Field of the Invention The present invention relates to improved comfort. Its method is to use polyester fibers with scallop oval cross-sections and Chain agents are modified to provide a single-strand denier blend of a cationic dyeable copolymeric composition that is capable of being simultaneously stretched; and methods related to these stretches and products made therefrom. BACKGROUND OF THE INVENTION Polyane has been commercially manufactured on a large scale for processing into shaped articles such as fibers', which are mainly made of poly (ethylene terephthalate). Synthetic poly yarns have been around for decades and have been in commercial use. 'Originally proposed by Carloser (WH CarotherM in U.S. Patent No. 2,071,251, ... and then in U.S. Patent No. 2,465,3, 19' Finnfi and Dick Whinfield and Dickson proposed poly (ethylene terephthalate), which is the most widely manufactured synthetic polymer and has been used to date for textile fibers, and is often referred to as homopolymer PET. Homopolymer The pet is generally better than the copolymer because of its low cost, and because of its sufficient properties, it is even better for most end-use applications. However, it is known that the homopolymer PET requires special dyeing conditions (requires High atmospheric pressure), but for example, Nylon fiber is not required, so for some applications, copolyesters have been suggested and used commercially, such as' Griffing and Remington (Griffing and Remington) in the US patent No. 3,018,272 and Hansen et. Al. In U.S. Patent Nos. 5,171,309 (DP-6335) and 5,250,245 (DP-6335-B) have disclosed cationic dyeable copolyesters. Polyester fibers are not (1) Continuous filaments are discontinuous Dimension, the latter is often called short fiber or cut fiber, and it is first formed into continuous polyester filaments by extrusion, which is processed into continuous polyester filament bundles before being converted into short fibers to produce ° continuous polyester filaments The important stage of processing is "drawing" to improve the orientation of the long-chain polyester, and improve the properties of the fiber. -4- The silk scale depends on the towel iii (cNST ^ (⑽χ297-" 木木) III Order I —.1 Γ — '^ (Please read the notes on the back before filling out this page) 4389 2 0 A7 _______ B7 V. Description of the invention (2) Most of the goals of synthetic fiber manufacturers are to replicate the advantages of artificial fibers Nature; these natural paper dimensions are most commonly seen in cotton and wool fibers. Most polyester segment fibers are homopolyester PET with a circular cross section and mixed with cotton. Homopolymer PET is hydrophobic. Cotton absorbs water, and so far most people prefer cotton over synthetic polymer wovens because they believe that many cottons are more comfortable to wear than most woven fabrics made of most synthetic polymer fibers; these synthetic polymers Fiber most The circular cross section previously described. The j | j-shaped cross-section filaments are the most economical synthetic filaments that are the easiest to spin and dye. This is why virtually all synthetic filaments have a circular cross-section, except for the surface area. Add special filaments that are more expensive to manufacture and dye more expensive. For several years, homopolymer PET fibers with a general scallop elliptical profile with grooves along the fiber length have been available on the market from DuPont. Polyester fibers have the added comfort provided by a (non-circular_) cross-section, providing a clear advantage over cotton and circular cross-section homopolymer PET fibers, and the longitudinal grooves provide advantages over the circular cross-section fibers. The advantage of increased water absorption, and the fact that water is wicked along the fiber instead of being absorbed, is the opposite of cotton. However, according to the present invention, the essentials and further advantages are obtained.

Description of the invention (3) --- Degrees of polyester filaments with grooved scallop elliptical cross section, and higher monofilament denier and lower monofilament with specific range It is a mixture of denier filaments and is suitable for processing on carded spinning or spinning systems. In addition to the tow suitable for adding X treatment to carded spinning or woolen wool systems, it is also necessary to provide polyester fibers that can be processed on the spinning system, such as poly I fibers processed in completely different ways> Cotton systems Processing is performed on cut short polyester fibers, and of course cotton; this cotton is a natural fiber with a length similar to cut polyester short fibers. Staple fiber, as opposed to being processed on a spinning or carding system, is usually sold and packaged as a pick-up. After the bale is opened, the fibers can be conveyed to the carding (wool) machine by pneumatic or mechanical system. The carding (hair) machine opens the fiber head and adjusts it into the parallel fiber weaving. In the process, a continuous sliver is formed when leaving the carding (hair) machine. The sliver can then be blended with other fibers such as cotton on a draw frame and passed through one or more additional draw frames to improve blending and uniformity along the ends. The sliver is then spun into yarn on a spinning system, such as a free-end worsted machine 'air-jet worsted machine or a ring spinning machine. In some cases, the sliver from the draw frame is converted into a roving before the ring spinning machine spins the yarn to further reduce the sliver weight to produce a suitable size (count) and a comparable twist, and then weaving Into cloth. As disclosed in U.S. Patent No. 5,591,523 (DP_6255), different monofilament denier (dpf) filaments (typically scallop elliptical cross-sections) are required, and this example is surprisingly shown in Example 1, where In the same spinning machine, it is possible to spin unstretched homopolymer (ethylene terephthalate), which has been spun from significantly different denier, without adjusting the natural stretch I dagger * (modified by tetraethyl orthosilicate) Then, the intimate mixture of these spinning fibers in the same tow is simultaneously stretched at the same stretch ratio to provide excellent properties of the filaments.

