preparation example Construction

[0027] The preparation method of above-mentioned flame-retardant comfortable fabric, comprises the following steps:

[0028] Step 1: Spin the hemp fiber into pure hemp yarn with a fineness of 145-200dtex; or, mix the hemp fiber with other fibers, then comb and draw and twist to obtain a hemp blend with a fineness of 98-295dtex yarn;

[0029] Hemp blended yarn is composed of 60-90% hemp fiber and 10-40% other fibers according to the mass percentage, the sum of the mass percentages of the above components is 100%, and other fibers are cotton fiber, viscose fiber, bamboo fiber, Tencel Any at least one of fibers and modal fibers;

[0030] Step 2: spinning poly-m-phenylene isophthalamide into meta-aramid yarn with a fineness of 167-290 dtex; the meta-aramid yarn is meta-aramid filament yarn or meta-aramid staple fiber yarn;

[0031] Step 3: Arrange the meta-aramid yarn obtained in step 2 as warp yarn, the pure hemp yarn or hemp blended yarn obtained in step 1, and the meta-arami...

Embodiment 1

[0035] Step 1: using a spinning process to prepare hemp / cotton blended yarn with a fineness specification of 295dtex, wherein the mass percentage of hemp fiber is 60%;

[0036] Step 2: using a spinning process to prepare meta-aramid staple fiber yarn with a fineness specification of 290dtex;

[0037] Step 3: Arrange the hemp / cotton blended yarn and the meta-aramid staple fiber yarn at a mass ratio of 1:0.75 as the weft yarn, and the meta-aramid staple fiber yarn as the warp yarn, and arrange the warp yarn and the weft yarn in a satin weave Weaving to obtain a flame-resistant comfortable fabric, wherein the arrangement density of warp yarns is 395 / 10cm, the arrangement density of weft yarns is 290 / 10cm, and the mass ratio of hemp / cotton blended yarns to the sum of meta-aramid staple yarns is 1:2.5 .

[0038] Tested according to GB / T5455-1997 "Vertical Method of Textile Combustion Performance Test", the results show that the damage length in both warp and weft directions reache...

Embodiment 2

[0043] Step 1: using the spinning process to prepare pure hemp yarn with a fineness specification of 167dtex;

[0044] Step 2: using a spinning process to prepare meta-aramid filament yarn with a fineness specification of 200dtex;

[0045] Step 3: arrange the pure hemp yarn and the meta-aramid filament yarn in a mass ratio of 1:2.5 as the weft yarn, and the meta-aramid filament yarn as the warp yarn, and weave the warp yarn and the weft yarn according to the satin weave to obtain Flame-retardant comfortable fabric, in which the arrangement density of warp yarns is 410 yarns / 10cm, the arrangement density of weft yarns is 300 yarns / 10cm, and the mass ratio of pure hemp yarns to the sum of meta-aramid filament yarns is 1:6.

[0046] Tested according to GB / T5455-1997 "Vertical Method of Textile Combustion Performance Test", the results show that the damage length in both warp and weft directions reaches 40mm; the afterburning time is 2s in warp direction and 2s in weft direction; ...

Abstract

The invention discloses inflaming retarding comfortable fabric. The inflaming retarding comfortable fabric is satin weave fabric woven by warp and weft. The warp is meta-position aramid yarn, and the weft is composed of pure hemp yarn or hemp blended yarn and meta-position aramid yarn according to the mass ratio of 1: 0.4-2.5; or the warp is composed of pure hemp yarn or hemp blended yarn and meta-position aramid yarn according to the mass ratio of 1: 0.4-2.5, and the weft is meta-position aramid yarn; the total mass ratio of the pure hemp yarn or the hemp blended yarn to the meta-position aramid yarn in the fabric is 1: 1.8-6. A preparing method comprises the steps of weaving the pure hemp yarn or the hemp blended yarn, weaving the meta-position aramid yarn, and interweaving the pure hemp yarn or the hemp blended yarn and the meta-position aramid yarn into the satin weave fabric, and then the inflaming retarding comfortable fabric is formed. The inflaming retarding comfortable fabric solves the problems that existing inflaming retarding comfortable fabric is not durable in inflaming retarding effect and poor in comfort performance, has the advantages of being fire resistant, comfortable, economical, friendly to the environment and attractive in appearance, and has the very good actual significance and development prospects.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, and relates to a flame-retardant comfortable fabric, and also relates to a preparation method of the fabric. Background technique [0002] According to the analysis of fire investigation results, in the past ten years in my country, there have been an average of 30,000 to 40,000 fires every year, with 2,000 to 3,000 deaths, and fire losses equivalent to 200 to 300 million yuan, of which fires caused by textiles accounted for more than half. Tests on indoor fires show that flame-retardant fabrics allow longer escape time (increased by 10-15 times), and the heat released by combustion is only 25% of that of non-flame-retardant fabrics, which can reduce the loss caused by fire by half. Compared with non-flame-retardant fabrics, the toxic gas released by combustion is only 1 / 3 of the latter, and does not produce violent smoke. [0003] There are generally two ways to impart flame-retardan...
