1. Character and function of textured yarn
Deformed yarns are evolved from ordinary yarns, that is, ordinary synthetic filament yarns are deformed to change their appearance and have various bending shapes. Yarn is on the structure and common yarn, but of yarn and clothing material are greatly improved hygroscopicity, permeability and softness, elasticity and thermal performance, keep the yarn fabric is not only the anti-wrinkle protection type of synthetic fiber itself, but also has the good comfort of natural fiber fabric, compared with common yarn is enlarged the scope of use.
Yarn excellent performance from the following reasons: because curly appearance is conducive to the formation of air layer in the yarn, increased the warmth retention property of yarn, and make single filament separation with deformation processing, the breeze can through by the textured yarn fabric made of clothing, to strengthen the heat exchange and moisture evaporation, this process helps to wearing comfort. At the same time, the surface hair and loose shape can make the fabric not close to the skin, thus enhancing the softness of the feel. It can be used to weave fabrics similar to natural fibers, such as wool, silk, linen and other products.

2. Character and function of fancy yarn
Fancy yarns are different from ordinary yarns in structure because of different processing methods. The basic structure of fancy yarn is composed of three parts: core yarn, decorative yarn and fixed yarn.
Core yarn - located in the center of the yarn, is the main part of the strength of the yarn;
Decorative yarn - to form the fancy effect of fancy yarn and play a decorative role;
Fixed yarn - a pattern used to fix the yarn.
Therefore, fancy yarn is not as strong as ordinary yarn in terms of strength and wear resistance, and is easy to pilling and hook, but it is superior to ordinary yarn in terms of appearance performance. It can get novel and unique appearance effect by making various patterns and matching various colors. Fancy yarns can be used not only to process clothing materials, such as weaving various yarn-dyed maid's suede, tweed, but also decorative materials, such as all kinds of hand-knitted wool, window fancy yarn basic structure curtain furniture and other decorative fabrics, the pattern on the fabric is prominent, three-dimensional sense is strong, unique style.
