Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to an edge-resistant anti-splitting fabric and its manufacturing process. Background Technology

[0002] In existing technologies, conventional fabrics are woven by selecting yarns of different materials. After weaving, the edge structure is not high, and the fabric is prone to loose threads and cracking.

[0003] To prevent edge cracking, water-based acrylic emulsions or water-based polyurethane dispersions are usually used as adhesives to bond the warp and weft of the fabric together to prevent edge cracking; however, they are not ideal for recycling and the process is relatively complex.

[0004] Therefore, a production process is needed to prevent edge cracking of the fabric without the use of acrylic emulsions or water-based polyurethane dispersions. Summary of the Invention

[0005] To address the problem of fabric edges easily cracking, this application provides an edge-resistant anti-cracking fabric and its manufacturing process.

[0006] In a first aspect, this application provides an edge-resistant anti-cracking fabric, employing the following technical solution:

[0007] An edge-resistant anti-splitting fabric includes yarn comprising warp yarns, weft yarns, and hot-melt yarns, the hot-melt yarns being located at the edge of the fabric; the hot-melt yarns are made from the following raw materials in parts by weight: 40-50 parts of polyethylene terephthalate, 30-40 parts of butylene terephthalate, 5-10 parts of low-molecular-weight flame retardant, 1-5 parts of copolymer, 0.5-1 part of tributyl phosphate, 0.5-1 part of magnesium hydroxide, and 1-2 parts of zinc acetate.

[0008] By adopting the above technical solution, the hot melt yarn has a low melting point and good adhesion after melting. When heated to a certain temperature, it will soften and melt into a viscous fluid with a certain fluidity. After cooling, it will solidify again into a solid. Therefore, the edge of the fabric formed by weaving it with other yarns as an edge yarn is firm and not easy to crack.

[0009] This application also incorporates a low-molecular-weight flame retardant into polyester raw materials, freezing the polymer chains into an amorphous state. When the temperature is slowly increased above the glass transition temperature, the ends begin to move, and the molecular chains near the crystallization temperature enter the crystal lattice. At this point, the presence of low-molecular-weight substances increases lattice defects and incomplete crystallization, thereby lowering the melting point of the polyester. Simultaneously, the copolymer alters the melting point of the polyester by influencing its melting point, achieving the goal of lowering the polyester melting point. Under the synergistic effect of the low-molecular-weight flame retardant and low-molecular-weight plasticizer, the hot melt wire not only has high strength but also lowers the melting point, saving energy. This hot melt wire has good spinning properties, allowing for melt spinning and composite spinning with conventional yarns.

[0010] In one specific embodiment, the copolymer is a mixture of a first component and a second component in a mass ratio of 1:(1-4); the first component is one or more of adipic acid, sebacic acid and their esters; and the second component is one or more of propylene glycol, butanediol and polyethylene glycol.

[0011] By adopting the above technical solution, the first component itself contains flexible segments, thereby relatively reducing the content of benzene rings in the polyester, giving the polyester molecules more conformations in the molten state and increasing the molten entropy; the second component can disrupt the tightly aggregated state of the polyester, that is, disrupt the regularity of the polyester molecular chains, increase the distance between the polyester molecular chains, thereby weakening the interaction forces between the polyester molecular chains and reducing the heat of molten melt; the first and second components work together to reduce the melting point of the polyester by reducing the heat of molten melt and increasing the molten entropy of the polyester.

[0012] In one specific implementation, the method for preparing the low-molecular-weight flame retardant includes the following steps:

[0013] P1, 10-15 parts by weight of styrene, 0.02-0.1 parts by weight of an azo compound or organic peroxide as an initiator, 2-10 parts by weight of a dithioester derivative as a chain transfer agent and a solvent are mixed and reacted at 50-150℃ for 2-10 hours under inert gas protection to obtain styrene homopolymer;

[0014] P2, the styrene homopolymer is added with 25-30 parts by weight of 1,4-butadiene under inert gas protection and reacted at 50-150℃ for 2-10 h to obtain a styrene-butadiene diblock copolymer;

[0015] P3, the styrene-butadiene diblock copolymer is reacted with 6-10 parts by weight of styrene under inert gas protection at 50-150℃ for 2-10 hours to obtain a styrene-butadiene-styrene triblock copolymer.

[0016] P4, Isobutanol is added to the styrene-butadiene-styrene triblock copolymer and the temperature is raised to 30-70℃ to dissolve the copolymer. Under the heat preservation condition, brominating agent is added and stirred for 1-15 hours. After the reaction is completed, methanol is precipitated and filtered. The mixture is then vacuum dried to constant weight to obtain a low molecular weight flame retardant. The mass ratio of the styrene-butadiene-styrene triblock copolymer, isobutanol, and brominating agent is 1:(5-10):(1-5).

