Definitions

  • the present invention relates to a polyester composite monofilament suitable for a mesh fabric used for screen printing. More specifically, it is concerned with a polyester composite monofilament suitable for obtaining high-mesh, high-modulus screen gauze, which requires high precision of electronic circuits and the like.
  • mesh fabrics made of natural fibers such as silk and inorganic fibers such as stainless steel have been widely used as screen fabrics for printing.
  • mesh fabrics made of organic fibers such as nylon and polyester which have flexibility and durability and are dimensionally stable, that is, screen gauze are increasingly used.
  • screen gauze made of polyester monofilament is becoming widespread because it is less affected by moisture and has a lower price than nylon.
  • Japanese Patent Application Laid-Open No. 55-16948 proposes using a high elongation yarn having a breaking elongation of 38 to 60% as a warp.
  • High elongation yarn The use of this means that the draw ratio is set low during the production of the raw yarn, and it is inevitably difficult to obtain a highly modular gauze in the final product.
  • this conventional technique sacrifices the characteristics of high strength and high modulus in order to prevent scum. Therefore, if fine denier is used to obtain higher mesh gauze, the strength will be insufficient, and weaving will be significantly impaired, and a high mesh screen gauze for precision printing will be obtained. It is difficult. Therefore, it is an issue to be solved how a monofilament having a low elongation and a high modulus can be woven while suppressing the generation of scum.
  • Japanese Patent Application Laid-Open No. 62-27648 and International Publication No. WO 88Z06103 disclose printing emulsions, such as nylon, using polyester as a core.
  • a composite monofilament having a sheath made of a polymer that has good adhesiveness to a resin and is durable against abrasion has been proposed.
  • Nylon has the advantage of less shaving compared to polyester and has the ability to prevent scum.
  • Nylon has a high hygroscopicity and has the disadvantage of lacking dimensional stability. In high-precision printing, dimensional stability from the time that the gauze is fixed to the frame to the time it is left to stand, plate making (formation of a printing pattern), and printing is extremely important.
  • nylon When nylon is used, even if it is a part of a composite yarn, it is susceptible to temperature and humidity and tends to reduce the gauze tension. Especially if the atmosphere in the workplace is not strictly controlled, Becomes larger. Therefore, although the weaving property is improved by this technique, the precision of precision printing cannot be improved.
  • low-viscosity polyester is used as a sheath component.
  • low-viscosity polyester is not used as a material for monofilament for screen gauze.
  • the low-viscosity polyester generally means a polyester having a low degree of polymerization, and is liable to crystallize due to heat during stretching of the monofilament, has poor toughness, and tends to be brittle.
  • An object of the present invention is to provide a polyester composite monofilament for a screen gauze that is suitable for precision printing, has good dimensional stability, has good weaving properties, and generates little scum.

That is, when the breaking strength is 6 gd or more, a monofilament of about 9 d can be provided, and when the breaking strength is 7 gZd or more, fineness of up to 7 d can be achieved. Therefore, the breaking strength of the monofilament must be 6 g / d, preferably 7 g / d or more. The higher the breaking strength of the monofilament, the better.
  • polyethylene When terephthalate is used as the core component, the object of the present invention can be sufficiently achieved at about lOgZd or less.
  • the monofilament must have a high modulus.
  • the modulus of a monofilament is the stress that occurs in a yarn at 10% elongation. That is, in the S-S curve of the raw yarn, it means the value obtained by dividing the tenacity corresponding to 10% elongation by the denier. This modulus must be at least 3.5 g Zd, more preferably at least 3.8 g Zd. The higher the modulus of the monofilament, the better.

  • An important feature of the present invention is such a high-strength, high-modulus, low-elongation monofilament, which is devised on how to maintain good weavability. That is, in the present invention, this problem has been solved by using a core-sheath type composite monofilament.
  • a polyester having a low Tg is unlikely to cause scum.
  • a low T g means that a molecular chain forming an amorphous part is easily movable and is closer to a rubber-like state than a glass-like state. In other words, the polymer is soft against abrasion, and it is difficult to scrape.

Therefore, as the sheath component of the present invention, a highly polymerized material having an intrinsic viscosity of 0.60 or more. It is preferable to use a polymer that can be used for spinning.
  • a copolyester having a low Tg is generally soft, but it is difficult to increase the breaking strength and the modulus. Therefore, it is impossible to obtain a monofilament that satisfies the mechanical characteristics of the present invention as it is.
  • this problem has been solved by adopting a composite structure in this regard and disposing a polymer having a low Tg only to the sheath component.
  • a polymer having a low Tg only to the sheath component.

These polyesters have high strength and high elastic modulus, but on the other hand, Lack of flexibility and difficult to follow the warp / weft bending structure when forming high mesh fabrics.
  • a material with a small denier is flexible even if it has a high elastic modulus, and easily follows deformation during weaving.
  • the bundle of fibers becomes flat in the woven fabric, making it difficult to secure the size of the openings in a screen woven fabric and improving the weavability. Heating is required, which not only complicates the process but also lacks uniformity of the openings.

The reason for this is that if the cross section is deformed, hardening of the photosensitive emulsion may cause halation and adversely affect printing accuracy.
