下記組成の樹脂組成物処理液を調製した。
The present invention relates to a method for post-treatment of wet resin-coated fibrous materials. More specifically, the present invention relates to a post-treatment method for improving the moisture permeability and hand of a wet resin-coated fibrous material and increasing the adhesion between the resin coating and the fibrous material substrate. Conventionally, various proposals have been made regarding methods for producing resin-coated fiber materials having good moisture permeability. These conventional methods are based on the principle of applying or impregnating a fiber material substrate with a resin-containing treatment liquid and wet-solidifying it in a coagulating liquid to make the solidified resin coating layer microporous. It is. In this conventional method, by appropriately selecting conditions such as the concentration of the resin-containing treatment liquid, the type of solvent, the type and amount of surfactant used, and the composition and temperature of the coagulating liquid, fine particles of the resin coating layer can be formed. The porous structure can be adjusted. However, in the conventional method, the microporous structure of the resin coating layer formed in the coagulation liquid is unstable, and it is difficult to maintain this structure until after the final process. There are problems in that there are variations in quality and productivity is low. Generally, post-treatment is necessary to stabilize the resin coating layer formed in the coagulation liquid. This post-treatment is carried out by drying the resin-coated fiber material at a temperature within a range where the resin coating layer does not deteriorate or the solvent does not change, generally at a temperature of 120 to 150°C.
However, dry heat treatment at a relatively low temperature as described above requires heating for a considerable period of time, for example 3 to 10 minutes, to complete stabilization. For example, when using a tenter with a heating chamber of 20 m in length for the above-mentioned dry heat treatment, the operating speed of the tenter must be reduced to 5 m/min or less in order to perform the dry heat treatment for at least 4 minutes. . Such low-speed operation reduces product productivity, increases costs, and is extremely disadvantageous in practical terms. It is also already known that the strength of the resin coating layer can be improved by adding a blocked isocyanate to the resin composition and crosslinking it. When using such a blocked isocyanate, in order for it to dissociate and crosslink,
A temperature of 150°C or more and a heating time of 3 minutes or more are required. Such a long dry heat treatment significantly reduces productivity. However, if the dry heat temperature is increased to shorten the processing temperature,
This results in drawbacks such as fusion of the resin coating layer and reduced strength.
Therefore, there is a problem that the moisture permeability and durability of the product are reduced. The purpose of the present invention is to solve the problems of the conventional methods as described above, and to provide a post-processing method capable of producing wet resin-coated fiber materials having good moisture permeability and durability in a short period of time and at high speed. The goal is to provide the following. In the method of the present invention, a fiber material substrate is coated or impregnated with a treatment liquid containing a resin composition, then immersed in a coagulation liquid to form a resin coating layer, and after drying, the obtained This method is characterized by subjecting the resin-coated fiber material to a wet heat treatment in saturated or supersaturated steam. In the method of the present invention, there are no particular limitations on the type, shape, etc. of the fiber material used as the substrate, as long as it is not altered or solvated by the post-treatment step in the method of the present invention. .
