Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile testing, in particular to a textile fiber shedding degree testing system. BACKGROUND

[0002] The problem of linting of textile fabrics, especially raised fabric and loose-structured textile fabrics, is still prominent. In recent years, driven by the pursuit of mass fashion, clothing fabrics have undergone some bold changes in terms of surface treatment, fiber composition, weaving process, and special style finishing. Products have shown a variety of diversity. However, in the pursuit of style, surface milling, reducing yarn twist, reducing weaving density, or using special finishing processes may be used to achieve the goal, but these processing methods often reduce the toughness of the fabric surface fibers, causing fiber breakage under external force, and thus linting.

[0003] Some products cause fiber to separate from the fabric during wear, resulting in linting. The shed fibers or lint adhering to the human skin or other clothing are difficult to remove, causing great dissatisfaction among consumers. Some products shed fibers or broken filaments during washing due to reduced yarn internal stress or insufficient twist, adhering to the washing basin, the hands of the washer, or the inner cavity of the washing machine, polluting other clothes, often causing more than one piece of clothing to the consumer.

[0004] For existing milling, light raising, cutting, flat, and looped pile fabrics, these pile products often have linting during wear and use, causing discomfort and visual impact to consumers. In order to determine the degree of linting of textiles, consumers generally use manual tapping and rubbing to determine the degree of linting.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0030] Embodiment one:

[0031] As shown in the accompanying drawings of the specification Figures 1-6 The present application provides a textile fiber shedding degree test system, which comprises a test machine body 1, a test sensor and a fixing assembly. The fixing assembly comprises a driving wheel 2 and a driven wheel 3. The surface of the driving wheel 2 is fixed with a sample to be tested, and the surface of the driven wheel 3 is covered with a transparent test adhesive tape. The driving wheel 2 and the driven wheel 3 are installed in a test area 12 formed between the side surface of the test machine body 1 and a soundproof cover 11, and the test machine body 1 is rotationally connected with the soundproof cover 11. The bottom of the test machine body 1 is uniformly provided with adjustable feet.

[0032] The driving wheel 2 is connected with the output end of a driving device on the side surface of the test machine body 1. The driving device can be an existing motor device, and the driving device is controlled by a controller. The driven wheel 3 is rotationally arranged on a fixing support 21 on the upper side of the driving wheel 2 and synchronously rotates under the driving of the driving wheel 2. The fixing support 21 is provided with a test sensor, which can be an existing pressure load cell. The test sensor is arranged on the fixing support 21 to collect weight change data of the driven wheel 3 during the test. An image acquisition camera 22 is arranged at the position of the fixing support 21 on the upper side of the driven wheel 3 to collect image information on the surface of the test adhesive tape.

[0033] Specific working process: For existing brushed, light pile, cut pile, flat pile, loop pile and other pile textiles, these pile products often have the phenomenon of shedding in the wearing and using process of consumers, which brings discomfort and very intuitive visual impact to consumers. In order to better test the fiber shedding degree related performance of these textiles, compared with the subjective judgment of the user by simple manual beating and rubbing, the present application provides a textile fiber shedding degree test system to realize more automatic and accurate testing of the fiber shedding degree of the textile to be tested.

[0034] Specifically, open the soundproof cover 11, fix the sample collected on the textile to be tested on the driving wheel 2, fix the test tape on the driven wheel 3, so that the surfaces of the driving wheel 2 and the driven wheel 3 are in contact with each other, the test tape is in contact with the surface of the sample to be tested, close the soundproof cover 11 to make the test area 12 in an approximately closed environment, start the driving device connected to the driving wheel 2 to make the driving wheel 2 rotate, the friction driving action makes the driven wheel 3 rotate synchronously, and the surface of the test tape on the driven wheel 3 is in full contact with the surface of the sample to be tested during rotation. The test tape adheres to the fibers on the surface of the sample to be tested that have a tendency to fall off and the fibers that are not firmly fixed, leaving the test tape surface;

[0035] After the above process continues for a period of time, the driving device is controlled to rotate in the opposite direction, and continues for a period of time. After the test is completed, the amount of fibers that have fallen off can be determined by analyzing the amount of fibers adhered to the surface of the test tape, and the degree of fiber shedding of the textile to be tested can be determined. The specific analysis method can be to measure the weight change of the driven wheel 3 before and after the test by the test sensor connected to the driven wheel 3 and the fixed support 21. After the test is completed, the test tape can be removed and weighed to calculate the weight of the fibers collected on the test tape. After collecting the weight data of the fibers that have fallen off from the sample to be tested, the data can be compared with the relevant standard of the degree of fiber shedding of the textile to determine the specific data of the degree of fiber shedding of the textile to be tested.

