Abstract: PROBLEM TO BE SOLVED: To obtain a composite covered elastic yarn not causing the phenomenon of exposure of core yarn and to provide a method for producing the same. SOLUTION: This bulky conjugate elastic yarn Z has a yarn structure obtained by coating the circumference of an elastic yarn 1 of a core yarn with a multifilament false twist yarn 2 in a substantially twistless manner to constitute a false twist covered elastic yarn Y of twistless covered structure and further substantially interlacing the circumference of the false twist covered elastic yarn Y with a filament yarn or a stable fiber yarn X. The elastic yarn is arranged in parallel with the multifilament yarn and subjected to false twisting to produce the false twist covered elastic yarn and the circumference of the false twist coated elastic yarn is subjected to interlacing treatment with the filament yarn or the stable fiber yarn to give the objective composite covered elastic yarn.

SOLUTION: This composite covered elastic yarn Z is composed of a yarn structure obtained by covering the circumference of an elastic yarn of a core yarn with a multifilament false twist yarn 2 of a sheath yarn in a substantially twistless manner to constitute a false twist covered elastic yarn Y of twistless coating structure and winding the circumference of the false twist coated elastic yarn Y with a filament yarn or a stable fiber yarn by twisting. The elastic yarn is arranged in parallel with the multifilament yarn and subjected false twisting to produce the false twist coated elastic yarn and the circumference of the false twist coated elastic yarn is wound with the filament yarn or the stable fiber yarn by a covering processing or a doubling processing to give the objective composite covered elastic yarn.

Abstract: PROBLEM TO BE SOLVED: To prepare a windbreaker having excellent ventilation even in the case of wearing in which the foot of the windbreaker is put inside lower clothes. SOLUTION: An air passing opening 2 at the upper part of the front body 1 is made larger than an air passing opening at the upper part of the back body, preferably 1.1-2 times. Plural covering cloths are sown in a state in which they cover an air passing opening and a part of the opening is remained uncovered. The openings 6a, b of the front body are formed in the ranges of 3-25% and 40-75% of the dress length L1 from the neck point 7, and the openings 6c, d of the back body are formed in the ranges of 0-30% and 45-65% of the dress length L1 from the neck point 7. It is preferable to make openings slantwise since the ventilation is accelerated. It is also preferable that the lower end 9 of the air passing opening of the front body is placed in the range of 40-75% of the dress length L1 from the neck point 7, and that 10 of the air passing opening of the back body is placed in the range of 45-65% of the dress length L1 from the neck point 7, covering the entire width of the bodies.
