  • Patent number: 4390999
    Abstract: The body bulge controlling portion of the panty hose has elastic yarn incorporated therein to provide a medium amount of compressive force against the body of the wearer and is positioned between portions of the panty hose having a relatively great amount of compressive force and a relatively small amount of compressive force. The compressive force against the body is thereby varied in a stepped or gradual manner so as to eliminate or minimize the abrupt outward bulging of the underlying portion of the body of the wearer. In one embodiment of the panty hose, the body bulge controlling portion is positioned between a panty girdle portion with a great amount of compressive force and the sheer legs which include very little if any compressive force. In another embodiment, the bulge controlling portion is positioned between the elastic waistband and the upper portion of the panty of the panty hose.

  • Patent number: 4057880
    Abstract: The snag resistant leg portion of this hosiery article is knit of a composite self-crimping yarn including a series of mechanical crimps imparted thereto prior to knitting, and a series of crimps imparted to the composite yarn by development of the latent crimp in the composite yarn after knitting. The hosiery article knit of the composite self-comprising yarn having both types of crimp therein has much greater snag or pick resistance than either a hosiery article knit of the same type of composite yarn but including only the crimps imparted by development of the latent crimp in the yarn, or a hosiery article knit of yarn having mechanical crimp only. The knitting of a mechanically crimped composite yarn also produces a normal size greige hosiery article blank which may be processed in the usual manner to produce the finished hosiery article.
