describe in detail

Term used herein " Spandex (spandex) " is a kind of long filament of manufacturing, and the material that wherein forms long filament is the long-chain synthetic polymer that comprises at least 85% weight block polyurethane.Multiple different Spandex composition can be used for the panty hose (pantyhose) of some aspects, for example the Spandex based on polyethers and copolyether especially.The instantiation of commercially available Spandex yarn comprises with trade name LYCRA 162B, LYCRA 163C, LYCRA 163A, LYCRA 178C, LYCRA 902C and LYCRA 777C (especially can be used for on-run stocking) can derive from INVISTA S. à r.l. of Wichita, those yarns of KS.

In whole description, term " panty hose " and " stocking " are used interchangeably, be intended to comprise the part with circular knitted fabric structure at least and the clothing that comprises trousers part, trousers part is generally from dropping to crotch around waist, but may extend into wearer's upper huckle.

Panty hose can comprise any applicable combination of elastomeric yarn or elastomer yarn and hard yarn.Elastomeric yarn or elastomer yarn can be included in each row or the row that replaces in (other structure can be used for the stocking place of desired pattern).A kind of applicable elastomer yarn is the Spandex that can use exposed or coatedly.Coated can be individual layer coated or double-coating, air-coating, air jet texturing, entwine, cored etc.

The example of hard yarn comprises polyamide yarn, for example nylon 6, nylon 6/6 (PA 66), nylon 10, nylon 12, nylon 6/10, nylon 6/12 and their combination.Hard yarn can be straight or distortion.Panty hose can comprise the yarn of the mixed yarn that is selected from the coated Spandex yarn of polyamide and the coated Spandex yarn of polyamide and polyamide yarn.

During knitting, change with the yarn of cumulative line density (dtex) with by changing and/or increase yarn tension by use, can realize the gradual change compression of trousers.A kind of device of measuring and controlling yarn tension is to derive from BTSR International S.p.A., the permanent tension force Yarn feeder (KTF) of Italy.

Suitable amount Spandex fiber can be with whole yarn weighing scales approximately 10% to approximately 30%, comprises approximately 12% to approximately 26%, and approximately 15% to approximately 22%.

Gradual change compression trousers are selected from single layer structure, complete double-decker and part double-decker.Each these structure is got rid of waistband, unnecessary because grading structure makes it to become.By thering are a series of regions of region (shank join domain) the different compression level that (lumbar region) increases to top from approaching most bottom, provide gradual change compression.In the end-results of clothing, the top of trousers has the compression of highest level.Applicable number of regions can comprise approximately 2 to approximately 10 regions of different compression level, for example approximately 3 to approximately 5 regions.This comprises the region of approximately 3 different compressions.

The zones of different difference of compression can be any applicable amount, makes trousers part remain on wearer's ability of appropriate location with it required comfortableness to be provided, to maintain simultaneously.The compression increasing may be up to approximately 2 times to approximately 20 times in region from bottom to top.According to the overall compression level of trousers, this comprises high to approximately 3 times to approximately 10 times, and high to approximately 4 times to approximately 9 times.

The percentage of each region coil line number depends on required gradual change compression and overall area number.In the time having three regions, bottom section can comprise approximately 10% to approximately 50% of overall coil line number in trousers, and this comprises approximately 15% to approximately 40%, approximately 20% to approximately 30%, and approximately 15% to approximately 25%

Below be described in more detail three kinds of different structures.

double-layer trousers completely:

In this structure, in the whole length of trousers in trousers region knitting bilayer.This bilayer can be by knitting providing in independent layer.Then double-layer trousers also can be folded and be sewed up by knitting individual layer and make.This completes by knitting individual layer, and individual layer increases compression from shank tie point to maximal pressure contracting central point, then reduces compression to top section.Folding this top section, with engagement leg coupling part, makes to produce fold at the approximate maximal pressure point reduction place corresponding to waist.While completing, top section (the approximate waist corresponding to wearer) at trousers has enough compressions to keep clothing, and prevent clothing rolling whereabouts, from bottom, (shank coupling part) increases to the top area (waist) of trousers the compression in trousers district.By the combination that yarn is selected and knitting machine arranges, for example elastomeric yarn tension force and suture length, realizing compression increases.

part is double-deck:

As an alternative, the knitting bilayer in the top in Zhi Ku district, is similar to above about described in complete bilayer.But this double layer area is significantly greater than standard (bilayer) waistband for conventional waistband.Part bilayer can be in trousers overall coil line number approximately 10% to approximately 50%, this comprises approximately 15% to approximately 40%, and approximately 20% to approximately 30%.Equally in this structure, in order to provide enough compression to keep clothing and to prevent that clothing rolling from falling at the top section of trousers, the top area of the compression in trousers district from bottom to trousers increases.By the combination that yarn is selected and knitting machine arranges, for example elastomeric yarn tension force and suture length, realizing compression increases.

individual layer

Another is alternative is individual layer gradual change compression trousers.This is included in trousers bottom (shank join domain) and has the lower gradual change compression trousers that are compressed at top (lumbar region) and have higher compression.This structure comprises the multiple regions that are similar to complete bilayer and part double-layer trousers structure, also avoids needing the conventional waistband arrowband of the higher compression at trousers top () simultaneously.By the combination that yarn is selected and knitting machine arranges, for example elastomeric yarn tension force and suture length, realizing compression increases.

Shank part can comprise the yarn having with the identical danier of yarn (line density) in trousers part, lighter danier or heavier danier.Shank part (left and right) can have and is selected from transparent, half opaque and opaque structure.In order further to improve comfort level and ease the pain during to wear, shank part can comprise respectively leg portion, wherein goes up leg portion and comprises enhancing yarn.

The structure of shank part can be in any kind well known in the art.These comprise from trousers to toe and cover, expose toe, ankle length, knee length or any other Len req for shank part completely.

The features and advantages of the present invention show by following examples more fully, provide these embodiment for explanation, should not be construed as and limit by any way the present invention.
