Description
United States Patent Office 3,639,513 Patented Feb. 1, 1972 US. Cl. 260-878 R 5 Claims ABSTRACT OF THE DISCLDSURE A dyeable polypropylene fiber comprising polypropylene in admixture with a copolymer composed mainly of vinylpyridines and alkyl acrylates or alkyl methacry lates having an alkyl group containing 16 to 20 carbon atoms, and a process for dyeing said fiber, characterized in that the fiber is treated with phosphite esters or alkylphenols to make the fiber excellent in fastness to light.
This invention relates to polypropylene fibers having improved properties, particularly excellent dyeability and adaptability as textile fibers, and a process for dyeing such fibers.
As is well known, crystalline polypropylene has excellent physical and chemical properties and is useful as material for preparing fibers and films. On the other hand, however, it suffers from such drawbacks that, due to, however, crystalline polypropylene is low in afiinity for dyes and is ditiicultly dyeable, and thus the utility thereof has been restricted.
In order to overcome the above drawbacks, there have heretofore been proposed various processes. For example, as a process for coloring polypropylene, there has been adopted a dope dyeing with pigment. This method, however, is greatly restricted in variety and, brightness in colors of the resulting colored fibers. Further, as processes for improving the dyeability of polypropylene, there have been proposed many methods. For example polypropylene is admixed with a dyeable polymer, e. g. polyamides, polyesters, or vinylpyridine polymers, or with metal-containing organic compounds. However, because of the incompatibility of these agents with polypropylene fibers obtained according to the above methods suffer from such drawbacks that the fibers are broken during the Spinning and stretching process; that the fibers cannot be dyed to deep shade; that the incorporated dyeability-improving these agents dissolving out during dyeing and scouring steps to make it impossible to obtain dyed fibers bright in color as well as to redye the fibers.
In order to overcome the above drawbacks, US. Pat. 3,156,743 has proposed a method in which a polymer of alkyl acrylates or methacrylates having an alkyl group containing 1 to 12 carbon atoms or a copolymer of said acrylates with vinylpyridines or acrylamides mixed with polypropylene and spun to obtain a dyeable fiber. The fiber obtained according to the above method has considerably favorable dyeability for disperse dyes, but in dyeing with acid dyes, the added polymer dissolves out into the dye bath, with the result that not only the fiber is lowered in dyeability but the dyed fiber is poor in color depth and brightness.
In an attempt to overcome such drawbacks, the present inventors made various studies to find that the polymer to be mixed with polypropylene should have such properties as mentioned below.
That is, the polymer should be one which has a proper hydrophilic and hydrophobic property, shows excellent afiinity for acid dyes, has proper compatibility with polypropylene, and does not deteriorate the excellent properties inherent to polypropylenev Further, the polymer should be one which, in a fiber obtained by spinning and stretching a mixture of polypropylene and the polymer, can take such a form which is macroscopically homogeneously dispersed in the polypropylene while, microscopically, it has distributed in a heterogeneous state. That is, the incorporated polymer itself should form a continuous micro-fibril structure in the polypropylene. In addition, when viewed from the standpoint of mechanical properties and texturizability of the polymer should be one having such a structure as to provide an interaction sumcient to transmit a stress externally applied to the fiber.
As the result, the inventors discovered the following facts:
In case a polymer of the conventionally known alkyl acrylates or methacrylates having an alkyl group containing 1 to 12 carbon atoms, or a copolymer of Said acrylates and vinylpyridines or acrylamides are used as a dyeabilityimproving agent for polypropylene, the polymer and the polypropylene tend to separate from each other during heating and melting due to insufficient compatibility between the two, and, in the extruded filament, the polymer and the polypropylene liable to be peeled each other owing to drafting or stretching during spinning in fiber forming. Consequently, in the resulting fiber, the polymer is in an unhomogeneously dispersed state and does not form continuous microfibril, so that the fiber is lowered in dyeability due to dissolving-out of the dyesite into the dye bath; the dyed fiber is lowered in color-depth and brightness; a texturized fiber obtained therefrom is deteriorated in crimpability and crimp stability, and a knit or woven product thereof is also deteriorated in such fiber property as dimensional stability and the like. In contrast thereto, when the copolymer employed in the present invention, which is composed mainly of a vinylpyridine and alkyl acrylates or methacrylates having alkyl group containing 16 to 20 carbon atoms, is used as a dyeability-improving agent for polypropylene, the compatibility of the copolymer with the polypropylene is greatly improved and therefore, in the resulting fiber, the copolymer is homogenous dispersed macroscopically, and is heterogeneously dispersed microscopically, and forms a continuous micro-fibril structure. Further, in dyeing the fiber with acid dyes, the copolymer swells in an aqueous dilute sulfuric acid solution employed as the dye bath but does not dissolve even at the boiling point of the solution, with the result that not only the fi ber can be dyed into a deep shade, but also the dyed fiber is excellent in color-depth and brightness. Furthermore, the fiber shows excellent mechanical properties and texturizability, by virtue of such a favorable fiber structure as mentioned above, and the crimpability and crimp stability of texturized fiber and the dimensional stability of knit or woven product thereof are markedly excellent, as well.
