Method of flame-retardant treating blend fabric

Abstract

Disclosed is a method of flame-retardant treating a blend fabric including natural fibers and synthetic fibers to impart flame retardancy to the blend fabric, including treating the fabric with a first flame retardant, primarily tentering the fabric, water-rinsing the primarily tentered fabric, washing the water-rinsed fabric, drying the washed fabric, treating the dried fabric with a second flame retardant, and then secondarily tentering the fabric.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to a method of flame-retardant treating a blend fabric, and more particularly to a method of flame-retardant treating a blend fabric which prevents the flame-retardant material of the flame-retardant treated fabric from being discharged to the outside when washed.[0003]2. Description of the Related Art[0004]In order to prevent fire, the importance of flame-retardant function of fibers was rather early emphasized in the developed countries, and there are strong legal prescriptions for the use of flame-retardant fibers for fiber products used in public facilities, children's night clothes, airplanes, automobile seat covers, etc. Also in Korea, laws related to flame retardancy are being gradually enhanced, like the use of flame-retardant fibers in public facilities such as hotels. Alongside the increase in the flame-retardant fiber market, the demand of flame-retardant fibers is expected to become mu...

AI Technical Summary

Benefits of technology

[0011]Accordingly, the present invention has been made keeping in mind the problems encountered in the related art and an object of the present invention is to provide a method of flame-retardant treating a blend fabric, which may eliminate the separate post-treatment of natural fibers and synthetic fibers thus reducing the manufacturing time and cost, and also which may have superior washing durability so that flame retardancy is maintained uniform even upon several washings.

Problems solved by technology

The pretreatment methods exhibit good durability in terms of flame retardancy but are used only in synthetic fibers, and the use thereof is limited depending on the type of fiber material.

Of the post-treatment methods, the graft polymerization of the flame-retardant material is vinyl monomer graft polymerization for reacting an unsaturated compound of phosphoric acid ester with a carbon group of cellulose, and thus such a chemical radical reaction results in low reactivity with cellulose.

Furthermore, UV rays or electrical rays should be inevitably used, undesirably making it difficult to provide necessary equipment and to achieve industrial production, leading to high costs.

However, the manufacturing of such blend fabric is problematic because the natural fibers and the synthetic fibers are separately post-treated, undesirably increasing the manufacturing time and cost, and also because chemical smells are not completely removed after flame-retardant treatment, making it difficult to manufacture such fabric into a product.
