Description

  The present invention relates to an antistatic woven or knitted fabric and a textile product that have excellent antistatic properties and are less stuffy or sticky.

  Conventionally, as a woven or knitted fabric having antistatic properties, a woven or knitted fabric made of hydrophobic synthetic fibers provided with a treatment containing an antistatic composition by a post-processing method (for example, Patent Document 1), or hydrophilic fibers The thing etc. which comprised the woven / knitted fabric using are known.

  However, the former post-processing method has a problem that the soft texture of the woven or knitted fabric is impaired or the antistatic property is not sufficient. Further, when a woven or knitted fabric is formed using hydrophilic synthetic fibers represented by the latter nylon fibers, chemical fibers such as rayon and acetate, and natural fibers such as cotton, silk, hemp, wool, etc. The garment has the advantage that it has excellent antistatic properties, and also has excellent adsorption and wicking properties of vapor-like sweat, making it difficult for the inside of the garment to be swollen. However, for liquid sweat, the fibers themselves absorb water, so there is a problem that there is a lot of discomfort and cold feeling that the clothes and skin are sticky when sweating a lot.

On the other hand, the present inventors have proposed, in Japanese Patent Application No. 2003-175788, a polyether ester hygroscopic elastic fiber comprising a polyether ester elastomer having polybutylene terephthalate as a hard segment and polyoxyethylene glycol as a soft segment. However, when the woven or knitted fabric is knitted using such a polyether ester hygroscopic elastic fiber alone, the resulting woven or knitted fabric has excellent antistatic properties and good hygroscopicity, but the hygroscopic fibers on the surface of the woven or knitted fabric. It was found that was not sufficient in terms of exposure and stickiness.
