The fabrics/garments/apparel described herein comprise yarns prepared from blends of polymers and woven in stellar weave. The blend of fibers comprises flame retardant viscose fibers, meta aramid fibers, para aramid fibers, Nylon 66 fibers, and antistatic fibers in a predefined proportion. A process of manufacturing the fabric for wearable light weight protective apparel comprises processes of spinning, weaving, wet processing and garmenting carried out in a predefined manner. ## Claims ### Claim at position 1 1-11. (canceled) ### Claim 12 A light weight fabric for flame retardant protective wear, comprising: flame retardant viscose fibers from about 40% to about 60% by weight of total weight of the fabric; meta aramid fibers from about 25% to about 40% by weight of total weight of the fabric; para aramid fibers from about 5% to about 10% by weight of total weight of the fabric; and nylon 66 fibers from about 5% to about 10% by weight of total weight of the fabric. ### Claim 13 (depends on 12) The light weight fabric as claimed in claim 12, further comprising antistatic fibers from about 0.4% to about 3% by weight of total weight of the fabric. ### Claim 14 (depends on 12) The light weight fabric as claimed in claim 12, wherein the fabric less than 5% weight of naturally occurring fibers including cotton, jute and the like based on total weight of the light weight fabric. ### Claim 15 (depends on 13) The light weight fabric as claimed in claim 13, wherein the fabric less than 5% weight of naturally occurring fibers including cotton, jute and the like based on total weight of the light weight fabric. ### Claim 16 (depends on 12) The light weight fabric as claimed in claim 12, wherein the fabric is substantially free of naturally occurring fibers including cotton, jute and the like. ### Claim 17 (depends on 13) The light weight fabric as claimed in claim 13, wherein the fabric is substantially free of naturally occurring fibers including cotton, jute and the like. ### Claim 18 (depends on 12) The light weight fabric as claimed in claim 12, wherein the flame retardant viscose fibers preferably includes rayon fibers. ### Claim 19 (depends on 12) The light weight fabric as claimed in claim 12, wherein the light weight fabric has weight from about 140 GSM to about 250 GSM. ### Claim 20 (depends on 13) The light weight fabric as claimed in claim 13, wherein the light weight fabric has weight from about 140 GSM to about 250 GSM. ### Claim 21 (depends on 12) The light weight fabric as claimed in claim 12, wherein the light weight fabric has yarn count from about 2/44 s Ne to about 2/24 s Ne. ### Claim 22 (depends on 12) The light weight fabric as claimed in claim 12, wherein the fabric is stellar weave. ### Claim 23 A process of manufacturing a light weight fabric for flame retardant protective wear, comprising the steps: spinning the fibers forming yarns wherein said spinning comprising the steps of: treating the fibers in a predetermined ratio in a blow room by opening and blending the fiber in a predetermined ratio; processing the fiber in a carding machine for cleaning the impurities, naps thereby providing an output sliver; passing the fiber through a draw frame for making the fibers parallel for removing hooks; winding of the fibers were carried out to make a bigger package; steaming the fibers to remove a snarling; and parallel winding thereby forming a double yarn; weaving of the yarns wherein said weaving further comprising the steps of: warping the double yarns for making warp sheet for loom processing; sizing the warped double yarn by using a modified starch, a lubricant and a softener for enhancing the weavability of the fiber; and weaving the sized yarns in a predefined pattern on an air jet loom for forming stellar weave fabric; wet processing of the fabric wherein said wet processing further comprising the steps of: singeing of the fabric by burning protruding fibers by singeing machine through a gas burner; desizing the fabric for removal of added impurities; washing the fabric with hot water for removal of impurities; vat dyeing of the fabric through pad dry-pad steam process; developing the fabric on a continuous dyeing range machine by padding with a reducing agent followed by steaming; oxidation of the fabric with H2O2 followed by washing; and drying at a vertical drying range; treating the fabric by a hydrophilic softener on a stenter machine for facilitating soft hand feel to the fabric; and sanforising the treated fabric in length and width for providing the light weight fabric having permanent dimensions. ### Claim 24 (depends on 12) A flame retardant protective wear comprising a light weight fabric as claimed in claim 12. ### Claim 25 (depends on 12) A process for making flame retardant protective wear comprising garmenting of the light weight fabric as claimed in claim 12. ### Claim 26 (depends on 23) A process for making flame retardant protective wear comprising garmenting of the light weight fabric manufactured by a process as claimed in claim 23 wherein said garmenting made with flame retardant trims.
