In hot and humid condition, the matted wool fiber assembly will
gradually contract and cross under the repeated effect of the
external mechanical force, which is called fulling property. The
cardigan processing technology by means of this feature is called
fulling finish. Fulling is the major content of finishing
technology of cardigan.
To create favorable condition and accelerate fulling speed,
generally the chemical reagent is added. Now the fulling finish
technology is mainly applied to woolen cashmere sweater such as
cashmere, camel wool, rabbit hair, lamb wool, Shetland wool, etc.
In addition, the worsted cashmere sweater improves appearance
through the short-time detergent washing, wet finishing and fulling
at normal temperature.
The common 100% wool made through high temperature fulling is
different from wool in the aspect of appearance and style.
