Description
Technical Field
The invention belongs to the technical field of blended fabrics, and particularly relates to a washable carbonized film melt-drip-free fabric.
Background
After the fabric is burnt, the fabric can be divided into molten drop fabric and non-molten drop fabric according to different forms of combustion products. As is well known, polyester fibers have molten drops after combustion, and natural fibers have no molten drops after combustion and carbonization. The development and production of melt-drip-free fabrics are carried out in many countries internationally, for example, the fabric is free of melt drip by using acrylic fibers in Japan, and the fabric is free of melt drip by using Viron in Europe or China.
The former molten drop-shaped combustion product can be tightly attached to the skin to cause serious secondary damage, which is very dangerous, so that the non-molten drop fabric is used in the industries and occasions of flammable and explosive fire fighting, high-temperature operation, emergency training and the like such as petroleum, chemical engineering, dust and the like.
Secondly, the fabric is also a non-molten drop fabric, and can be further divided into a fly ash non-molten drop fabric and a carbonized film non-molten drop fabric, wherein the combustion ash of the fly ash non-molten drop fabric flies in the air, and although the secondary damage caused by molten drop can not be caused in dangerous occasions such as explosion, fire and the like, the skin can be directly exposed to a high-temperature flame environment.
The latter is relatively good, can be carbonized to form a film, cannot cause secondary damage due to melting and dripping in dangerous occasions such as explosion, fire and the like, and has partial isolation effect on thermal damage of the environment.
On the other hand, the research and development center of the conventional melt-drop-free fabric is mainly placed on the combustion and melt-free effect of the fabric, no attention and breakthrough are paid to the field of melt-drop-free carbonized film-forming fabrics, and the individual carbonized film-forming fabrics can only resist washing for 1-2 times and then lose the combustion, carbonization and film-forming properties.
Chinese patent with patent publication No. CN107177979A and publication No. 2017.09.19 discloses a non-dripping flame-retardant polyester fiber/fabric and a preparation method thereof, and is characterized in that the outer surface of the flame-retardant polyester fiber/fabric is dipped in glue solution containing a flame retardant and a crosslinking agent, and the flame retardant and the crosslinking agent are grafted and introduced on the fabric through electron beam irradiation to form a surface layer material; and steaming by using water vapor, soaping, rinsing and drying to obtain the melt-drip-free flame-retardant polyester fiber/fabric with the weight gain of 5-35%.
However, the non-dripping flame-retardant polyester fiber/fabric disclosed by the invention adopts a large amount of flame retardant to realize a sufficient non-dripping flame-retardant effect, so that the close-fitting wearing experience of the fabric is poor.
And more importantly, the no-droplet effect is just that the fly ash has no droplets, and after the fabric is burnt, the skin is directly exposed, which is still extremely dangerous.
Therefore, in summary, a novel fabric with long-term effective carbonized film-forming molten drop-free function is urgently needed, and the molten drop-free function of the carbonized film-forming fabric after at least a plurality of times of water washing can not be obviously reduced.
Disclosure of Invention
The invention aims to provide a washable carbonized film droplet-free fabric, wherein the blended fiber comprises polyesteramide fiber, cotton fiber and polyester fiber, the content of the polyesteramide fiber is 54.2-62.5wt%, the polyesteramide fiber is prepared by copolymerizing terephthalic acid, dodecanediol and caprolactam, the quantity ratio of ester bonds to amido bonds in the polyesteramide fiber is (10.2-15.5): 1, and the fabric has the characteristics that the carbonized film has no droplet and is not easy to fly ash, and the droplet-free function of the carbonized film is still efficiently maintained after multiple times of washing.
The technical scheme adopted by the invention for solving the problems is as follows: the washable carbonized film melt-drip-free fabric comprises polyesteramide fibers, cotton fibers and polyester fibers, wherein the content of the polyesteramide fibers is 54.2-62.5wt%, the polyesteramide fibers are prepared by copolymerizing terephthalic acid, dodecanediol and caprolactam, and the quantity ratio of ester bonds to amide bonds in the polyesteramide fibers is (10.2-15.5): 1.
In the present invention, polyester fiber, that is, polyester fiber, has a preliminary washing resistance advantage by itself, while cotton fiber, that is, natural fiber, has a preliminary non-dripping advantage by itself, and the applicant has achieved the following two objects by quantitatively introducing polyesteramide fiber of a specific composition.
Firstly, promote ordinary no molten drop effect for the carbonization membrane does not have molten drop, in dangerous occasions such as explosion, conflagration, both can not cause secondary damage because of the molten drop, have partial isolated effect to the thermal damage of environment moreover, be difficult for the fly ash promptly.
Secondly, not only the carbonized film is free from molten drops, but also after at least 50 times of water washing, the molten drop-free function of the carbonized film is still efficiently maintained and cannot be remarkably degraded.
