Understanding CAD Plotting and Fabric Spreading Techniques in Textile Manufacturing

This lecture covers crucial concepts in CAD plotting, focusing on the use of plotters similar to printers for fabric design. It delves into the shade sequencing process to ensure consistent shade across fabrics, utilizing shade cards and layering techniques. The terms "layer" and "lay" are defined, explaining their importance in fabric cutting. It also discusses splitting paper for separating different fabric types and the spreading process, introducing the two main types of spreading: face-to-face and face-up.

Presentation Transcript

  1. Lecture 15 CAD (GGT)

  2. Plotting • The instrument used is called plotter • Plotter is just like a printer • It prints the marker as we have made it

  3. Shade Sequence • This is the process of organizing all the shade in a fabric in a specific sequence to avoid shade difference at the end of the process. • For this purpose shade card is made • Dark to light • Light to dark

  4. Layer and Lay • Layer • One ply of fabric in a spread to cut is known as layer or ply • Lay • Lay is the whole sum of fabric to be cut in one go this is also known as spread

  5. What is a splitting paper/ Splitter • Splitting paper or splitter is used to separate two different type of fabrics in the same lay • Separation of fabrics of different shades • Separation of fabrics of different colors

  6. Spreading • The process of superimposing fabric layers to get the required number of garments at a time

  7. Types of Spreading • Basically there are two types of spreading • Face to face / Back to back / Two way • Face-up / One way
