  • the high density woven fabrics, surface-coated and calendered woven fabrics usually have a low softness (a hard hand), and the surfaces of the fabrics exhibit a low resistance to abrasion (abrasion resistance, and thus these types of woven fabrics must be improved.
  • Synthetic fibers for example, polyester and polyamide fibers have excellent physical and chemical properties and thus are practically used in various uses such as clothing and industrial uses.
  • the polyester fibers exhibit excellent mechanical strength, dimensional stability and an easy-care property, and thus various types of woven fabric formed from synthetic fibers, for example, polyester fibers, are used widely.
  • the woven fabrics formed from synthetic fibers such as polyester fibers have, in addition to the above-mentioned advantageous properties, a high transparency.

  • inorganic fine particles for example, titanium dioxide particles are distributed into the synthetic fibers.
  • This means can cause the resultant synthetic fibers to exhibit an increased opacity and thus an enhanced see through-preventing property.
  • the woven fabric formed from the opaque synthetic fibers still must have an increased weave density to prevent the transmission of light through gaps formed between the yarns from which the woven fabric is formed. This increase in the weave density causes a problem that the resultant woven fabric exhibits a decreased softness.

  • the above-mentioned light-blocking fabric having a black-colored light-blocking layer formed on a fabric surface and light-blocking curtain have a problem that as the light-transmitting property is poor, the inside of the curtained room is dark and an oppressive atmosphere is created in the curtained room. Also, the light-transmitting property of the mirror curtain is high. However, the mirror curtain has a problem that the vision through-preventing property of the mirror curtain, particularly in might time, is insufficient, and the sheeting gloss yarns cause a garish gloss, on the mirror curtain, to be created.
