    Step 3: Water absorbency test (Soak test):                                 Table 1
                •  Cut 5 cm yarn pieces.                                    Yarn       Absorbency       Suitability

                •  Dip each in water for 2 minutes.                   Cotton yarn
                •  Remove and check water absorption.                 Wool yarn
                                                                      Polyester yarn

                TASK 3: Fabric identification and suitability for wet processing
                Step 1: Visual and Feel Test:                         Step 3: Simple Dye Drop Test (Optional):
                •  Take one  sample  fabric  and observe  its surface   •  Apply a drop of dilute water-soluble dye on fabric.
                   (weave/knit), weight, thickness, and texture.      •  Observe how quickly and how well it is absorbed.
                •  Feel the softness, drape, and flexibility.
                                                                                           Table 2
                •  Likewise take all the samples one by one, observe       Fabric      Dye uptake         Result
                   its appearance and feel and write it in the notebook.
                                                                         Cotton
                Step 2: Water Drop Absorbency Test:
                                                                         Wool
                •  Place a drop of water on one fabric sample.           Silk

                •  Observe speed and spread of water.                    Polyester
                •  Likewise observe on all the fabric samples. And note   Step 4:  Yarn  Pull  Test  (For  Fabric  Structure
                   it on the below mentioned table 1                         Identification):
                                     Table 1                          •  Using a needle or pin, pull threads from fabric edge:
                     Fabric       Absorption        Spread              -  Woven fabrics: Straight yarns (warp and weft).
                    Cotton                                              -  Knitted fabrics: Loops.
