- the yarn (2) has a relatively low water-absorbing self-elongation rate, but is a low-water-absorbing self-extensible yarn that does not substantially exhibit elasticity.
- the yarn (3) is a low water-absorbing self-extensible yarn having relatively low water-absorbing self-elongation and elasticity, and having a cut elongation of 30% or more.
- Each of the yarns (1), (2) and (3) is wound around a skein frame of 1.125 m with a load of 0.88 mN / dtex to form a skein of 10 turns.
- Remove the skein from the skein frame leave it in an air environment with a temperature of 20 ° C and a relative humidity of 65% for 24 hours to adjust the condition, and apply a load of 0.0088 mN / dtex to the dried skein.
- the wet yarn length (Lw, mm) is measured, and the following formula is obtained:
- the yarn (1) has a water absorption self-elongation of 5% or more, and the yarns (2) and (3) have a water absorption self-elongation of less than 5 ⁇ 1 ⁇ 2,
- a water-absorbing self-extensible, stretchable composite yarn (A) is formed from the yarn (1) and the yarn (2), and the yarn (3) is a non-water-absorbing self-extensible material having substantially no self-extensibility.
- the woven and knitted fabric contained in the elastic yarn (B) is dimensionally stabilized in an atmosphere having a temperature of 20 ° C and a relative humidity of 65%, A test piece of the composite yarn (A) having a length of 30 cm was collected from the fabric, and a load of 0,0088 mNZdte X of the yarn (1) and the yarn (2) in the test piece was measured.
- the ratio L 1 ZL 2 Value is less than 0.9
- the stretchable composite fabric has a woven structure, and in the warp group and / or the weft group in the woven structure, the water-absorbing self-extensible stretchable yarn (A) and the non-water absorbing It is preferable that one or more self-extensible and elastic yarns (B) are alternately arranged.
- the composite yarn (A) and the yarn (B) force constitute only one of the warp group and the weft group in the woven fabric, and the other yarn group. Is preferably composed of one or more yarns different from the composite yarn (A) and the yarn (B).
- the yarn different from the composite yarn (A) and the yarn (B) is a yarn composed of a plurality of single fibers having a flat cross-sectional shape and a yarn having a diameter of 1.5 dtex or less. It is preferable to be selected from a yarn composed of a plurality of single fibers having fineness.
- the composite fabric has a multilayered structure of two or more layers, and at least one layer of the multilayered structure has a content of 20% by mass or more of the total mass of the composite yarn.
- at least one other layer of the multilayered structure contains (A) and the yarn (B) at a content of 20% by mass or more of the total mass.
- the fibers constituting the highly water-absorbing self-extensible and stretchable yarn '(1) contained in the composite yarn (A) are made of a hard segment comprising a polyethylene terephthalate block. It is preferable to be selected from polyetherester fibers formed from a polyetherester elastomer that contains a polysulfone and a soft segment comprising a polyoxyethylene glycol block.
- the fibers constituting the low water-absorbing self-extensible / non-stretchable yarn (2) contained in the composite yarn (A) are preferably selected from polyester fibers.
- the fibers constituting the yarn (2) have a single fiber fineness of 1.5 dtex or less.
- a composite including another yarn (4) in addition to the low water-absorbing self-stretchable / stretchable yarn (3) in addition to the non-water-absorbing self-stretchable / stretchable yarn (3)
- the yarn may be used.
- the fibers constituting the yarn (3) having a breaking elongation of 200% or more are a hard segment comprising a polybutylene terephthalate block, and a polytetramethylene salt. It is preferable to be selected from polyetherester fibers formed from a polyetherester elastomer containing a xidoglycol block strength and a soft segment.
