure of FIG. 2A.
  • FIG. 2C shows the cylindrical structure a collapsed condition.
  • FIGS. 3A, 3B, and 3C show different embodiments of the bobbin.
  • FIG. 3A shows an embodiment in which the bobbin has a part of its surface adjacent the slit covered with paper.
  • FIG. 3B shows another embodiment in which the bobbin has its entire surface covered with paper.
  • FIG. 3C shows another embodiment in which the bobbin has its surface covered with one kind of paper of FIG. 2A in and the faces of the slit covered with a different kind of paper.
  • FIG. 3D shows the bobbin of FIG. 3B in a collapsed condition.
  • FIG. 4A shows the shape of the bobbin with yarn wound thereon prior to heat treatment.
  • FIG. 4B shows the same bobbin collapsed after heat treatment.
  • FIGS. 1A and B represent a shaped cylindrical structure made of a thick paper.
  • the cyrindrical or tubular structure a is a round shape with a hollowed part b.
  • This structure has a shape just like what has usually been used as a paper tube bobbin for taking up of the yarn.
  • the spindle of a take-up winder is inserted into the hollowed part to wind up yarn.
  • FIGS. 2A, 2B and 2C An example of the present paper tube bobbin is shown in FIGS. 2A, 2B and 2C.
  • Characteristic feature of this example is a slit cutting obliquely across the thickness of the tubular structure running straight along a supposed longitudinal axis in length wise direction as shown in FIGS. 2A & B. If heat-shrinkable yarn wound on this paper tube bobbin is treated with heat, one edge of the slit slides into the other edge along the cut face, and shortens the outer circumference of the bobbin which remains nearly round in shape. This type of collapse causes the least disturbance of yarn.
  • FIGS. 1 An example of the present paper tube bobbin is shown in FIGS. 2A, 2B and 2C.
  • Characteristic feature of this example is a slit cutting obliquely across the thickness of the tubular structure running straight along a supposed longitudinal axis in length wise direction as shown in FIGS. 2A & B. If heat-shrinkable yarn wound on
  • FIGS. 2A, and 2B are a perspective view and cross section view of a tubular structure with a slit f which is cutting the tubular structure across the thickness in an oblique manner.
  • a slit f is cut along the length of paper cylinder, crossing the thickness of the cylinder obliquely to the diameter of the round-shaped section of the cylindrical structure. Accordingly, the edge g is adjacent to the edge h at the slit section with faces neatly contacted.
  • FIG. 2C shows the collapsed structure after use. Edge 8 slides inside edge h and the outer circumference contracts in a nearly round manner by the pressure caused by the shrinking of yarn layer.
  • An appropriate angle of inclination of the slit cutting the thickness of the structure is between 30 to 60 to the diameter of the cylindrical structure. If a thin paper p of a kind different from kraft paper constructing cylindrical structure is put between two faces of the edges of the slit, as shown in FIG. 3C or if both edges are coated with silicon, teflon, the edges can slide more smoothly. Covering the slit with thin paper like kraft paper prevents the disturbance of inner layer yarn as shown in FIG. 4A and 4B.
  • FIGS. 3A & B the whole or a part of surface of the tube structure is covered with kraft paper p stuck with paste except at least the surface i (diameter X percentage of shrinkage X 3 X 56) of one edge g which slides inward the bobbin. j is the pasted part fixing the paperon the tube structure.
  • FIG. 3(C) shows a tube structure wherein the outside paper covering extends beyond one edge which will facilitate movement during heat treatment of the wound yarn.
  • FIG. 3D shows the section of the collapsed tube of FIG. 3B.
  • part i where thin paper is not stuck is to decrease resistance against the contraction of the circumference and to be efiective for bobbin to contract keeping a round shape when the outer circumference shortens with the heat-treatment of the heatshrinkable yarn wound on the paper tube bobbin as stated before. Therefore, this makes rewinding quite easy without any disturbance of yarn layers.
  • the cylindrical structure or tube structure of the present invention consists of paper material made from natural or synthetic fiber.
  • Such fiber material may be waste paper, wood pulp, bamboo pulp, cotton linter, fibrous flakes, non-woven fabric, sliver of fibrous material, pieces of regenerated paper and the like.
