Plant Technology Garment Training Quiz - 2

1. What is not a prerequisite of a fabric or a trim to be bondable?

• The fabric should be hydrophobic.

• Fabric/trim should be free of silicone finishes

• Fabric/trim should be finished at a higher temperature.

• The dye of the fabric needs to be heat resistant

By using bonding technology, it is possible to,

• Obtain a clean finish

• Achieve less bulky seams.

• Enhanced appearance with flatter, smoother profile.

• All above.

What is not one of the three parameters of flat press bonding?

• Temperature

• Speed

• Pressure

• Time

The glue line temperature is,

• The temperature where the adhesive begins to become sticky.

• The glass transition temperature of the glue.

• The actual temperature range to which the adhesive should be exposed to get an optimum bond.

• The temperature at which glue lay down is done.

The adhesive polymer group corresponding to Bemis 3000 series is,

• Polyolefin

• Polyamide

• Polystyrene

• None of the above.

3 mil is equal to

• 75 micrometers

• 25 micrometers

• 50 micrometers

• 30 micrometers

Select the wrong statement about Ultrasonic cutting technology.

• Up to four times faster than traditional sewing machines

• Fraying and unraveling of bonded edges and seams are virtually eliminated

• Cost-effective

• Cotton fabrics are recommended for ultrasonic cutting applications

Select the wrong answer about laser cut technology,

• Is highly accurate.

• Needs to have at least 6mm as the narrowest gap in Laser cut designs

• Yields excellent cut quality

• Gives minimum wastage

Choose the correct statement.

• During glue lay-down operation, the actual temperature reaches up to the GLT of the adhesive.

• To achieve optimum bonding level, the glue must penetrate 1/3 into one fabric, retain 1/3 in the middle, and the remaining 1/3 to the other fabric.

• Cotton fabrics are recommended for laser-cut operations.

• Parameters affecting continuous bonding are temperature, pressure, and time.

Which of the following is not a glue supplier?

• Best Pacific

• Bemis

• 3M

• Framis