It has further been found that when the copolymer comprizing an alkyl methacrylate having an alkyl group containing 16 to 20 carbon atoms is used, a part of the copolymer added to polypropylene causes local degradation during spinning, and the use of said copolymer is somewhat inferior in fiber properties to the case where the alkyl acrylate copolymer is used. In order to effectively achieve the present invention, the use of the alkyl acrylate copolymer is preferable.
Based on the detailed knowledge as mentioned above, the present inventors made earnest studies to accomplish the present invention, the gist of which resides in that polypropylene is mixed with a copolymer composed mainly of a vinylpyridines and alkyl acrylates or methacrylates having an alkyl group containing 16 to 20 carbon atoms.
The first object of the present invention is to provide a polypropylene fiber excellent in dyeability and in dye fastness properties, particularly fastness to light.
The second object is to improve the texturizability of said polypropylene fiber.
The third object is to provide a process for dyeing the dyeable fiber of the present invention, characterized in that the fiber is treated, either before, during or after dyeing, with a solution or emulsified dispersion containing at least one member selected from the group consisting of specific phosphite esters and alkylphenols, thereby the fastness to light of the dyed fiber is greatly improved.
In accordance with the present invention, there are provided a deyable polypropylene fiber and a process for dyeing said fiber, characterized in that polypropylene is mixed with 130% by weight based on the total polypropylene composition of a copolymer composed mainly of vinylpyridines and alkyl acrylates or methacrylates having an alkyl group containing 16 to 20 carbon atoms, and the mixture is subjected to shaping or the mixture is further incorporated with at least one member selected from the group consisting of nonionic surface active agents and/or polyethers, or at least one of specified phosphite esters, and then the mixture is subjected to shaping.
In practicing the present invention, the copolymerization of vinylpyridines with alkyl acrylates or methacrylates having alkyl group containing 16 to 20 carbon atoms may be effected according to any of the conventionally known suspension polymerization, emulsion polymerization, and bulk polymerization. The polymerization is desirably effected in the presence of a polypropylene powder.
Copolymer suitable for the objects of the present invention is one comprising 85-30% by weight of vinylpyridines and -70% by weight of an alkyl acrylates or methacrylates having alkyl group containing 16 to 20 carbon atoms and having a reduced viscosity (1 C:O.5 g./ 100 ml., same shall apply hereinafter) of 2.0 or less as measured at C. in a 9:1 benzene-alcohol mixed solution. However, the preferable range of the reduced viscosity of the copolymer varies depending on the molecular weight of the polypropylene to be mixed with said copolymer, and in case a high molecular weight polypropylene has been employed, a copolymer having a reduced viscosity more than 2.0 is sufficiently applicable, as well.
In case the copolymer contains more than 85% by weight of vinylpyridines, the copolymer is lowered in compatibility with polypropylene and is present in a fine granular form in the resulting fiber to make impossible the formation of micro-fibrils. Consequently, in dyeing the fiber with acid dyes, the copolymer is dissolved out into the dye bath, whereby not only the dyed fiber is deteriorated in color depth and brightness but also no fiber excellent in mechanical properties and texturizability can be obtained.
The amount of the coploymer in the present invention is most preferably 1-30% by weight based on the total polypropylene composition. In case the amount of the copolymer is less than 1%, no sutficient dyeability-improving effect can be attained, while in case the amount is more than 30%, the resulting fiber is undesirably deteriorated in efliciencies particularly fiber property and texturizability.
