Definitions

• the present invention relates to fabrics prepared from a modified every course style with courses of spandex covered with rigid yam and bare spandex plated with rigid yam and their use in production of elastified knit garments.
• spandex fiber may be covered with, for example, polyamide, or may be bare, and is knitted in every course as depicted in FIG. 1 A or alternate courses as depicted in FIG. IB.
• Garments such as every course panty hose (ECPH) comprise balanced stitches and normally provides for a higher quality garment. Typically, the spandex is covered. ECPH provides a balanced smooth appearance and uniform freedom of movement. However, ECPH can be challenging to knit with yam quality being critical, thus making ECPH more costly to produce. Further, ECPH appears deceptively opaque and undersized before boarding due to high contraction of the elastane.
• Spandex garments prepared from traditional every course style such as ECPH are known and produced mainly for their superior comfort, stretch and uniformity.
• some knitters and retailers claim not being able to make a“glossy” or“shiny” sheer garment using a typical ECPH structure with covered yams due to the twists of the polyamide eliminating most of its shine.
• Negative aspects including, but not limited to, touch, fragility and cheap appearance make a sheer, light weight ECPH prepared via a bare knitting technique without a covered yarn component undesirable.
• An aspect of the present invention relates to a knitted fabric prepared from a modified every course style which comprises courses of spandex covered with rigid yarn and courses of bare spandex plated with rigid yam.
• the fabric is knit in a repeating pattern comprising a course of spandex covered with rigid yarn followed by a course of bare spandex plated with rigid yarn.
• the fabric is knit in a pattern comprising two or more courses of spandex covered with rigid yam followed by a single course of bare spandex plated with rigid yam.
• the fabric is knit in a pattern comprising one or more courses of spandex covered with rigid yam followed by two or more courses of bare spandex plated with rigid yam.
• the rigid yam comprises a polyamide.
• Another aspect of the present invention relates to a garment, at least a portion of which is prepared from fabric having a modified every course style which comprises courses of spandex covered with rigid yam and courses of bare spandex plated with rigid yam.
• the garment is hosiery.
• Another aspect of the present invention relates to a method for improving comfort and/or increasing gloss of an elastified knitted fabric or garment thereof.
• the method comprises preparing at least a portion of the garment from a fabric comprising courses of spandex covered with rigid yam and courses of bare spandex plated with rigid yarn.
• Yet another aspect of the present invention relates to a method for lowering cost of an ECPH elastified knitted garment.
• the method comprises preparing at least a portion of the garment from a fabric comprising courses of spandex covered with rigid yarn and courses of bare spandex plated with rigid yam.
• FIGs. 1 A- 1C are diagrams comparing typical every course panty hose constmction (FIG. 1 A), typical alternate course panty hose construction (FIG. IB) 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).
• fabrics prepared from a modified every course style with courses of spandex covered with rigid yam and bare spandex plated with rigid yam are provided by this disclosure.
• 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.
• 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.
• spandex bare spandex plated with rigid yam. Any spandex suitable for the fabrics of this disclosure can be used in one nonlimiting embodiment, the spandex is fusible.
• any rigid yarn can be used in the present invention.
• Nonlimiting examples may comprise polyamide, polyester or polypropylene.
• the rigid yam 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.
• 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 ran resistant garments with shine.
• FIG. 1C depicts a repeating pattern comprising a course of spandex covered with rigid yam followed by a course of bare spandex plated with rigid yam.
• 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 yam.
• the fabric can be knit in a repeating pattern comprising two or more courses of spandex covered with rigid yam followed by a single course of bare spandex plated with rigid yam.
• 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 yam followed by courses of bare spandex plated with rigid yam.
• fabric is prepared by weft knitting.
• other yams are added to the feeds to, for example, make the fabric heavier or to introduce design, pattern and/or color to the fabric.
• 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 yam and courses of bare spandex plated with rigid yarn.
• the garment is a sheer garment.
• the garment has an 8 to 20-25 denier appearance.
• the garment is hosiery or intimate apparel.
• the fabric of the present invention may be used in the leg portion which the panty or other sections may comprises fabrics with typical
• the garment is non-sheer.
• 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 fsl.
• 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 fsl.
• 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,
