Definitions

  • the present invention relates to a woven fabric and articles made of the same. More specifically, it relates to a woven fabric for use as covers such as a building material cover, etc., sheets such as a waterproof sheet, etc., or sheet-shaped materials such as a tent, a packaging bag, a flexible container, etc., and articles made of the same.
  • a sheet-shaped woven fabric is produced by weaving fiber bundles obtained by sizing multifilaments, and for the weaving, the treatment of the multifilaments to cause an oil (antistatic agent) to adhere to their surfaces and the twisting of the multifilaments are essential.
  • the twisting is carried out, however, fiber bundles in a woven fabric are liable to be non-uniform, and as a result, it has been difficult to obtain a woven fabric having excellent properties, in particular, high tensile strength and a low elongation percentage.
  • the woven fabric surface is treated to impart it with water repellency.
  • the thus-obtained waterproofing woven fabric has a problem that it suffers absorption of water into between monofilaments and infiltration of water into end surfaces or damaged portions of the woven fabric.
  • each multifilament is treated to impart it with water repellency as is found, for example, in a base fabric formed of polyethylene terephthalate (PTE) fibers obtained by using a fluorine-containing water repellent as a spinning oil (for example, see JP-A-6-136622 ) or in the treatment of a fiber bundle formed of polyester-based fibers constituting a base fabric of tarpaulin with an emulsion that mainly contains a fluorine-containing water repellent and a polyester-based urethane (for example, see JP-A-7-173774 ).
  • PTE polyethylene terephthalate
  • the present inventors had made diligent studies and as a result it has been found that the above object can be achieved by a woven fabric obtained from a fiber-reinforced thermoplastic resin linear material formed by drawing non-twisted sheath-core type bicomponent-spun fibers whose sheath component is a thermoplastic resin having a lower melting point than its core component by 20°C or more, under specific conditions.
  • the present invention has been completed on the basis of the above finding.
  • the present invention provides
  • a woven fabric having excellent properties such as high tenacity, a low elongation percentage, etc., and having an excellent waterproofing property while maintaining the excellent properties and a woven fabric finished article thereof.
  • the woven fabric of the present invention is a woven fabric produced from a fiber-reinforced thermoplastic resin linear material formed by drawing sized (bound) sheath-core type bicomponent-spun fibers at a temperature that is equivalent to, or higher than, the melting point of a sheath component but lower than the melting point of a core component to melt-fuse the sheath components.
  • the core component (high melting point component) in the above sheath-core type bicomponent-spun fiber can be selected from a crystalline propylene polymer, crystalline polyesters such as polyethylene terephthalate and polybutylene terephthalate, a polyamide (nylon), an aromatic polyester resin (liquid crystal polymer) or the like, and these may be used singly or in combination.
  • a crystalline propylene polymer that is a like polyolefin resin is preferred when recyclability is taken into account.
  • an isotactic polypropylene resin is preferred.
  • the Q value weight average molecular weight/number average molecular weight, Mw/Mn
  • the melt index MI temperature 230°C, load 2.16 kg
  • IPF is less than 85 %, the steric regularity is insufficient, the crystallinity is low and an obtained linear material is poor in physical properties such as strength.
  • the above polypropylene resin may be a homopolymer of propylene or may be a copolymer of propylene and ⁇ -olefin (ethylene, butene-1 or the like).

  • ⁇ -olefin such as butene-1 or the like.
  • thermoplastic resin having a lower melting point than the above core component by 20°C or more is used.
  • This thermoplastic resin includes various olefin polymers and a low-melting-point polyethylene terephthalate.
  • olefin polymers examples include ethylene polymers such as high-density, medium-density and low-density polyethylenes and linear low-density polyethylene, copolymers of propylene and other ⁇ -olefins, specifically such as a propylene-butene-1 random copolymer and a propylene-ethylene-butene-1 random copolymer, non-crystalline propylene polymers such as soft polypropylene, and poly(4-methylpentene-1). These olefin polymers may be used singly or may be used in combination.

  • the method for the above drawing may be any method so long as a desired fiber-reinforced thermoplastic resin linear material can be obtained, and it is hence not specially limited. However, it is preferred to draw the above sheath-core type bicomponent spun fiber in a pressurized saturated steam since in this case a fiber-reinforced sheath-core type thermoplastic resin linear material having excellent properties can be obtained.
