Abstract
A frame-retarding fabric used to make labour-protecting products including glooves, clothes, shoe cover, cap, apron and oversleeves is made of pre-oxidized fibre through dividing, cyclization, cutting, carding, making sliver, spinning and weaving. Its advantages are high flame-retarding effect, high durability and low cost.
Description
The present invention relates to a kind of textiles, be used for the fire-retardant weaving labour protection goods and the production technology thereof of high-temperature operation occasion.
At workroom in high temperature, high temperature resistant, anti-burning to the labour protection product requirement that labourer wears, have fire resistance.Present used fire-retardant labour protection goods, multiselect soaks fire retardant with general lining and makes, and its shortcoming is that flame retarding process complexity, contaminated environment, fire-retardant product are not washable, and flame retardant effect is poor.
Main purpose of the present invention is to provide a kind of labour-protecting appliances of flame-retarding fabric that adopts the high fiber of fire resistance to make good flame retardation effect at above-mentioned deficiency, another object of the present invention provides a kind of new technology, and being used for the high big bunch fiber of fire resistance is the labour-protecting appliances of flame-retarding fabric technology of raw material, production good flame retardation effect.
The present invention is achieved in that it is that raw material is formed by weaving that labour-protecting appliances of flame-retarding fabric adopts polypropylene nitrile carbon precursor or the pure pre-oxidized fibers of pitch base carbon precursor.When raw material specification is 1K～12K, can directly weave, but the cost height.For reducing cost, (40K～320K) is raw material can to adopt the big tow of low-cost pure pre-oxidized fibers, but this raw material should not directly be weaved, need carry out special treatment, its production technology is: with the pure pre-oxidized fibers of big tow is raw material, through a minute silk, bail processing, cut-out, carding, beat bar, spin, be formed by weaving.The bail processing intent is to improve big tow overlap joint ability, realizes weaving.Labour-protecting appliances of flame-retarding fabric is meant that with polypropylene nitrile carbon precursor or the pure pre-oxidized fibers of pitch base carbon precursor be the gloves that raw material weaves, and is made into cloth and clothes of makeing, footwear lid, cap, apron, oversleeve or the like.
Advantage of the present invention is: 1, good flame retardation effect.Adopting high polypropylene nitrile carbon precursor of oxygen index (OI) or the pure pre-oxidized fibers of pitch base carbon precursor first is that raw material is woven into the labour protection goods, can reach fire-retardant requirement without fire retardant, and good flame retardation effect.Labour protection goods flame-retardant standard requires oxygen index (OI) (LOI) at 28-30, and the LOI of pure pre-oxidized fibers is between 45-55, the fire resistance height.2, fire-retardant durable.It is fire-retardant to utilize raw material self anti-flammability to reach goods, after the washing, does not reduce flame retardant effect.3, cost is low.Adopt technology of the present invention, can utilize the big tow of pure pre-oxidized fibers to be raw material, reduce cost at least 75%.About 220,000 yuan per ton of the pure pre-oxidized fibers of 1K, per ton about 80,000 yuan of 3K, per ton about 4.3 ten thousand yuan of 6K, and only about 1.3 ten thousand yuan per ton of the big tow of pure pre-oxidized fibers.
Below in conjunction with embodiment the present invention is described in further detail:
Embodiment 1:
Fire-retardant gloves: the pure pre-oxygen fiber that with the specification is 3K is a raw material, and the braiding of gloves braid method forms routinely.
Embodiment 2:
Flame-resistant garment: the pure zirconia fiber that with the specification is 3K is a raw material, is made into cloth, makes flame-resistant garment.
Embodiment 3:
Fire-retardant gloves production technology:
(1) select materials: selecting specification for use is the pure pre-oxidized fibers of polypropylene nitrile carbon precursor of 240K.
(2) divide silk: with specification is that the pure pre-oxidized fibers of 240K is divided into the 3K specification.
(3) bail processing: will divide fibrage slabbing or tubular behind the silk, and, be about to braided fabric and place in the hot stove (as box type heater) then through high-temperature shaping, Control for Kiln Temperature is at 200-450 ℃, and the time is 20-60min, heat-treats, take apart more at last, can form curved fiber.For preventing the fiber burning, in stove, can add the N2 protection.
(4) cut off: it is long that the curved fiber that will take apart is cut into 78-120mm, so that carding.
(5) carding routinely, beat bar, spin, be woven into gloves.
Embodiment 4:
The flame-resistant garment production technology:
(1) presses embodiment 3 technologies with the big tow spun yarn of pure pre-oxidized fibers.
(2) weaving process is woven into fire-retardant cloth routinely.
(3) make the flame-resistant garment of various styles.
Claims (5)
1, a kind of labour-protecting appliances of flame-retarding fabric, it is characterized in that adopting polypropylene nitrile carbon precursor or the pure pre-oxidized fibers of pitch base carbon precursor is that raw material is formed by weaving.
2, the production technology of the described labour-protecting appliances of flame-retarding fabric of a kind of production claim 1 is characterized in that with the pure pre-oxidized fibers of big tow be raw material, through a minute silk, bail processing, cut-out, carding, beat bar, spin, be formed by weaving.
3, according to the described labour-protecting appliances of flame-retarding fabric production technology of claim 2, it is characterized in that described bail processing is with fibrage slabbing or tubular behind minute silk, then through high-temperature shaping, take apart more at last, can form curved fiber.
4, according to the described labour-protecting appliances of flame-retarding fabric production technology of claim 3, it is characterized in that described high-temperature shaping is that braided fabric is placed in the hot stove, temperature is at 200-450 ℃, and the time, 20-60min heat-treated.
5,, it is characterized in that described labour protection goods are gloves, are woven into clothes, footwear lid, cap, apron, oversleeve that cloth is made according to the arbitrary described labour-protecting appliances of flame-retarding fabric of claim 1 to 4.
