While most Chicago flatwork ironer belt or Chicago ironer can easily handle cotton, poly cotton or cotton-rich fabrics, it becomes a bit hard to switch from one type of fabric to another. Problems might also arise when you mix two or three different types of cloths in one run because this could grey polyester blends. This is why you need, as a customer, to look for an experienced Chicago ironer or laundry flatwork ironer.
Here is how a Chicago flatwork ironer belt experts or Chicago ironer experts can help deal with ironing difficult fabrics:
1. 100% cotton: To get the best end results — meaning high quality ironing — the fabric should be ironed at 50 percent of moisture and at around 200 degree Celsius. It can be difficult to remove creases if the fabric has less than 40 percent moisture.
2. Poly cotton: The laundry flatwork ironer will set the maximum temperature to be 165C (equivalent to 7 bar steam) to obtain the best results. Remember that raising the temperature above the manufacturer recommended level of 150C means the manufacturer will not be responsible for any problems that occur as a results. These problems are likely to result if the fabric is distorted by roll-to-roll-stretch and bed drag. You can deal with these difficulties by lowering the bed temperature to about 165C and running waxing cloth more frequently. Run with wax when starting a eight-hour shift and then shift to every hour without adding wax.
Apart from dropping the bed temperature to solve the problem, Chicago flatwork ironer belt or Chicago ironer also solve the problem by raising the ironing moisture content and slightly raising the ironing speed. Doing this also solves static problems with polyester and poly-cotton.
An over-heated polyester blend can cause concertina creasing and leading edge rolling when entering an in-running nip successfully. The problem worsens when the roll is undersized relative to the bed or when the bed is distorted. This is more likely to occur when dealing with older cast-steel beds. This is avoided by stress relieving modern beds. The problem can be temporary solved by operating at correct bed temperature (around 165C maximum) or running waxing cloth more frequently. Re-springing can help if a rolled leading edge flattens the ironer springs, which makes rolling to get significantly worse.
3. Cotton-rich: Performance of cotton-rich fabrics in ironer varies depending on how polyester fibres have been incorporated into the yarns. A intimate blend loses its strength at 167C when the polyester cotton starts to soften. The roll-to-roll stretch and bed drag will stretch the fabric in the machine direction.
Cotton-rich are more likely to record problems with elasticity after the first one or two wash unlike than 100% cotton fabrics. This should be dealt with by adjusting the roll-to-roll stretch to near 0.1% and setting the right ironer temperature.
