A stretchable high density woven fabric showing a cover factor of from 1,800 to 2,540 and stretchability in terms of a stretch ratio of from 5 to 20% in the warp or weft direction and having a poly(trimethylene terephthalate) fiber at least in the direction in which the woven fabric shows stretchability. The high density woven fabric shows good stretchability and water resistance (water pressure resistance), produces less rustling when contacted with woven fabrics, and provides an excellent soft and comfortable feeling, and it is therefore appropriate for sportswear, outerwear, and the like.

A multilayer fabric including a plurality of layers of distinct fabrics each consisting of ground warps, ground wefts, connecting warps connecting the layers of the distinct fabrics, and temporary wefts which can be broken by external action after weaving. These temporary wefts are, for example, made of weaker yarn compared with the other yarn, so when the external action is applied to the multilayer fabric, there is no chance of damaging the connecting yarn. Thus, the multilayer fabric can easily be expanded to a large thickness. Also, a fabric form made of the multilayer fabric and composite structure made of the fabric form and filling matter.

A filter medium comprising one fibrous web or a plurality of piled and integrated fibrous webs is provided. The web or webs are composed mainly of ultra-fine combustible synthetic fibers having a single fiber diameter of 0.1 to 1.5.mu.. The constituent fibers in each web are entangled with one another in various directions and satisfy the following requirements:
