Nowadays, the hook and loop tape commonly used in life is affordable and has a great effect. Because of those factors, the worth and quality of the hook and loop tape have become probably the most involved issue. For some industries that use hook and loop tape, because the quantity of hook and loop tape purchased every time is comparatively large, the excellent hook and loop tape can not only effectively improve their production effectivity, but additionally reduce numerous costs of enterprises on account of 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 various fibers.
Fiber is a kind of fabric with very fine diameter, normally a number of microns to tens of microns, and its length is many instances larger than that of fineness, and has sure flexibility. There are lots of kinds of fibers in nature, however not all fibers can be utilized for spinning and weaving. Only the fiber that can be used to produce hook and loop tape could be called hook and loop tape fiber.
As a hook and loop tape fiber, it ought to have the following properties:
(1) Good physical and mechanical properties, hook and loop tape fiber must be processed before it can be used for weaving. Whether or not within the process of hook and loop tape processing, or in the process of sewing and wearing, they must bear quite a lot of external forces, reminiscent of stretching, torsion, bending, friction and repeated exterior forces, so that the hook and loop tape will produce corresponding deformation.
(2) With sure fineness and length, the fineness and size of fiber ought to meet the requirements of hook and loop tape processing technology. In the production process of hook and loop tape, the fibers often need to be twisted together before they are often 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 sure 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 motion of the above substances.
(5) On the whole, hook and loop tape have to be dyed and dyed with various colors or patterns to achieve its ultimate purpose. Due to this fact, the hook and loop tape fiber should have certain dyeing properties.
