Definitions
- the present invention relates to an oligomer removing agent that is suitable for polyester-based fiber materials that are polyester fiber materials and composite materials of polyester fiber materials with other fiber materials.
- Polyester-based fiber materials that are polyester fiber materials and composites thereof with other fiber materials are usually dyed under high temperature conditions of 100-140° C., but polyester oligomers cause various troubles by eluting from the polyester-based fiber material onto the fiber surfaces or into the dyeing bath.
- the serious problems that are faced are shadow spots or calender contamination that occur when the polyester-based fiber material is a fabric, and powder generation or winding yarn breakage that occur when it is a yarn.
- methods have been adopted that involve adding oligomer removing agents to the dyeing bath or to the reduction/cleaning bath after dyeing. For example, Japanese Unexamined Patent Publication No.
- 2000-154466 discloses a method for preventing trouble resulting from oligomer deposition, by adding to the dyeing bath an oligomer removing agent comprising a sulfonic acid salt of polyoxyethylenestyryl phenyl ether, and a carboxyl group-containing polymer such as an acrylic acid or methacrylic acid polymer or a salt thereof. Also, Japanese Unexamined Patent Publication No.
- 2001-295136 discloses a method for preventing oligomer elution wherein during the dyeing step there is added to the dyeing bath an oligomer preventing agent comprising an ester of a polyhydric alcohol-alkylene oxide addition product and an alkyl or alkenyl fatty acid, or an ester obtained by transesterification between a polyhydric alcohol-alkylene oxide addition product and a natural animal or vegetable fat or oil containing an alkyl or alkenyl fatty acid.
- the polyester oligomer removing effect is low even with addition of such oligomer removing agents or preventing agents, and it is not possible at the current time to achieve a satisfactory oligomer removing effect, especially with acidic baths.
- the present inventors have discovered that the problem of oligomer deposition in the dyeing step for polyester-based fiber materials can be overcome by using as the oligomer removing agent a polyester copolymer obtained by polycondensation between a dibasic acid component comprising a sulfonate group-containing dibasic acid in a specified amount and a dihydric alcohol component containing polyethylene glycol in a specified amount, and have completed this invention on the basis of this discovered knowledge.
- the invention provides an oligomer removing agent for polyester-based fiber materials, characterized by comprising a polyester copolymer which is obtained by polycondensation of a dibasic acid component containing 15-65 mol % of a sulfonate group-containing dibasic acid and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500, and which has a 200° C. melt viscosity of 5000-23,000 mPa ⁇ s and has 10-40 mass % polyoxyethylene chain in the molecule.
- the oligomer removing agent of the invention is polyester copolymer-based, it has high affinity with polyester oligomers and allows oligomers to be stably maintained in water. Moreover, since the oligomer removing agent of the invention contains a sulfonate group, the oligomers do not become redeposited on the fiber material or dyeing machine, and therefore the agent can be suitably used in dyeing steps.
- the oligomer removing agent of the invention comprises a polyester copolymer obtained by polycondensation of a dibasic acid component containing 15-65 mol % of a sulfonate group-containing dibasic acid and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500.
- a dibasic acid component containing 15-65 mol % of a sulfonate group-containing dibasic acid and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500.
- sulfonate group-containing dibasic acids there may be mentioned metal salts of sulfoterephthalic acid, 5-sulfoisophthalic acid and 4-sulfophthalic acid, as well as their ester derivatives such as dimethyl esters, diethyl esters and diphenyl esters.
- the content of the sulfonate group-containing dibasic acid in the dibasic acid component is in the range of 15-65 mol %.
- the polyester oligomer removing power will be impaired if the sulfonate group-containing dibasic acid is present at less than 15 mol % in the dibasic acid component. This is believed to be because a low sulfonate group content lowers the oligomer dispersibility, leading to redeposition of the oligomer in the fiber material.
- dibasic acids other than sulfonate group-containing dibasic acids in the dibasic acid component used for copolymerization there may be mentioned aromatic carboxylic acids such as terephthalic acid, isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid, diphenoxyethanedicarboxylic acid, ⁇ -hydroxyethoxybenzoic acid and p-hydroxybenzoic acid and aliphatic carboxylic acids such as adipic acid, sebacic acid, maleic acid and succinic acid, and there may also be used their acid anhydrides or ester derivatives thereof with lower alcohols or glycols.
