Can be used for the different bodily forms under one size and will not be relaxed after repeatedly dress.
Background technology
Human body contour outline is variable, thus is difficult to the most suitable underwear of someone's selection or accessories.Sometimes due to being applied to human body
Plus unsuitable pressure, inappropriate clothes or accessories also can result in that human body is uncomfortable or even allergy.If wearer thinks
Want if strenuous exercise, this problem will become more serious.For example, traditional socks are generally by elastomer or other synthetic fibers
Or both be mixed.Stocking blank is generally made by for increasing the elastomer or elastic thread of elasticity, so that socks will not be light
Change places and slid from leg.However, the unsuitable pressure that the elastomer/elastic thread is applied to leg first is very uncomfortable
's；Secondly, after long-time is worn, high pressure may cause impression on leg.It has been found that the impression that socks cause
Blood circulation can be hindered, and it is therefore harmful to people's leg.The common underwear of such as underbody generally comprises flexible fiber；Although

Specific embodiment
The invention discloses a kind of new design concept, its feature and wearing comfort for being used to realize clothes but not
Realize high power retentivity.This invention applies relatively low restoring force, therefore causes lower pressure under identical elongation；And
There is certain shape fixability under larger elongation, so that a size is adapted to not consubstantiality in the case of with comfort
Shape.After heat treatment, for example after hot wash or drying machine drying, using the woven weaving of shape memory fiber of the invention
Product can be returned to original dimension, but regardless of its before heat treatment elongation be how many.
The textile being made up of shape memory fiber（Such as underwear and accessories）Its comfort can be improved.This has benefited from shape
Memory fiber has the crystallized ability of temporary shapes, and it causes that the feeling of stress of wearer is reduced.By shape memory fiber system
Into underwear（Such as underclothes）With accessories more than transition temperature, such as body temperature（32~34 DEG C）When become soft and be suitable for
