Embodiment Construction

[0024] The invention is a method for improving the light fastness of flame-retardant knitted fabrics, the main steps of which are as follows:

[0025] Step 1, dyeing; dyeing the knitted fabric lightly; when dyeing the knitted fabric, the preferred dyeing depth is 2%-5%, that is, the dyeing depth is only dyed to 95%-98% of the predetermined depth. Dyeing is carried out in an overflow dyeing machine, using dyes, and the process is as follows: reactive red DES, reactive golden DES, sodium sulfate, soda ash. First, homogenize the dye with hot water at 60 degrees and enter the overflow machine for 15 minutes, then add sodium sulfate and soda ash in 3 times, rise to 60 degrees at 0, 8 degrees per minute and dye for 60 minutes, wash with water .

[0026] Step 2, flame retardant finishing; the knitted fabric in step 1 is subjected to flame retardant finishing according to the normal process, so that the flame retardant knitted fabric can meet the fireproof and flame retardant functio...

Abstract

The invention provides a method for improving the light fastness of flame-retardant knitted fabrics, which effectively solves the problems of low light fastness and serious fading of traditional flame-retardant knitted fabrics. It includes the following steps: Step 1, dyeing; dyeing the knitted fabric lightly; Step 2, flame-retardant finishing; performing flame-retardant finishing on the knitted fabric in step 1 according to the normal process, so that the knitted fabric is endowed with fireproof and flame-retardant functions; Step 3, Padding and rolling treatment; the knitted fabric after flame retardant finishing in step 2 is subjected to padding and rolling treatment with live dyes, penetrants and dyeing catalysts; step 4, stacking; step 5, washing; step 4 The flame-retardant knitted fabric that has been piled up for a long time is washed in the overflow dyeing machine to wash away excess dyes and auxiliaries, and the fabric of the flame-retardant knitted fabric is retracted; step 6, setting and drying; step 7, padding again; Use the formaldehyde-free color-fixing agent to pad the flame-retardant knitted fabric after setting and drying in step six; further increase the fastness; step eight, test and compare; the effect of this method is obvious.

Description

technical field [0001] The invention relates to the technical field of sun exposure of knitted fabrics, in particular to a method for improving the light fastness of flame-retardant knitted fabrics. Background technique [0002] Knitted products dyed with reactive dyes have excellent fireproof function after flame retardant finishing, which greatly improves the garment application field of knitted fabrics. However, due to the existence of flame retardants on the fibers, the structure of reactive dyes changes, which intensifies the phenomenon of reactive dyes breaking and discoloring and fading under the action of light, so that the light fastness of flame-retardant knitted fabrics becomes lower. very low. As long as it is slightly exposed to light, it will fade seriously, especially for outerwear and jersey products. This kind of product has a poor wearing environment and is exposed to sunlight, which requires higher sun exposure. [0003] The light fastness of dyed knitte...
