[Problem] It is known that in wound healing, when pH in blood decreases, oxygen is released from hemoglobin, blood oxygen concentration rises, division of regenerated epithelial cells is promoted, and healing is promoted. Wound therapeutic agents such as creams or ointments are weakly acidic, and therefore, the described healing promoting effect can be expected; however, in being applied by the fingers, the wound therapeutic agent will need to be wiped off, and other adverse handling-related attributes are encountered, there being a risk presented of further damage to the wound when the agent is applied.

ION-EXCHANGE FIBER, AND ION-EXCHANGE FILTER CONTAINING SAME
Strongly acidic cation-exchange resins, chelate resins, weakly acidic cation-exchange resins, etc. have conventionally been used for removing metal ions present in aqueous solutions. However, there are problems in that strongly acidic cation-exchange resins require large amounts of acids for regeneration and have low selectivity for adsorbed ions, chelate resins have good selectivity but low ion-exchange capacity, and weakly acidic cation-exchange resins have relatively good selectivity but suffer from high breakthrough of heavy metal ions under high flow rates. The purpose of the present invention is to provide an ion exchanger having good selectivity for heavy metals, high ion-exchange capacity, and suppressed breakthrough.

FILTER AID, AND FILTER AND HYGIENE PRODUCT CONTAINING FILTER AID
[Problem] Conventionally known filter aids include those made of a cellulose powder, those in which diatomaceous earth is used, and adsorbents in which an amino group is utilized. However, the filter aids were not necessarily satisfactory; for example, there was a lack of improvement in the filtrate clarity when treating liquids having a high turbidity, and there were concerns regarding safety and the disposal method after use. The present invention was developed in view of the current state of the prior art, and the purpose thereof is to provide a filter aid having a superior performance compared to conventional materials, and a filter containing the filter aid. [Solution] A filter aid comprising an acrylonitrile polymer containing at least 70 wt% of acrylonitrile units and 0.05-2.0 mmol/g of amino groups or ammonium groups, and having a specific surface area of 0.1-400 m2/g.
[Problem] Adsorption heat cycle performance is determined by how quickly a large amount of moisture absorption is obtained, in other words, by the amount of moisture absorption and the rate of moisture absorption. However, conventional hygroscopic materials cannot achieve sufficiently both an excellent amount of moisture absorption and an excellent rate of moisture absorption, thereby limiting adsorption heat cycle performance. Due to said limitation, device miniaturization is difficult, leading to a delay in supply. In particular, a vehicle-mounted adsorption refrigeration cycle having a limited installation capacity has a significant problem of insufficient performance of hygroscopic materials, so that commercialization thereof is hindered. The objective of the present invention is to provide a hygroscopic material that achieves both high hygroscopicity and a high rate of moisture absorption. [Solution] This high-speed moisture-absorbing/desorbing polymer is an organic polymer characterized by containing 2.0-8.0 mmol/g of a carboxyl group in which a counter cation is an organic onium ion, and having a crosslinked structure, wherein all the alkyl groups contained in the organic onium ion have 1-4 carbon atoms.

[Problem] In manufacturing porous ceramic filters, the combustion heat of a pore-forming agent brings about a problem of cracking. In order to reduce the heat generation amount, therefore, use of hollow particles and calcination in a low-oxygen atmosphere have been proposed. However, hollow particles are fragile, while equipment should be repaired to provide a low-oxygen atmosphere. The purpose of the present invention is to provide a pore-forming material which comprises solid particles but yet can suppress heat generation even in a conventional calcination step. [Solution] A pore-forming material for manufacturing a porous ceramic filter, which comprises solid particles containing a polymer, said polymer containing, as copolymerization components, 80 mass% or more of a monomer having a spontaneous ignition temperature of 350oC or higher and having one (meth)acryloyl group and 10 mass% or less of a monomer having two or more (meth)acryloyl groups, and also containing 0.5-5 mass% of polyvinyl alcohol on the surface thereof.

[Problem] Regarding a pile fabric using synthetic fibers, attempts have been made to taper the distal ends of the fibers in order to approach the feel of real fur. However, in the prior art, in addition to a pile processing step, a step and equipment for tapering were also necessary, and sufficient tapering has not been achieved, and thus satisfactory quality has not been obtained.

