- a conventional fiber such as polyester or a crosslinked polyacrylate fiber such as Na salt type.
- Such an effect is brought about not only by the bulkiness of the polyester fiber but also by the high single fiber elastic modulus and moisture absorption exothermic property of the Mg salt type or Ca salt type polyacrylate fiber.
- the batting of the present invention can be suitably used for batting and autumn / winter outdoor clothing batting because a large amount of air taken in due to its bulkiness can be changed to warm air with low humidity due to moisture absorption heat generation. be able to.

- general-purpose fibers fibers such as acrylic and cotton
- polyester fibers can be used, but it is preferable to select those having a single fiber elastic modulus of 10 cN / dtex or more.
- fibers having a low single fiber elastic modulus are used, the bulkiness of the entire batting becomes insufficient, and the heat retention may be lowered.
- the cross-linked polyacrylate fiber used in the present invention needs to be a divalent metal Mg salt type or Ca salt type.
- a monovalent metal salt type such as a Na salt type is not preferable because the bulkiness is insufficient and the heat retention is not maintained.
- other divalent metal salt types such as a Zn salt type are not preferable because they are inferior in hygroscopic heat generation and a comfortable environment cannot be obtained.
- the Mg salt type or the Ca salt type has a high moisture absorption exothermic property and also has a moderately high bulkiness, so that the high bulkiness effect of the polyester fiber can be fully enjoyed.
- the reason why the Mg salt type or the Ca salt type is excellent in bulkiness is that, in the case of these divalent metals, the elastic modulus is improved by forming an ionic cross-linked structure with a carboxyl group between the polymers. It is guessed.

- the batting of the present invention contains Mg salt type and / or Ca salt type cross-linked polyacrylate fiber in a specific amount or more, so 50 to 100 cm 3 / g.
- a range of specific volumes can be achieved.
- Such high bulkiness is brought about by the high single fiber elastic modulus of the Mg salt type or Ca salt type cross-linked polyacrylate fiber or polyester fiber.
- the specific volume is less than 50 cm 3 / g, heat retention may be insufficient because sufficient air is not taken in. If the specific volume is larger than 100 cm 3 / g, the shape may be easily lost by applying a small amount of force, and the shape retention may be insufficient.

This is brought about by the high hygroscopicity and bulkiness of the Mg salt-type or Ca salt-type crosslinked polyacrylate fiber and the high bulkiness of the polyester fiber.
- the temperature and humidity in the bed are in this range, a comfortable warmth with a low humidity can be realized when human skin comes into contact.
- the method for producing the batting of the present invention is not particularly limited, and a conventionally known method for producing batting can be applied.

- the batting of the present invention described above has a comfort of low-humidity unprecedented warmth in order to combine hygroscopicity and bulkiness at a high level. For this reason, bedding (comforters, mattresses, pillows, etc.) or outerwear for autumn and winter using the batting of the present invention absorbs moisture released from the human body and generates heat, thereby suppressing humidity and warming. It is possible to feel the warmth continuously by the heat retaining property due to the bulkiness.

試料約2.5gを熱風乾燥機で105℃、16時間乾燥して重量を測定する(W1[g])。次に該試料を20℃×65%RHに調整した恒温恒湿器に24時間入れておく。このようにして吸湿させた試料の重量を測定する(W2[g])。これらの測定結果から、吸湿率を次式によって算出した。
吸湿率[%]={(W2-W1)/W1}×100
試料50gを軽く開繊してから、カード機で開繊し、積層する。試験片は10cm×10cmの大きさになるように6個切り出し、バットに入れて恒温恒湿機内に24hr以上放置する。恒温恒湿機から取出し、質量が10.0g~10.5gになるように積み重ね、作られた試験片を正確に秤量する。試験片に10cm×10cmのアクリル板を載せ、おもり500gを30秒間載せ、次にこのおもりを除き、30秒間放置する。この操作を3回繰り返し、おもり500gを除いて30秒間放置した後、四すみの高さを測定して平均値を求め、次式により比容積を算出する。
比容積(cm3/g)=10×10×試料の四すみの高さの平均値(mm)/10/試験片の質量(g)
