Description

Technical Field

[0001] The invention relates to a leather-based perforated fabric for automobile seats, in particular to a high-strength, low-odor leather-based perforated fabric for automobile seats and a preparation method thereof. Background Art

[0002] In recent years, my country's macroeconomic growth has continued, and the living standards of residents have improved rapidly. With the substantial increase in consumption levels, the automotive sector has also seen rapid growth, especially in the new energy market, where demand is growing. With the booming automotive market, the market for automotive interior fabrics has also gradually expanded. The textile fibers used for automotive interiors are mostly synthetic fibers, and polyester fibers are widely used because of their good wear resistance, tear resistance, and mildew resistance. Due to their high strength, elongation, and fire resistance, water resistance, and UV resistance, their use in various applications continues to increase.

[0003] However, leather-based fabrics made of polyester will be sizing and oiling during the spinning and weaving of the polyester material itself, and may become dirty and moldy during transportation and storage. At the same time, various auxiliaries will be added during the subsequent dyeing process. This leads to the woven leather-based fabrics often having a more obvious residual odor. The level of this odor is much higher than the 3.5 level specified for automotive interior fabrics, which requires the fabric to be deodorized.

[0004] The existing deodorization treatment method is mainly based on water washing, that is, after multiple rounds of water washing on the leather-based fabric made of polyester fiber, the residual odor on the leather-based fabric is registered and reduced. It should be noted that in principle, through repeated rounds of water washing, the odor on the leather-based fabric can reach the odor level specified for automobile interior, such as below level 3.5. However, after 1 to 2 ordinary water washings, the efficiency of water washing deodorization will be greatly reduced. If the residual odor on the fabric is to be reduced in the future, multiple water washings are required. After comprehensively weighing the economic factors and the deodorization efficiency, it can be concluded that if the purpose of reducing the residual odor level on the surface of the fabric is achieved only by increasing the number of water washings, the economic benefits are obviously low or even negative. For this reason, it is very necessary to develop a high-strength, low-odor automobile seat leather-based perforated fabric and a preparation method thereof that can balance economic factors and deodorization effects.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Example 1

[0050] like Figure 3 , Figure 4 As shown, the present invention discloses a high-strength, low-odor automobile seat leather-based perforated fabric, which specifically adopts 75D / 36F polyester low-elastic yarn (AAA) and 75D / 36F polyester filament (AA), with a specification of 2400 head threads, and is woven with a Karl Mayer warp knitting machine with three combs. It should be noted that in order to make the above-mentioned fabric dyed evenly, the weaving quality more stable, and the physical properties of the woven fabric more outstanding, this scheme recommends that the yarn used be AAA grade or AA grade yarn with similar performance.

[0051] In order to make the automobile seat leather-based perforated fabric made of the woven fabric have the advantages of high strength and low odor, the present invention also discloses a preparation method of a high-strength and low-odor automobile seat leather-based perforated fabric: specifically,

[0052] Step S1, material selection: 75D / 36F polyester low-elastic yarn and 75D / 36F polyester filament yarn are selected as raw material yarns.

[0053] Step S2, warping: warping the 75D / 36F polyester low-elastic yarn and the 75D / 36F polyester filament on a warping machine according to the requirements of width and cross density and the requirement of 2400 head grains.

[0054] Step S3, weaving: using a Karl Mayer warp knitting machine, weaving is performed using three guide bars.

[0055] Step S4, finishing before dyeing: the woven fabric is subjected to pre-treatment such as S41 defect inspection → S42 edge rolling.

[0056] Step S5, dyeing treatment: including S51 pre-treatment degreasing → S52 dyeing in sequence;

[0057] Step S6: Washing and removing odor: Washing the fabric with water to remove residual additives, residues and other odor-carrying substances in the fabric;

[0058] Step S7: dehydration and opening: dehydration of the fabric and opening of the fabric to prepare for subsequent drying and shaping;

[0059] Step S8: drying: drying the still damp fabric to make the fabric size basically stable;

[0060] Step S9: Finished product shaping: The fabric is shaped to fix the style, width, weight, thickness, etc. of the finished product.

