Abstract

The invention relates to a dyeing method of non-bobbin elastic fibre cheeses, belonging to the dyeing technical field of elastic fibre cheeses, comprising the steps of: (1) a bobbin loosening procedure; (2) a yarn loosening procedure: taking down dropped bobbins; coating redundant socks bobbin pieces on two ends of a bobbin 1 on cheeses after taking out to warp the cheeses; then separating the bobbin 1 from the cheeses; and finally, putting the cheeses separated from the bobbin 1 in a yarn dyeing tube of a cheese dyeing machine; (3) a dyeing procedure; and (4) a bobbin inverting procedure: putting the dyed cheeses in a dehydrator for dehydrating; taking out the cheeses after the dehydration; coating the cheeses on a bobbin 2; turning over the socks bobbin pieces coated with the cheeses on two ends and plugging in the bobbin 2; and inverting the bobbins on the bobbin inverting machine. The dyeing method of the non-bobbin elastic fibre cheeses in the invention can be used for solving the problems of incompletion in dyeing and dyeing defects in the elastic fibre cheeses, absence of elasticity after the dyeing and the cracking of the bobbins.

Description

technical field [0001] The invention relates to a method for dyeing bobbin-free elastic fiber cheese, and belongs to the technical field of elastic fiber cheese dyeing. Background technique [0002] When the cheese dyeing method and process of cotton and polyester yarns are very mature, there are still many problems in the cheese dyeing of elastic fibers, such as elastic polyester, nylon stretch yarn, nylon core-spun yarn, etc. Dyeing by dyeing method will cause the dyeing to be impermeable, lose elasticity after dyeing, and even cause the bobbin to break. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for dyeing bobbinless elastic fiber bobbins. The dyeing method can solve the problems of impermeable dyeing and broken bobbin, and retain the original elasticity of the fiber after dyeing. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A method for ...
