[0002] Fibers can be mainly divided into three categories: natural fibers, synthetic fibers and man-made fibers. Natural fibers include plant fibers, animal fibers and mineral fibers, such as cotton, linen, wool, rabbit hair, silk, etc.; synthetic fibers are polymers of chemical raw material monomers, which are melts with spinnability and are produced by spinning; man-made fibers are the reconstruction and chemical treatment of plant fibers. Since different fibers have different properties, it is crucial to consider the differences in fiber properties in the preparation process of fiber textile fabrics in order to improve the quality of fiber textile fabrics.

[0003] Chinese Patent Publication No.: CN116575209A discloses a textile fabric processing equipment and a textile fabric processing process, including a workbench and a feeding roller and a receiving roller rotatably mounted at both ends of the workbench, two mounting frames are symmetrically mounted on the upper end of the workbench, support mechanisms are slidably mounted on the inner sides of the two mounting frames, a steam box is slidably connected between the two mounting frames, and a lifting mechanism for lifting the support mechanism and the steam box is fixedly mounted on the inner sides of the two mounting frames, a voltage stabilizing mechanism is arranged at the lower end of the workbench, and the steam box is connected to a steam generator through the voltage stabilizing mechanism, so that the fabric and the steam box are separated by a layer of cloth to avoid water droplets remaining on the fabric, and the fabric becomes flat as it is squeezed by the steam box and the layer of cloth, so that the fabric is reduced from being scalded and having spots, thereby improving the aesthetic feeling of the fabric.

[0004] However, there are still the following problems in the prior art:

[0005] In the prior art, the differences in water absorption properties of fiber textile fabrics made of different fibers are not taken into account, and thus the fiber textile fabrics are not properly treated, resulting in the fiber textile fabrics being easily shrunk during actual use and having poor quality, and no consideration is given to testing areas of the fiber textile fabric with different texture tightness. Summary of the invention

[0006] To this end, the present invention provides a fiber textile cloth for making textiles and a preparation method thereof, so as to overcome the problem that differences in water absorption properties of fiber textile cloths made of different fibers are not taken into consideration, and thus the fiber textile cloths are not properly treated, resulting in the fiber textile cloths being easy to shrink during actual use and having poor quality, and the problem that detection of areas with different texture tightness of the fiber textile cloths is not considered.

[0007] To achieve the above object, the present invention provides a method for preparing a fiber woven fabric for making textiles, comprising:

[0008] Step S1, pre-treating the fiber raw material, and putting the fiber raw material into a textile machine to obtain a fiber textile fabric;

[0009] Step S2, acquiring the image of the fiber textile fabric by an image acquisition device, acquiring the glossiness of the fiber textile fabric by a photometric measurement device, spraying a preset amount of water on the fiber textile fabric to acquire the image of the fiber textile fabric after absorbing water and the glossiness of the fiber textile fabric after absorbing water;

[0010] Step S3, obtaining, by an image processing device, a texture similarity value between the image of the fiber textile fabric and the image of the fiber textile fabric after absorbing water, and combining the gloss difference between the gloss of the fiber textile fabric and the gloss of the fiber textile fabric after absorbing water to calculate a water absorption characterization value, and classifying the water absorption category of the fiber textile fabric;

[0011] Step S4, selecting a treatment method according to the water absorption category of the fiber textile fabric, including:

[0012] Performing pre-shrinkage on the fiber textile fabric, calculating pre-shrinkage parameters according to the difference in tensile strength of the fiber textile fabric before and after pre-shrinkage and the change in area of ​​the fiber textile fabric, determining whether to perform leveling on the fiber textile fabric according to the pre-shrinkage parameters, and adjusting the leveling temperature and the leveling pressure;

[0013] Characteristic texture areas are identified according to the texture density values ​​of each area of ​​the fiber textile fabric, and an elastic stretch test is performed on the characteristic texture areas to obtain the length change of the characteristic texture areas before and after the test, and whether the fiber textile fabric meets the standards is determined according to the difference in length change between the characteristic texture areas.

