Fusing Machine for Garments

Fusing machine for garments is very much important to maintain the quality of the products.Fusing press machine for garments is very much important to maintain the quality of the products. The press machine carries out fusing by holding the fabric & the interlining between the conveyor belts while heating. The pieces are then pressed by rollers at the outlet. The required fusing temperature is achieved by bringing the belt into contact with the heating elements

Each day before start of production, the pressure on the left, rihgt and center of the rollers shall be checked by means of the light weight woven fabric strips. One of the strip shall be passed through the T Shirt Heat Press Machine for garments while holding the other and tight. When the end passes out of the press, the strip will be pull to feel the pressure of the rollers.

When we start any order in the sewing floor. We make sure fusing machine parts of the garments. At first we collect the data sheet from the supplier. According to data sheet (like: pressure    time: temperature) we adjust the m/c. After adjusting the m/c we check the m/c (1) thermo paper (2) thermo meter. We check the fusing   m/c by thermo meter two times in a day that means after lunch and before lunch against every order according  to data sheet. 3.bond strength test machine: we doing bond test when test the machine (after lunch before lunch)

Fusing Machine Operating Procedure
  • After the test run, the fabric will be checked for proper fusing by the QC manager. If the proper fusing condition has been achieved, The QC manager will approve the fused part with signature and temperature setting and the process will continue, otherwise adjustments shall be made to temperature and timing to obtain proper fusing. After that, upon approval of the QC manager the fusing shall commence.

Fusing: Fusing is the process of joining interlining with the fabric. The interlining contains adhesive, which melts at a specific temperature (Glue Line Temperature) and Pressure to make bond with the Fabric.

Importance of Fusing: Fusing is one of the most important processes involved in apparel manufacturing which affects the appearance of the garment. It also provides support and strength to the specific parts of the garment.

Parameters for Fusing: There are three parameters involved in the fusing process:

  1. Fusing Temperature
  2. Fusing Pressure
  3. Fusing Time

Initial Procedure: In the Tech Pack, buyer provides the details about the type of interlining to be used and also the quality standards to be maintained.

As per the details mentioned in the Tech Pack, the respective merchandiser communicates with the suppliers for getting the interlining.

The supplier provides the details of the interlining along with Test Report. This Test Report contains the details of the M/C in which the test was done along with the Temperature, Pressure and Time to achieve the Glue Line temperature.

The Technical GM goes through the Test Report along with the details provided in the Tech Pack. He provides the instructions to the Cutting Department to follow during fusing.

Fusing Procedure: The temperature, pressure and time of the Fusing M/C is set as per the instructions received during the Technical Meeting.

Thermo-strip is inserted in the M/C to achieve the Glue Line Temperature (Actual Fusing Temperature). This process is done twice a day; once in the morning 8:10 AM after starting the M/C and once in the afternoon (45 min after lunch).

Once the Glue Line temperature is achieved, Fusing for 10 Pcs (Mock Ups) is done.

2 Pcs are sent to the Lab for testing the Bond strength. This test is done by the Lab In-charge using the following M/C: OHBA SIKI JAPAN.

8 Pcs are sent to the Washing Department, to observe the effects after wash. The after wash Pcs are checked for bubbling, stain marks and strength.

The results from Lab and Washing is sent to the Technical GM. If the results are OK, approval for Bulk Fusing is given. If any deviation is observed, the Technical GM finalizes the correction for the temperature, pressure and time and communicates to the respective GM.

The cutting department follows the instructions provided by the Technical GM to achieve the Buyer Required Standards.

Requirements of Temperature, Pressure and Time for Commonly Used Interlinings:

M/C Type                                            Temperature                Pressure           Time

OLD Machines                                   150 Degrees C                        2 Kg                15 Sec

New M/C (HASHIMA HP900LC)    120 Degrees C                        1.5 Kg             12.5 Sec

Requirements of Temperature and Pressure for KOHLS VT 20SP Interlining:

M/C Type                                            Temperature                Pressure           Time

New M/C (HASHIMA HP900LC)    100 Degrees C                        2.5 Kg             12 Sec

Reports in Fusing Section: Two reports are being made in the Fusing Section:

  1. Fusing M/C Temp & Pressure Checking Report:

This report contains Thermostrip along with Fabric swatch. This report needs to be filled up two times a day (before starting fusing in morning & before starting fusing after lunch).

  1. Fusing M/C Clean Report:

This report is filled up 3 times a day (10:00 AM, 1:00 PM and 4:00 PM).

Fusing test-Bonding

Bond strength – or the sturdiness of the seal between the fusible interlining and the fabric – should be evaluated after fusing, and after washing or dry cleaning, depending on the recommended care of the garment

A basic idea about fusing:

Cuff, Collar, Flap, Epulate, Band

Fabric Description Lining Description Required temperature Required speed/ time Required  presser
100 % Cotton Cotton 160-170 10-12 2-2.5 Kg
100 % Cotton Paper 130-140 10-12 1 Kg
100% Polyester Paper Adjust able in test 10-12 Adjust able in test
100% Polyester Cotton Adjust able in test 10-12 Adjust able in test
68% Cotton,

27% polyester,

5% Elaston

paper 130-140 10-12 1 Kg

Note: – * if lining is thick then it needs to adjust less heat and time.

* If lining is thin then it needs to adjust more heat and time.

 

Fabric Description Lining Description Required temperature Required speed/ time Required  presser
100 % Cotton Cotton 180-185 18-22 8-10 Kg
100% Polyester Cotton Adjust able in test Adjust able in test Adjust able in test
Almost of order at front placket lining is used cotton lining.

Note: – These above information always not correct but this is a basic idea that can follow. After testing according to fabric and lining nature speed, temperature, presser should be set up.
