Description
The present invention relates to a kind of fiber that is applicable to bedding and inside stuffing matter, this fiber is sneaked in the padding, is used for mattress, bedcover, pillow; Load the doll, knitting wool, the processing knitting wool of yarn and woollen blanket, carpet etc.Make these article have lasting fragrance.In addition, the invention still further relates to a kind of fiber that is applicable to bedding and interior articles for use aspect, in this fiber, natural essence oil be used as spices by separating the component that obtains in the natural essence oil, make above-mentioned article have lasting " forest result of treatment ".
In order to make fiber have aromatic odor, the method that has now adopted is: spices is absorbed or sticks on the final fiber product by post processing.Yet the shortcoming of this method is that the fragrance that adds is water-washed away easily, and the speed of spices volatilization is fast and fragrance that distribute is not lasting.If the natural essence that will gather from wild-type tree is oily or be used as spices from the isolated component of natural essence oil, because all these natural essence oil components nearly all are monoterpene and di-terpene compound, their boiling point is 150～190 ℃, and volatilization rapidly in air, at this moment above-mentioned shortcoming is especially obvious.
In order to eliminate above-mentioned fragrance from final fiber product this weak point that rapidly disappears, Japanese unexamined patent discloses the 48-93714 suggestion spices is dispersed on a kind of heart yearn component of core-skin type synthetic fiber.Yet this fiber has fragrance and renders a service low shortcoming, and is dense in order to cause fragrance simultaneously because spices can only evaporate into the extraneous air from the narrow and small fibre end surface of area, and the fiber number of synthetic fiber is very big, will reduce the pliability of fiber like this.
Main purpose of the present invention provides a kind of fragrant fiber that does not have the defective of above-mentioned conventional process techniques generation and have height washability and lasting fragrance.
The invention provides a kind of fragrant core-skin composite fiber, its cross section is made up of a cortex and a core that comprises hollow space, and a kind of boiling point under normal pressure is higher than 150 ℃ spices with 0.1～10.0%(weight) quantity be added into and be dispersed in the thermoplastic polymer that constitutes core.
Now the present invention is described in detail.
Owing to following reason, fiber of the present invention has good washability, lasting fragrance.In the present invention, spices is added into and is dispersed in thermoplastic polymer inside, and this polymer has constituted a core that hollow space is arranged on the cross section of core-skin composite fiber.Therefore, the volatile components of spices can only vertically spread in air along fiber by the hollow space of fiber cross section, and therefore, its washability is high especially.In addition, because hollow space always is filled with volatile perfume composition, so fragrance emanation is controlled lasting fragrance.
What Fig. 1 represented is the example of core-skin composite fiber cross section of the present invention, and this fiber has a hollow space in its cross-section center.It should be noted that the cross section of adopting among the present invention is not limited only to scope shown in Figure 1.
Because the characteristic of this fiber, the bulkiness when especially considering this fiber and be added in the steady volatilization of the spices in the polymer that constitutes core as filler, the cross section of fiber is preferably the real garden shape shown in Fig. 1-(A).
Among the present invention, the area of hollow space ratio on the fibre section, promptly hollow rate must be not less than 5%, if this hollow rate is lower than 5%, fragrance emanation just will be limited on the low water-mark, and insufficient fragrance.Hollow rate is high more good more, but with regard to core-skin composite fiber, it is very difficult making hollow rate surpass 50%.
If select wet, dried or fusion extensional polymer for use, the kind of the polymer of the core of formation hollow core-skin composite fiber is particular importance not.Yet from the viewpoint of production easiness, but the thermoplastic polymer of melt-spun is more desirable.Nearly all spices, especially natural essence oil composition all is that boiling point is 150-190 ℃ monoterpene and a double terpene compound, their poor heat resistance, be heated easily volatilization and decomposition.Therefore, use the low especially thermoplastic polymer of fusing point (softening point), spices is added and be dispersed in this thermoplastic polymer, and carry out the composite melt-spun at low temperatures and just seem desirable especially.The thermoplastic polymer of this formation core is a kind of unhydrolyzed polymer, this also be desirable a bit, this is because dry spices and when keeping dry spices added and when being distributed in the polymer, need finish the industrial operation of many complexity, and consider that from economic point of view these complex operations are worthless.
Alathon and ethylene copolymer (below be commonly referred to as " polyethylene polymer ") are the better polymerization thing.
Low density polyethylene (LDPE), intermediate density polyethylene and high density polyethylene (HDPE) all can be used as ethylene single-polymer.Certainly, also can use so-called straight linear polyethylene (to contain a spot of C in many cases
4Or C
6Comonomer composite), as ethylene copolymer, can use a kind of ethylene/vinyl acetate copolymer, therein ethylene and vinyl acetate are with 95/5～70/30 ratio copolymerization, also can use a kind of ethylene/ethyl acrylate copolymer, therein ethylene and ethyl acrylate are with 95/5～70/30 ratio copolymerization.
