Description

The present invention relates to a polyether ester amide composition that has excellent color fastness, antistatic properties, and moisture absorption and desorption properties when made into fibers.

Conventionally, polyether ester amide compositions have been mainly used as antistatic agents for resin molded articles, and are known to impart excellent antistatic properties.

Patent Document 1 discloses an antistatic property consisting of a thermoplastic polymer, a copolymer having a polyamide block and a polyether block, and a polymer or oligomer having at least one type of ionic functional group in the polymer chain. Inhibitory polymer compositions are illustrated. Further, Patent Document 2 describes a thermoplastic polyester with improved color tone by blending polyether ester amide, which is a thermoplastic polyester copolymerized with poly(ethylene oxide) glycol.

Furthermore, Patent Document 3 describes a polyamide of a specific molecular weight, a polyether ester amide derived from an ethylene oxide adduct of a high molecular weight bisphenol as a polyether component, and a specific ratio of this polyether ester amide and a thermoplastic resin. Examples of resin compositions are shown. Further, Patent Document 4 describes a polyamide elastomer that has low hardness, transparency, and hydrophilicity by uniformly polymerizing polyoxyethylene glycol and dicarboxylic acid of a specific molecular weight, and lactam in a specific ratio.

However, although the resin compositions obtained by the methods described in Patent Documents 1 and 2 have relatively high antistatic properties under conditions of a temperature of 20°C and a humidity of 40% RH when made into fibers, they have poor antistatic properties. Because it lacks moisture absorption and desorption properties to retain the moisture necessary for development, its antistatic properties are not at a satisfactory level under low temperature and low humidity conditions (10° C., 10% RH). In addition, the resin composition obtained by the method described in Patent Document 3 uses polyethylene glycol having an aromatic structure as a polyether component in order to improve antistatic properties, and although the antistatic properties are improved, When it is made into fibers, its moisture absorption and release properties are not at a satisfactory level, so its antistatic properties are not at a satisfactory level under conditions of low temperature and low humidity (10° C., 10% RH). In addition, the resin composition obtained by the method described in Patent Document 4 controls the weight fraction of each component in the composition in order to exhibit transparency and hydrophilicity while having antistatic properties. Although it exhibits antistatic properties, its moisture absorption and desorption properties are not at a satisfactory level when it is made into fibers, so its antistatic properties are not at a satisfactory level under conditions of low temperature and low humidity (10°C, 10% RH). .

The resin composition obtained by the method described in Patent Document 5 has moisture absorption and desorption properties and antistatic properties by controlling the molecular weight and molecular weight distribution ((number average molecular weight (Mn)/weight average molecular weight (Mw)). However, the color fading is severe when washed after being made into fibers, and the color fastness is not at a satisfactory level.

The present inventors have discovered a polyether ester amide composition that exhibits extremely excellent moisture absorbing and desorbing properties and antistatic properties, and also exhibits excellent color fastness when made into fibers.

In order to solve the above problems, the present invention consists of the following configuration.
(1) Consists of a dicarboxylic acid component (a), a polyamide component (b) made from lactam or aminocarboxylic acid, and a polyethylene glycol component (c), whose melt viscosity is 100 Pa·s or more at a measurement temperature of 265°C, 200 Pa·s or less, and a polyether ester amide composition having a water-soluble eluting component (WSC) of 10% by weight or less.
(2) The polyether ester amide composition according to (1), wherein the dicarboxylic acid component (a) is an aromatic dicarboxylic acid.
(3) The polyether ester amide composition according to (1) or (2), wherein the polyethylene glycol in the composition has a number average molecular weight of 1,000 to 5,000.
(4) A fiber containing the polyetheresteramide composition according to any one of (1) to (3) as a constituent component.

The polyether ester amide composition of the present invention can provide fibers with excellent color fastness, moisture absorption/release properties, and antistatic properties.

The polyether ester amide composition of the present invention comprises a dicarboxylic acid component (a), a polyamide component (b) made from lactam or aminocarboxylic acid, and a polyethylene glycol (PEG) component (c).