[0014] Furthermore, in step S3, the water absorption characteristic value is calculated according to formula (1):

[0015]

[0016] In formula (1), X represents the water absorption characteristic value, S represents the texture similarity value, and S 0 represents the preset texture similarity threshold, L represents the glossiness difference, and L 0 Indicates the preset gloss difference threshold.

[0017] Furthermore, in step S3, the water absorption characteristic value is compared with a preset water absorption characteristic value comparison threshold value.

[0018] If the water absorption characterization value is greater than the preset water absorption characterization value comparison threshold, the water absorption category of the fiber textile fabric is the easy expansion and deformation category;

[0019] If the water absorption characterization value is less than or equal to the preset water absorption characterization value comparison threshold, the water absorption category of the fiber textile fabric is a category that is not easy to expand and deform.

[0020] Furthermore, in step S4, a treatment method is selected according to the water absorption category of the fiber textile fabric, wherein:

[0021] If the water absorption category of the fiber textile fabric is the easy expansion and deformation category, the fiber textile fabric is pre-shrunk, and the pre-shrunk parameter is calculated according to the difference in tensile strength of the fiber textile fabric before and after the pre-shrunk and the change in the area of ​​the fiber textile fabric, and it is determined whether to perform a flattening treatment on the fiber textile fabric according to the pre-shrunk parameter, and the flattening temperature and the flattening pressure are adjusted;

[0022] If the water absorption category of the fiber textile fabric is that it is not easy to swell and deform, the characteristic texture area is identified according to the texture density value of each area of ​​the fiber textile fabric, and the elastic stretching test is performed on the characteristic texture area to obtain the length change of the characteristic texture area before and after the test, and it is determined whether the fiber textile fabric meets the standard according to the difference in length change between the characteristic texture areas.

[0023] Furthermore, in step S4, the pre-shrinkage parameter is calculated according to formula (2):

[0024]

[0025] In formula (2), Q represents the pre-shrinkage parameter, A represents the change in the area of ​​the fiber textile fabric, and A 0 represents the preset fiber textile fabric area change threshold, F represents the fiber textile fabric tensile strength difference, F 0 Indicates the preset fiber textile cloth tensile strength difference threshold.

[0026] Furthermore, in step S4, the pre-shrinkage parameter is compared with a preset pre-shrinkage parameter comparison threshold.

[0027] If the pre-shrinkage parameter is greater than the preset pre-shrinkage parameter comparison threshold, it is determined that the fiber textile fabric is to be flattened.

[0028] Furthermore, in the step S4, the leveling temperature and the leveling pressure are adjusted according to the pre-shrinkage parameters, wherein the pre-shrinkage parameters are positively correlated with the leveling temperature and the leveling pressure.

[0029] Further, in the step S4, the fiber textile fabric is divided into a plurality of regions of equal area, and the texture density value of each region of the fiber textile fabric is compared with a preset first texture density value comparison threshold and a preset second texture density value comparison threshold, wherein the preset first texture density value comparison threshold is less than the preset second texture density value comparison threshold, and the characteristic texture region includes a characteristic loose region and a characteristic dense region;

[0030] If the texture density value of the fiber textile fabric region is less than a preset first texture density value comparison threshold, the fiber textile fabric region is identified as a characteristic loose region;

[0031] If the texture density value of the fiber textile cloth region is greater than a preset second texture density value comparison threshold, the fiber textile cloth region is identified as a characteristic density region.

[0032] Furthermore, in step S4, the difference between the length change of the characteristic loose area before and after the test and the length change of the characteristic tight area before and after the test is obtained, and the difference between the length change of the characteristic loose area before and after the test and the length change of the characteristic tight area before and after the test is compared with a preset difference comparison threshold.

[0033] If the difference between the length change before and after the characteristic loose area test and the length change before and after the characteristic tight area test is greater than the preset difference comparison threshold, it is determined that the fiber textile fabric does not meet the standard.