[0061] It should be noted that the purpose of the edge rolling step before dyeing is to roll the edge of the cloth flat to avoid curling during degreasing and dyeing. In this solution, the temperature is controlled at 90°C, the cloth feeding speed is 15m / min, and the roller pressure is 0.4mpa.

[0062] The purpose of the pre-treatment degreasing in step S51 is to use a high-temperature and high-pressure overflow dyeing machine, and degreasing and washing in the cylinder, which can remove the oil, slurry, and dirt on the cloth surface to a great extent, ensure the cleanness of the cloth surface, and facilitate the uniformity of dyeing. It should be noted that in this solution, the degreasing temperature is controlled at 90°C and the time is 20 minutes. The auxiliary agents used can be: degreasing spirit, dispersing leveling agent, and liquid alkali.

[0063] After the current degreasing process is completed, the dyeing process phase is entered into step S52. In this phase, the dyeing temperature is set to 130°C, the time is 30 minutes, the bath ratio is 1:10, and the nozzle is 100#.

[0064] In addition, it should be noted that if the color of the fabric is dark, it can be considered to complete step S51 and step S52 in one step, that is, dyeing in the same bath, degreasing and dyeing in one step, so as to shorten the overall time of dyeing process.

[0065] When dyeing is completed, it enters the S6 water washing and deodorization stage, which is specifically divided into the following three steps, namely step S61 overflow water washing. At this time, the temperature of the washing water is controlled at 70°C and the time is controlled at 20 minutes. During this period, the washing water in the above temperature range is continuously fed into the dyeing vat of the dyeing machine to continuously circulate and update the washing water for washing out the residues in the fabric, so as to avoid the accumulation and increase of concentration of the precipitates in the fabric in the dyeing machine, which makes it difficult for the subsequent residues to precipitate. It should be noted that before overflow cleaning, the residual dye liquid in the dyeing machine needs to be drained first to improve the overflow cleaning efficiency. When the overflow cleaning is completed, the part of the washing water remaining in the dyeing machine also needs to be drained.

[0066] After the overflow cleaning in step S61 is completed, step S62, the first ordinary water washing, is performed. Specifically, the washing water is refilled into the dyeing machine, the temperature of the washing water is maintained at 60°C, the time is 30 minutes, and then the washing water is drained again. The purpose of this step is to wash out the remaining residues by immersion.

[0067] After the first common water washing is completed, the washing water is again injected into the dyeing machine to perform S63, the second common water washing. It should be noted that during the second common water washing, the temperature of the washing water needs to be maintained at 50° C. for 20 minutes, and then the washing water is drained.

[0068] After one overflow wash and two washes, the auxiliaries remaining in the fabric during weaving and the auxiliaries during dyeing can be basically washed away.

[0069] Next, the S7 dehydration and width opening process step is carried out to remove the residual moisture in the fabric through centrifugal dehydration, and open the fabric from the rope shape to facilitate the subsequent drying and shaping.

[0070] Next is S8 drying. It should be noted that the dyed cloth is still damp after dehydration and opening, and the residual moisture is stabilized by shaping and drying, which is convenient for the subsequent application of auxiliaries. It should be noted that in this scheme, the drying temperature is controlled at 140℃, the speed is 30m / min, and positive overfeed is about +5% to control the tension.

[0071] Finally, step S9 and the finished product shaping process are carried out. It should be noted that the shaping of the finished product is the last step of fabric processing. There are three purposes. First, to fix the basic requirements of the finished product such as style, width, weight, thickness, etc.; second, to add functional additives to give the fabric high strength, dimensional stability, and wrinkle resistance; third, to remove the residual odor on the fabric to a great extent. Attention should be paid during shaping production: the empty machine should be started for 20 minutes before shaping, the air volume should be turned to the maximum, and the oven door should be opened to help the gas carrying odorous substances to dissipate. In this scheme, the shaping temperature is controlled at 160°C, the cloth feeding speed is controlled at 25m / min, and the positive overfeed is about 5% to control the tension. It should be noted that during the shaping process, functional additives, such as flame retardants, can be added to the fabric to make the fabric have good flame retardant function (can reach A-0 grade). In addition, it should be noted that the dosage of functional additives is usually 20g / L.

