[Industrial applications]

 The present invention is particularly well-suited for bedding because it has particularly good heat retention, humidity control, and breathability for both comforters and mattresses made of wool cotton that have been used in the past. There is a drawback that it becomes thinner and harder and it becomes felt, and it is a healthy, economical, and practical elastic cotton wool for bedding that keeps the goodness of wool for a long time by removing it and maintaining strong elasticity for a long time. It is what you get.

[0002]

[Prior art]

 Wool cotton, which is conventionally used for comforters and mattresses, is made by expanding the crimpability of wool simply by heat treatment to form a cotton spreader with a cotton maker. It is made thin and hard and felted by applying pressure.

[0003]

[Problems to be solved by the device]

 As mentioned in the prior art, since wool cotton has been widely used for bedding in 1952, there is no major processing technology, and recently heat treatment such as dry drying by steam heat is finally applied. It is a well-known fact in the industry that the technology of strengthening the crimping of wool is being carried out, and the fact that 30% of the thickness of the initial use during a long-term use is a cabbage.

[0004]

[Means for solving the problem]

In order to solve the above-mentioned drawbacks and to achieve the object, the present invention forms wool (1) with a cotton-making machine into a cotton-like shape whose wool crimp crimping property is strengthened by heat-treating, and acrylates the web. A proper amount of foaming agent (eg, thermally expandable microcapsules containing low boiling point hydrocarbon with a shell wall made of pinylidene chloride copolymer) mixed in resin solution, and a thinly melted solution is sprayed and sprayed in a mist with a blower. And then, the hardness is 0.1-0.05 by the hardness tester (SRIS-0101 type GS-701) which is heat-treated by the well-known technique and laminated softly and lightly by stacking 100 ℃ -150 ℃, and the inner and outer dimensions are 1500mm × length 2000 m m, thickness 80 mm-100 mm, eyes 1.6 kg-2 kg, density ^{0.01g / c m 3 -0.0125g / cm} 3, 100% of the results similar test out elastic recovery JISL-2001 standard Nokake To obtain a resilient wool cotton for Dan. (See FIG. 1-reference numeral 2) Next, a foaming agent (eg, the above-mentioned thermal expansion property) is applied to a liquid in which polyurethane resin is thinly dissolved in a wool-like (1) web with a solvent (eg, methyl chloride). Microcapsules, etc. are sprayed and laminated in a mist with a mixed blower (3) and heat-treated and foamed by a well-known technique at 100 ° C-150 ° C. Width 1000 mm x length 2000 mm, thickness 80 mm, weight 5.5 kg , A density of 0.034 g / cm ³ , and a hardness of 6-7 by a hardness tester were press-molded to obtain elastic wool cotton for duvet with an inspection result of elastic fatigue recovery rate of 100% according to JISL-2001 standard. We have solved the problem and achieved the purpose. (See FIG. 2-reference numeral 3)
