Nowadays, the hook and loop tape commonly utilized in life is reasonable and has an excellent effect. Because of those factors, the value and quality of the hook and loop tape have turn out to be probably the most concerned issue. For some industries that use hook and loop tape, because the quantity of hook and loop tape bought every time is comparatively large, the excellent hook and loop tape can not only effectively improve their production efficiency, but additionally reduce loads of costs of enterprises as a result of its longer service life. What factors will affect the quality of hook and loop tape?
Raw supplies for making hook and loop tape. Hook and loop tape is made up of sure types of yarns, and totally different yarns are made up of various fibers.
Fiber is a kind of fabric with very fine diameter, usually several microns to tens of microns, and its length is many instances bigger than that of fineness, and has certain flexibility. There are lots of kinds of fibers in nature, but not all fibers can be used for spinning and weaving. Only the fiber that can be utilized to produce hook and loop tape will be called hook and loop tape fiber.
As a hook and loop tape fiber, it should have the next properties:
(1) Good physical and mechanical properties, hook and loop tape fiber must be processed before it can be utilized for weaving. Whether or not in the process of hook and loop tape processing, or in the process of stitching and wearing, they need to bear quite a lot of external forces, equivalent to stretching, torsion, bending, friction and repeated exterior forces, so that the hook and loop tape will produce corresponding deformation.
(2) With certain fineness and size, the fineness and size of fiber should meet the requirements of hook and loop tape processing technology. Within the production process of hook and loop tape, the fibers often have to be twisted collectively before they can be spun into yarn.
(three) Hygroscopicity and air permeability, moisture absorption and air permeability are the essential sanitary properties of hook and loop tape fiber. Good hygroscopicity may also help to absorb sweat and grease of human body, and make the material might be dyed and printed. Air permeability makes clothing comfortable and cool.
(four) Chemical stability: the hook and loop tape fiber should have sure chemical stability for light, heat, acid and alkali solutions. Only in this way can the service life of the fiber not be reduced and damaged under the motion of the above substances.
(5) Typically, hook and loop tape should be dyed and dyed with various colours or patterns to achieve its ultimate purpose. Subsequently, the hook and loop tape fiber should have sure dyeing properties.
