Abstract
The invention discloses a blended fabric of polysulfonamide and viscose fiber. The blended fabric of polysulfonamide and viscose fiber is formed by blending and weaving 40wt% to 80wt% of polysulfonamide and 20wt% to 60wt% of viscose fiber. The blended fabric of polysulfonamide and viscose fiber has the advantages that the afterflame time, the smoldering time and the damaged length meet the state standards, and the specified flame retardant requirement is met.
Description
Technical field
The present invention relates to a kind of fabric, relate in particular to the BLENDED FABRIC of a kind of fragrant sulfone synthetic fibre and viscose.
Background technology
Polysulphonamide fiber claims polysulfonamides fibre again, is called for short the PSA fiber, commodity special peace synthetic fibre (TANLON) by name.Virtue sulfone synthetic fibre is a kind of aromatic polyamide fibre with special construction, and formal name used at school is PPSU terephthalamide fiber, this fiber by 4,4 '-diamino-diphenyl sulfone, 3,3 '-condensation polymer of diamino-diphenyl sulfone and paraphthaloyl chloride makes.Polysulphonamide fiber has been introduced benzene structure and sulfuryl when producing, and makes amide groups and sulfuryl interconnect contraposition phenyl and a position phenyl formation linear macromolecule.Since exist on the macromolecular main chain strong electrophilic sulfuryl group-(SO2)-, two keys by phenyl ring are gripped effect altogether, by the system of gripping altogether of phenyl ring, make that the cloud density of nitrogen-atoms significantly reduces on the amide groups, so have outstanding heat-resisting, firing resistance, its long-term serviceability temperature is 250 ℃.The experiment proved that the heat resistance of polysulphonamide fiber, high temperature dimensional stability, chemical resistance, hygroscopicity and dyeability are all comparatively good.The polysulphonamide fiber material is applied to fields such as protective article, high-temperature-resistant filtering material, friction sealed material, electrically insulating material more.
But, the volume resistivity that polysulphonamide fiber is higher and initial modulus, lower coefficient of friction and curling stability, to the spinning of fiber, weave, processing such as dyeing is unfavorable.Subject matter in spinning process shows as: interfibrous cohesive force is less, resultant yarn is difficult, yarn strength is lower, and resultant yarn filoplume is particularly outstanding, and the plumage that becomes mildewed is many, thereby influences yarn quality.
The present invention attempts to improve the performance of polysulphonamide fiber by adopting viscose and polysulphonamide fiber blending.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved by this invention provides the BLENDED FABRIC of a kind of fragrant sulfone synthetic fibre and viscose.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The BLENDED FABRIC of a kind of fragrant sulfone synthetic fibre and viscose is weaved by 40-80wt% virtue sulfone synthetic fibre and 20-60wt% viscose fiber blending and to be formed.
Preferably,
The BLENDED FABRIC of a kind of fragrant sulfone synthetic fibre and viscose is weaved by 50-70wt% virtue sulfone synthetic fibre and 30-50wt% viscose fiber blending.
Described viscose is Fire resistant viscose fiber.
Described Fire resistant viscose fiber, adopt following method to be prepared from: fire retardant is mixed with viscose solution, and wet spinning spray silk technological forming can make described Fire resistant viscose fiber routinely.
Described fire retardant accounts for the quality percentage composition 5-15% of described Fire resistant viscose fiber.
Described viscose solution refers to the sodium hydrate aqueous solution of cellulose sulfonate, and it is the general intermediate raw material of the industry.Preferably, in the described viscose solution, the weight percent content of first fibre is 8-9%, and the weight percent content of NaOH is 4-6%, falling ball viscosity 45-65 second, degree of ripeness 8-16%.
Described fire retardant is N, N '-two (two phenoxy group thiophosphoryl bases) dithiothyldimaide, N-methylol-3-(dimethoxy phosphono) a kind of or its mixture in propionamide and three (2,3-dibromopropyl) the fulminuric acid ester.
Described fire retardant is made up of following components in mass portion: N, N '-two (two phenoxy group thiophosphoryl bases) dithiothyldimaide 20-40 part; N-methylol-3-(dimethoxy phosphono) propionamide 20-40 part; Three (2,3-dibromopropyl) fulminuric acid ester 30-50 part.
Concrete, in the present invention:
Viscose belongs to regenerated celulose fibre.It is one of chemical fibre that drops into the earliest suitability for industrialized production.Because good hygroscopicity, comfortable and easy to wear, spinnability is good, Chang Yumian, hair or various synthetic fiber blending, interweave, for all kinds of clothes and decorative textile product.
Viscose is to extract pure alpha-cellulose (being called pulp) by cellulosic material, handles with caustic soda, carbon disulfide, obtains orange-yellow sodium cellulose xanthate, is dissolved in the diluted sodium hydroxide solution again, becomes the spinning solution of thickness, is called viscose glue.Viscose glue after filtration, after the maturation (placing about 18～30h at a certain temperature, to reduce the esterification degree of cellulose xanthate ester), deaeration, carry out wet spinning, coagulating bath is made up of sulfuric acid, sodium sulphate and zinc sulfate.Sodium cellulose xanthate in the viscose glue and the effect of sulfuric acid in the coagulating bath and decompose, cellulose regenerated and separate out, the gained cellulose fibre becomes viscose after washing, desulfurization, bleaching, drying.
N, N '-two (two phenoxy group thiophosphoryl bases) dithiothyldimaide, molecular formula is as follows:
N-methylol-3-(dimethoxy phosphono) propionamide, the CAS accession number is 20120-33-6, English name: N-hydroxymethyl-3-(dimethoxyphosphonyl) propionamide is abbreviated as provetex CP.
Three (2,3-dibromopropyl) fulminuric acid ester is called for short TBC.Concrete chemical formula: C

Especially, in the present invention, N, N '-two (two phenoxy group thiophosphoryl bases) dithiothyldimaide, the composite use of N_ methylol-3-(dimethoxy phosphono) propionamide and three (2,3-dibromopropyl) fulminuric acid ester, flame retardant effect Synergistic.
With respect to prior art, the marked improvement of technical solution of the present invention mainly is presented as: adopt fragrant sulfone synthetic fibre and viscose fiber blending, make the after flame time of fabric, glow time and char length all meet national standard, reach the fire-retardant requirement of regulation.
The specific embodiment
Be further described below in conjunction with the present invention of embodiment.
Embodiment 1
Take by weighing N, 30 kilograms of N '-two (two phenoxy group thiophosphoryl bases) dithiothyldimaide; N-methylol-3-(dimethoxy phosphono) propionamide is 30 kilograms; 40 kilograms of three (2,3-dibromopropyl) fulminuric acid esters mix and make composite flame-retardant agent.
Above-mentioned composite flame-retardant agent is mixed with viscose solution, and wet spinning spray silk technological forming can make described Fire resistant viscose fiber routinely, and the length of Fire resistant viscose fiber is 38mm.Wherein, the content of fire retardant is 10wt% in the control finished product Fire resistant viscose fiber.
Viscose solution in the described raw material, the weight percent content of first fibre are 8.5%, and the weight percent content of NaOH is 5%, falling ball viscosity 50 seconds, degree of ripeness 12%.