As shown, the preparation of polyester polymers and filaments from them are generally disclosed in the art.

Mixtures of polyester fibers with generally scalloped oval cross-sections having grooves along the length of the fiber have long been disclosed in U.S. Patent No. 5,59 1,523. Such mixtures are specifically described as a mixture of high denier and low denier. According to the present invention, the copolymerized vinegar fiber should be a fiber with higher monofilament denier and a fiber with lower monofilament denier.

Description of the invention (6) The compound 'wherein the higher monofilament denier should be at least equal to 4 times lower than the lower denier; the monofilament denier is often referred to as dpf in the following. According to the invention, the mixture of denier beta (sometimes referred to as It is a double denim), as described below, which can provide woven fabrics (comfort, while Dan-like woven fabrics, which are similar to the fan-shaped circular cross section). Although the present invention is not limited to any theory, It is believed that the double kane fibers of the present invention are more wicking because there is a larger space between adjacent fibers. They will not be closely packed together, and fibers with similar sections but the same dpf will be 'because not all of the fibers of the present invention Belonging to the same dpf. I have demonstrated in the following examples that the ratio of high and low dpf fibers and the change of high: low dpf ratio are improved. However, it is better High: The ratio of low dpf should not be too large, especially not more than about 5 _ 1. As for the amount of 低 and low dpf fiber, it can be calculated based on the relative number or relative weight of fibers. As can be seen in Example 2 below, it is light: Heavy fiber count ratio of 2: 1 (dpf ratio of 1: 2) will make the fabric lighter on WVT (water vapor transmission rate) and moisture%: heavy fiber count ratio is almost 4: 1 and more The higher is obviously improved, so it is generally better to use a small quantity ratio, preferably about 3: 1 or lower, although it is recognized that other considerations, such as the dpf ratio, will also affect these results, including yarn length And weaving structure. However, Example 2A has shown that even if the light: heavy quantity ratio of 10.5: 1, after two hours, the WVT and water content ratio will be significantly improved compared to the single dpf comparative example. For the sake of convenience, the example Shows the so-called "nominal Danny", because many people are not used to thinking of yarns, yarn bundles or other fibers with mixed Danny, "Nominal Danny" is the total Danny of the fiber bundle Divided by the total number of tows, yarns, or other tows of the fibers referred to here. Recently, Weaving operators are increasingly interested in low dpf (lower than those available in natural virgin cotton), including in particular sub-denier fibers. Textile operators generally prefer dpf less than about 3 dpf (3 · 3 (Fentex)), but the present invention is also applicable to the blending of any dff copolyester fiber-9- This paper method is applicable to the Chinese National Standard (CNS) A4 specification (210 × 297 mm) ---- iL ___ Μ- --Installation ------ Order ------ (Please read the precautions on the back before filling in this tile) Printed by the Consumer Cooperative of the Central Samples Bureau of the Ministry of Economic Affairs 4389 2 0 A7 B7 ---- -V. Description of invention (7). As for the fiber profile, any profile that is generally round in the shape of shoulders is applicable. U.S. Patent No. 5,59 1,523 describes most of these sections with 4 grooves along the length of the fiber. The fiber surface with 4 grooves has been issued by Gorafa many years ago. U.S. Patent No. 3,914,488, and others including Frank Lin and Clark et al., Were disclosed in U.S. Patent Nos. 4,707,467 and 4,634,625, about 10 years later, respectively. Fibers with 6 and 8 grooved scallop elliptical cross sections have been disclosed in U.S. Patent No. 5,626,96 1 and Application No. 08 / 778,462 (application filed on July 3, 1997 and approved) (Aneja, respectively) DP-6365A and Roop DP-65 50), and these scallop oval fiber cross sections are also considered to be suitable for inclusion in the present invention. Mixtures of different profiles are also expected to provide increased comfort, particularly mixtures of scalloped oval profiles with different numbers of grooves, and are also encompassed by the present invention. The aspect ratio in the circular section of the scallop picking-generally should be at least 1 · 3 ′ 1 to be sufficiently different from the circular fiber. As the aspect ratio increases, the benefits of the scallop sugar circular profile may disappear, so the aspect ratio is generally preferably as high as about 3: 1. It should be understood that this may depend on other factors, such as the number of grooves. Similarly, the groove is not in the general scallop elliptical cross section of the elliptical short axis. It is generally better for certain applications (for example, unlike peanut-shaped profiles). The groove ratio here is calculated as the minimum thickness of the filament section (that is, the thickness of the bottom of the groove on the reverse side of the section divided by the maximum thickness of the section of the adjacent convex portion of the section, for example, U.S. Patent 5,626,96 cited above).

Unlike this modified homopolymer PET, the fibers of the present invention are cationic. The dyeable copolyester composition can be present because of the presence of about 1 to about 2.5 mole% 5-sulfonic acid isophthalic acid metal salt.
