Example Embodiment

[0092] [Example 1]

[0093] The PTT with reduced viscosity (ηsp / c)=0.8 was spun at a spinning speed of 1200 m / min at a spinning temperature of 265°C to obtain an undrawn yarn. Then, the undrawn yarn was stretched and twisted under the conditions of a hot roll temperature of 60°C, a hot plate temperature of 140°C, a stretching ratio of 3 times, and a stretching speed of 800 m / min to obtain a stretched yarn of 84 dtex / 36f. The strength, elongation, elastic modulus, elastic recovery rate at 10% elongation, and organic boiling water shrinkage rate of the stretched yarn are 2.9 cN / dtex, 45%, 24 cN / dtex, 94% and 14%, respectively.

Example Embodiment

[0100] [Example 2]

[0101] The two raw yarns obtained in Example 1 were combined into a 167dtex / 72f raw yarn, and the raw yarn was used to wale 22.0cm / 100 stitches in a No. 32 circular knitting machine (compared to the later described The fiber of Comparative Example 2 was knitted with the woven length of the fiber (condition length 10%) to produce 44 courses / 2.54 cm, 46 wales / 2.54 cm density of smooth fabric natural color cloth.

[0102] This woven natural color cloth was subjected to the same treatment as in Example 1 to obtain a fabric of 56 courses / 2.54 cm and 58 wales / 2.54 cm. The evaluation results of the obtained fabric are shown in Table 1.

Example Embodiment

[0107] [Example 3]

[0108] The two raw yarns obtained in Example 1 were combined to make a 167dtex / 72f raw thread, and the raw thread was woven on a No. 22 circular knitting machine with a length of 32.8cm / 100 wales (compared to that described later). The condition of the PET fiber of Comparative Example 3 (10% length) was knitted to produce a natural color fabric of a smooth fabric with a density of 32 courses / 2.54 cm, 36 wales / 2.54 cm.

[0109] This woven natural color cloth was treated in the same manner as in Example 1 to obtain a woven fabric of 40 courses / 2.54 cm and 44 wales / 2.54 cm. The evaluation results of the obtained woven fabric are shown in Table 1.

Abstract

The present invention is a weft-knitted fabric, which is characterized in that it contains polytrimethylene terephthalate fiber strands, and according to JIS-L-1018, the constant load elongation in the weft direction measured at a load of 19.6N per 2.5cm width The percentage ranges from 80 to 250%, and it has a smooth and soft hand feeling, excellent stretch performance and elongation recovery performance, and excellent wearing comfort.

Description

technical field [0001] The present invention relates to a weft-knitted fabric, in particular to a weft-knitted fabric with a smooth and soft feeling, excellent stretch properties and elongation recovery properties, and excellent wearing comfort. Background technique [0002] Conventionally, weft knitted fabrics mainly composed of polyethylene terephthalate (hereinafter referred to as PET) and nylon fibers which are synthetic fibers are widely used for interior and exterior. However, although the weft-knitted fabric with PET fiber as the main component has the characteristics of non-ironing, dimensional stability and yellowing resistance, it has problems such as hard hand feeling, insufficient stretchability, poor drapability and wearing comfort. [0003] In addition, although weft-knitted fabrics mainly composed of nylon fibers have the soft feel of Numeri characteristics (Numeri) and a certain degree of stretching properties, they have non-ironing properties, poor dimension...
