Nowadays, the hook and loop tape commonly utilized in life is affordable and has a great effect. Because of those factors, the worth and quality of the hook and loop tape have grow to be essentially the most concerned 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 superb hook and loop tape cannot only effectively improve their production effectivity, but also reduce a number of prices of enterprises as a result of its longer service life. What factors will have an effect on the quality of hook and loop tape?
Raw materials for making hook and loop tape. Hook and loop tape is made up of sure types of yarns, and completely different yarns are made up of different fibers.
Fiber is a kind of fabric with very fine diameter, usually a number of microns to tens of microns, and its size is many occasions larger than that of fineness, and has certain flexibility. There are various kinds of fibers in nature, but 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 following properties:
(1) Good physical and mechanical properties, hook and loop tape fiber should be processed before it can be utilized for weaving. Whether in the process of hook and loop tape processing, or in the process of sewing and wearing, they have to bear quite a lot of exterior forces, corresponding 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 size, the fineness and length of fiber ought to meet the requirements of hook and loop tape processing technology. In the production process of hook and loop tape, the fibers usually 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 soak up sweat and grease of human body, and make the material can 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 lifetime of the fiber not be reduced and damaged under the action of the above substances.
(5) Normally, hook and loop tape must be dyed and dyed with numerous colors or patterns to achieve its closing purpose. Due to this fact, the hook and loop tape fiber ought to have sure dyeing properties.
