　　What is fancy yarn?

　　Concept
　　Fancy yarn refers to the yarn with special structure and appearance effect obtained by using special raw materials, special equipment or special technology to process the fiber or yarn in the process of spinning and yarn making, which is a kind of yarn with decorative effect in yarn products.
　　Structure

　　Fancy yarns come in many different varieties and generally consist of a combination of core yarn, decorative yarn and cemented yarn.
　　The core yarn is the skeleton of the fancy yarn and the attachment of the trim yarn. Generally use high strength filament or yarn as the core.
　　The solid thread is used to fix the pattern, so that the pattern is fixed in the way it was produced, thus avoiding slippage along the length. The solid thread is mostly made of fine and high strength filaments.
　　The trim thread reflects the fancy effect. The fancy yarn patterns, such as thick details, loops and pigtails, are expressed by the trim thread. Trim threads can be produced with sliver or roving by the same drafting but different overfeed (e.g. loop yarn), or by different drafting (e.g. bamboo yarn), or with filament yarn, by different overfeed (e.g. knot yarn). The use of two roving yarns of different colors with different drafts and different overfeeds can produce fancy yarns of varying thickness and color.
　　Classification of fancy yarns

　　Fancy yarns can be classified into 3 categories according to their color and structural form.
　　Classification of fancy yarns
　　Fancy yarns are yarns with colored fibers mixed into the fibers of the base yarn in a certain proportion, so that the yarn shows distinctive colored segments and dots of different lengths and sizes, such as colored dot yarn and rainbow yarn. This kind of yarn is mostly used in women&39;s and men&39;s jackets.
　　Fancy yarns are yarns with various appearance characteristics obtained by using the principle of overfeeding, such as circle yarns, bamboo yarns, spiral yarns, knotted yarns and so on. These yarns can be used as both clothing fabrics and decorative materials. They can be used for light summer clothes and heavy winter clothes.
　　Special fancy thread mainly refers to gold and silver wire, chenille thread, etc. Gold and silver wire mainly refers to the gold and silver wire obtained by sandwiching the aluminum sheet between polyester film sheets or attaching it to the polyester film. It can be used for fabric as well as decorative sewing thread to make the surface of fabric shiny and bright. Chenille thread is a kind of special fancy yarn, that is, the fiber is held on the core yarn of the combined strands, like a bottle brush, its feel is soft, and it is widely used in flocking fabrics and spike decorative fabrics.

At the same time, since fancy yarn has great potential in color matching and pattern change, its product design and development is basically in a state of free play without technical constraints, which brings unlimited vitality and challenges to the application of fancy yarn and provides a wide platform for the development of fancy yarn fabric.
