Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a method for making soft fabrics. Background Art

[0002] As people's living standards improve, the performance requirements for clothing fabrics are getting higher and higher, and the performance of clothing fabrics includes specification stability, environmental protection, softness, etc. At present, in order to obtain a soft feel, fabrics on the market usually use methods such as adding softeners, brushing, high-pressure airflow softening finishing, and using hairy yarns, but fabrics made using the above methods have some disadvantages.

[0003] Regarding the softening method with softeners, the softeners currently used are mainly silicone soft oils, but silicone soft oils have a certain impact on the color fastness and color presentation of clothing, and the setting of process parameters should be noted during the processing, otherwise silicone soft oils may have defects such as demulsification, and improper handling will also damage the feel of the fabric. Regarding the method of ordinary brushing, although relatively soft fabrics can be obtained, the self-rotation speed of the small hair roller of the existing brushing machine is only 1200r / min, and the napping effect achieved after brushing is not enough. Regarding the method of using a high-pressure airflow softening finishing machine, it is to make the fabric in a rope-like structure undergo continuous high-pressure gas violent blowing inside the machine, which not only wastes energy, but also makes the specifications of the fabric difficult to control, and there are also disadvantages such as expensive machines and high fabric costs. Regarding the method of using feather yarn, the cost is high, and the fabric woven from the feather yarn has poor fluff and feel.

[0004] Therefore, it is urgent to design a method for making soft fabrics to solve the above-mentioned technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a method for making soft fabrics, which can improve the softness and environmental friendliness of the fabrics, meet the requirements of ultra-fine and ultra-soft fabrics, and eliminate the addition of silicone soft oil, which is more environmentally friendly and improves user experience.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The present embodiment provides a method for making a soft fabric. The method is simple and can improve the softness of the fabric 100. It also eliminates the use of chemical additives such as silicone oil, thereby improving the environmental performance of the fabric 100 made by the method, and further improving the user experience of the fabric 100 made by the method.

[0039] In this embodiment, please refer to Figure 1 The method for making the soft fabric comprises:

[0040] S1: Pre-treatment: Provide yarn and shape the yarn into grey cloth. That is, select the required yarn, make it through the prescribed weaving method and shape it into grey cloth, and then the production of grey cloth can be completed. The production of grey cloth has a great influence on the finished fabric 100, so it is particularly important to choose the right yarn and weaving method.

[0041] Specifically, step S1 includes:

[0042] S11: Weaving the fabric: providing yarns to obtain the fabric through high-density weaving.

[0043] Furthermore, the yarn in this embodiment is made of ultrafine fiber, which has high elasticity and can meet the requirements of ultrafine and dense fabric 100.

[0044] Optionally, the yarn selected in this embodiment is polyester filament 15D / 48F (fiber thickness is 15 denier, composed of 48 monofilaments), which is blended with 20D polyester, and the composition ratio of the two is: 68% polyester and 32% polyester.

[0045] Furthermore, the high-density weaving method in this embodiment uses a double-sided jacquard weaving method, and the woven fabric 100 is relatively dense. Optionally, the machine used in the above high-density weaving method is a double-sided 38-inch ordinary circular machine with a total needle number of 5340. The high-density fabric 100 can be woven by this loom.

[0046] Optionally, the grey cloth woven using the specified weaving structure diagram in this embodiment is a double-sided jacquard structure, the length of the two single-sided yarns is 12cm / 100G, the length of the middle needle-holding part yarn is 13cm / 100G, and the length of the tension yarn is 6.5cm / 100G. This weaving method can make the grey cloth fabric tighter.

[0047] It is understandable that the selection of yarn and the weaving method in this embodiment can be changed according to actual needs and are not specifically limited here.

[0048] S12: Degreasing, drying and setting of the grey cloth: The grey cloth is degreased, dried and set by a setting machine to obtain the set grey cloth. High temperature setting is to heat-dry the grey cloth to ensure the stability of the specifications of the grey cloth, reduce wrinkles and improve the flatness of the fabric 100.

[0049] Specifically, the setting machine of this embodiment is a setting machine with a degreasing tank in front, which can directly degrease, dry and set the grey cloth, greatly reducing water consumption (degreasing by degreasing machines consumes more water) and energy consumption, reducing turnover processes, and improving the production efficiency of fabric 100; while saving manpower and material resources. Optionally, the degreasing agent added to the degreasing tank is LYS, the optimal concentration of which is 2.2g / l, and 70° hot water is used. After degreasing, the temperature for drying in the setting machine oven is 200°, and the drying time is 30 seconds.

