Description
上記の繊維ウェブは、一対のフラットロールで圧接処理されたのち、一方のフラットロールに所定時間押し当てられて片面が平滑化され、壁装材用不織布に形成される。 The fiber web is pressure-welded with a pair of flat rolls and then pressed against one of the flat rolls for a predetermined time to smooth one side and form a non-woven fabric for wall covering.
この熱処理加工におけるフラットロールの表面温度は、繊維ウェブの表面に存在するフィラメントを構成する、最も融点の低い重合体の融点に対して、３０℃以上１２０℃以下低いことが好ましく、４０℃以上１１０℃以下低いことがより好ましく、５０℃以上１００℃以下低いことが最も好ましい。即ち、この融点を（Ｔｍ）とした場合、フラットロールの表面温度は、（Ｔｍ－３０）℃以下（Ｔｍ－１２０）℃以上であることが好ましく、（Ｔｍ－４０）℃以下（Ｔｍ－１１０）℃以上がより好ましく、（Ｔｍ－５０）℃以下（Ｔｍ－１００）℃以上が最も好ましい。 The surface temperature of the flat roll in this heat treatment process is preferably 30 ° C. or higher and 120 ° C. or lower, preferably 40 ° C. or higher and 110 ° C. or higher, with respect to the melting point of the polymer having the lowest melting point constituting the filament existing on the surface of the fiber web. It is more preferably lower than ° C., and most preferably 50 ° C. or higher and 100 ° C. or lower. That is, when this melting point is (Tm), the surface temperature of the flat roll is preferably (Tm-30) ° C or lower (Tm-120) ° C or higher , and is preferably (Tm-40) ° C or lower (Tm-110). ) ° C. or higher is more preferable, and (Tm-50) ° C. or lower (Tm-100) ° C. or higher is most preferable.
（熱圧着）
上記繊維ウェブを上下１対のフラットロールにてフラットロール表面温度１６０℃、線圧５８８Ｎ／ｃｍで熱圧着し、この圧着されたシートをこの加熱圧接部から連続して一方のフラットロールの表面へ１２０ｃｍにわたって２．９秒間接触させた。
(Thermocompression bonding)
The fiber web is thermocompression-bonded with a pair of upper and lower flat rolls at a flat roll surface temperature of 160 ° C. and a linear pressure of 588 N / cm, and the pressure-bonded sheet is continuously applied to the surface of one of the flat rolls from the heat-pressed portion. The contact was made over 120 cm for 2.9 seconds.
［比較例２］
実施例１同様にして繊維ウェブを得た。この繊維ウェブを上下１対のフラットロールにてフラットロール表面温度１６０℃、線圧６０ｋｇｆ／ｃｍで熱圧着し、この圧着されたシートをこの加熱圧接部から連続して一方のフラットロールの表面へ１２０ｃｍに亘って３．２秒間接触させた後、エンボスロールによる部分的熱圧着を行い、繊維径１４μｍ、目付９０ｇ／ｍ２のスパンボンド不織布を得た。得られた壁装材用不織布は、通気量が５０ｃｃ／ｃｍ２／秒、厚さが０．３２ｍｍ、平滑面の表面粗さＳＭＤが２．３２μｍ、目付当たりのタテ引裂強力が０．９９Ｎ／（ｇ／ｍ ２）であり、交点以外の繊維同士が融着して膜状（フィルム状）となった部分は見られなかった。
[Comparative Example 2]
A fiber web was obtained in the same manner as in Example 1. This fiber web is thermocompression-bonded with a pair of upper and lower flat rolls at a flat roll surface temperature of 160 ° C. and a linear pressure of 60 kg f / cm, and the pressure-bonded sheet is continuously applied to the surface of one flat roll from the heat-pressed portion. After contacting the surface for 3.2 seconds over 120 cm, partial thermocompression bonding was performed with an embossed roll to obtain a spunbonded nonwoven fabric having a fiber diameter of 14 μm and a grain size of 90 g / m 2 . The obtained non-woven fabric for wall covering has a ventilation rate of 50 cc / cm 2 / sec, a thickness of 0.32 mm, a smooth surface roughness SMD of 2.32 μm, and a vertical tear strength of 0.99 N / sec. It was (g / m 2 ), and no part where the fibers other than the intersections were fused to form a film-like (film-like) was observed.
