Shrinkage measurement tester

Shrinkage measurement tester is the process in which a fabric becomes smaller than its original size, usually through the process of laundry, especially when applying heat. Shrinkage means dimensional change of knit fabric after certain agencies applied on it. It may be occurred when it is washed and dried or ironed. It may be occurred when it is laundered. The main issue for finishing and knitting

How to calculate the shrinkage?

  • The remember is that for every 1/8″ the lines shrink, this equals one percent in shrinkage.
  • Before wash, the lines measured 12.5” so if the fabric measures 12 3/8″ after wash, the difference is 1/8” or 1%  shrinkage calculated.
  • As example- .125/12.5=0.01 x 100 = 1%

What is garments fitting?

  • Basically the customer’s /wearers’ comfort ability will require on the wearing apparels.
  • Better appearance will be the second requirement of the well fitted garment.
  • Different type of fitting problem and its solution
  • We find deferent type of fitting problem when we wear garment on dummy or human body. Some common problem and its solution given on next slides

Shrinkage procedure

  • shrinkage s/b 10% for cotton & 100% for denim & elastin fabric
  • Shrinkage fabric s/b length 70 cm and width 70 cm.
  • write roll no, yards, style name, order no on shrinkage fabric.
  • four side mark s/b distance 50 cm by pen or sewing track.
  • out put side s/b over lock.
  • wash
  • Shrinkage check.
  • Shrinkage report.shrinkage-before-and-after

Documents need to be checked during factory evaluation

  • Fabric / yarn / skin inspection report.
  • Trim / accessories inspection report

Elastomeric Silicone Micro-emulsion for Shrinkage

Auto  is a finishing agent based on elastomeric silicone micro-emulsion stable to shearing forces. It imparts a particularly soft handle and elasticity to a wide range of fabrics.
It can be applied by padding and exhaustion.
The high stability to shearing allows its use on Jet or Overflow machines. Nevertheless, we recommend to perform preliminary trials.
Aqueous dispersions are very stable and the low polarity allows its use with a wide range of finishing agents like fixing agents, electrolytes and resins. It permits to obtain good whiteness without risk for lustre of hue of optical brighteners.

Ionic activity

Yellow hazy liquid

Non ionic

•    Gives a particularly soft and smooth handle
•    Imparts elasticity and a quick shrinkage to hosiery goods
•    Confers good sewing properties, mainly on synthetic blends
•    Can be used as brushing lubricant for fleece fabric
•    Enhances crease resistant properties of finished garments
•    Can be applied on yarns as knitting and winding lubricant
•    Can be used for all types of fibres including natural/synthetic blends and some uncommon fibres like mohair and silk
•    Is compatible with fixing agents like Croscolor FIX-DRS, glyoxal and resin systems
•    Can be applied by padding or exhaust methods
•    It behaves well to shearing

•    By exhaustion

It is recommended to work in slight acid conditions to improve the product build-up. Optimum pH is between 5.5 – 6.5 but an adequate exhaustion is achieved in more neutral medium.
A good stirring is essential to obtain a good absorption and an even repartition.
The level of product to apply depends on different factors like the type of the fibre and spinning (ring or Open-end). In the Open-end system, a higher quantity is needed. A level of
2 – 3 % is recommended to obtain softness with lubricating characteristics and good sewing properties.
It is preferable to dilute Auto  with water before addition to winch and other long liquor ratio machines.
A treatment at 40 – 50°C will give a regular exhaustion after 20 minutes.


Avoid direct contact of Auto  with steam.

To avoid silicone stains, it is recommended to heat the bath at a temperature between
40 – 50°C. Then, add Auto . This temperature must not be modified during the exhaustion of Auto .

•    By padding

We recommend a concentration of 20 – 30 g/l of Auto  for wet on wet application with a good exchange of liquor.
Stable mixtures with crease resistant resins can be made, but it is nevertheless advised to make some lab trial to check the compatibility.

Fabrics can be dried by usual way. It is not necessary to polymerise at high temperature.

Good hygienic and industrial practices should be followed and, when employed as recommended, Auto  will not present any hazard.  However, prolonged skin contact with the neat product should be avoided and any splashes on the skin should be washed off with water.
