Benefits of technology

[0009]2. The fireproof knitting fabric of the present invention provides a soft and light-weight interior lining, allowing people to wear comfortably without feeling any burden.
[0010]3. The fireproof knitting fabric of the present invention provides an exterior layer made by interweaving the oxidized PAN yarn and the flame retardant fiber, so its mechanical strength can be reinforced.

Problems solved by technology

Conventional process for manufacturing fireproof knitting fabric is to carburize yarn to form a layer of fireproof material on the surface of the yarn, but the carburized yarn is too fragile and easily broken.
However, the obtained flame retardant fabric is not soft enough to be a wearable cloth, and the disclosed adhesive is not fireproof so it might be melted at high temperature which leads to the separation of the base layer fabric and the surface material.
However, the manufacturing process of the three-layered fabric is complicated and the obtained fabric is heavily weighted which leads to undesirable inconvenience when a rescue worker wearing clothes made of such fabric is relieving victims of a disaster.

Embodiment Construction

[0016]Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0017]Refer to FIG. 1, the fireproof knitting fabric 1 consists of an interior lining 11 and an exterior layer 12.

[0018]The interior lining 11, as shown in FIG. 2 and FIG. 4, is obtained by interweaving flame retardant fiber 13. The interior lining 11 is featured by not only high flame retardancy, high thermal insulation and high limit oxygen index, but also soft texture and comfortable wear.

[0019]An exterior layer 12 as shown in FIG. 3 is made by oxidizing and carburizing oxidized PAN yarn (O.X.PAN) 14 for obtaining fireproofness and thermal insulation properties, and then interweaving the flame retardant fiber 13 of the interior lining 11 to obtain the exterior layer 12 (as shown in FIG. 4). The obtained fireproof knitting fabric 1 provides very high mechanical property so the flame retardant fiber 13 and the oxidized PAN yarn 14 ca...

Abstract

A fireproof knitting fabric includes an interior lining and an exterior layer. The interior lining is obtained by interweaving flame retardant fiber. The exterior layer is obtained by carburizing oxidized PAN yarn (O.X.PAN) and then interweaving the oxidized PAN yarn and the flame retardant fiber of the interior lining. The obtained fireproof knitting fabric is featured by fireproofness, thermal insulation, light weight, soft and comfortable texture.

Description

BACKGROUND[0001]1. Field of Invention[0002]The present invention relates to a fireproof knitting fabric. More particularly, the present invention relates to a fireproof retardant knitting fabric comprising an interior lining and an exterior layer. The interior lining is obtained by interweaving flame retardant fiber. The exterior layer is obtained by interweaving oxidized PAN yarn (O.X.PAN) and the flame retardant fiber of the interior lining. The obtained fireproof knitting fabric is featured by fireproofness and thermal insulation.[0003]2. Description of Related Art[0004]Fireproof knitting fabric has very wide applications such as fireproof clothing for fireman, military uniform for soldier, protective apparel for chemical experimentalist, and protective apparel for people working at high temperature environment. All of above applications re quire clothes to be fireproof and thermal insulating. Conventional process for manufacturing fireproof knitting fabric is to carburize yarn t...
