Nowadays, the hook and loop tape commonly used in life is cheap and has a terrific effect. Because of those factors, the price and quality of the hook and loop tape have turn out to be the most involved issue. For some industries that use hook and loop tape, because the quantity of hook and loop tape purchased each time is comparatively giant, the wonderful hook and loop tape cannot only successfully improve their production effectivity, but additionally reduce a whole lot of prices of enterprises as a consequence of its longer service life. What factors will affect 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 different yarns are made up of different fibers.
Fiber is a kind of material 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 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 can 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 should be processed earlier than it can be used for weaving. Whether within the process of hook and loop tape processing, or within the process of sewing and wearing, they have to bear quite a lot of external forces, similar to stretching, torsion, bending, friction and repeated exterior forces, in order 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 necessities of hook and loop tape processing technology. Within the production process of hook and loop tape, the fibers normally must be twisted collectively 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 can be dyed and printed. Air permeability makes clothing comfortable and cool.
(4) Chemical stability: the hook and loop tape fiber will need to 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 action of the above substances.
(5) On the whole, hook and loop tape must be dyed and dyed with varied colors or patterns to achieve its ultimate purpose. Therefore, the hook and loop tape fiber ought to have certain dyeing properties.
