Problems solved by technology

[0003] As disclosed in the patent document CN201010603598.5, a silk-like fabric is disclosed, by using the core yarn as polyethylene terephthalate full-drawn yarn and the sheath yarn as polyethylene terephthalate pre-drawn yarn The twisted different shrinkage composite yarn improves the feel and softness of silk-like fabrics, but such fabrics do not have the unique silky feeling of real silk fabrics, and in order to obtain a better silk-like effect, the composite yarn needs to be applied High twist, post-processing adopts concave-convex calendering and weight reduction treatment, which increases production cost

Embodiment 1

[0034] 30 denier cationic dyeable modified polyester semi-glossy pre-oriented yarn is selected as the decorative yarn, and 30 denier cationic dyeable modified polyester bright full-drawn yarn is used as the core yarn, and the decorative yarn is passed through After slow heat treatment with a contact hot plate temperature of 170°C and an overfeed rate of 20%, it is compounded with the core yarn at the interlacing nozzle to form a composite yarn with a denier of 75 denier. The length difference between the decorative yarn and the core yarn is 15%, and then the resulting composite yarn is twisted, the twist twist is 1200T / M when used as warp yarn, and the twist twist is 1600T / M when used as weft yarn, and the weft yarn is divided into S twist and Z twist, and plain weave is used for weaving The gray cloth is obtained, wherein the weft yarn S twist and Z twist are arranged at a ratio of 2:2 during weaving; the gained gray cloth is then processed through refining, relaxation, hi...

Embodiment 2

[0037]The composite yarn of Example 1 is twisted, the twist twist is 1200T / M when used as a warp yarn, and the twist twist is 2300T / M when used as a weft yarn, and the weft yarn is divided into S twist and Z twist, and the plain weave is used for weaving. Gray cloth is obtained, wherein the weft yarn S twist and Z twist are arranged at 2:2 during weaving; then the gained gray cloth is formed through engineering such as refining, relaxation, high-temperature intermediate setting, dyeing, and post-finishing processing to form the imitation silk fabric of the present invention, wherein the relaxation condition It is: temperature 130°C, time 30min; intermediate shaping conditions are: temperature 190°C, time 60 seconds; other conditions are the same as in Example 1.

[0038] The surface friction coefficient of the obtained fabric is 0.44, the hysteresis moment 2HB value is 0.0035 Ncm / cm, and the drape coefficient is 90%.

Embodiment 3

[0040] The composite yarn of Example 1 is twisted, and the warp and weft yarns are both twisted and twisted at 1600T / M, wherein the weft yarn is divided into S twist and Z twist, and the satin weave is used to weave gray cloth. 2:2 arrangement; then the gained gray cloth is processed through refining, relaxation, high-temperature intermediate setting, dyeing, finishing and other projects to form the imitation silk fabric of the present invention, and the processing conditions are the same as in Example 1.

[0041] The surface friction coefficient of the obtained fabric is 0.45, the hysteresis moment 2HB value is 0.0030 Ncm / cm, and the drape coefficient is 85%.

Abstract

The invention discloses imitation silk fabric and a production method thereof. The fabric is woven fabric formed by composite yarn, wherein the composite yarn at least comprises decorative yarn and core yarn, the decorative yarn is modified polyester pre-oriented yarn, the core yarn is modified polyester fully-drawn yarn and the composite yarn accounts for more than 50% of the fabric in weight. The surface friction coefficient of the fabric is over 0.4. The production method includes the specific steps that after delayed heat treatment is conducted on the decorative yarn, the decorative yarn and the core yarn are composited at an interweaving spray nozzle to form the composite yarn, and the obtained composite yarn is twisted; then pretreatment, dyeing and post processing are conducted to obtain a finished product; in the processing process, fabric which is dry and comfortable in hand feeling and excellent in resilience and scroop can be obtained without a special processing method.

Description

technical field [0001] The invention relates to a textile, in particular to a silk-like fabric and a production method thereof. Background technique [0002] At present, there are many silk-like products in the international market, among which the silk-like fabrics made of polyester account for more than 70%, especially shaped silk, super multifilament, textured silk and interlaced silk. In addition, modern imitation silk production mostly uses compound modified or blended modified fibers for alkali reduction treatment. The fabric made by the above method has soft hand feeling, good drapability and good gloss, but there is still a certain gap between the resilience, dryness and silky feeling and silk fabric, so the imitation silk effect is not very ideal. [0003] As disclosed in the patent document CN201010603598.5, a silk-like fabric is disclosed, by using the core yarn as polyethylene terephthalate full-drawn yarn and the sheath yarn as polyethylene terephthalate pre-dr...