[0050] S2: Dyeing: dyeing and drying the grey cloth to obtain the dyed fabric 100; currently, due to the diversity of colors of clothes, the fabric 100 needs to be dyed during the production process.

[0051] Specifically, step S2 includes:

[0052] S21: Dyeing: dyeing the grey cloth by adding dye into a dyeing vat to obtain a dyed grey cloth; that is, dyeing the grey cloth by placing it in an air flow vat or a water flow vat. After dyeing, the fabric 100 needs to be fully rinsed to remove floating colors, impurities, etc.

[0053] Optionally, during the dyeing process, green and environmentally friendly dyes are selected to ensure the environmental performance of the clothes, that is, the safety to the user's body.

[0054] S22: Dehydrate, loosen and dry the dyed fabric to obtain the dyed fabric 100. The drying process can be performed by a high-temperature drying machine, and the initial fabric 100 can be obtained after the fabric 100 is dried and shaped.

[0055] Please refer to Figure 1 and Figure 2 S3: Brushing: The dyed fabric 100 is brushed by a high-speed brushing machine to make the outer surface of the fabric 100 soft. The high-speed brushing machine is provided with at least seven brush structures 210, and the maximum rotation speed of the brush structure 210 is not less than 2000r / min. The fabric 100 enters the high-speed brushing machine in a flat state, and the guide roller and other devices inside the machine support the entire fabric 100 steadily, and then enters the area where the brush structure 210 is located. Through the external force such as continuous beating and friction of the brush structure 210 on the fabric 100, the surface of the fabric 100 has a soft feel.

[0056] By setting the high-speed brushing machine, during the brushing process, at least seven brush structures 210 with a maximum rotation speed of not less than 2000 r / min continuously apply external forces such as patting and friction to the fabric 100. Since the maximum rotation speed of the brush structure 210 is high, the brushing effect on the fabric 100 is better. After the above production process, the fabric surface can be slightly raised to achieve the effect of "short, dense, velvety", thereby making the fabric 100 have an ultra-soft feel.

[0057] In this embodiment, the high-speed brushing machine includes a cloth feeding device, a brushing device, a cloth guiding device and a cloth discharging device. The cloth feeding device, the brushing device, the cloth guiding device and the cloth discharging device are all provided with a tension adjusting device to adjust the tension of the fabric 100, so as to adjust the tension of the fabric 100 when the high-speed brushing machine feeds in the cloth, brushes the cloth and discharges the cloth. The greater the tension, the better the brushing effect. However, excessive tension may also lead to reduced physical properties such as the bursting force of the fabric 100, and fabric quality problems such as holes. Therefore, the adjustment of tension is more important for the performance of the fabric 100.

[0058] Specifically, the high-speed brushing machine also includes a control panel, on which various parameters are set, including cloth-in tension, cloth-out tension, brush tension, and cloth-playing tension, etc. By setting the cloth-in tension, the cloth-in tension of the fabric 100 can be adjusted through the tension adjusting device at the cloth-in device; by setting the cloth-out tension, the cloth-out tension of the fabric 100 can be adjusted through the tension adjusting device at the cloth-out device; by setting the brush tension and the cloth-playing tension, the brush tension and the cloth-playing tension of the fabric 100 can be adjusted through the tension adjusting device at the brush device.

[0059] Optionally, the above parameters also include parameters such as the rotation speed of the drum 220 , the rotation speed of the brush structure 210 , and the machine speed (the output length of the fabric 100 per minute of the high-speed brushing machine), which are all important parameters for brushing the fabric 100 .

[0060] Furthermore, the brush device includes the above-mentioned at least seven brush structures 210 and the big drum 220. At least seven brush structures 210 are arranged in the big drum 220 at circumferential intervals. The big drum 220 can rotate around the axis. At least seven brush structures 210 can rotate and revolve around the big drum 220, so as to realize brushing the cloth surface of the fabric 100 passing through the brush device.

[0061] Optionally, at least seven brush structures 210 can be specifically divided into a first brush group and a second brush group, the first brush group includes at least three first brushes 211, the second brush group includes at least three second brushes 212, the first brushes 211 and the second brushes 212 are arranged adjacent to each other, that is, the two brush structures 210 adjacent to each first brush 211 are both second brushes 212, and the two brush structures 210 adjacent to each second brush 212 are both first brushes. In addition, the first brush group and the second brush group are both provided with a driving structure, so that the brushing treatment of the fabric surface of the fabric 100 is relatively uniform.

