Description of the invention (1) Technical field (please read the precautions on the back before filling out this page) The present invention is related to the non-woven or dense cotton fiber structure, which is short for the polyester heat-adhesion. Composite fiber and its manufacturing method. More specifically, the present invention relates to a heat-adhesive composite staple fiber capable of obtaining a fibrous structure having good size and stability by relatively low-temperature heat-fixing and stably obtaining a fiber structure having a stable size, and a method for producing the same. Prior art has always been to use polyester terephthalate, such as polyethylene terephthalate, as a polyester-based heat-adhesive composite fiber, an isophthalic acid component, or a terephthalic acid component. Composite fibers, such as acid constituents, and amorphous polyesters with no crystalline melting point as outer ring components, can be thermally fixed at a relatively low temperature of 120 to 150 ° C, without the need for high temperature heat treatment to form fiber structures And is widely used. However, such a polyester-based heat-adhesive composite fiber can form the opposite side of a fiber structure at a low temperature. When the obtained fiber structure is used in a high-temperature environment, its dimensional stability is deteriorated and its deformation is large. The inventors of the Ministry of Economic Affairs, Intellectual Property Bureau, and 8th Industrial Cooperative Cooperative printed this inventor. In order to solve this problem and improve the dimensional stability of the heat-adhesive fiber itself, a high temperature elongation or heat treatment test was performed above the glass transition point of amorphous polyester At the temperature, the fibers stuck to each other, and it was found that there was a problem in reeling. Therefore, non-crystalline polyesters, especially non-crystalline polyesters with a glass transition point of 50 to 100 ° C, are used as thermally-adhesive composite fibers with thermally-adhesive components. In fact, their excellent dimensional stability has never been proposed. Too. This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) -4- 591140 Intellectual Property Bureau of the Ministry of Economic Affairs (Industrial and Consumer Cooperatives A7 B7) V. Description of the invention (2) The invention discloses the purpose of the invention, It provides unnecessary high-temperature heat treatment, can be heat-fixed at a relatively low temperature, and is used in a high-temperature environment. It has good dimensional stability, is not easily deformed, and has a high-quality non-woven or dense fiber structure. In order to achieve the above object, the present inventors discovered that an amorphous polyester having a glass transition point of 50 to 100 ° C was used as a thermal adhesive component, and polyalkylene terephthalate The polyester is a fiber-forming component, and at the same time, the effective extension conditions are selected to complete the present invention. That is, in order to achieve the above object, the polyester-based heat-adhesive composite staple fiber of the present invention is obtained with a glass transition point of 50 to 1 0 0 ° C, non-crystalline polyester with no crystalline melting point as a thermal adhesive component, polyalkylene terephthalate having a melting point of 2 20 ° C or more is a thermal adhesive compound of a fiber-forming component Short fibers, with a crimp number of 3 to 40 pieces / 25 mm, a crimp ratio of 3 to 40%, and the following definition of a cotton material shrinkage rate of less than 20% are characterized.

Description of the invention (3) (Please read the precautions on the back before filling out this page) 乂, another object of the present invention is a method for manufacturing polyester thermal adhesive composite staple fiber, which is characterized by Amorphous polyester with a glass transition point of 500 ～ 100t and no crystalline melting point and polyalkylene terephthalate having a melting point of 220 ° C or more are melted and sprayed out, and the composite sprayed yarn After cooling and fixing, Unexpanded composite fibers are wound at a speed of less than minutes, and the composite fibers are attached to a polyester block copolymer having a fiber weight of more than 0.03% by weight, and then extended at a temperature of T ^ ~ (T 2 + 3 0 ° C) The maximum extension ratio at cold time is 0.7 2 ~ 1 · 25 times, and then the shrinkage number is 3 to 40 pieces / 25 mm, and the shrinkage ratio is 3 to 40%, where T ^ is Either the glass transition point of the amorphous polyester or the glass transition point of the polyalkylene terephthalate is higher, and T 2 is the glass transition point of the amorphous polyester. The best form of the invention: The fiber-forming component of the polyester-based heat-adhesive composite staple fiber produced by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is a poly-p-benzene with a glass transition point of 220 ° C or higher. Alkyl dicarboxylate. When the melting point of the fiber-forming component is lower than 220 ° C, it is not only difficult for the composite fiber to be drawn, but also the stability during thermal bonding is reduced. As specific examples of the polyalkylene terephthalate, polyethylene terephthalate or polybutylene terephthalate is preferred. A small amount may be contained within a range that does not impair these characteristics. Copolymerization ingredients or additives for matting agents, colorants, lubricants, etc. Among them, polyethylene terephthalate, which is inexpensive and widely used, is preferred.

