Abstract
An improved cationic dyeable copolyester draw textured feed yarn, the novelty of which lies in: the filaments are coaxial sheath-core filaments, the sheath layer of which consists essentially of a cationically dyeable copolyester, and the core of which consists essentially of a homopolymer; and under economically viable conditions, on commercial machines, stretch-textured such feed yarns to provide textured yarns with low yarn breakage and improved bulk.
Description
The present invention relates to improve cation dyeable copolyester draw textured feed yarn and improvement thereof.More particularly, relate to the novel feed yarns of coaxial core/sheath type bicomponent filaments, this improvement feed yarns can be stretched distortion at higher velocity pull-down, provide quite bulk textured filament, and broken wires is lower; Also relate to the textured filament of generation, and contain the fabric and the clothes of this textured filament.
People know that the synthesizing polyester multifilament used decades commercial, it at first be by W.H.Carothers at United States Patent (USP) 2,071, propose in 251, Whinfield and Dickson be at United States Patent (USP) 2,465 then, also it introduced in 319.That produced and are polyethylene terephthalate at the commercial most of polyester polymers that are used for long filament, be called 2G-T sometimes.This polymer still is often referred to as homopolymers, although well-known, except it contains ethylidene residue and the terephthalate residues from dimethyl terephthalate (DMT) or terephthalic acid (TPA) from ethylene glycol, also contains the residue from diethylene glycol (DEG).With regard to the purpose that is used to prepare textiles (clothes), the inherent viscosity of this commercial homopolymers is about 0.6 usually, also can become high to 0.65 even 0.67, also can be more lower slightly.Commercial homopolymers dyeing is very difficult.Such homopolymers majority is to use disperse dyeing under high-temperature pressurizing, this process not only expensive but also bothersome (with under the normal pressure some other commercial fibres are carried out dyeing course and compare, as when seething with excitement), therefore existing some of the recommendations are used for improving the stainability of Polyester Filament.
So Griffing and Remington be at United States Patent (USP) 3,018, the use cation dyeable copolyester has been proposed in 272, wherein, utilization can be carried out modification to the structure of polyethylene terephthalate with the sulfonate groups of cation dyes affinity.This cation dyeable copolyester mainly is made up of poly-(ethylene glycol terephthalate/5-sodium sulfonate group isophthalic acid ester), approximately contains 2%(mol in the polymer chain) 5-sodium sulfonate group M-phthalic acid ester group.This copolyesters is called 2G-T/SSI sometimes, and over 20 years, this copolyesters is at the commercial basic material that is used as Polyester Filament.Though, this cation dyeable copolyester than the homopolymers costliness many, it still is used for various application, particularly staple fibre and colour mixture compound silk on a large scale.In the colour mixture compound silk, the cation dyeable copolyester long filament mixes mutually with the homopolymers long filament.
A large amount of homopolymers has been used for making draw textured feed yarn.This thought at first be by Petrille at United States Patent (USP) 3,771,307 and Piazza, Reese at United States Patent (USP) 3,772, propose in 872.These draw textured feed yarns (DTFY) are the multifilament (long filament) of amorphous spun orientation basically, spinning is made under about 3000ypm or higher winding speed, its winding speed substantially with Petrille and Piazza, Reese set forth identical.These winding speeds are used for obtaining to make the required spun orientation of feed yarns stabilisation (pining for storing and add, so that stretcher strain).Yet feed yarns preferably is unbodied basically, promptly has quite low degree of crystallinity.This just low-crystallinity comes DTFY and the drawn polyester yarn difference that is used for fabric processing (as woven, knitting).The present invention relates to and be directly used in other DTFY of crystallization sex pilus phase region of fabric, promptly spun orientation but the feed yarns of low-crystallinity.Present most of commercial DTFY has about 10% crystallization and higher boil-off shrinkage.This shrinkage factor is about 40% usually.On the contrary, commercial drawn polyester yarn has the degree of crystallinity greater than 30% usually, and 15% or littler boil-off shrinkage.Can be by under different conditions, comprise that spinning under the condition very at a high speed obtains the spun orientation silk of crystallization, as Frankfort and Knox at United States Patent (USP) 4,134, in 882 and 4,195,051 disclosed like that.These silks can carry out stretcher strain.Yet according to the present invention relates to, this crystallization silk is not that we are desired, preferably uses low-crystallinity spun orientation silk, and this can be by at least 15%, preferably be at least 25% boil-off shrinkage embodies.
As above-mentioned, common homopolymers DTFY produces in a large number, and has been used for stretcher strain.Although the 2G-T/SSI copolymer is gratifying with respect to the Polyester Filament of other type, the client still complains: compare with common homopolymers DTFY, 2G-T/SSI DTFY has unacceptable high broken filament number (BFC) yet up to now.This fact really, as on Barmag FK6 machine, speed with 500-600m/min, under the condition of about 1.6 times of draw ratios, preparing 150/68(Denier per filament number by stretcher strain 250/68 DTFY) situation of 2G-T/SSI copolyesters textured filament is exactly an example.Above-mentioned deformation condition is commercial has used several years, and is used for regular homopolymers DTFY, has obtained acceptable BFC value, and its value is approximately 0.5/1b or littler (the silk head that detects the textured filament package counts to get).Although people have done many effort so far, still do not have to find to improve the practical approach of 2G-T/SSI copolyesters DTFY, so that aspect economical price, satisfy client's needs by changing manufacturing technique.
