拉架布 LYCRA SHEET
Multiple layers are needed for use in suspension-purpose.
The heavier the loading, the more layers needed.
How much weight ONE sheet of lycra can hold ? There are factors affecting it. We did TWO simple tests at CREST with the spec. below to help give some references to this question:
LYCRA spec.:
6ft length
62-64 inch width
82% Nylon, 18% Spx
~180g/ yard
DISTANCE BETWEEN HANGING POINT:
80cm holding point distance
DIRECTION:
Length of the lycra parallel to the hanging point.
lycra width Vs between hanging point distance affect how much it is stretched.
Lycra has different "tolerance to stretch" in different direction.
Suggestion on a way to hang up Lycras
A suggested way bto tie the knob for hang up Lycras
TEST 1
HEIGHT:
Knot height from ground 135cm
RESULT:
WEIGHT: 34kg.
It still not touch the ground yet, 10cm above the ground.
TEST 2
HEIGHT:
Knot height from ground 200cm
WEIGHT: ~50kg (an Adult)
It still not touch the ground yet.
These data are for REFERENCE ONLY. Each lycra sheets weight/stretch tolerance also affected by the shape of the object, and the type of dye used.
