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
The present invention relates to a kind of powerful three-dimensional crimp memory fiber, belong to textile technology field.
Background technology
The curling memory fiber that existing market occurs is mostly circular or in rule triangle, and this kind of section form can make fiber-wall-element model difference diminish, and makes each portion of fiber towards unanimously, and very large deflection can not occur, and it is applicable to the applied environments such as carpet; But needing the environment towards deviation to some extent, above-mentioned cross sectional shape obviously can not well be applied, therefore need to improve.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide one can have orientation difference, and a kind of powerful three-dimensional crimp memory fiber of fiber not easy damaged.
The technical solution used in the present invention is for this reason: the cross section that the present invention is made up of PTT is the leg-of-mutton fiber of Length discrepancy.
The cross section of being made up of PCT, PTT is the leg-of-mutton fiber of Length discrepancy.
Described adjacent edge arc transition.
Advantage of the present invention is: 1) the present invention utilizes the characteristic of PTT, fibre section being made cross section is Length discrepancy triangle, such fiber in use has orientation difference in a certain direction, and it in use towards some directions, can meet instructions for use; 2) adjacent edge is arc transition by the present invention, such fiber is when receiving stretching or compression, avoid the defect making its easy damaged due to turnover, the mode of arc transition makes it when being stretched or compress, the transition position of adjacent edge is stressed comparatively to be relaxed, there will not be the situation that stress is excessive, thus it is not easily damaged that fiber of the present invention is had, and improves its service life.
Detailed description of the invention
The cross section that the present invention is made up of PTT is the leg-of-mutton fiber of Length discrepancy.
Preferred adjacent edge arc transition of the present invention, the present invention's preferred circular arc degree is unsuitable excessive, also unsuitable too small, and crossing conference affects orientation difference, too small, can affect the stressed of arc sections, therefore should reasonably select as the case may be in actual time.
Described in upper; the present invention is to obtain a kind of fiber possessing orientation difference; therefore these other abnormity required are met also in protection scope of the present invention; the transition position on its each limit also can adopt arc transition mode of the present invention; to make it while meeting the object of the invention, there is the feature of not easy damaged.
Claims (3)