[0072] After being treated by the above method, the obtained fabric has the following physical properties: Figure 6 As shown, the final odor level of the fabric can reach ≤3.5.

[0073] Example 2

[0074] like Figure 3 , Figure 4 As shown, the present invention discloses a high-strength, low-odor automobile seat leather-based perforated fabric, which specifically adopts 75D / 72F polyester low-elastic yarn (AAA) and 75D / 36F polyester filament (AAA), with a specification of 2440 threads, and is woven by a Karl Mayer warp knitting machine with three combs. It should be noted that in order to make the above-mentioned fabric dyed evenly, the weaving quality more stable, and the physical properties of the woven fabric more outstanding, this solution recommends that the yarn used be of AAA quality.

[0075] In order to make the automobile seat leather-based perforated fabric made of the woven fabric have the advantages of high strength and low odor, the present invention also discloses a preparation method of a high-strength and low-odor automobile seat leather-based perforated fabric: specifically,

[0076] Step S1, material selection: 75D / 72F polyester low-elastic yarn and 75D / 36F polyester filament are selected as raw material yarns.

[0077] Step S2, warping: warping the 75D / 72F polyester low-elastic yarn and the 75D / 36F polyester filament on a warping machine according to the requirements of width and cross density and the requirement of 2440 head warps.

[0078] Step S3, weaving: using a Karl Mayer warp knitting machine, weaving is performed using three guide bars.

[0079] Step S4, finishing before dyeing: the woven fabric is subjected to pre-treatment such as defect inspection and edge rolling.

[0080] Step S5, dyeing treatment: including S51 pre-treatment degreasing → S52 dyeing in sequence;

[0081] Step S6: Washing and removing odor: Washing the fabric with water to remove residual additives, residues and other odor-carrying substances in the fabric;

[0082] Step S7: dehydration and opening: dehydration of the fabric and opening of the fabric to prepare for subsequent drying and shaping;

[0083] Step S8: drying: drying the still damp fabric to make the fabric size basically stable;

[0084] Step S9: Finished product shaping: The fabric is shaped to fix the style, width, weight, thickness, etc. of the finished product.

[0085] It should be noted that the purpose of edge rolling in the finishing process before dyeing is to make the edge of the cloth smooth and avoid curling during degreasing and dyeing. In this solution, the temperature is controlled at 100°C, the cloth feeding speed is 25m / min, and the roller pressure is 0.3mpa.

[0086] The purpose of the pre-treatment degreasing in step S51 is to use a high-temperature and high-pressure overflow dyeing machine, and degreasing and washing in the tank, which can remove the oil, slurry, and dirt on the cloth surface to a great extent, ensure the cleanness of the cloth surface, and facilitate the uniformity of dyeing. It should be noted that in this solution, the degreasing temperature is controlled at 85°C and the time is 30 minutes. The auxiliary agents used can be: degreasing spirit, dispersing leveling agent, and liquid alkali.

[0087] After the current degreasing process is completed, the dyeing process phase is entered into step S52. In this phase, the dyeing temperature is set to 130°C, the time is 30 minutes, the bath ratio is 1:10, and the nozzle is 110#.

[0088] In addition, it should be noted that if the color of the fabric is light, then step S51 and step S52 should be completed in two steps to fully remove the impurities on the fabric surface. 、 Oil, dirt, improve the permeability of fabric surface and avoid staining.

