Evaluation of impact on hand of terry towels by different treatments

Case 1: A client consigned project on the impact of detergent type

  • 6 (or repeats) terry towels;
  • Before washing, Water washing only, with 6 detergents;
  • Results obtained using PhabrOmeter.

Table below shows the tested fabric attributes after 8 different “treatments”

Comments:

  • The new towel without any washing is the softest;
  • Water-only washing negatively impacts fabric Stiffness and Softness;
  • Detergent washing causes more deterioration in fabric Stiffness and Softness;
  • Fabric Smoothness not impacted as severely.

Using a new towel as the reference, the table below shows the RHV tested after 8 different “treatments”


the OMO detergent has the best overall performance among all.


Commercial Softener Products Comparison (Show Details...)

6 samples of terry towel were washed by the same detergent and after one washing each sample was applied different softener with the same amount.

Relative Hand Value

*No Softener Used fabric was set as the reference fabric. Overall performance rank of each softener product on a base of terry towel fabric:

Comments: the Magic Amah softener has the best overall performance among all.

Attributes

Comments:

  • The new fabric without any washing is always the softest;
  • After detergent washing, if fabric without applying fabric softener, the fabric will be in the worst stiffness state.
  • The Comfort softener is the top one among all to make fabric softer after washing;

Additional Case on Laundry Softener (Show Details...)

A study published by TU Jili and LIU Jinqiang, Journal of Textile Research, 2013

  • 6 terry towels treated by 3 different softeners each at 2 concentrations;
  • Results obtained via subjective panel and using PhabrOmeter.

Conclusion

“ The results showed that PhabrOmeter not only provides a convenient and efficient way to test fabric hand,including stiffness, softness,smoothness,draping value and relative hand value,but also reveals the effect of different softeners on fabric hand,and the difference between different finish concentrations. If sequencing the samples by softness degree,the order was consistent with that by the subjective evaluation."

PhabrOmeter® Technologies

Human sensory evaluation by definition should be the ultimate judge for hand evaluation. However the following problems render it highly limited for industrial use.


  • human subjectivity;
  • culture, market, product variations
  • fatigue and sense shifting
  • communication of the descriptors
  • training panelists

For instrument to replace human sensory evaluations, sensory evaluation has to be used as the validation, especially in establishing standard on instrumental approach.

Applications With PhabrOmeter®
  • Performance validation of new products - by finger printing and comparing the new and old products;

  • Quality control - by finger printing and then comparing with the standard product;

  • Imitating a given product - by finger printing and comparing with the given sample.