A kind of thermoplastic polymer is arranged in core, the polymer of forming the cortex of hollow core-skin fibre is good with thermoplastic polymer also, the thermoplastic polymer that is fit to as selecting in the polymer of making synthetic fiber, as polyalkenes, polyamide, reaches polyesters by common.On the performance of fiber, particularly consider the ability of bulkiness, activity and antifatigue sclerosis when fiber is used for padding.It is feasible using polyester, in this example, in order fully to give the fiber with excellent performance, preferably uses polyethylene to the benzene diester polymer, wherein has the 95%(mole at least) recycle monomer be that ethene is to benzene diester monomer.
Hollow core-skin fibre of the present invention can be according to the method preparation of the following example, with reference to Fig. 1-(A) this fiber is illustrated, two kinds of polymer constitute core for polymer 1() and polymer 2(formation cortex), be spun into the configuration of core-skin shape via the composite spinning spinning appts shown in the 2nd figure, according to general step, this fiber that is spun into is through chilled air cools, on fiber, apply a kind of finish, in then this fiber being introduced one jar, the core-skin of the spinneret orifice of the spinnerets among the embodiment and two kinds of polymer is disposed among Fig. 3 and illustrates, the spinneret orifice shape of this spinnerets is very important, and for the cross section hollow space that makes fiber is real garden shape, should give Fig. 4-(A) and 4-(B) shown in a kind of special shape in two ends, arc crack, shown in Figure 5 when having traditional spinnerets of general spinneret orifice shape when using, the shape of the fiber cross section of ejection can't obtain good result as shown in Figure 6.
Melt viscosity between formation core copolymer and the formation cortex polymer when melt-extruded is poor, is important factor for obtaining hollow core-skin fibre of the present invention.If differentiated different polymer are aggregated and weave on the degree of polymerization, and it is satisfactory to determine that the best degree of polymerization just is enough to by experience.When this polyethylene polymer is positioned in core, and polyethylene is when being placed in cortex to the benzene diester polymer, and the melt flow index of polyethylene polymer (M.I.) should be 0.5～25(and determines according to American Standard of Testing Materials ASTM D-1238; Unit: Grams Per Minute), and polyethylene should be 1.55 to 1.70(to the relative viscosity of benzene diester and determines at 25 ℃ in this tar of m-alcohol) be absolutely necessary.If employed polymer can not satisfy this condition, then hollow space can't form, even or form hollow space, its hollow rate is also very low, and hollow core-skin fibre of the present invention also can't obtain.In brief, selected two kinds of polymer satisfy following condition: when melt was extruded, the cortex polymer melt viscosity can be slightly higher than core copolymer, and this is very important.If it is suitable many that the melt viscosity of cortex polymer exceeds than the melt viscosity of core copolymer, this fiber can become as 7-(A) cross section shown in the figure, and if the melt viscosity of cortex polymer is low than core copolymer, then this fiber can have as 7-(B) cross section shown in the figure.
In the present invention, constituting core copolymer must be in 20/80 to 50/50 scope with the volume ratio that constitutes cortex polymer, if core copolymer/cortex polymer surpasses 50/50, then will be difficult to prepare certain skin-core structure, and the part of the fiber cross section shown in the 8th figure can increase; If the volume ratio of core polymer/cortex polymer is lower than 20/80, the amount that then adds the spices of core polymer can reduce, and its fragrance effect becomes insufficient; The spices that adds special volume in core copolymer can cause melt-spun stability to reduce, and can make single wire fracture because of foaming.
The spices that adds the formation core copolymer in the hollow core-skin fibre of the present invention is described it now.
Any artificial synthetic perfume and natural refinement spices can use in the present invention.Certainly, the mixture of multiple spices also can use.In the present invention, the boiling point of spices must be higher than 150 ℃ under the normal pressure.If the boiling point of the spices that uses is lower than 150 ℃.Then in cortex composite fibre of the present invention, the number that can be used to form the thermoplastic polymer of cortex can be subjected to strict restriction, and more desirable polymer such as polypropylene, polyamide-based and polyesters is neither can use.
In the present invention, adding and be scattered in the amount of the spices in the thermoplastic polymer that constitutes core, should be 0.1 to 10.0% by weight, is good with 0.5 to 2.0%.
If the amount of spices is lower than 0.1%(weight), then fragrance effect is weakened, and if the amount of spices greater than 10.0%(weight), then stability of spinning process reduces, and yarn breakage can often take place.
Spices kind used herein is not a particular importance, and for example, when fiber of the present invention was mixed for the padding of mattress, coverlet or pillow, using a kind of was feasible by the collected essential oil of coniferous tree; Because of can reaching with forest therapy, it similarly expects effectiveness.In addition, when fiber of the present invention was mixed in conduct filling doll's padding, employed spices had the smell of fruit, can recommend to use as strawberry or this spices of spinach sieve, and certainly, the spices with the fragrance of a flower or cedra fruits smell also can use.
