Definitions
- the present invention relates to a process for preparing polyurethane and an elastic fabric comprising polyurethane elastic yarns made therefrom and, particularly, to polyurethane prepared by adding diamine of chain extender at a predetermined rate and polyurethane elastic yarns made therefrom having excellent heat settable property.
- the present invention relates to a knitted fabric consisting of the elastic fabric having excellent heat settable property at low temperature and a heat- sensitive fiber such as nylon, silk, wool, polypropylene, rayon and polytrimethylene terephthalate.
- the knitted fabric may be heat-set at low temperature to prevent heat degradation of the heat- sensitive fiber and edge curling of the knitted fabric.
- Polyurethane is customarily prepared by reacting a polyol with an excessive amount of diisocyanate to prepare a prepolymer, dissolving the prepolymer in an organic solvent and then adding diamine or diol of chain extender to the resulting solution and reacting with chain terminator such as mono-alcohol and monoamine to form a polyurethane spinning solution which is then dry- or wet-spun to make the polyurethane elastic fiber.
- chain terminator such as mono-alcohol and monoamine
- the polyurethane fiber is characterized by its high elasticity and widely used in a variety of areas. As its usage has expanded, there is a growing demand for developing extra features of polyurethane fibers.
- polyurethane fibers is heat-set at high temperature during a post-process after knitting and the high temperature causes heat degradation of heat- sensitive fibers such as nylon, cotton, silk, wool, polypropylene, rayon and polytrimethylene terephthalate.
- heat-sensitive fibers such as nylon, cotton, silk, wool, polypropylene, rayon and polytrimethylene terephthalate.
- 5,948,875 disclose processes for improving the heat settable property of polyurethane elastic yarns. Due to the lack of heat settable property at a low temperature, however, heat-sensitive fibers have not been applicable to the processes disclosed in the prior arts. Disclosure of Invention Technical Problem
- the object of the present invention is to prepare polyurethane elastic yarns having excellent heat settable property with appropriate amine.
- the polyurethane elastic yarns are knitted with a heat-sensitive fiber such as nylon, cotton, silk, wool, polypropylene, rayon and polytrimethylene terephthalate.
- the knitted fabric may be heat- set at low temperature to prevent fabric degradation of the heat-sensitive fiber which in turn improves fabric hand value and to provide the knitted fabric without edge curling.
- a process for preparing polyurethane elastic yarns having excellent heat settable property and an elastic fabric made therefrom are produced by reacting polyols with an excessive amount of diisocyanate to prepare a prepolymer, dissolving the prepolymer in an organic solvent and reacting the resulting solution with a chain extender in order to prepare polyurethane elastic yarns, wherein an amount of 1,3-diaminopropane contained in the chain extender is 40 mol% or more based on the total chain extender.
- a process for preparing polyurethane elastic yarns wherein the chain extender further comprises at least one selected from a group consisting of ethylene diamine, 1,2- di- aminopropane, 1,4-diaminobutane, 2,3-butanediamine, 1,5-pentanediamine, 1,6-hexandiamine and 1,4-cyclohexanediamine.
- a process for preparing polyurethane elastic yarns wherein the prepolymer contains 1.56 wt% to 4.29 wt% of isocyanate based on the total prepolymer.
- a knitted fabric may be heat-set at lower temperature after knitting compared to the prior arts. Hence, heat degradation of the heat-sensitive fiber may be prevented which in turn improves fabric hand value. It also prevents edge curling of the knitted fabric. Best Mode for Carrying Out the Invention
- Segmented polyurethane used in the present invention is made by reacting organic diisocyanate with polymer diol to prepare a prepolymer, dissolving the prepolymer in an organic solvent and then reacting with diamine and monoamine.
- Examples of organic diisocyanate used in the present invention may include at least one selected from a group consisting of diphenylmethane-4,4-diisocyanate, 1 ,5-naphthalenediisocyanate, 1 ,4-phenylenediisocyanate, hexamethylenediisocyanate, 1,4-cyclohexanediisocyanate, 4,4'-dicyclohexylmethanediisocyanate and isophorone diisocyanate.
- Examples of polymer diol used in the present invention may include polyte- tramethylen-etherglycol, polypropylene-etherglycol and polycarbonatediol.
- Diamine may be used as chain extender from at least one selected from a group consisting of ethylenediamine, 1,2-diaminopropane, 1,6-hexamethylendiamine and 1,3-diaminopropane.
- the content of 1,3-diaminopropane based on the total chain extender should be 40 mol% or more preferably. If it is less than 40 mol %, the heat settable property of polyurethane elastic yarn considerably deteriorates.
- Examples of amine having one functional group used in the present invention to control molecule weight of polyurethaneurea may include diethyl amine, mo- noethanolamine, dimethyleamine and so on.
- sterically hindered phenolic compounds benzofuran-on compounds, semicarbazide compounds, benzotriazole compounds and polymeric tertiary amine stabilizer may be added in combination into a spinning solution.
- the polyurethane elastic yarns in the present invention may further include additives such as titanium dioxide and magnesium stearate.
- additives such as titanium dioxide and magnesium stearate.
- Heat settable property(%) ⁇ (heat-set length - original length) ⁇ / (stretched length - original length) ⁇ x 100
- Edge curling(%) (the area of triangle being curled/ the initial area of the triangle) x
- the solid additives to the solution may include 1.5 wt% of ethylenebis(oxyethylene)bis-(3-(5-ter-butyl-4-hydroxy-m-toyl)-propionate), 0.5 wt% of 5,7-di-t-butyl-3-(3,4-dimethylphenyl)-3H-benzofuran-2-one, 1 wt% of l,l,r,l'-tetramethyl-4,4'-(methylene-di-p-phenylene)disemicarbazide, 1 wt% of poly(N,N-diethyl-2-aminoethyl methacrylate) and 0.1 wt% of titanium dioxide to produce a polyurethane spinning solution.
- a circular-knitted fabric was made using a circular-knitting machine(Mayer Co.) with 38 inches cylinder diameter, 28 gauge and 120 feeder.
- the nylon used in preparing the knitted fabric is 70 denier nylon and knitted with 40 denier of elastic yarns produced by the process, and the content of the elastic yarns is 8 wt% based on the total fabric weight.
- Example 4 to 6 and Comparative Example 1 to 3 were carried out as in Example 1, except the changes in the weight percent (wt%) of isocyanate, the type and mol percent(mol%) of chain extender as shown in Table 1.
- Example 7 to 10 were carried out to produce a circular-knitted fabric with elastic yarns prepared in Example 1 and nylon, and Comparative Example 4 to 6 were carried out with elastic yarns prepared by Comparative Example 1 and nylon. They were then treated under the heat-setting conditions shown in Table 2. The edge curling(%) and fabric hand value of the resulting fabric are shown in Table 2.
- the polyurethane elastic yarns of the present invention show excellent heat settable property at low temperature. Therefore, the fabric comprising the elastic yarns prepared in the present invention do not cause edge curling with the heat-set process at low temperature, which resulted in excellent fabric hand value of the resulting knitted fabric available in various areas.
