Definitions
- the present invention relates to a polyurethane urethane elastic fiber which has excellent heat-setting properties and can be highly dyed. Furthermore, the present invention relates to a method for producing a polyurethan-rare elastic fiber that also provides excellent elasticity and spinning stability.
- Polyurethane obtained by extending the chain with diamine to a prepolymer at the end of the isocyanate synthesized with polyalkylene ether glycol and excess organic diisocia ⁇ : Elastic fibers are known.
- Polyurethane rare elastic fibers are cross-woven with polyamide fibers and polyester fibers to form foundations, socks, and fibers. It is used as a stretchable material in clothing in various fields, such as textile stockings, swimwear, sportswear, and leotards.
- Polyurethane-rare elastic fibers exhibit a rigid hydrogen-bonding physical cross-link in a hard segment comprising a rare group, and exhibit an excellent elasticity function.
- the product fabric is particularly required to have mold stopping properties, for example, pantyhose, circular knitting for leggings such as tights, and brassier, girdle, swimwear, etc.
- mold stopping properties for example, pantyhose, circular knitting for leggings such as tights, and brassier, girdle, swimwear, etc.
- polyurethane urethane elastic fibers have poor heat-setting properties and do not have a large finish according to the mold, making it difficult to wear.
- the edge of the fabric was curled (the phenomenon of curling round and round), which made it difficult to sew.
- rare groups such as polyurethane elastic fibers (elastic fibers consisting only of urethane bonds) and polyetherester elastic fibers (polyester copolymerized with a polyalkylene ether glycol component) are used.
- Elastic fibers having no polymer are also known as well as polyurethan rare elastic fibers.
- These elastic fibers have excellent heat-setting properties and good die-closing properties of product fabrics, but they do not have a rare-segment dosegment, so they recover more elastically than polyurethane-rare elastic fibers. Inferiority or elastic fatigue ⁇ ! It has the disadvantage that its elastic function tends to be impaired when it becomes large.
- the polyetherester elastic fiber not only has insufficient elongation as an elastic fiber, but also has a large stress change with respect to elongation and tends to feel cramped with body movement.
- these elastic fibers have poor thermal durability, they are used in high-temperature processing such as stretcher outers.
- the elastic fibers in the fabric may sag or break, resulting in impaired aesthetics of the product.Therefore, the heat resistance and stiffness of the polyurethane / rare elastic fibers will be sacrificed. It would be useful in these fields if heat-setting properties could be imparted without doing so.
- Japanese Patent Application Laid-Open No. 3-9791 / 15 discloses a specific polymer prepolymer at the terminal end of an isocyanate.
- Polyurethane-rare elastic fibers based on polyether chain-extended with mixed diamin are disclosed in Japanese Patent Application Laid-Open No. H08-138824, diamin and monoamine.
- To a certain percentage Polyurethane fiber which has been polymerized in the above has been proposed.
- Japanese Patent Application Laid-Open No. 7-15047 discloses a polyurea rare elastic fiber to which a specific alkali metal salt is added at a low concentration.
- the present applicant also discloses a specific polyacrylonitrile in Japanese Patent Application Laid-Open No. 7-3169222.
- Polyurethane to which 1 to 14% by weight of a thermoplastic polymer of either a trimeric polymer, a specific polyurethane polymer, or a specific styrene-maleic anhydride copolymer is added
- a rare elastic fiber and its manufacturing method have been disclosed.
- the effect of improving the heat setability of the conventional polyurethane urethane fiber is seen, it is not satisfactory, and the polyurethane urethane elastic fiber is not only satisfactory. In some cases, the elasticity of the rubber was sacrificed, or the spun yarn was broken, making spinning difficult.
- Polyurethane rare elastic fiber is always mixed with polyamide fiber and polyester fiber and dyed.
- acid dyes are mainly used. Since the polyurethane-rare polymer does not have a dye-staining group for an acid dye, the distribution of the dye to polyamide fibers is the center, and the elastic fibers are hardly dyed.
- disperse dyes are mainly used for dyeing mixed materials with polyester fibers.However, these dyes easily enter elastic fibers, but fall off during reduction washing after dyeing and are almost dyed. Not. Alternatively, the reduction washing may look sweet and dyed, but the dyestuff will fall off from the elastic fiber during washing and dry cleaning, and the overall fastness will deteriorate.
- An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a polyurethane which is excellent in elastic function and heat resistance, has high setability, and has improved dyeability, and is capable of fast dyeing.
- Another object of the present invention is to provide a rare elastic fiber.
- Another important object of the present invention is to provide a polyurethane-rare elastic fiber modified as described above, which has an excellent elasticity function and can be produced under stable spinning.
