Nowadays, the hook and loop tape commonly used in life is reasonable and has an incredible effect. Because of these factors, the price and quality of the hook and loop tape have develop into 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 relatively giant, the wonderful hook and loop tape can not only successfully improve their production effectivity, but additionally reduce quite a lot of prices of enterprises attributable to 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 sure types of yarns, and totally different yarns are made up of various fibers.
Fiber is a kind of material with very fine diameter, usually a number of microns to tens of microns, and its length is many instances bigger than that of fineness, and has certain flexibility. There are numerous kinds of fibers in nature, however not all fibers can be used for spinning and weaving. Only the fiber that can be utilized 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 utilized for weaving. Whether in the process of hook and loop tape processing, or within the process of stitching and wearing, they must bear quite a lot of exterior forces, such as 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 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 usually need to be twisted collectively before 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 soak up sweat and grease of human body, and make the material might be dyed and printed. Air permeability makes clothing comfortable and cool.
(four) 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 action of the above substances.
(5) Usually, hook and loop tape should be dyed and dyed with numerous colors or patterns to achieve its closing purpose. Therefore, the hook and loop tape fiber ought to have certain dyeing properties.
