Description

The present invention relates to fabrics prepared from modified full-course styles having courses of spandex covered with hard yarns and courses of bare spandex plated with hard yarns, and their use in making elastic knit garments.

Two conventional options for incorporating spandex into garments such as hosiery include a full course style, as shown in FIG. 1A, and an alternating course style, as shown in FIG. 1B. Spandex fibers may be coated with polyamide, for example, or may be bare, with full courses as shown in Figure 1A, or alternating courses as shown in Figure 1B. It is woven with.

Garments such as full course panty hose (ECPH) include balanced stitching and are typically provided in higher quality garments. Typically, spandex is coated. ECPH provides a balanced, smooth appearance and uniform freedom of movement. However, ECPH can be difficult to knit because the quality of the yarn is important.
Therefore, the manufacturing cost of ECPH increases. Furthermore, due to the high shrinkage of elastane, the ECPH appears opaque and small in size prior to boarding.

Spandex garments prepared from conventional full-course styles such as ECPH are known and are manufactured primarily for their superior comfort, stretch, and uniformity. However, some knit manufacturers and retailers claim that they cannot make "shiny" or "sparkly" lightweight garments using typical ECPH constructions with covered yarns because most of the shine of the garment is eliminated due to the twisting of the polyamide.

Negative aspects include, but are not limited to, feel, brittleness, and non-premium appearance of sheer, lightweight ECPs prepared through bare knit making techniques without coated yarn components.
Makes H undesirable.

Therefore, when a shine hosiery garment is desired, the shine effect is typically provided by using a light polyamide in an alternating course (AC) configuration. Most of the shine comes from the inelastic course. Garments such as alternating course panty hose (ACPH) typically consist of alternating courses of spandex coated with polyamide and courses of spandex coated with flat or textured polyamide. Including courses. Alternating courses containing polyamide can often result in longer stitches. ACPH can increase flexibility when using polyamides, thus lowering the cost of ACPH. Additionally, ACPH can have a high shine or glossy appearance. However, thin ACPH garments are typically less comfortable, have poor row-to-row uniformity, and are unable to resist electrical wires using known engineering techniques.

There is a need for lower cost hosiery garments that have improved comfort, shine, softness, and/or wire resistance when using polyamide or other hard yarns.

One aspect of the invention relates to knit fabrics prepared from a modified full course style that includes courses of spandex that are covered with hard yarns and courses of bare spandex that are plated with hard yarns.

In one non-limiting embodiment, the fabric is knitted in a repeating pattern that includes a course of spandex that is covered with hard yarns, followed by a course of bare spandex that is plated with the hard yarns.

In an alternative non-limiting embodiment, the fabric is made of two layers of spandex coated with hard yarns.
It is knitted in a pattern that includes two or more courses followed by a single course of bare spandex plated with hard yarn.

In yet another non-limiting alternative embodiment, the fabric comprises one or more courses of spandex covered with hard yarns followed by two or more courses of bare spandex plated with hard yarns. It is knitted in a pattern that includes courses.

In one non-limiting embodiment, the hard yarn comprises polyamide.

Another aspect of the invention relates to a garment prepared at least in part from a fabric having an altered full course style that includes courses of spandex that are covered with hard yarns and courses of bare spandex that are plated with hard yarns. In one non-limiting embodiment, the garment is hosiery.

Another aspect of the invention relates to a method for improving the comfort and/or increasing the shine of elastic knit fabrics or garments thereof. The method includes preparing at least a portion of the garment from a fabric that includes a course of spandex covered with hard yarn and a course of bare spandex plated with hard yarn.

Yet another aspect of the invention relates to a method for reducing the cost of ECPH elastic knit garments. The method includes preparing at least a portion of the garment from a fabric that includes a course of spandex covered with hard yarn and a course of bare spandex plated with hard yarn.

FIG. 1A compares a typical full course pantyhose construction (FIG. 1B), a typical alternating course pantyhose construction (FIG. 1B), and a modified full course style of the present invention that includes every other course of spandex covered with polyamide and bare spandex plated with polyamide (FIG. 1C).

Provided by the present disclosure is a fabric that includes a course of spandex covered with hard yarns;
and courses of bare spandex plated with hard yarns, fabrics prepared from the modified full course style, elastic knit garments prepared from these fabrics, and methods for producing elastic knit garments with improved comfort, increased luster, and/or in some embodiments increased wire resistance at lower cost compared to fabrics prepared from conventional full course and/or alternating course styles.

As used herein, the term "spandex" is meant to also include elastane and/or Lycra.

