Layer Chart, Marker & fabric length/width:


Layer Chart:-Layer chart is one kind of sheet which contain all the information like fabric item, color info, size assort, layer qty etc. Before layer spreading QA must check layer sheet/chart which provided by cutting supervisor. If all information found ok then QA check marker length/width on fabric, fabric width, Ticket information of roll, shade separation report, lab test  report, fabric inspection report & running shading report every thing are ok then QA allow to layer spreading. QA inspector check 100% layer.

(b)Fabric Unrolling/Relaxation: For stretchable/spandex/Knitted fabrics must need to be unroll/relax for 12 hours before cutting. Layer qty depends on type of fabric, e.g; for Polar fleece (360 gms)- 40~45 layers. Coated fabrics – 60~80 layers, Codura fabrics – 40~50 layers, Taffeta 210T p/d, w/r- 150~180 layers. Micro fleece- 60~70 layers. 

(c)Defects Check on Layer: Based on MCD QA’s shading report cutting QA double check the running-shading & side-center shading in cutting table before spreading the layer same as MCD QA procedure. Cutting Inspector check every layer care fully for weaving (construction), dyeing, cleanness & finishing defects of fabric.

(d)Requirements of Stripe fabrics cutting: For stripe fabric cutting, marker should use Stripe Matching Marker. QA check fabric stripes is bias or not, if fabric stripe is bias then no accept for cutting, if stripe is ok then use the Stripe Matching Marker for cutting. Layer spreading must be carefully to avoid any bias & bow. To avoid any bias stripe of fabric need to use Pinup system in layer.

(e)Cut Panel Inspection: As per MCD fabric inspection report if fabric is ok then cut panel check randomly by cutting qa. We are apply cut pnl inspection method for such kind of fabric panel’s by inspecting some top-middle-bottom pcs of bundle(front, back ,slv). If fabric quality not ok(B/C grade), its need 100% cut pnl inspection.

(f)How to find defect: Wrong cutting defects: To find out wrong cutting defects (size mistake, over cutting) check and compare with the assortment and marker. For bias cutting we check cut pnl from top-middle–bottom of bundle and compare with marker/pattern.

To find number mistake: QC first take two bundle of different part ( like slv to slv or front to front), then compare some panel to each other by serial wise – e.g; take 1st  20 pcs from each bundle & check with each other. If have 2/3 group shade and if have mistake/one missing serial numbering in serial panel, then panel will not match each other from different shade/missing numbering. So qc can understand that is number mistake.

Bundle mistake:  If mistake the assort in one size at bundling time, e.g; bind the     bundle for S-size, B with A i/o B with B then called that is bundle mistake.

Parts Replacing:   After find out the rejection panel qc register the panel number in register book & give that panel to cutting person. Cutting person compares that    panel with same shade fabric and shown to qc, if ok qc tell to cut from that shade and maintain register.      

Cause of shading: Bundle mistake, Numbering mistake and Wrong shade panel replacement etc.