[0034] A fiber woven cloth for making textiles is made according to the fiber woven cloth preparation method described above.

[0035] Compared with the prior art, the present invention puts fiber raw materials into a textile machine to obtain a fiber textile cloth; obtains texture similarity values ​​and glossiness differences before and after spraying a preset amount of water on the fiber textile cloth to calculate a water absorption characterization value, and divides the fiber textile cloth into water absorption categories; performs pre-shrinkage on the fiber textile cloth, calculates pre-shrinkage parameters according to the difference in tensile strength and area change of the fiber textile cloth before and after pre-shrinkage, and determines whether to perform leveling on the fiber textile cloth; identifies characteristic texture areas according to texture tightness values ​​of various areas of the fiber textile cloth, performs elastic stretching tests on the characteristic texture areas, and determines whether the fiber textile cloth meets the standards according to the length change difference between the characteristic texture areas. The present invention improves the dimensional stability of the fiber textile cloth by preventing the fiber textile cloth from shrinking during use, thereby improving the quality of the fiber textile cloth.

[0036] In particular, the present invention calculates the water absorption characterization value based on the texture similarity value and the glossiness difference value of the fiber textile fabric. The texture similarity value and the glossiness difference value of the fiber textile fabric before and after water absorption are important parameters for characterizing the water absorption of the fiber textile fabric. When the water absorption of the fiber textile fabric is strong, the fiber raw material of the fiber textile fabric swells due to water absorption, so that the texture of the fiber textile fabric may undergo irregular deformation. The lower the texture similarity before and after the fiber textile fabric absorbs water, the stronger the water absorption of the fiber textile fabric can be characterized to a certain extent. After the fiber textile fabric absorbs water, the fiber raw material absorbs water and swells, and the area of ​​light reflection increases, thereby improving the glossiness of the fiber textile fabric. The larger the glossiness difference value before and after the fiber textile fabric absorbs water, the stronger the water absorption of the fiber textile fabric can be characterized to a certain extent. By calculating the water absorption characterization value, the water absorption of the fiber textile fabric can be characterized to a certain extent, which is helpful for subsequent processing of the fiber textile fabric and improving the quality of the fiber textile fabric.

[0037] In particular, the present invention determines whether to perform a leveling treatment on the fiber textile fabric according to the preshrinkage parameters, and adjusts the leveling temperature and the leveling pressure. The fiber textile fabric with strong water absorption is prone to become smaller in size during actual use. The fiber textile fabric with strong water absorption is pre-shrunk in advance. When the size of the fiber textile fabric becomes smaller, the texture of the fiber textile fabric is easily deformed, resulting in wrinkles and unevenness on the surface of the fiber textile fabric. The difference in tensile strength before and after preshrinkage of the fiber textile fabric and the change in the area of ​​the fiber textile fabric can to a certain extent characterize the influence of the preshrinkage treatment on the fiber textile fabric. When the influence is large, the surface of the fiber textile fabric is more likely to become uneven, so the fiber textile fabric needs to be leveled to improve the quality of the fiber textile fabric.

[0038] In particular, the present invention determines whether the fiber textile fabric meets the standards based on the difference in length changes between characteristic texture areas. There are differences in texture density values ​​in various areas of the fiber textile fabric, and there may be differences in elastic recovery capabilities between areas with larger texture density values ​​and areas with smaller texture density values, resulting in deformation of the fiber textile fabric during use. By performing elastic stretching tests to obtain the recovery capabilities of areas with different texture density values, a certain judgment can be made on the quality of the fiber textile fabric.

