Difficulties or Challenges inwards automation:
Unlike the large-scale automation in other industries, garment industries are much slower in adopting the engineering science. The major problem hovers about proper treatment of the cloth, due to high flexibility.

One of the major areas of enquiry for several groups is related to the automation inwards fabric handling. The major ingredient of wear is the fabric, too inward many operations they involve to live moved from an performance or placed for a novel functioning. For moving the fabrics, they ask to be held past an appropriate device in addition to transferred to a movable constituent together with and so replaced for another functioning. The choice as well as design of such devices depend on the textile properties, the operational speed, accuracy required, and the position of the points on the textile for which such accuracy is required. The fabric may call for to live gripped together with transferred equally a unmarried factor placed on a surface (e.g., table) or from a mass of other fabrics. For gripping a unmarried factor, a number of approaches tin live taken as discussed in Table.

Some of the commercial devices based on the belongings methods as described in Table are discussed in the following department:

  • Clupicker uses the pinching method to hold the fabrics, which is like to the human being fingers picking up the fabric. When a Clupicker is programmed to grip ane component, it will live hard to travelling bag the garment assemblies.
  • Polytex is based on the method of using pins or needles to pick upwards single fabric element. As these devices are prepared alongside high precision, they are slightly expensive.
  • Littlewood is besides based on the method of using needles, which is a variation of the needle principle used to furnish reliability inwards ply selection upward.
  • Walton device is based on the combination of air foil, needle, in addition to suction for picking upwardly “oneply exclusively.”

Although commercial equipment has been designed using the methods in Table, they are not real successful in cloth belongings together with transferring because of the following reasons:

  • There is lack of primal engineering approach,
  • There is lack of quantitative textile information, too
  • The master copy equipment manufacturers (OEMs) do non perform dedicated enquiry to solve the problems.

The detection of fabric before gripping tin can be accomplished by the application of dissimilar sensing techniques such every bit:

  • Optical: H5N1 light source or infrared ray can live used.
  • Mechanical sensing: Influenza A virus subtype H5N1 mechanical sensor can live used.
  • Airflow: Measure pressure level drib of airflow.

All the fabrics used for dress purposes are flexible materials, and the handling is influenced by textile stiffness. The other influencing fabric properties during textile handling are the friction, which is characterized by coefficient of friction, together with longitudinal extension (EM). All these 3 properties (stiffness, friction, and EM) play of import function inwards textile treatment. The depression values of textile stiffness too friction as well as high EM make the automatic handling rather a difficult job. Because of high variability of these 3 factors amongst dissimilar fabrics, it is difficult to blueprint automated equipment that can grip all types of fabrics.

Furthermore, these cloth properties modify depending on the relative humidity too temperature of the working room. As the working room atmospheric condition inward many garment industries are non just controlled, the modify inwards fabric properties volition cause difficulty inward material treatment. During automatic placement of cut blueprint pieces for sewing performance past automatic machines, mismatching of patterns tin can pass. Positional errors of 5–10 mm mostly occur during the operations such as laying, grasping, folding, as well as sweeping.

Fabrics are flexible cloth every bit they undergo pregnant out-of-aeroplane bending alongside the application of small forces. The limpness of the fabric due to depression stiffness makes it hard for automatic treatment. Automatic handing is real slowly inward automotive manufacture where stiff components are handled by robotic arms. Considering the developments relating to textile handling in automotive industry, one would observe that almost no progress has been achieved inwards garment manufacturing. The inherent nature of the material for automatic treatment has made the universal application of automation a hard chore.

The traditional process of manually joining 2 fabric components by sewing involves: (1) gripping the cloth components, (2) aligning or matching them at the reference bespeak or notch, (iii) stitching for the necessary length, in addition to (four) removing the stitched ingredient together with placing them in a place to be picked upwards past the side by side operator. Hence, patch designing automatic robots for fabric handling as well as sewing of garments, these operations should be kept in heed. The automatic device should be able to travelling bag and feed the fabric factor(s) to a sewing auto, tally the reference points, if at that place are two or more components, grade the seam, manipulate the components about the needle, run up them together, too take them as the stitching has been finished.

While designing the automatic robots, it is important to view dimensions of the components to live joined together with their range, the physical features of the components (such equally stiffness, surface roughness, too porosity), in addition to the total of stitching needed. There are unlike ways of moving the material from ane to the other place such equally choice as well as deport, sliding, rolling, conveying, destacking, alignment, in addition to distortion.

The automation of sewing at high speed tin can Pb to excessive needle heating, which tin upshot in improper sewing in addition to faults in the garment. The detection too remedial action is essential to produce lineament garments. To resolve this job together with facilitate high-speed automatic sewing, researchers at the Georgia Institute of Technology (GIT) have developed a device that can place excessive needle heating together with indicate to the operator. The device is based on the function of certain audio frequencies whose amplitudes increment when sewing needles become worn. In the incident of a thread pause or when the needle clothing exceeds a preset degree, the calculator alerts the operator past sending a betoken that turns on a light. Researchers at GIT are also designing devices to discover sewing problems resulting from needles as well as thread earlier they take place. Piezoelectric sensors can live used to monitor the thread crusade during sewing, which post the information into a reckoner too the estimator detects the fault.