[0017] By adopting the above technical solutions, the low molecular weight flame retardant of the present invention uses the RAFT polymerization method, which can control the degree of polymerization to form a low molecular weight product, thereby enhancing compatibility with other components; at the same time, the bromination method used in the low molecular weight flame retardant of the present invention enables the triblock structure to be chemically bonded with a high content of bromine, thereby improving the flame retardant effect.

[0018] In one specific implementation, the process between P3 and P4 further includes: pouring the styrene-butadiene-styrene triblock copolymer into a solvent under stirring until completely dissolved, and then precipitating it in methanol; after repeating the dissolution and precipitation process 3-5 times, drying it in a vacuum oven at 30-100℃ to constant weight to obtain a low molecular weight styrene-butadiene-styrene triblock copolymer.

[0019] By employing the above technical solution, impurities in the copolymer are removed through repeated dissolution and precipitation, thereby improving the purity of the copolymer.

[0020] In one specific implementation, the brominating agent is bromine chloride or tetraethylammonium bromide; the azo compound is azobisisobutyronitrile, azobisisoheptanenitrile, or azobisisobutyramidine hydrochloride; the organic peroxide is benzoyl peroxide or benzoyl tert-butyl peroxide; and the dithioester derivative is 4-cyano-4-(thiobenzoyl)valerate, S-(thiobenzoic acid) mercaptoacetic acid, or phenyldithioacetic acid-1-phenylacetic acid.

[0021] By employing the above technical solution, this application uses styrene and 1,4-butadiene as polymerizing monomers, azo compounds or organic peroxides as initiators, and disulfide derivatives as chain transfer agents. A reversible addition-fragmentation chain transfer (RAFT) polymerization method is used to prepare a styrene-butadiene-styrene triblock copolymer with controllable molecular weight through solution polymerization. This polymer, after bromination with a brominating agent, yields a highly efficient flame retardant with high bromine content and good stability, exhibiting excellent compatibility with other substances. Furthermore, by controlling the mass of the monomers and brominating agent, a low-molecular-weight flame retardant with high bromine content can be obtained.

[0022] In one specific implementation, the method for preparing the hot melt wire includes the following steps:

[0023] Mixing and extruding appropriate weight parts of hot melt wire raw materials to obtain blended wires;

[0024] The blended yarn is stretched in a saturated steam bath and cooled to room temperature before being heat-set.

[0025] By adopting the above technical solution, under the high temperature during blending, the low molecular weight flame retardant is uniformly mixed with the melts of polyethylene terephthalate and butylene terephthalate and then stretched by steam. When the temperature is slowly raised above the glass transition temperature, the chain segments begin to move. Near the crystallization temperature, the molecular chains will enter the crystal lattice. At this time, due to the presence of low molecular weight substances, the crystal lattice defects increase and the crystal lattice imperfections increase, thereby lowering the melting point, improving the bonding strength of the hot melt wire, reducing its melting point, and saving energy consumption when used to prevent cracking at the edge of fabrics.

[0026] In one specific implementation, the temperature during mixing of the hot melt wire raw materials is 300-320°C.

[0027] By adopting the above technical solution, the mixing temperature is optimized, thereby improving the uniformity and stability of the mixture.

[0028] Secondly, this application provides a manufacturing process for edge-resistant anti-cracking fabric, employing the following technical solution:

[0029] A manufacturing process for edge-resistant anti-splitting fabric includes the following steps:

[0030] S1, one or more hot melt wires are set at the edge of the fabric and participate in the interweaving of warp and weft yarns to obtain the primary fabric;

[0031] S2, dyeing the primary fabric to obtain the intermediate fabric; the temperature during the dyeing process is not higher than the melting point of the hot melt wire;

[0032] S3, heat-press the middle fabric to melt the hot melt wire, then let it cool naturally.

[0033] By adopting the above technical solution, and by using molten wire to weave with warp and weft yarns, a melting point is formed to lock the edge of the fabric, making the edge of the formed fabric firm and not easy to crack.

[0034] In one specific implementation scheme, the warp and weft yarns are both 50-120 tex; the warp density is 10-200 yarns / cm, the weft density is 8-40 yarns / cm, the warp tightness is greater than 60%, and the weft tightness is greater than 30%.

[0035] By adopting the above technical solution, the warp yarn is required to have high strength, good elasticity, high strength, few hairs, and be dense and strong; the weft yarn is required to have lower strength than the warp yarn and be soft.

[0036] In one specific implementation scheme, in step S3, the temperature during the hot-stamping process is 100-140℃, and the hot-stamping time is 5-300s.

[0037] By adopting the above technical solution, the heat treatment temperature is higher than the temperature of the hot melt wire, which facilitates bonding with the warp and weft yarns after melting, without affecting the color and appearance of the fabric. The fabric edge adhesion is high and will not crack.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. This application achieves a strong fabric edge by setting hot melt wires at the edge of the fabric and weaving them with warp and weft yarns, making the fabric edge firm and less prone to cracking;

[0040] 2. This application reduces the melting point of the hot melt wire by adding low-molecular-weight flame retardants and copolymers, thereby saving energy for subsequent hot heat treatment;

[0041] 3. In this application, the copolymer is a mixture of the first component and the second component, which work synergistically to increase the melt entropy and reduce the melt heat, respectively, thereby further reducing the melting point of the polyester. Detailed Implementation

[0056] Preparation Example 3-13

[0057] As shown in Table 1, the main difference between preparation examples 3-13 lies in the different proportions of raw materials.