The dicarboxylic acid component (a) of the polyether ester amide composition of the present invention includes aliphatic dicarboxylic acids such as succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, sebacic acid, and dodecanoic acid, terephthalic acid, and isophthalic acid. , aromatic dicarboxylic acids such as 2,6-naphthalene dicarboxylic acid, and alicyclic dicarboxylic acids such as 1,4-cyclohexanedicarboxylic acid, and can be used alone or in combination of two or more. Preferred dicarboxylic acids are aromatic dicarboxylic acids. When aromatic dicarboxylic acids are used, crystallinity increases due to the interaction between benzene rings, and the distance between polymer chains becomes shorter, increasing melt viscosity and exhibiting excellent antistatic properties and moisture absorption and desorption properties. A more preferred aromatic dicarboxylic acid is terephthalic acid. The amount of dicarboxylic acid component (a) in the polyetheresteramide composition is preferably 1 to 10% by weight. More preferably, it is 4.5 to 7.5% by weight.

The polyamide component (b) made from lactam or aminocarboxylic acid in the polyether ester amide composition of the present invention includes lactams such as ε-caprolactam, valerolactam, laurolactam, and undecanolactam, ω-aminocaproic acid, 11- These are aminocarboxylic acids such as aminoundecanoic acid and 12-aminododecanoic acid, and they can be used alone or in combination of two or more. A preferred lactam is ε-caprolactam, and a preferred aminocarboxylic acid is ω-aminocaproic acid. The compositional amount of the polyamide component (b) in the polyetheresteramide composition of the present invention is preferably 34% by weight or more and 59% by weight or less. More preferably, it is 35% by weight or more and 55% by weight or less. When the content is 34% by weight or more and 59% by weight or less, the weight ratio with the PEG component (c) becomes optimal, and excellent moisture absorbing and releasing properties and antistatic properties are likely to be exhibited.

The amount of the PEG component (c) in the polyetheresteramide composition of the present invention is preferably 40% by weight or more and 65% by weight or less. More preferably, it is 50% by weight or more and 60% by weight or less. When the content is 40% by weight or more and 65% by weight or less, the weight ratio with the polyamide component (b) becomes optimal, and excellent moisture absorbing and releasing properties and antistatic properties are easily exhibited. Further, by setting the content to 65% by weight or less, an increase in WSC can be suppressed and the color fastness becomes good.

The number average molecular weight of PEG in the polyetheresteramide composition of the present invention is preferably 1,000 to 5,000. More preferably, it is 1,100 or more and 3,500 or less, even more preferably 1,200 or more and 2,500 or less. When the number average molecular weight is in the range of 1,000 to 5,000, the PEG component in the polymer is optimal for containing water, and therefore exhibits excellent moisture absorption and desorption properties and antistatic properties. Note that the number average molecular weight of the PEG component can be identified by chemical treatment using gel permeation chromatography (GPC).

The molar ratio of PEG component (c)/dicarboxylic acid component (a) in the polyetheresteramide composition of the present invention is preferably 1.10 or more and 1.30 or less. More preferably, it is 1.15 or more and 1.25 or less. Within this range, excellent color fastness is exhibited.

The melt viscosity of the polyether ester amide composition of the present invention at a measurement temperature of 265°C is required to be 100 Pa·s or more in order to have color fastness, antistatic properties, and moisture absorption and desorption properties when made into fibers. It is. Preferably it is 100 to 150 Pa·s. When it is within this range, the polyamide component in the polymer molecular chain is easily crystallized, and the PEG component is stably retained in the polymer, resulting in excellent antistatic properties and moisture absorption/desorption properties. In addition, spinning during fiberization is stabilized, and the core-sheath ratio of the composite yarn is stabilized. When the melt viscosity is less than 100 Pa·s, the polyamide component in the polymer molecular chain becomes difficult to crystallize, and the PEG component is difficult to be retained, so that excellent moisture absorption and desorption properties and antistatic properties are not exhibited. Furthermore, the spinning during fiberization becomes unstable, and the core/sheath ratio of the composite yarn is not stabilized.

