Description

The present invention relates to an extensible synthetic polymer fiber = sexual elastic = core shaft core and a plurality of thermoplastically-containing, non-::; radially outer wings. The wing polymer or core is gathered in another polymer unearthed from Taiji y Λ, and the improvement of the wing-to-core attachment is also related to the production method of such fibers, and is used to form fibers. The present invention pertains to articles formed from such fibers, including articles, clothing, and the like. ^ 4 It is desirable to impart stretchability to many products formed from synthetic fibers, including various garments such as sportswear and knitwear. As disclosed in the background paragraph of the issued national patent No. 4,861,660, it is known that various kinds of extension properties are given to synthetic long ke "wanfa. In one of these methods, the fibers are shrunk in two or three dimensions. In another such method, stretchable filaments are made from an elastic polymer, for example, rubber or rubber, or a synthetic elastomer such as a polyurethane elastomer. The disadvantage of this type of stretchable filament is that the rubber or polyurethane elastic filament itself exhibits very poor wear and knitting processes and poor foot dyeing properties. Therefore, the disadvantages of the rubber of polyurethane elastomer filaments can be avoided by covering the rubber or elastic filament with another type of filament having satisfactory workability and dyeing properties. However, this type of covered elastic filament has related disadvantages. Ishii attempts to overcome this disadvantage by imparting asymmetry to the filaments formed by the two polymers. However, these fibers usually have two polymers, which are often susceptible to each other during processing. O: \ 74 \ 74152-911018.DOa 4 -4- 580527 A7 B7 V. Description of the invention (2) The serious defect of this separation. The resulting split fibers have low fracture toughness and produce fabrics with lower than expected sheerness and thermal conductivity. See also US Patent No. 3,017,686 issued to Breen et al., Which discloses fibers formed from two different non-elastic polymers and having these disadvantages. In fact, in US Patent No. 3,418,200 issued to Tanner It is known that protruding a core polymer into a wing polymer under certain conditions will actually make it easier to separate the wing portion from the protruding portion by a polymer different from the core and the protruding portion of the wing. In contrast, it may sometimes be desirable to improve the adhesion of two different polymers in a filament, as disclosed in US Patent No. 3,458,390, where a type of mechanical lock is used to bond two high modulus, low elastic polymers Together. However, such polymers, as well as the polymers disclosed in Breen and Tanner, do not have suitable stretching and restoring properties for the currently desired high stretch garments due to their low elasticity. The spinnerets disclosed in U.S. Patent No. 3,418,200 and U.S. Patent No. 5,344,297 can be used to spin fibers containing two polymers. However, when multiple polymer streams are incorporated into the feed channel substantially before the spinneret, polymer spin-off of these patented spinnerets will occur. These issues are described in Journal of Polymer Science [Physics Edition] Vol. 13 (5), p. 863, 1975, and more recently on other trilobal fibers with a tip designed to split from the core The latest type of spinning is more clearly shown in the International Fiber Journal (1998), Vol. 13 (5), p. 48. Therefore, there is still a need to have excellent stretch and recovery, and to process and make O: \ 74 \ 74152-9HOl8.DOa 4-5 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm). A fiber that retains its dynamics in the process and a convenient method for such fibers and objects derived from it. There is also a need-a spinneret for spinning, which eliminates the problem of polymer movement when a plurality of polymer streams are substantially combined with rain in the orifice of the plate in the feed channel. The invention is now found that if one of the two polymers penetrates the other polymer, that is, at least a part of one or more wings of the wing polymer protrudes into the core polymer, or at least one point of the core The polymer protruding into the wing polymer can substantially reduce or eliminate the splitting in the stretchable bi-polymer fiber (: layer shell) due to expectations (especially according to Professor T_er (before)) in the stress. Below θ, the elastic polymer will easily deform and pull out its interpenetrating connection with the non-elastic polymer, so this behavior is unexpected. Based on these findings, the present invention provides a stretchable synthesis Polymer fiber comprising a core comprising a thermoplastic elastic polymer and a plurality of wings attached to the core comprising a plastic, non-elastic polymer, wherein at least one of the wing polymer or the core polymer protrudes to another polymer In a specific embodiment, the shaft core includes an outer radius R1 and an inner radius h, & Ri / R2 is greater than about 100%. In another embodiment, the present invention provides an extensible synthetic polymer fiber including: With The core of the first polymer and a plurality of wings attached to the core including the second polymer, wherein the fiber has a delamination ratio of less than about i and at least about 20% post-sizing stretch (after-b. ii-〇ff stretch). In addition, with the spinneret package of the present invention, the multi-component polymer flow can be metered directly to the special -6- O: \ at the backside entrance of the fiber-forming orifice in the spinneret. 74 \ 74I52-911018.DOO 4 This paper size applies to China National Standard (CNS) A4 (210X 297 mm) 580527 A7 B7 V.

