Definitions
- the present invention relates to a process for preparing an elastic fiber having a high modulus and superior resistance to alkali and heat. More specifically, the present invention relates to a process for preparing a high modulus and highly alkali and heat resistant elastic fiber by adding 1 ⁇ 20% by weight of a cellulose acetate to a polyurethane or polyurethaneurea solution, based on the total weight of the polyurethane or polyurethaneurea, to obtain a spinning solution, and ripening and spinning the solution. According to the process, a high modulus and highly heat resistant elastic fiber can be prepared without a sudden change in conditions for preparation of the polymer.
- an elastic fiber is used in a wide variety of applications.
- the elastic fiber acts to tightly hold a polyester yarn of a 3-way warp knitted velvet fabric, together with a polyester fiber.
- the elastic fiber is required to have a modulus high enough to form and maintain a good raised state, and at the same time, to have heat resistance sufficient to endure dyeing and setting treatments at high temperature in subsequent post-processing steps of a polyester velvet fabric.
- An embossing technique has been recently in the spotlight as a technique for increasing the added value of a velvet fabric. For embossing of various patterns, raised yarns of the velvet fabric must undergo burning-out and printing into a desired color. For the processes, superior alkali resistance is inevitably necessary for the elastic fiber.
- a high concentration alkaline solution e.g., mainly caustic soda solution
- a printing solution is applied thereto, followed by high temperature treatment for dye fixing, the elastic fiber is required to have superior alkali resistance in order to prevent it from being degraded by alkaline solution remaining on the fabric at high temperatures.
- elastic fibers have alkali resistance to some extent due to their inherent characteristics, but are likely to easily degrade when caustic soda at a high concentration of about 25% to about 30% is applied at a temperature as high as 160°C ⁇ 180°C. Accordingly, burning-out and printing processes have been separately carried out. No technique has been established that can simultaneously proceed burning-out and printing processes to date.
- Japanese Patent Laid-open No. 2000-303259 issued to Fujibo discloses a polyurethane elastic fiber having improved moisture-absorbing properties and biodegradability.
- the polyurethane elastic fiber is prepared by adding a cellulose acetate to a polyurethane or polyurethaneurea solution, homogeneously stirring the mixture to obtain a spinning solution, spinning the solution to prepare an acetylcellulose-containing elastic fiber, and treating the acetylcellulose-containing elastic fiber with an alkali.
- the publication does not mention the alkali or heat resistance of the elastic fiber.
- the modulus of the elastic fiber is far too low to solve the above-mentioned problems.
- the present inventors have earnestly and intensively conducted research to solve the above-mentioned problems, and as a result, have found that when 1 ⁇ 20% by weight of a cellulose acetate (diacetate or triacetate) having a degree of acetylation of about 28% to about 72% is added to a polymer solution, based on the solid content (i.e., polymeric components) of the polymer solution, homogeneously stirring the mixture to obtain a spinning solution, ripening the solution for a predetermined period of time, and spinning the ripened solution, an elastic fiber having a high modulus and superior resistance to heat and alkali can be easily prepared without a sudden change in polymerization viscosity or non-uniform physical properties of the fibrous product.
- the present invention is based on this finding.
- a process for preparing an elastic fiber comprising the steps of: adding 1 ⁇ 20% by weight of a cellulose acetate to a polyurethane or polyurethaneurea solution, based on the total weight of the polyurethane or polyurethaneurea, to obtain a spinning solution; ripening the solution for a predetermined period of time; and spinning the ripened solution.
- a high modulus and highly alkali and heat resistant elastic fiber which is prepared by the process.
- the polyurethane or polyurethaneurea solution for use in the present invention is obtained by procedures known in the art. For example, an organic diisocyanate is reacted with a polymeric diol to form a polyurethane precursor. After the polyurethane precursor is dissolved in an organic solvent, the resulting precursor solution is reacted with a diamine for chain extension. The chain extension reaction is terminated by using a monoamine to obtain the polyurethane or polyurethaneurea solution.
