Alginate fibre blending flame-resistant garment lining and production method
Technical field
The present invention relates to a kind of alginate fibre blending flame-resistant garment lining and production method.
Background technology
Fire-retardant lining is a kind of of functional fabric, can be widely used in industries such as fire-fighting, military clothes, family are spun, petrochemical industry, aviation, sea-freight, hospital.The processing method of existing fire-retardant lining roughly has two kinds: a kind of is to have flame retardant effect after the surface of fabric adds the fire retardant arrangement; Another kind is with the woven fabric of fire resistance fibre, and present fire resistance fibre generally all is just to have fire resistance after handling through fibre modification.Therefore be necessary to develop a kind of without chemical treatment, fiber itself promptly has the new type of permanent fire-retardant lining of natural essence from fire resistance.
The present invention relates to alginate fibre and aramid fiber, briefly introduce as follows:
1. alginate fibre is a kind of fiber that adopts the material spinning process extracted in the natural seaweed to form, and is a kind of important natural function fiber new material, and it removes has environment-friendly degradable; Comfortable moisture absorption is ventilative, and functions such as antibacterial beneficial skin, the most outstanding characteristic are that it is from flame-retarding characteristic; Alginate fibre just up to 34, exceeds 6 percentage points of international standards at oxygen index (OI) under the situation of any processing, and this makes alginate fibre in air, can not play naked light; Do not produce molten drop during burning; Avoid skin ambustion, Product Safety is very good, has both removed expensive fire retardant from; Do not produce pernicious gas after can as fire proofing in the past, not meeting fire yet, can be described as present optimal weaving fire proofing.But alginate fibre also has the shortcoming of himself, and its not anti-highly basic is wet lower by force, is difficult for colouring, and spinning and weaving process requires high.
2. aramid fiber is a kind of novel high-tech synthetic fiber, and it has good flame-retarding characteristic and chemical-resistant stability, and smokescope is low during the fiber burning, does not produce toxic gas, not fusion, only charing.Soft fluffy, heat-resistant antifriction, intensity is high, steady chemical structure.But aramid fiber elasticity is big, and percentage elongation is high, has been prone to static in the process, not easy dyeing.
3. nylon fibre is powerful high, and ABRASION RESISTANCE is good, anti-ly damages by worms, corrosion-resistant, and elasticity and elastic return property are good, but the nylon fibre gas permeability is poor, is prone to produce static.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the present invention will solve is: a kind of alginate fibre blending flame-resistant garment lining and production method that can keep ecological separately advantage of alginate fibre, aramid fiber, polyamide fibre and conductive fiber and premium properties is provided.
The technical solution adopted for the present invention to solve the technical problems is:
