Description
Technical field：
The present invention relates to technical field of textile processing, and in particular to a kind of fire-retardant, UV resistance line style polyester fabric rear whole
Science and engineering skill.
Background technology：
Terylene, nickname polyester fiber.Polyester fabric, it is that a kind of quite varied chemical fiber garment face is applied in daily life
Material, with intensity height, elasticity is good, heat-resist, thermoplasticity is good, wearability is good, light resistance is good, corrosion resistant advantage, therefore suitable
The outdoor goods such as coat garment, all kinds of case and bag and tent are done in conjunction.But there is also dyeability is poor, hygroscopicity is poor, easy band for polyester fabric
The problem of the defects of electrostatic, weak fire-retardant and ultraviolet resistance, especially easy static electrification, brings very big puzzlement to user.
The defects of polyester fabric can be improved by chemical fibre emulation technology, improve its quality.When synthetic fiber modification technology, i.e.,
Some monomers for being advantageous to improve its performance are added in polyester fiber building-up process, make fiber bulk modified, but this technology is grasped
Make that difficulty is big, cost is high, effect is undesirable, less use.Second, the final finishing technology of polyester fabric, i.e., carried out to polyester fabric
The special process strengthens its fire-retardant and ultraviolet resistance.
At present, fire retardant is divided into halogenated flame retardant and halogen-free flame retardants, and halogenated flame retardant is although cheap, fire resistance
Amount of smoke is big during good but burning, and the hydrogen halide discharged has the corrosivity of height, tends to occur secondary pollution.
Different types of halogen-free flame retardants fire resistance is very different, and after increasing fire retardant addition to improve fire resistance
The decline of mechanical properties of fabric can be caused, so as to influence the synthesis performance of fabric.
At present, screening uv-ray agent is divided into two kinds, and one kind is inorganic ultraviolet reflection agent, and the mechanism of action is mainly to purple
Outside line is reflected and scattered to prevent it from passing through fabric, commonly uses titanium dioxide and zinc oxide；Another kind is organic ultraviolet
Absorbent, mainly there is absorption to ultraviolet, contain hydroxyl in its structure, forming stable hydrogen bond, hydrogen bond chelate ring
Ultraviolet energy is absorbed Deng during and is changed into heat energy dissipation, commonly uses benzophenone and benzotriazole.Above-mentioned two class is purple
Outside line smoke agent for shielding prepares Uvr Protective Fabric by co-blended spinning and afterfinish method, for inorganic ultraviolet reflection agent its
With preventing ultraviolet effect stability difference and the problem of low efficiency, and for organic ultra-violet absorber its have it is certain
Toxicity, be not suitable for contacting with the long-time of human body skin.