The objects of the present invention can be more effectively achieved by use of a ternary copolymer obtained by copolymerizing ethyl or methyl acrylate. That is, by copolymerization of a small amount of ethyl or methyl acrylate, the copolymer employed in the present invention is made easier in the formation of micro-fibrils having influence on the physical properties of the resulting polypropylene fiber. Therefore, when said ternary copolymer is used in the production of a crimped yarn, erg. a woolly texturized yarn or a textured yarn obtained by conjugate spinning, the crimped yarn is favorable in crimpability and crimp stability for the reasons mentioned above. Particularly in the production of a crimped yarn according to conjugated spinning, the use of other c0- polymer than that of the present invention results, due to insutficient compatibility with polypropylene, in such disadvantages that the copolymer does not uniformly disperse in the resulting fiber nor forms micro-fibrils. Consequently, the crimped fiber obtained sufiers from such drawbacks that the dyesite falls oif during dyeing to lower the dyeability of the fiber and the color depth and brightness of the dyed fiber. Moreover, due to insufficient compatibility of the copolymer with polypropylene, the fiber is markedly deteriorated in fiber efiiciencies such as crimpability and crimp retention or stabilty.
The most preferable composition ratio of the ternary copolymer obtained by further copolymerizing a small amount of methyl or ethyl acrylate is, based on 100% of the total composition, is 10-60% by weight of alkyl acrylates or methacrylates having alkyl group containing 16 to 20 carbon atoms, -30% by weight of vinylpyridines and 40% and/or less by weight of methyl or ethyl acrylate.
Typical examples of the alkyl acrylates or methacrylates having alkyl group containing 16 to 20 carbon atoms, which is a starting material for the preparation of the copolymer employed in the present invention, are cetyl acrylate, stearyl acrylate, eicosyl acrylate, cetyl methacrylate, stearyl methacrylate and eicosyl methacrylate. The typical examples of the vinylpyridine to be used are 2-vinylpyridine, 3-viny1pyridine, 4-vinylpyridine, 2-methyl- 5-vinylpyridine and 2-ethyl-5-vinylpyridine. In addition thereto, polymerizable vinylpyridines and vinylquinoline may also be used.
Further, in mixing polypropylene with the copolymer of the present invention, at least one member selected from the group consisting of nonionic surface active agents and/ or polyethers which are specified in the present invention is used, whereby the effects of the present invention can be further enhanced. That is, the use of the copolymer of the present invention in combination with at least one member selected from the group consisting of the specified nonionic surface active agents and/or polyethers has effective actions on the improvement in dispersibility of the copolymer in polypropylene, on the improvement in micro-fibrils formate of the copolymer in the resulting fiber and on the improvement in uniformity and fiber efficiencies of the fiber, and shows marked efiects to aid the diifusion of a dye into the fiber to improve the 'dyeability of the fiber and to improve the color depth and brightness of the dyed fiber.
The mixing of the present copolymer with the specified nonionic surface active agents and/or polyethers may be effected according to any of such procedures that the copolymer and the nonionic surface active agents and/or polyethers are mixed with polypropylene, or the nonionic surface active agents and/or polyethers are dispersed in a polymerization medium solution for the preparation of the present copolymer, the copolymer is taken out while incorporating the nonionic surface active agent and/or polyether into the copolymer, and then the copolymer is added to polypropylene. The amount of the above additives to be mixed is desirably 0.1-5 by weight based on the total polypropylene composition.
Typical examples of the specified nonionic surface active agent and polyether are polyethylene-oxide, polypropylene-oxide, polyisobutylene oxide, polytetrahydrofuran (polybutylene oxide), polyoxyethylene alkyl ethers, polyoxyethylene alkyl esters, polyoxyethylene alkyl amides, poloxyethylene alkyl amines, sorbitan derivatives, polyoxyethylene aryl ethers, polyoxyethylene aryl esters and polyoxyethylene-polyoxypropylene block copolymers. In practicing the present invention, at least one of the organo-phosphorus compounds specified in the present invention is used in combination, whereby the light fastness and the brightness of the resulting fiber, when dyed particularly to a light shade, can be greatly improved by the interaction of the copolymer employed in the present invention and the phosphite esters.
