Fabric Spirality tester is a equipment for dimensional distortion in circular plain knitted fabrics. This In House Test Method describes the method of test in order to determine the spirality test method which occurs in a material resulting from laundering procedures. We sale textile machine and garment erp.
The correct number of test specimens are to be prepared and tested as specified within this test method in order to achieve a performance assessment of the product/fabric as described within the scope. Wash garments in accordance with relevant cycle of. If a garment is not available make a bag by cutting 2 samples of fabric, place one on top of the other and sew together on three sides leaving one side open. Ensure the open end is perpendicular to the wale direction. Wash as above.
SCOPE
To determine whether weft knitted garments will twist or distort after being subjected to the relevant washing cycle. This test can be carried out on both fabric and garment.
The test specimens are to be conditioned in the standard atmosphere of 65% Relative Humidity (RH) +/- 2% and 20°C +/- 2°C for a minimum of 4 hours. Preparation of Test Specimens/Materials
Fabric Spirality
Fold the fabric along a Wale line.
Place the marking template on the fabric parallel to the wales and drawn round.
Cut out the double thickness specimen accurately g the knitted wale lines and cut at right angles to these to produce a “bag” square.
Note: The second cuts are not necessarily parallel to the knitted courses.
Sew the two pieces of fabric together to form an open ended bag i.e. similar to a garment. Overlock the single edges of the fabric to prevent unravelling.
Garment:
Test the garment in its finished state.
Record whether any spirality test method is present in the garment prior to washing.
Measure original length and width dimensions.
Note: It is recommended that garments that already exhibit Spirality are not tested because deceptive results will be produced.
Test Procedure
Carry out Washing/Drying procedure as agreed, or specified
Results of Spirality Test Method
After conditioning, lay the specimen on a flat smooth surface so that the natural fold in the washed specimen is flat and free from wrinkles.
Measure the distance “d” to nearest 1mm from the natural dried fold of the fabric square to the inner edge of the seam (see diagram). Repeat on the other edge by gently lifting back the opposite edge to the seam.
On garments these measurements are made at the hem.
Measure the length and width dimensions in order to determine the dimensional change.

Where
L = Length of test Specimen (Fabric)
Or = Underarm to hem (Garment) (After Washing).
Effect of Yarn Twist On Spirality of A Fabric.
Finished fabric spirality may vary depending upon yarn twist.
Generally high twisted yarn may cause high spiraled of fabric and vise versa.
We know that,
TPI=TM*(Yarn Count) 1/2
Say for example 30 count yarn:
TPI= 3.5*(30)1/2
= 19.17
For Knit fabric yarn Lowest TM is 3.5 and the Highest TM is 3.7
For Viscose yarn TM is 3.5 because viscose is long staple fiber (near about 38 mm long, where as cotton is near about 28.5 mm long)
For woven fabric yarn, TM is given to 4.5 because woven fabric yarn needs more strength.

