Problems solved by technology

[0005] However, the use of electrostatic layer-by-layer self-assembly technology for flame-retardant post-treatment of polyester fabrics requires the selection of flame retardants for polyester fabrics. Currently, the halogen-free flame retardants used for polyester fabrics are mainly phosphorus-based flame retardants. However, the function of this type of flame retardant to achieve flame retardancy is to promote the melting of polyester fabrics, which cannot have both flame retardancy and anti-melting properties.

preparation example Construction

[0061] Another aspect of the present invention provides a method for preparing a flame-retardant and drip-resistant polyester fabric, preferably the method for preparing a flame-retardant and drip-resistant polyester fabric according to the first aspect of the present invention, the method comprising the following steps:

[0062] Step 1. Pretreating the surface of the polyester fabric;

[0063] According to the present invention, in step 1, the polyester fabric is subjected to surface pretreatment, and the surface pretreatment is to perform surface graft modification treatment on the polyester fabric. Preferably, the graft compound described in the first aspect of the present invention is used to The fabric is surface-grafted.

[0064] According to the present invention, in step 1, the method for pretreating polyester fabric includes:

[0065] Step (1), washing and drying the polyester fabric;

[0066] According to the present invention, in step (1), the polyester fabric is ...

Embodiment 1

[0123] The flame retardant polyester fabric will be washed sequentially with acetone and deionized water and dried;

[0124] Wherein, the flame retardant polyester fabric is prepared by the following method: the flame retardant copolyester is prepared according to the method of Example 3 in Patent Application No. 201210526666.1, and then the flame retardant copolyester is spun at a temperature of 270° C. The yarn speed was 2000 r / min, the fibers after spinning were stretched at 80 °C, the stretching ratio was 3 times, and the setting temperature was 180 °C to obtain flame-retardant polyester fibers. The linear density of the fibers was 2.0 dtex. The ester fiber is woven into a plain knitted fabric to obtain a flame retardant polyester fabric, and the limiting oxygen index of the obtained flame retardant polyester fabric is 35%.

[0125] Add 35g of acetone and 17.5g of water to the container, add 18g of acrylic acid and 4.5g of 1-hydroxycyclohexyl phenyl ketone and mix evenly, ...

Embodiment 2

[0130] The preparation process of Example 1 was repeated, except that 45 g of acetone and 22.5 g of water were added to the container, and 6 g of acrylic acid and 1.5 g of 1-hydroxycyclohexyl phenyl ketone were added and mixed uniformly.

[0131] The graft ratio of the polyester fabric was measured to be 1.30%.

Abstract

The invention discloses a flame-retardant and drip-resistant polyester fabric and a preparation method thereof. The flame-retardant and drip-resistant polyester fabric comprises a base body and a decoration layer, wherein the base body is a polyester fabric, and the decoration layer is decorated on the surface of the base body. The modified layer includes a cation layer and an anion layer, and the anion layer and the cation layer are alternately assembled. The preparation method of the flame-retardant and drip-resistant polyester fabric includes the following steps: step 1, performing surface pretreatment on the polyester fabric; and step 2, performing layer-by-layer self-assembly on the polyester fabric obtained in step 1. The invention adopts the method of graft modification and electrostatic layer-by-layer self-assembly to form a modified layer on the surface of the polyester fabric, endows the polyester fabric with excellent flame retardant and anti-droplet properties, and the preparation method is simple in process, easy to implement, and environmentally friendly. Low pollution.

Description

technical field [0001] The invention relates to a flame-retardant fabric, in particular to a flame-retardant and drip-resistant polyester fabric and a preparation method thereof. Background technique [0002] Polyester fabrics have excellent comprehensive properties. For example, the commonly used polyethylene terephthalate (PET) fabrics have the advantages of high modulus, high strength and shrinkage resistance, and are widely used in textile materials and decorative fabrics. Polyester fabrics are flammable and will drip after burning, causing irreparable damage to personal and property safety, which limits the application of polyester fabrics in military uniforms and protective clothing. Therefore, domestic researchers have been working on the flame retardant research of polyester fabrics. [0003] At present, the flame retardant modification of polyester fabrics includes flame retardant modification of the raw yarns of polyester fabrics and flame retardant post-treatment...