The phosphite esters specified in the present invention are compounds represented by the general formulae Ri-X R2XP R3X (I) wherein R R and R are, individually hydrogen atom, alkyl, aryl or aralkyl group; and X is oxygen or sulfur atom,
O CH: R4OP\ /C\ CH2 C1120 (11) wherein R and R are, individually, an alkyl, aryl or aralkyl group, and
wherein R R R and R are, individually, an alkyl, aryl or aralkyl group; and R and R are, individually, hydrogen atom or an alkyl group.
Concrete examples of such compounds are as follows:
These may be used either independently or in admixture of 2 or more, and the amount of such compound to be added is within the range of 05-20%, preferably ll0%, by weight based on the total polypropylene composition.
In dyeing the improved, dyeable polypropylene fiber of the present invention, it is not necessary to particularly limit scouring, dyeing and soaping processes, and acid dyes, acid mordant dyes, premetallized dyes and dlsperse dyes can be used.
Inherently, the improved polypropylene fibers of the present invention has excellent dyeability. However, in order to further improve the fastness to light of the fiber when dyed to a light shade, it is desirable to treat the fiber, either before, during or after the dyeing, with a solution or emulsified dispersion of a phosphite esters represented by any of said general Formulae I, II and III or of an alkylphenol represented by the general formula R av) The above phosphite esters or alkylphenols may be used either independently or in admixture of 2 or more.
In general, the fastness to light of a dyed fiber is dominated by the shade of the dyed fiber. In the case of a deep shade and the fastness to light is generally excellent, but in case of a light shade the fastness to light is generally poor. In accordance with the dyeing process of the present invention, the above drawback can be easily improved to a great extent.
Concretely, the dyeable fiber of the present invention may be treated with the above-mentioned phosphite esters or alkylphenols according to any of the following procedures: That is, the fiber may be treated, before dyeing, with a solution or emulsified dispersion of said compound;
- the above compound is added to a dye bath and the fiber is treated with said compound in the dye bath simultaneously with dyeing of the fiber; or the fiber is treated, after dyeing, with a solution of emulsified dispersion of said compound. The above compounds are used at a concentration of 0.1 to 50% by weight (OWF) based on the weight of the fiber.

EXAMPLE 12 100 parts by weight of a crystalline polypropylene powder having an intrinsic viscosity of 1.4 was dispersed in 500 parts by weight of hexane. To the dispersion were added 35 parts by weight of cetyl acrylate and 65 parts by weight of 2-vinylpyridine together with 1 part by weight of azobisisobutyronitrile, and the mixture was polymerized at 70 C. for 8 hours in a nitrogen atmosphere. After completion of the reaction, the reaction liquid was cooled and filtered, and the cake was washed with hexane and was then dried under reduced pressure to obtain 178 parts by weight of a white powder as product. As the result of nitrogen analysis, the nitrogen content of the product was 3.45% by weight.
For comparision, polymerization was effected in the same manner as above in the absence of the crystalline polypropylene to obtain a rubbery copolymer but no powdery polymer.
The above-mentioned product obtained according to the process of the present invention was mixed with a stabilizer and polypropylene. The mixture was adjusted to a nitrogen content of 0.35% by weight, and was then subjected to spinning and stretching in the same manner as in Example 1 to obtain a fiber. This fiber was dyed and was stretched to 5 times at 130 C. to obtain a dyeable polypropylene fiber. This fiber was scoured in the same manner as in Example 1 and was treated at 100 C. for 30 minutes at a liquor ratio of 50:1, using a treating liquid containing 3% OWF of p-tert.-octylphenol. The thus treated fiber was dyed at 100 C. for 2 hours at a liquor ratio of 50:1 in a dye bath containing 0.5% and 2.0% OWF, individually, of Fenazo Scarlet B as dye and 2 g./l. of H as assistant. The fibers after dyeing were subjected to soaping in the same manner as in Example 1 to obtain dyed fibers. The fastness to light of the dyed fibers were as shown in Table 12.

The mixture was pelletized at 220 C., was subjected to meltspinning at 260 C. and was stretched to 6 times at C. to obtain a dyeable fiber of the present invention. The thus obtained fiber had such mechanical property as a denier of 3.0, a strength of 5.8 g./d. and an elongation of 32%. This fiber was subjected to scouring, dyeing and soaping under the same conditions as in Example 1. The dyed fiber was excellent in both color depth and brightness, showing a degree of dye exhaustion of 92%, a fastness to light of the 5th grade and a fastness to wash of the 5th grade.
EXAMPLE 19 excellent dyeability as set forth in Table 15.
