Description
Technical field
It the utility model is related to fibre technology field, and in particular to a kind of fire-retardant high-shrinkage fiber.
Background technology
In order to meet consumer to textile product variation, noveltyization, prevalenceization, it is advanced the needs of, fiber product is just
Develop towards the direction of high-quality, high added value, high-shrinkage fibre is one of which.Generally boiling water shrinkage 20%
The fiber of left and right is referred to as general high shrinkage, and the fiber that boiling water shrinkage is 35%~45% is called high-shrinkage fibre.Will
The blending such as high-shrinkage fibre and conventional chemical fiber, wool, cotton interweaves with the yarn of other species, and the product of exploitation has softness
Pendency, gloss is soft, double-colored flash of light, the new style of concavo-convex shrinkage, and laid a good foundation to develop this kind of fabric.
The method of production high-shrinkage polyster has two kinds of distinct methods of physical modification and chemical modification, physical modification be by
Conventional POY silks the high-shrinkage polyster that boiling water shrinkage significantly improves through cryogenic tensile, the low temperature technique productions such as shape,
High-shrinkage polyster can be directly produced by conventional section or with upstream raw material PTA etc.；Chemical modification is in the course of the polymerization process
Add the 3rd or the 4th monomer and Modified polyester chips are made, then produce high-shrinkage polyster again.Physical modification method cost
It is relatively low, and chemical modification method high shrinkage is relatively stable.
It is all fine not over terylene although being at present improved by above-mentioned physical method or chemical method
The structure of the fiber of dimension itself is improved.
Simultaneously current fire resistance fibre is all to carry out fire-retardant, the fire retardant meeting that such mode is added by adding fire retardant
Cause the partial properties of fiber to reduce.
The content of the invention
The purpose of this utility model is to solve the problems, such as the improved method of current polyester staple fiber high shrinkage, there is provided
A kind of fire-retardant high-shrinkage fiber.
In order to reach above-mentioned purpose of utility model, the utility model uses following technical scheme：
A kind of fire-retardant high-shrinkage fiber, the cross section structure of the fire-retardant high-shrinkage fiber include sandwich layer, sandwich layer
The week side of boss is provided with some spiral blade layers, is provided with flame-retardant layer between each blade layer, flame-retardant layer accounts for the 20-40% of whole cross section.
Preferably, the sandwich layer is hollow structure.
Preferably, the blade layer is set for non-centrosymmetry.
Preferably, the width of the blade layer is cumulative from the inside to the outside.
Preferably, the section of the fire-retardant high-shrinkage fiber is ellipse.
Preferably, the root of the blade layer is arranged at intervals.
Preferably, the number of the blade layer is 5-6.
Preferably, the outer ledge of flame-retardant layer is arc.
Compared with prior art, beneficial effect is the utility model：The utility model uses petal-like structure, will be fire-retardant
Layer is combined with each other with polyester layer in the form of interval so that polyester fiber possesses good flame retardant effect.Meanwhile by sandwich layer
Outer blade layer is arranged to helical structure, can so change the configuration of fiber so that and the crystallization of fiber everywhere is uneven,
Such setting can make fiber possess preferable shrinkage after treatment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is another structural representation of the present utility model.
In figure：1 sandwich layer, 2 blade layers, 3 flame-retardant layers.
Embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment 1：
A kind of fire-retardant high-shrinkage fiber, as shown in figure 1, in order to provide a kind of flame retardant effect preferable fire resistance fibre,
The cross section structure of the fire-retardant high-shrinkage fiber sets as follows：
First, its section includes sandwich layer 1, and sandwich layer 1 exists as skeleton, and it is spiral to be provided with several in the week side of boss of sandwich layer 1
Blade layer 2, specially 5-6, and be arranged at intervals between the root of blade layer 2；Then it is provided between each blade layer 2 fire-retardant
Layer 3, each flame-retardant layer 3 is arranged between blade layer 3 independently of each other, in order to prevent flame-retardant layer from departing from, specially by the width of blade layer 2
Degree is cumulative from the inside to the outside.It can so combine between flame-retardant layer is secured firmly to two blade layers 2 by spiral helicine structure, improve
Flame-retardant layer and sandwich layer 1 and the conjugation of blade layer 2.In order that flame-retardant layer 3 is reduced on the premise of flame retardant effect is reached to poly-
The performance impact of ester fiber, the area of flame-retardant layer 3 is arranged to account for the 20-40% of whole cross section.
In order to improve the highly shrinkable energy of the polyester fiber, the structure of blade layer 2 is improved, due to current height
Shrink all by being thermally treated resulting in, therefore by blade layer 2 be non-centrosymmetry setting, so further change fiber by
Uniformity after to heat treatment, so as to improve the shrinkage of fiber, and crimp property.
In addition, by the sandwich layer 1 to be arranged to hollow structure, low-fiber translucency can drop in the hollow structure, improve
Anti- transparent effect.
In order to produce positive influences to shrinkage, the section of fire-retardant high-shrinkage fiber is also arranged to ellipse.
Embodiment 2：
As shown in Fig. 2 being improved on the basis of embodiment 1, the avris of the blade layer 2 and flame-retardant layer 3 is arc
Shape, blade layer 2 and flame-retardant layer 3 make it that the outline of the fiber is petal.