- aromatic carboxylic acids such as terephthalic acid, isophthalic acid, naphthalenedicarboxylic acid, diphenyldicarboxylic acid, diphenoxyethanedicarboxylic acid, ⁇ -hydroxyethoxybenzoic acid and p-hydroxybenzoic acid and aliphatic carb
- the oligomer removing agent of the invention further contains polyethylene glycol with a molecular weight of 900-3500, as a dihydric alcohol component, in a different starting material for synthesis of the polyester copolymer to be used in the agent.
- a molecular weight of less than 900 for the polyethylene glycol will tend to lower the oligomer removing power, while a molecular weight of greater than 3500 will tend to impair the dispersibility of the disperse dye.
- the polyester copolymer also contains 10-40 mass % of polyoxyethylene chains deriving from the polyethylene glycol.
- a polyoxyethylene chain content of less than 10 mass % will tend to reduce the removing power of the oligomer, while a polyoxyethylene chain content of greater than 40 mass % will tend to increase the frequency of problems such as insufficient disperse dye dispersibility and high foamability during the dyeing process.
- Ethylene glycol is preferred as a dihydric alcohol other than the polyethylene glycol in the dihydric alcohol component used for synthesis of the polyester copolymer, but there may also be used aliphatic or aromatic diol compounds including C3 or greater alkylene glycols, neopentyl glycol, bisphenol A, bisphenol S and the like.
- the polyester copolymer used for the oligomer removing agent of the invention preferably has a 200° C. melt viscosity of 5000-23,000 mPa ⁇ s.
- the 200° C. melt viscosity may be measured using a CV-1S cone-plate viscometer by M.S.T. Engineering, selecting a cone type and rotation rate suitable for the melt viscosity, based on the manufacturer's instruction manual.
- a melt viscosity of less than 5000 mPa ⁇ s will tend to reduce the polyester oligomer removing power, and may lower the affinity of the oligomer removing agent with the polyester-based fiber material.
- the oligomer removing agent of the invention that comprises a polyester copolymer satisfying the conditions including the sulfonate group-containing dibasic acid content, the content of polyoxyethylene chain from polyethylene glycol with a molecular weight of 900-3500 and the 200° C. melt viscosity, is characterized by exhibiting an excellent ability to remove oligomers from polyester-based fiber materials and minimizing their redeposition onto polyester-based fiber materials and dyeing machines. From the standpoint of handleability, the oligomer removing agent of the invention is preferably used as an aqueous dispersion or emulsion containing the polyester copolymer at 10-50 mass %.
- the process for producing the polyester copolymer of the invention may be any conventional process such as transesterification or direct polymerization, without any particularly restrictions.
- polyester fiber materials from which oligomers are to be removed using the oligomer removing agent of the invention there may be mentioned polyester fiber materials composed of polyethylene terephthalate, polybutylene terephthalate, polypropylene terephthalate, polytrimethylene terephthalate and their copolymers, or composite fiber materials composed of these polyester fiber materials in combination with other synthetic or natural fiber materials, while the form of the fiber material may be a yarn, knitted fabric, woven fabric, nonwoven fabric or the like.
- the dyeing process used for dyeing of the polyester fiber material or composite fiber material using the oligomer removing agent of the invention may be an immersion process which may include jet dyeing, cheese dyeing, beam dyeing, Obermaier dyeing, high-pressure injection dyeing or the like, but any process may be employed without any particular restrictions so long as it allows the object of the invention to be achieved.

- a scoured polyester knit was wrapped around the holder of a CARAPET (Nihon Senshoku Kikai Co.) and anchored above and below with rubber bands, and this was dyed under the conditions described below with addition of one of the oligomer removing agents of Examples 1-16 or Comparative Examples 1, 3, 4 and 6-8, after which the extent of casing spots left on the polyester knit was visually observed and the dye dispersibility was evaluated on a 5-level scale, from 5 (no casing spots) to 1 (numerous casing spots).
- CARAPET Non Senshoku Kikai Co.
- polyester satin woven fabrics dyed under the same dyeing conditions as in the oligomer removing power test described above were dried at 120° C. for 1 minute and then heat treated at 180° C. for 30 seconds. After then cooling to room temperature, a single drop of water was dropped onto the fabric and the time until complete permeation of the water drop from the fabric surface was measured. A lack of water absorption is judged as a lack of persistence of the oligomer removing agent.