Operation Procedure of Stente Machine
Operation Staff for stente machine
Operation stuffs of Finishing Process includes:
Manager
Textile Technologist / Production Executive
Production Co-ordinator
Operator
Assistant Operator for stente machine
Checklist Before Production
Operator must check the following items before finishing, re-finishing, heat setting and stretching process in Stenter machine process:
Machine parameters are set according to program.
Required manpower is available for feed side and delivery side.
Required chemicals are available.
Batch for Feed side is set.
Lead cloth is guided up through passage point to operator station.
Operation Procedure for 100% Cotton Fabric (Soft Finish)
Calculation of Solution Amount
Production officer or shift in-charge will provide the recipe with the process flow. The finishing procedure begins with the calculation of solution amount for a particular batch. The formula is as follows :
Solution Amount = Total Weight of Fabric ´ Pick-up Percentage (%) + Trough Content + 3% Wastage.
Suppose, we have 500 kgs of fabric, which are to be finished, and for that we need to prepare the solution.
(where 80% is the average pick up of knit fabric, and 50 litre is the trough content of machine trough).
Operation Procedure
Chemicals are measured using the electronic balance and taken in buckets separately. Chemicals are diluted with hot or normal water based on the references of the chemical literature provided by the chemical company.
Mixing tank is filled up with 50% of water to the required solution level and then chemicals are poured separately into the tank through a piece of filter cloth. Then water is added to get the target solution.
Chemicals are stirred for five to seven minutes by the electrical mixer impeller in the mixing tank and then send to the machine through. Then operator will run 1-meter fabric as a trial run to check the parameter(s), softness and hardness, shade match, etc. which is required by the customer. A small piece of fabric from that trial portion is given to the shift in-charge to check the parameter(s).
If the trial fabric matches with the customer-approved sample then production officer decides to go for the bulk production and operators starts the machine for production.
For the bulk production chemicals solution is prepared using the formula mentioned above and poured into the chemical trough.
The capacity of each tank is 400 litre.
Product Quality Check
Shade Check: During the processing of bulk production of any batch, operator checks the shade in the Stenter machine process. If any deviation is detected he informs the responsible shift officer who takes the necessary action to overcome the problem. If the officer fails to rectify the problem he informs the department head who finally gives the decision.
Fault Check in Stenter Machine Process: The operator checks for Knitting faults (i.e. double yarn, yarn contamination, fly yarn, etc.), Spinning faults (i.e. thick & thin yarn, barre mark, etc.) and other faults (i.e. dye resist mark, band line, chemicals spots, torn and hole, variation of shade, fabric structure, etc.) during the process.
In case minor faults occur within the half rolls of fabric (while running about 20-25 rolls of fabric) which is not resulted from previous process and also not recorded on the batch card the necessary action(s) to be taken is as follows :
Check the feed side to make sure that these faults didn’t occur from the previous process.
Stop the machine to identify whether these faults are occurring due to machine faults (i.e. from padder, chain bar, air duct, etc.) or the faults are due to the chemicals (check cleanliness, setting of machine parameter(s) and chemical composition).
If any spot on the fabric, which is not resulted from the previous process, is detected during processing, it indicates that the sequence of chemical pouring in the mixing tank is not correct which resulted in bad chemical reaction. If this happens, the process should be immediately stopped and responsible officer should be informed for investigation.
Width Check in Stenter Machine Process: Measure fabric width by using a measuring tape and compare it with the required width that is mentioned by production officer on the batch card or program.
Design, Fabric Bow and Slant Check in Stenter Machine Process: Check the design, bowing and slanting of fabric at the delivery side. Adjust the machine by straightening the courses line of the fabric for checking the bowing and slanting.
Pin Setting Check in Stenter Machine Process: Check at the delivery side whether the selvage of fabric is detached from pin and for minimum of 0.5″ each side pinning wastage is maintained, if any abnormality found, immediately inform the head operator.
Q.C. Sample Tests
1-meter sample is cut from each batch during processing and are sent to the Q.C. Department for lab testing. In Q.C laboratory, these samples are tested according to the quality requirement of the customer such as dimensional stability test, washing fastness, water fastness, light fastness, pilling test, crocking (dry & wet) etc.
After all necessary testing, the results are recorded on the Q.C. Sheet. Refer to Off Line QC Test Specification (Document No. 81-101) for details.

Textile stenter machine parts are very important to complete the whole stente process. The steps process using stenter frame and relax dryer and compactor. The damp fabric runs through the relax dryer (no pins) at a fast speed because the fabric has only 30% water content. Fabric comes out dry at 68-70″. The Maintenance Department performs the preventive maintenance task as per the schedule. Refer to Maintenance Specification for details.
Stenter Frame
Stenter frame – 5 chamber (could be more or less but settings below would change) run at 230-260 degrees fahrenheit (normally running at 330-350 degrees f) 45-50 yards/min. The knit fabric is dyed in tubular form, then slit. The fabric goes into the stenter frame wet at 60-63″. The fabric is put on pins and needs to be stretched by 10-15 inches. This means that the wet fabric is put on the pins and then opened up by 10-15 inches into the stenter frame. If the fabric is not pulled open enough, it will not get the torque out of the fabric. Very important: fabric should exit stenter frame with 30% water – still damp
Run at 280-300 degree fahrenheit (normally running at 350 degrees f)
45-50 yards/min
**test**before the compactor, the fabric can be tested for torque and shrinkage to see if there are any problems. We test for torque by making 3 boxes across the fabric to see what the average is (see attached picture). This test is important. The torque at this point should be very low, under 3%. If it is not, the fabric wasn’t pulled open enough on entry to the shrink dryer or there is a knitting issue. **the length shrinkage should be 6-7% at this point. If length shrinkage is higher than this, the fabric wasn’t pulled open enough. If length shrinkage is greater than 6-7%, the compactor won’t be able to achieve the target shrinkage of 4×4% (5×5 is the specification). Very important: the fabric should be off-grain (not be strait) coming out of the stenter.
Compactor
The fabric then goes to the open width compactor. The fabric should be run natural through the compactor do not try to make the grain strait. The finished fabric should be off grain by about 8 inches out of the compator. The temperature on the compaction machine needs to be 104-115c (220-240 f) to create enough heat. Fabric is then rolled up.