[Problem] Beaten acrylonitrile-based fibers having a carboxyl group, have a high water-swellable property, and therefore are considered to have an advantage in terms of powder catching ability. However, this property also leads to an aspect of easily being shrunk when heated or dried, disadvantageously resulting in poor shape stability during processing. The purpose of the present invention is to provide carboxyl group-containing beaten acrylonitrile-based fibers having excellent shape stability. [Solution] Beaten acrylonitrile-based fibers according to the present invention comprise a polymer having a carboxyl group content of 0.2-4.0 mmol/g but substantially not having a crosslinked structure formed by a covalent bond, and is characterized in that the shrinkage rate thereof is 25% or less when formed in the shape of paper having a basis weight of 50 g/m2.

WATER-ABSORBING FIBER PRECURSOR, WATER-ABSORBING NONWOVEN FABRIC PRECURSOR AND WATER-ABSORBING NONWOVEN FABRIC, FACE MASK CONTAINING THESE AND SKIN LOTION-FILLED FACE MASK, AND MANUFACTURING METHOD OF THERE
[Problem] In a face mask soaked with skin lotion, etc., a nonwoven fabric including a water-absorbing fiber is used in order to improve liquid retainability and wearing comfort. Such a nonwoven fabric is manufactured mainly by thermal bonding, but there is few interlacing of fibers and fluff tends to remain on the skin after being worn. Although spun lacing is effective for fluff reduction, there is difficulty applying it to water-absorbing fibers that swell by absorbing water. The present invention provides a spun-laced water-absorbing nonwoven fabric.

POLYMER PARTICLES AND PRODUCTION METHOD THEREFOR, AND COATING LIQUID COMPOSITION, SHEET, RESIN MOLDED ARTICLE, FIBER, AND VISCOSITY-ADJUSTING AGENT HAVING SAID PARTICLES
[Problem] When a carboxyl group-containing water-soluble monomer and a cross-linkable monomer undergo copolymerization in water, gelation occurs, and therefore, it is difficult to stably form particles. Under these circumstances, known is a method of cross-linking, by using hydrazine, particles copolymerized with a hydrophobic monomer having a nitrile group or an ester bond, and forming a carboxyl group by hydrolysis. However, the method includes a large number of production steps, and monomers that can be used in the method are limited. The purpose of the present invention is to provide carboxyl group-containing cross-linked polymer particles which can be simply obtained in an aqueous solvent, without a hydrolysis step, without the occurrence of gelation, and using few steps. [Solution] The polymer particles according to the present invention have a cross-linked structure with an acid type and/or a salt-type carboxyl group, and are characterized by being obtained by polymerization of a mixture containing a carboxyl group-containing vinyl water-soluble monomer and a compound having a polyoxyalkylene chain.

This moisture absorbent acrylonitrile-based fiber requires no step of introducing a crosslinked structure and has sufficient fiber properties, which enables continuous production thereof. The moisture absorbent acrylonitrile-based fiber has high water absorbent properties and, moreover, shows no increase in redness during use. In addition, shrink properties, easy-decrimping properties, bulkiness and water repellency can be easily imparted to the fiber.

HYGROSCOPIC GRANULATED WOOL AND BATTING CONTAINING SAME GRANULATED WOOL
Hygroscopic fibers have low loft or resilience, which makes development thereof into a batting problematic. Although several techniques are known for enhancing loft, only initial loft is secured, and there is a significant tendency for loft to decrease due to moisture, repeated use, passage of time, and other factors. The present invention was developed in view of the current state of the prior art, and the purpose thereof is to provide a hygroscopic granulated wool and a batting containing the granulated wool, whereby hygroscopic properties and continuous loft are obtained at the same time.

