Definitions

  • the present disclosure relates to a fiber guide.
  • Fiber guides of various shapes are used in textile machinery to guide fibers. Examples include roller guides, oiling nozzles, rod guides, and traverse guides. There is a demand for fiber guides that have a surface that comes into contact with the fibers (also referred to below as a contact surface) that minimizes damage and fraying of the fibers.
  • Patent Document 1 describes a fiber guide with a surface that comes into contact with the bundles of fed fibers having a surface roughness Ra of 0.1 ⁇ m or less.
  • Patent Document 1 JP-A-2000-73225
  • a fiber guide comprises a contact surface with a fiber with a ratio Ra1/Ra2 of from 0.5 to less than 1.0, where Ra1 is an arithmetic mean roughness in a feed direction of the fiber and Ra2 is an arithmetic mean roughness in an orthogonal direction orthogonal to the feed direction.
  • the fiber guide of an embodiment of the present disclosure can suppress damage to the fibers. Below, embodiments of the fiber guide of the present disclosure will be described with reference to the drawings.
  • the roller guide 10a illustrated in FIG. 1A includes a contact surface that is a U-shaped groove.
  • the roller guide 10a guides a fiber 1 when rotated.
  • the oiling nozzle 10b illustrated in FIG. 1B includes a contact surface that is the bottom surface of a groove. Oil is applied to the fiber 1 when the fiber 1 is slid over the contact surface.
  • the rod guide 10c illustrated in FIG. 1C includes a contact surface that is the outer circumferential surface.
  • the rod guide 10c is used for gathering and separating the fibers 1.
  • the traverse guide 10d illustrated in FIG. 1D includes a contact surface that is the surface of a groove. The feed direction of the fiber 1 that passes along the contact surface is changed so the fiber 1 can be wound around the outer circumference of a cylindrical package.
  • specific fiber guides will not be referred to, and the fiber guide will be denoted with the reference sign 10.
  • the fiber guide 10 includes the contact surface with the fiber 1 with a ratio of Ra1/Ra2 between an arithmetic mean roughness Ra1 (also referred to below simply as Ra1) in the feed direction of the fiber 1 (also referred to below simply as “feed direction”) and an arithmetic mean roughness Ra2 (also referred to below simply as Ra2) in an orthogonal direction orthogonal to the feed direction (also referred to below simply as “orthogonal direction) that is 0.5 or more and less than 1.0.
  • Ra1 arithmetic mean roughness Ra1
  • feed direction also referred to below simply as “feed direction”
  • Ra2 arithmetic mean roughness Ra2
  • orthogonal direction orthogonal to the feed direction also referred to below simply as “orthogonal direction
  • roller guide 10a as an example of the fiber guide 10, the arithmetic mean roughness Ra1 in the feed direction and the arithmetic mean roughness Ra2 in the orthogonal direction will be described with reference to FIG. 2 .
  • feed direction refers to the direction the fiber 1 slides along the contact surface that comes into contact with the fiber 1.
  • Ra1 refers to the arithmetic mean roughness in the feed direction.
  • feed direction can also refer to the rotational direction of the roller guide 10a.
  • orthogonal direction refers to the direction orthogonal to the feed direction of the fiber 1 with respect to the contact surface that comes into contact with the fiber 1.
  • Ra2 refers to the arithmetic mean roughness in the orthogonal direction.
  • the fiber guide 10 having the ratio of Ra1/Ra2 of from 0.5 to less than 1.0, where Ra1 is the arithmetic mean roughness in the feed direction and Ra2 is the arithmetic mean roughness in the orthogonal direction, damage to the fiber 1 can be suppressed. Damage to the fiber 1 can be suppressed because the surface texture of the contact surface of the fiber guide 10 according to an embodiment of the present disclosure is such that the sliding position can change a moderate degree while allowing the fiber 1 to slide with a small contact area and without sliding in the same place.
  • the surface texture of the contact surface with the fiber 1 is identical in the feed direction and the orthogonal direction, or the surface texture in the feed direction is rougher than in the orthogonal direction.
  • the contact surface has such a surface texture, the fiber 1 is likely to jump when sliding, and when the surface texture in the orthogonal direction is flatter than in the feed direction, the fiber 1 is more likely to slide at an angle. This increases the area of contact between the fiber 1 and the contact surface, thus increasing the likelihood that the fiber 1 is damaged by friction.
  • the arithmetic mean roughness Ra1 in the feed direction and the arithmetic mean roughness Ra2 in the orthogonal direction of the contact surface with the fiber 1 can be measured in accordance with JIS B 0601 (2001).
  • An example of measurement conditions may include using a measurement length of from 0.1 to 5.0 mm, a cutoff value of from 0.01 to 0.8 mm, a stylus diameter of from 1 to 10 ⁇ m, and setting the stylus scanning speed to from 0.01 to 1 mm/sec. Measurements are taken at five locations in both the feed direction and the orthogonal direction. The mean of the values obtained from the measurement are taken as the arithmetic mean roughness Ra1 and Ra2.
