Abstract
The present invention generally relates to both an apparatus, a test form and a method for evaluating sock-drop. More particularly, the present invention relates to an apparatus able to simulate particular forces exerted by human movements, a test form resembling a human leg as well as a method for testing sock-drop so that properties such as compression and comfort can be balanced.
Claims6
A method for evaluating sock-drop comprising the steps of:
- a) loading a sock onto a test form;
- b) agitating the test form having the sock thereon with a reciprocating motion for a predetermined time along a main axis of the test form;
- and
- c) measuring a sock-drop distance traveled by the sock,
- wherein the test form for measuring sock-drop comprises a conical structure having a first position and a second position, the first position corresponds to an area of a human leg below the ankle and above the foot, and the second position corresponds to an area of a human leg on the calf below the knee.
The method according to claim 2, further comprising the steps of a) observing any occurrence of sock buckling;
- and b) recording the elapsed time from the start of the test until buckling occurred.
A sock testing apparatus, comprising:
- a) a means for agitation, wherein the means for agitation provides a reciprocating motion;
- and
- b) a test form removably attached to said means of agitation,
- wherein the reciprocating motion is along a main axis of the test form, and the reciprocating motion has a higher peak deceleration at a first end of the motion than at a second end of the motion.
