Double-core package yarn device long filament cake placement - warp and weft Tianying

The double-core package yarn device produced by Jinzhong Jingwei Tianying uses three methods for placing the long filament cakes: hanging, flat, and roller support. Each core filament's stretching multiple can be independently controlled, allowing for the spinning of double-core package yarns in different Specifications according to user requirements.

The Applications and Characteristics of Double Core Yarn

Double-core yarn is made from short fibers as the outer wrapping material, with two different types of long fibers as core yarns twisted together. Due to the different properties of the two core yarns, a strong complementarity is created, giving the yarn superior characteristics. For example, cotton-wrapped T400 + spandex. The characteristics of T400 are: good bulkiness.

Application of Spandex Core Yarn

The use of spandex in clothing began with the three openings (neckline, cuffs, and leg openings) of knitted underwear. Previously, knitted underwear mostly used pure cotton materials, which lost elasticity after washing, causing the openings to deform, making them neither warm nor aesthetically pleasing. Since the advent of spandex, the ribbing of the three openings in knitted underwear has adopted a weaving process that incorporates bare spandex yarn.

Application of Long Filament Core Spun Yarn

Core-spun yarn is a type of fine yarn that has a long filament as the core and is wrapped with short fibers, combining the excellent physical and mechanical properties of both the core filament and the wrapped short fibers. Commonly used core materials include polyester filament, nylon filament, and spandex filament. The wrapped short fibers are often made of cotton, polyester/cotton, acrylic, wool, etc. Core-spun yarn is mainly used for sewing threads, shirt fabrics, jacquard fabrics, and elastic fabrics. Knitted fabrics or denim made from this core-spun yarn are flexible and comfortable to wear.

Characteristics of double-core wrapped yarn

Double-core wrapped yarn is made from short fibers as the outer wrapping material, and two different types of long fibers as the core yarn, spun together through twisting. Due to the different properties of the two core yarns, a strong complementarity is created, giving the yarn superior characteristics. For example, cotton-wrapped T400 + spandex.

Exploring various spinning methods of core-spun yarns

Core-spun yarn, this unique composite structure yarn, is made by tightly wrapping core yarn with outer fibers, resulting in a compact structure and uniform thickness. Its core-spun structure allows core-spun yarn to not only break through the single functional limitations of ordinary ring-spun yarn but also integrate the appearance and feel of the outer fibers with the excellent performance of the core yarn. This complementary characteristic makes core-spun yarn superior in overall quality and highly favored by people. Next, we will introduce several spinning methods for core-spun yarn.
