Avl management has made all out efforts to implement systematic production line up and highest level of quality control for the Rmg products produced in the factory. For this purpose Avl management has taken keen interest for smooth and trouble free management in the management systems.
|
||||||||
|
||||||||
|
||||||||
|
||||||||
|
||||||||
All the management systems as mentioned above must run in flawless manner so that all pre-planned job schedules can be maintained timely. To keep the consistency in product quality along with its timely delivery, we undertake our efforts to maintain proper quality control in three parameters which must be analyzed during the phases of :
|
||||||||
|
||||||||
|
||||||||
|
||||||||
As such, the Avl factory continuously motivate his all workers along the qc inspecting staff to keep their keen eyes in the line as mentioned above in the following section which leads ultimately to Rmg products as well as to the satisfaction of our valued clients.

It is needless to say how important is the selection of the raw materials in an item , as, the consequences are untold and to take in consideration only the component price is immediately synonymous with ‘no quality’. Sometimes, at the time of the selection the difference is not perceptible, but there is no doubt about it, the outcomes are immediate when the item is used |
||||||||
|
||||||||
|
||||||||
|
||||||||
|
||||||||
The reasons of all these defects which are imperceptible ‘at touch’ is often the canceling of such or such working in the finishing process. |

In selecting the yarn, the following points are to be noted : |
||||||||
|
||||||||
Untwist, then draw the fibers 1 by 1 |

After unknotting, check on a paper the irregularities in the yarn. The slubs are synonymous with qualitative problem at knitting. Besides above following points are to be noted :

A lab test to check the degradation at washing is required. The main cause of degradation is due to the temperature and the imperious respect of passage and pressure time. |

Quality controllers are often given the responsibility to inspect the garments which is the last step of the total systems. Major problems can be Eli mined if the proper inspection can be provided at the stage of knitting, dyeing and finishing. As such, below we are giving a list of defects usually found in the stages as mentioned above. Before this list, it is needed to know that in apparels sector the defects fall into two type as defined below.
|
||||||||
|
||||||||
|
||||||||
![]() |
||||||||
Barre |
Caused by mixing yarn on feed into machine. Fabric will appear to have horizontal streaks. This is major defects. |
|||||||
Birdseye |
Caused by unintentional tucking from malfunctioning needle. usually two distorted stitches occur side by side. |
|||||||
Broken Color Pattern |
Usually caused by colored yarn out of place on frame. |
|||||||
Drop Stitches |
Results from malfunctioning needle or jack. Will appear as holes or missing stitches. |
|||||||
End Out |
Results from knitting machine continuing to run with missing end. |
|||||||
Hole |
Caused by broken needle. |
|||||||
Missing Yarn |
Caused by one end of yarn missing from feed and machine continue to run. |
|||||||
Mixed Yarn |
Results from wrong fiber or wrong size of yarn. Fabric could appear as thick end or different color if fibers have different affinity for dye. |
|||||||
Needle Line |
Caused by bent needle forming distorted stitches which is usually a vertical line. |
|||||||
Press – Off |
Results when all or some of the needles fail to function and fabric either falls off the machine or design is completely disrupted or destroyed. |
|||||||
Slub |
Usually caused by a thick or heavy place in yarn or by lint getting into yarn feeds. |
|||||||
Straying End |
Caused when an end of yarn breaks and the loose end strays and is knit irregularly into another area. |
|||||||
![]() |
||||||||
Askewed Or Bias |
Where courses are not square with wale lines on knit. maximum allowable limit of biasness is 6%. |
|||||||
Bowing |
Caused by filling yarn lie in an arc across fabric width. It become critical on stripes or pattern not as critical on solid color fabric. |
|||||||
Crease Mark |
Appears where creases are caused by fabric folds in the finishing process. On napped fabric, final pressing may not be able to restore fabric or original condition. Often discoloration is a problem. |
|||||||
Crease Streak |
Results from creased tubular fabric passing through squeeze rollers. |
|||||||
Water spots |
Usually caused by wet fabric being allowed to remain too long before drying; color migrates leaving blotchy spot. |
|||||||
Uneven Dyeing |
One of the major reason is rapid addition of dyes and chemicals and occurs due to controlling the time, rate and amount of addition taking place. | |||||||
Uneven Shade |
In a same batch uneven shade may occur if possible same length is not provided in each chamber. |
|||||||
Batch To Batch Shade |
This problem arises if the fabric has not the same affinity to dyestuff, same liquor ratio is not used, same brand of dyestuff is not used, if the programmed of the machine running is changed from batch to batch. |
|||||||
Dye Spot |
These are most often caused by if not correctly mixing and thoroughly dissolving the dyestuff in the right amount of water. |
|||||||
Cockling |
Cockling or dimpling of the fabric surface generally occurs due to smaller diameter of nozzle which increase the speed of the fabric and as well as low liquor ratio. |
|||||||
Running Marks |
Running marks are frequently related to the materials and fabric construction and are caused by poor opening of the fabric rope. |
|||||||
Crack Marks |
This can be result of incorrect process procedures. |
|||||||
Hammer Finish |
Usually found on surface sensitive articles e.g. Plush and uncut pile fabrics. |
|||||||
Crush Marks |
Occurs when running with a higher fabric speed. |
|||||||
Elephant Skin Or Orange Peel Effect |
Often found on woven and warp knitted fabrics which have stopped running during the cooling stage. Materials itself as irregular shaped creases over the fabric surface. |
|||||||
Color Out |
The results of color running low in reservoir on printing machine. |
|||||||
Color Smear |
The result of color being smear during printing. |
|||||||
Mottled |
Color applied unevenly during printing. |
|||||||
Pin Holes |
Holes along selvage caused by pins holding fabric while it processes through the tender frame. |
|||||||
Scrimp |
The result of fabric being folded or creased when passing through print machine. There will be area not printed. |
|||||||
Selvage Torn |
Usually caused by excessive tension while processing through tender frames. |
|||||||

It is nevertheless to say that the garments floor is the final stage of the apparels making. So all other quality measure which are taken before garments floor is just a rehearsal. And in all respect the garments floor is the final stage for the apparels to be produced. Hence this phase covers the all previous measures of quality inspection as double or cross check along with other quality inspections which are limited in this unit. Below we are out lining the defects usually to be inspected section wise.