[0036] Alternatively, the method of visual detection can be used to collect the changes in the surface of the test tape during the test by the image acquisition camera 22 fixed on the fixed support 21, and the image data can be transmitted to the test personnel. The analysis can be performed by manual or visual analysis software. In this way, the density of the fibers that have fallen off and adhered to the surface of the test tape can be analyzed to determine the degree of fiber shedding of the textile to be tested.

[0037] In summary, the present application improves the accuracy and automation of the test by automatically testing the textile to be tested. The accuracy of the final test result is further improved by comprehensive analysis of various test results, which helps the processing personnel to better judge the quality of the textile to be tested.

[0038] Example Two

[0039] On the basis of example one, the sliding block structure of the fixed support 21 is slidably embedded in the adjusting groove 13 provided on the side of the test body 1, and the limiting rod 211 provided on the fixed support 21 is slidably embedded in the limiting hole 121 on the inner wall of the adjusting groove 13, and the limiting rod 211 is connected to the elastic element on the inner wall of the limiting hole 121. The elastic element can be a spring.

[0040] The fixed support 21 is provided with an L-shaped fixed rod 212 at the position on the upper side of the driven wheel 3, the image acquisition camera 22 is located at the lower surface of the horizontal position of the fixed rod 212, and the fixed rod 212 is also loaded with a weight loading weight 23 for adjusting the contact pressure between the driving wheel 2 and the driven wheel 3. The outer surface of the driven wheel 3 is provided with a pressure sensor.

[0041] Specific working process: on the basis of the specific working process in embodiment one, the fixed support 21 in the application is slidably embedded into the adjusting groove 13, which can be adjusted in the vertical direction, so that the distance and contact pressure between the driving wheel 2 and the driven wheel 3 can be adjusted as needed; specifically, after the textile sample to be tested and the test tape are fixed on the driving wheel 2 and the driven wheel 3 respectively, the weight loading weight 23 is stacked on the fixed rod 212 in sequence, so that the fixed rod 212 is driven to move downward with the fixed support 21 and the driven wheel 3 to contact the driving wheel 2 below. Different amounts of weight loading weights 23 correspond to the downward movement distance of the driven wheel 3, and the driven wheel 3 has different degrees of contact pressure with the driving wheel 2, and the pressure sensor on the side wall of the driven wheel 3 can measure the contact pressure between the driving wheel 2 and the driven wheel 3.

[0042] In this way, when testing the fiber shedding degree of the textile sample, multiple interconnected samples can be prepared, and different amounts of weight loading weights 23 are loaded in sequence to make the contact pressure between the driving wheel 2 and the driven wheel 3 change in a gradient, so as to fully collect the values of the fiber shedding degree of the textile to be tested under different contact pressures, analyze the relationship between the contact pressure and the fiber shedding degree, control the variables more accurately, improve the test conditions and variables, increase the data collection mode of the test sample, reduce the test error of the fiber shedding degree of the textile to be tested, and improve the precision of the test system of the application.

[0043] Embodiment three:

[0044] On the basis of embodiment two, a purification fan is arranged in the test body 1, and a purification hole 213 is arranged around the image acquisition camera 22 on the lower surface of the horizontal position of the fixed rod 212, and the purification hole 213 is communicated with the air outlet end of the purification fan through a flexible hose.

[0045] A collection cavity 4 is arranged at the bottom of the test area 12, and a collection groove 41 is arranged at the position directly below the driving wheel 2 on the upper surface of the bottom of the test area 12, and the collection groove 41 is communicated with the collection cavity 4. An interception layer 42 is arranged in the middle of the collection cavity 4, and the lower side area of the interception layer 42 is communicated with the air inlet end of the purification fan.

