Embodiment Construction

[0017] The cotton fabric is pretreated by heating and boiling the cotton fabric in 1% NaOH solution for 30 minutes, then washing it with clean water, washing it thoroughly with deionized water, and drying it in an oven at 60°C until it reaches a constant weight. , so as to remove impurities that may affect the flame retardant modification. Add 10% boric acid into distilled water, fully stir in a 60°C water bath, prepare a flame-retardant finishing solution, soak the pretreated cotton fabric in the flame-retardant finishing solution, and perform two dipping and two rolling treatments (paddle Speed ​​2m / min, pressure 0.3MPa, soaking time 20min). The treated fabric was baked in an oven at 150°C for 3 minutes, and then dried at 80°C. The cotton fabric without flame retardant treatment has a damage length of 30cm in the vertical burning test, an oxygen index of only 17.4%, and poor char formation, and the char layer strength is extremely low. Although the damage length of the fla...

Abstract

The invention relates to a method for finishing flame-retardant modified natural cellulose fabric with protein. The selected flame retardant is dissolved in deionized water to make a flame retardant finishing solution, and the fabric is treated by two dipping and two rolling methods, and then the protein is dissolved in deionized water to prepare an emulsion with a certain viscosity, and The fabric after the flame-retardant treatment in the previous step is coated, and then placed in an oven for drying. The char-forming property of the fabric after flame-retardant treatment becomes better, and the limiting oxygen index and vertical burning effect are obviously improved. In the GB / T5455‑1997 Textile Combustion Performance Test Vertical Method, it has reached level B1. The invention adopts two dipping, two rolling and coating processes to treat the fabric, and has the advantages of simple process, less equipment investment, and little influence on the mechanical properties of the fabric itself.

Description

technical field [0001] The invention relates to the flame-retardant post-finishing modification of natural cellulose fabrics, which uses a protein-containing flame-retardant formula to post-finish the flame-retardant modified natural cellulose fabrics. [0002] technical background [0003] Natural fibers are textile fibers obtained directly from natural or artificially cultivated plants and artificially raised animals. The natural fibers that exist in nature mainly include cotton, hemp, silk and animal hair. The molecular components of cotton and hemp are mainly cellulose, which belong to natural cellulose fibers, while the molecular components of silk and wool are mainly proteins. [0004] Natural fibers are widely welcomed due to their excellent moisture absorption and breathability properties, good dyeability and ecological relevance, and a wide range of sources. However, natural fibers are flammable fibers, and there is a danger of burning. Fires caused by natural fiber...