  • the fiber guide 10 which has the arithmetic mean roughness Ra2 in the orthogonal direction of from 0.03 ⁇ m to 0.05 ⁇ m can further suppress damage to the fiber 1.
  • the fiber guide 10 which has a skewness of Rsk1 obtained from the roughness curve in the feed direction greater than 0 and a skewness of Rsk2 obtained from the roughness curve in the orthogonal direction less than 0 mitigates damage to the fiber 1.
  • Skwness found from the roughness curve is an index representing a ratio between peak regions and valley regions with respect to a central line representing the average height of the roughness. When skewness is a value greater than 0, valley regions are greater than peak regions, and when skewness is a value less than 0, peak regions are greater than valley regions.
  • the area of contact between the two is reduced. This reduces the damage to the fiber 1.
  • skewness obtained from the roughness curve can be measured in accordance with JIS B 0601 (2001), in a similar manner to the arithmetic mean roughness.
  • the fiber guide 10 includes a take-up portion and a let-off portion on the contact surface.
  • an arithmetic mean roughness Ra3 of the let-off portion in the feed direction is greater than an arithmetic mean roughness Ra4 of the take-up portion in the feed direction, damage to the fiber 1 can be further reduced.
  • the fiber guide 10 including a take-up portion and a let-off portion on the contact surface only applies to guides which have a clear distinction between the sides of the contact surface which take up and let off the fiber 1.
  • An example of such a guide is with the oiling nozzle 10b illustrated in FIG. 1B .
  • the contact surface of such an oiling nozzle 10b includes a first end and a second end in the feed direction of the fiber 1.
  • First end refers to the portion of the contact surface on the take-up side that first comes into contact with the fiber 1.
  • “Second end” refers to the portion of the contact surface on the let-off side that last comes into contact with the fiber 1.
  • Take-up portion refers to a portion from the start in the feed direction of the fiber 1 to a position 1/5 the total length, where the total length of the contact surface is from the first end and the second end.
  • Let-off portion refers to a portion from the end in the feed direction of the fiber 1 to a position 1/5 the total length.
  • the fiber 1 is unlikely to jump at the take-up portion, allowing the fiber 1 to be taken up smoothly. Also, the contact area with the fiber 1 at the let-off portion is small, allowing the fiber 1 to be let off smoothly. This further decreases damage to the fiber 1.
  • the arithmetic mean roughness Ra3 and Ra4 can be measured in accordance with JIS B 0601 (2001). First, the take-up portion and the let-off portion of the contact surface are measured in the feed direction at three locations. The mean of the values obtained from the measurement are taken as the arithmetic mean roughness Ra3 and Ra4. Note that the measurement conditions may be the same as that for finding the arithmetic mean roughness Ra1 and Ra2 described above.
  • the arithmetic mean roughness Ra1 in the feed direction increasing in a step-like manner from the take-up portion toward the let-off portion damage to the fiber 1 can be further suppressed.
  • the arithmetic mean roughness Ra1 in the feed direction of the contact surface changes in a step-like manner allowing the fiber 1 to further slide smoothly. This further suppresses damage to the fiber 1.
  • the arithmetic mean roughness Ra1 in the feed direction increasing in a step-like manner from the take-up portion toward the let-off portion means an arithmetic mean roughness Ra7 of the region of the contact surface from the take-up portion to the let-off portion (also referred to below as intermediate portion) in the feed direction is greater than the arithmetic mean roughness Ra4 of the take-up portion in the feed direction and less than the arithmetic mean roughness Ra3 of the let-off portion in the feed direction.
  • the relationship between the arithmetic mean roughness in the feed direction at each location on the contact surface satisfies the following: take-up portion (Ra4) ⁇ intermediate portion (Ra7) ⁇ let-off portion (Ra3).
  • the arithmetic mean roughness Ra1 in the feed direction may also progressively increase from the take-up portion toward the let-off portion.
  • the arithmetic mean roughness Ra7 of the intermediate portion in the feed direction can be measured in accordance with JIS B 0601 (2001), in a similar manner to how the arithmetic mean roughness Ra3 and Ra4 is obtained.
  • the fiber guide 10 with an arithmetic mean roughness Ra5 of the let-off portion in the orthogonal direction being greater than an arithmetic mean roughness Ra6 of the take-up portion in the orthogonal direction can suppress damage to the fiber 1.
  • the fiber 1 is less likely to jump at the take-up portion, allowing the fiber 1 to be taken up smoothly.
  • the fiber 1 is let off, even if the fiber 1 strays to the sides, because the contact area between the let-off portion and the fiber 1 in the orthogonal direction is small, damage to the fiber 1 can be suppressed.
  • the arithmetic mean roughness Ra5 and Ra6 can be measured in accordance with JIS B 0601 (2001). First, the take-up portion and the let-off portion of the contact surface is measured in the orthogonal direction at three locations. The mean of the values obtained from the measurement are taken as the arithmetic mean roughness Ra5 and Ra6. Note that the measurement conditions may be the same as that for finding the arithmetic mean roughness Ra1 and Ra2 described above.
