(PIBSA 1000及びポリエチレングリコール 6000のABA構造を有するブレンド調製用相溶化剤の製造)
PIBSA1000(けん化値(SV)=86mg/gKOH)とPluriol(登録商標)E6000(ポリエチレンオキシド、Mn≒6000)との反応。
(フィラメントの製造)
全混合物に対して94.9重量%のMoplen HP560R、全混合物に対して5重量%のHD 05862N、並びに全混合物に対して0.1重量%の、ポリイソブチレン及びPEG(PIBSA/PEG 1000/6000)からなるブロックコポリマーからなる混合物を、一軸押出機に供給し、溶解して、混合する。次いで、得られた溶解物を、235℃にて、直径0.4mm及びL/D比=4のノズルを備えた紡糸プレートに通す。紡糸方法は、繊維の破断によって阻害されることはない。これにより、力価3.5dtex、比引裂き強度23mN/dtex、及び伸長性約420%のフィラメントが得られる。
実施例1の比較として、95重量%のMoplen HP560R(PP、MFI 25g/10分;230℃、2.16kg)及び5重量%のHD 05862N(HDPE、MFI 5g/10分;190℃、2.16kg)を上記押出機に投入し、同じ条件で紡糸する。しかし、繊維の破断が連続して生じるため、得られた溶融フィラメントは細いスレッドに引き伸ばすことができない。
(不織布材料の製造)
紡糸システムにおいて、3種類の異なる混合物をフィラメントに紡糸し、不織布材料を形成するために配置して、表1に記載した温度で結合する。
A)100%のMoplen HP560R(PP、MFI 25g/10分)
B)93.9%のMoplen HP560R、6%のHD05862N(HDPE、MFI 5g/10分)、0.1%のPIBSA/BEG 1000/6000
C)95.9%のMoplen HP560R、4%のDMDA 8907NT7(HDPE、MFI 6.75g/10分)、0.1%のPIBSA/PEG 1000/6000
この場合、直径0.6mmのノズルを備えた紡糸プレートが使用された。製造された不織布材料の基本重量は、20g/m2である。A)で得られた不織布材料を基準とする。得られたスレッドの機械的特性を、DIN 53 857に従って測定した。引張価(strain value)を表1に要約する。