Therefore, according to the present invention, a spinneret package for melt-extruding a plurality of synthetic polymers to manufacture fibers is provided, which includes: A metering plate including a first set of holes that can accept a first polymer melt and a second set of holes that can accept a second polymer melt; a spinneret aligned and in contact with the metering plate, the spinneret having a through Capillary pores and those having a diameter less than about 60% of the pore length of the spinneret Pit length; and a spinneret support plate aligned with and in contact with the spinneret and having a larger capillary hole; wherein the plate is aligned so that a plurality of polymers supplied to the metering plate pass through the spinneret and the spinneret.

In the case of a plurality of wing feet, the polymer in some wings penetrates the core polymer, while the polymer in the other wings is penetrated by the core polymer, and Ri & R2 only corresponds to each wing.

580527 A7 B7 V. Description of the Invention (10) Textile Research Journal, June 1967, 449 pages. To achieve maximum cross-section radial symmetry, the core may have a substantially circular or regular polygonal cross-section, as seen in Figs. The so-called "substantially circular" refers to each other at the center of the cross section of the fiber. The ratio of the lengths of the intersecting two axes is not greater than about 1.2: 1. In contrast to the core of U.S. Patent No. 4,861,66 ', the use of a substantially circular or regular polygonal core protects the elastomer from contact with rollers, guides, etc., as described later with reference to the number of wings. The plurality of wings can be arranged around the core in any desired manner, for example, as discontinuously arranged as depicted in Figures 1 and 2, that is, the wing polymer does not form a continuous trim on the core, or adjacent wings are The core surfaces meet, for example, as illustrated in Figures 4 and 5 of US Patent No. 3,418,200. Provided that substantial radial symmetry can be maintained, the wings can be the same or different sizes. In addition, once again, if the radial geometry in the negative direction and the polymer composition symmetry can be maintained, each wing may be a polymer different from the other wing. However, to simplify manufacturing and achieve radial symmetry, the wings are approximately the same size and are preferably made from the same polymer or polymer blend. For ease of manufacture, it is also preferred that the wings discontinuously surround the core. Although the cross section of the fiber is essentially symmetrical in terms of size, polymer, and angular spacing around the core, it should be understood that in any spinning method, due to, for example, uneven quenching or defective polymer melt flow or Defective = the factor of the drawing orifice, and there is a slight variation with perfect symmetry. It should be understood that the extent of this variation of Han You is not sufficient to detract from the purpose of the present invention, such as providing a desired stretch and recovery of fibers through a one-dimensional spiral crest, while minimizing two-dimensional and three-dimensional crimping. In other words, it is not intentional 〇: \ 74 \ 74152-9ll〇18.D〇a -13- 11 V. Description of the invention (knowledge, quasi-made as asymmetric as US Patent No. 4,861,660. ——Different From the core to which it is attached < protruding outwardly, and forming at least partly surrounding the core, a plurality of tired spins A are formed after effective heating. When the fiber is stretched, the pitch of the tired spins can be increased. The fiber of the present invention It has multiple wings, preferably 38, 5 or 6. The number of wings used depends on the characteristics of the fiber: its characteristics and the conditions of its manufacture and use. For example, when manufacturing early filaments, Especially under higher draft ratio and fiber tension, 5 or 6 wings can be used. In this case, the spacing of the wings can frequently surround the core, so that the elasticity can be protected from the rollers, guides, and the like. It is less likely to break, rolls, and wear than when it is in contact with materials. The effect of higher draft ratio and fiber tension is to press the fibers more tightly towards the light and guide, thus extending the wings. And bringing the elastic core into contact with the light or guide; therefore, at high draft ratios and fiber tension More than two wings are preferred. In a monofilament, five or six wings are usually better for the most suitable combination for easy manufacturing and reduced core contact. ♦ When multi-fiber yarn is required, it is because between the elastic core and the roller or guide The contact performance of the fiber is reduced due to the presence of other fibers, so as few as two or three wings can be used. Although the wings preferably discontinuously surround the core for ease of manufacture, the core can be placed on its outer surface Between the points where the wings touch the core: The thickness of the sheath can be within the range of about 0 5% to == of the maximum radius of the fiber core. The sheath can provide more contact points between the core and the wing polymer The #help wing heart adheres to the core 'is a particularly useful feature when the polymers in the bicomponent fibers are not well adhered to each other. The sheath can also be lowered between Pak, guides, and the like.

