Description

Flexible fluff type staple fiber

Technical field

The present invention relates to a kind of fiber, especially a kind of flexible fluff type staple fiber.

Background technique

Staple fiber is the fibre bundle being processed by various chemical fibre textiles and cuts into and be equivalent to various natural fibers The fiber product of length is widely used in woven fabric, rope making, fiber processed, knitting, embroidery and when filler etc..For filler For, the most important function of staple fiber is fluffy and has elasticity, enables to be filled object in guarantee whole object weight In the case where, so that whole object is filled completely, when in use, after object is crushed, original shape can be replied, generally The staple fiber intensity of the prior art is low, and poor flexibility, lofting effect is unobvious, is easily broken off, and more difficult to restore after deformation, anxious It needs to improve.

Summary of the invention

It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of short fibre of flexible fluff type is provided Dimension, intensity is high, and elasticity is good, and lofting effect is good and not easy to break.

In order to achieve the above objectives, the technical scheme is that flexible fluff type staple fiber, including it is located at center First of position, first section are pentalpha, and first outer rim forms five uniformly distributed protrusions, two neighboring Second and two third silks are equipped between protrusion, the section of described second and third silk is triangle, and two third silks are right Claim be located at second two sides, the protrusion, third silk, second, third silk and protrusion successively fitting setting, described second with The point of interface of one endpoint of third silk and corresponding two neighboring protrusion is overlapped, described second and third silk other two Endpoint is inscribed on the 4th inner wall, and described 4th is coated on first periphery and along first length direction interval It is uniformly arranged, described first is inscribed on the 4th inner wall, is equipped with and runs through on described first, second and third silk The through-hole of its length direction.

Described first is made of terylene.

Described second is made of spandex.

The third silk is made of polyamide fibre.

Described 4th is made of acrylic fibers.

The beneficial effects of the present invention are: first in center uses, terylene is made and pentalpha is in section, Each protrusion symmetrically, improves the fluffy degree of staple fiber, while elasticity is good, and second is filled in two phases with third silk Between adjacent protrusion, first intensity is increased, so that first is not easy to be pulled off, with the 4th by first, second It encloses the intensity for further enhancing staple fiber inside it simultaneously with third silk, increases pull resistance.

Detailed description of the invention

Fig. 1 is the structural diagram of the present invention；

Fig. 2 be Fig. 1 in A to partial schematic diagram.

In figure: first 1, protrusion 2, second 3, third silk 4, through-hole 5, the 4th thread 6.

Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

As shown in Figure 1 and Figure 2, flexible fluff type staple fiber, including being located at first 1 of centre, described the One 1 section is pentalpha, and first 1 outer rim forms five uniformly distributed protrusions 2, each raised 2 size and shape Identical, described first 1 is made of terylene, and the scientific name of terylene is polyethylene terephthalate, abbreviation polyester fiber, its bullet Property it is all stronger than any fiber, intensity and wearability are preferable, and not only fastness than other fibers is higher by 3~4 times to the fabric weaved by it, And be unlikely to deform, have a laudatory title of " non-ironing ", the heat resistance of terylene be also it is stronger, there is preferable chemical stability, just Under normal temperature, it will not all have an effect with weak acid, weak base, oxidant, first in center thread 1 can enhance of the invention The elasticity and recovery capability of staple fiber, can be restored to original state after use, to ensure that the use longevity of the invention Life.

Second 3 and two third silks 4, the section of described second 3 and third silk 4 are equipped between two neighboring raised 2 For triangle, second 3 of the odd-shaped cross section of the triangle and third silk 4 have the characteristics that coherent is good, so what is formed is short Fiber is very secured, which can be improved the tensile strength of staple fiber, and two third silks 4 are symmetrically positioned in second 3 two sides, institute State the successively fitting setting of protrusion 2, third silk 4, second 3, third silk 4 and protrusion 2, one of described second 3 and third silk 4 Endpoint is overlapped with corresponding two neighboring raised 2 point of interface, and described second 3 is made of spandex, and the third silk 4 is by polyamide fibre It being made, spandex is a kind of chemical fibre with special elastic property, and elastomeric polyurethane fiber is excellent, and fibre density is also thinner, and More resistant to chemical degradation, the resistance to acid and alkali of spandex, sweat proof, sea water resistance, dry cleaning resistance, wearability are preferable, when user makes Used time has sweat to drip in staple fiber, and second 3 thereon has the characteristics that corrosion resistance is strong, can extend using the time, and Elastic strength is high, is easy to the stretching of staple fiber, and be not easy to break.Polyamide fibre is called Fypro, has intensity height, wearability Good feature, second 3 and third silk 4 are filled between two adjacent protrusions 2, increase first 1 intensity, so that the It is not easy to be pulled off for one 1, while increasing elasticity of the invention.

Other two endpoint of described second 3 and third silk 4 is inscribed on the 4th 6 inner wall, the 4th 6 packet It overlays on first 1 periphery and is uniformly arranged along first 1 length direction interval, described first 1 is inscribed in the 4th 6 On inner wall, described 4th 6 is made of acrylic fibers, and the white in appearance of acrylic fibers, curling, puffy are soft, can increase short fibre Whole fluffy performance is tieed up, and structural strength is high, is not easy to be pulled off, with the 4th 6 by first 1, second 3 and third silk 4 The intensity for further enhancing staple fiber inside it is enclosed simultaneously, increases pull resistance.

The through-hole 5 through its length direction is equipped on described first 1, second 3 and third silk 4, when the staple fiber When in use, staple fiber is compressed, each through-hole 5 is closed, in air outflow, may make staple fiber that there is ventilative function Can, it ensure that the gas permeability and air circulation of filler, and after air enters through-hole 5, filler can be driven to be returned to original The shape come.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art, It should be covered by the protection scope of the present invention.
