Spandex core-spun yams are manufactured with cotton, linen, or woolas the sheath, and are mainly used in high-grade fancy fabrics denimfabrics.

There are three different types of gude devices for the spandex core spun yam:

High precision roller - made of seamless steel pipe and processed once, with chrome plating on theouter layer to increase strength, good straightness not easy to defomm, and hard to damage in the later period.

 Aluminum alloy roller with groove - This roller is made of special fomula aluminum alloy extnusionand then processed, with a hard anodizing process on the surface, which increases the surfacehardness. This roller, due to the groove, increases the friction of spandex, and the wire feeding ismore aocurate. Because the surace has a groove, it is more convenient to remove thewasle sik wiih a small sick when the roler is entangled wiih silk.

Composile roller - The inside is a common sleel pipe, and the outer layer is covered wih a layer olstainless sleel afler. The composite roller is slghily lower in cost than the other two kinds of rollers. and it is an eoonomical and practical choioe.

The transmission mode of the above three of rolers is divided into full servo electronic transmission(wih more precise slrelching ratio) and sprocket transmission.

Spandex self-slop device - When the long and spandex silk are broken, the coarseyam is still fed, resulting in waste yam and a large amount of B-level cotton (the waste sik and longsilk the fine yam return air box cannot be reused). This device will auto-stop fed the spandex andyam.

The self-developed spandex self-stop device of our compamy is different from the commonHoare type detection device (detecting the rotation of the guide wheel), which does not increase orchange the onginal guide wheel (there is an eror when detecting double silk . it adopts an activelaser type spandex detection device. The detection device is instaled in front of the spandex sik cakeand a spandex silk lifing device is installed under the spandex sik cake. The detection device delectswhether the spandex sik is continuously making left and right reciprocating swing motion. When abreak occurs, the spandex lifting device will lit the spandex cake to stop the spandex sik feeding
