Embodiment 1

[0044] The selected cotton / nylon blended fabric is cotton / nylon 6 blended fabric, and the weight per square meter of the fabric is 273g / m 2 . In this blended fabric, the content of nylon 6 is 45%, and the content of cotton is 55%.

[0045] The first bath finishing liquid is: tetrahydroxymethyl phosphonium salt and urea initial contraction (THPC-U) 308g / L, N-hydroxymethyl-3-(dimethoxyphosphono)propionamide (Pyrovatex CP) 62g / L, flame retardant DM-3070107g / L, cyclic phosphate ester 33g / L, N-methylolacrylamide 31g / L, urea 88g / L, polysiloxane emulsion 30g / L, nitro-p-toluene Sodium sulfonate 55g / L. The first-bath finishing solution was applied to the above-mentioned cotton / nylon blended fabric by padding, dried at 100° C., and baked at 160° C. for 2.5 minutes.

[0046] The second bath finishing solution is: tetrahydroxymethyl phosphonium salt and ammonia precondensate (THPN) 234g / L, flame retardant DM-307092g / L, cyclic phosphate (that is, bicyclic phosphite and phosphonate conde...

Embodiment 2

[0055] The selected cotton / nylon blended fabric is cotton / nylon 66 blended fabric, and the weight per square meter of the fabric is 298g / m 2 . In this blended fabric, the content of nylon 66 is 65%, and the content of cotton is 35%.

[0056] The first bath finishing solution is: pre-condensed product of tetrahydroxymethyl phosphonium salt and ammonia (THPN) 315g / L, tetrahydroxymethyl phosphonium salt (THPC) 55g / L, flame retardant DM-307090g / L, cyclic Phosphate ester 20g / L, N-methylolacrylamide 25g / L, urea 62g / L, polysiloxane emulsion 30g / L, sodium nitro-p-toluenesulfonate 50g / L. The first-bath finishing solution was applied to the above-mentioned cotton / nylon blended fabric by padding, dried at 100° C., and baked at 160° C. for 2.5 minutes.

Abstract

The invention provides a cotton / nylon blended fabric endurable and fire resistant finishing method and a staining method. The finishing method comprises the following steps: (1) adopting initial bath finishing liquor to perform pad-roll treatment on a cotton / nylon blended fabric, wherein the initial bath finishing liquor comprises at least one type of phosphorus-containing compound, at least one type of nitrogen-containing compound, at least one type of softening agent and at least one type of oxidizing agent; (2) adopting second bath finishing liquor to perform pad-roll treatment on the cotton / nylon blended fabric subjected to the treatment of the initial bath finishing liquor, wherein the second bath finishing liquor comprises at least one type of phosphorus-containing compound, at least one type of nitrogen-containing compound and at least one type of cross-linking agent; (3) adopting third bath finishing liquor to perform pad-roll treatment on the cotton / nylon blended fabric subjected to the treatment of the second bath finishing liquor, wherein the third bath finishing liquor comprises at least one type of oxidizing agent, at least one type of formaldehyde catcher and at least one type of softening agent. The method has the advantages of enabling the fabric to have excellent endurance and fire resistance, comfort hand feeling, and good color consistence.

Description

technical field [0001] The invention relates to the field of finishing and dyeing of cotton / nylon blended fabrics, in particular to a durable fireproof finishing method and dyeing method of cotton / nylon blended fabrics. Background technique [0002] Cotton / nylon blended fabric has both the excellent properties of nylon and cotton, not only has a strong body, but also has the characteristics of wear resistance, good elasticity, and full hand feeling. It is an ideal fabric for making various men's and women's clothing, especially military clothing. The durable fireproof finishing of cotton / nylon blended fabric can make it have good protection performance and broaden the application field of the fabric. [0003] The traditional process is generally to dye cotton / nylon blended fabrics, and then perform fireproof finishing. However, due to the addition of fire-resistant finishing agents, the color of the dyed blended fabric will change to a certain extent, which will affect the ...
