Description

Imitated silk spandex core-spun yarn

Technical Field

The utility model belongs to the technical field of the textile yarn technique and specifically relates to an imitative pure silk spandex covering yarn.

Background

The real silk fabric is soft and smooth in texture, soft and light in hand feeling, rich and colorful in patterns, cool and comfortable to wear, and mainly used as fabrics of shirts, pajamas, one-piece dresses and the like in summer, headdresses and the like. The real silk is made of protein fiber, has good biocompatibility with human body, soft and smooth texture, low friction coefficient and good clothing performance. The silk monofilament has very small fiber fineness, and in addition, the hollow structure of the silk monofilament is easy to distribute water, can absorb the water in the air, has certain water locking performance, and enables the skin to feel fresh and not dry in a dry environment. Under the condition of high temperature in summer, the real silk has good moisture-dissipating performance, so that people feel cool and comfortable when wearing the real silk. It contains 18 kinds of amino acids essential for human body, and can provide skin with required nutrients and health care function. However, the real silk producing area and the real silk yield are always limited, the cost is high, and the ever-increasing consumption requirements of people cannot be met. After the real silk absorbs ultraviolet light, the fabric is easy to yellow, and in addition, the fabric is easy to age and poor in wrinkle resistance. The artificial silk fabric which is regarded as a substitute of real silk is developed rapidly along with the upgrade of consumption. However, the silk-like fabric prepared by most yarns has the advantages of relatively hard hand feeling, insufficient softness, poor moisture absorption and moisture conductivity, poor clothing feeling and unsuitability for the requirements of modern people on the fabric. How to develop a yarn makes the silk-like fabric made of the silk-like fabric soft in hand feeling and close to the silk fabric in gloss become a demand.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment is described in detail with reference to fig. 1. The silk-like spandex core-spun yarn related to the embodiment comprises a core yarn 1 and a coating layer 2. The core yarn 1 is spandex filament yarn; the coating layer 2 is a terylene FDY fully drawn yarn with the specification of 50D/48F. In this embodiment, each monofilament of the FDY polyester fully drawn yarn has a circular cross-section. The fineness of the used spandex is 20D, the feeding ratio of the spandex is 1.2-1.5 when the core-spun yarn is prepared, namely the spandex is stretched to 120% -150%, and the spandex and the FDY fully drawn yarn are simultaneously fed to prepare the silk-like spandex core-spun yarn, and the twist of the core-spun yarn is 1600-2000T/m. Specifically, in this example, the stretch feed ratio of spandex was 1.2 and the twist was 1800T/m. The silk-like fabric prepared from the silk-like spandex core-spun yarn in the specification has softer hand feeling.

Example two

This embodiment will be described in detail with reference to fig. 2. The silk-like spandex core-spun yarn related to the embodiment comprises a core yarn 1 and a coating layer 2. The core yarn 1 is spandex filament yarn; the coating layer 2 is a terylene FDY fully drawn yarn with the specification of 50D/48F. The cross section of at least one monofilament in the FDY polyester fully drawn yarn comprises a monofilament 21 with a circular cross section and a protrusion 22 arranged on the outer peripheral surface of the monofilament 21. In this embodiment, the cross-section of the monofilament of the FDY polyester fully drawn yarn is composed of a monofilament 21 having a circular cross-section and a protrusion 22 provided on the outer circumferential surface of the monofilament 21. The polyester yarn with the special-shaped cross section can enable light rays to be reflected unevenly on the surface of the yarn, so that the silk-like fabric prepared from the silk-like spandex core-spun yarn has soft hand feeling and luster close to that of silk. And the monofilament forming the terylene FDY fully drawn yarn has a hollow structure, so that the terylene FDY fully drawn yarn has a certain warm-keeping function, and the defect that the imitated silk fabric is not warm-keeping can be overcome.

EXAMPLE III

An example according to the present embodiment will be described in detail with reference to fig. 3. The silk-like spandex core-spun yarn related to the embodiment comprises a core yarn 1 and a coating layer 2.
