Knitting lace is the first thing that comes to mind when you think of Mapu. Between the lanes, the sound of loom is heard in every house; inside the factory, the production does not stop. In April 2015, the yarn industry in Mapu underwent an overall technical improvement and machine innovation, adding two main processes of doubling twist and sizing to the original process, successfully completing the transformation from rough processing to deep processing, doubling the output and turning the yarn from an accessory to a main material. This means that the product can be made into clothing that directly touches the skin. Through these changes, the quality of the product has been improved, and naturally, it has gained market recognition and achieved a "transformation" of the yarn in terms of hardware and software.
　　Fancy yarn is composed of warp-core and weft-feather (feather formed by cutting the weft thread with a blade). It is mainly used for jackets, knitwear, scarves, gloves, socks, accessories, carpets ......
　　The core yarn and the middle section are held by the core yarn formed by single knitting, and the two ends are cut off by the cutter to form a certain length of hair feather decorative yarn with natural vertical feathers, good luster and soft handfeel. Because of the directional distribution of the feathers, the woven fabric is not only lustrous and soft, but also rich and decorative, and the fancy yarn is better than other down yarns in that it is not easy to lose feathers. Its taking performance is good and its warmth is strong, so it is suitable to be used in a large number of clothes, hats, scarves, socks and gloves, and the products have a great response in the market, especially the growing demand in foreign markets. Fancy yarn is a product with high economic benefit and good development prospect.
　　Fancy yarn raw material selection
　　Fancy yarn can be produced by various kinds of fiber yarn, currently the common ones are viscose, nylon, acrylic and polyester. The "backbone" part of the feather is the core yarn, whose raw material quality performance must meet the requirements of knitting yarn.
　　The trim yarn is the main expressive part of the fancy yarn and determines the perception of the finished yarn. The fiber of the trim yarn should have good luster, elasticity and natural erection; the strength of the trim yarn should not be too high, it should be easy to cut and get a neat length of down, and it is not easy to lose feathers, and it is generally appropriate to use filament; the trim yarn of the core should use the same heat shrinkage rate of raw materials, in order to prevent the long and short feathers, twist shrinkage and uneven striping caused by finishing and dyeing after yarn formation.

　　Fancy yarn production requirements
　　The cutting knife for producing fancy yarn should be kept sharp, and the trim yarn moved to the knife should be able to finish cutting smoothly, otherwise it will break due to accidental stretching and will cause the phenomenon of long and short wool to happen. The domestic cutter needs to be replaced in 24 hours, although the cutter consumes a lot, but the comprehensive effect will be good.
　　The needle barrel rotation has a twisting effect on the fancy yarn during production. In order to eliminate the twisting internal stress and prevent the braid yarn, the fancy yarn under the machine needs to be heat-set, and steam setting is generally used.
　　On the one hand, the water absorbed during steaming can be released through the centrifugal airflow generated by yarn shaking, and on the other hand, the yarn can be straightened out by the yarn guide during yarn shaking. The yarn is cooled quickly, which is good for the fancy yarn to keep beautiful and protect the quality of the yarn.
　　Fancy yarn washing
　　Dry cleaning is best for woolen garments, but hand washing is also possible. Soap or neutral detergent should be used for washing, and special detergent for wool should be used, the temperature should not exceed 40℃, otherwise it will produce shrinkage, affect the feel and elasticity, and destroy the molecular structure of wool.