Figure 4 This is a logic determination diagram of whether to perform flattening treatment on a fiber textile fabric according to an embodiment of the invention. The fiber textile fabric preparation method for making textiles of the present invention comprises:

[0046] Step S1, pre-treating the fiber raw material, and putting the fiber raw material into a textile machine to obtain a fiber textile fabric;

[0047] Step S2, acquiring the image of the fiber textile fabric by an image acquisition device, acquiring the glossiness of the fiber textile fabric by a photometric measurement device, spraying a preset amount of water on the fiber textile fabric to acquire the image of the fiber textile fabric after absorbing water and the glossiness of the fiber textile fabric after absorbing water;

[0048] Step S3, obtaining, by an image processing device, a texture similarity value between the image of the fiber textile fabric and the image of the fiber textile fabric after absorbing water, and combining the gloss difference between the gloss of the fiber textile fabric and the gloss of the fiber textile fabric after absorbing water to calculate a water absorption characterization value, and classifying the water absorption category of the fiber textile fabric;

[0049] Step S4, selecting a treatment method according to the water absorption category of the fiber textile fabric, including:

[0050] Performing pre-shrinkage on the fiber textile fabric, calculating pre-shrinkage parameters according to the difference in tensile strength of the fiber textile fabric before and after pre-shrinkage and the change in area of ​​the fiber textile fabric, determining whether to perform leveling on the fiber textile fabric according to the pre-shrinkage parameters, and adjusting the leveling temperature and the leveling pressure;

[0051] Characteristic texture areas are identified according to the texture density values ​​of each area of ​​the fiber textile fabric, and an elastic stretch test is performed on the characteristic texture areas to obtain the length change of the characteristic texture areas before and after the test, and whether the fiber textile fabric meets the standards is determined according to the difference in length change between the characteristic texture areas.

[0052] Specifically, the present invention does not limit the way in which the fiber raw materials are pretreated. In this embodiment, the fiber raw materials are combed to remove short fibers and impurities in the fibers, making the fibers more parallel and neat, and having better fiber length consistency. This is a prior art and will not be described in detail.

[0053] Specifically, the present invention does not limit the specific structure of the image acquisition device. In this embodiment, preferably, the image acquisition device is an industrial camera, which only needs to be able to acquire high-definition fiber textile cloth images.

[0054] Specifically, the present invention does not limit the specific structure of the photometric measuring device. In this embodiment, preferably, the photometric measuring device is a gloss meter, which obtains the glossiness of the surface of the fiber textile cloth based on the reflection and refraction of light. This is a prior art and will not be described in detail.

[0055] Specifically, the present invention does not limit the specific structure of the image processing device, and can use AdobePhotoshop, OpenCV, MATLAB and other image processing software to perform similarity value analysis on the fiber textile fabric texture and obtain the fiber textile fabric texture density value. In the present invention, the fiber textile fabric texture density value is the number of yarns per unit area. This is the prior art and will not be repeated here.

[0056] Specifically, in step S3, the water absorption characteristic value is calculated according to formula (1):

[0057]

[0058] In formula (1), X represents the water absorption characteristic value, S represents the texture similarity value, and S 0 represents the preset texture similarity threshold, L represents the glossiness difference, and L 0 Indicates the preset gloss difference threshold.

[0059] In this embodiment, S 0 Select in [0.9, 0.95], L 0 For the purpose of pre-measurement of the experiment, the gloss difference of several fiber textile fabrics before and after water absorption is obtained in advance, and the average value Le is calculated. It is assumed that L0=k×Le, 1.1<k<1.3, and k is the gloss difference coefficient.

[0060] Specifically, the present invention calculates the water absorption characterization value based on the texture similarity value and the glossiness difference value. The texture similarity value and the glossiness difference value before and after the fiber textile fabric absorbs water are important parameters for characterizing the water absorption of the fiber textile fabric. When the fiber textile fabric has strong water absorption, the fiber raw material of the fiber textile fabric swells due to water absorption, so that the texture of the fiber textile fabric may undergo irregular deformation. The lower the texture similarity before and after the fiber textile fabric absorbs water, the stronger the water absorption of the fiber textile fabric can be characterized to a certain extent. After the fiber textile fabric absorbs water, the fiber raw material absorbs water and swells, and the area of ​​light reflection increases, thereby improving the glossiness of the fiber textile fabric. The greater the glossiness difference value before and after the fiber textile fabric absorbs water, the stronger the water absorption of the fiber textile fabric can be characterized to a certain extent. By calculating the water absorption characterization value, the water absorption of the fiber textile fabric can be characterized to a certain extent, which is helpful for subsequent processing of the fiber textile fabric, thereby improving the quality of the fiber textile fabric.