Beta and t inventions "The core and / or wings of a multi-wing cross section may be solid, or include hollow or two-gap. Typically, the core and wings are solid. Further, the wings may have any shape, such as an oval H, or S-shape (see, e.g., Figure 4). : An example of the shape of a wing is found in U.S. Patent No. 4,3,85,866. The T, c, / shape, as explained above, can help protect the elastic core from contact with the guide and Xing Kun. The weight ratio of the entire wing polymer to the core polymer is altered to impart properties that are adequately mixed, for example, the desired elasticity from the core and other properties such as low viscosity from the wing mouthpiece. For example, a weight ratio of about 10/90 to about 70/3, preferably about 30/70 to about 40/60, a wing to core may be used. Regarding high durability in applications where fibers are not required to accompany yarns (such as knitwear) combined with high stretch, a wing / core weight ratio of about 3 5/65 to about 50/50 is better. For the best adhesion between the core and the wings, typically, the total fiber weight is about 5 weights! The percentage to about 30% by weight can be a non-elastic polymer that penetrates the core 'or an elastic core polymer that penetrates the wings.

Ear percentage is present. Useful polyalkylene hydrocarbons include copolymers and terpolymers of one or more of polypropylene, mu ethylene, polymethylpentane, and ethyl or propylene with other unsaturated monomers. By way of example, it is within the scope of the present invention to include a non-elastic polypropylene wing and an elastic polypropylene core; such fibers are bicomponent fibers.

-When the fiber is stretched and relaxed, the high elasticity of the core allows it to absorb the compressive, torsional and stretching forces produced by the twist of the attached wings. If the adhesion of the two polymers is too weak, these forces will cause their delamination. According to the present invention, mechanical locking of wings and core polymers can be used to improve adhesion and further minimize delamination during fiber processing and use. The adhesion between the core and the wings can be further enhanced by selecting the wing and core composition and / or using adhesion promoting additives to either or both of the polymers. Adhesion promoters can be used on each wing or only on some wings. Thus, individual wings may have different degrees of delamination from the core, for example, some wings may be deliberately delaminated. An example of such an additive is, for example, 5 weight percent nylon 12 based on total wing polymer, namely poly (12-dodecylamine), also known as r 12 "or" N12 ", which can be used in Riisan® "ΑΜΝΟ" is commercially available from Atofina. In addition, a maleic anhydride derivative (for example, a registered trademark of Bynel® CXA-Du Pont de Nemours and Company) or Lotader @ · Otome / C from AtoHna can be used Triester / maleic anhydride terpolymer) is used to improve the elasticity of polyether-amidamine to improve its adhesion to polyamidamine. Another example is the addition of a thermoplastic soluble and soluble (novolac) resin, such as HRJ12700 (Schenectady International), which has a number average molecular weight in the range of about 400 to about 5000, to an elastic (co) polyether. Cool core to improve its adhesion to (co) polyamide wings. The amount of soluble and fusible resin should be in the range of 1-20 weight percent, and more preferably in the range of 2-10 weight percent. Examples of soluble and fusible resins used for this include, but are not limited to, phenol-formic acid, saccharine-peptone, p-butyl phenol-formic acid, p-ethyl benzoate, p-methyl phenol, formaldehyde, p-propyl Phenol-formaldehyde, p-pentol-formaldehyde, p-octylphenol-acetaldehyde, O: \ 74 \ 74152 * 9 U 018.DOQ 4 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)- 22- 580527 A7 B7

The final fiber drawn after relaxation as described below may have a desizing stretch of at least about 20%. Based on the length of the drawn filament before it is wound up, it is better to thermally relax the filament just drawn to about 1-3 5%, so that it can be manipulated with a typical hard yarn. Then, it can be wound up through the winder 130 in FIG. 7 at a speed of 2000 to about 35,000 meters per minute, and up to 4,000 meters per minute, to collect the quenched, stretched and relaxed as needed. Filament. Or if multiple fibers are drawn and quenched, the fibers can be aggregated and interlaced as needed, and then, for example, wound up at a winder 13 at a height of 4000 meters per minute, for example at about 2 per minute Within the range of 0 to about 3500 meters. Monofilament or multifilament yarns can be wound up in the same manner in Fig. 7 < winder 13o. When the multifilament is drawn and quenched, the filaments can be gathered and interlaced as necessary before winding. At any time after stretching, the bi-component filaments can be dried or wet-treated simultaneously and fully relaxed to produce the desired stretch and recovery properties. Such relaxation can be accomplished during the manufacturing of the filaments, for example during the aforementioned relaxation steps, or after the filaments are combined into yarn or fabric, for example during the scouring, dyeing, and the like steps. The heat treatment of the fiber or yarn form can be performed in a light or hot box, or in, for example, a spray screen increase step. This relaxation heat treatment can be done when the fiber is in the shape of a yarn or fabric, so that it can be treated before that moment. It can be processed like a non-elastic fiber: However, if you need to It will be heat treated and fully relaxed before becoming high stretch fiber.

