What is feather yarn? Feather yarn processing process and dyeing

　　Feather yarn is a kind of fancy yarn that has emerged in the domestic market in the past three to four years. Its structure consists of core yarn and trim yarn, and the feathers are arranged in a certain direction.

　　The process mainly consists of knitting and cutting, i.e. "one needle, one knife".

　　The core thread and the middle section are held by the core thread, and the two ends are cut by the cutter to form a certain length of feather trim yarn, with the feathers standing up naturally, good luster and soft hand.

　　Because of the directional distribution of the feathers, the woven fabric is not only soft and lustrous, but also rich and decorative, and the feather yarn is better than other down yarns because it is not easy to shed.

　　Its taking performance is good, warm, suitable for use in a large number of clothes, hats, scarves, socks, gloves, the product has a great response in the market, especially the growing demand in foreign markets.

　　Feather yarn is a product with high economic benefit and good development prospect.

　　Feather yarn can be produced by various fiber yarns, currently commonly used are viscose, nylon, acrylic and polyester.

　　The "backbone" 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 part of the feather yarn and determines the perception effect of the finished yarn.

　　The yarn must have good luster, elasticity and natural verticality.

　　Trim yarn strength should not be too high, should be easy to cut, can get a neat length of down, and not easy to lose hair, generally with filament is appropriate.

　　Core yarn trim yarn should use the same heat shrinkage rate of raw materials to prevent long and short hairs, twist shrinkage and uneven stripes caused by finishing and dyeing after yarn formation.

　　Core yarn, decorative yarn count determination and finished count, but also by the crochet needle number of the influence, in order to make the core yarn effective grip decorative yarn, decorative yarn should be1-3times thicker than the core yarn.

　　In this raw material selection we made a comparison and selection: with 70D / 24f semi-dull filament, monofilament surface is smooth, cutting fiber easy to slip in the knife, not easy to cut, but flexural, bending resistance, good tensile strength, can be used as a core yarn.

　　The fabric feels thick and durable, and the pile fabric made of it can keep its pile surface full and upright, with good puffiness and glossiness.

　　Process flow

　　Round head machine production → steam shaping → twisting → inspection → packing

　　Dyeing and finishing

　　Dyeing

　　The feather yarn is made of nylon and viscose raw materials, nylon is fast dyeing, not easy to dye evenly, requirements: 1.

　　1、Slow temperature rise, use slow dyeing agent.

　　2, different enterprises different batches of nylon, dyeing performance is not the same, the production of different batches of raw materials are used separately, separate packing.

　　3. The heat preservation time should not be too long, otherwise the elasticity and strength of the yarn will decrease.

　　4、Drying time and temperature should be controlled according to the characteristics of the fiber.

　　Weaving

　　When weaving the whole warp, pay attention to the direction of the fuzz. If multiple batches of yarn are mixed, use them evenly, preferably with a rapier machine. Prevent horizontal file and shadow defects.
