Fabric Handling, Cutting Room Support and Work Aids
This domain tests whether you understand what happens before the fabric reaches the needle - spreading, marker, shade and grain - and how to handle it at the machine without distorting it.
Cutting room support
- Fabric must relax before spreading so shrinkage does not shorten cut parts later.
- A marker carries the grain line, size ratio and notches. All plies must follow the same grain and, for pile or one-way prints, the same direction.
- Shade lots are kept together; a shade band difference across panels is a major defect.
- Checks, stripes and plaids are matched at the notches and at the seam line, not at the cut edge.
- Cut ticket and bundle ticket tie a bundle to its style, size, shade and quantity; losing the ticket breaks traceability.
Handling at the machine
- Let the feed dog move the fabric; guide with light fingertips two to three centimetres from the needle.
- Support the bulk on the table, not on your lap, so weight does not drag the seam.
- Sew with the grain where possible; never stretch knits or bias to make edges meet - match notches instead.
- Use tissue paper or a fine-fabric plate for delicate and coated materials, and a walking foot for pile and slippery layers.
Work aids
Magnetic and edge guides, seam guides, hemmers, binders, folders, compensating feet, needle positioner, automatic thread trimmer, stacker, foot lifter and good local lighting. Aids cut handling time and reduce variation between operators.
Worked example
A corduroy jacket shows panels that look different shades after assembly. Reasoning: pile fabrics have a nap, so every ply in the spread must run the same direction and every panel must be cut and sewn in that direction. The cause is a spread or cutting error, not the sewing tension, so the fix belongs in the cutting room.
Traps that cost marks
Pulling fabric to close a seam (causes waviness and needle deflection), mixing shade lots, and matching checks at the raw edge instead of the seam line.