The further preferred technical scheme is as follows: the polyesteramide fiber content was 56.6wt%, and the quantitative ratio of ester bonds to amide bonds in the polyesteramide fiber was 14.6: 1.
In the invention, the applicant finds that after the specific polyesteramide fiber with the content of 56.6wt% and the proportion of 14.6:1 is used for weaving to prepare the fabric, the fabric has the advantages of combining the two indexes of no-molten-drop carbonization film-forming performance and no-molten-drop carbonization film-forming performance reduction range after multiple times of water washing, namely, the fabric has the advantages of large film-forming proportion after combustion in the initial wearing period, the flying rate of fly ash is lower than 2%, and after 50 times of water washing, the flying rate of fly ash generated by combustion of the fabric is still lower than 3%, namely, the carbonization film-free function is long-term effective.
The further preferred technical scheme is as follows: when the polyesteramide fiber is 54.2 to 56.6wt% excluding 56.6wt%, the ratio of the number of ester bonds to the number of amide bonds in the polyesteramide fiber is (10.2 to 14.6): 1 excluding 14.6: 1; when the content of the polyesteramide fiber is 56.6-62.5wt%, the number ratio of ester bonds to amide bonds in the polyesteramide fiber is (14.6-15.5): 1.
In the present invention, the applicant has found that when the content of the polyesteramide fiber is 54.2 to 56.6wt% but not 56.6wt%, if the ratio of ester bond and amide bond in the polyesteramide fiber is increased, the non-dripping effect of the carbonized film after multiple water washes is significantly deteriorated, so that the maximum ratio of ester bond to amide bond of 14.6:1 is limited.
On the other hand, when the content of the polyesteramide fiber is 56.6-62.5wt%, the proportion of ester bonds and amide bonds is properly increased, so that the carbonization film forming proportion of the initial fabric can be obviously improved on the premise of slightly reducing the water washing resistance of the non-droplet-forming performance of the carbonization film, and particularly, the carbonization film forming proportion is the highest in the group of polyesteramide fiber with the content of 56.6wt% and the proportion of ester bonds and amide bonds of 14.6:1, so that the priority of improving the carbonization film forming proportion is higher than the priority of prolonging the effective period of the non-droplet-forming performance of the carbonization film forming.
The further preferred technical scheme is as follows: the polyesteramide fiber had a length of 38mm and a linear density of 1.33 to 1.56 dtex.
The further preferred technical scheme is as follows: the breaking elongation of the polyesteramide fiber is 43-49%, and the official moisture regain is 0.6-0.7%.
The further preferred technical scheme is as follows: the melting point of the polyesteramide fiber is 245-248 ℃, the melting crystallization temperature is 170-190 ℃, and the limiting oxygen index LOI is 21.6-22.5%.
In the invention, the cotton fiber has basic non-molten drop effect, and the polyesteramide fiber is required to have at least relatively basic and primary non-molten drop effect, so that the length and linear density of the polyesteramide fiber are limited as above, and the polyesteramide fiber is finally ensured to have the outstanding performance of the limiting oxygen index LOI of 21.6-22.5%, and finally, the 'rear leg' of the non-molten drop effect of the cotton fiber is not dragged, but the non-molten drop effect is further improved into the non-molten drop effect of a carbonized film, and the fabric is ensured not to have a large amount of fly ash after being combusted.
The further preferred technical scheme is as follows: the fabric is prepared by a warp-weft weaving mode, the polyesteramide fibers, the cotton fibers and the polyester fibers are prepared into weft yarns, and the polyesteramide fibers and the polyester fibers are prepared into warp yarns.
The further preferred technical scheme is as follows: the warp density of the fabric is 390-520 pieces/10 cm, and the weft density is 200-280 pieces/10 cm.
The further preferred technical scheme is as follows: the flying rate of the fly ash after the initial fabric is burnt is less than or equal to 2 percent, and the flying rate of the burning fly ash after the fabric is washed by water for 50 times is less than or equal to 3 percent.
The further preferred technical scheme is as follows: the limiting oxygen index of the fabric under the GB/T5455-1997 standard is 22-26%, and no molten drop exists during combustion.
In the invention, the flying area of the flying ash after the fabric is burnt accounts for less than 3% of the whole area, thereby ensuring that a large amount of flying burning ash can not be generated.
The present invention has the following advantages.
Firstly, the fabric is in a molten drop-free mode after being burnt, the carbonized film is not easy to drop flying ash, and can still cover the skin to isolate partial heat.
Secondly, the non-molten drop performance of the carbonized film before the fabric is washed by water is very outstanding, the non-molten drop performance of the carbonized film after the fabric is washed by 50 times of water is still relatively excellent, and the non-molten drop performance of the carbonized film can be effective for a long time.
Thirdly, the warp and weft weaving mode of the fabric is simple and convenient, and the fabric has high application value in the fields of fire fighting and high-temperature operation.
