Description
Technical Field
The invention relates to the field of home decoration fabrics, in particular to a production process of a flame-retardant composite fabric.
background
at present, in order to enable the home decoration fabric to meet the flame retardant requirements of British Standard BS5852 and cruise ship IMOpart8, the flame retardant fabric is mainly realized in the market by blade-coating a heavy acrylic gum with a flame retardant auxiliary agent on the back of the fabric. However, the flame-retardant fabric for home decoration processed and formed in the mode is also under the following limit: 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, while the flame retardant property of the gum material comes from the added flame retardant, 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.
