AI Technical Summary

Technical Problem

Conventional latch hook knitting methods create holes and seams at the raglan line, leading to bulkiness, reduced strength, and difficulty in fine adjustments, resulting in an unflattering appearance and discomfort.

Method used

The seamless crochet garments are formed continuously with yarns without cuts or knots, using short rows and reinforcement rows to create smooth slopes at the raglan line, filling gaps and enhancing strength with a dense knitting pattern.

Benefits of technology

The solution results in seamless, three-dimensional garments with smooth seams, preventing holes and stretching, ensuring a comfortable fit and improved appearance.

Abstract

In crochet, the aim is to provide seamless crochet garments that eliminate the discomfort caused by sewing together parts and that have sufficient elasticity. [Solution] The back panel, left and right sleeves, and front panel are formed continuously using a series of threads without cuts or knots. The knitted fabric employs a single crochet stitch pattern, and the uneven rib structure provides elasticity. The continuous knitting process from the back panel to the sleeves and then to the front panel creates a seamless garment without seams.

Description

Technical Field

[0001] The present invention relates to clothing formed by latch hook knitting, and particularly to seamless latch hook knitted clothing that is continuously knitted without cutting the yarn, has no holes in the knitted fabric at the switching line such as the raglan line, and has elasticity.

Background Art

[0002] Conventionally, in latch hook knitting, there has been a technique (prior art) of forming clothing in one stroke by continuously knitting horizontally from the back body to the sleeves and then to the front body without sewing the parts together (see, for example, Non-Patent Document 1). In such prior art, in order to form the angle of the boundary line (raglan line) between the body and the sleeves, techniques such as "turn-back knitting" in which a plurality of stitches are not knitted at the end of the knitted fabric and the fabric is folded back have been used.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional short-row knitting methods create a stepped shape by using multiple stitches as units, which often results in large gaps (holes) at the seams, detracting from the appearance and reducing the strength of those areas, making them prone to stretching. Furthermore, the stepped structure makes fine adjustments to the angle difficult, often leading to bulkiness and tightness under the arms when worn. In addition, conventional continuous knitting structures often result in the front and back panels being the same shape, which can lead to a tight neckline. Therefore, this invention aims to provide seamless crochet garments that maintain the advantages of being formed continuously with a single thread, while having smooth seams without holes and a three-dimensional shape that fits the body. [Means for solving the problem]

[0005] To solve the above problems, this invention forms the back body, left and right sleeves, and front body continuously with a series of yarns without cuts or knots. In forming the boundary between the body and sleeves (raglan line), a three-dimensional shape is formed by using short rows, where multiple stitches are folded back without knitting, and a "reinforcement row" is knitted into the stepped end created by the short rows using regular single crochet, picking up two strands (heads) of the chain from the previous row.

[0006] As a result, the gaps (holes) created by the step-like steps characteristic of short-row knitting are filled and covered by the reinforcing knitting rows, and a dense knitting pattern that picks up two stitches is arranged in a band shape within the knitting pattern that picks up half stitches (rib structure), improving the strength of the raglan line and preventing stretching and deformation. [Effects of the Invention]

[0007] According to this invention, because the parts are continuous, there is no bulkiness at the seams, and the raglan lines are formed as smooth slopes rather than steps, preventing holes (gaps) in the joints, resulting in a beautiful appearance and maintained strength. In addition, the smooth slopes improve the garment's ability to conform to the body's lines, eliminating the discomfort that was a problem with conventional "one-stroke crochet sweaters." [Brief explanation of the drawing]

[0008] [Figure 1] This is an overall perspective view of clothing according to an embodiment of the present invention. [Figure 2] This is a schematic diagram showing the structure of the garment according to the present invention. [Figure 3] This is a partially enlarged view showing the knitted fabric structure (rib knit) of the present invention. [Figure 4] This is a simplified schematic diagram showing the raglan line structure of the present invention and the prior art. [Modes for carrying out the invention] [Examples]

[0009] The embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a completed drawing of the sweater according to the present invention, and Figure 2 is a schematic diagram showing its unfolded structure. The garment of the present invention is knitted in a continuous line, starting with a cast-on using chain stitches, and proceeding in the order of the back body, one sleeve, the front body, the other sleeve, and then returning to the back body.

[0010] The fabric is basically formed by working back and forth in single crochet stitches. In this process, as shown in Figure 3, by picking up only half of the top stitch of the single crochet stitch from the previous row (adjusting the pick-up position between odd and even rows), vertical ribs appear in the fabric. This structure enhances the fabric's elasticity in the horizontal direction.

[0011] In the sleeve section, stitches are increased by chain stitch or similar techniques, continuing from the body of the garment, and at the end of the knitting row, it is joined to the beginning row with slip stitch or similar techniques to form a tubular shape. This allows for a functional and three-dimensional shape, similar to a raglan sleeve, to be achieved without seams. [Explanation of Symbols]

Claims

1. A seamless crochet garment comprising a front body, a back body, and left and right sleeves, wherein the back body, the left and right sleeves, and the front body are formed by a continuous knit structure using a series of threads without cuts or knots, and there are no seams at the boundaries between the parts, characterized in that the transition line (raglan line) that forms the boundary between the body and the sleeves is reinforced by crocheting single crochet rows (hereinafter referred to as "reinforcement rows") that pick up the top two stitches of the previous row at the stepped end formed by short-row knitting, thereby closing and reinforcing the gap caused by the stepped step.

2. The seamless crochet garment according to claim 1, characterized in that the knitted structure is formed by back-and-forth single crochet, and stitches that pick up only half of the chain stitches of the previous row are arranged in a continuous or alternating manner, thereby forming an elastic, uneven rib structure on the surface of the knitted fabric.

3. The seamless crochet garment according to claim 1 or 2, characterized in that the front body and the back body are formed with an asymmetrical number of rows or shape such that the edge of the neck opening of the front body is located lower than the edge of the neck opening of the back body.