When the water-soluble leached component (WSC) of the polyether ester amide composition of the present invention is 10% by weight or less, it exhibits excellent color fastness when made into fibers. More preferably it is 7.5% by weight or less, and still more preferably 5% by weight or less. If the WSC is 10% by weight or less, there will be less unreacted PEG and low molecular weight polyamide components in the polymer, so when it is made into fibers, the amount of polymer elution due to water and sweat will be reduced, resulting in excellent dye fastness. It becomes easier to show. On the other hand, when WSC exceeds 10% by weight, the fixed dyeing agent is eluted together with the water-soluble components, so the color tends to fade and the color fastness decreases.

Further, the following compounds may be contained within the range that does not impair the purpose. For example, antioxidants, heat stabilizers (hindered phenols, hydroquinones, phosphites and their substituted products, copper halides, iodine compounds, etc.), weathering agents (resorcinols, salicylates, benzotriazoles, benzophenone) mold release agents and lubricants (aliphatic alcohols, aliphatic amides, aliphatic bisamides, bisurea and polyethylene wax, etc.), pigments (titanium oxide, cadmium sulfide, phthalocyanine, carbon black, etc.), dyes ( Nigrosine, aniline black, etc.), crystal nucleating agents (talc, silica, kaolin, clay, etc.), plasticizers (octyl p-oxybenzoate, N-butylbenzenesulfonamide, etc.), antistatic agents (quaternary ammonium salt type) Cationic antistatic agents, nonionic antistatic agents such as polyoxyethylene sorbitan monostearate, betaine amphoteric antistatic agents, etc.), flame retardants (hydroxides such as melamine cyanurate, magnesium hydroxide, aluminum hydroxide, etc.) materials, ammonium polyphosphate, brominated polystyrene, brominated polyphenylene oxide, brominated polycarbonate, brominated epoxy resin, or a combination of these brominated flame retardants and antimony trioxide, etc.), fillers (graphite, barium sulfate, magnesium sulfate, etc.) , calcium carbonate, magnesium carbonate, antimony oxide, titanium oxide, aluminum oxide, zinc oxide, iron oxide, zinc sulfide, zinc, lead, nickel, aluminum, copper, iron, stainless steel, glass fiber, carbon fiber, aramid fiber, bentonite, Particulate, fibrous, needle-like, plate-like fillers such as montmorillonite and synthetic mica), other polymers (other polyamides, polyethylene, polypropylene, polyester, polycarbonate, polyphenylene ether, polyphenylene sulfide, liquid crystal polymers, polysulfone, polyether sulfone, ABS resin, SAN resin, polystyrene, etc.).

The polyetheresteramide composition of the present invention can be obtained, for example, by the method shown below.

First, the amounts to be added to the obtained polyether ester amide composition are 40 to 60% by weight of the polyamide component (b) made from lactam or aminocarboxylic acid, 1 to 10% by weight of the dicarboxylic acid component (a), and PEG. Component (c) is added in an amount of 35 to 50% by weight, and the polyamide component and dicarboxylic acid component are reacted to produce a polyamide component having carboxyl groups at both ends. As a manufacturing method thereof, for example, in order to suppress decomposition and deterioration due to oxidation, nitrogen substitution is performed multiple times, and then heating is performed under a nitrogen flow of 0.5 L/min at normal pressure (101.33 kPa). The temperature inside the polymerization vessel during heating is preferably 180°C or higher and 300°C or lower, more preferably 200°C or higher and 260°C or lower. During heating, a ring-opening/polymerization reaction of the lactam occurs, and at the same time, the dicarboxylic acid reacts with the amino terminal groups, and by blocking the terminals, a polyamide having carboxyl groups at both terminals is obtained.

By adding a polymerization catalyst to this polyamide and polycondensing it, the carboxyl groups at both ends of the polyamide and the hydroxyl group of PEG undergo an esterification reaction, thereby obtaining a polyether ester amide composition.

In the production of the polyether ester amide composition of the present invention, the molar ratio ((c)/(a)) of the charged amount of the PEG component (c) to the dicarboxylic acid component (a) is 0.8 or more and 0.9 or less. It is.

Within this range, copolymerization proceeds efficiently and a polyether ester amide composition with a higher degree of polymerization can be obtained in a short time. That is, the unreacted PEG component remaining in the polymer is reduced, and the WSC can be controlled to 10% by weight or less.

