More specifically, the present invention relates to the use of acrylic fibers with excellent heat-resistant color fastness as a surface material for electric pets and electric pets using the same. (Prior Art) Conventionally, acrylic fibers have been widely used for carpets, especially household carpets that are often walked on barefoot, due to their vivid color development and soft, warm composition. on the other hand,
Electric force-PET with built-in heater has become popular in recent years, but conventional acrylic fibers have insufficient heat-resistant color fastness and have high elongation at high temperatures. When used as a surface material, it has the disadvantage of discoloration or cracking, and in reality it is
Not used as a pet surface material. As is well known, acrylic fibers have excellent color development, texture, and volume. If these shortcomings can be overcome, acrylic fibers will be as good as the polyester, polyamide, wool, etc. currently used as a surface material for electric pets. It is easy to guess what will happen. However, no acrylic fiber has been developed or known that eliminates the above-mentioned drawbacks. (Problems to be Solved by the Invention) An object of the present invention is to provide acrylic fibers as a material for surface materials for electric pets. Another object of the present invention is to provide a surface material for electric pets containing acrylic fibers having excellent heat-resistant color fastness and set resistance. Still another object of the present invention is to provide an electric power pet equipped with the above-mentioned surface material of the present invention. Further objects and advantages of the present invention will become apparent from the description below. (Means and effects for solving the problems) According to the present invention, the above objects and advantages of the present invention are as follows: (A), (a) Polymerization represented by the following formula (1) % formula % unit and the following formula (2) % formula % where M is a hydrogen atom or a -equivalent cation, consisting essentially of a polymerized unit represented by (b) the above polymerized unit (1) and the polymerized unit (2) (c) consists of an acrylonitrile-based copolymer in which the polymerized unit (2) accounts for 0.4 to 1.5 mol% relative to the total of (c) the degree of polymerization is in the range of 600 to 1.500; ) In the relationship between temperature and elongation rate measured under elevated temperature, 260℃
This is achieved by an electro-pet surface material characterized in that it contains acrylic fibers, with an elongation rate of 10% or less. As mentioned above, the acrylic fiber used in the surface material of the present invention is a novel acrylic fiber characterized by the requirement (A) for specifying the polymer that forms it and the requirement CB for specifying its elongation rate at high temperatures. It is a fiber. Regarding the key point (A), the polymer has polymerized units of the above formula (1) derived from acrylonitrile and 2 to acrylamide-
It consists essentially of polymerized units of the above formula (2) derived from 2-methyl-propanesulfonic acid (hereinafter abbreviated as AMPS) or a salt thereof. The ratio of polymerized units (1) and polymerized units (2) is 0.4 to 1.5 mol% of polymerized units (2) (99.6 to 1.5 mol% of polymerized units (1)) based on the total of both polymerized units. 98.5 mol%). The polymerized unit (2) is preferably 0.6 to 2 mol% (polymerized unit (1) is 9
9.4 to 98.2 mol%). If the proportion of the polymerized unit (2) is less than 0.4 mol %, gelation tends to occur during the polymerization process, and deep color dyeing becomes difficult due to insufficient dyeing seat. Also, if it exceeds 1.5 mol%,
Heat resistance characteristics, which will be described later, deteriorate. Furthermore, regarding requirement (A), the above polymer has a degree of polymerization of 600.
~1.500. The preferred degree of polymerization is 800~
It is 1,100. If it is less than 600, the strength as a normal acrylic fiber cannot be obtained, and if it exceeds 1.500, gelation is likely to occur during the polymerization process, and in order to carry out normal wet spinning,
Viscosity is too high. As specified in requirement (A), the acrylic fiber used in the surface material of the present invention has a polymerization unit (1) and a polymerization unit (2) based on the sum of these units.
