Description

BRIEF DESCRIPTION OF THE FIGURES

[0016] FIGS. 1A-1C are diagrams comparing typical every course panty hose construction (FIG. 1A), typical alternate course panty hose construction (FIG. 1B) and a modified every course style of the present invention comprising spandex covered with polyamide and bare spandex plated with polyamide in every other course (FIG. 1C).

DETAILED DESCRIPTION OF THE INVENTION

[0017] Provided by this disclosure are fabrics prepared from a modified every course style with courses of spandex covered with rigid yarn and bare spandex plated with rigid yarn, elastified knitted garments prepared from these fabrics and methods for production of elastified knitted garments at lower cost and with improved comfort, increased gloss, and/or in some embodiments increased run resistance as compared to fabrics prepared from traditional every course and/or alternative course styles.

[0018] By the term spandex as used herein it is also meant to be inclusive of elastane and/or lycra.

[0019] By traditional every course style by which improvement in gloss and/or run resistance and/or to which cost is compared for purposes of the present disclosure, it is meant a fabric knit from spandex covered with polyamide in every course.

[0020] By traditional alternate course style by which improvement in comfort and/or run resistance is compared for purposes of the present disclosure, it is meant a fabric knit from spandex covered with polyamide or bare spandex plated with polyamide and polyamide only in every other course.

[0021] By plating or plated for purposes of the present disclosure, is it meant that the rigid yarn and the bare spandex yarn are kept in a parallel, side-by-side relation throughout the knit, with the relation between the two yarns controlled such that the spandex material is always kept on one side of the rigid yarn.

[0022] The fabrics of this disclosure are prepared from a modified every course style as all courses are elastified and therefore technically an ECPH with all its benefits in terms of comfort and stretch.

[0023] One of the elastified courses of the fabrics of this disclosure comprises a spandex covered with rigid yarn. The covered spandex can be single covered, double covered or air jet covered. Important advantages of using covered yarn in the fabrics of this disclosure include, but are not limited to, a more natural soft touch as compared with the plastic, slippery touch of spandex as spandex is covered and not directly exposed to the skin and a reduction in the fragility as compared to bare spandex.

[0024] The other elastified course of the fabrics of this disclosure comprises bare spandex plated with rigid yarn. Any spandex suitable for the fabrics of this disclosure can be used in one nonlimiting embodiment, the spandex is fusible.

[0025] Any rigid yarn can be used in the present invention. Nonlimiting examples may comprise polyamide, polyester or polypropylene. In one nonlimiting embodiment, the rigid yarn is a polyamide. Any polyamide can be used and, as will be understood by the skilled artisan upon reading this disclosure, selection will depend upon desired characteristics including, but not limited to, brightness, bulk, uniformity, and gloss of the resulting fabric.

[0026] Inclusion of the non covered, still elastified course in the fabrics of this disclosure allows rigid yarn such as a polyamide to shine as there are no turns to inhibit the shine. Accordingly, the fabrics of this disclosure are higher in gloss as compared to typical ECPH. Further, the negatives of the use of bare spandex in a portion of the courses are mitigated by the other portion of the course which are covered thereby providing for run resistant garments with shine.

[0027] Various repeating patterns of the two elastified courses can be used in the fabrics of this disclosure and selection may depend upon the garment in which the fabric is being used and/or the knitting pattern.

[0028] For example, FIG. 1C depicts a repeating pattern comprising a course of spandex covered with rigid yarn followed by a course of bare spandex plated with rigid yarn.

[0029] In an alternative nonlimiting embodiment, the fabric can be knit in a repeating pattern comprising a single course of spandex covered with rigid yarn followed by two or more courses of bare spandex plated with rigid yarn.

[0030] In an alternative nonlimiting embodiment, the fabric can be knit in a repeating pattern comprising two or more courses of spandex covered with rigid yarn followed by a single course of bare spandex plated with rigid yarn.

[0031] In hosiery, typically the number of feeds of distinct courses are 4 and these can all be the same or different.

[0032] In seamless knitting, however, there are typically 8 feeds while in circular knitting 32 or more feeds are used.

[0033] As will be understood by the skilled artisan upon reading this disclosure, any of these patterns as well as alternative patterns can be used in accordance with the present invention and the invention is in no way limited to any particular repeating pattern or number of courses of spandex covered with rigid yarn followed by courses of bare spandex plated with rigid yarn.

[0034] In one nonlimiting embodiment, fabric is prepared by weft knitting.

[0035] In one nonlimiting embodiment, other yarns are added to the feeds to, for example, make the fabric heavier or to introduce design, pattern and/or color to the fabric.

[0036] This disclosure also provides garment, at least a portion of which is prepared from these fabrics having a modified every course style comprising courses of spandex covered with rigid yarn and courses of bare spandex plated with rigid yarn. In one nonlimiting embodiment, the garment is a sheer garment. In one nonlimiting embodiment, the garment has an 8 to 20-25 denier appearance. In one nonlimiting embodiment, the garment is hosiery or intimate apparel. In one nonlimiting embodiment for hosiery, the fabric of the present invention may be used in the leg portion which the panty or other sections may comprises fabrics with typical constructions. In an alternative nonlimiting embodiment, the garment is non-sheer.

[0037] Further provided by this disclosure are methods for improving comfort, increasing gloss, and/or increasing run resistance of an elastified knitted garment as well as methods for lowering cost of an elastified knitted garment. These methods comprise preparing the garment from at least a portion of fabric comprising courses of spandex covered with rigid yarn and courses of bare spandex plated with rigid yarn.

[0038] All patents, patent applications, test procedures, priority documents, articles, blieations, manuals, and other documents cited herein are fully incorporated by reference to the extent such disclosure is not inconsistent with this invention and for all jurisdictions in which such incorporation is permitted.

[0039] The following Example demonstrates the present invention and its capability for use. The invention is capable of other and different embodiments, and its several details are capable of modifications in various apparent respects, without departing from the scope and spirit of the present invention. Accordingly, the Example is to be regarded as illustrative in nature and nonlimiting.

Example

[0040] An elastified knitted garment was prepared by typical ECPH wherein feed, 1, 2, 3 and 4 were 20 dtex fusible spandex (LYCRA fiber 777F) single covered with polyamide 6,6 flat, bright 17 dtex 3 fil.

[0041] An elastified knitted garment was prepared using ECPH of the present invention wherein feed 1 and 3 were 20 dtex fusible spandex (LYCRA fiber 777F) single covered with PA 6,6 flat, bright 17 dtex 3 fil and feed 2 and 4 were 20 dtex fusible spandex (LYCRA fiber 777F) bare, plated with PA 6,6 flat, bright.

[0042] Results of testing of these elastified knitted garments are depicted in Table 1.