The DTFY that the purpose of this invention is to provide the cation dyeable copolyester that satisfies this respect needs.
Barmag(Schippers) in German DE OS 2335946, propose, use multicomponent filaments, make every meter long silk have 2000 circles at least, make crimp filament by heating false twisting simultaneously.In this process, what have a kind of component to have to be different from other component in the multicomponent filaments at least influences its length or length behavioural trait.Bicomponent structure can be common known materials make any.The example 2 has been set forth, and under the 3km/min condition, prepares coaxial core-skin type long filament by nylon 6 and polyester co-spun yarn; At draw ratio is 1: 1.25(1.25 is doubly) under, use single heater (need not second heater), under 220 ℃, stretcher strain core-skin type long filament.It all is the parallel type bicomponent filament of polyamide that other example has been set forth.Barmag did not disclose the concrete combination of 2G-T/SSI copolyesters in any bi-component combination.
Lee is at United States Patent (USP) 4,059, compound silk with colour mixture colouring power is disclosed in 949, two sets of filaments that this compound silk is made up of the polymer of two kinds of coloured differently performances constitute, wherein one group is a kind of long filament of polymer one pack system, another group is the long filament that is essentially coaxial skin-core structure, and its cortex is another kind of polymer, and its core is the polymer identical with single component filaments.This silk dyeing provides the colour mixture outward appearance, and is different with outward appearance based on phase that polymer composition gives of silk.Lee had not both related to DRFY and had not related to draw texturizing yet.The example 1 has been set forth, and by the method for spinning, quenching, stretching continued operation, by the preparation process that the 2G-T/SSI of the 14HRV of the 2G-T of the 22HRV of fusion and fusion produces the colour mixture silk of 34 threads, wherein 7 is the long filament of the 2G-T/SSI of one-component; 27 is the basic coaxial core/sheath type bicomponent filaments that is, its core is 2G-T/SSI, and its cortex is 2G-T.The colour mixture silk of these stretchings is not having false twist texturing under the situation about stretching then.Most of relevant claim relates to this combination, and this combination is goodish, and this point can be seen from the great majority of specification are described.Yet the claim 10 that is subordinated to claim 1 relates to such feature, and promptly the one-component long filament is made up of 2G-T, and the core-skin type long filament is made up of 2G-T core and 2G-T/SSI cortex.Go on the document the 4th hurdle 28, also relate to cortex and be the basic dyeing component and core is the reverse situation of disperse dye dyeable component.In this opposite situation, not only available DISPERSE DYES of 2G-T/SSI cortex but also available basic dyeing; The only available disperse dyeing of 2G-T core.Yet under better situation, core and cortex can both be with disperse dyeing and without basic dyeing (the 4th hurdles, 14-28 is capable).
According to the present invention, the cation dyeable copolyester draw textured feed yarn of improvement is provided, wherein cation dyeable copolyester is made up of poly-(ethylene glycol terephthalate/5-sodium sulfonate group isophthalic acid ester) basically, the content of 5-sodium sulfonate group M-phthalic acid ester group is 2%(mol in this polymer chain), above-mentioned feed yarns is the multifilament that is about the essentially no setting spun orientation of spinning preparation under 3000ypm or the bigger condition at winding speed.It improves feature: multifilament is coaxial core/sheath type bicomponent filaments, and its mediopellis is made up of cation dyeable copolyester basically, and core is made up of polyethylene terephthalate basically, and inherent viscosity is about 0.6.This bicomponent filament preferably is made up of the cortex and the core of weight such as being similar to substantially.The advantage of DTFY of the present invention particularly in, this long filament has less DENIER number, is approximately 5dpf or littler.
The present invention also provides the method for this feed yarns drawn one false twisting-distortion being made the cation dyeable polyester textured filament, the polyester textured filament of generation is provided, and contains 10%(weight at least) this polyester textured filament, fabric and the clothes of preferably forming by this polyester textured filament basically.
Accompanying drawing is the microphotograph of the cross section of bicomponent filament of the present invention.