For purposes of this disclosure, "traditional full course styles" to which improved gloss and/or wire resistance and/or cost are being compared are those knitted from spandex with all courses coated with polyamide. It means the fabric that is made of.

For purposes of this disclosure, the "conventional alternating course style" to which improvements in comfort and/or wire resistance are being compared means a fabric knitted with every other course of polyamide covered spandex or bare spandex plated with polyamide and every other course of polyamide only.

For purposes of this disclosure, "plating" or "plated" means that the hard yarns and bare spandex yarns are held in a parallel side-by-side relationship throughout the knit;
It refers to a controlled relationship between two yarns in which the spandex material is always kept on one side of the hard yarn.

The fabrics of the present disclosure are prepared from a modified full course style as the full course is elastified and therefore technically an ECPH with all its advantages in terms of comfort and stretchability.

One of the elastic courses of the fabric of the present disclosure includes spandex coated with hard yarns. The coated spandex may be single coated, double coated, or air jet coated. Important advantages of using coated yarns in the fabrics of the present disclosure include, but are not limited to, a more natural soft feel compared to plastic due to the spandex being coated and not in direct contact with the skin; soft feel, and reduced fragility compared to bare spandex.

Other elastic courses in the fabrics of the present disclosure include bare spandex plated with hard yarns. Any spandex suitable for the fabrics of the present disclosure may be used in one non-limiting embodiment, where the spandex is fusible.

Any hard yarn can be used in the present invention. Non-limiting examples may include polyamide, polyester, or polypropylene. In one non-limiting embodiment, the hard yarn is
It is polyamide. As will be understood by one of ordinary skill in the art upon reading this disclosure, any polyamide may be used, the selection of which is dependent on, but not limited to, the resulting fabric's high lightness, loft, and uniformity. , and the desired characteristics, including gloss.

By including uncovered, yet still elastic courses in the fabric of the present disclosure, hard yarns such as polyamides can shine because there are no turns to inhibit shine. Thus, the fabric of the present disclosure has a high shine compared to typical ECPH. Furthermore, the drawback of using bare spandex in some of the courses is mitigated by the other courses being covered, thereby providing a shiny, wire-resistant garment.

A variety of repeat patterns of the two elastic courses can be used in the fabrics of the present disclosure, the selection of which can depend on the garment and/or knit pattern in which the fabric is to be used.

For example, FIG. 1C shows a repeating pattern that includes a course of spandex covered with hard yarn followed by a course of bare spandex plated with hard yarn.

In an alternative non-limiting embodiment, the fabric may be knitted in a repeating pattern including a single course of spandex that is covered with a hard yarn, followed by two or more courses of bare spandex that are plated with the hard yarn.

In an alternative non-limiting embodiment, the fabric may be a 200% polyester fiber woven fabric of spandex covered with hard yarns.
The fabric may be knit in a repeating pattern including one or more courses of bare spandex followed by a single course of bare spandex that has been plated with a hard yarn.

In hosiery, typically the number of feeds in the individual courses is four, which may all be the same or different.

However, in seamless knitting, typically 8 feeds are used, whereas in circular knitting 32 or more feeds are used.

As will be understood by those skilled in the art upon reading this disclosure, any of these patterns, as well as alternating patterns, may be used in accordance with the present invention; It is in no way limited to a particular repeating pattern or number of courses of spandex followed by courses of bare spandex plated with hard yarn.

In one non-limiting embodiment, the fabric is prepared by flat knitting.

In one non-limiting embodiment, other yarns are added to the feed, for example, to make the fabric heavier or to introduce designs, patterns, and/or colors into the fabric.

The present disclosure also provides that at least a portion of these fabrics have a modified full-course style, including courses of spandex that are covered with hard yarns and courses of bare spandex that are plated with hard yarns. Provide prepared clothing. In one non-limiting embodiment, the garment is a sheer garment. In one non-limiting embodiment, the garment comprises 8
It has an appearance of 20 to 25 denier. In one non-limiting embodiment, the garment is hosiery or underwear. In one non-limiting embodiment of hosiery, the fabric of the present invention may be used in the leg portions, and panties or other sections may include fabrics having typical construction. In an alternative non-limiting embodiment, the garment is not sheer.

Further provided by the present disclosure are methods for improving the comfort, increasing shine, and/or increasing wire resistance of elastic knit garments, as well as methods for lowering the cost of elastic knit garments. be. These methods include preparing a garment from at least a portion of a fabric that includes a course of spandex covered with hard yarns and a course of bare spandex plated with hard yarns.
