Problems solved by technology

However, the current smoothing agents are all general-purpose products, which are not developed for the special properties of specific products, so they are poorly targeted
Cotton and linen are yarns with relatively poor softness, and it is difficult to meet the stringent requirements of high-quality life by using existing smoothing agents.

Abstract

The invention relates to the technical field of dyeing auxiliary agents and in particular relates to a dyeing method for cotton and hemp blended yarns. The dyeing method comprises the following steps:after finishing soaping in a dyeing process of the cotton and hemp blended yarns, adding the cotton and hemp blended yarns subjected to the soaping into water, wherein the mass ratio of the water tothe cotton and hemp blended yarns is 6 to 1; then adding a smoothing agent, wherein the mass ratio of the smoothing agent to the water is (1 to 2) to 1000; after adding the smoothing agent, raising the temperature to 45 to 50 DEG C and carrying out heat insulation for 30 to 40min; then naturally cooling to room temprature and discharging and airing, wherein the smoothing agent is prepared from thefollowing components: wool grease, sodium hydrogen phosphate, trimethylolpropane fatty acid ester, dimethylsilanol, paraffin wax, sodium oleoyl amino acid, sodium pyrophosphate, polyethylene glycol,sodium polyacrylate, polyethylene glycol ether, bis(2,3-epoxycyclopentyl)ether and water. According to the dyeing method for the cotton and hemp blended yarns, provided by the invention, the smooth performance of dyed cotton and hemp can be effectively improved, so that the quality of a product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a method for dyeing cotton-linen blended yarn. Background technique [0002] In the prior art, the smoothing agent is generally added in the treatment after the dyeing process, so as to make the yarn more smooth and supple. However, the current smoothing agents are all general-purpose products, which are not developed for the special properties of specific products, so they are poorly targeted. Cotton and linen are yarns with relatively poor softness, and it is difficult to meet the stringent requirements of high-quality life by using existing smoothing agents. Contents of the invention [0003] The object of the present invention is to provide a method for dyeing cotton and linen blended yarns that can effectively improve the smoothness and suppleness in order to solve the deficiencies of the above technologies. [0004] In order to achieve the above object, a kind of dyeing ...