[0046] Specific workflow: on the basis of the specific workflow in embodiment two, during the test process, considering the air flow brought by the rotation of the driving wheel 2 and the driven wheel 3 and the inertial vibration effect, it is possible to cause the fibers that are partially detached from the sample to be tested to not adhere to the surface of the test tape, or to be detached from the surface of the test tape after adhering to the surface of the test tape, resulting in the scattered fiber debris inside the test area 12, which will reduce the amount of fibers collected on the test tape, and further reduce the test accuracy; and these dispersed fiber debris may adhere to the inner wall of the test area 12, or adhere to the surface of the image acquisition camera 22, interfering with the image acquisition work on the surface of the test tape, and increasing the workload of subsequent fiber debris cleaning work;

[0047] Therefore, the purification fan is arranged, after the purification fan is started, the purification airflow flows into the hollow area inside the fixed rod 212 along the flexible hose, and then flows out from the purification hole 213 around the working end of the image acquisition camera 22 on the lower surface of the fixed rod 212, forming an outward impact airflow, so that the airflow intensity around the working end of the image acquisition camera 22 is increased, preventing the fiber debris scattered inside the test area 12 from approaching and adhering to the upper side of the image acquisition camera 22, and ensuring the normal operation of the image acquisition camera 22;

[0048] Further, because the air suction end of the purification fan is communicated with the collection cavity 4 at the bottom, the purification airflow released from the purification hole 213 flows downward through the collection groove 41 at the bottom into the collection cavity 4, and the airflow is sucked into the air suction end, realizing the circulation of the purification airflow; and the downward flow path of the purification airflow covers the surface of the driving wheel 2 and the driven wheel 3, so that part of the fibers detached from the surface of the sample adhere to the surface of the test tape, and the other part enters the collection cavity 4 along the downward flowing airflow to be collected, avoiding the distribution of these scattered fiber debris in the test area 12, and reducing the workload of subsequent cleaning;

[0049] After the fiber debris is intercepted by the interception layer 42, the scattered fiber debris is concentrated and collected in the interception layer 42, so that only the weight change of the interception layer 42 needs to be determined to obtain the weight of the collected scattered fibers, and then the weight data is added to the weight of the adhered fibers measured on the test tape, so that the measured data is more consistent with the true fiber weight detached from the sample, effectively reducing the error and improving the measurement accuracy.

[0050] Embodiment four:

[0051] On the basis of embodiment three, the interception layer 42 has various possible embodiments that can separate and limit the collection of fiber debris in the airflow, which can be applied to the present application; the present embodiment provides a possible technical solution, specifically, the interception layer 42 includes an upper separation net 43 and a lower interception net 44, which are elastically connected with the inner wall of the collection cavity 4;

[0052] The gap region between the separation net 43 and the interception net 44 forms a collection area 45, which is filled with collection particles; the accumulated collection particles occupy two-thirds of the space of the collection area 45, so that a gap is maintained between the top region of the collection particles and the separation net 43; the surface of the collection particles is rough; the particle size of the collection particles is greater than the pore size of the interception net 44 and smaller than the pore size of the separation net 43, so that the collection particles are limited in the collection area 45; and the interception net 44 and the separation net 43 are both provided with a vibrator, which can be a miniature vibration motor.

[0053] Specific working process: on the basis of the specific working process in embodiment three, when the purification fan is started, the downward flowing purification airflow passes through the interception layer 42, and needs to penetrate the separation net 43, the gap of the collection particles in the collection area 45, and the lower interception net 44 in turn; in this process, the separation net 43 with a larger pore size can separate the fiber debris with a larger volume in the purification airflow, and the fiber debris with a smaller volume is intercepted when penetrating the gap of the collection particles, so that the separated fiber debris is dispersed into different regions according to the volume difference, avoiding the excessive concentration of fiber debris affecting the passability of the interception layer 42.

[0054] Further, the vibrator is started at a regular time to vibrate the interception net 44 and the separation net 43, so as to vibrate the collection particles in the collection area 45 between them; on the one hand, the vibration promotes the mutual flow and mixing of the collection particles, so that the fiber debris intercepted by the collection particles is more evenly dispersed into different regions, avoiding the concentration of fiber debris; and the rolling collection particles make the fiber be extruded, and in contact with the rough surface of the collection particles, and are compressed into a ball in the rolling process and the extrusion impact of the surrounding collection particles, reducing the volume of the collected fiber debris, thus reducing the obstruction to the downward penetrating airflow and ensuring that more fiber debris can be collected; on the other hand, the vibrating collection particles impact the separation net 43 upward, and part of the collection particles can pass through the filter holes of the separation net 43, playing a role in dredging and cleaning the filter holes of the separation net 43, ensuring the passability of the separation net 43, and also promoting the fiber debris on the separation net 43 to fall off the separation net 43 into the collection area 45 and mix evenly into the gap of the flowing collection particles to be collected, ensuring the smooth collection of the floating fiber debris.

