1) Heat Transfer Nomex felt is used on a heat transfer printing calender. Synthetic fabrics are usually printed on this calender using high temperatures (up to 230°C / 450°F). The pre-printed paper carries the dyestuffs, which are then sublimated on the fabric using high temperature.
The purpose of the sublimation felt is to press the fabric against the printed paper, both against the heated drum. The contact between the fabric and the printed paper needs to be long enough, to ensure the transfer of the dyestuffs to the fabric. Heat transfer printing is an economical way to print synthetic fabrics.
These machines can also be used for the following processes :
Laminating,or Roll to Roll printing, sublimation printing
Placard transfer printing (banners)
These Nomex felts are used on the following machines : Klieverik, Monti, Transmatic, Lemaire, Practix, Sorim, Studio FX, Stork, Bates, Wuppertal, Kristall, Sublistatic, Gessner, Bizmak, S.T.M., Singer, KMT, MOGK, TURAL MAKINA,...
2)The purpose of a sanforizing machine or a shrinking machine is to pre-shrink, stabilize cotton fabrics and mixed cotton fabrics such as Denim.
It is made of 2 units :
the shrinking unit in which the compressive shrinkage is given by a thick Sanfor rubber belt using steam and mechanical pressure
the drying unit, also called the Palmer unit, in which the fabrics are dryed by an endless Sanfor polyester felt, which is called sanforizing felt, Palmer felt,polyester felt,nomex felt,Sanforizing Needle Felt, Sanfor blanket or drying felt.
