Description
Technical field
The present invention relates to the plastic heddle field, the heald that is specifically related to a kind of padding is with polyester film and preparation method thereof.
Background technology
Heald is the easy-consuming fitting of loom, and the center has aperture (harness eye) to supply warp thread therefrom to pass.Warp thread of every heald control drives warp thread and moves up and down to form shed open, is convenient to introduce weft yarn.
Heald was made with stainless steel in the past, began to occur plastic heddle Chinese market in 2003, thought that at that time plastic heddle finally can substitute the stainless steel heald, but until today two kinds of healds use is all arranged, the phenomenon that plastic heddle substitutes the stainless steel heald does not also appear.The advantage of stainless steel heald is a smooth surface, wear-resisting lastingly, its shortcoming be weight big, get rusty easily, big to the loss of machine, power consumption is big.By contrast, plastic heddle is in light weight, little to the loss of machine, can not get rusty, clean easily, but its wearability, hardness and service efficiency are all not as the stainless steel heald.
Along with the development of plastics synthetic material and process technology, adopting plastic heddle progressively to substitute the stainless steel heald is a kind of development trend.Heald is the water-jet loom easy-consuming fitting, and its technical performance index is directly determining the quality of cloth, and plastic heddle need solve is the problem of the aspect such as wearability and hardness of material.The wearability of heald improves, and just can weave the spinning of kinds such as heavy twist and even delustring, also just might reduce the thickness of heald simultaneously, and many dress heads part make the warp thread radical that can weave more, thereby make plastic heddle can weave the spinning of more kinds; In addition, improve the service life that wearability can also prolong plastic heddle, the problem of hardness also only finds way to solve on the basis that wearability improves simultaneously.
In actual use, people not only require plastic heddle that higher wearability and hardness are arranged, but also require the surface to possess various colors.At first, plastic heddle must be nontransparent as the stainless steel heald.Because spinning threadling is very thin, and harness eye is very little, if heald is transparent, then be unfavorable for wearing silk, particularly under high-speed case, leak silk easily.Secondly; The color of plastic heddle preferably can come with the colouring discrimination of yarn; General yarn majority is black or white; Heald black or other color beyond the white sometimes also arranged, so except the grey with similar stainless steel heald, also should have other color (like blueness or green etc.).At last, because the number of yarn and heald is various, and repetitive operation speed is fast, thus require the color of heald can not be too dazzling, in order to avoid cause visual fatigue.The color of general recommendations plastic heddle is soft relatively light gray, light blue or light green color.
Application number is 201010225455.5 (publication No.: CN 101942727; Date of publication: one Chinese patent application on January 12nd, 2011) also proposes a kind of polyester film heald and preparation method thereof; Use in three-layer co-extruded structure, half delustring polyester slice (content is different in the different layers) and each layer and add an amount of color masterbatch; The plastic heddle of gained has different colours, and the comprehensive mechanical intensity and the anti-wear performance of material all increase.
In plastics section raw material, adding color masterbatch is that preparation has the used method of plastic heddle of different colours at present, and the advantage of this method is directly simple, but shortcoming is also arranged.Adopt color masterbatch like this method, make color be inconvenient to allocate, all will change the synthetic overall prescription of material even do the fine setting of some color aspects.In addition, color masterbatch plastic basis material inevitable and plastic heddle is mixed, can have influence on wearability and hardness or other performance of heald.And the interpolation of color masterbatch can have a strong impact on existing production system, and present most production of polyester lines all are to be used to produce clarity films, and the cleanliness factor in workshop is had relatively high expectations, and does not allow the introducing of color masterbatch and pollutes.Therefore, the production of coloured kind polyester heald film has received very big restriction.
