Abstract
The invention discloses a flame-retardant viscose staple fiber and a preparation method of the flame-retardant viscose staple fiber. The flame-retardant viscose staple fiber adopts a special production technology, and is a special phosphorus-series viscose fiber for which organic phosphate as an effective component is added before spinning; the flame-retardant viscose staple fiber is produced by adopting technological processes including spinning, refining, drying and the like.
Description
Technical field
The present invention relates to a kind of viscose technical field, relate in particular to a kind of fire retardant viscose short filament and preparation method thereof.
Background technology
Early stage Fire resistant viscose fiber is that the method arranging after adopting is produced.It is after fiber is made or in process of production, with nitrogenous organophosphorus ester compound, fiber is processed, or antimonous oxide and halogen-containing fire retardant are coated in to the surface of fiber with latex state.Flame-retardant fiber effect prepared by this method is better, but the smog that chance fire produces is large, and fiber wash durability is poor, carries out fire resistance in dyeing and finishing process easily sustain damage at fiber.
Various fire resistance fibres both domestic and external, mostly are polyester fiber now, and their advantage is that the physical and mechanical properties of fiber is obviously better than viscose.But the polyesters fire resistance fibre having while there is burning can produce melting drip phenomenon, ignite low ignition point material or scald people, cause spot fire and injury, and some meetings produce a large amount of poison gas, and people is suffocated.
That expert or people recognize such problem now, fire-retardant product majority is the state of " maintain an army for a thousand days and use military forces for the moment ", it is non-ignitable wearing in most times of fireproof clothes, therefore within most time, intensity, comfortableness are most important, if wear this fireproof clothes, to people, bring strong sense of discomfort, dressing person is reluctant to wear certainly so, and this has just lost the meaning of protection; Even without reaching exhausted uncomfortable degree, also can affect operating efficiency; Moreover, if the insufficient strength of fabric also can affect protection effect.Therefore,, for flame retardant textiles, should take into account intensity, comfortable and fire resistance, from economy and protective, consider, primary index that even should be using intensity as fire retardant protective clothing, comfortableness is placed on second, is then only the fire resistance that may use once in a while.
And can there is not melting drip phenomenon, thereby stop secondary injury in Fire resistant viscose fiber direct charing of when burning or solidify.Meanwhile, Fire resistant viscose fiber has better skin-friendly and dyeability than fire-retardant polyester fibre, and regain is in 13% left and right, and this belongs to the regain category that human body sensory is comfortable.With its intrinsic snugness of fit, just can solve the problem that fire-retardant polyester fibre dissolves drippage completely.
, when blend additive process is produced fire resistance fibre, fire retardant joined in viscose glue stoste before spinning, and this just requires not only alkaline-resisting, acidproof, excellent heat resistance of fire retardant, and water insoluble.
Meanwhile, while producing fire resistance fibre, the anti-flammability of fiber has reached standard, and the mechanical performance of fiber has also reduced really, as dry fracture strength does not reach 2.0cN/dtex, will affect like this serviceability of fiber.
Summary of the invention
The present invention fully and comprehensively considers due to the multiple change that adds fire retardant to bring, select the viscose combustion inhibitor special of our company's independent development production and special cellulose viscose manufacturing technique, guarantee to meet under the prerequisite of fire resistance, between many index, try to achieve best overall balance.
First technical problem to be solved by this invention is: use the phosphorus flame retardant of Halogen, this fire retardant is exclusively used in viscose, the patented technology of Qie Weiwo company.Its structural formula is:
Make by the following method:
1, get solvent cyclohexane in stirred vessel, add neopentyl glycol and fully stir, then adding phosphorus thiochloride, keep 40～55 ℃ of temperature fully to dissolve;
2, the mixed liquor that drips solvent triethylamine or cyclohexane and triethylamine, is warming up to 50～65 ℃ of maintenances l.5～2.5 hours;
3, add solvent triethylamine and water, be warming up to 60～75 ℃, keep 8～12 hours;
4, after filtration, grind, obtain the new penta diester fire retardant suspension of a kind of phosphordithiic acid and be used viscose glue combustion inhibitor special.
Use this fire retardant institute production Fire resistant viscose fiber to have permanent fire retardant, limited oxygen index (LOI value) reaches more than 28, meets simultaneously country and the requirement of relevant environmental protection standard in the world;
Second technical problem to be solved by this invention is: by special spinning technique and add the viscose denaturant that relative fire retardant effective content is 10%--20% in fire retardant, guarantee to produce the fire retardant viscose short filament that physical index reaches common viscose staple fibre country Grade A standard.
For solving first technical problem, technical scheme of the present invention is:
