Chenille yarn, also known as broken-fiber yarn, is a type of fancy yarn with a unique shape and structure. The product consists of a core yarn and broken-fiber fleece fibers. The broken-fiber fleece fibers create a plush effect on the surface, while the core yarn serves to bind and protect the fleece fibers, maintaining the product's strength. The core yarn is generally a high-strength ply yarn, such as acrylic or polyester yarn; some products use high-twist cotton yarn as the core. The fleece material is mostly soft, moisture-wicking viscose or cotton fibers, but fluffy, soft acrylic fibers can also be used.
Common "fleece/core" material combinations for chenille yarn include viscose/acrylic, cotton/polyester, viscose/cotton, and acrylic/polyester. Due to its processing characteristics, chenille yarn is generally relatively coarse, with a linear density mostly above 100 tex, commonly 666.7 tex, 285.7 tex, 222.2 tex, and 142.8 tex.
Chenille yarn is widely used in heavy and medium-weight curtain fabrics and furniture fabrics, but rarely in clothing fabrics.
Products are available in piece-dyed and printed varieties as well as yarn-dyed jacquard. Due to its high linear density and densely piled surface, chenille yarn is generally used only as weft yarn in woven fabrics.
Products consist of a core yarn and broken velvet fibers. The broken velvet fibers create the plush effect on the surface, while the core yarn serves to bind and protect the broken velvet fibers and maintain the product's good strength. The core yarn is generally a high-strength ply yarn, such as acrylic or polyester yarn; some use high-twist cotton yarn as the core yarn. The broken velvet material is mostly soft, moisture-wicking viscose or cotton fibers, but fluffy, soft acrylic fibers can also be used.
This technology provides a recycled polyester chenille yarn, made by plying recycled DTY low-elasticity network yarn and recycled polyester ply yarn. This technology also provides a method for manufacturing recycled polyester chenille yarn, which is made by plying recycled DTY low-elasticity network yarn and recycled polyester ply yarn. This technology further provides a method for manufacturing a recycled polyester chenille yarn blanket, comprising the following steps: preparing recycled polyester chenille yarn; and weaving a recycled polyester chenille yarn blanket using recycled polyester chenille yarn of appropriate thickness.
The technology also addresses chenille core yarn with low-temperature melt bonding properties and its spinning process, specifically providing a core-sheath composite fiber material suitable for use as chenille core yarn and a process for spinning non-shedding chenille yarn using it. According to the technical solution provided by this technology, the core-sheath composite fiber used as chenille core yarn is spun from 15-30% low-melting-point modified polyester and 70-85% conventional polyester, wherein the core layer is conventional polyester and the sheath layer is low-melting-point modified polyester. This chenille core yarn is ring-twisted with a fleece yarn to form chenille yarn, and after baking at a certain temperature, the low-melting-point sheath layer partially melts and coats the contact points between the core yarn and the fleece yarn, thereby enhancing the bonding strength between the fleece yarn and the core yarn. When using this core yarn to spin chenille yarn, it can overcome the shortcomings such as easy shedding of the velvet, low yield, inability to be disassembled and washed, and stiff hand feel.
