Definitions
- the present invention relates to the field of technical textiles and more particularly, textiles which have, on the one hand, a remarkable inertia a large number of reagents and, on the other hand, excellent resistance to heat. It relates more specifically to a manufacturing process of cross-linked polyacrylate fire-resistant fibers.
- Polyacrylate fibers are known for their excellent fire characteristics and their resistance not only to the action of heat but also to that of chemicals.
- Such polyacrylate fibers have been used in the production a fireproof textile barrier including FR-2.602.429.
- Such fibers are proposed by the company COURTAULDS under the name INIDEX®.
- the polyacrylate fibers proposed are necessarily in the form of wadded tablecloths or needles, of non-woven type, since their technical characteristics are not not allow them to be spun by conventional techniques of spinning.
- the aim of the present invention is to propose a method of manufacture of polyacrylate fibers that is not based on a co-polymer crosslinked acrylic acid and acrylamide.
- the second object of the present invention is to propose a method of manufacture of polyacrylate fibers whose technical characteristics are such that they can be spun by conventional spinning techniques.
- the operating conditions are such that the titration of the fibers treated is at least 1.5 times the titration of the starting fibers.
- the temperature is of the order of 105 ° C.
- Acrylic fiber cable that is processed according to the different stages mentioned above is a standard cable, ie a cable that has not been subjected to prior transformations and which is conventionally implemented for the conventional uses of acrylic fibers, for example in clothing, furniture ....
- the hydrazine-based solution which is implementation in the first crosslinking step is a hydrate solution of hydrazine and the corresponding stage has a duration of the order of three hundred sixty minutes at the determined temperature, between 100 and 120 ° C and preferably of the order of 105 ° C.
- the soda solution that is used in the second hydrolysis step is a 4% sodium hydroxide solution and the corresponding step has a duration of the order of one hundred and twenty minutes to one temperature of the order of 90 ° C.
- the acid solution that is used in the third neutralization step is a 5% sulfuric acid solution and the corresponding third step has a duration of the order of thirty minutes to a temperature of the order of 60 ° C.
- the metal salt solution which is used implemented in the fourth step is a solution of zinc acetate 6% zinc by weight relative to the weight of fibers.
- this fourth step has a duration of the order of sixty minutes at a temperature of the order of 100 ° C.
- the cross-linked polyacrylate fiber cable which is obtained by the process of the invention is pink, being a solution of zinc salt during the fourth step.
- the operating conditions are determined so that the Titration of the treated fibers is in the order of 1.8 to 2.6 times the titration of the fibers of departure.
- the crosslinked polyacrylate fibers obtained by the above process, may have a toughness greater than 15 cN / tex and an elongation greater than 30%, which makes them particularly suitable to be transformed into yarns by conventional spinning techniques.
- these fibers have average thermal conductivity of 45 mW / m ° C, a calorific value average of 4500 Kcal / kg and an average temperature of auto-flammability (at 100% oxygen) at 435 ° C.
- the starting material is in the form of a fiber rope acrylic products as proposed on the market, for example under the name LEACRYL®, DRALON®, COURTELLE® ....
- the cable is loaded in the holders; he is compressed to get uniformity of the desired density, then the material carriers are introduced into the autoclave.
- the autoclave is filled with a hydrazine hydrate solution at 10% at a temperature of 20 ° C. Temperature the solution is gradually brought to 105 ° C where it is kept about three hours. The solution is then cooled and emptied from the autoclave. After this first crosslinking step, involves rinsing with hot water to remove leftover hydrazine hydrate solution that would not have reticle. The autoclave is then emptied of the rinsing water.
- the autoclave is filled with a solution 4% sodium hydroxide. This solution is brought to a temperature of the order of 95 ° C and is maintained at this temperature for a period of the order of two hours. It is then cooled and removed from the autoclave. After this second step involves a hot rinse so as to eliminate the leftover sodium hydroxide solution that has not reacted during the step hydrolysis.
- the autoclave is filled with a solution of sulfuric acid at 5%. This solution is brought to a temperature of 60 ° C which is maintained for about thirty minutes, before being evacuated of the autoclave.
- a hot rinse remove the remaining sulfuric acid that has not been used for neutralization.
- the autoclave is filled with an acetate solution of zinc and acetic acid.
- concentration of this solution is determined by so that the amount by weight of zinc is of the order of 6% by weight of cable introduced into the autoclave.
- This solution is brought to a temperature of the order of 100 ° C, which temperature is maintained for about an hour before being cooled and removed from the autoclave.
- rinsing with a rinsing solution which may include finishing compounds, especially antistatic, softeners.
- the initial titration is 2.2 dtex and the final titre being 4.87 dtex, the weight loss observed during the test was was 1.43%.
- the resulting fibers have excellent heat resistance; they char without melting, do not shrink, do not emit toxic smoke, are very rich in oxygen and have a remarkable chemical inertness to a large number of reagents.
- the fibers had a titration of 1.3 dtex, the titration of the obtained fibers was 2.29 dtex and had a tenacity of 16.6 cN / tex and an elongation of 37.5% with a initial module of 449 cN / tex.
- the treated fibers have a humidity recovery of about 12% with an absorption rate of around 47%.
- the fibers thus treated do not exhibit any shrinkage with boiling water, can experience thermal shock up to 300 ° C and have a very good resistance to both acids and bases, not soluble in any of the usual solvents.