[0061] Specifically, in step S3, the water absorption characteristic value is compared with a preset water absorption characteristic value comparison threshold value.

[0062] If the water absorption characterization value is greater than the preset water absorption characterization value comparison threshold, the water absorption category of the fiber textile fabric is the easy expansion and deformation category;

[0063] If the water absorption characterization value is less than or equal to the preset water absorption characterization value comparison threshold, the water absorption category of the fiber textile fabric is a category that is not easy to expand and deform.

[0064] In this embodiment, the preset water absorption characterization value comparison threshold is selected from [2.5, 3].

[0065] Specifically, in step S4, a treatment method is selected according to the water absorption type of the fiber textile fabric, wherein:

[0066] If the water absorption category of the fiber textile fabric is the easy expansion and deformation category, the fiber textile fabric is pre-shrunk, and the pre-shrunk parameter is calculated according to the difference in tensile strength of the fiber textile fabric before and after the pre-shrunk and the change in the area of ​​the fiber textile fabric, and it is determined whether to perform a flattening treatment on the fiber textile fabric according to the pre-shrunk parameter, and the flattening temperature and the flattening pressure are adjusted;

[0067] If the water absorption category of the fiber textile fabric is that it is not easy to swell and deform, the characteristic texture area is identified according to the texture density value of each area of ​​the fiber textile fabric, and the elastic stretching test is performed on the characteristic texture area to obtain the length change of the characteristic texture area before and after the test, and it is determined whether the fiber textile fabric meets the standard according to the difference in length change between the characteristic texture areas.

[0068] Specifically, the present invention does not limit the specific method of pre-shrinkage treatment. The pre-shrinkage treatment includes heating the fiber textile fabric after washing. The purpose of pre-shrinkage treatment of the fiber textile fabric is to reduce the size change of the fiber textile fabric during actual use or washing. This is a prior art and will not be repeated here.

[0069] Specifically, the present invention does not limit the specific method of obtaining the tensile strength value of the fiber textile fabric. Since the texture of the fiber textile fabric becomes tighter after pre-shrinkage treatment, the tighter texture will increase the tensile strength value of the fiber textile fabric. In this embodiment, optionally, the fiber textile fabric is stretched to a preset length by a force sensor to obtain the tensile value of the force sensor.

[0070] Specifically, in step S4, the pre-shrinkage parameter is calculated according to formula (2):

[0071]

[0072] In formula (2), Q represents the pre-shrinkage parameter, A represents the change in the area of ​​the fiber textile fabric, and A 0 represents the preset fiber textile fabric area change threshold, F represents the fiber textile fabric tensile strength difference, F 0 Indicates the preset fiber textile cloth tensile strength difference threshold.

[0073] In this embodiment, A 0 , F 0 Through experiments, several fiber textiles are obtained in advance for pre-shrinkage treatment, and the average fiber textile tensile force difference Fe and the average fiber textile area change Ae of each fiber textile before and after pre-shrinkage are obtained. Let A 0 =a×Ae, a is the area change coefficient, 1.2<a<1.4, let F 0 =b×Fe, b is the tensile strength difference coefficient, 1.1<b<1.2.

[0074] Specifically, in step S4, the pre-shrinkage parameter is compared with a preset pre-shrinkage parameter comparison threshold.

[0075] If the pre-shrinkage parameter is greater than the preset pre-shrinkage parameter comparison threshold, it is determined that the fiber textile fabric is to be flattened.

[0076] In this embodiment, the preset pre-shrinkage parameter comparison threshold is selected from [1, 1.2].

[0077] Specifically, in the step S4, the flattening temperature t and the flattening pressure F are adjusted according to the pre-shrinking parameter, wherein the pre-shrinking parameter is positively correlated with the flattening temperature and the flattening pressure.

