Chenille yarn is a kind of fancy yarn with a special shape and structure. It is usually spun by using two strands as the core yarn and twisting the feather yarn in the middle. Chenille yarn is composed of a core thread and broken velvet fibers. The broken velvet fibers form a plush effect on the surface. The core thread plays a role in consolidating and protecting the broken velvet fibers and maintaining the strength of the product. The core yarn is generally a strand with better strength, such as acrylic yarn and polyester yarn, but also a cotton yarn with a larger twist as the core yarn. The broken velvet material is mainly made of soft viscose fiber and cotton fiber with good moisture absorption. , You can also use fluffy, soft acrylic.

The more common “velvet/core” material combinations of chenille yarn include viscose fiber/acrylic fiber, cotton/polyester, viscose fiber/cotton, acrylic fiber/polyester and so on. Due to processing characteristics, chenille yarns are generally thicker, and their linear density is more than 100 tex. Due to the high linear density of chenille yarn and dense piles on the surface, it is generally only used as weft yarn in woven fabrics.

01 Spinning principle of chenille yarn

Conveying and positioning of the core thread: In the spinning process, the core thread is divided into an upper core thread and a lower core thread. Under the action of the traction roller, they are unwound from the bobbin and fed together. Under the action of the roller piece and the spacer piece, the upper and lower core wires are placed on both sides of the feather yarn, and they are both in the middle of the feather yarn.

Feather yarn introduction and cutting: Feather yarn is composed of two or three single yarns. The single yarn is unwound from the bobbin and twisted with the high-speed rotation of the rotary head, which increases the bundling of the feather yarn; at the same time, it is wound in the gauge. A yarn loop is formed on the sheet, and the yarn loop slides down with the rotation of the roller sheet. When the blade is cut into short feathers, these short feathers are sent to the control roller together with the upper core and merge with the lower core.

Twisting and forming: With the high-speed rotation of the spindle, the core yarn is quickly twisted, and the core yarn is firmly combined with the feather yarn by twisting to form a plump chenille yarn; at the same time, it is wound on the bobbin The tube yarn is formed.

Chenille yarn is soft to the touch and has a velvet feel. It is widely used in velvet fabrics and decorative fabrics. At the same time, it can also be used directly as a braided thread. Chenille yarn can give the product a thick feeling, make it have the advantages of high-end luxury, soft hand, plump suede, good drape, etc. Therefore, it is widely made into sofa covers, bedspreads, bed blankets, table blankets, carpets, etc. Interior decorations such as wall decorations, curtains and curtains, as well as various knitted clothing products.

02 The advantages and disadvantages of chenille yarn

Advantages: The fabric made of chenille yarn has many advantages. The curtains made of it can reduce light and shading to meet people’s different needs for light. It can also prevent wind, dust, heat insulation, heat preservation, noise reduction, and improve Room climate and environment. Therefore, the ingenious combination of decoration and practicality is the biggest feature of chenille curtains. The carpet woven from chenille yarn has the effects of temperature regulation, anti-static, good moisture absorption, and can absorb 20 times the water of its own weight.

Disadvantages: The fabric made of chenille yarn has some shortcomings due to the characteristics of its material itself, such as shrinkage after washing, so it cannot be smoothed by ironing, so as not to cause the chenille fabric to fall down and get messy. Phenomenon, especially the front of the product, will greatly reduce the appreciation of chenille yarn products.
