(7) A first roller 2 serves to transfer the yarn 1 with a speed of 100-1000 meters per minute to proceed operation process.

(8) 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.

(9) In forming nodes on the polyurethane (PU) or 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.

(10) 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.

(11) 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, CAS No. 36653-82-4) and melamine, CAS No. 108-78-1. If the additive 51 is formed by mixing xylitol and high molecular polymer (acrylic or polyurethane (PU) or polyester), the size of xylitol 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.

(16) 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.

(18) As illustrated in FIG. 4, when the yarns of the raw material 1 are polyester material yarns (POYpartially oriented yarn or FDYfully drawn yarn) or nylon material yarns (POY or NFDYnon-fully drawn yarn), a second heating chamber W is added after the first roller 2. The temperature of the second heating chamber W is between 100 degree C. to 600 degree C. Then a cooling plate X is installed after the heating chamber W for causing the yarns are heat-shaped in false twisting state. The cooling plate X between the output of the front heating chamber W and the false twisting device Y is has a length of 0.5 to 1.5 meters. After the yarns are released from the false twisting state, the temperature is below 100 C. so that the shaping operation can be performed conveniently. A false twisting device Y is installed after the cooling plate X and an extension rollers Z is installed after the false twisting device Y for extension of the yarns passing through so that the polyester material yarns and nylon material yarns may become processed yarns.