[0078] In this embodiment, optionally,

[0079] 1.2<Q<1.4, t1=t0+Δt1, F1=F 0 +ΔF1;

[0080] 1.4≤Q, t2=t0+Δt2, F2=F 0 +ΔF2.

[0081] t0 is the initial leveling temperature, Δt1 is the first leveling temperature adjustment, Δt2 is the second leveling temperature adjustment, F 0 is the initial leveling pressure, ΔF1 is the first leveling pressure adjustment, ΔF2 is the second leveling pressure adjustment, 0.1t0≤Δt1<Δt2≤0.25t0, 0.15F 0 ≤ΔF1<ΔF2≤0.25F 0 .

[0082] Specifically, the present invention determines whether to perform a leveling treatment on the fiber textile fabric according to the preshrinkage parameters, and adjusts the leveling temperature and the leveling pressure. The fiber textile fabric with strong water absorption is prone to become smaller in size during actual use. The fiber textile fabric with strong water absorption is pre-shrunk in advance. When the size of the fiber textile fabric becomes smaller, the texture of the fiber textile fabric is easily deformed, resulting in wrinkles and unevenness on the surface of the fiber textile fabric. The difference in tensile strength before and after preshrinkage of the fiber textile fabric and the change in the area of ​​the fiber textile fabric can to a certain extent characterize the influence of the preshrinkage treatment on the fiber textile fabric. When the influence is large, the surface of the fiber textile fabric is more likely to become uneven, so the fiber textile fabric needs to be leveled to improve the quality of the fiber textile fabric.

[0083] Specifically, the present invention does not limit the specific method of the elastic stretching test. In this embodiment, the edge of the characteristic texture area of ​​the fiber textile fabric can be clamped oppositely and stretched to a predetermined length and maintained for a predetermined time.

[0084] Specifically, in step S4, the fiber textile fabric is divided into a plurality of regions of equal area, and the texture density value of each region of the fiber textile fabric is compared with a preset first texture density value comparison threshold and a preset second texture density value comparison threshold, wherein the preset first texture density value comparison threshold is less than the preset second texture density value comparison threshold, and the characteristic texture region includes a characteristic loose region and a characteristic dense region;

[0085] If the texture density value of the fiber textile fabric region is less than a preset first texture density value comparison threshold, the fiber textile fabric region is identified as a characteristic loose region;

[0086] If the texture density value of the fiber textile cloth region is greater than a preset second texture density value comparison threshold, the fiber textile cloth region is identified as a characteristic density region.

[0087] In this embodiment, the average value Me of the texture density value of each region of the fiber textile fabric is obtained in advance, the first texture density value comparison threshold M1=0.8Me is preset, and the second texture density value comparison threshold is preset as 1.2Me.

[0088] Specifically, in step S4, the difference between the length change of the characteristic loose area before and after the test and the length change of the characteristic tight area before and after the test is obtained, and the difference between the length change of the characteristic loose area before and after the test and the length change of the characteristic tight area before and after the test is compared with a preset difference comparison threshold.

[0089] If the difference between the length change before and after the characteristic loose area test and the length change before and after the characteristic tight area test is greater than the preset difference comparison threshold, it is determined that the fiber textile fabric does not meet the standard.

[0090] In this embodiment, the preset difference comparison threshold is selected from [0.03, 0.05].

[0091] Specifically, the present invention determines whether the fiber textile fabric meets the standard based on the difference in length change between characteristic texture areas. There are differences in texture density values ​​in various areas of the fiber textile fabric, and there may be differences in elastic recovery capabilities between areas with larger texture density values ​​and areas with smaller texture density values, resulting in deformation of the fiber textile fabric during use. By performing elastic stretching tests to obtain the recovery capabilities of areas with different texture density values, a certain judgment can be made on the quality of the fiber textile fabric.

[0092] A fiber woven cloth for making textiles is prepared according to the fiber woven cloth preparation method described above.

[0093] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
