前記ポリオール成分は、ヒマシ油とセバシン酸との反応物、及び、石油由来のポリオールを含み、
ＡＳＴＭ Ｄ６８６６－２０によって測定されるバイオマス度が５０％以上であることを特徴とするポリレウレタンフォーム。 In a polyurethane foam obtained from a polyurethane foam composition containing a polyol component, a polyisocyanate, and a blowing agent,
The polyol component includes a reaction product of castor oil and sebacic acid, and a petroleum-derived polyol,
A polyurethane foam characterized by having a biomass degree of 50 % or more as measured by ASTM D6866-20.
以下の測定方法で測定された前記ポリウレタンフォームの洗濯後吸水率、脱水後吸水率、２４時間乾燥後吸水率は、The water absorption rate after washing, water absorption rate after dehydration, and water absorption rate after 24 hours drying of the polyurethane foam were measured by the following measurement method:
前記ポリウレタンフォームがスラブ発泡品の場合、前記洗濯後吸水率が２００％未満、前記脱水後吸水率が１８５％未満、前記２４時間乾燥後吸水率が３％未満であり、When the polyurethane foam is a slab foam product, the water absorption rate after washing is less than 200%, the water absorption rate after dehydration is less than 185%, and the water absorption rate after drying for 24 hours is less than 3%,
前記ポリウレタンフォームがモールド発泡品の場合、前記洗濯後吸水率が１００％未満、前記脱水後吸水率が９５％未満、前記２４時間乾燥後吸水率が１０％未満であることを特徴とするポリウレタンフォーム。When the polyurethane foam is a molded foam product, the polyurethane foam has a water absorption rate of less than 100% after washing, a water absorption rate of less than 95% after dehydration, and a water absorption rate of less than 10% after drying for 24 hours. .
洗濯後吸水率の測定方法は、縦型洗濯機を用い、表１に示す１回目洗濯コース、２回目洗濯コース、３回目洗濯コースを、前記ポリウレタンフォームのサンプルについて順に実施し、各洗濯コース終了毎に前記サンプルの重量を測定して吸水率を算出し、３回目洗濯コース終了後の吸水率の値を前記洗濯後吸水率とした。The method for measuring the water absorption rate after washing is to use a vertical washing machine and perform the first washing course, second washing course, and third washing course shown in Table 1 on the polyurethane foam sample in order, and then wait until the end of each washing course. The weight of the sample was measured each time, the water absorption rate was calculated, and the value of the water absorption rate after the third washing course was taken as the water absorption rate after washing.
洗濯後吸水率（％）＝（各回の洗濯コース後サンプルの重量－洗濯前サンプルの重量）／（洗濯前サンプルの重量）×１００Water absorption rate after washing (%) = (Weight of sample after each washing course - Weight of sample before washing) / (Weight of sample before washing) x 100
脱水後吸水率の測定方法は、３回目洗濯コース終了後に、表１に示す１回目脱水コースと２回目脱水コースを順に行い、各回の脱水コース終了毎に、前記サンプルの重量を測定して吸水率を算出し、２回目脱水コース終了後の吸水率を前記脱水後吸水率とした。The method for measuring the water absorption rate after dehydration is to perform the first dehydration course and second dehydration course shown in Table 1 in order after the third washing course, and measure the weight of the sample after each dehydration course to determine the water absorption. The water absorption rate was calculated, and the water absorption rate after the second dehydration course was defined as the water absorption rate after dehydration.
脱水後吸水率（％）＝（各回の脱水コース後サンプルの重量－洗濯前サンプルの重量）／（洗濯前サンプルの重量）×１００Water absorption rate after dehydration (%) = (Weight of sample after each dehydration course - Weight of sample before washing) / (Weight of sample before washing) x 100
２４時間乾燥後吸水率は、２回目脱水コース終了後の前記サンプルを２４時間室温（２０～２８℃を室温という。）で放置し、その後の前記サンプルの重量から前記２４時間乾燥後吸水率を算出した。The water absorption rate after 24-hour drying is calculated by leaving the sample after the second dehydration course at room temperature for 24 hours (20 to 28°C is referred to as room temperature), and then calculating the water absorption rate after 24-hour drying from the weight of the sample. Calculated.
２４時間乾燥後吸水率（％）＝（２４時間放置後のサンプルの重量）／（洗濯前のサンプルの重量）×１００Water absorption rate after drying for 24 hours (%) = (Weight of sample after being left for 24 hours) / (Weight of sample before washing) x 100