- organic diisocyanates usable in the present invention include diphenylmethane-4,4'-diisocyanate, hexamethylenediisocyanate, toluenediisocyanate, buthylenediisocyanate, hydrogenated p,p-methylenediisocyanate, and the like.
- the polymeric diol there may be used, for example, polytetramethyleneether glycol, polypropyleneglycol, or polycarbonatediol, all of which preferably have a number-average molecular weight of 1,750 to 2,050.
- the diamine employed as a chain extender may be ethylenediamine, propylenediamine, hydrazine, or the like
- the monoamine employed as a chain terminator may be diethylamine, monoethanolamine, dimethylamine, or the like.
- suitable organic solvents that can be used to obtain the polymer solution include, but are not particularly limited to, N,N' -dimethylformamide, N,N'-dimethylacetamide, dimethylsulfoxide, and the like.
- the polyurethane or polyurethaneurea solution may further contain at least one additive selected from dulling agents, UV stabilizers, antioxidants, NO x gas anti-yellowing agents, anti-adhesion agents, dyeing promoters, and anti-chlorine agents.
- cellulose acetate 1 ⁇ 20% by weight of the cellulose acetate is added to the polyurethane or polyurethaneurea solution, based on the total weight of the polymer, and the mixture is homogeneously stirred to obtain a spinning solution. If the amount of the cellulose acetate added is below 1% by weight, the addition effect is negligible. On the other hand, if the amount of the cellulose acetate exceeds 20% by weight, homogeneous mixing is difficult.
- the cellulose acetate may be cellulose diacetate or cellulose triacetate, and preferably has a degree of acetylation of about 28% to about 72%.
- the spinning solution is ripened by allowing it to stand at 30°C ⁇ 70°C for 28-38 hours, and is then spun to prepare the final elastic fiber having a high modulus and superior resistance to heat and alkali.
- the steps have a direct influence on the increase of the modulus and improvement in the resistance to alkali and heat of the electric yarn. Accordingly, it is important to set optimized conditions for the steps.
- the cellulose acetate is dissolved in the same organic solvent as that used to obtain the polymer solution, the resulting solution is homogeneously stirred for 7 ⁇ 8 hours, and then the homogeneous solution is added to the polymer solution. Thereafter, the resulting mixture is homogeneously stirred for at least 2 hours. At this time, the stirring time is extended by 30 minutes with increasing percentage of the cellulose acetate added. After stirring, the mixture of the cellulose acetate and the polymer solution is ripened for about 28 ⁇ 38 hours, and is then spun through a spinning nozzle to prepare the final elastic fiber.
- polyurethane precursor 518g of diphenylmethane-4,4'-diisocyanate, and 2,328g of polytetramethyleneetherglycol having a number-average molecular weight of 1,800 were reacted with each other at 85°C for 90 minutes with stirring to form a polyurethane precursor containing isocyanate groups at both terminal positions.

The heat treatment is repeated five times (5 cylces). The heat resistance of the yarn sample is expressed as percentage of the difference between the length ("initial length") of the yam sample before the heat treatment and that ("download value") after the fifth cycle. 2) The alkali resistance of the yarns was evaluated by the following procedure: A yam sample is dipped in an 25% aqueous NaOH (25wt%) solution, and heated to 150°C.
- the alkali resistance of the yam sample is expressed as the time taken for the yarn sample to decompose.
- the power retention of the fabrics was measured by the following procedure: A finally processed fabric is cut into a fabric sample (1 inch x 30cm). The fabric sample is held by grips from Instron Co., so that the length of the fabric sample for measurement is 20cm. The holding is repeated five times (5 cycles). The power retention of the fabric sample is expressed as percentage of the difference between the length ("upload value") of the fabric sample after the first cycle and that ("download value”) after the fifth cycle. 4) The raised state before burning-out was evaluated by visually examining the degree of uprightness of raised yarns after the velvet fabrics were subjected to shearing and background dyeing.
