For the crimp filament A that takes out from woven fabric or knitted fabric that treats as crimp filament, poor (DC-HC) between importantly wherein dry crimp percent DC (%) and the wetting crimp percent HC (%) is at least 10%.
This crimp filament A is preferably selected from water imbibition with from curling conjugate fibre differing from each other aspect the extensibility, this crimp filament A is made up of mylar component and polyamide component with form combination side by side, and has the curling of forming by their performance of potential curl characteristics.
As the mylar component that is ready to use in conjugate fibre, preferably have and bonding those of above-mentioned polyamide height, and for example, the preferred modified poly ester that uses, as polyethylene terephthalate, polytrimethylene terephthalate or polybutylene terephthalate (PBT), its can with the compound copolymerization of sulfate with alkali metal or alkaline-earth metal Huo Phosphonium, and it has one or more functional groups that can form ester.Wherein especially preferred is modification polyethylene terephthalate with above-mentioned compound copolymerization, because their versatility and polymer cost are low.The example of copolymerization component in the case comprises 5-sodium sulfo isophthalate and ester derivant thereof, and the 5-Phosphonium is for M-phthalic acid and ester derivant thereof, p-hydroxy benzenyl sulfonate sodium or the like.5-sodium sulfo isophthalate preferably wherein.The amount of copolymerization is preferably 2.0-4.5 mole % with respect to the acid constituents in described mylar.Bonded interface if the amount of described copolymerization less than 2 moles of %, can show good crimp property between polyamide component and mylar component may peel off.On the contrary, if the amount of copolymerization greater than 4.5 moles of %, can suppress the crystallization of mylar component in the stretching heat treatment process, therefore need be than higher stretching heat treatment temperature level usually, and potentially cause a large amount of yarn breakages.
On the other hand, the polyamide component is not particularly limited, as long as it has amido link on main chain, and can mention nylon as an example-4, nylon-6, nylon-66, nylon 46 and nylon 12.Wherein from especially preferred nylon-6 of the viewpoint of versatility, polymer cost and wrapping wire stability and nylon-66.
Mylar component and polyamide component also can contain known additive for example pigment, matting agent, anti-fouling agent, fluorescent whitening agent, fire retardant, stabilizing agent, antistatic additive, photostabilizer, ultra-violet absorber or the like.
Profile shape for the conjugate fibre side by side of described crimp filament A is not particularly limited, not and the mylar component in this profile and the joint line between the polyamide component can come down to or be straight line fully.The example of the shape of the cross section of described conjugate fibre is shown among Fig. 1-3.In Fig. 1, conjugate fibre 1 has the shape of cross section of annular, and is made up of mylar component 2 that combines and polyamide component 3, has the joint line that comes down to straight line.In Fig. 2, conjugate fibre 1 has oval-shaped shape of cross section, and is made up of mylar component 2 that combines and polyamide component 3, has the joint line that comes down to straight line.In Fig. 3, conjugate fibre 1 has the shape of cross section of annular, and form by mylar component 2 that combines and polyamide component 3, but described polyamide component 3 has the shape of cross section of sub-circular, and be arranged in the mylar component of the shape of cross section that also has sub-circular, the position is close like eccentric core-integumentary pattern structure.Yet a part of edge of mylar component 3 is the part edges that expose and form conjugate fibre.
The shape of cross section of conjugate fibre can not be annular or ellipse but polygon for example triangle or square, or star or or even hollow.Yet the shape of cross section of conjugate fibre is preferably annular and reduces crimp percent with convenient water when wetting effectively.
The weight ratio of two kinds of resin Compositions is not particularly limited in the conjugate fibre of crimp filament A, but the mylar component is preferably 30 with respect to the weight ratio of polyamide component: 70-70: 30, more preferably 40: 60-60: 40.
Quantity for the independent long filament of the independent long filament thickness of crimp filament A or the crimp filament A that contains in the crimp filament yarn has no particular limits, but the thickness of long filament is preferably 1-10dtex and 2-5dtex more preferably separately.Separately the quantity of long filament is preferably 10-200 and 20-100 more preferably in crimp filament A yarn.
The conjugate fibre side by side of the non-crimping of being made up of above-mentioned two kinds different resin Compositions has potential curl characteristics, and therefore shows curling when experiencing the heat treatment of for example high-temp dyeing processing.In this curling conjugate fibre, preferred described polyamide component is positioned at curling inside, and the mylar component is positioned at curling outside.When the curling conjugate fibre with this coiled structure is used water-wet, being positioned at the inner polyamide component of curling is expanded and expansion by water-soluble, and be positioned at curl outside mylar not by water-soluble expand and their length constant, this makes the crimp percent of conjugate fibre reduce, and apparent length increases.On the other hand when with the curling conjugate fibre of water-wet when dry, the polyamide component is shunk and mylar length does not change, and this makes the crimp percent of conjugate fibre increase and the apparent length of the conjugate fibre that curls shortens.
Described crimp filament A is preferably in not twist yarn that is not more than the 300T/m twist or false twist yarn, so that crimp percent and the elongation of minimizing when with water-wet.Especially preferred twist yarn not.Use has the tight twist yarn of heavy twist greater than 300T/m, when using water-wet, curls and reduces sometimes.
Equally, the yarn that contains crimp filament can pass through, and for example, alternately air-treatment and/or false twisting are handled, and this processing can cause the staggered of independent long filament in the yarn, and staggered quantity is 20-60/m.