As mentioned before, the spinneret pores have the desired cross-section corresponding to the fibers of the present invention as previously described, or produce other bi-component or bi-component fibers =. As is known in the art, capillary or spinneret drilling can be cut by any suitable method, such as laser cutting (as described in U.S. Patent No. 5,168,143), drilling, electronic discharge machining ( EDM), and punching. Capillary apertures can be cut using a laser beam to better control the cross-sectional symmetry of the fibers of the present invention. The orifice of the spinneret pores can be of any suitable size and can be cut to be continuous (pre-condensation) or discontinuous (post-condensation). Secondly, non-continuous capillary pores are made by drilling small holes in a form that allows the polymer to condense below the spinneret surface and form the multi-wing cross section of the present invention. For example, the filaments of the present invention can be manufactured using a previously condensed spinneret package as illustrated in Figures 8, 8A, 88, and 80. FIG. 8 shows the side elevation of the spinneret ^ combined stacking plate shown in FIG. 7, where the polymer flow is in the direction of arrow F. FIG.

The distribution plate is above the spinneret A, which has a capillary hole that penetrates, but no substantial pillar pit. Aligned with and in contact with it, the spinneret is aligned with and in contact with the spinneret support plate (E) with a larger capillary hole. The arrangement is such that the polymer supplied to the metering plate C can pass through the distribution plate B, the spinneret A, and the spinneret support plate E to form fibers. A melt cell plate D, which is a conventional plate, is used for the supply metering plate. The polymer melt pool plate D and the spinneret combination support plate E are thick and stiff enough so that they can be pressed against each other tightly, thus preventing the polymer from leaking between the stacked plates of the spinneret combination. The plates A, B, and C are thin enough that the aperture can be cut by the laser light method. The hole in the spinneret support plate (E) is, for example, 45. It is better to open at -60 ° so that the fiber just drawn will not touch the edge of the hole. When the polymer is required to coagulate before contacting the polymers (former coagulation) below about 0.30 cm before forming the fibers, generally less than 0.15 cm is also preferred, so that it can be more accurately displayed in the fibers The cross-sectional shape designed by the metering plate C, the optional distribution plate D, and the spinneret design E. A more precise definition of the fiber cross section can also be promoted by cutting the holes through the plate as described in U.S. Patent No. 5,168,143, in which the multi-mode beam from a solid-state laser is reduced to a predominantly single-mode beam ( (E.g. mode), and focus to a point below 100 microns, and 0.02 to 0.3 mm above the metal sheet. The generated molten metal is discharged from the lower surface of the metal sheet by using a pressurized fluid flowing coaxially with the laser beam. The distance from the top of the uppermost distribution plate to the surface of the mouth wire plate can be reduced to less than about 0.00 cm. To make filaments with any number of symmetrically arranged wing polymer portions, the same number of symmetrically arranged orifices are used in each plate.

Fig. 8B shows a complementary distribution plate B having a distribution orifice 15 which is tapered at the open end 152 to a non-essential slit 154 connecting the distribution orifice to the center circle 1156. FIG. 8C shows the metering pores 16 with wing polymer and the metering plate c of% metering pores 62 in the spout. The polymer melt cell plate D may be of any conventional design in the art. The spinneret support plate is large enough, and the path of the filament obtained from the new drawing is opened (for example, at 45-60. Open) so that the filament does not touch the through hole on the side of the hole, as shown in Figure 7 and The side elevation of 8 is π. The stacking board assembly—plates eight to zero—are arranged so that the core polymer flows from the polymer melt pool plate D through the center measuring hole 162 of the metering plate C and the six small capillary holes 164, and then through the distribution plate. The center circular capillary hole 156 of β flows through the spinneret, and the circular capillary hole 42 in the a plate A, and flows out through the large opening hole in the spinneret support plate ε. At the same time, the wing polymer flows from the polymer melt pool plate D through the wing polymer metering pores 16 of the metering plate C, and through the distribution plate B foot distribution orifice 15o (where there is a non-essential slit 154, the two polymers first contact each other), flow through the polymer orifice 14 of the wing of the spinneret A, and finally flow out through the holes in the spinneret support plate E. The spinneret of the present invention can be used to encapsulate a plurality of synthetic polymers by melt extrusion to produce fibers. In the spinneret package of the present invention, since the spinneret does not have a substantial column pit, the polymer can be directly supplied into the capillary holes of the spinneret. The stated pits of the supply and delivery means any length of pits (including any recesses connecting the entrances of multiple pores) which are lower than the pores of the spinneret.
