Problems solved by technology

When the composite yarn obtained by this twisting method is used for air-jet weaving, there will be the following disadvantages: 1. Double-jet weaving cannot be used
The double-jet weaving process cannot be used, resulting in the inability to realize the alternate use of several weft yarns in the weaving process, and it is very easy to have color difference during dyeing
2. Because the composite yarn formed by twisting is easy to untwist, the monofilament in the polyester filament is easy to be blown off by the airflow during the air-jet processing
In order to ensure that the monofilament is not blown off, it is necessary to reduce the jet pressure of the air-jet loom, the size of the jet pressure is directly related to the weaving speed, reducing the jet pressure of the air-jet loom will reduce the weaving speed of the loom, and the production efficiency will be low

Embodiment 1

[0011] In order to overcome the hand feel problem of chemical fiber fabrics, fine denier chemical fibers are used for weaving, so that the fabrics have excellent hand feel. The commonly used yarn is the composite yarn obtained by twisting and compounding fine-denier polyester multifilament and spandex, so that the woven fabric not only has the excellent elasticity of spandex, but also has the excellent hand feeling brought by fine-denier chemical fiber. However, in the double-jet weaving process of the conventional twisting and compounding method, the gas ejected from the gas nozzle makes the twisted composite yarn untwisted, causing weaving defects in the fabric and easy formation of color difference on the surface of the fabric. And because the nozzle makes the twisted composite yarn untwisted, the composite yarn disintegrates, and the monofilament that makes up the polyester multifilament will be blown off by the gas ejected from the nozzle during the weaving process, which ...

Embodiment 2

[0018] The difference between this embodiment and Embodiment 1 is that the density of the bonding points on the air-deformed composite filament is 80 / meter, and the diameter of the bonding point is 2.5 mm; The air pressure applied to the pressurizing device is 4.5kg.

[0019] The specification of the spandex filament used in this embodiment is 40D / 5F; the specification of the polyester multifilament is 100D / 144F.

Embodiment 3

[0021] The density of bonding points on the air-deformed composite wire is 100 / meter, and the diameter of the bond point is 3mm; the air pressure applied to the pressurizing device of the cylinder when producing the air-deformed composite wire is 5.0kg .

[0022] The specification of the spandex filament used in this embodiment is 40D / 5F; the specification of the polyester multifilament is 75D / 144F.

Abstract

The invention discloses a production method of elastic fine-denier polyester and elastane composite filament fabric. Weaving is conducted with an air-jet loom, the weaving means of double nozzles or multiple nozzles is adopted, and used weft yarns are air textured composite filaments composed of polyester multifilaments and elastane filaments; the air textured composite filaments are provided withentanglement points, so that the polyester multifilaments and the elastane filaments are broken apart by gas flow at the entanglement points, and the polyester multifilaments are entangled with the elastane filaments. According to the production method of the fine-denier polyester and elastane composite filament fabric, a traditional twisting composite means is replaced with an air textured composite means, so that the fine-denier polyester and elastane composite filaments are not broken apart to form a woven defect and color difference in the weaving process; single filaments composing polyester are unlikely to be blown off by the nozzles, and the air-jet pressure of the air-jet loom during weft insertion can be increased, so that the weaving speed is improved.

Description

technical field [0001] The invention relates to the technical field of textile fabric production, in particular to a production method of fine denier polyester spandex elastic composite silk fabric. Background technique [0002] The poor hand feeling of fabrics has always been a defect of chemical fiber fabrics. The solution is to use fine denier filaments for weaving. Usually, polyester fine denier filaments are used for compounding with spandex filaments. On the one hand, the excellent elasticity of spandex filaments can be exerted. On the other hand, it gives full play to the comfortable feel of polyester fine denier filaments, and is an important raw material for processing high-quality elastic and good-feeling fabrics. At present, the composite method of fine-denier polyester and spandex adopts the twisting method, and the purpose of compounding is achieved through the cohesion of polyester fine-denier filaments and spandex, and the weaving is generally completed on an ...