Description of the invention (4 On the one hand, it is used as a non-crystalline polyester with heat-adhesive component. The glass transition point is 50 to 100. (: "" Polyester does not have a crystalline melting point. When the polyester has a glass transition point of 50 ° C or lower, the fibers are likely to stick during the extension of the manufacturing method described later, and it is not easy to obtain. A composite fiber with excellent dimensional stability having an area shrinkage of less than 20% is not ideal.

Among them, depending on cost and operation From the viewpoint of sex, π includes terephthalic acid component, isophthalic acid component, ethylene glycol component and two An amorphous copolymerized polyester composed of an ethylene glycol component is preferable. As the heat-adhesive component, a copolymer formed by using the above terephthalic acid component, an isophthalic acid component, an ethylene glycol component, and a diethylene glycol component is used. When polymerizing polyester, it is necessary to set the copolymerization ratio so that the glass transition point is within the above range. The molar ratio of the terephthalic acid component and the isophthalic acid component is preferably in the range of 50:50 to 80:20. On the one hand, the molar ratios of the ethylene glycol component and the diethylene glycol component are arbitrarily selected in the range of 0: 100 to 100: 0. In addition, the polyester-based thermal adhesive compound of the present invention Fiber, heat-adhesive component occupies all or part of the fiber surface (ideally more than 40% of the fiber surface area, especially more than 60%), regardless of its outer ring type, eccentric outer ring type, side-by-side type, Any of the composite forms such as sea-island type, split fiber type, etc. The paper size is applicable.

Description of the invention (5) Yes. Among them, the outer ring type, the eccentric outer ring type, and the side-by-side type are ideal. (Read the precautions on the back before filling in this page.) Second, the heat-adhesive composite staple fiber of the present invention has a crimp number. It must be 3 ~ 40 pcs / 25 mm, and the crimping rate is 3 ~ 40%. When the number of crimps is less than 3/25 mm, or the crimping rate is less than 3%, the entanglement between short fibers is insufficient, Card passing is poor, and high-quality fiber structures cannot be obtained. On the one hand, when the number of crimps is greater than 40/25 mm or the crimp ratio is greater than 40%, the intertwining between short fibers is too large, and the card is difficult to obtain. High-grade fiber structure. The ideal number of crimps ranges from 5 to 25/25 mm, and the range of crimps is from 5 to 30%. The form of the shrinkage may be mechanical shrinkage or three-dimensional shrinkage, and it may be appropriately selected according to the purpose or purpose. There is no particular limitation on the fiber length or single fiber fineness', and it may be appropriately selected and set according to the use or purpose. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In addition to the above-mentioned requirements for the heat-adhesive composite staple fiber of the present invention, it is most important that the shrinkage ratio of the cotton net area is defined as below 20%. Accordingly, when 100% of the composite fiber is blended or blended with other fibers, a fiber structure having good dimensional stability in a high temperature environment can be obtained. When this shrinkage exceeds 20%, a fiber structure having good size stability in a high temperature environment cannot be obtained. A more desirable shrinkage of the cotton web area is 10% or less. < Cotton web area shrinkage rate > It will be made of 100% heat-adhesive composite staple fiber with an area of A 0.

Although the segmented copolymer is extravagant on the surface of the composite fiber, it will not reduce the thermal adhesiveness in this way, and can obtain a fiber structure with excellent mechanical properties. In this way, it can achieve the effect of preventing adhesion and maintaining the thermal adhesiveness. Use oil agents, such as anionic surfactants or their polyhydroxyalkylene-based additions, cationic surfactants, nonionic surfactants, mineral oils, and polysiloxane-based treatment agents cannot be used The ideal polyether polyester block copolymer, especially the dicarboxylic acid component is terephthalic acid component and isophthalic acid component and / or alkali metal salt sulfoisophthalic acid component, the molar ratio is 40: 60 to 100: 0, a polyalkylene glycol having a glycol component of ethylene glycol and a number average molecular weight of 600 to 10,000, copolymerized with 20 to 95% by weight, In particular, it is most suitable for the prevention of adhesion and the stability of aqueous emulsions. However, it can also be used with a small amount of adipic acid, azelaic acid, sebacic acid, dodecanedicarboxylic acid, and 1,4-cyclohexane. Acid components such as dicarboxylic acids, or 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,4-cyclohexanediol, 1, 4-Copolymers of diol components such as cyclohexanediyl diol, etc. In addition, in order to adjust the molecular weight, the polyalkylene glycol has a single-sided end combined with ethers of monomethyl ether, monoethyl ether, and monophenyl ether. It does not matter if it is closed. Polyethylene glycols are also listed, such as polyethylene glycol, ethylene oxide, propylene oxide copolymers, polypropylene glycol, polytetramethylene glycol, etc. Polyethylene glycol is ideal. The adhesion of polyether polyester block copolymers to unstretched fibers must be in accordance with the Chinese National Standard (CNS) A4 specification (210X 297 mm) on this paper scale.