[0062] In this embodiment, the method of brushing the dyed fabric 100 by a high-speed brushing machine in the above step S3 includes single-sided brushing or double-sided brushing, where single-sided brushing means brushing only one side of the fabric 100, and double-sided brushing means brushing both sides of the fabric 100. It can be understood that the brushing method of the fabric 100, single-sided brushing or double-sided brushing, can be adaptively changed according to actual needs, and is not specifically limited here.

[0063] Specifically, when single-sided brushing is performed, step S3 includes: brushing the first side of the dyed fabric 100 by a high-speed brushing machine to make the first side soft, thereby obtaining a single-sided soft fabric 100 .

[0064] When double-sided brushing is performed, the above step S3 includes:

[0065] S31: brushing the first side of the dyed fabric 100 by a high-speed brushing machine to make the first side soft, thereby obtaining a single-side soft fabric 100;

[0066] S32: brushing the second side of the single-sided soft fabric 100 with a high-speed brushing machine to make the second side soft, thereby obtaining a double-sided soft fabric 100.

[0067] The brushing method in this embodiment adopts a double-sided brushing method for the fabric 100 with high stitch count, high-density fabric, and ultra-fine fiber. The double-sided brushing method is more likely to achieve a soft hand feel and can significantly improve the creases of the fabric 100.

[0068] Specifically, in step S3, when the dyed fabric 100 is brushed by the high-speed brushing machine, the rotation speed of the drum 220 is too high, which will affect the increase of the self-rotation speed of the brush structure 210, and the energy consumption is increased too much, but the brushing effect is limited, so the rotation speed of the drum 220 cannot be too high. The lower the rotation speed of the drum 220, the better the velvet, but at the same time, the destructive force on the fabric surface is increased, and the self-rotation speed of the brush structure 210 is also reduced, thereby affecting the brushing effect. Therefore, the setting range of the rotation speed of the drum 220 of the high-speed brushing machine is 10r / min-35r / min.

[0069] Furthermore, in step S3, when the dyed fabric 100 is brushed by a high-speed brushing machine, the rotation speed of the brush structure 210 of the high-speed brushing machine is not less than 800 r / min, which can ensure a good degree of hairiness, and the higher the rotation speed, the better the hairiness. The maximum rotation speed of the brush structure 210 of the high-speed brushing machine in this embodiment is 2000 r / min, so the setting range of the rotation speed of the brush structure 210 is 800 r / min-2000 r / min.

[0070] Furthermore, the setting range of the bristle tension of the high-speed brushing machine is 15kg-30kg. The greater the bristle tension, the higher the hairiness. After the bristle tension is input into the preset value at the high-speed brushing machine, the high-speed brushing machine will adjust the tension of the fabric 100 by adjusting the tension adjustment device in the brushing device. Preferably, the bristle tension is 20kg.

[0071] Preferably, when brushing the first side in step S31, the cloth inlet tension of the high-speed brushing machine is set to 10kg, the cloth outlet tension is set to 12kg, the front brush tension is set to 20kg, the rear brush tension is set to 22kg, the rotation speed of the drum 220 is set to 12r / min, the cloth swing tension is set to 5kg, the machine speed is set to 30m / min, and the rotation speed of the brush structure 210 is set to 1800r / min, which is also 90% of the maximum rotation speed of the structure (since the parameter setting of the high-speed brushing machine is set by percentage, the maximum rotation speed of the brush structure 210 is set to A, therefore, the percentage multiplied by A below is the rotation speed of the brush structure 210). That is, the above parameters are adjusted through the control panel to achieve the optimal effect of brushing the first side of the fabric 100.

[0072] Since the brushing of the first side of the fabric 100 has been completed in step S31, the brushing of the first side can also improve the softness of the second side. Therefore, when brushing the second side, the settings of various parameter values ​​can be appropriately changed to make the softness of both sides of the fabric 100 have the same effect.

[0073] Further optionally, when brushing the second side in step S32, the cloth inlet tension of the high-speed brushing machine is set to 10kg, the cloth outlet tension is set to 12kg, the front brush tension is set to 18kg, the rear brush tension is set to 20kg, the drum 220 speed is set to 15r / min, the cloth swing tension is set to 5kg, the machine speed is set to 30m / min, and the rotation speed of the brush structure 210 is set to 1500r / min, which is also 75% of the maximum rotation speed of the structure. That is, the above parameters are adjusted through the control panel to achieve the optimal effect of brushing the second side of the fabric 100.

[0074] The process parameters of the brushing are set to the optimal parameter values. By setting the parameter values, the short density and softness of the fabric 100 after brushing are optimized.

