Remarks: The production process, followed by the Dye-house of Landmark Textile Mills Ltd. is impressive. The processes are being carried out very quickly and accurately. Due 46

  47. to the excellence of process, machineries and lab trials very few cases of re-dyeing is performed. CHAPTER – VI QUALITY ASSURANCE SYSTEM 47

  48. Quality Policy: It is the policy of Landmark Textile Mills Ltd. to produce quality dyed knit fabrics that meet the customer’s expectations & needs. To implement this policy the top management of Landmark Textile Mills Ltd. is committed to provide adequate resources in terms of good raw materials and trained personnel & continually improve / upgrade its processes and systems. The quality control policy of Landmark Textile Mills Ltd. is stated below-  Leadership program from the top.  In-process quality control during manufacturing operation.  Evaluation programs in all areas of knitting, dyeing, cutting, sewing and finishing.  Maintain chain of responsibility.  Follow strict stuffing, auditing and reporting.  Use inspection machines in required points.  Maintain standard AQL.  Sufficient lighting and sanitation.  Final inspection prior to packaging.  Meeting the appropriate expectations of clients. Quality Assurance Procedure: Landmark Textile Mills Ltd. assures the quality of their products in the following three steps: 1. In laboratory. 2. In dyeing section 3. In finishing section The quality assurance procedures are described below: In laboratory:    Swatch card from buyer according to their requirement is received. Recipe prediction for sample dyeing using CCMS. Sample dyeing until matching with the swatch card. Acceptable color difference is less than 1. If matching is OK, then it is sent to the buyer for approval.  In dyeing section:  After approval form the buyer, sample dyeing is done in dyeing m/c, in dyeing shed & again matched with the approved sample. If result is OK, then balk production is commenced.  48

  49. During dyeing process, before the final acid wash, samples are taken and checked for accurate shade matching. After dyeing sample is collected & matching is done. Rubbing and wash fastness tests are carried out.   In finishing section:   Correctly dyed, after treated & matched fabrics are allowed for finishing. By usinga series of finishing machines correct width, softness & appearance are maintained according to requirements. Then sampling is done several times to test GSM, Shrinkage & fastness properties. Finally fabric is inspected & prepared for delivery.   Inspection area:  Shade match of fabric  G.S.M.  Fabric diameter  Spirality  Shrinkage (%)  Length wise  Width wise  Wash fastness  Rubbing fastness  Faults  Dyeing faults  Knitting faults  Finishing faults Knitting Faults   Hole  Slub  Needle mark  Stripe  Missing yarn  Contamination Dyeing Faults   Uneven shade  Running shade  Fastness property  Dye spots and marks Finishing Faults  49

  50.  GSM variation  Spirality  Shrinkage control  Marks PROBLEMs ENCOUNTERED IN DYEING: Uneven Dyeing   1. It can be caused due to rapid addition of dyes and chemicals. For this purpose the dosing of soda ash should be maintained properly. 2. Pressure difference. 3. Over loading in the m/c. 4. Yarn lot mixing. 5. Improper control of temperature. 6. Less amount of leveling agent. 7. Improper pretreatment. Uneven Shade in Rope to Rope   1. Improper rope length in each chamber. 2. Improper fabric flow speed in each nozzle. Off Shade  1. Improper M: L ratio. 2. Lower amount of auxiliaries. 3. Improper mixing of dyestuffs. Dye Spots   This is most common fault caused by operator not correctly mixing and thoroughly dissolving dyestuffs in the right amount of water. Batch to Batch Shade Variation   If any of parameters of dyeing are changed then it will produce problems in batch to batch consistency. In order to avoid this defect the following steps should be followed- 1. Maintain the same liquor ratio. 2.Check that the fabric has the same dye affinity. 3. Use the same standard program procedures for each batch. 4. Making sure that the operators add the right bach of chemicals at the same time & temperature in the process. 5. Check the water supply daily especially ph, hardness & Na2CO3content. 50