2) in a proportion of 0.4 to 1.5 mol%. According to the research of the present inventor, polymerized unit (1) and polymerized unit (
It has been found that the above objects and advantages of the present invention can be maintained even if a small amount of other polymerized unit (3) is further contained under the condition that the above ratio of 2) is maintained. That is, the acrylonitrile copolymer containing such other polymerized units (3) meets the following requirement (A) instead of requirement (A).
): (A) (a) Polymerized unit of the above formula (1), the above formula (2)
) and the polymerized unit represented by the polymerized unit (3) which is different from the polymerized unit of the above formula (2) derived from a monomer copolymerizable with acrylonitrile, (b1) the above polymerized unit The polymerized unit (2) accounts for 0.4 to 1.5 mol% of the total of (1) and the polymerized unit (2), and the polymerized unit (3) accounts for 5% by weight based on the polymerized unit (1). % or less, - and - (C) degree of polymerization is 6
In the range of 00 to 1.500, satisfies the following. Regarding requirement (A'), polymerized unit (1) and polymerized unit (2)
The ratio of polymerized units (2
) is 0.4 to 1.5 mol% (polymerized unit (1
) is 99.6 to 98.5 mol %), the process is the same as requirement (A). Regarding the requirement (A'), in addition to the polymerized units (1) and (2), there is another polymerized unit (3) that is compatible with the polymerized unit (2) derived from a monomer copolymerizable with acrylonitrile, Present in up to 5% by weight, based on polymerized units (1). Polymerized units (3) are preferably present in an amount of 3% by weight or less based on the same criteria. As the polymerized unit (3), preferably, for example, the following formula (
3) Here, R is a hydrogen atom or a methyl group, and Y is a group represented by the formula -〇〇X (where X is a hydrogen atom, a sodium atom, or a methyl group) -, -0COCH3
, -CONH,, -C,H,, -CHzSOsNa, and -C@HaSO3N &, can be mentioned. The acrylonitrile polymer used in the present invention, a monomer that provides the polymerized unit (1) by cleavage of a double bond, a monomer that provides the polymerized unit (2), and optionally the polymerized unit (3). It can be produced by polymerizing monomers giving the following in predetermined amounts. The acrylonitrile polymer may be polymerized by any known method such as aqueous polymerization, emulsion polymerization, or solution polymerization. Furthermore, regarding requirement (B), any of the above acrylic fibers used in the present invention has an elongation rate at 260° C. of lθ% or less in the relationship between temperature and elongation rate measured under elevated temperature. The preferable elongation rate is 6% or less. The acrylic material used in the surface material of the present invention has excellent heat resistance and less sagging under high environmental conditions than conventional acrylic materials. Furthermore, the acrylic fibers used in the surface material of the present invention generally have favorable properties in terms of heat-resistant color fastness, and the heat-resistant color fastness (dry heat 120°C x 48 hours) is preferably at least grade 3, more preferably indicates at least grade 3.5. The acrylic fiber used in the surface material of the present invention is further unique in that it exhibits such excellent heat resistance compared to conventional acrylic fibers. The acrylic fiber used in the surface material of the present invention preferably has the following properties. The dry relaxation contraction rate at 210°C is preferably 3% or less, more preferably 1
% or less. Young's modulus is preferably 400 to 700
kjf/rn is, more preferably 500-6
00 kllfl■■2. The tensile strength is preferably 2 to 51/d, more preferably 3 to 42/d. The tensile elongation is preferably 35% or more, more preferably 35 to 60%. The acrylic iiiui used in the surface material of the present invention can be selected from the acrylonitrile polymers specified in (A) or (A') above, such as (1) the acrylonitrile polymer specified in (A) or (A') above. A copolymer spinning dope is extruded through an orifice of a spinneret to produce a trickle of the spinning dope, (2) the trickle is solidified and stretched 5 to 10 times to produce a drawn yarn, and (3) the drawn yarn is drawn. It can be produced by a method characterized by heating the yarn to shrink it by 3 to 25%, and (4) subjecting the obtained shrink yarn to a drying process. It goes without saying that the spinning dope used in step (1) above can be prepared by dissolving the acrylonitrile polymer in a solvent, but it can also be a polymerization solution containing the polymer obtained as a result of polymerization. In the latter case, it is desirable to employ a polymerization reaction system that can be used as a spinning stock solution for wet spinning by simply recovering unreacted monomers from the polymerization solution. The spinning method in step (1) above may be any known method such as wet spinning, dry-wet spinning, dry spinning, or semi-melt spinning. Wet spinning or dry spinning is particularly preferred. These spinning methods are known per se, and for example, wet spinning is described in Japanese Patent Publication No. 167.410, Japanese Patent Application Laid-Open No. 167.411, Japanese Patent Application Laid-Open No. 1972-210,
The method disclosed in Japanese Patent Application Laid-open No. 011, Japanese Patent Application Laid-open No. 58-132107, is employed. Regarding the dry method, for example, JP-A-49-
Publication No. 1.665 or Special Publication No. 59--21.711
As for the method described in the above publication and the dry-wet method, the method described in Japanese Patent Application Laid-open No. 51-92316, etc. are employed. No matter which spinning method is used, the spinning dope is processed in step (1).
