According to what has been disclosed in Taiwan Pat. No. M263013, a hairiness treatment is used to form fibriform hooks of the fastening fabric, so the fibriform hooks are not provided with a uniform directivity, thereby causing a poor adhering and fastening effect when the fibriform hooks are engaged with fibriform loops. Referring to

The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:
Referring to
The texturing and fabricating means for the restraining fabric structure 1 are disclosed as follows:
The fastening fabric further comprises a loop fabric structure 2, the fibriform loop fabric structure 2 comprises a second base structure 21 and a plurality of fibriform loop bundles 22 protruding from a surface of the second base structure 21, and each of the loop bundles 22 comprises a plurality of fibriform loops 221. As such, when the restraining fabric structure 1 and the loop fabric structure 2 are in contact for being mutually adhered, the inclined restraining fibers 121 and the fibriform loops 221 are tangled with each other, so that a soft material, such as a fabric, is provided with an adhering and fastening effect.
As such, in practical implementations, the size of the fibriform loops 221 are smaller than 5 deniers, when the denier of a fibriform loop 221 is smaller than 0.5, the loop fabric structure 2 is able to be fabricated by utilizing composite fibers and using a fiber splitting treatment, after the composite fibers are split by a conventional chemical or mechanical method forming micro-fibers, micro-fibers having more amount of fibers than the original composite fibers and having finer size than the original composite fibers are fabricated. And a height (L2) defined by the loop bundles 22 protruding from the surface of the second base structure 21 is from 0.2 mm to 4 mm.
Wherein, in practical implementations, thermal shrinkable fibers can be added in the loop fabric structure 2, so the high temperatures generated during a dyeing treatment is able to allow the thermal shrinkable fibers to shrink, thereby enabling the fibriform loops 221 which are not shrinkable to be in a more loosened status.
The composite fibers can be sea-island composite fibers or segment-pie composite fibers; the fiber splitting treatment for the former one includes a weight reduction treatment for dissolving and removing the sea portions and only saving the island portions, so as to provide microfibers, and the fiber splitting treatment for the later one can be a mechanical fiber splitting treatment or a reduction fiber splitting treatment, so as to provide microfibers.
As such, the fiber splitting treatment is performed on the loop bundles 22 on the surface of the second base structure so as to fabricate the micro-fibriform loops 221, and the micro-fibriform loops 221 and the inclined restraining fibers 121 are able to provide an enhanced adhering and fastening function.
The size of the micro-fibriform loop 221 and the size of the inclined restraining fiber 121 are properly chosen for achieving an effect of easily tangling with each other; for example, polyester filament yarns of 150D (denier)/48f (fiber count) are adopted as the restraining fibers 121, microfibers of 80D/72*12f are adopted as the micro-fibriform loops 221; the size of the restraining fiber 121 is 3.125D/f, and the size of the micro-fibriform loop 221 is 0.093D/f. If the size of 1D/f is adopted as the size of the fibriform loop 221 so that the strength of each single fiber of the fibriform loop 221 can be increased, the size of the restraining fiber 121 is preferably greater than 6D/f.
In addition, the restraining fabric structure 1 of the fastening fabric and the loop fabric structure 2 of the fastening fabric can be fabricated by a circular knitted or warp knitted or woven fabric having double-face loop structure, so the inclined fiber bundles 12 and the loop bundles 22 are respectively fabricated on different surfaces of the fabric, and after the plural loops of the restraining fabric structure 1 are processed with the shearing treatment and the thermal pressing and forming treatment, the plural inclined fiber bundles 12 of the restraining fabric structure 1 are fabricated on one surface of the fabric and the plural loop bundles 22 of the loop fabric structure 2 are fabricated on the other surface of the fabric.
Referring to
The planar loop fabric structure 3 can be fabricated by a circular knitted or warp knitted or woven fabric having single-face loop-pile structure, so the restraining fabric structure 1 and the planar loop fabric structure 3 are respectively fabricated on different surfaces of the fabric, and the restraining fabric structure 1 is fabricated through performing the shearing treatment and the thermal pressing and forming treatment. When the fastening fabric is fabricated by the single-face loop-pile structure, during the shearing treatment, the length of the fiber of the restraining fabric structure 1 on one surface of the fabric can be set to a shorter length, and with the planar fibriform loops 321 of the planar loop fabric structure 3 on another surface of the fabric, the fabric is provided with features of thin and soft, which is suitably to be used as a fabric for wrapping.
As shown in
As mentioned above, the reasons why the restraining fibers erectly and loosely fabricated on a conventional fastening fabric having a poor vertical adhering and fastening effect has been clearly explained, however in practical applications, not only the vertical adhering and fastening effect of the fastening fabric should be concerned, the horizontal adhering and fastening effect shall also be put into considerations, so that the actual requirements thereof can be satisfied.
As shown in
As such, the normal component and the parallel component of the action force (external pulling force) are determined according to the inclined angle θ, when the inclined angle is greater than 60 degrees, the adhering and fastening effect provided in both the vertical direction and the horizontal direction is not effectively increased; when the inclined angle is 45 degrees, the adhering and fastening effect provided in both the vertical direction and the horizontal direction is effectively increased; when the inclined angle is smaller than 5 degrees, the adhering and fastening effect provided in both the vertical direction and the horizontal direction is significantly increased, but the restraining fibers 121 in an overly inclined status would be less easily tangled with the fibriform loops 221. Accordingly, the inclined angle defined between the restraining fibers 121 and the first base structure 11 is preferably to be greater than 5 degrees but smaller than 60 degrees, and more preferably to be greater than 15 degrees but smaller than 50 degrees.
Moreover, the inclined fiber bundles 12 of the restraining fabric structure 1 are fabricated by using a shearing treatment and going through a process for a proper time in an environment with proper pressures and temperatures, the condition of the process is as follows: the temperature is between 140 to 250 Celsius degree, and under a proper pressure, a thermal pressing and forming treatment is performed for 10 to 60 seconds, so the inclined restraining fibers 121 are provided with a rigidity after the thermal pressing and forming treatment, meanwhile the thermal pressing and forming treatment also enables the structural body formed through weaving the restraining fabric structure 1 and the first base structure 11 to be more firmly, so the inclined fiber bundles 12 are enabled to stably erect, and the adhering and fastening effect of the fastening fabric can be further enhanced.
Furthermore, the fiber length of the inclined fiber bundles 12 of the restraining fabric structure 1 protruding from the surface of the first base structure 11 would affect the whole thickness of the restraining fabric structure 1, and the resultant torque of the action force is also affected, so the length (L1) of the restraining fiber 121 is preferably from 0.2 mm to 5 mm, and more preferably from 0.4 mm to 3 mm.
Furthermore, the condition and the required equipment for the thermal pressing and forming treatment of the restraining fabric structure 1 is similar to the process method of a sublimation paper printing, so, if the sublimation paper printing is adopted for fabricating the restraining fabric structure 1 of the fastening fabric, the thermal pressing and forming treatment can be omitted.
According to the present invention, the texturing means of the fastening fabric is circular knitting, warp knitting or weaving a fabric, if elastic fibers are added in the first base structure 11 and the second base structure 21, such as the elastic fibers under the trademark of Lycra, the elasticity of the fastening fabric can be increased and the fastening fabric can be suitably applied in wrapping or bonding a protection equipment.
