The present invention relates to a fiber adhesive made of a polyester copolymer, and an object thereof is to provide a fiber adhesive made of a crystalline, low melting point polyester copolymer. Conventionally, many fiber adhesives made of polyester copolymers having a low melting point or a low softening point have been proposed as hot melt adhesives, self-adhesive fibers, and the like. However, products made of amorphous polyester copolymers have good heating and adhesive processability, but
Since the cohesive force was low, the adhesive force was not necessarily sufficient. In addition, those made of crystalline polyester copolymers have a high adhesive strength, but tend to be hard and brittle, and lack flexibility and texture. As a result of intensive studies to overcome this problem, the present inventors have developed a fiber adhesive made of a crystalline polyester copolymer, which is flexible and has a good texture. This heading led to the present invention. That is, the present invention is a copolymerized polyester whose repeating units are composed of β-ethoxy-ethylene terephthalate and tetramethylene terephthalate, in which the acid component constituting it is a terephthalic acid component having no substituents, and the glycol component is 40 of them
~80 mol% is diethylene glycol component 20-60
This is a fiber adhesive made of a polyester copolymer, characterized in that mol% of the component is tetramethylene glycol. In addition, in the present invention, "the repeating unit is β
-Ethoxy-ethylene terephthalate" is the following repeating unit. In order for the polyester copolymer constituting the fiber adhesive of the present invention to be crystalline, the acid component constituting it must be a terephthalic acid component having no substituents. Further, among the glycol components, it is necessary that the diethylene glycol component should be 40 to 80 mol%, and the tetramethylene glycol component should be 20 to 60 mol%. If the diethylene glycol component is less than 40 mol%, the melting point of the polymer will be too high, and if it exceeds 80 mol%, the crystallinity will be significantly reduced. In addition, the tetramethylene glycol component is 20 mol%.
If it is less than 60% by mole, the copolymer will become hard and have a poor feel when used as a fiber adhesive. The polyester copolymer constituting the fiber adhesive of the present invention can be produced in the same manner as in the production of ordinary polyester. In addition, commonly used dissipating agents, pigments, lubricants, nucleating agents, stabilizers, etc. can be added. Furthermore, polyfunctional compounds such as pentaerythritol, trimethylolpropane, glycerin, trimellitic acid, etc., and monofunctional compounds such as benzoic acid, naphthoic acid, etc. may be used as long as the polymer can be considered to be linear. The fiber-like adhesive of the present invention has a low melting point and is useful as a so-called hot melt adhesive that can be thermally bonded. It can be used in any form such as filament, cloth, film, powder, ribbon, tape, or lotion. EXAMPLES The present invention will be specifically described below with reference to Examples. In this implementation, all parts indicate parts by weight. The intrinsic viscosity of the polymer in orthochlorophenol solution is
Calculated from solution viscosity measured at 35°C. The melting point of the polymer is the endothermic peak when the temperature is raised at a rate of 20°C/min using DSC (manufactured by DuPont). Adhesion was evaluated as follows. (1) Preparation of sample film Melt the polymer at 200-250℃, extrude it,
A film of approximately 50μ was slit into a 1cm wide tape to be used as a sample. (2) Adhesive strength The above film sample was sandwiched between two sheets of polyester/cotton (165/35) broad base fabric, adhered under pressure at a predetermined temperature for 10 seconds at a pressure of 0.5 kg/ cm2 , and then peeled off. Strength is used as adhesive force. (3) Dry cleaning resistance The above adhesive sample was washed in Perclean at 50℃ for 10 minutes.
A dry cleaning resistance test was conducted five times, and the adhesive strength after the test was measured. In addition, since texture is difficult to quantify, qualitative expressions such as 〇△× were used, and 〇 was regarded as passing. Example 1 11.7 parts of dimethyl terephthalate, 14.6 parts of tetramethylene glycol, 19.7 parts of diethylene glycol
1 part and 0.016 part of tetrabutyl titanate were charged into a reactor, and a transesterification reaction was carried out at 170 to 200°C. When about 80% of the theoretical amount of methanol was distilled off, the temperature of the system was raised from 200°C to 250°C, and the condensation reaction was carried out under reduced pressure for about 300 minutes. The obtained polymer had an intrinsic viscosity of 0.73 and a melting point of 154°C. The glycol composition in the polymer determined by NMR was 46/54 (molar ratio) of tetramethylene glycol/diethylene glycol. Using this polyester copolymer, adhesive
A 50μ film sample was prepared and an adhesion test was conducted. The results are shown in Table 1.
