Description

Technical Field

[0001] The invention relates to the field of textile production, in particular to the field of household flame-retardant textiles. Background Art

[0002] Existing household fabrics such as mattress lining fabrics and pleated cotton used in mattresses all need to have a certain rebound effect, but the existing fabrics have limited rebound effect and poor flame retardant effect. Summary of the invention

[0003] The object of the present invention is to provide a novel high-elastic flame-retardant fabric with good rebound and flame-retardant effects.

[0004] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:

[0005] A new type of highly elastic flame-retardant fabric, the flame-retardant fabric components are as follows according to weight percentage:

[0006] Viscose yarn: 40%-60%, PBT high elastic yarn: 30-53%, polyester staple fiber: 6-16%. After the above ingredients are laid into a grey cloth, it is soaked in a flame retardant and then dried to obtain a finished flame retardant cloth.

[0007] As an optimization of the above solution, the viscose thread is a flame retardant viscose thread.

[0008] As a further optimization of the above solution, the specification of the PBT high-elastic yarn is 2DX51MM, the specification of the polyester staple fiber is 2-4DX51-90mm, and the specification of the viscose yarn is 1.5D-4D.

[0009] Moreover, the grey cloth manufacturing process is a non-needle punching process, including: according to the above percentage ratio, viscose yarn, PBT high elastic yarn and polyester staple fiber are mixed evenly to make the fiber yarns evenly interwoven, and then straight combed to lay the net to make the connection between the fiber yarns more stable, and then stitched. The non-needle punching process also includes: polyester filament reinforcement thread stitching, stitching the polyester filament reinforcement thread onto the fiber mesh layer after laying the net by a stitching machine.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Compared with existing stretch fabrics, the cost is lower. Compared with existing flame-retardant mattress fabrics, the cost is reduced by about 9%.

[0012] 2. Better rebound effect. PBT high-elastic yarn and viscose yarn are fully and evenly combined, and non-needle punching technology is adopted, that is, the high-speed needle punching process of the needle punching machine is cancelled, so that the fibers of PBT high-elastic yarn and viscose yarn form a stable natural hooking structure, which ensures the shape and elasticity of PBT high-elastic yarn itself, so that the overall fabric can have a higher rebound effect. And it can be transported by hollowing and compressing, which will not affect the rebound effect and is more convenient for transportation.

[0013] 3. Better flame retardant effect. Because the fabric has a high fluffiness and the gaps between the fibers are relatively large, it can better absorb the flame retardant when soaked in the flame retardant, and the flame retardant is more fully attached to the fiber, the attachment thickness is also thicker, and the flame retardant effect is better. At the same time, after the viscose yarn and the PBT high elastic yarn are fully mixed, even if the viscose yarn is carbonized after burning, an irregular carbonized network is formed inside the fabric, which has a better effect of blocking the flame.

[0014] 4. By adding an appropriate amount of polyester staple fibers, the combability of each fiber during the molding process is increased, and the connection stability between the fibers of the molded fabric is better.

[0015] 5. It has a wider range of applications. In addition to being used as mattress fabric, it can also replace memory foam, latex foam, etc. DETAILED DESCRIPTION

[0016] In order to further understand the content, features and effects of the invention of this application, the following embodiments are given:

[0017] A new type of highly elastic flame-retardant fabric, the flame-retardant fabric components are as follows according to weight percentage:

[0018] Flame retardant viscose yarn: 50%, PBT high elastic yarn: 40%, polyester staple fiber: 10%, and then processed by the following process:

[0019] Firstly, a non-needle punching process is used to lay the mesh into grey cloth, which is then soaked in a flame retardant and then dried to obtain a finished flame retardant cloth.

[0020] 6. Among them, the non-needle punching process includes: according to the above percentage ratio, the viscose yarn and the PBT high elastic yarn are mixed evenly to make the fiber yarns evenly interwoven, and then the fiber yarns are laid through a straight combing web to make the hooking between the fiber yarns more stable, and then the polyester filament reinforcement line is stitched on the fiber mesh layer after the web laying through a stitching machine to form a grey cloth. The non-needle punching process cancels the high-speed needle punching process of the needle punching machine. During the web laying and forming process, the fiber yarns will not be straightened due to the needle punching, so that the fiber yarns, especially the PBT high elastic yarns, are kept in a natural state to form a fiber mesh, so that the entire fiber mesh retains the elasticity of the PBT high elastic yarn, so that the overall fabric can have a higher rebound effect. And during transportation, it can be transported by hollowing and compressing, which will not affect the rebound effect and is more convenient for transportation. This embodiment increases the combability of each fiber in the forming process by adding an appropriate amount of polyester staple fibers, and the hooking stability between the fibers of the formed fabric is better. If polyester staple fibers are not added, the fibers are very difficult to comb and are easy to break. The polyester staple fibers also play a role in bridging the fibers.

[0021] In the above-mentioned flame retardant soaking process, the flame retardant content in the soaking water is 0.05% and the soaking time is about 13-15 minutes. In the drying process, the fabric is dried in an oven at a drying temperature between 170 and 210 degrees Celsius. In the soaking process, because the fabric has a high fluffiness and the gaps between the fibers are relatively large, the flame retardant is better absorbed during the flame retardant soaking, and the flame retardant is more fully attached to the fibers and the attachment thickness is also thicker. After drying, the attached flame retardant layer is also more stable and the flame retardant effect is better.

[0022] Finished product 300g / m 2 The natural thickness of heavy fabric can reach 10mm, and it is highly fluffy. After the viscose yarn and PBT high elastic yarn are fully mixed inside the fabric, even if the viscose yarn is carbonized after burning, an irregular carbonized network is formed inside the fabric, which has a better effect of blocking the flame.

[0023] In this embodiment, the specification of the PBT high elastic yarn is 2DX51MM, and the specification of the viscose yarn is 1.5D-4D.

[0024] In order to more fully demonstrate the technical effect of the present invention, the applicant conducted a number of tests on the flame-retardant fabric samples of the present invention. The details are as follows:

[0025] 1. Oxygen index test:

[0026] Test items Sample 1 Sample 2 Sample 3 Sample 4 average value Oxygen Index 32 30 31 32 31.5

[0027] Through testing, it can be seen that compared with the oxygen index of similar products (about 26), the technical sample of this application has a higher oxygen index, is less likely to burn, and has a better flame retardant effect.

[0028] 2. Combustion test results (sample sampling specifications are: 20cm*20cm, using a spray gun for combustion, flame length between 10cm-15cm, flame spray time 20 seconds):

[0029]

[0030] From the above test experiments, it can be seen that the surface flame of the sample of the present application extinguishes itself immediately after the flame is sprayed, and a carbonized layer is formed, and the carbonized layer has no perforations and is relatively complete. It can be seen that the flame retardant effect of the sample of the present application meets the requirements and has a high flame retardant effect.

[0031] 3. Rebound rate test (the sample is placed in a hollow bag and compressed for 48 hours, and then the sample is taken out to allow it to rebound naturally, and the thickness of the sample before and after is compared).

[0032]

[0033] It can be seen from the above test experiments that the technical sample of the present application still has a very good rebound effect even after being hollow compressed for 48 hours.

[0034] The above is a technical embodiment of the present invention. In addition, for viscose yarn and PBT high elastic yarn, the specific content can be: viscose yarn can take any value between 40%-60%, such as 40% or 60%, etc., PBT high elastic can take any value between 30-53%, such as 30% or 50%, etc., polyester staple fiber can take any value between 6-16%, such as 6% or 16%, etc., and the above options all have the same technical effects.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express the preferred implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
