Yarn supporting device for skein rewinding and elastic yarn thermal shrinkage or expansion processing and yarn dyeing method based on yarn supporting device

Abstract

The invention discloses a low-cost yarn supporting device for skein rewinding, which can accommodate a cone of yarn without yarn messing. The yarn supporting device comprises a main rod, a lower baseis movably arranged at the bottom of the main rod, an avoiding hole for admitting penetration of the main rod is movably arranged in the middle of the lower base, a single lug is arranged on the upperside of the lower base, an upper base is fixedly arranged in the middle of the main rod. a single lug is arranged on the lower side of the upper base, a spring is movably arranged on the main rod between the upper base and the lower base, the single lug inside the upper base is movably connected with one end of a fixed inner supporting plate, the single lug inside the lower base is movably connected with one end of a movable inner supporting plate, the fixed inner supporting plate is hinged to the middle of the movable inner supporting plate, the other end of the fixed inner supporting plateis movably connected with the bottom end of an outer supporting plate, a yarn retaining plate is horizontally and fixedly arranged on the outward side of the outer supporting plate, a sliding groove is formed in the upper part of the outer supporting plate, and the other end of the movable inner supporting plate is slidably connected with the outer supporting plate through the sliding groove. Theinvention also discloses an elastic yarn thermal shrinkage or expansion processing and yarn dyeing method based on the yarn supporting device.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a yarn supporter for skein rewinding. Background technique [0002] There are mainly two ways to wind the winder, the bobbin is turned into a bobbin and the skein is turned into a bobbin. The skein is because the yarn has elasticity, and the skein must be in a relaxed state before it can be dyed and other processing procedures. However, when the skein is poured into a bobbin, it is easy to mess up the yarn and the efficiency is low. When traditional skein yarn is rewound, each skein is about 0.3KG, and when it is rewound into a bobbin, 5-6 skeins are needed to form a bobbin. In the middle, processes such as jointing, yarn changing, and yarn arrangement are required, and the labor cost is relatively large. Adding halfway joints further reduces the quality of the yarn. [0003] In the traditional hank yarn dyeing process, the first step is to shake the yarn to turn the bobbin yarn into ha...

The third step is to rewind the skein into a bobbin, which is convenient for unwinding in the next process. The skein needs to be rewound into a bobbin process, because the high-pressure water flow of the hank during the dyeing process causes the yarn in the hank to be disorderly and disorderly, so This process is labor-intensive and has a lot of loss. The comprehensive cost is more than 1,600 yuan per ton, and 3-4% loss needs to be added.

The total cost above is about 9100 yuan per ton, plus loss cost

[0004] However, if the package yarn is directly used for dyeing, it is difficult to dye the inner yarn evenly because the yarn shrinks when it is heated during dyeing; and if it expands when it is heated, the subsequent yarn will be scattered and the rewinding operation will be difficult.
