各実施例及び各比較例のポリウレタンフォームについて、バイオマス度、物性及び洗濯後乾燥性を測定した。測定結果を図1に示す。
バイオマス度(植物度)は、ASTM D6866-20に基づき、加速器質量分析法(AMS法)によって測定した値と、計算上の値の両方を示す。
ASTM D6866では、1950年の大気中の炭素14濃度の標準物質と資料の炭素14濃度測定を行い、その比をもってバイオマス度とすると規定されている。但し、現在の大気中の炭素14濃度は、年々増加しているため補正のためにこの値に係数をかけると規定されている。ASTM D6866-20に従った算出では、2020年の大気補正係数であるREF(pMC)=100.0を用いてバイオマス度の算出をした。
AMS法による測定値によってバイオマス度を評価した。評価基準は、AMS法による測定値が50%以上の場合「◎」、24~50%未満の場合「〇」、24%未満の場合「×」とした。
計算上の値は、式:バイオマス度=植物ポリオール添加部数/(全添加部数-ガスロス)
ガスロス=水添加部数/18×44により算出した。
上記のガスロス算出式における「18」は水の分子量、「44」は二酸化炭素の分子量である。
The biomass degree, physical properties, and dryability after washing were measured for the polyurethane foams of each example and each comparative example. The measurement results are shown in FIG.
The biomass content (vegetation content) indicates both a value measured by accelerator mass spectrometry (AMS method) and a calculated value based on ASTM D6866-20.
ASTM D6866 stipulates that the concentration of carbon 14 in a reference substance and a sample of carbon 14 concentration in the atmosphere in 1950 are measured, and the ratio thereof is defined as the degree of biomass. However, since the present atmospheric carbon-14 concentration is increasing year by year, it is stipulated that this value is multiplied by a coefficient for correction. In the calculation according to ASTM D6866-20, the degree of biomass was calculated using REF (pMC) = 100.0, which is the atmospheric correction factor for 2020.
The biomass degree was evaluated by the measured value by the AMS method. The evaluation criteria were "⊚" when the measured value by the AMS method was 50% or more, "◯" when it was 24 to less than 50%, and "X" when it was less than 24%.
The calculated value is the formula: degree of biomass = number of parts of plant polyol added / (total number of parts added - gas loss)
It was calculated by gas loss=number of parts added with water/18×44.
"18" in the above gas loss calculation formula is the molecular weight of water, and "44" is the molecular weight of carbon dioxide.
物性については、密度(JIS K7222)、25%硬さ(JIS K6400-2 6.7D法)、セル数(JIS K6400-1)、通気度(JIS K6400-7 A法)、引張強度(JIS K6400-5 5)、伸び(JIS K6400-5 5)、引裂強度(JIS K6400-5 6B)、乾熱歪(JIS K6400-4 4.5.2A法)、反発(JIS K6400-3)について測定した。 Regarding physical properties, density (JIS K7222), 25% hardness (JIS K6400-2 6.7D method), number of cells (JIS K6400-1), air permeability (JIS K6400-7 A method), tensile strength (JIS K6400 -5 5), elongation (JIS K6400-5 5), tear strength (JIS K6400-5 6B), dry heat strain (JIS K6400-4 4.5.2A method), and rebound (JIS K6400-3). .

Post-drying property evaluation and post-washing drying property comprehensive evaluation were performed. Compared to the slab foamed product, the molded foamed product has a skin layer that makes it difficult for water to escape. It was divided into slab foamed products and mold foamed products.
洗濯後吸水率は、縦型洗濯機を用い、図2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、各実施例及び各比較例のサンプルについて順に実施し、各洗濯コース終了毎に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洗濯後吸水率とした。各洗濯コース終了後の吸水率の算出は、次式による。
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)×100
各回の吸水率の値を図3に示す。なお、「洗濯前」は1回目洗濯コースの開始前である。

For the water absorption after washing, the first washing course, the second washing course, and the third washing course shown in FIG. The water absorption rate was calculated by measuring the weight of the sample each time it was washed, and the value of the water absorption rate after the completion of the third washing course was taken as the post-washing water absorption rate. The water absorption rate after each washing course is calculated according to the following formula.
Water absorption rate (%) = (weight of sample after each washing course - weight of sample before washing) / (weight of sample before washing) x 100
FIG. 3 shows the water absorption values for each time. "Before washing" means before the start of the first washing course.
The water absorbency after washing was evaluated according to the following criteria. For Comparative Example 1 and Examples 1 to 3 of the slab foamed product, "◎" when the water absorption after washing is less than 160%, "◯" when it is 160 to less than 200%, and "X" when it is 200% or more " For the molded foam products of Comparative Example 2 and Example 4, the post-washing water absorption rate was rated as "⊚" when it was less than 95%, "∘" when it was between 95% and less than 100%, and "X" when it was 100% or more.
脱水後吸水率は、3回目洗濯コース終了後に、図2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、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脱水後吸水率とした。各脱水コース終了後の吸水率の算出は、次式による。
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)×100
各回の脱水コース終了後の吸水率の値を図3に示す。
洗濯後脱水性評価は、次の基準で評価した。スラブ発泡品の比較例1及び実施例1~実施例3については、脱水後吸水率が120%未満の場合「◎」、120~185%未満の場合「〇」、185%以上の場合「×」とした。モールド発泡品の比較例2及び実施例4については、脱水後吸水率が90%未満の場合「◎」、90~95%未満の場合「〇」、95%以上の場合「×」とした。
After completion of the third washing course, the water absorption after dehydration was calculated by performing the first dehydration course and the second dehydration course shown in FIG. , the water absorption after the second dehydration course was taken as the post-dehydration water absorption. The water absorption after each dehydration course is calculated according to the following formula.
Water absorption rate (%) = (weight of sample after each dehydration course - weight of sample before washing) / (weight of sample before washing) x 100
FIG. 3 shows the water absorption values after each dehydration course.
Dehydration property after washing was evaluated according to the following criteria. For Comparative Example 1 and Examples 1 to 3 of the slab foamed product, "◎" when the water absorption after dehydration is less than 120%, "◯" when it is 120 to less than 185%, and "X" when it is 185% or more " For the molded foam products of Comparative Example 2 and Example 4, the water absorption after dehydration was rated as "⊚" when it was less than 90%, "∘" when it was 90 to less than 95%, and "X" when it was 95% or more.
24時間乾燥後吸水率は、2回目脱水コース終了後のサンプルを24時間室温(20~28℃を室温という。)で放置し、その後のサンプルの重量から吸水率を算出した。24時間乾燥後の吸水率は次式による。
24時間乾燥後の吸水率(%)=(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)×100
24時間乾燥後の吸水率の値を図3に示す。
洗濯後乾燥性評価は、次の基準で評価した。スラブ発泡品の比較例1及び実施例1~実施例3については、24時間乾燥後吸水率が1%未満の場合「◎」、1~3%未満の場合「〇」、3%以上の場合「×」とした。モールド発泡品の比較例2及び実施例4については、24時間乾燥後吸水率が5%未満の場合「◎」、5~10%未満の場合「〇」、10%以上の場合「×」とした。
The water absorption after drying for 24 hours was calculated by allowing the sample after the second dehydration course to stand at room temperature for 24 hours (20 to 28° C. is referred to as room temperature) and then calculating the water absorption from the weight of the sample. The water absorption after drying for 24 hours is calculated by the following formula.
Water absorption after drying for 24 hours (%) = (weight of sample after standing for 24 hours) / (weight of sample before washing) x 100
