Introduction of Feather Yarn

Feather yarn is a very popular fancy thread in the international textile industry in recent years. Its structure consists of core yarn and decorative thread, and the feathers are arranged in a certain direction. The feather length of the feather yarn stands up naturally, with good luster and soft feel. Due to the directional distribution of hairiness, the woven fabric is not only soft in luster, but also has a plump surface and a decorative effect. Feather yarn is superior to other fluff yarns in that it is not easy to lose hair. It has good wearing performance and strong warmth retention, and should be widely used on clothes, hats, scarves, socks and gloves.

The craft of feather yarn

On the crochet machine, the weft yarns are interwoven back and forth between the two sets of warp yarns, and then the weft yarns between the two sets of warp yarns are cut with a blade in the middle, and the weft yarns stand upright on the warp yarns to become feather yarns. The length of the feathers depends on the distance between the two sets of warp yarns. The feathers are longer when the distance is large, and short otherwise. Feather yarn is divided into large feather yarn and small feather yarn. The feather length of large feather yarn is more than 10mm, and the feather length of small feather yarn is less than 10mm. The warp yarns used for feathers are mostly polyester or nylon filaments, while the weft yarns use triangular polyester or nylon filaments with better luster, and there are also bright viscose staple yarns. Feather yarn products have a great response in the market, especially the growing demand in foreign markets. Feather yarn is a product with high economic benefits and good development prospects.

The “backbone” part of the feather is the core yarn, and the quality and performance of its raw materials must meet the requirements of knitting yarns. Decorative yarn is the main performance part of feather yarn, which determines the sensory effect of finished yarn.

The decorative thread fiber of feather yarn requires good luster, elasticity, and can stand up naturally; the strength of the decorative yarn should not be too high, it should be easy to cut, and the fluff with neat length can be obtained, and it is not easy to lose hair. Generally, filament is suitable; The thread should be made of raw materials with the same thermal shrinkage rate to prevent long and short hair, twist shrinkage and uneven evenness caused by finishing and dyeing after yarn formation.

The count of the core yarn and decorative yarn of feather yarn is related to the count of the finished product, and is also affected by the number of crochet needles. In order to make the core yarn effectively hold the decorative yarn, the decorative yarn should be 1-3 times thicker than the core yarn. As the fiber of the core wire, the surface of the single fiber is relatively smooth, the fiber is easy to slip on the edge of the knife when cutting, and it is not easy to cut, but it has good flexibility, bending resistance and tensile strength. Fibers suitable as decorative yarns must be easy to cut and have excellent optical properties and a large coefficient of friction.

In this way, the fabric made of feather yarn feels thick and durable, and the fleece fabric made from the feather yarn can keep the suede plump and erect, and has better bulkiness and gloss.

Feather yarn raw material selection

Feather yarn can be produced with a variety of fiber yarns, commonly used are viscose yarn, nylon yarn, acrylic yarn and polyester yarn. Taking the 1/6.5Nm bright nylon feather yarn as an example, the core yarn adopts 70D/24f semi-dull nylon filament yarn, and the decorative yarn adopts two 75D/24f three-leaf bright nylon filament yarns to feed, which can ensure the successful production. yarn quality. We have compared and screened the selection of this raw material: 70D/24f semi-matte filament yarn, single fiber surface is relatively smooth, the fiber is easy to slip on the edge of the knife when cutting, and it is not easy to cut, but the flexibility, bending resistance, tensile strength Good tensile strength, can be used as a core wire. The 75D/24f trilobal section has optical fibers, which are easy to cut, have excellent optical properties, and have a large coefficient of friction, which is more suitable for decorative yarns. The fabric feels thick and durable, and the fleece fabric made of it can keep its suede plump and erect, and has good bulkiness and gloss.

Production of feather yarn

The production process of feather yarn is round head machine production → steam setting → twisting → inspection → packing.

