Benefits of technology

The present invention is about a flame retardant yarn that is made by blending flame retardant viscose fiber and at least one high tenacity flame retarding fiber. Its fabrics, such as mattress covers, have good flame retardancy and elasticity due to the high tenacity of the yarn.

Problems solved by technology

It is extremely flammable and has decomposition temperature of 270° C.˜350° C. and combustion temperature of 320° C.˜350° C. The ordinary viscose fiber fails to meet the flame retardancy standard of textiles.

example 1

[0050]Based on a total weight of the flame retardant yarn, weigh for 90 wt % of flame retardant viscose fiber and 10 wt % of flame retardant polyester, take them into a regular cotton spinning equipment to prepare cotton blended silver. The cotton blended silver is eventually spun into 16 yarn-count knitting yarn by a ring spinning frame.

example 2

[0051]Based on a total weight of the flame retardant yarn, weigh for 80 wt % of flame retardant viscose fiber and 20 wt % of flame retardant polyester, take them into a regular cotton spinning equipment to prepare cotton blended silver. The cotton blended silver is eventually spun into 21 yarn-count knitting yarn by a ring spinning frame.

example 3

[0052]Based on a total weight of the flame retardant yarn, weigh for 75 wt % of flame retardant viscose fiber and 25 wt % of flame retardant polyester, take them into a regular cotton spinning equipment to prepare cotton blended silver. The cotton blended silver is eventually spun into 26 yarn-count knitting yarn by a ring spinning frame.

Abstract

The flame retardant yarn of the present invention is made by blending flame retardant viscose fiber and at least one high tenacity flame retarding fiber, the at least one high tenacity flame retarding fiber is flame retardant polyester or flame retardant finishing viscose fiber, wherein the flame retardant viscose fiber is 40˜90% by weight of the flame retardant yarn. The flame retardant yarn takes advantage of the superior flame retardance of the flame retardant viscose fiber, and takes the flame retardant viscose fiber to blend with other good tenacity and spinnability fiber by adjusting amount of raw materials in reasonable balance and avoiding disadvantages of the raw materials to optimize advantages of the flame retardant viscose fiber such as flame retardancy and tenacity so as to provide the flame retardant viscose fiber with high flame retardancy, long lasting flame retardancy effect, strength and elongation performance and good abrasion resistance. Fabric made by the flame retardant yarn not only has good flame retardancy, but also has good elasticity due to high tenacity of the flame retardant yarn.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention generally relates to a technical field of the textile, and more particularly to a flame retardant yarn.2. Related Art[0002]Strong flame retarding fabrics are mainly applied to home textiles such as mattress, pillowcases, etc. The flame retarding fabrics, on one hand, meet the requirements for flame retardancy standard such as 16CFR1633 U.S. standard for mattress flame retardancy. On another hand, the fabrics have higher fiber strength as well. Conventionally, the flame retarding fabrics are made by blends of glass fiber and viscose fiber and being soaked with flame retardant. However, this technique has defeats. The glass fibers have properties of high thermal resistance, non-flammable form and corrosion resistance but they may cause allergic reaction and even contact dermatitis. The IARC (International Agency for Research on Cancer) of the W.H.O. (World Health Organization) had added the glass fibers in...
