The present invention relates to yarns, in particular to an apparatus for processing yarns
With the increment of population, resources of earth are reduced gradually, while demands for resources are increased day by day. Generally, conversion of energy will cause heat dissipation so as to deteriorate greenhouse effect. Ozone layer of the earth is destroyed. As a result, the ultraviolet ray is greatly enhanced so that environment becomes worse and worse.
Light and heat hurt people's bodies. Over amount ultraviolet ray and overheat temperature hurt skin and people's bodies. Currently, people wear functional clothes for avoiding dangers from ultraviolet ray and high temperature. Moreover, current used washing agents are so strong so as to destroy the functions of clothes in washing machines after several times of washing, such as 5 to 10 times of washing.
For far infrared ray warming clothes used in winter, fibers are added with mineral powders and then are made as yarns. However, the shapes of the yarns are fixed and thus they are easily to be replaced by new kinds of yarns. As a result the old yarns are not used and then deserted.
Therefore the inventor of the present invention thought to add additives to the yarns directly, such as additives of temperatures and light sensitive are added to the yarn so that people wearing the clothes made of the yarns are protected by the yarns. Furthermore, the clothes producer can add functions to the yarns when orders are receipt.
Accordingly, object of the present invention is to provide an apparatus for processing yarns, wherein yarns processed from above procedures have the property of additives added thereon. When the yarns are made as clothes, in dying process, the properties of the additives including heat absorption, color change due to light or temperature variation will be presented so that these properties will present in the clothes made of the yarns so that people wearing the clothes will feel cool, or feel color change due to light or temperature variations.
To achieve above object, the present invention provides an apparatus for processing yarns, comprising: a first roller set for extending yarn bean; a node generator installed after the first roller set for forming node section of the yarn beam; a first cleaning chamber installed after the node generator for cleaning the yarn beams; a material chamber for adding additive to the yarn beam; a second roller set installed after the material chamber for extending the yarn beam; a first heating chamber installed after the second roller set for thermally setting additives to the yarn beam so that the additives are firmly secured to the yarn of the yarn beam; a third roller set installed after the heating chamber for controlling the heating time of the yarn beam in the first heating chamber; and a fourth roller set installed after the third roller set for winding the yarn beam to a desired shape.
With reference to
A roll of yarns 1 is a spindle winding by many circles of yarns. The spindle has a hollow center which serves to be received a shaft of a spindle frame. The yarns 1 are selected from one of polyester false twisting yarns, polyester nylons yarn, polyester nylon short fibers, polyester and cotton mixing yarns.
A first roller 2 serves to transfer the yarn 1 with a speed of 100-1000 meters per minute to proceed operation process.
A node generator 3 installed behind the first roller 2 for forming nodes 11 on the yarn 1 with an air nozzle 31 so that yarn fibers are compressed tightly in the node sections. High pressure air is sprayed into the nozzle to form turbulent flow for forming the nodes so that the yarn has uniform physical properties. This is beneficial to the following operation.
In forming nodes on the polyester or polyamide yarns, an air nozzle 31 causes the yarn to compress as a narrow beam and wind them together. There are 80 to 120 nodes per meters of the yarns.
A cleaning chamber 4 is installed after the node generator 3 for cleaning the yarn after forming the nodes with clean water for removing oils left on the yarn. The yarn may pass through or be sprayed by water for cleaning so that the original yarns are cleaned in the succeeding process.
A material adding chamber 5 stores additive materials 51 which will be added to the cleaned yarn 1. The additive material may be at least one of xylitol, spirooxazines dye, 6′-(diethylamino)-1′,3′-dimethyl_uoran (which is also called as spiro [isobenzofuran-1 (3H), 9′-[9H]xanthen]-3-one, 6′-(diethylamino)-1′, 3′-dimeth (CAS No. 21934-68-9) lactone dyes, (1-hexadecanol, CASNo. 36653-82-4) and melamine, CAS No. 108-78-1. If the additive 51 is formed by mixing xylitol and high molecular polymer. The size of ofxylitol powders is several millimeters. The additive is mixed powders of xylitol and high molecular polymer which are heat-absorbed, in that the xylitol has a ratio of 6 to 12 weight or volume percentages and the high molecular polymer has a ratio of 88 to 94 weight or volume percentages. The additives in the material adding chamber 5 has liquid form so that when the yarn 1 passes through the additives 51, the yarn 1 is enclosed by the additives 51.
The additive is mixed powders of spirooxazines dye and high molecular polymer which are color changed due to light radiation, in that the spirooxazines dye has a ratio of 6 to 12 weight or volume percentages and the high molecular polymer has a ratio of 88 to 94 weight or volume percentages.
Or the additive contains high molecular polymer and at least one of 6′-(diethylamino)-1′,3′-dimethyl_uoran (also called as spiro[isobenzofuran-1(3H), 9′-[9H]xanthen]-3-one, 6′-(diethylamino)-1′, 3′-dimeth (CAS No. 21934-68-9) lactonic dyes, 1-hexadecanol, CASNo. 36653-82-4 and melamine (CAS No. 108-78-1) which are color changed due to temperature variation, in that the color changed material has a ratio of 6 to 12 weight or volume percentages and the high molecular polymer has a ratio of 88 to 94 weight or volume percentages.
A second roller set 6 is installed after the material chamber 5 for extending the yarn beam 1 passing through the node generator 3, the cleaning chamber 4 and the material chamber. The second roller 6 could extend the yean beam with a speed of 100 meter to 1000 meter per minutes to that the yarn beam 6 is extended extremely.
A heating chamber is installed after the second roller for fixing the additive material 51 to each fiber of the yarns firmly. The temperature of the heating chamber 7 is between 100 to 600 degree C.
A third roller 8 is installed after the heating chamber 7. The yarn passes through the heating chamber 7 will be heated. The rotation of the third roller 8 causes the yarn passing therethrough with a speed of 100 to 1000 meters per minutes. Furthermore, the yarn 1 passed through the heating chamber 7 is warmed under temperature of 100 to 600 degree C.
A fourth roller 9 is installed after the third roller 8 for shaping the yarns are wound to have desire shapes with an processing speed of 100 to 1000 meters.
As illustrated in
Yarns processed from above procedures have the property of additives added thereon. When the yarns are made as clothes, in dying process, the properties of the additives including heat absorption, color change due to light or temperature variation will be presented so that these properties will present in the clothes made of the yarns so that people wearing the clothes will feel cool, or feel color change due to light or temperature variations.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