[0089] When dyeing is completed, it enters the S6 water washing and deodorization stage, which is specifically divided into the following three steps, namely step S61 overflow water washing. At this time, the temperature of the washing water is controlled at 60°C and the time is controlled at 30 minutes. During this period, the washing water in the above temperature range is continuously fed into the dyeing vat of the dyeing machine to continuously circulate and update the washing water for washing out the residues in the fabric, so as to avoid the accumulation and increase of concentration of the precipitates in the fabric in the dyeing machine, which makes it difficult for the subsequent residues to precipitate. It should be noted that before overflow cleaning, the residual dye liquid in the dyeing machine needs to be drained first to improve the overflow cleaning efficiency. When the overflow cleaning is completed, the part of the washing water remaining in the dyeing machine also needs to be drained.

[0090] After the overflow cleaning of step S61 is completed, step S62, the first normal water wash, is carried out. Specifically, the cleaning water is re-injected into the dyeing machine, and the temperature of the cleaning water is maintained at 60°C for 30 minutes, and then the cleaning water is drained again. The purpose of this step is to wash out the remaining residues by immersion. It should be noted that in order to improve the deodorization effect, clay Transtex PRE 1200A is also added to the cleaning water of the first normal water wash, and the weight proportion of clay Transtex PRE1200A in the cleaning liquid formed by mixing with the cleaning water is 2%. After the first normal water wash is completed, cleaning water is injected into the dyeing machine again to carry out S63, the second normal water wash. It should be noted that during the second normal water wash, the temperature of the cleaning water needs to be maintained at 50°C for 30 minutes, and then the cleaning water is drained.

[0091] After one overflow wash and two washes, the auxiliaries remaining in the fabric during weaving and the auxiliaries during dyeing can be basically washed away.

[0092] Next, the S7 dehydration and width opening process step is carried out to remove the residual moisture in the fabric through centrifugal dehydration, and open the fabric from the rope shape to facilitate the subsequent drying and shaping.

[0093] Next is S8 drying. It should be noted that the dyed cloth is still damp after dehydration and opening, and residual moisture is left. Through shaping and drying, the cloth is basically dry and dimensionally stable, which is convenient for the subsequent application of additives. It should be noted that in this scheme, the drying temperature is controlled at 150°C, the speed is 25m / min, and positive overfeed is about +3% to control the tension.

[0094] Finally, step S9 and the finished product shaping process are carried out. All you need to know is that the shaping of the finished product is the last step in fabric processing. There are three purposes. First, to fix the basic requirements of the finished product such as style, width, weight, thickness, etc.; second, to add functional additives to give the fabric high strength, dimensional stability, and wrinkle resistance; third, to remove the residual odor on the fabric to a great extent. Things to note during shaping production: run the empty machine for 20 minutes before shaping, turn the air volume to the maximum, and open the oven door to help the gas carrying odorous substances to dissipate. In this solution, the shaping temperature is controlled at 170°C, the cloth feeding speed is controlled at 30m / min, and positive overfeeding of about 10% is used to control the tension. It should be noted that during the shaping process, functional additives can be added to the fabric, such as a functional tear enhancer 10g / L, so that the fabric has good tear resistance. For detailed performance, see Figure 6 . .

[0095] After being treated by the above method, the obtained fabric has the following physical properties: Figure 6 As shown, the final odor level of the fabric can reach ≤3.0.

[0096] Comparative Example

[0097] The difference between this scheme and Example 1 and Example 2 is that the yarn grade is AA polyester filament, the number of head grains is 2320, no edge rolling, dyeing and degreasing in the same bath, dyeing are completed in one step, conventional water washing is performed once after dyeing, no additional auxiliaries are added for shaping, and the oven is not turned on. The physical properties of the fabric prepared by this scheme are shown in Figure 6 .

[0098] It should be noted that if Figure 7 As shown in the figure, the clay Transtex PRE 1200A in this solution is mainly used in the pre-treatment of cotton knitted fabrics and cotton cheese yarns in the industry, and can also be used to remove silicone oil spots and waterproof spots, that is, it is mainly used as a bleaching and decontamination auxiliary. In this solution, the original bleaching and decontamination auxiliary clay TranstexPRE 1200A is used for deodorization treatment, which has achieved unexpected technical results.

[0099] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
