Problems solved by technology

Among them, there are many skein dyeing processes and low production efficiency; the dyeing of package yarns is mostly dyed by dyeing machines.
In the existing dyeing process, when the yarn is to be dyed, the yarn is wound on the loose bobbin and made into a cheese form, and the yarn is dyed in the state of being wound into a cheese form. If the linear density is too high, the dyeing will be uneven, not easy to dye through, and the elasticity of the yarn will be damaged

Abstract

The invention discloses a yarn expanding method and yarn expanding equipment. The yarn expanding equipment comprises a plurality of uniformly distributed inserts, and is characterized by further comprising a fixing plate for hinging one ends of the inserts, a pushing body for pushing the other ends of the inserts outwards, and a pushing plate reciprocating along the length direction of the inserts, wherein a guide hole is formed in the pushing body; a positioning rod is movably arranged inside the guide hole. Through separation of a yarn coil from a loose tube, the yarn coil is in a relaxed state, and an enough gap is formed in the yarn coil for dyeing liquid to enter the yarn coil to thoroughly dye the yarn coil, so that the yarn coil is small in density and uniform in dyeing and the defect that use of the loose tube is continued during dyeing is avoided; meanwhile, the yarn coil is in the relaxed state, so that the yarn coil is avoided from being in a tight state for a long time andthe elasticity of a spandex yarn is avoided from being damaged.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a yarn expanding method and equipment. Background technique [0002] Currently, dyeing methods for yarns containing elastic fibers generally include: strand dyeing and cylinder dyeing. Among them, there are many skein dyeing processes and low production efficiency; the dyeing of package yarns is mostly dyed by dyeing machines. In the existing dyeing process, when the yarn is to be dyed, the yarn is wound on the loose bobbin and made into a cheese form, and the yarn is dyed in the state of being wound into a cheese form. If the linear density is too large, the dyeing will be uneven, difficult to dye through, and the elasticity of the yarn will be damaged. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems in the prior art, and provide a yarn expanding method and equipment, which can separate loose tubes ...
