Embodiment Construction

[0008] In the present invention, the cross-section made of PTT is a fiber of unequal length triangle.

[0009] The preferred circular arc transition of the adjacent sides of the present invention, the preferred circular arc of the present invention should not be too large, nor should it be too small, if it is too large, it will affect the difference in orientation, and if it is too small, it will affect the force of the arc portion, so in practice A reasonable choice should be made according to the specific situation.

[0010] According to the above, the purpose of the present invention is to obtain a fiber with a difference in orientation, so other special shapes that meet this requirement are also within the protection scope of the present invention, and the transition of each side can also adopt the arc transition method of the present invention , so that it is not easily damaged while meeting the purpose of the present invention.

Abstract

The invention relates to a strong three-dimensional crimped memory fiber. The fiber is made of PTT (polytrimethylene terephthalate) and has an unequal-length triangular cross section. The fiber has the advantages: 1) the fiber has characteristics of PTT and has the unequal-length triangular cross section, so that the fiber has an orientation difference in a certain direction in a use process, orientates in some direction in the use process and meets service requirements; and 2) adjacent edges are in arc transition, so that a defect of high possibility of damage of the fiber due to bending during extension or compression of the fiber is avoided, the stress at a transition part of the adjacent edges is relatively mild during the extension or compression of the fiber due to the arc transition manner, the excessive stress cannot appear, the fiber is not easy to damage, and the service life of the fiber is prolonged.

Description

technical field [0001] The invention relates to a strong three-dimensional curly memory fiber, which belongs to the technical field of textiles. Background technique [0002] Most of the curly memory fibers that appear on the market are round or regular triangular in shape. This cross-sectional form can reduce the difference in fiber orientation, make all parts of the fiber have the same orientation, and will not be greatly deflected. It is suitable for carpets, etc. The application environment; but in the environment where the orientation needs to be deviated, the above cross-sectional shape obviously cannot be applied well, so it needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a strong three-dimensional crimped memory fiber which can have different orientations and is not easily damaged. [0004] For this reason, the technical scheme adopted by the present invention is: the cross-section made of PTT in the pres...
