Estimating the term…
Provided is an adaptive strap for brassieres having at least one adaptive material layer (10) having a first strength modulus x during static loading and a second strength modulus of at least 2× during dynamic loading of at least approximately 3 Hz oscillation. The adaptive layer (10) is sandwiched between two or more elastic fabric layers (20). The adaptive strap is extendable up to 100% of its initial length during low wearer activity but is extendable not more than 50% during vigorous wearer activity, providing support during exercise and comfort during daily use. In one aspect the adaptive material is a reaction product formed by reacting a silanol terminated polydimethylsiloxane, polymer matrix, boric acid and optional fillers. The adaptive material (10) is cured in situ within the elastic fabric layers (20).
An adaptive strap for brassieres comprising:
An adaptive strap for brassiere, wherein the adaptive strap has a tensile strength of more than 4 MPa at 2.0 Hz after 960 circles and a tensile strength no less than 1 MPa at static status under the strain of 10% of its initial length.
