Embodiment 1

[0011] Embodiment 1: the production process steps are as follows:

[0012] 1) Configure cotton fiber flame-retardant coating glue: the component distribution ratio is approximately in parts by weight:

[0013] Water-based polyacrylate 50, intumescent halogen-free composite flame retardant 30, water 50, water-based sealing polyurethane 1, non-ionic surfactant (OP-10) 0.2, thickener (PTF) 0.5, water-based mineral oil defoaming Agent 1.2. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 15︰5︰5): flame retardant synergist (organophosphate, nano-montmorillonite) =25:5. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyacrylate, water-based sealing polyurethane, water-based mineral oil defoamer after emulsification and dispersion, and adjust the pH of the solution with ammonia water to 7~ 9. Then slowly add ...

Embodiment 2

[0017] Embodiment 2: the production process steps are as follows:

[0018] 1) Cotton fiber flame-retardant coating glue is configured, and its component proportions are: water-based polyurethane 80, intumescent halogen-free composite flame retardant 56, water 100, water-based sealing polyurethane 10, non-ionic surfactant (OP-10) 3.0, thickener BJ-100 2.0, water-based silicone 2.0. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 35: 20: 0.5): flame retardant synergist (zinc borate) = 55.5: 0.5. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyurethane, water-based blocked isocyanate, water-based mineral oil defoamer after emulsification and dispersion, adjust the pH of the solution with ammonia water = 7 ~ 9, Then slowly add thickener BJ-100 under stirring, and continue emulsifying and dispersing to obt...

Embodiment 3

[0024] Embodiment 3: the production process steps are as follows:

[0025] 1) Cotton fiber flame-retardant coating glue is configured, and its component proportions are water-based polyurethane 30, water-based polyacrylate 40, intumescent halogen-free composite flame retardant 75, water 80, water-based blocked isocyanate 5, Non-ionic surfactant (OP-10) 1.5, thickener P668 1.2, water-based silicone defoamer 0.5. Among them, the proportion of the composite flame retardant is by weight: basic flame retardant (ammonium polyphosphate: pentaerythritol: melamine = 40: 10: 15): flame retardant synergist (vermiculite, white microcapsule red phosphorus flame retardant) =65:10. The preparation method is to add water, OP-10 to the intumescent halogen-free composite flame retardant, add water-based polyurethane, water-based polyacrylate, water-based blocked isocyanate, water-based mineral oil defoamer after emulsification and dispersion, and adjust the pH of the solution with ammonia wate...

Abstract

The invention provides a manufacturing technique of a wash-resistant and flame-retardant blended fabric. The technique comprises the following steps of: 1) preparing a cotton fiber flame-retardant coating adhesive; 2) coating the coating adhesive obtained in the step 1) on the cotton fiber and carrying out heat setting to the cotton fiber so as to obtain a flame-retardant cotton fiber; 3) preparing a glass fiber flame-retardant coating adhesive; 4) directly coating the coating adhesive obtained in the step 3) on the glass fiber and carrying heat setting on the coating adhesive so as to obtaina flame-retardant glass fiber; and 5) blending one of the flame-retardant cotton fiber obtained in the step 2) and a carbon fiber or the flame-retardant glass fiber obtained in the step 4) and one ofa flame-retardant polyester fiber or a flame-retardant nylon fiber so as to obtain the product of the invention. The manufacturing technique of the wash-resistant and flame-retardant blended fabric, provided by the invention, has the advantages of simple process, low cost, good product permeability, softness as well as good wash resistance and flame retardation. The manufacturing technique of thewash-resistant and flame-retardant blended fabric, provided by the invention, is mainly used for manufacturing products like smoke screens, fire-proof insulated curtains, bedspreads, flame-retardant furniture and the like.

Description

technical field [0001] The invention relates to a production process of a blended fabric, in particular to a production process of a washing-resistant and flame-retardant blended fabric. Background technique [0002] Chinese patent CN101709547A discloses a polyester-cotton blended fabric combustion finishing process. First, a flame retardant is added to the polyester polyester, and after blending, a flame-retardant polyester polyester can be obtained, and the flame-retardant properties of the polyester can be obtained through the spinning process. fiber, blended with cotton fiber to obtain a blended fabric, and then use the cellulase alkaline treatment process to reduce the cotton fiber, so that the cotton fiber is reduced, the fiber is thinner, and the fabric becomes softer. The flame retardant finishing of blended fabrics mainly adopts the process of rolling and baking flame retardant finishing. The padding liquid in the padding and baking flame-retardant finishing proces...