[0055] Embodiment five:

[0056] On the basis of embodiment four, the edge parts of the separating net 43 and the intercepting net 44 are provided with fixing frames, which are convenient for installation and dismounting and can protect the edge ends, and the corresponding vibrator is arranged on the corresponding fixing frame; the horizontal bars 431 arranged transversely on the two sides of the fixing frame of the edge part of the separating net 43 are slidingly embedded into the positioning holes arranged correspondingly transversely on the inner wall of the collecting cavity 4, and the horizontal bars 431 and the inner walls of the corresponding positioning holes are connected through elastic members;

[0057] The longitudinal bars 441 arranged vertically on the lower surface of the fixing frame of the edge part of the intercepting net 44 are slidingly embedded into the positioning holes arranged correspondingly on the inner wall of the collecting cavity 4, and the longitudinal bars 441 and the positioning holes are connected through elastic members; the above-mentioned elastic members can be selected from springs; the collecting particles are of conductive metal material, have large density, and the impact on the separating net 43 is strengthened during the vibration process; the separating net 43 is of non-metal insulating material, the intercepting net 44 is of conductive metal material, and the contact parts of the inner wall of the collecting cavity 4 and the intercepting net 44 are of conductive metal material and grounded; in order to measure the weight change of the separating net 43 and the intercepting net 44, the weighing sensors can be arranged at the joint parts of the intercepting net 44 and the longitudinal bars 441 and the joint parts of the separating net 43 and the horizontal bars 431 respectively to detect the weight change in real time, or the weighing sensors can be dismounted after the test to be weighed on the weighing instrument to analyze and calculate the weight change;

[0058] Specific working process: on the basis of the specific working process in embodiment four, when the vibrator is started, the intercepting net 44 is limited through the cooperation of the longitudinal bars 441 and the vertically extending positioning holes, so that the intercepting net 44 keeps vertical vibration under the action of the vibrator, thereby promoting the vertical jumping of the collecting particles located on the upper side of the intercepting net 44, strengthening the vertical flow of the collecting particles and further promoting the vertical jumping of the collecting particles to impact and clean the limiting debris adhered to the separating net 43 on the upper side; and the vertical vibration of the intercepting net 44 makes the spacing between the separating net 43 and the intercepting net 44 change continuously, the change of the size of the collecting area 45 accelerates the air exchange between the inner and outer areas of the collecting area 45, and accelerates the separation of the limiting debris adhered to the separating net 43

[0059] Meanwhile, the upper separating net 43 is limited by the edge horizontal rod 431 and the corresponding positioning hole, so that the separating net 43 is horizontally vibrated under the action of the vibrator, the collected particles which contact and pass through the filter holes of the separating net 43 are impacted by the separating net 43, so that the collected particles slide horizontally along the surface of the separating net 43, the contact degree between the collected particles and the separating net 43 is improved, and the horizontal rolling of the collected particles also promotes the mutual entanglement between the collected particles and the fiber scraps adhered to the separating net 43, and the fiber scraps are passed through the filter holes of the separating net 43 under the action of the vibration, so that the fiber scraps adhered to the separating net 43 are fully cleaned and recycled into the gap between the collected particles, and the passability of the separating net 43 is ensured.

[0060] Further, the separating net 43 is made of non-metal insulating material, and the inner wall of the collecting cavity 4 connected to the separating net 43 is also made of non-metal insulating material, so that when the fiber scraps flowing downward contact and rub against the separating net 43, static electricity is accumulated on the separating net 43, and the fiber scraps are separated from the purified airflow due to the electrostatic adsorption and adhered to the separating net 43; when the vibrator is started to clean at a regular time, the collected particles in vibration contact the separating net 43, the static electricity on the separating net 43 is conducted out, the electrostatic adsorption is reduced, so that the fiber scraps adhered to the separating net 43 are more easily separated and carried away by the collected particles in vibration, mixed into the gap between the collected particles, compressed by impact, and limited in the collecting area 45, so that the test work is normally carried out.
