Abstract

The invention relates to a flame-retardant composite fabric and application thereof. Specifically, the flame-retardant composite fabric is formed by bonding a flame-retardant base fabric and a surface fabric. The flame-retardant composite fabric has the advantages of good flame-retardant performance, excellent hand feeling, environmental protection, stable quality, permanent flame retardance and the like, and overcomes the defects in the original scratch-coating composite process.

Description

Flame-retardant composite fabric and application thereof
Technical Field
The invention belongs to the field of production processes of decorative fabrics, and particularly relates to a flame-retardant composite fabric and a production process and application thereof.
Background
In order to minimize the loss and danger in the event of a fire, various fire-resistant materials have been widely used. Especially, when the house is decorated, people often adopt various home furnishings decorated by flame retardant cloth, such as sofas, wall decorations and the like. In order to enable the home decoration fabric to meet the flame retardant requirements of British standard BS5852 and BS7176, cruise ship IMOpart8, American standard TB113 and national standard GB 8624.
The flame-retardant acrylic fiber fabric is mainly realized in the market by blade-coating thick acrylic fiber gum with a flame-retardant auxiliary agent on the back surface of the fabric. However, the flame-retardant fabric for home decoration processed and formed by adopting the method has the following defects: 1. the gram weight of the acrylic gum colloid of the general flame retardant auxiliary agent is generally 100 g/square or even more, and the specific numerical value is related to the components, the gram weight and the structure of the fabric. After the back glue is coated in a scraping way, the most direct influence is that the hand feeling of the fabric is hard, and the comfort of the final product is influenced. 2. The flame retardant property of the fabric mainly comes from the gum material, the flame retardant property of the gum material comes from the flame retardant added in the gum material, and the environmental protection index of most flame retardants in the market does not reach the standard. 3. The back coating is carried out in the back gluing process in a scraper mode, and in the production process of large goods, the addition of the sizing agent is carried out manually by judging the amount of the materials in the size tank through naked eyes by workers. This process affects the consistency of the grammage of the gum in the final product. The production process can also cause the uniformity of the back glue of the fabric, and finally leads to the stability of the flame retardant effect of the large goods. 4. After the production process of the back adhesive is finished, drying and shaping are carried out, but the back adhesive is thick, so that certain requirements are imposed on the shaping temperature and speed. If the gum is not dried completely, the gum on the back side is adhered to the surface of the fabric in the rolling process, so that inferior fabrics are produced. If the final gum is too dry, it tends to peel off and become harder to handle. However, the way of spreading the back adhesive is not stable, and the drying process performed on the basis of the method is not standard at all, which results in large quality deviation of the final product. 5. The fabric after being glued is not suitable for washing in the market.

In a preferred embodiment, the modified acrylic fiber is obtained by copolymerizing vinyl chloride and acrylonitrile which are flame retardant monomers.
Compared with the fiber before modification, the modified acrylic fiber of the invention improves the Limiting Oxygen Index (LOI), and can form a carbonization layer when being mixed with cotton under the condition of flame retardance, thereby effectively preventing flame from entering the filling material (such as sponge) of furniture.
In a preferred example, the polyacrylonitrile carbon fiber precursor pre-oxidized fiber is obtained by pre-oxidizing polyacrylonitrile carbon fiber precursor in an oxidizing environment at 200-300 ℃.

In the pre-oxidation process, three chemical reactions are mainly carried out, namely dehydrogenation reaction, cyclization reaction and oxidation reaction. The color of the polyacrylonitrile protofilament tow changes from white to black. In the pre-oxidation process of the polyacrylonitrile carbon fiber pre-oxidized fiber, the bulk density of the polyacrylonitrile carbon fiber pre-oxidized fiber is increased along with the increase of a temperature zone and the temperature, and finally the polyacrylonitrile carbon fiber pre-oxidized fiber is in a non-combustible state in the air. In the pre-oxidation process, the polyacrylonitrile carbon fiber precursor is converted into pre-oxidized fiber with a ladder-shaped structure and heat resistance from linear molecular chains.
Compared with the precursor, the polyacrylonitrile carbon fiber precursor pre-oxidized fiber improves the Limiting Oxygen Index (LOI) and ensures that the prepared cloth has a flame retardant effect. The polyacrylonitrile carbon fiber precursor pre-oxidized fiber is not melted at high temperature, and can form a carbonized layer, so that flame can be effectively prevented from entering the filling material (such as sponge) of furniture.
In a preferred embodiment, the surface layer fabric is a fabric with ornamental value but no flame retardant effect. For example, a common home decoration fabric. Such as furniture (e.g., sofa) upholstery, artificial leather, and the like.
In a second aspect, the present invention provides a use of the flame retardant composite fabric of the first aspect, for home decoration.
In a preferred embodiment, the home decoration is a decoration of furniture (such as a sofa) or a wall.
The beneficial effects of the invention include:
1. the invention provides a flame-retardant composite fabric for home decoration. The flame-retardant composite fabric is formed by bonding a flame-retardant base fabric and a surface fabric. The flame-retardant composite fabric has both flame-retardant performance and ornamental performance. Wherein the flame retardant base fabric provides flame retardant properties; the surface cloth provides ornamental performance.
2. The flame-retardant composite fabric disclosed by the invention is more excellent in hand feeling, more environment-friendly and more stable in quality.
The invention is obtained by copolymerizing a flame-retardant monomer of vinyl chloride and acrylonitrile in the preparation process of a polymer by utilizing modified acrylic fibers. And the soft hand feeling of the acrylic fiber is kept, and the permanent flame retardant effect is achieved.
The carbon fiber precursor pre-oxidized fiber is characterized in that the precursor of the carbon fiber is subjected to pre-oxidation reaction in an oxidizing environment at the temperature of 200-300 ℃, so that the carbon fiber precursor pre-oxidized fiber has extremely good limiting oxygen index and extremely good flame retardant property.
Because the raw materials are high in price, the modified raw materials are blended with other fibers under the condition of meeting the requirement of flame retardance, so that the flame retardance is ensured, the cost of the fabric is reduced, and the comfortable hand feeling is provided.
