Description
Technical field
The present invention relates to the preparing technical field of cup, specifically a kind of flax fiber cup and preparation method thereof.
Background technology
Flax（Scientific name：Linum usitatissimum L. ）：Annual herb plant, can be divided into fiber with flax,
Oil seed flax and Oil and Fibre Flax three types.Stem is upright, and up to 1.2 meters of height, top is soft, there is wax；Leaf alternate, drapes over one's shoulders needle
Shape, 20-40 millimeters long, 3 mm wides, there is bloom on surface；Colored petal 5,15-25 millimeters a diameter of, blue or white；Fruit is
Capsule, the flat oval of seed like moist climate of feeling nice and cool.
Flax is the natural plant fibre that the mankind use earliest, away from the modern history for having 10,000 years or more.Flax is pure natural
Fiber is increasingly paid attention to by the mankind since it is with absorbing sweat, good air permeability and the distinguishing features such as harmless.
Cup refers to clothes special when women swimming more, and there are also male's cups.Cup is different from gym suit, general to cover
Cup is immersed in the water and will not sink.Cup has single type, bipartial and bikini（Bikini）Deng variation.Initial swimsuit is to be close to
Body hides the big portion's bikini point for wrapping up in body.