  • the arithmetic mean roughness Ra2 in the orthogonal direction increasing in a step-like manner from the take-up portion toward the let-off portion damage to the fiber 1 can be further suppressed.
  • the arithmetic mean roughness Ra2 in the orthogonal direction of the contact surface changes in a step-like manner allowing the fiber 1 to further slide smoothly. This further suppresses damage to the fiber 1.
  • the arithmetic mean roughness Ra2 in the orthogonal direction increasing in a step-like manner from the take-up portion toward the let-off portion means that the relationship between the arithmetic mean roughness in the orthogonal direction at each location on the contact surface satisfies the following: take-up portion (Ra6) ⁇ intermediate portion (Ra8) ⁇ let-off portion (Ra5). Note that the arithmetic mean roughness Ra2 in the orthogonal direction may also progressively increase from the take-up portion toward the let-off portion.
  • the arithmetic mean roughness Ra8 of the intermediate portion in the orthogonal direction can be measured in accordance with JIS B 0601 (2001), in a similar manner to how the arithmetic mean roughness Ra5 and Ra6 is found.
  • the contact surface of the fiber guide 10 may be made from ceramic.
  • a contact surface made from ceramic has greater abrasion resistance and thermal resistance than contact surfaces made from metal or resin. This allows damage to the fiber 1 to be further suppressed.
  • the ceramic include alumina, zirconia, titania, silicon carbide, silicon nitride, and any composite thereof.
  • a member provided with the contact surface or the fiber guide 10 itself may be made from ceramic, or a base body of the fiber guide 10 may be made from metal or resin and the surface may be coated with ceramic.
  • a member provided with the contact surface may be made from ceramic and this may be joined with a base body made from metal or resin.
  • the material of the contact surface can be identified from the value of 2 ⁇ (2 ⁇ indicates a diffraction angle) obtained by measurement using an X-ray diffractometer (XRD), by using a JCPDS card.
  • alumina (aluminum oxide) powder is added to a mill together with a solvent and balls. This is ground until a predetermined particle size is obtained to make a slurry.
  • a binder is added to the obtained slurry. Then, spray drying using a spray drier is performed to produce granules.
  • the granules are charged into a mechanical press. Pressure is applied to the granules to produce a compact with a predetermined shape. Then, the compact is cut into the shape of the oiling nozzle. Note that the contact surface of the compact cut into the shape of the oiling nozzle has a rougher surface texture in the straight direction than in the feed direction. Alternatively, an injection molding method using pellets made from the same raw material may be used to produce the compact.
  • the obtained compact with the oiling nozzle shape may be fired for 1 to 8 hours in an atmosphere kept at a maximum temperature of from 1450 to 1750°C. Note that the firing conditions for the maximum temperature and the duration kept at a particular temperature can be adjusted as necessary depending on the size and shape of the article.
  • the obtained sintered compact with the oiling nozzle shape is fixed in place, and the contact surface of the sintered compact is finished by sliding a cord over the contact surface of the sintered compact at a feed rate of 300 m/min while supplying the contact surface with oil in which abrasives are dispersed.
  • the cord used in this finishing may be a nylon cord with a diameter from 0.5 to 10 mm, and the abrasives used may be diamond abrasive grains with an average particle size of from 2 to 6 ⁇ m.

  • the cord is preferably slid over the contact surface while the sintered compact with a roller guide shape is rotated.
  • the contact surface is finished by the cord being slid over the surface in the feed direction of the fiber 1.
  • the surface roughness of the contact surface in the orthogonal direction is made less than that in the feed direction.
  • the oiling nozzle 10b After finishing the contact surface for from 3 to 20 minutes as described above, the oiling nozzle 10b according to an embodiment of the present disclosure with the ratio Ra1/Ra2 between the arithmetic mean roughness Ra1 in the feed direction and the arithmetic mean roughness Ra2 in the orthogonal direction being from 0.5 to less than 1.0 is obtained.
  • the period of time the contact surface is finished as described above can be set to from 5 to 10 minutes.
  • abrasives used in the finishing of the contact surface as described above may have an average particle size of from 2 to 4 ⁇ m. In such a manner, by using abrasives with a small particle size, the contact surface is finished in a scratching manner in the feed direction. This allows the skewness Rsk1 to be kept greater than 0 while only making the skewness Rsk2 further below 0.
  • the arithmetic mean roughness in the feed direction and the orthogonal direction at each location can be made a discretionary value.
  • the manufacturing method employed may be similar to that for the oiling nozzle 10b described above except for the shape of the guide.
  • Roller guides with different ratios Ra1/Ra2 between the arithmetic mean roughness Ra1 in the feed direction of the contact surface and the arithmetic mean roughness Ra2 in the orthogonal direction of the contact surface were manufactured. Fibers were guided with the roller guides and the time taken until the fibers were damaged was compared.
  • alumina powder of 99.6% purity was added to a mill together with water (solvent) and balls, and the mixture was ground to produce a slurry.
  • a binder was added to the slurry. Then, spray drying using a spray drier was performed to produce granules. The obtained granules were charged in a mechanical press and compacts were produced. The compacts were cut to obtain compacts with a roller guide shape.