Acrylic fibers have excellent heat-retaining properties, and therefore have been used frequently in clothing items such as a sweater and an underwear. Concretely, when shrinkable acrylic fibers are blended to increase void spaces between fibers, although lightweight properties/bulkiness can be achieved, there is still a disadvantage that pilling is likely to occur. In this regard, there are several proposals, but both of a satisfactory level of lightweight properties/bulkiness and practically effective pilling resistance are not attained yet. The present invention addresses the problem of providing an acrylic spun yarn and a fabric, each of which has both lightweight properties/bulkiness and pilling resistance. A spun yarn comprising acrylonitrile-based fibers A and acrylonitrile-based fibers B, said spun yarn being characterized in that the acrylonitrile-based fibers A have a single fiber fineness of 0.3 to 1.7 dtex after a boiled water treatment and a single fiber elongation of 50% or more, and the acrylonitrile-based fibers B have a single fiber fineness of 0.3 to 2.2 dtex after a boiled water treatment and a single fiber elongation of 30% or less; and a fabric containing the spun yarn.
[Problem] In prior art, in order to give excellent electrolyte-holding abilities, acid resistance, oxidation resistance, and the like, to a separator, various studies have been carried out, as in subjecting a fiber to hydrophilization, or combining different types of fibers. However, these methods have the problem of involving dangerous processes and high costs, and the problem of not yielding separators that are satisfactory in terms of battery performance, due to a rise in the separator resistance value. The objective of the present invention is to provide an acrylonitrillic fiber for a separator, a separator containing the fiber, and a lead-acid battery containing the separator requiring no dangerous processes during production, having an excellent electrolyte-holding capacity, and capable of suppressing a rise in the separator resistance value.

NONWOVEN FABRIC STRUCTURE AND PADDING AND CUSHION MATERIAL CONTAINING SAID STRUCTURE
[Problem] When using moisture-absorbing and -releasing fibers in padding for clothing or bedding, improvement of loft is an important problem. With improvement of loft by modification or crimping, reduction of loft due to repeated use or over time has not been improved.

Attempts have been made in the prior art to obtain wet sheets, modified cross-section hollow fibers, and the like that are capable of holding a large amount of a functional component, but it was difficult to use the results as a fiber product, the sustained release properties of the results decreased with repeated use, and it was therefore impossible to obtain satisfactory performance. The present invention was conceived in view of the current state of the related prior art. The purpose of the present invention is to provide: fibers that are capable of the sustained release of a functional component, that make it possible for various functional components to be absorbed to the central part of said fibers and released in a sustained manner as a result of exhibiting a suitable moisture swell rate and having a suitable saturated moisture absorption rate, and that can be suitably used as a fiber product such as underwear as a result of being capable of absorbing and releasing a functional component in a sustained manner even when used repeatedly; a fiber structure and underwear containing the fibers; and a regeneration processing method therefor.

[Problem] Conventionally, studies have been undertaken into using fibers in which a monomer having a hydrophilic group is graft copolymerized on the surface of a thermoplastic synthetic resin, such fibers serving as a short fiber for reinforcement to be included in the active material layer of electrodes, in order to increase the utilization efficiency of the active material in the electrode and improve the battery capacity. However, in these methods, there was a problem in that, with the passage of time, the hydrophilic polymer layer tended to be preferentially decomposed by contact with acid and thus the battery capacity decreased. The purpose of the present invention is to provide an acrylonitrile-based fiber for electrodes that has excellent acid resistance, such that there are few decomposition issues, even with long-term use, and to provide an electrode containing the fiber and a lead-acid battery having the electrode.

[Problem] Many of the conventional deodorants have a problem of not exhibiting sufficient deodorization effect on some kinds of odors, particularly, not exhibiting satisfactory deodorization effect on complex odors such as a sweat odor or a body odor associated with aging, though the conventional deodorants exhibit excellent deodorization effect on specific kinds of odors. When added to a resin or the like, the conventional deodorants also cause a problem of deteriorating the wear resistance or other performance of the resin. In order to solve such problems of the prior art, the present invention provides moisture-absorbing deodorizing microparticles which when added to a resin, do not significantly deteriorate the wear resistance of the resin and which can impart not only high deodorization performance against basic and acidic odors but also moisture-absorption performance to the resin.

This invention provides a desiccant air conditioning system that, even when the temperature of the air to be treated is low, can remove moisture in a continuous and efficient manner. The desiccant air conditioning system comprises a desiccant rotor and a refrigerating cycle comprising a compressor, an evaporator, and a condenser. The desiccant rotor is a honeycomb-shaped desiccant rotor with a desiccant supported thereon, which can adsorb moisture in the air and can desorb the moisture into the air, and is partitioned into an adsorption zone for adsorbing moisture and a desorbing zone for desorbing the moisture. Air which flows in the adsorbing zone substantially counters air which flow in the desorbing zone. The desiccant air conditioning system is characterized by having such a construction that the treatment air introduced into the system flows in the order of the desorbing zone in the desiccant rotor, the evaporator in the refrigerating cycle, the adsorbing zone in the desiccant rotor, and the condenser in the refrigerating cycle.
