Nowadays, the hook and loop tape commonly utilized in life is reasonable and has a fantastic effect. Because of these 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 bought each time is relatively large, the excellent hook and loop tape cannot only effectively improve their production efficiency, but additionally reduce a variety of costs of enterprises as a consequence 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, usually a number of microns to tens of microns, and its length is many occasions 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 may 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 should be processed before it can be used for weaving. Whether or not in the process of hook and loop tape processing, or in the process of stitching and wearing, they should bear a wide range of external forces, similar to stretching, torsion, bending, friction and repeated external 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. In the production process of hook and loop tape, the fibers usually need to be twisted collectively earlier than 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 may also help to absorb sweat and grease of human body, and make the fabric can be dyed and printed. Air permeability makes clothing comfortable and cool.
(4) Chemical stability: the hook and loop tape fiber must 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 motion of the above substances.
(5) Generally, hook and loop tape must be dyed and dyed with various colours or patterns to achieve its ultimate purpose. Therefore, the hook and loop tape fiber ought to have sure dyeing properties.
