The constituent fiber flexible which has low temperature activity and the sheet null backing material sheet fiber flexible which

摘要

Because as for this invention, HPLC (high pressure liquid chromatography) or GC (gas chromatography) with being something regarding the composition fiber soft which includes the positive ion surface active agent where ratio of the alkyl substituent of C7 - C21 which were analyzed is 0.6 or more and the seat fiber soft which includes this as a active ingredient, as for the composition fiber soft of this invention, it has the melting and dispersed effect which is superior low even in the warm water, the seat fiber soft which includes this, using when rinsing in laundry process, carries out the electrification prevention effect and the fiber soft effect which are superior in the fiber and the clothing.
