    • A step pile fabric according to the present invention contains a non-shrinkable fiber, and a shrinkable fiber containing a modacrylic copolymer. A composition of the shrinkable fiber containing the modacrylic copolymer contains a polymer composition obtained by mixing i) 60 to 99 parts by weight of a copolymer (A) containing 35 wt % to 98 wt % of acrylonitrile, and 2 wt % to 65 wt % of a total amount of 0.5 wt % to 5.0 wt % of a sulfonic-group-containing monomer and other vinyl monomer, and ii) 1 to 40 parts by weight of a copolymer (B) containing 0 wt % to 90 wt % of acrylonitrile, 2 wt % to 40 wt % of a sulfonic-group-containing monomer, and 0 wt % to 80 wt % of other vinyl monomer containing no halogen. A dry heat shrinkage S of the shrinkable fiber at 130° C. for 5 minutes after dyeing is 15% to 40%. In this way, by performing dyeing using a cationic dye in a low-temperature region so as to suppress shrinkage during dyeing and performing a dry heat treatment after dyeing, a pile fabric with large height difference is provided.
    • 根据本发明的阶绒布织物包含不可收缩纤维和含有改性丙烯酸共聚物的可收缩纤维。 含有改性丙烯酸共聚物的收缩性纤维的组合物含有通过混合i)60〜99重量份含有35重量%〜98重量%丙烯腈的共聚物(A)和2重量%〜65重量% 的总量为0.5重量%至5.0重量%的含磺酸基单体和其它乙烯基单体,和ii)1至40重量份含有0重量%至90重量%丙烯腈的共聚物(B) ,2重量%至40重量%的含磺酸基单体和0重量%至80重量%的不含卤素的其它乙烯基单体。 可收缩纤维在130℃下染色5分钟的干热收缩率为15%〜40%。 以这种方式,通过在低温区域中使用阳离子染料进行染色,以抑制染色时的收缩和染色后进行干热处理,提供高差大的绒头织物。
