The synthon or the staple fiber has the advantages of high hollowness, good bulking property, good rebound resilience, good warmth retention property, and dry touch, and can continuously release negative oxygen-ion and clean the air, thereby realizing effects of infrared radiation warmth retention, bacteriostasis, and peculiar smell elimination. The synthon or the staple fiber is suitable for being utilized as fabric filling material, bunting, supatex fabric, carpet, fur-like fabric, filtering material, and the like.
Description
The utility model relates to a kind of special-shaped synthetic fiber, specifically, the utility model relates to the negative ion type synthetic fiber that a kind of its cross section is the porous hollow form, can discharges negative oxygen ion lastingly, more particularly, the utility model relates to the negative ion type three-dimensional crimp polyester staple that a kind of its cross section is the seven apertures in the human head shape.
Single hole, or porous, and particularly the three-dimensional crimp staple fibre of porous has that degree of hollowness height, fluffy excellent performance, rebound performance are good, thermal property reaches advantages such as feel is smooth by force.Thereby the three-dimensional of porous and staple fibre thereof are specially adapted to as cloth art packing material, bunting, supatex fabric, carpet, wool-like fabric and filtering material etc.For this reason, up to now, existing multiple single hole or porous three-dimensional staple fibre come out.
For example, application number is the fiber spinneret that the Chinese patent of " the high degree of hollowness 3 D stereo crimped fibre spinnerets " of " 92244356 " discloses a kind of single hole hollow, uses this spinnerets to spin and obtains a kind of single hole doughnut.Application number discloses a kind of spinning equipment and spinning process thereof of single hole hollow polymer fiber for the Chinese patent of " spinning equipment of hollow polymer fiber and the method " of " 9619836 ", according to described spinning equipment and spinning process thereof, can spin the single hole doughnut that obtains a kind of hole wall densification.In addition, application number discloses a kind of spinning process of single hole hollow activated carbon fiber for the Chinese patent of " preparation method of hollow activated carbon fiber " of " 95119030 ", thus, spinning obtains single hole doughnut carbon containing, that can be used for fields such as catalysis, medicine, electronics liquid phase adsorption.But said method or spinnerets can only spin and obtain the single hole doughnut.
Again, application number has then been introduced a kind of the spinning for the Chinese patent of " Six-hole spinnerette " of " 96220288 " and has been obtained the polyester staple fiber that its circular cross-section is essentially six holes.
Self-evident, many more being difficult to more of the hollow porous number of fiber makes.Yet on the other hand, the hollow hole count of fiber is not The more the better yet, and the hollow hole count of fiber has inseparable getting in touch with the fiber number of fiber, three-dimensional crimp degree and product requirement.Simultaneously, also must consider the processing characteristics and the price/performance ratio thereof of product.
In addition, the fabric of three-dimensional crimp tend to produce peculiar smell, and negative oxygen ion can improve IAQ after for a long time as things such as cushions, the various peculiar smell after the elimination fabric is used for a long time.Yet though conventional art also has the technology report that fabric is used for negative ion generating device, Shang Weiyou crosses and will make the example of the negative ion type fiber that can produce negative oxygen ion as the fiber itself of fabric web material.
The purpose of this utility model is to provide the synthetic fiber of a kind of porous hollow form, negative ion type three-dimensional crimp, described fiber has best joint between the hollow hole count of fiber and fibre number, three-dimensional crimp degree and product requirement, and has the processing characteristics and the price/performance ratio thereof of excellent product.
The purpose of this utility model is to provide the synthetic fiber or the staple fibre of a kind of seven apertures in the human head hollow form, negative ion type three-dimensional crimp again, described fiber is to reach the negative ion type fiber that nano level ultrafine tourmaline powder makes with powder fineness, described negative ion type fiber can produce anion lastingly, improve IAQ, the various peculiar smell after antibacterial, elimination fabric is used for a long time.
The synthetic fiber of seven apertures in the human head negative ion type of the present utility model three-dimensional crimp are characterised in that the cross section of described synthetic fiber is seven emptying apertures.
