Description
The present invention relates to the yarn silk and the production technology thereof that are formed by the two component long filaments of core-skin type, the core silk and the skin silk of the two component long filaments of this core-skin type all are by being crushed to.
Two component long filaments of core-skin type and production technology thereof are widely known.For example, in document EP-A-O 011954, just point out:, must adopt special spinning equipment for avoiding when peel filament content is very low, occurring producing the phenomenon of one-component long filament.Although by adopting above-mentioned spinning equipment, can avoid producing the one-component long filament, but the yarn silk of making by the two component long filaments of core-skin type, still there is very big fluctuation inevitably in peel filament content in the long filament, even comprise the part that does not have some peel filament contents so that in the finished product gauze in the two component long filaments of core-skin type peel filament content fluctuate significantly.
Experimental results show that: with the spinning machine described in document EP-A-O 011954, import with 85: 15 volume ratio as described core silk of example and skin wire material, but in the yarn silk, the two component long filaments of the core-skin type of peel filament content about 15% (even the peel filament content fluctuation is thought of as ± 10%) be no more than 15%, general even less.The peel filament content of the two component long filaments of other core-skin type has higher (percent by volume reaches 30%) or lower (percent by volume is below 5%) in the yarn silk.
Under a certain control method, also can not in the yarn silk, obtain one or more one-component long filament with above-mentioned technology.The generation of one-component long filament by sheer chance can not guarantee in yarn silk cross section it is an one-component long filament and also be still an one-component long filament in yarn filament length degree direction.Opposite is, from the length direction of yarn silk, an one-component long filament can become the two component long filaments of a core-skin type, and vice versa.
The great fluctuation process of peel filament content makes the every threads in the yarn silk have different performances, that is to say that the performance difference of the long filament in the yarn silk is very big, and this is unfavorable.
Basically say, the yarn silk of being made up of the two component long filaments of core-skin type should have the ideal performance (intensity, contraction, elongation, birefringence etc.) of core-wire material material, and the skin silk then improves other performances (with adhesion, stainability, use fastness, anti-chemical and the anti-mechanicalness etc. of other materials) of yarn silk.In existing processes, for the fluctuation that keeps peel filament content in limited range, and holding core wire material performance is roughly even, is necessary for 20% or more more at the average external volume content of the two whole cross sections of component long filament of core-skin type epithelium silk.
The purpose of this invention is to provide novel, the better yarn silk of forming by the two component long filaments of core-skin type (it may comprise the one-component long filament) of performance, but the core silk and the skin silk of the two component long filaments of core-skin type are to be made through extruding by spinning polymer, and at least almost all the two component long filaments of core-skin type all have complete skin silk.This kind yarn silk guarantees to utilize preferably the characteristic of core-skin two-component materials, and the characteristic that can not lose the skin wire material.
Another object of the present invention provides a kind of technology that produces this kind yarn silk, and it guarantees that the yarn silk has the uniformity preferably, can and give the ratio that the state of establishing is divided into order component long filament and the two component long filaments of core-skin type in control simultaneously.The long-pending content of skin filament in the two component long filaments of core-skin type even also be comparatively uniform being lower than at 20% o'clock.
When the two component long filaments of every core-skin type have its corresponding two component long filament cumulative volumes (when the percentage P% that the two component long filaments of the core-skin type of the peel filament content of % of S ± 0.1S) account for the two component long filaments of the whole core-skin types of yarn silk met following condition simultaneously, this purpose can reach:
P≤100
S≥0.5
P≥30+（0.1S）
8
S ± 0.1S item represents that P depends on that having the long-pending content of skin filament in the two component long filaments of whole core-skin types is the two component long filament amounts of the core-skin type of the S% of the two component long filament cumulative volumes of its corresponding core-skin type.Peel filament content is determined on the basis of ± 10% scope.Because above-mentioned condition must meet simultaneously, therefore have only when P is not more than 100% and could set the S value.
Particularly according to yarn silk of the present invention, wherein
P≥40+7（0.1S）
8
As be preferably
P≥50+100（0.1S）
8
Excellent performance is then arranged.
According to predetermined purposes, the yarn silk may be selected to be have at least 60% two component long filaments of core-skin type have (the long-pending content of the skin filament of % of S ± 0.1S), the volume % of S is herein:
S≤9%
Perhaps select for use have at least the two component long filaments of 70% core-skin type have (peel filament content of % of S ± 0.1S), the volume % of S is herein:
1%≤S≤7%
Perhaps select for use and have at least the two component long filaments of 75% core-skin type that the (peel filament content of % of S ± 0.1S) is arranged.The volume % of S is herein: 3%≤S≤6%.