  • As the methods of making the bobbin such the following generally-known methods can be named; to roll a thick paper and fix the shape, to pile adequate sheets of thin paper and fix the shape with starch, or to mix the shredded pieces of fiber material or waste paper with size (e.g. starch, C.M.C., P.V.A., glue, etc.) and pour the mixture into a mold to be dried up.
  • the last named method of using a mold is the most simple and cheapest. This method is advantageous because the compression strength of the tube can be choosen from a wide range.
  • paper tube bobbin of the present invention is effective in twist setting of yarn made of any fibers. It can also be applied to heat treat the heatshrinkable yam made of synthetic fiber materials in the fonn of cheese. For example, bulking of spun yarn of acrylic fiber or thermo-setting of textured yarn can be accomplished with low processing cost without spoiling the yarn quality. As a result, supply of bulky yarn for fabric making factory and dyeing factory is streamlined and heat-treatment of yarn without hank reeling process realized.
  • bulking of spun yarn at spinning mill can be performed economically by taking up to the collapsible bobbin of this invention, and after cheesing up,
  • collapsible bobbin of the present invention makes it possible for yarn to be processed in a cheese form throughout spinning, dyeing, and finishing processes, thereby lowering of the processing cost due to ommission of some preparatory work can be accomplished.
  • Example 1 800 g of spun yarn of 1/60 (Nm) which is of 100 percent acrylic fiber having 25 percent of shrinkage by 100C steam treatment was wound up on a collapsible paper tube bobbin and prepared a cheese with wound density of 0.24 g/cm.
  • the paper tube was prepared by shaping a paper tube structure and cutting a slit along its entire length direction, the slit cutting across the thickness of the tube structure with an angle of 55 to the diameter of the tube structure.
  • the outer diameter of the tube structure was mm, the length 172 mm,
  • the winding speed was 450 m/min. and winding density was 0.18 g/cm with wound weight of 800 g.
  • 100 kg yarn per one dyeing lot was dyed to a dark, or a middle, or a light color, totaling in weight tons.
  • the cones were dried, Milano rib stitch were knit with the tubular knitting machine of 18 06. by supplying directly from the dyed cone.
  • Hank dyeing process needs 884 workers for 8 hours per day work, while the method of the present invention 584 workers for the same hours. This shows how the necessary labor can be reduced as compared with the conventional method.
  • Example 2 Acrylic filament yarn of 200 denier/68 filaments with 12.5 percent shrinkage by 110C steam was wound on a collapsible paper tube bobbin, made mainly of cellulose, having the thickness of 1.5 mm, the outer diameter 70mm, and the length 220 mm.
  • a slit line whose angle to a tangent line of the outer circumference of the structure was 40, was running along the longwise side, and the surface of the paper tube structure was covered with 0.03 mm paper, stuck with paste except the both sides of said cutting line by 2 cm in width.
  • 1,000 g per bobbin of said yarn was taken to a cheese with 0.45 g yarn/cm density. Then the cheese was treated with steam of 110C for 20 minutes, and the percentage of shrinkage was measured.
  • the percentage of shrinkage of the inner, middle, and outer layer were 12.5 percent, 12.7 percent and 12.4 percent respectively.
  • the shrinkage of yarn was almost the same value.
  • the paper bobbin contracted to almost a round shape in cross section with about 60 mm in circumference and no disturbance of the inner layer yarn was observed.
  • Example 3 The. same collapsible paper tube bobbin as that of Example 2 was used.
  • the yarn was of polyester filaments denier/40 filaments, (percentage of shrinkage by hot water was 13 percent).
  • the yarn weighting 800 g was wound on a cheese with 0.55 g/cm of density.
  • the cheese was treated with steam at C for 20 minutes.
  • the shrinkage of the yarn, of the inner, middle, and outer layers of the cheese was 12.2 percent, 12.1 percent, and 12.2 percent respectively.
  • the paper bobbin contracts to an almost round shape with 55 mm diameter on an average without disturbance of the inner layer yarn.
  • the yarn of the inner, middle, and outer layers was knit alternatively, and then was dyed with Foron Navy S-GL (Sandoz) 3 percent owf at 100C for 60 minutes. There were no appreciable color differences among the inner, middle, and outer layer sample yarns when obserbed with the naked eyes. Accordingly, heat setting of polyester filament yarn was attained uniformly by steaming a cheese with use of the collapsible paper tube bobbin of the present invention.
