Dye conveying device used for spandex yarn dyeing

Abstract

The invention discloses a dye conveying device used for spandex yarn dyeing. The device comprises a dye vat, a bottom supporting roll and a top extruding roll, wherein the dye vat is used for containing dye, the bottom supporting roll is located at an opening inside the dye vat, and the top extruding roll is located above the bottom supporting roll. Lateral connecting supports are fixedly connected to the inner walls of the two sides of the dye vat respectively through bolts, the bottom supporting roll and the top extruding roll are inserted into connecting through holes in the lateral connecting supports at corresponding positions through rotating shafts on two sides, and movably connected with the lateral connecting supports, a connecting boss which protrudes outwards is arranged on themiddle section of the arc-shaped face of the outer side of the bottom supporting roll, and flow-guiding inclined faces of which either becomes short from the middle section to two sides are arranged at the positions, located on the two sides of the connecting boss, of the arc-shaped face of the outer side of the bottom supporting roll respectively. The dye conveying device has the advantages thatbecause top extruding rings are utilized for extruding yarn in bottom yarn containing grooves, many work steps are omitted, and dyeing efficiency is promoted.

Description

technical field [0001] The invention relates to the technical field of spandex yarn production, in particular to a delivery device for spandex yarn dyeing. Background technique [0002] Spandex yarn is a kind of red elastic fiber, which also belongs to synthetic fiber, medium polyurea fiber, and mid-section polyurea fiber. It is versatile and can be used as swimwear and diapers because of its stretchability; as inner linings for underwear and outerwear because of its resilience; as corsets and pantyhose because of its retention; Strong formability, can be used as outerwear, etc. At present, there are many ways to dye yarn on the market, but the main method is to dye the yarn by coating or soaking directly. However, this dyeing method is not uniform enough for the dyeing of the yarn, and the yarn is easy to absorb water and swell the fuel. It also needs to carry out nesting operation, and the production process is relatively cumbersome and the cost is relatively high. Con...
