Description
Technical field
The present invention relates to underwear and underpants technical field, and in particular to a kind of comfortable buttock lifting underpants.
Background technology
Underpants are the personal clothing of women, and the significant points to women play very strong protective effect.But with the epoch
Development, requirement of the women to underpants also more and more higher, the style of underpants and item are also more and more.
Cause present women not know how to select suitable underpants, or even ignore for simple attractive in appearance and function
Most basic comfortableness.Especially present women pursues beauty of line, increasingly likes wearing the buttock lifting underpants of close-fitting vest, in order to reach
Preferable hip-lifting effect, general buttock lifting underpants are all made of to use this material with elastomeric property of polyurethane fiber, but
It is the soft coarse of polyurethane fiber, the friction to skin is big.In addition, the gas permeability and hygroscopicity effect of polyurethane fiber compared with
Difference, long-term dress can influence the healthy reproduction of women.
And comfort level most preferably pure cotton underpants at present, can only be as typically but the hip-lifting effect of the underpants of pure cotton is poor
Underpants dress, do not possess hip-lifting effect.
The content of the invention
In order to overcome shortcoming and defect present in prior art, it is an object of the invention to provide in a kind of comfortable buttock lifting
Trousers, it has comfort level high, and soft, hip-lifting effect is good, the characteristics of good permeability.
The purpose of the present invention is achieved through the following technical solutions：
A kind of comfortable buttock lifting underpants, anter and rear panel, provided with bottom shelves between anter and rear panel, the rear panel is symmetrically arranged with
Buttock lifting portion, the lower end of the rear panel is provided with leg portion, and the surface in leg portion and the buttock lifting portion is equipped with the elastic glue-line of buttock lifting, institute
The elastic glue-line of buttock lifting is stated to be made up of the raw material of following parts by weight：
