  1. 1. Production process in garment manufacturing Prepared By: Gaurab Kumar Baishya 15020441094 A-11 Mentored By: Mr. Binith Managing Director, Iris International
  2. 2. Primary processes involved Designing/Sketching Prototyping Manufacturing Inspection
  3. 3. Designing/Sketching Design/ Sketch : For designing the sketch of the dress to be manufactured. Rough sketches which are analyzed by panel of designers. Few are selected to form a pattern. Pattern Design : The pattern maker now develops first pattern for the design in any one standard size. This is made by pattern drafting method and the purpose of making this pattern is to create the sample garment for test fit. Sample Making : First few patterns are sent into assembling unit. Usually stitched on calico or muslin to reduce cost. The sample created is analyzed for pattern fit and design. It is then reviewed by panel of designers for rectification if any.
  4. 4. Prototyping Production Pattern : Pattern design is now made into production pattern for mass production. It is usually made on basis paper. Usually method of CAD/CAM is preferred over manual method. Measurements include 1. Direct Sample, 2. measurement chart, 3. Actual body size, 4. Easy allowance, 5. Sewing Allowance. Grading : Purpose is to create patterns in different standard sizes. Patterns can be large, medium or small. Usually the changes are made through CAD/CAM as manual process of grading is cumbersome. Marker Marking : Marking is an important step to assess the optimum need of fabric in garment manufacturing. Markers with help of adhesive are attached to fabric so that minimum amount of fabric gets wasted during cutting operations. Spreading : With the help of spreading machines, fabric is stacked on one another in reaches or lays that may go over 100 ft (30.5 m) long and hundreds of plies (fabric pieces) thick.
  5. 5. Manufacturing Cutting : fabric is cut with help of cloth cutting machine. The band cutters have rotary blades and reciprocal blades which can saw up and down. Nowadays laser beams are used to cut the fabric in desired shapes. Sorting/Bundling : The cloths are sorted according to their size and design in bundles. This step requires much precision because making bundles of mismatched patterns can create severe problems. A marker is attached with each bundle along with a style size specifications. Sewing/Assembling : Sewing stations in which different parts of cut pieces are stitched together. There are many operators who perform single operation. One operator may make only straight seams, while another may make sleeve insets. Yet another two operators can sew the waist seams, and make buttonholes. Finally, the sewn parts of the garment, such as sleeves or pant legs, are assembled together to give the final form to the clothing. Inspection : Open seams, wrong stitching techniques, non- matching threads, and missing stitches, improper creasing of the garment, erroneous thread tension and raw edges are some of the sewing defects which can affect the garment quality adversely. During processing the quality control section needs to check each prepared article against these defects Pressing/Finishing : Molding may be done to change the finished surface of the garment by applying pressure, heat, moisture, or certain other combination. Pressing, pleating and creasing are the basic molding processes. Creasing is mostly done before other finishing processes like that of stitching a cuff. Vertical and form presses is automated machines. Perform simple pressing operations, such as touching up wrinkles in knit shirts, around embroidery and snaps, and at difficult-to-reach places on garments
  6. 6. Inspection Garment defects : Broken or defective buttons, snaps, stitches, different shades within the same garment, dropped stitches, exposed notches and raw edges, fabric defects, holes, faulty zippers, loose or hanging sewing threads, misaligned buttons and holes, etc. all can lead to the end of a brand name even before its establishment. Sizing Defects : Wrong gradation of sizes, difference in measurement of various parts of a garment like sleeves of XL size for body of L size garment can deteriorate the garments beyond repair. Color defects : Variation of color between the sample and the final garment, wrong color combinations and mismatching dyes should always be avoided. Sewing Defects : Open seams, wrong stitching techniques, non- matching threads, missing stitches, improper creasing of the garment, erroneous thread tension and raw edges are some of the sewing defects which can affect the garment quality adversely.