For example, cellulose fibers such as cotton, rayon, and kyupura, polyamide fibers such as nylon 6 and nylon 66, polyester fibers such as polyethylene terephthalate fibers, acrylic fibers such as polyacrylonitrile fibers, and water-insoluble polyvinyl fibers. Woven fabrics, knitted fabrics, nonwoven fabrics, nets, and composites thereof, which are made of at least one type of fiber selected from alcohol fibers, cellulose acetate fibers, etc., can be used. The resin composition used in the method of the present invention is not particularly limited in type as long as it can form a microporous resin coating layer by wet coagulation. in general,
The main components of the resin composition are polyurethane polymers,
selected from polyacrylic acid ester polymers, and blends of two or more thereof. The polyurethane-based polymer can be selected from known ether-type polyurethanes and ester-type polyurethanes, and the acrylic compound-based polymers include acrylic compound-based polymers such as acrylonitrile, methacrylic acid, methacrylic ester, and acrylic acid. , one or more kinds of polymers such as methacrylic acid esters, copolymers of acrylic compounds and other ethylenically unsaturated monomers, and the like. The resin composition may contain 1 to 8% by weight of a crosslinking agent, such as a polyimine resin, a butylated melamine resin, an epoxy resin, and/or a blocked isocyanate, and, if necessary, a coloring agent. , stabilizers and cell regulators (surfactants)
It may also include. The resin composition treatment solution is a resin composition treatment solution in which a desired resin composition is mixed with a desired water-miscible organic solvent such as N,N'-dimethylformamide, N,N'-diethylformamide (DEF), dimethyl sulfoxide (DMSO),
It is prepared by dissolving it in N,N'-dimethylacetamide (DMAC), tetramethylurea (TMU), tetrahydrofuran (THF), dioxane (DOX), metacresol, or the like. Although the concentration of the main resin component in this treatment liquid can be set arbitrarily, it is generally preferably 5 to 25% by weight. The resin composition treatment solution is applied to or impregnated onto a fibrous material substrate using conventional and inexpensive methods and equipment. The amount of the resin composition treatment liquid to be applied or impregnated can be set arbitrarily, but generally, the dry solid content is 5% by weight based on the weight of the fiber material base.
~30% is preferred. The fiber material coated or impregnated with the resin composition treatment liquid is introduced into a coagulation liquid, where the main resin component is coagulated to form a resin coating layer. The composition of the coagulating liquid is appropriately determined depending on the composition of the processing liquid, but generally water or a mixture of water and an organic solvent is used. The temperature of the coagulating liquid is generally 20 to 50°C. The resin-coated fibrous material obtained by the above process is washed to remove the solvent and then dried, generally at a temperature of 100-120°C. The dried resin-coated fiber material is subjected to an appropriate finishing treatment, for example, water repellent treatment, if desired, and then subjected to the post-treatment of the present invention. In the post-treatment of the present invention, the resin-coated fibrous material is introduced into saturated or supersaturated steam and subjected to a moist heat treatment. At this time,
The heat-and-moisture treatment is preferably performed at a temperature of 100 to 150°C for 30 seconds to 3 minutes, and the heat-and-moisture treatment is preferably performed in an atmosphere having a humidity of 70% or more. If the moist heat temperature is lower than 100°C, the time required to complete stabilization of the resin coating layer will be longer, and depending on the type and composition of the resin used, there is a risk of hydrolysis occurring. Furthermore, if the moist heat temperature is higher than 150°C, the texture of the resin coating layer may become hard or deteriorate. If the moist heat treatment is performed at a humidity lower than 70%, it will take a long time to complete the stabilization of the resin coating layer, and the stabilization of the resin coating layer will not be completed within a practical moist heat treatment time. Generally, in the post-treatment of the present invention, it is more preferable that the heat-and-moisture treatment is carried out at a temperature of 110 to 120°C in an atmosphere with a humidity of 90% or more, and the required heat-and-moisture time at this time is 1 to 2. It is a minute. Curing of polymers is usually carried out by dry heat, and there is no example of a stabilization treatment of a resin coating layer by moist heat, such as the method of the present invention, other than the addition of rubber. Conventionally, it has been believed that the presence of water in the heating medium inhibits the volatilization of the solvent from the resin coating layer and the crosslinking reaction of the isocyanate. However, the inventors of the present application have found that even in wet heat treatment, when saturated or supersaturated steam is used, the above-mentioned solvent does not volatilize or the crosslinking reaction of isocyanate is inhibited, and on the contrary, the resin can be processed in a short time. They discovered that the stabilization of the coating layer can be completed. Although the reason for the above-mentioned effect in the post-treatment of the present invention is not fully clarified, it is presumed that the necessary thermal energy is effectively transmitted to the object to be treated in the moist heat treatment using saturated or superheated steam. Furthermore, the post-treatment method of the present invention does not adversely affect the moisture permeability or texture of the resin coating layer, and can improve the adhesive strength between the fiber material substrate and the resin coating layer. The method of the present invention will be further explained below with reference to the following examples. Example 1 A resin composition treatment solution having the following composition was prepared.