[0080] Comparative Example 1

[0081] The difference between this comparative example and Example 1 is that the low molecular weight flame retardant and copolymer in Preparation Example 3 are replaced with 5 kg of ethylene terephthalate and 5 kg of butylene terephthalate in equal amounts.

[0082] Comparative Example 2

[0083] The main difference between this comparative example and Example 1 is that the low molecular weight flame retardant in Preparation Example 3 is replaced by an equal amount of copolymer (1 kg adipic acid and 4 kg propylene glycol).

[0084] Comparative Example 3

[0085] The main difference between this comparative example and Example 1 is that the copolymer in Preparation Example 3 is replaced in equal amounts with a low molecular weight flame retardant.

[0086] Comparative Example 4

[0087] The main difference between this comparative example and Example 1 is that adipic acid is replaced with propylene glycol in equal amounts.

[0088] Comparative Example 5

[0089] The main difference between this comparative example and Example 1 is that propylene glycol is replaced with an equal amount of adipic acid.

[0090] Comparative Example 6

[0091] The main difference between this comparative example and the embodiment is that the hot melt yarns around the fabric are replaced with warp and weft yarns in equal amounts.

[0092] Visual inspection reveals that the fabrics prepared in Examples 1-10 of this application have firm edges and are not prone to cracking, while the fabrics prepared in Comparative Example 6 have poor edge firmness, low structural strength, are prone to loose threads and cracking, and have lint.

[0093] The melting point of the hot melt wires obtained in Preparation Examples 3-11 and Comparative Examples 1-5 was tested. The specific process was as follows: the prepared samples were dried in a vacuum oven at 110℃ for 12h. 10mg of the sample was placed in an aluminum crucible of DSC. N2 was used as the protective gas, and the scanning test was performed according to the following procedure: (1) 25℃, constant temperature for 1min; (2) 25-275℃, heating rate 10℃ / min; (3) 275℃, constant temperature for 2min; (4) 275-25℃, cooling rate 10℃ / min; (5) 25℃, constant temperature for 1min; (6) 25-275℃, heating rate 10℃ / min. The specific test results are shown in Table 3.

[0094] Table 3. Test data of melting point properties of hot melt wires in Preparation Examples 3-11 and Comparative Examples 1-5

[0095]

[0096] Referring to Table 3, from Preparation Examples 3-11 and Comparative Example 1, it can be seen that by adding low molecular weight flame retardants and copolymers to the hot melt adhesive system, the melting point of the hot melt wire is effectively reduced. When the low melting point hot melt wire is applied to the production process of edge-resistant fabric, the temperature during dyeing and heat treatment can be effectively reduced, thereby reducing energy consumption.

[0097] Referring to Table 3, and from Preparation Example 3 and Comparative Examples 2-3, it can be seen that the simultaneous addition of low-molecular-weight flame retardants and copolymers to the hot melt adhesive system in this application has a better effect on reducing the melting point of hot melt wires than adding low-molecular-weight flame retardants and copolymers alone. The low-molecular-weight flame retardant freezes the polymer chain segments, making them amorphous. When the temperature is slowly increased to above the glass transition temperature, the ends begin to move, and the molecular chains near the crystallization temperature enter the crystal lattice. At this time, due to the presence of low-molecular-weight substances, the lattice defects increase, the incomplete crystallization increases, and thus the melting point of polyester is reduced. At the same time, the copolymer reduces the melting point of polyester by affecting the molecular structure of polyester. The low-molecular-weight flame retardant and copolymer reduce the melting point of polyester from two different angles and have a synergistic effect.

[0098] Referring to Table 3, and from Preparation Example 3 and Comparative Examples 4-5, it can be seen that the hot melt wire prepared by simultaneously adding adipic acid and propylene glycol as copolymers in the hot melt adhesive system has a lower melting point than the hot melt wire prepared by adding adipic acid and propylene glycol alone. Adipic acid itself contains flexible segments, thereby relatively reducing the content of benzene rings in the polyester, giving the polyester molecules more conformations in the molten state and increasing the melt entropy. Propylene glycol can disrupt the compact aggregate state of the polyester, that is, disrupt the regularity of the polyester molecular chains, increase the distance between the polyester molecular chains, thereby weakening the interaction forces between the polyester molecular chains and reducing the heat of melting. Under the combined effect of adipic acid and propylene glycol, the melting point of the polyester is lowered by reducing the heat of melting and increasing the melt entropy of the polyester, which has a good synergistic effect.

[0099] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
