Nowadays, the hook and loop tape commonly used in life is affordable and has a great effect. Because of those factors, the price and quality of the hook and loop tape have change into the most involved issue. For some industries that use hook and loop tape, because the quantity of hook and loop tape bought every time is relatively large, the excellent hook and loop tape can not only successfully improve their production efficiency, but additionally reduce a variety 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 certain types of yarns, and totally different yarns are made up of different fibers.
Fiber is a kind of fabric with very fine diameter, normally several microns to tens of microns, and its size is many instances larger than that of fineness, and has certain flexibility. There are a lot of kinds of fibers in nature, but 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 should have the next 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 within the process of hook and loop tape processing, or within the process of stitching and wearing, they have to bear a wide range of exterior forces, such as 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 requirements of hook and loop tape processing technology. Within the production process of hook and loop tape, the fibers normally should be twisted together earlier than they are often spun into yarn.
(3) 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 soak up sweat and grease of human body, and make the material could be dyed and printed. Air permeability makes clothing comfortable and cool.
(four) Chemical stability: the hook and loop tape fiber will need to have certain 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) Basically, hook and loop tape must be dyed and dyed with varied colours or patterns to achieve its closing purpose. Due to this fact, the hook and loop tape fiber ought to have sure dyeing properties.
