Description
Technical Field
The invention relates to the field of fabric cleaning by machine vision, in particular to a method for marking hair on a flocked fabric.
Background
The flannelette of the flannelette fabric is generally made of polyester fibers and is made by the processes of napping and the like, and the produced cloth is soft and skin-friendly. The flannelette has soft body, is comfortable to wear, has good heat retention property, and is suitable for being used as underwear and pajamas in winter. Currently, there are a number of garments worn next to the skin that use a velvet material as the inner layer that directly contacts the skin.
However, the clothes made of flannelette materials are easy to stick human hair, broken hair, pet hair and other hair on the cloth surface. Hairs are easily entangled with the fleece material. It is difficult to completely remove the hairs embedded in the lint through ordinary machine washing or hand washing. When the hair embedded in the flannelette is contacted with the skin, the hair can stimulate the skin, generate itching feeling and influence the user experience. Especially some relatively hard hairs, such as cut hairs remaining on the clothing after haircut, which are typically within a few millimeters in length. After the hair such as broken hair contacts the flannelette, the broken hair is more easily fixed on the flannelette by electrostatic action, physical friction and the like compared with other fabrics due to the multi-velvet structure on the surface of the flannelette, and the hair is relatively more difficult to be removed by machine washing. And some hairs are inherently darker in color and are difficult to distinguish visually from many darker pile materials. The hair is not easy to be removed by machine washing or hand washing, and is difficult to be identified by manpower or machine vision, so that the follow-up removal by tools such as tweezers and viscose or automatic equipment is influenced.
Once a napped garment becomes soiled by hair, such as cut hair, the comfort of the garment is greatly compromised, and in particular for intimate fabrics, it is more directly irritating to the skin. If the hair is not identified in an effective mode, the hair is difficult to remove, such as broken hair, and the user is forced to buy new clothes again, which causes resource waste.
Disclosure of Invention
In order to solve the above problems, the present invention provides a method for marking hair on a pile fabric, comprising the steps of:
s1 pretreatment:
arranging a label at a designated position of the fabric and arranging standard hair on the fabric;
soaking the fabric in a solution with a pH value of 10 or above for a certain time;
washing the fabric with clear water until the pH value is neutral;
s2 staining
Selecting a strong acid dye which has obvious color difference with the color of the fabric;
dyeing the fabric by a selected strong acid dye dyeing process;
s3 post-processing
The fabric is subjected to water-washing treatment,
inspecting the dyed fabric, and identifying the standard broken hair at the position of the label arranged at the designated position of the dyed fabric in the pre-processing stage in a manual or machine vision mode to determine whether the standard broken hair reaches the degree of being detected manually or by machine vision
If the detected degree is reached, finishing the identification;
if the detection is not possible, the steps S2 and S3 are repeated.
The core principle of the invention is that the hair belongs to protein fiber, and can be dyed at low temperature by acid dye, the main body of the velvet fabric is synthetic fiber such as polyester, and the conventional dyeing can not be finished at low temperature, and the main body of the velvet fabric can not be dyed by the washing process after dyeing, thereby realizing that the hair color is changed into the color which is obviously different from the fabric color, and having the effect of being beneficial to distinguishing through machine vision.
Has the advantages that: the preprocessing step in the step S1 includes the steps of: and arranging labels at the designated positions, adding standard-length hairs and other markers for detecting the dyeing effect.
The marker is used for detecting the degree of staining so as to improve the time efficiency of the identification process, and the principle is as follows:
the marker is used for marking the position of the standard hair, and is prevented from being difficult to find and identify because the standard hair is too small.
In each dyeing process of the step S2, the dyeing time refers to the selected dyeing process of the strongly acidic dye, and the minimum dyeing treatment time recommended by the dyeing process is selected. After the treatment of the minimum dyeing time, if the dyeing effect of the standard hair reaches the degree that the standard hair can be distinguished by manual or machine vision, the hair marking can be completed in the minimum time. And in the step S3, the dyeing effect of other hairs on the whole fabric is deduced by detecting the dyeing condition of the standard hairs, and if the dyeing effect of the standard hairs is not good, the hairs are further dyed by repeatedly dyeing, so that the dyeing depth of the hairs is improved, and the color discrimination of the hairs and the fabric is increased.
When the machine vision deals with the hairs with different colors and shapes, a more complex algorithm is needed, and after the hairs are changed into the uniform color, the weight for distinguishing the colors can be increased when the machine vision identifies the hairs, the used algorithm is simpler, the difficulty in developing the algorithm and software is reduced, and the identification efficiency is improved.
