Fabric Process and Shade Grouping

Shade grouping 

Mainly denim fabric shade grouping must do after actual blanket wash, as a process 100% (roles cut panel 8-10 Inch) cut out of cut 8*8 size must be attach as a mat. Per mat can include 09 roles part stitch together . Each and every blanket need attach Master roll fabric/Sample yards cut pcs to compare and match the color.

Including all fabric consignments blanket must be wash as per correct stranded wash recipe and color need match with selected control fabric.

If selected controls fabric color must be matching with target

After wash blanket parts separated and can group as per taper sequence. It can be group shade A. B .C. D. E etc….

Shade label must be attached correctly in sewing.

Washing department wash load by following shade label. Same shade will be load as one load, output also will be looks same.

 Shrinkage test- Shrinkage cut panel also can cut from initial cut pcs which cut for blanket.

 Physical test

 Color fastness test

 Rubbing test

Fabric Process and Shade Grouping

Note S/S – (Side to side) S/M Side to Middle

Tailing check – Roll Beginning Middle and end shading check.

P1A – Dimensional stability check

If you follow blanket/Shade grouping process correctly easy to handle denim and twill fabric in wash stage.

Also it will help to reduce color dark light in same bath and shade variations in bulk stage.

Fabric Process

This department mainly deals with the fabric related activities. Fabric inspection department is playing a vital role in the organization.