[0075] S4: Finished product shaping: The brushed fabric 100 passes through the clean water in the slurry tank of the shaping machine head, and then is pressed by the uniform pressure roller, and finally enters the cabinet for drying and shaping to obtain the finished fabric 100. Specifically, the fabric 100 is pressed after passing through the clean water, which is conducive to maintaining the stability of the fabric surface specifications. At the same time, since the finished product can be shaped only by clean water, the step of adding silicone soft oil to soften is eliminated, which can improve the environmental protection and safety of the fabric 100 made by this method to the human body. Moreover, this velvet and softness are obtained by high-speed brushing instead of adding silicone soft oil, and it is very washable.

[0076] Furthermore, when the fabric 100 is being finalized, functional additives such as moisture absorption may be added to the clean water to improve the sweat absorption and moisture discharge properties of the fabric 100.

[0077] Experiments have shown that the fabric 100 produced by the method for producing soft fabrics in this embodiment still has good velvet and excellent softness after being washed 20 times by the method in AATCC135-2018.

[0078] The method for making the soft fabric of this embodiment reduces the use of a large amount of water, additives and chemicals in the process of making the fabric 100, simplifies the production steps, makes the processing more convenient, and makes the production process more energy-saving and environmentally friendly. In addition, the fabric 100 made by this solution is highly environmentally friendly, has a high degree of softness, and will not deform after multiple washings. Its own softness and other properties are maintained as before, and it has good anti-pilling performance, and can also reduce the creases of the fabric 100, ensuring that the clothes made of the fabric 100 can be worn for a long time.

[0079] Please refer to Figure 3 The following will select the brushing parameters of the high-speed brushing machine containing 9 brush structures 210 in this embodiment to be compared with other control embodiments. The specific comparison results are as follows: Figure 3 shown.

[0080] Among them, the fabric 100 manufactured by the steps in this embodiment and the high-speed brushing machine using the optimal parameters has an excellent softness, short and dense fluff, is more beautiful and neat, and its bursting force (the bursting force is the force applied vertically to the fabric 100 to break the fabric 100, the higher the bursting force, the less damage the fabric 100 suffers during the production process) is also higher than the demand.

[0081] Comparative Example 1 is an ordinary brushing machine with a maximum rotation speed of 1200r / min for the brush structure 210. Comparative Example 1 is an ordinary brushing machine with 6 brush structures 210 and a maximum rotation speed of 1200r / min, and its equipment selection parameters are the same as those of this embodiment. By comparing the softness and the bursting force, it can be seen that its softness is poor and the bursting force is high, while the fabric 100 of this embodiment has a high velvet degree and the bursting force also meets the minimum requirement.

[0082] Through the comparison with the above-mentioned control example 1, it can be concluded that the fabric 100 made by the method for making the soft fabric in this embodiment has excellent softness, is not easy to be damaged, and has good quality.

[0083] Furthermore, the machines used in the control examples 2-12 are all high-speed brushing machines containing 9 brush structures 210 and having a maximum rotation speed of up to 2000 r / min, and this setting is the same as that of the present embodiment.

[0084] Specifically, the control example 2 is a high-speed brushing machine containing 9 brush structures 210 and having a maximum rotation speed of 2000r / min. The difference between the parameters of the equipment selection and the present embodiment is that the rotation speed of the drum 220 when brushing the first side is 8r / min; the rotation speed of the drum 220 when brushing the second side is 10r / min, which is reduced compared with the rotation speed of the drum 220 of the present embodiment. By comparing the softness and the explosive force, it can be seen that the softness can reach excellent, but the explosive force is low and fails to meet the requirements, while the softness of the fabric 100 of the present embodiment can reach excellent, and the explosive force also meets the minimum requirements. It shows that if the rotation speed of the drum 220 is reduced, the explosive force of the fabric 100 made by the method for making the soft fabric in the present embodiment will be reduced.

[0085] The difference between the equipment selection parameters in the comparative example 3 and the present embodiment is that the speed of the drum 220 is set to 15r / min when brushing the first side, and the speed of the drum 220 is set to 18r / min when brushing the second side, which is higher than that of the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is good, the bursting force is slightly higher than that of the present embodiment, and the softness of the fabric 100 of the present embodiment is excellent.

[0086] The difference between the equipment selection parameters in the comparative example 4 and the present embodiment is that the speed of the drum 220 is set to 20r / min when brushing the first side, and the speed of the drum 220 is set to 23r / min when brushing the second side, which is further increased compared with the present embodiment and the comparative example 4. By comparing the softness and the bursting force, it can be seen that the softness is average, the bursting force is slightly higher than that of the comparative example 3, and the softness of the fabric 100 of the present embodiment is excellent.

