False twist:

The false twist twist is uniform, the tension is consistent, and the processing range is wider. This kind of twisted silk also has the potential to curl and twist, with its production of artificial silk, silk surface is elastic, soft feel, soft luster, especially suitable for imitation of crepe de chine, imitation of heavy crepe and crepe satin plain production.

This kind of imitation silk is the use of ordinary polyester filament in the twisting machine twisting, untwisting, constantly moving forward, and finally after a certain temperature setting, the silk shape fixed down. Due to the proper speed control, it is generally lower than the speed of the chemical fiber twister. The temperature of the setting is appropriate, and it is generally lower than that of the chemical fiber setting.

The determination of the speed and temperature of ZuiJia is determined by the material and nature of the silk being twisted and varies from filament to filament. Therefore, this kind of twisted silk maintains a certain twist, retains the elasticity of curling and stretching, and the woven silk strips have a certain pattern, which can be comparable to silk crepe de chine.

Even an expert person can hardly tell the difference between imitation silk and real silk just from the appearance and feel for a while. And its color fastness and other aspects are better than silk products. The products woven with false twist silk have not only entered the high-end product series, but the sales price per meter can be increased by more than 30%, which improves the added value of the products.

False twist Yarn is also called DTY (Draw textured Yarn), also known as elastic yarn. DTY's network wire is made by using POY as the raw wire, stretching and false twist deformation processing. It is often elastic and contractile. (Generally divided into network and no network wire, network means network node)

Network filament refers to the filament in the network nozzle, through the action of jet air, the monofilament intertwined with each other and formed a periodic network point. Network processing is mainly used in the processing of POY, FDY and DTY. The low elastic network yarn produced by the combination of network technology and DTY technology has not only the fluffiness and good elasticity of deformed silk, but also many periodic and network points, which improves the tightness of the filament, saves several processes of textile processing, and can improve the ability of the filament through the water jet loom.

POY:

pre-oriented yarn: pre-oriented yarn or partially oriented yarn. It refers to the incomplete stretch of chemical fiber filament obtained by high-speed spinning with a degree of orientation between the unoriented filament (UDY) and the stretched filament. Compared with undrawn yarn, it has a certain degree of orientation and good stability, and is often used as a special yarn for stretching false twist textured yarn (DTY). (Generally not used for weaving)

FDY:

Fully stretched silk. Full name: fully draw yarn. A synthetic fiber filament further prepared by spinning and drawing. The fibers have been stretched sufficiently to be used directly in textile processing. (usually called filament)

POY and FDY:

The spinning speed of high-speed spinning is 3000 to 6000m/m in. The winding yarn with a spinning speed lower than 4000m/m in has a high degree of orientation and is called pre-oriented yarn (POY).

If the stretching effect is introduced in the spinning process, the winding yarn with high orientation and medium crystallinity can be obtained, which is a fully drawn yarn, commonly known as FDY (fully draw yarn).

DT: The stretch Twist wire is called DT (Draw Twist).

DT can be obtained by taking POY as the prefilament by drawing and twisting machine, drawing mainly and giving a small amount of twist.

100D/36F, 150D/36F, 50D/18F, etc., these are the representation of fiber specifications.

The data above the diagonal line indicates the fiber's densification, D is the fiber's densification unit "denier", that is, in the standard state, expressed in grams of 9000 meters of fiber, such as 100 grams of weight is 100 denier (100D);

The data below the slanted line indicates the number of holes used in the spinneret when spinning, and also indicates the number of monofilament strands that the filament of this specification has, such as 36F, which means that the spinneret used in spinning has 36 holes, that is, the fiber has 36 monofilament.

Large light, semi-extinction, full extinction: In order to eliminate the luster of the fiber, titanium dioxide (T iO 2) is added to the melt to reduce the luster of the fiber.

If T iO 2 is not added to the melt as a luminous filament (or a large luminous filament), 0.3% is added as a semi-extinct filament, and more than 0.3% is a fully extinct filament.

50D/18F iron:

For 50 denier 18 holes, iron pipe roll. 75D/36F paper: 75 denier 36 holes, paper tube roll. 150D/36F cations: 150 denier 36 holes, improved dyeing properties by cations.

210D/72F Slim Silk:

It is 210 denier 72-hole bamboo thread." "Fat thin silk" is a non-standard textile term, generally understood as "bamboo thread", that is, a periodic section of thick and thin silk.
