What is Feather Yarns

　　The weft yarn is interwoven back and forth between two sets of warp yarns on a crochet machine, and then the weft yarn between the two sets of warp yarns is cut in the middle with a razor blade, and the weft yarn stands upright on the warp yarn to become a feather yarn. The length of the feather depends on the spacing between the two groups of warp yarns, and the feather is long after the spacing is large, and vice versa. There are big feather yarn and small feather yarn, the feather length of big feather yarn is more than 10mm, and the feather length of small feather yarn is less than 10mm. Most of the warp yarns used for feathers are polyester or nylon filaments, while the weft yarns are made of triangular polyester or nylon filaments with better luster, and also with lighted viscose staple fiber yarns. Its taking performance is good and warm, so it is suitable to be used in a large number of clothes, hats, scarves, socks and gloves, and the products have great repercussions in the market, especially the growing demand in foreign markets. Feather yarn is a product with high economic benefit and good development prospect.

　　The "backbone" part of 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, which determines the perception effect of the finished yarn.

　　The fiber of the trim yarn should be lustrous, elastic and naturally erect; 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 hair, and it is generally appropriate to use filament; the core yarn trim yarn should use the same heat shrinkage rate of raw materials to prevent the finishing and dyeing of the yarn to cause long and short hair, twist shrinkage and uneven strip.

　　Core yarn and trim yarn count is determined with the finished product count, but also affected by the number of crochet hooks. In order to make the core yarn hold the trim yarn effectively, the trim yarn should be 1-3 times thicker than the core yarn. As the fiber of core yarn, the surface of single fiber is smoother, and the fiber is easy to slip in the knife when cutting, so it is not easy to cut, but the flexing, bending resistance and tensile strength are good. Fibers suitable for use as trim yarn must be easy to cut and and have excellent optical properties and a large coefficient of friction.

　　In this way, the fabric feels thick and durable, and the pile fabric made of it can be kept full and vertical, with good puffiness and gloss.

　　What should we pay attention to in the production of feather yarn?

　　1、Choose the suitable raw material.

　　Take nylon feather yarn as an example, its raw material must be produced by imported nylon slices in order to prevent the color flower and color difference.

　　2, constant temperature treatment.

　　The raw material of nylon feather yarn should be treated with steam thermostat, otherwise it will be rolled and color blossoms.

　　3, cutter blade timely replacement.

　　If the blade is not replaced in time, it will produce serious hair loss.

　　4、Finished product inspection.

　　There will be hairless yarn and oil stained yarn in the machine, so we should inspect them and pick out the defective yarn.

　　5、Swinging.

　　Shaking and twisting must use large automatic shaking and twisting yarn, to shake out the big pattern, the frame length should be long, for the subsequent inverted feather good pouring to prepare, otherwise inverted feather will not pour out, serious loss. Stranded yarn important must be less than0.25kg appropriate, otherwise the nylon will spend.

　　5, dyeing control.

　　①Because of the nylon raw materials on the dyeing speed, not easy to dye evenly, easy to outstanding flowers, color difference, so in the dyeing finishing, shall slow heating and slow dyeing agent, different batches of nylon raw materials can not be mixed dyeing, there will be uneven coloring.

　　②The dyed feather yarn can not be dried by baking machine, such as drying will appear loose hair, color difference, poor hand feeling and other problems.

　　③On softener to ensure good handfeel.