, which is extruded from the spinneret to form a trickle of spinning dope. In wet spinning, the trickle is forced into the coagulating liquid,
In dry spinning, the rivulet is extruded into a hot gas atmosphere, and in the wet-dry method, the rivulet is extruded into a gas atmosphere and then introduced into a coagulating liquid. Next, in step (2), the trickle is stretched 5 to 10 times while undergoing solidification as described above. Stretching can be carried out in one stage or in multiple stages. The stretching ratio of each stage in multi-stage stretching is appropriately selected within a range where the total ratio is 5 to 10 times. The preferred stretching ratio is 6 to 8 times. If the stretching ratio is less than 5 times, the tensile strength of the fibers will be insufficient, and if it exceeds 10 times, single fiber breakage will easily occur and fibrillation will occur. The drawn yarn obtained in step (2) is then subjected to a washing step (in the case of wet and wet-dry spinning) or oiled, if necessary, and then guided to the heating step of step (3). In step (3), the drawn yarn is heated to shrink by 3 to 25%. If this shrinkage is less than 3%, the tensile elongation of the fiber will be insufficient;
If it exceeds 5%, high temperature drying becomes necessary, which is not economical. When the spinning in step (1) is carried out by wet spinning, this shrinkage can be carried out using hot water or warm heat before the so-called pre-drying step before subjecting the drawn yarn to the crimper. Alternatively, it can be carried out in a pre-drying step. The resulting shrink yarn is then dried in step (4). If the shrinkage is carried out in or immediately before the so-called pre-drying step as described above, this step (4) corresponds to the so-called post-drying which is carried out after crimping if necessary. do. The acrylic fiber used in the surface material of the present invention obtained by m1< is cut into a predetermined length using a cutter. The electric power pet surface material of the present invention is distinctive in that it contains the above-mentioned novel acrylic fibers with excellent performance. Such acrylic fibers are preferably used in the facing material in an amount by weight of at least IO, more preferably at least 30% by weight. A surface material containing at least 10% by weight of acrylic fibers is advantageous because it can take advantage of the vivid color development and warm texture of the acrylic fibers. Fibers that can be mixed with acrylic fibers include hoods, such as wool, polyester, and nylon! ! I! Examples include fibers with a good diameter. According to the present invention, there is also provided an electrified carpet using the above surface material of the present invention on the outermost or outer surface. The structure of the surface material may be any known structure, such as a non-woven fabric made by needle punching or the like, a woven fabric such as a pile fabric made by tufting, or a knitted fabric in some cases. The electric force pet of the present invention may be in the form of a heater, or it may be made up of a separate heater body and force bar carpet.
It may also be in the shape of a square. (Example) The present invention will now be described in detail in two examples. Note that unless otherwise specified, parts and percentages are by weight.
