Embodiment 1

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

Embodiment 2

[0101] Two original yarns obtained in embodiment 1 are paralleled and made into the original yarn of 167dtex / 72f, with this original yarn in No. 32 circular knitting machines with 22.0cm / 100 stitches wale (than described later The condition of comparative example 2 fiber is long 10%) Weaving length is carried out weaving, manufactures 44 courses / 2.54cm, the smooth fabric natural color cloth of 46 wales / 2.54cm density.

[0102] The same process as in Example 1 was carried out on the natural color cloth of the fabric to obtain a fabric with 56 courses / 2.54cm and 58 wales / 2.54cm. Table 1 shows the evaluation results of the obtained fabrics.

Embodiment 3

[0108] Two raw yarns obtained in embodiment 1 are paralleled to make the raw silk of 167dtex / 72f, with this raw silk on No. 22 circular knitting machines, weave into length 32.8cm / 100 coil wales (than described later The condition of the PET fiber of the comparative example 3 is long 10%) to weave, make 32 courses / 2.54cm, the natural color cloth of the smooth fabric of 36 wales / 2.54cm density.

[0109] The natural color cloth of this fabric was subjected to the same treatment as in Example 1 to obtain a fabric with 40 courses / 2.54 cm and 44 wales / 2.54 cm. The evaluation results of the obtained 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...