Furthermore, in the production of the polyetheresteramide composition of the present invention, PEG having a number average molecular weight of 1,400 to 6,000 is used. By being within this range, WSC and melt viscosity can be controlled within desired ranges, and excellent moisture absorption and desorption properties, antistatic properties, and color fastness can be obtained.

It is preferable to use a titanium-based compound as the polymerization catalyst. By performing polycondensation using a titanium-based polymerization catalyst, the number average molecular weight distribution of the polymer can be further controlled, and a polyether ester amide composition with excellent moisture absorption and antistatic properties can be obtained. It is estimated that the titanium catalyst tends to form a stable structure with the oxygen element of the PEG component due to its steric structure. Therefore, compared to other metal catalyst species, the catalyst can be present more uniformly during the reaction, so it is thought that the length of the obtained polymer chains becomes more uniform and the molecular weight distribution is controlled. Particularly preferred is titanium tetraalkoxide (Ti(OR)4). Examples of the alkyl group (R) include a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an ethylhexyl group, a decyl group, a dodecyl group, and a hexadodecyl group. More preferred is titanium tetrabutoxide.

The addition method of PEG and the polymerization catalyst may be divided into one or more times, and the polymerization reaction is performed under reduced pressure, preferably at 100°C or higher and 280°C or lower, more preferably at 130°C or higher and 250°C or lower. do. When the polymerization catalyst is titanium tetraalkoxide (Ti(OR)4), it is desirable to add it before starting pressure reduction in order to prevent hydrolysis of the catalyst. Moreover, since the polymerization reaction proceeds by removing water produced by polycondensation, it is carried out under reduced pressure conditions of 650 Pa or less. In particular, when the raw material is ε-caprolactam, it is easy to scatter in the vacuum device, so the pressure reduction rate is preferably 10 kPa/min or less. The degree of polymerization of the resulting polyether ester amide composition can be determined by measuring the torque and power of a stirrer installed in a polymerization machine to determine the end point of the reaction.

In order to prevent thermal decomposition of PEG during the polymerization reaction, the polymerization time after addition of the polymerization catalyst is preferably within 3 hours. More preferably, it is within 2 hours and 30 minutes.

After the polymerization reaction is completed, the polyether ester amide composition is pelletized by a known method. However, since this polymer is highly hygroscopic and the strands swell when cooled with water, the strands are taken out onto a cooled belt and cooled in the air. It is desirable to pelletize it after that.

The obtained pellets can be made into fibers by known melt spinning and composite spinning techniques. It is usually used as the core of composite fibers with a core-sheath structure to impart durability. For example, polyamide (sheath part) and polyether ester amide composition (core part) are melted separately, measured and transported using a gear pump, and a composite flow is formed to form a core-sheath structure in the usual manner and then spun. The yarn is discharged from the nozzle, cooled to room temperature by blowing cooling air with a yarn cooling device such as a chimney, oiled and condensed with an oil supply device, entangled with a first fluid entangling nozzle device, taken up roller, It passes through a stretching roller and is stretched according to the ratio of the circumferential speeds of the take-off roller and the stretching roller. Furthermore, the yarn is heat set by a drawing roller and wound up by a winder (winding device).

[WSC]
After pulverizing the composition pellets to a size of 150 μm to 425 μm, 5 g (W0) is weighed into a weighing bottle and dried with hot air at 85° C. for 80 minutes. Then, the chip weight (W1) after drying is measured, and the moisture content of the crushed pellets is calculated according to the following formula.

After filtration, the glass filter is dried with hot air at 75° C. for 16 hours and then vacuum dried at 70° C. and 3 torr for 3 hours, and the weight of the pellets remaining in the glass filter (W3) is measured. Then, WSC is calculated according to the following formula.

(W65) is measured. Then, the weight (W90) of the pellet after being held at 30° C. and 90% relative humidity for 24 hours is measured. Then, it was calculated according to the following formula. ΔMR was rated ◎ when it was 8% or more, ○ when it was 5% or more and less than 8%, and × when it was less than 5%.
MR65 (%) = [(W65-W0)/W0] x 100
