Problems solved by technology

[0003] There are deficiencies in existing three-dimensional carpets: 1. The cut flower carpet with three-dimensional effect, the three-dimensional cut flower is limited in output and quality, because it is artificial cut flower, labor intensity is big, so the output is not high, and the cut flower The price of flowers is also very high, and everyone's cutting level is different, so the cutting effect is divided into good and bad, the batch consistency is limited, and there is a V-shaped angle, which is different from the three-dimensional carpet with high and low cuts. different
2. It is rare to use acrylic high-yield yarn. The main disadvantage is that acrylic requires color-spun shrinkage yarn. The one-time quantity is large, more than 20 tons, and it needs to be imported. It is difficult to find a yarn supplier, which is required by carpets. There are many colors, and it is more difficult to buy colored spun acrylic

Embodiment 1

[0049] 1) Use 100 kilograms of 300D / 72F PBT monofilament to twist and weave into PBT yarn, the twist is 250 twists / m, and the twist direction is "Z" twist direction. During the doubling process, add 0.5 % of mineral oil;

[0050] 2) Plying and twisting again, the PBT yarn obtained in the above steps is twisted again, 300D / 2 ply yarn is plyed and twisted, the twist is 180 twists / m, and the twist direction is set as "S" twist direction. The technical requirements for twisting are relatively high, and the twist deviation must be controlled within 2%;

[0051] 3) Yarn dyeing and setting: Dyeing determines the color according to the carpet pattern, and the heat setting requirements of the yarn are very high. The heat setting method is carried out in a hot oven. The temperature of the oven is controlled at 70°C, the oven time is 40 minutes, and the shrinkage rate reaches 28%. ;

[0052] 4) Carpet weaving operation: Wilton machine is selected for weaving thin blankets. Mix 300D / 2 ...

Embodiment 2

[0056] 1) Use 100 kilograms of 300D / 72F PBT monofilament to twist and weave into PBT yarn. The twist is 270 twists / m, and the twist direction is "Z" twist direction. During the doubling process, 1 % of mineral oil;

[0057] 2) Plying and twisting again, the PBT yarn obtained in the above steps is twisted again, 300D / 2 ply yarn is plyed and twisted, the twist is 190 twists / m, and the twist direction is set as "S" twist direction. The technical requirements for twisting are relatively high, and the twist deviation must be controlled within 3%;

[0058] 3) Yarn setting: The heat setting requirements of yarn are very high, and heat setting is carried out by using a hot oven method. The temperature of the oven is controlled at 90°C, the oven time is 30 minutes, and the shrinkage rate reaches 21%;

[0059] 4) Carpet weaving operation: Wilton machine is selected for weaving thin blankets. Mix 300D / 2 strands of PBT yarn and polypropylene yarn with 800 dtex / 150F single twist yarn, co...

[0064] 2) Plying and twisting again, the PBT yarn obtained in the above steps is twisted again, 300D / 2 ply yarn is plyed and twisted, the twist is 175 twists / m, and the twist direction is set as "S" twist direction. The technical requirements for twisting are relatively high, and the twist deviation must be controlled within 3%;

[0065] 3) Yarn setting: The heat setting requirements of yarn are very high, and heat setting is carried out by using a hot oven method. The temperature of the oven is controlled at 80°C, the oven time is 35 minutes, and the shrinkage rate reaches 30%;

[0066] 4) Weaving operation: Wilton machine is selected for thin blanket weaving. Mix 300D / 2 strands of PBT yarn and polypropylene yarn with 800 dtex / 150F single twist yarn, control the warp and weft density to 512 warp x 420 weft;...

Abstract

The invention relates to a method of weaving multi-layer carpet with polybutylece terephthalate (PBT) filaments. The method comprises the following steps: (1) entwisting a single PBT filament to a PBT yarn with degree of twist of 250 to 270 twists per meter; (2) combining the twisted PBT yarns into a double-thread yarn, and the degree of twist is 175 to 196 twists per meter; (3) processing the PBT yarn by dying and heat shaping; (4) weaving the PBT yarn which is processed by the step (3) and a yarn without contractility on a Wilton carpet machine to get the multi-layer carpet. The multi-layer carpet is good in third dimension effect, artificial flower-cutting is not necessary during the preparation process, the problems that the quality is not stable and mass production cannot be achieved are avoided due to the artificial flower-cutting, and the cost is reduced. The method is simple, the materials used are easy to buy, and the method can be popularized and used in a wide range.

Description

technical field [0001] The invention relates to a method for weaving carpets, in particular to a method for weaving multi-layered carpets with PBT filaments. Background technique [0002] There are very few high and low cut Wilton rugs on the market today. With the rapid development of the world economy and the continuous improvement of people's living standards, there is an increasingly personalized demand for carpet products. It turns out that carpets are generally flat, but the materials and patterns vary greatly, and there is no three-dimensional effect of high and low levels. However, the newly emerging three-dimensional carpets are favored by the market. The existing three-dimensional carpets mainly include the following types: 1. Cut flower carpets with a three-dimensional effect, and 2. Three-dimensional carpets obtained by using acrylic high-yield yarns. [0003] There are deficiencies in existing three-dimensional carpets: 1. The cut flower carpet with three-dime...