Description of the invention (8) C Please read the precautions on the back Fill out this page again} If the unstretched fiber is 0. 0% by weight or more and less than ο. 0. 3% by weight, the sufficient adhesion prevention effect cannot be obtained during the following elongation. On the one hand, the amount of adhesion is large, The adhesion prevention effect does not increase, and it is appropriate that it is 0.5% by weight. In particular, a range of 0. to 0.3% by weight is appropriate. The method for adhering the polyether polyester block copolymer to the surface of the unstretched fiber is not particularly limited, and any conventionally known method can be used. It is usually administered as an aqueous latex solution. At this time, in addition to the emulsifier that stabilizes the latex solution, @ contains additives such as anti-static agents, smoothing agents, anti-embroidery agents, anti-mold agents, antibacterial agents and the like. The Intellectual Property Bureau of the Ministry of Economic Affairs (industrial-consumer cooperation Du Yin disaster) Secondly, the second point concerning the above-mentioned manufacturing method is the extension temperature. Of course, the extension temperature must be set to T 2 (that is, equivalent to the softening point of the amorphous copolymer ester). ) Above, as well as heat-fixing of polyterephthalate, which is a fiber-forming component, the temperature must be set to be higher than the glass transition point of polyterephthalate. Although the above-mentioned polyether polyester is administered to the surface of the unstretched fiber Even if the block copolymer is an elongation temperature lower than the transfer point of either the amorphous polyester or the polyalkylene terephthalate, it is not possible to obtain a composite staple fiber having excellent size stability and thermal adhesiveness for the purpose of the present invention. In addition, it is also important that the elongation temperature does not exceed T 2 (ie, the softening point of the amorphous copolymer ester) + 3 0 ° C. If the elongation temperature exceeds T 2 + 3 0 t, non- When the crystalline polyester fiber is stuck, when the fiber bundle is fused, it is crimped by the crimper, and the stability of the crimper is deteriorated, which is not ideal. The extension temperature is within the above range, regardless of the extension of the stretch, Or two or more All sections can be extended, and the full extension rate must be extended in cold time. The paper size applies the Chinese National Standard (CNS) A4 specification (2Η) x 297 mmΊ '-11-591140 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 2. Description of the invention (9) The ratio is 0.72 to 1.25 times. When the above-mentioned extension ratio is lower than the cold-time extension ratio of 0.72 times, the dimensional stability when the fiber structure is formed decreases. On the one hand, If it exceeds 1 · 25 times the cold-time stretch ratio, not only the extensibility deteriorates, but the thermal adhesiveness also decreases, which is not ideal. Also, the so-called cold-time stretch ratio is the unstretched taken 5 minutes after spinning. Fibers, at 25 ° F: 65% relative humidity, are stretched at a length of 10cm, at a speed of 5cm / sec. When they cannot be extended any more, the length of the chuck spacing (cm) is divided by the initial length (10 cm). In the present invention, at the higher one of the above-mentioned extension temperature T i (which is the glass transition point of the amorphous polyester and the glass transition point of the polyalkylene terephthalate). ) ~ (T i + 1 0) After cold elongation of 0.7 ~ 1 · 0 times, then (T! + 1 0 t :) ~ T 2 (glass transition point of amorphous polyester) + 3 0 ° C) Extending at a temperature of 1 · 0 3 to 1. 2 5 times can increase the effect of dimensional stability and prevent sticking. In addition, it is particularly effective to use warm water as an extended heating medium. The stretched composite fiber is crimped according to a conventionally known method, with a crimp number of 3 to 40/25 mm, a crimp ratio of 3 to 40%, and cut into a desired length. That is, when the crimping form is mechanical crimping, for example, a press-in crimper is used, and the conditions of the crimping pressure or temperature may be appropriately controlled. On the one hand, when the three-dimensional crimping is performed, the composite structure of the composite fibers or the cooling conditions when the yarn is wound can be selected. The polyester heat-adhesive composite staple fiber of the present invention thus obtained has good dimensional stability and is suitable for fiber structures such as non-woven fabrics or rigid cotton.
