Nowadays, the hook and loop tape commonly used in life is reasonable and has an ideal effect. Because of those factors, the value and quality of the hook and loop tape have change into probably 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 relatively large, the superb hook and loop tape can’t only effectively improve their production effectivity, but in addition reduce loads of prices of enterprises on account 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 different yarns are made up of different fibers.
Fiber is a kind of material with very fine diameter, often several microns to tens of microns, and its size is many occasions larger than that of fineness, and has sure flexibility. There are many kinds of fibers in nature, however not all fibers can be utilized for spinning and weaving. Only the fiber that can be utilized 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 next properties:
(1) Good physical and mechanical properties, hook and loop tape fiber have to be processed before it can be utilized for weaving. Whether within the process of hook and loop tape processing, or within the process of sewing and wearing, they should bear a variety of exterior forces, reminiscent of stretching, torsion, bending, friction and repeated exterior forces, in order that the hook and loop tape will produce corresponding deformation.
(2) With certain fineness and size, 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 often have to be twisted together earlier than they can be 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 will help to absorb sweat and grease of human body, and make the fabric might be dyed and printed. Air permeability makes clothing comfortable and cool.
(four) Chemical stability: the hook and loop tape fiber should 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 action of the above substances.
(5) Normally, hook and loop tape should be dyed and dyed with numerous colors or patterns to achieve its last purpose. Due to this fact, the hook and loop tape fiber should have sure dyeing properties.
