Because worsted fabrics can not undergo laundering, an attempt has recently been made to develope washable outer garments by providing wool/polyester blended fabrics with fusible interlinings. In this paper, the physical properties and fabric hand of wool 25%/polyester 75% blended fabrics interlined with fusible interlinings have been compared with those of blended fabrics without interlinings. Physical properties of these interlined fabrics, i.e., tensile, bending, shearing, compression, surface, thickness and weight were determined by the KES-F fabric testing system.
Relations were investigated between these physical properties and functions of the interlinings. The improvement of fabric properties providing with fusible interlinings and the change of physical properties of interlined fabrics have been investigated. Dry cleaning were made according to the AATCC Test Method 108-1963T and launderings were made according the #105 method (hand washing) prescribed in JIS (Japanese Industrial Standard) L0217.
The results are summarised as follows:
(1) Comparing with the properties of wool/polyester blended fabrics without interlinings, the bending properties of those interlined with the fusible interlining increase by five times or more, and shear properties increase by more than two times.
(2) In respect to the fabric hand of the interlined f abrics, it is observed that rigidity (Koshi in Japanese) increases by two times.
(3) Dry cleaning more changes the physical properties of wool/polyester blended fabrics used in this study than the laundering does.
(4) The fabric hand of these fabrics interlined with fusible interlinings is hardly deteriorated by the laundring. Thus, it is concluded that these interlined fabrics are much resistant to laundering.
