Embodiment 2

[0059] The manufacture method of wet-coated flame-retardant nylon label tape comprises the following steps in sequence:

[0060]Base fabric pre-treatment: pre-treatment includes desizing and heat setting; desizing means desizing the base fabric and treating it in a desizing solution at a temperature of 100°C; the desizing solution consists of 2-5g / L chelating dispersant, 5g / L refining agent.

[0061] Heat setting is to soak the desized base fabric with water-based flame retardant at a temperature of 180°C and bake it for 30s; The base fabric is dipped with water-based flame retardant, so that the inside of the yarn is first coated with a layer of flame retardant glue.

[0062] Sizing material preparation: the component of sizing material is made up of following parts by weight:

[0063] Methanol 60 parts

[0064] Calcium chloride 30 parts

[0065] 20 parts polycaprolactam

[0066] 10 parts of melamine resin flame retardant

[0067] Antistatic agent 2 parts

[0068] 0.1...

Embodiment 3

[0072] The manufacture method of wet-coated flame-retardant nylon label tape comprises the following steps in sequence:

[0073] Base fabric pre-treatment: pre-treatment includes desizing and heat setting; desizing means desizing the base fabric and treating it in a desizing solution at a temperature of 95°C; the desizing solution consists of liquid alkali with a concentration of 12g / L, 4g / L The composition of the chelating dispersant and 3g / L refining agent.

[0074] Heat setting is to soak the desized base fabric with water-based flame retardant at a temperature of 160°C and bake it for 25 seconds; The base fabric is dipped with water-based flame retardant, so that the inside of the yarn is first coated with a layer of flame retardant glue.

[0075] Sizing material preparation: the component of sizing material is made up of following parts by weight:

[0076] Methanol 50 parts

[0077] Calcium chloride 25 parts

[0078] 15 parts polycaprolactam

[0079] 8 parts of melam...

Abstract

The invention relates to label cloth and a manufacturing method thereof, in particular to flame-retardant nylon label cloth which is provided with wet-process glued layers and can be used for thermal transfer printing and a manufacturing method thereof. The flame-retardant nylon label cloth comprises a base cloth layer as well as an upper flame-retardant layer and a lower flame-retardant layer applied to upper and lower surfaces of the base cloth layer, wherein the base cloth layer adopts nylon cloth having a flame-retardant function, the total thickness of the base cloth layer and the flame-retardant layers ranges from 0.120 mm to 0.140 mm, and the weight ranges from 75 g / m<2> to 85 g <2>; and each flame-retardant layer comprises a sizing material formed by a halogen-free flame retardant, nylon resin and an antistatic agent. The manufacturing method comprises the following steps in sequence: pretreatment of the base cloth: the pretreatment comprises desizing and heat setting; preparation of the sizing material: the sizing material comprises components in parts by weight as follows: 40-60 parts of methanol, 20-30 parts of calcium chloride, 8-20 parts of polycaprolactam, 5-10 parts of the flame retardant, 1-2 parts of the antistatic agent and 0.06-0.1 part of a brightening agent; wet process gluing: the base cloth after the pretreatment is dipped in the sizing material for gluing, wherein the temperature of the sizing material ranges from 35 DEG C to 50 DEG C, and the viscosity of the sizing material ranges from 1,500 cps to 3,000 cps. According to the label cloth, the flame-retardant layers are soft in texture, and the flame-retardant effect can meet FMVSS (federal motor vehicle safety standard) 302 standard.

Description

technical field [0001] The invention relates to a trademark tape and a manufacturing method thereof, in particular to a wet-coated flame-retardant nylon trademark tape which can be used for thermal transfer printing and a manufacturing method thereof. Background technique [0002] As an accessory industry in the apparel industry - trademark belts also have their diversification and different needs. When the existing synthetic fiber nylon trademark is used on the car seat belt, it is necessary to prevent the fire from being accidentally caught, effectively stop the open flame from continuing to burn, and reduce the tendency of accidental expansion. Therefore, it is necessary to develop a synthetic fiber nylon trademark belt that can effectively block the fire. Open up markets and a competitive force for businesses. Although there are many flame-retardant products on the market, as a trademark tape industry, the products must not only have flame-retardant effects, but also ha...