Surprisingly some properties of these yarn silks improve significantly, for example, yarn silk intensity of the present invention (CN/dtex) is apparently higher than the existing yarn silk intensity made from two component long filaments of core-skin type and the one-component long filament only made with core silk polymer.
According to the present invention, the long filament in the yarn silk can have in fact any known cross sectional shape.For example, the long filament that is used for tyre cord is had circular cross-section,, can preferably adopt the trifoil cross-section long filament if emphasize visual effect, for example just very desirable for carpet silk.
The property of yarn silk, for example adhesion is worked as long filament, two component long filaments of core-skin type particularly, when having the trifoil cross-section, this characteristic is just more outstanding.

Yarn silk according to the present invention has a lot of use.
Making the sewing thread that the core silk makes with polymer (PET, PA66, PA6) commonly used can coat with heat-resistant polymer, and this just goes for very high sewing velocity.With rope bundle or net that the yarn silk is made, Pi Si can improve its chemically-resistant, UV resistant and heat resistance.
When the yarn silk was used for strengthening elastomer, as tyre cord, it was to be used for fortified tyre, transmission belt or conveyer belt, and the Pi Sineng of the two component long filaments of core-skin type promotes the adhesion between core silk and the elastomer.Equally, for fibre reinforced plastics, the method strengthens the adhesion between yarn and the plastics.
During as the carpet yarn silk, the stainability that the Pi Sike of the two component long filaments of core-skin type promotes long filament, even when the core silk contained the high conduction material for strengthening antistatic property, its color was very gloomy often, also is difficult to dye other colors.Because the core silk is different with the shrinkage of skin wire material, uses this yarn silk to be made into carpet, after Overheating Treatment, the yarn silk of carpet that is made into or textiles will produce significantly and curl so.The heterogeneous yarn silk has improved the scattering property of light.The correct skin wire material of the two component long filaments of core-skin type of selecting has improved carpet and the combustibility of textiles and the contamination property of being made by the two component long filaments of these core-skin types widely, and is same, reduced mouldy and rotten.
A kind of Pi Sineng of hydrophobic material makes the two component long filament protection against the tide of core-skin type effectively.This makes textile limit interested in especially yarn silk of the present invention, also can go spinning as the mixture of polymers of the component of skin silk with pigment, produces solution dyed long filament.
If yarn silk of the present invention is used for supatex fabric, selective polymer can be promoted chemical resistance rightly, for example is used to filter the supatex fabric of dirt.Equally also can obtain ion-exchange performance, perhaps influence flammable degree.
Purpose of the present invention also reaches in the technology of producing the yarn silk by the present invention.(EP-A-O 011954) under normal conditions, core silk component is imported through first spinning plate to the second spinning plate with many independent silk streams, and between first and second piece spinning plate, the skin silk component that the independent silk stream of every core silk component is all imported just there coats, two kinds of components fuse and carry out spinning, stretch and reel, it is characterized in that: around the independent silk stream of core silk component, skin silk component affords flow resistance at least.
According to technology of the present invention, can realize one-step technology (not reeling in the middle of not having) or multistep processes technology (reeling in the middle of having).
A suitable Fluistor is a special woven wire, one hole is all arranged silk stream place separately at each.In addition, captured whole spaces between first and second spinning plate as woven wire, this is very favourable.Also can adopt other Fluistors, for example porous plate.Adopt woven wire even under the big relatively spinning plate situation of application, two distances between the spinning plate are consistent, because woven wire also plays a part division board.
Under the state that control is simply arranged, also may make each threads in the two component long filaments of the core-skin type of producing have different peel filament contents.For this purpose, can select different resistances to the Pi Siliu of each root core silk stream.If resistance is selected very greatly, make the skin wire material can not be coated on the corresponding core silk stream, consequently produce simple one-component long filament.
The X sieve mesh silk screen of the particularly commercial general R.V.S trade mark of suitable woven wire, wherein X is from 30 to 500, and R.V.S is a kind of stainless steel trade mark, and the X sieve mesh represents that woven wire every inch on two directions has the X one metal wire.Knit wire diameter into the net and be 0.5 to 0.025mm.
Flow resistance can be determined that permeability K is determined by following formula by the permeability of Fluistor
K＝- (ηV)/(δP/δX)
The viscosity of η fluid (Pa.S) in the formula
The V fluid is by the speed (m/sec) of Fluistor
δ P/ δ X is at the barometric gradient (N/m of flow direction
