Nowadays, the hook and loop tape commonly used in life is cheap and has a terrific effect. Because of these factors, the worth and quality of the hook and loop tape have become essentially the most involved issue. For some industries that use hook and loop tape, because the quantity of hook and loop tape bought each time is comparatively massive, the superb hook and loop tape can’t only successfully improve their production efficiency, but also reduce lots of costs of enterprises due to its longer service life. What factors will have an effect on the quality of hook and loop tape?
Raw materials for making hook and loop tape. Hook and loop tape is made up of certain types of yarns, and completely different yarns are made up of different fibers.
Fiber is a kind of fabric with very fine diameter, often a number of microns to tens of microns, and its length is many instances bigger than that of fineness, and has certain flexibility. There are a lot 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 can 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 within the process of hook and loop tape processing, or within the process of stitching and wearing, they should bear a wide range of exterior forces, similar to stretching, torsion, bending, friction and repeated external forces, so that the hook and loop tape will produce corresponding deformation.
(2) With certain fineness and length, the fineness and length of fiber ought to meet the necessities of hook and loop tape processing technology. In the production process of hook and loop tape, the fibers often must 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 can help to soak up sweat and grease of human body, and make the material will be dyed and printed. Air permeability makes clothing comfortable and cool.
(4) Chemical stability: the hook and loop tape fiber must have certain chemical stability for light, heat, acid and alkali solutions. Only in this way can the service lifetime of the fiber not be reduced and damaged under the action of the above substances.
(5) On the whole, hook and loop tape have to be dyed and dyed with varied colors or patterns to achieve its remaining purpose. Therefore, the hook and loop tape fiber should have certain dyeing properties.
