Problems solved by technology

[0002] Car seat belts have become the primary consideration for drivers and passengers, and are also one of the most important performances of cars. The main production process is warping, weaving and dyeing. Among them, the dyeing process is the most critical to its quality. Because Car seat belts have a certain degree of elasticity, so when dyeing, there are often some quality problems, such as color difference, color spots, water splashes, uneven dyeing, low color fastness, etc. , and more prone to fading, these problems have seriously affected the quality of car seat belts

Abstract

The invention discloses a dying method capable of enhancing dyeing uniformity of an elastic safety belt. The method comprises the following steps of 1, soaking a weaved safety belt into uncoiling liquid, and drying; 2, soaking the dried safety belt into dye liquor for 3-5min, and then squeezing liquid out, wherein a dye liquor squeezing rate is controlled to be 45-55%; 3, stretching the safety belt to 1.5 times longer than the original length, the steaming, washing by water, and drying to acquired a finished product. The dying method capable of enhancing dyeing uniformity of the elastic safety belt provided by the invention is simple in operation method, uniform in dying and free of generating color difference and colored patches, and the dyed safety belt is not prone to fade, so that quality of the safety belt is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of safety belt dyeing, and in particular relates to a dyeing method for improving the dyeing uniformity of elastic safety belts. Background technique [0002] Car seat belts have become the primary consideration for drivers and passengers, and are also one of the most important performances of cars. Its main production process consists of three steps: warping, weaving and dyeing. Among them, the dyeing process has the most critical impact on its quality. Because Car seat belts have a certain degree of elasticity, so when dyeing, there are often some quality problems, such as color difference, color spots, water splashes, uneven dyeing, low color fastness, etc. , It is also more prone to discoloration, and the appearance of these problems seriously affects the quality of car seat belts. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a dyeing method for ...
