Nowadays, the hook and loop tape commonly utilized in life is affordable and has a terrific effect. Because of these factors, the worth and quality of the hook and loop tape have develop into essentially 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 relatively massive, the superb hook and loop tape can’t only successfully improve their production effectivity, but in addition reduce a number of prices of enterprises on account of its longer service life. What factors will have an effect on the quality of hook and loop tape?
Raw supplies 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 several microns to tens of microns, and its length is many instances larger than that of fineness, and has sure flexibility. There are various kinds of fibers in nature, but not all fibers can be used for spinning and weaving. Only the fiber that can be used to produce hook and loop tape will 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 have to be processed earlier than it can be used for weaving. Whether in the process of hook and loop tape processing, or within the process of sewing and wearing, they should bear quite a lot of exterior forces, comparable to stretching, torsion, bending, friction and repeated external forces, so that the hook and loop tape will produce corresponding deformation.
(2) With sure fineness and length, the fineness and length of fiber should meet the necessities of hook and loop tape processing technology. In the production process of hook and loop tape, the fibers often have to 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 might help to soak up sweat and grease of human body, and make the fabric could 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 various colors or patterns to achieve its closing purpose. Due to this fact, the hook and loop tape fiber ought to have certain dyeing properties.