The manufacturing of one pack system polyester DTFY was fully set forth in the prior art, and as in above-mentioned United States Patent (USP) 3,771,307 and 3,771,872, its disclosed content is incorporated herein by reference; These current techiques only need to improve slightly, promptly just can be applied by the spinning that coaxial bicomponent filament is provided, as use the disclosed spinnerets in Fig. 1 left side in the above-mentioned United States Patent (USP) 4,059,949, and the content of this patent disclosure also is incorporated herein as a reference.Should be noted that United States Patent (USP) 4.059,949 from having opened the preparation of the colour mixture silk that comprises coaxial bi-component drafted fibre (and one-component drafted fibre), but do not relate to the preparation of DTFY.The preparation of bicomponent filament that is used for polyester DTFY by Mirhej at United States Patent (USP) 4,157, open in 419.Should be noted that Mirhej discloses the preparation of eccentric bicomponent filament, its objective is character, in stretcher strain, make its fracture to produce helix-coil according to off-centre.And bicomponent filament of the present invention is coaxial, and its main purpose is to stop its fracture in the stretcher strain process of routine.The further details of gratifying coaxial bicomponent filament constructed in accordance and DTFY, promptly the distortion details about them will provide in the example below.Can finish with current techique by the textured filament manufacturing fabric and the clothes that generate.The advantage of improving (minimizing) BFC is considerable, compares with the long filament of one-component 2G-T/SSI copolymer, and its advantage is to have increased bulkiness.According to the present invention, the further advantage of DTFY is, compares with 2G-T/SSI, want considerably cheaper as the price of the homopolymers of novel bicomponent filament core, thereby the cost of material of bicomponent filament is more much lower than the price of 2G-T/SSI single component filaments.Because these spread effects economically had many use bicomponent filaments to be used for the suggestion of other various purposes in the past, but nobody proposes the present invention quite curiously.
The present invention will further set forth in the example below.Most various experimental measurement can be with reference to the United States Patent (USP) 4,156,671 of Knox.Yet about tensile property, we use 6 inches long, untwisted samples, measure under the extension speed of per minute 200%.The stress-strain curve that " natural draw ratio " (NDR) in the 5.4.1 chapter (174-177 page or leaf) by polyester fiber one book of being published in 1971 by John.Wiley and Sons Co., Ltd, Luderwig set forth is determined." natural tensile force " is the tensile stress values that is applied on the silk (NDF), and its value is in being lower than the zone of natural draw ratio, obtained by the linear portions of stress-strain curve.NDR described here and NDF are under 70 and 65% relative humidity condition, use 5 inches long samples, and it is definite to measure its load-deformation curve with the rate of extension of per minute elongation 400% on the Instron tension tester.The rate of crispaturaing (CCA
5) method in the available basically United States Patent (USP) 4,134,882 measures.The method of measuring LRV is disclosed in the United States Patent (USP) 4,444,710 of Most.
Example
Adopt 286 ℃ bulk temperature, the winding speed of 3315ypm, United States Patent (USP) 4,059, the 949 described cardinal principles of other conditions and Lee are identical, make 240/68 pair of component feed yarns.Its core is 0.61 for the 19.4LRV(inherent viscosity) at 2G-T, its coaxial cortex is the 98/2 2G-T/SSI copolyesters (inherent viscosity is 0.49) of 12.8LRV, the weight ratio of core and cortex is 50/50.This silk is handled with coml stretcher strain post processing and interweaving method.The silk that is generated has following characteristic; Intensity 1.3g/d; Elongation 117%; Modulus 24g/d; Natural draw ratio 1.4; Nature tensile force 150g; Shrinkage factor 45%; Density 1.347; Birefringence 0.02.The cross section of silk is illustrated in the microphotograph of accompanying drawing.
This silk on the Murata machine, stretcher strain under general condition.Compare with the contrast silk that only contains 2G-T/SSI copolyesters one-component for preparing with similar method, the fracture of wire much less and the crimpiness of bi-component feed yarns of the present invention are better.It can be seen from the table this can be.

Find that also use accurate basically deformation condition, the rate of crispaturaing that (0.5-1.0mg/ DENIER) surveyed under various loads all has corresponding improvement, this may have can increase the advantage that bulkiness can reduce fracture of wire again, and we are desired just for this.
Use current techique, as knitting or woven (if need), can this textured filament is processed into fabric, although the existence of homopolymer core is arranged, still available CATION and (or) DISPERSE DYES dyes charming look with it and translates.
Said just as top example, it is homopolymers/copolymer of 50/50 that the long filament of core-skin type of the present invention (DTFY) contains weight ratio, because density is roughly the same, thereby they occupy about equally area on cross section.The diameter of core (identical with the cortex internal diameter) is approximately 10.5 microns, and the external diameter of cortex (also being the external diameter of long filament) is approximately 15 microns.In other words, the thickness of cortex (each side) only is about 2 microns.The reducing of the skin thickness of feed yarns may make modified product more bulk, and fracture of wire still less, dyeing is more shallow.Increase colouring power if desired, can realize by the ratio that increase is used for the SSI of cortex copolyesters.Like this, emphasized hobby and the commercially available 2G-T/SSI copolyesters of people for many years although this specification is set forth, but still should understand: according to the present invention, for the copolymer cortex and homopolymer core and silk of bi-component silk, the accurate ratio of polymer, component and creating conditions of they can change, and still do not break away from base region of the present invention.For example the viscosity of homopolymers can change to about 0.67 by 0.6.If desired, generally also can use additive, as pigment or delustering agent, as titanium dioxide.