[0087] The above two comparison examples can show that if the rotation speed of the drum 220 continues to increase, the softness of the fabric 100 manufactured by the method for manufacturing a soft fabric in this embodiment will be reduced.

[0088] The above three comparison examples show that the rotation speed of the bass drum 220 in this embodiment is the optimal rotation speed of the bass drum 220 .

[0089] Furthermore, the control example 5 is a high-speed brushing machine with 9 brush structures 210 and a maximum rotation speed of 2000r / min. The difference between the parameters of the equipment selection and the present embodiment is that the front brush tension is set to 22kg and the rear brush tension is set to 24kg when brushing the first surface; the front brush tension is set to 20kg and the rear brush tension is set to 22kg when brushing the second surface, which is higher than the brush tension of the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is excellent, but the bursting force does not meet the requirements, while the softness of the fabric 100 of the present embodiment can reach excellent, and the bursting force is much higher than that of the control example 5, and meets the requirements.

[0090] The difference between the parameters selected by the equipment in the comparative example 6 and the present embodiment is that the front bristle tension is set to 24kg and the rear bristle tension is set to 26kg when brushing the first surface, and the front bristle tension is set to 22kg and the rear bristle tension is set to 24kg when brushing the second surface, which is higher than the bristle tension of the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is excellent, but the bursting force is much lower than that of the present embodiment, and does not meet the requirements.

[0091] The above two control examples show that if the bristle tension continues to increase, the bursting force of the fabric 100 made by the method for making the soft fabric in this embodiment will be reduced.

[0092] The difference between the parameters selected by the equipment in the comparative example 7 and the present embodiment is that the front bristle tension is set to 18kg and the rear bristle tension is set to 20kg when brushing the first surface, and the front bristle tension is set to 16kg and the rear bristle tension is set to 18kg when brushing the second surface, which is lower than the bristle tension of the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is good, the bursting force is slightly higher than that of the present embodiment, and the softness of the fabric 100 of the present embodiment is excellent.

[0093] The difference between the equipment selection parameters in comparative example 8 and the present embodiment is that the front bristle tension is set to 16kg and the rear bristle tension is set to 18kg when brushing the first surface, and the front bristle tension is set to 14kg and the rear bristle tension is set to 16kg when brushing the second surface, which is further reduced compared with the bristle tension of the present embodiment and comparative example 7.

It shows that if the rotation speed of the brush structure 210 continues to increase, the bursting force of the fabric 100 made by the method for making the soft fabric in the present embodiment will not meet the requirements.

[0097] The difference between the parameters selected for the equipment in the comparative example 10 and the present embodiment is that the rotation speed of the brush structure 210 when brushing the first surface is set to 80%A, i.e., 1600r / min, and the rotation speed of the brush structure 210 when brushing the second surface is set to 60%A, i.e., 1200r / min, which is lower than the rotation speed of the brush structure 210 in the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is good, the bursting force is slightly higher than that in the present embodiment, and the softness of the fabric 100 in the present embodiment is excellent. This shows that if the rotation speed of the brush structure 210 continues to decrease, the softness of the fabric 100 made by the method for making soft fabric in the present embodiment will decrease.

[0098] The above two comparison examples can show that the parameters of the rotation speed of the brush structure 210 selected by the equipment in this embodiment are optimal values.

[0099] The difference between the equipment parameters selected in the comparative example 11 and the present embodiment is that the machine speed is set to 35 m / min when brushing the first side and 35 m / min when brushing the second side, which is higher than the machine speed of the present embodiment. By comparing the softness and the bursting force, it can be seen that the softness is good and the bursting force is high, while the softness of the fabric 100 of the present embodiment is excellent.

[0100] The difference between the equipment selection parameters in comparative example 12 and the present embodiment is that the machine speed is set to 40 m / min when brushing the first side and 40 m / min when brushing the second side, which is further increased compared with the present embodiment and comparative example 11. By comparing the softness and the bursting force, it can be seen that the softness is average, and the bursting force is higher than that of the present embodiment and comparative example 11, while the softness of the fabric 100 of the present embodiment is excellent.

[0101] The above two comparative examples show that if the machine speed continues to increase, the softness of the fabric 100 produced by the method for producing soft fabric in this embodiment will decrease. The machine speed parameter selected by the equipment in this embodiment is the optimal value.

[0102] By comparing the above comparative examples 1-12 with the present embodiment, it can be concluded that the fabric 100 manufactured by the manufacturing method of the soft fabric in the present embodiment has higher softness, better fluffiness, and the bursting force can better meet customer needs.
