Benefits of technology

[0028]First, the flame retardant yarn of the present invention is made by blending flame retardant viscose fiber with superior flame retardance and high tenacity flame retarding fiber, having limiting oxygen index (LOI) no less than 32. However, breaking strength of the flame retardant viscose fiber is around 2.5 cN/dtex which is low and means bad spinnability. The present invention takes advantage of the superior flame retardance of the flame retardant viscose fiber, and takes the flame retardant viscose fiber as a major component to blend with other good tenacity and spinnability fiber such as flame retardant polyester with breaking strength no less than 5.1 cN/dtex. To ensure the requirements for flame retardancy standard are satisfied, the tenacity or breaking strength is enhanced as efficiently as possible through the adjustment of the raw materials proportioning. The flame retardant viscose fiber is 40˜90% by weight of the flame retardant yarn, conforming to the requirements of flame retardancy and tenacity. The higher the weight percentage of the flame retardant viscose fiber is, the higher the LOI or the better the flame-retard

Effect test

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.
