Abstract

<P>PROBLEM TO BE SOLVED: To provide a deodorant down and deodorant bedding, having excellent deodorant properties because sleep is obstructed by the down which is used as an inner pad for the bedding, and which has a peculiar smell caused by the generation and propagation of bacteria by a large amount of sweat when sleeping. <P>SOLUTION: The deodorant down is obtained by subjecting the down to a treatment such as anionization of the down by an oxidizing agent, and increasing of cationic seats in the down by lowering the pH of a treating bath, and fixing a deodorant organic compound such as catechin, or a deodorant inorganic compound such as an oxide, a silicate and the like of zinc, silver or the like, to the treated down. When the bedding is formed by fixing the deodorant material to both of the inner pad and the ticking, more deodorant effects are exhibited. <P>COPYRIGHT: (C)2004,JPO

EXAMPLES The present invention will be described in more detail below with reference to examples. In the examples, deodorant performance was evaluated by the following method. (1) Deodorizing performance of feathers 1 g of feathers was placed in a 10 cm square bag made of polyester fabric, and this bag was placed in a 3 liter tetra bag, and 600 ml of gas adjusted to the initial concentration was injected into the tetra bag. Leave for 3 hours. Three
After a lapse of time, measure the gas concentration A in the tetra bag with a test tube. As a blank, the concentration B of the gas is measured in the same manner with no feather. The deodorization rate (%) was calculated by the following formula. Deodorization rate (%) = ((B−A) / B) × 100 The types of gas used for evaluation and their initial concentrations are as follows. 1) Ammonia initial concentration 900ppm 2) Hydrogen sulfide initial concentration 100ppm 3) Acetic acid initial concentration 100ppm 4) Isovaleric acid initial concentration 10ppm (2) Deodorant performance of the futon A 10cm square futon with 1g of feathers was prepared. Then, the futon is put into a tetra bag of 3 liters, 600 ml of gas adjusted to the same initial concentration as in (1) is injected into the tetra bag, and left for 3 hours. After 3 hours, measure the gas concentration A in the tetra bag with a test tube. Similarly, without using a blanket as a blank, the gas concentration B is measured to calculate the deodorization rate of the duvet. In order to evaluate the durability of washing, unwashed futon and JI
The deodorizing performance after washing 5 washings according to the SL0217 103 method was also evaluated.
