1、PROCESSED FABRIC INSPECTION UNDER 4POINT SYSTEMAll fabric inspections conducted by Textile Links and Controls is according to the four-point fabric inspection system. The four-point system derives its name from the basic grading rule that a maximum of four penalty points can be assessed for any sing
2、le defect and that no linear meter can be assigned more than four points regardless of the number of defects within that piece.PENALTY POINT EVALUATION:Defects in both warp / fill directions will be assigned points under the following criteria.Defect RangePoints EvaluationUp to 3 inches1 Point 3 inc
3、hes 6 inches 9 inches 4 PointsWHAT IS A DEFECT?The length of the defect is used to determine the penalty points. Only major defects are considered. A major defect is any defect, if found on a finished product, would classify the product as a B-grade.Any defect of a continuous nature shall be assigne
4、d four points for each meter in which it occurs.Severe defects are assigned the maximum four points for each meter in which they occur. Example: Regardless of size, a hole would be penalized four points.Continuing conditions such as barre, side center side shading, roll to roll shading, narrow or ir
5、regular width, creasing, uneven finish shall be counted four points for every meter within the shipment that is found to contain these conditions, provided that the article that is to be made from this fabric is classified B-grade due to this fault.The maximum penalty for any one-meter shall not be
6、more than four points.A minor defect is any defect that does not classify the product as B-grade because of either severity or location. When inspecting fabric before cutting, it is necessary to rate questionable defects as major, since the inspector will not know where the defect may occur on the i
7、tem.Running Defects:Any major defect found to repeat and / or run in a continuous manner will constitute a running defect. All major running defects must be assigned four penalty points to every meter in the roll where it occurs.Full Width Defects:A full width major defect would cause that meter of
8、fabric to be assigned four penalty points.Fabric Width:Fabric width will be checked minimum of three times during the inspection of a roll (beginning, middle and end of the roll).Rolls having width less than the specified are potential problems. In such cases width deviation of more than 1% would co
9、nstitute a major fault.Overall, fabric width is measured from out side of the selvage to the outside of the opposite selvage.Roll Length:Rolls having meters less than that stated on the packing are a problem. Any roll having more than 1% lesser fabric than that specified is rejected.The entire shipm
10、ent shall be rejected if the total measured meters in the sample audit are more than 1% short that what is declared on the packing.Splices:Rolls can be composed of several spliced parts. No roll shall be accepted that contains a splice less than twenty five ( 25 ) meters in length unless otherwise e
11、xpressly accepted. Ensure that the 95% of the shipment contains 100 meter plus fabric length if the fabric is being used for made - ups. In case of piece goods, the fabric length and the number of splices / roll are strictly followed as per the requirement of the customer.Bow & Skew:No roll shall be
12、 accepted as first quality that exhibit bow or skew more than:Fabric WidthMaximum Bow or SkewDesign Print/dyesDeviationUp to 45 inches 2.0%2.0%60 inches2.0%2.0%90 inches and above2.0%2.0%The above is subject to change if buyer requires a tighter tolerance / nature of design / end use of the fabric.T
13、olerance for bowed condition not affecting the full width will be fractionalized part of the maximums as stated above according to the area affected by the bow.Penalty points will not be assigned for fabrics found to have conditions of bowing in excess of the above stated tolerances but shall be not
14、ed in the inspection report. And if any fabric exhibits bow or skew where its end use becomes doubtful, then that fabric will be rejected. Fabric Odors:No roll shall be accepted that exhibits objectionable odors.Holes:All defects that break the fabric, regardless of size, shall be penalized a maximu
15、m of four points. A hole consists of two or more broken yarns.Common Fabric Faults:Although fabric faults are numerous but some of the common fabric faults are mentioned below:Abrasion Mark: A place in the fabric where the surface has been damaged due to friction or abnormally weakened by any operation through which it has been passed.Bow: When the filling yarns lye in an arc across the width of the fabric.Skew: Distortion in the construction of the fabric i.e. in the yarn that constitute the fabric.Crease: A fabric defect across the fabric width usu