The strength of the hair on the surface of the fabric treated by the acid-base treatment and the dyeing process is reduced, so that the subsequent cleaning easiness is further improved
The synthetic fiber surface of the fabric treated by the acid-base treatment and the dyeing process can also generate fine structure change and fine etching, and the fabric can improve the hygroscopicity of the fabric and increase the wearing comfort under the condition of not obviously influencing the structural strength of the fabric because of the structural change of the fiber surface.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Selecting a velvet fabric with a polyester material as a fabric, wherein the velvet fabric is dark blue, black hair is embedded in the velvet fabric,
s1 pretreatment:
arranging a label at a designated position of the fabric and adding standard hair; the label is selected from labels which can not lose the marking effect on the position of the standard hair in the treatment process. The standard hair is black hair with length of 1cm, and is embedded into the position of a pin needle head on the fabric. For the sake of representativeness, a plurality of labels can be arranged at different positions of the fabric, and a plurality of standard hairs can be correspondingly arranged.
Soaking the fabric in a solution with a pH value of 10 or above for a certain time; in the embodiment, the sodium carbonate solution with the pH value of 11 is selected and can be treated under the conditions from normal temperature to heating boiling, the heating treatment can improve the time efficiency, the treatment time is 30 minutes, and the sodium carbonate solution needs to be soaked for a longer time in normal temperature treatment. By using the alkaline solution for treatment, on one hand, substances such as grease and the like on the surface of hair and hindering dyeing can be removed, on the other hand, fine etching can be caused on the surface of the synthetic fiber of the fabric, the moisture absorption of the fabric is increased, and the wearing comfort is further improved.
Washing the fabric treated by the alkali with clear water until the pH value is neutral;
s2 staining
Dyeing the whole fabric by a strong acid dye dyeing process (refer to textbook dyeing and finishing process and principle);
the dyeing process selected in the embodiment is as follows:
the dye variety is as follows: acid orange II
Dye quality: 2 percent of the fabric mass
Dye bath pH: 2
Dye bath quality: 20 times of the fabric mass
Peregal O: 0.01 percent of the fabric mass
The dyeing time is 30 minutes, and the dyeing temperature is 90 ℃.
Removing loose color by soaping and washing after dyeing
For the selection of strongly acidic dye varieties, only dyes with obvious color difference with the color of the fabric of the ground color need to be selected, for example, for light-colored fabrics, dyes with darker and darker colors are selected, and for dark-colored fabrics, light-colored dyes with bright colors are selected.
The selection of the dyeing process needs to refer to the selected dye, the corresponding dyeing process recommended by the instruction manual of the selected dye is selected for dyeing, and in order to improve the time efficiency and the energy efficiency of dyeing, the shortest dyeing time and the lowest dyeing temperature in the dyeing process are preferred.
S3 post-processing
And inspecting the dyed fabric, and identifying whether the standard hair at the position of the label arranged at the designated position of the dyed fabric in the pre-treatment stage reaches the degree of being detected by manual or machine vision in a manual or machine vision mode. For detection in a machine vision mode, whether the machine vision detection can be performed or not is judged by counting the detection rate of the detected standard hairs of the machine which has completed artificial intelligence training.
In this case, the camera is used to collect the image data of the standard hairs on the fabric, and the manual distinguishing condition is recorded by using the scale, the scale sets 3 values of easy, medium and difficult degrees aiming at the distinguishing difficulty degree, and whether the hairs on the fabric can be detected is defined by counting the distinguishing difficulty degrees of a plurality of standard hairs on one fabric.
The difficulty of distinguishing the standard hairs on the sample fabric is counted, and the number of the standard hairs evaluated as 'easy to distinguish' is divided by the total number of the standard hairs on the sample fabric to obtain a percentage. When the difficulty of distinguishing statistically more than 90% of standard hairs is "easy to distinguish", most other non-standard hairs representing the surface of the tufted textile that need to be removed in a subsequent treatment are also distinguishable and therefore considered to be machine-visually detectable.
For samples that are considered to be detectable by machine vision, the image data acquired by the camera for the standard hairs on the fabric are marked as "easy", and then a training set is generated based on the marked images for algorithmic training of machine vision. And finishing the identification of the hair after the treatment.
If the difficulty level of distinguishing the standard hairs is "easy" which is less than 90%, it is determined that the standard hairs cannot be detected, and the steps S2 and S3 are repeated.
The above description is only a part of the embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