Round head production

Round head production is the key to feather yarn forming. There are 15 needle positions in the needle cylinder of the round head machine. The distance between 1 and 15 adjacent needle positions is from large to small. First, the latch needle and cutting force are loaded into the specified needle position according to the process design. The core yarn and decorative yarn are introduced through two guide yarns respectively. The core yarn is put into the latch needle and woven into the core yarn. The decorative yarn is first put into the cutting knife, rotated with the needle cylinder, and then introduced into the latch needle together with the core yarn. , through the movement of the latch needle to complete the bending, looping, and looping. There is a protruding chamfer on the top of the cutter. When the cutter and the latch needle move downward together to escape the loop, the inserted yarn will not come out of the cutter bar. When the latch needle moves upward to make the loop, the cutter also moves upward, and the decorative thread on the cutter falls off the lower edge of the cutter and is cut off to form hairiness. The decorative yarn participates in the weaving of the core yarn, is held by the core yarn, and is not easy to fall off, and the length of the feather is related to the distance between the latch needle and the cutter. When on the machine, pay attention to the position of the two yarn guides to meet the requirements, so as to ensure that the core yarn and decorative yarn of the feather yarn are correctly placed on the latch needle and the cutter respectively.

The cutting knife should be kept sharp, and the decorative yarn should be moved to the knife edge to successfully complete the cutting yarn, otherwise it will break due to accidental stretching, which will cause the phenomenon of long and short hairs.

In the process of producing feather yarn, the needle cylinder rotates, and the crochet needle and the cutter move up and down. Due to the friction of the needle cylinder, the yarn will overheat and shrink when passing through the needle cylinder, especially for nylon. quality. Need to add lubricating oil to the syringe regularly to reduce friction and cool down. The lubricating oil is spindle oil, preferably high-speed spindle oil, but not butter. Butter is completely dissolved at 85C, and the lubricating effect is reduced.

steam setting

The rotation of the needle cylinder during production has a twisting effect on the feather yarn. In order to eliminate the internal stress of twisting and prevent the yarn from being braided, it is necessary to heat-set the feather yarn off the machine. Generally, steam setting is used.

In order to make the yarn steaming effect good, the package should not be too large, generally 0.2kg/tube; the yarn tube adopts a hollow mesh with a good air permeability; according to the characteristics of the fiber, select the appropriate steaming temperature and time, too low to achieve the final shape The purpose is to affect the yarn quality too much and waste energy. For example, the steaming temperature of 1/6.5Nm glossy nylon feather yarn is 80-85℃, and the time is 30 minutes.

shake

After the yarn is steamed, no cooling is required, and the yarn is directly shaken. On the one hand, the water absorbed during the steaming can be released by the centrifugal airflow generated by the yarn, and the feathers can be straightened through the yarn guide when the yarn is shaken. The rapid cooling of the yarn is conducive to maintaining the beauty of the feather yarn and protecting the quality of the yarn.

The glass transition temperature of nylon fiber is low, the dyeing speed is fast, and it is easy to dye flowers. The weight of each skein should be appropriate, generally 0.5 pounds per skein.

test

The main defects of feather yarns are long and short hairs, thin and uneven hairs and light yarns without feathers, which should be sorted.

Bale

In order to prevent the feathers from lodging on the feather yarn, it is not advisable to pack it tightly. It is better to loose the small pack, which can be directly sent to the dyeing factory for processing. If long-distance transportation is required, it can be packed in large packages and disassembled after arriving at the destination to restore elasticity.

Dyeing process of feather yarn

Feather yarn generally uses nylon yarn and viscose yarn as raw materials. The dyeing speed of nylon fiber is fast, but it is not easy to dye evenly, so there are the following requirements when dyeing:

1) Warm up slowly and use a retarder.

2) Different batches of nylon yarns from different enterprises have different dyeing properties. During production, different batches of raw materials are used and packaged separately. 3) The holding time should not be too long, otherwise the elasticity of the yarn will decrease and the strength will decrease.

4) The drying time and temperature are also reasonably controlled according to the characteristics of the fibers.
