Knit Fabrics Evaluation

Knit fabrics made of superfine Merino wool

From Client D, a set of knit fabrics made of superfine Merino wool.

This is an overall comparison of performance between all fabrics in relative terms. In this case, the key again is to select a sample as the Reference; it can be one of the fabrics to be tested or any pre-designated fabric. Setting the Sample 6 for this group as the reference origin (0) as from the client, column 1 (RHV) is the fabric ranking relative to the references.

Conclusion: In overall performance among all the fabrics of lightweight, Sample #10 most different from #6. All the others are in between as shown.

The corresponding fingerprint for the samples:

The table shows the Softness values

Conclusion: Sample #6 is the softest, and #10 the least soft among the fabrics. All the others are in between.

PhabrOmeter® can also test the fabric wrinkle recovery as listed below.

Physical Meanings of the 8 principal components

The fabric hand attributes vi are mathematically determined. However, to make the system easier to accept, we still use the common sensory terms such as stiffness, smoothness and softness.
It is proved that there are total 8 such attributes v1, v2, v3 … v8. As the first step, we only identify the first and also the most important 3, i.e., v1=Stiffness, v2 = Smoothness and v3 = Softness, in that order.
For more comprehensive comparison, we use all 8 components to calculate the Relative Hand Value, and to construct the Fingerprint for the fabrics.

Testing Repeatability

As show in tables below that the repeatability of PhabrOmeter® in measuring the fabrics is highly consistent.
