Problems solved by technology

Worsted yarn can be fluffy and soft after being mixed with different raw materials. Because of the hand feeling, the twist of worsted yarn is generally relatively low, and the twist coefficient is between 2.0 and 2.5. The smaller the twist, the stronger the strength. Small, so it is necessary to add a winding project after the worsted spinning project to remove the weak part in the middle of the yarn. The additional winding project means an increase in cost and labor; in addition, in the winding project, the automatic Air-twist knotting is also very risky. If the knot is small, the strength will not be enough. If the knot is large, there will be problems with the fabric surface. Therefore, the biggest disadvantage of worsted yarn lies in the problem of strength and labor.
[0004] Chinese patent CN03262303.8 discloses a cashmere bag yarn, which is specifically woven into a hollow bag structure by worsted cashmere yarn. , wear resistance, strength and other issues, but we all know that cashmere is very expensive, and if all cashmere is used, the strength will also be affected to a certain extent

Embodiment 1

[0015] Put 40D-34f-nylon FDY and wool tops with an average length of 76mm of 65% wool, 20% alpaca wool, and 15% nylon staple fiber, and place them on the hanging spindle above the fancy twister machine. Nylon FDY is fed along the 1# route, and is first woven into a hollow bag shape of 400D (1 / 22.6Nm) as the main body of the yarn; The nozzle blows the drawn top fiber into the hollow bag to form the hair-spraying hollow bag yarn of the present invention. Among them, the weight of the top before drawing is 0.964g±0.01g / 1m, the drawing ratio of the top is 25 times, and the air pressure of the nozzle is 0.3Mpa.

[0016] The strength of the obtained hair-sprayed bag yarn is 450cN, the total count is 1 / 12Nm, and there is no knot inside the yarn.

Embodiment 2

[0018] Put 50D-36f-polyester FDY and tops made of 30% wool, 10% alpaca, 45% acrylic staple fiber, and 15% nylon staple fiber with an average length of 92mm, and place them on the fancy twisting machine at the same time On the hanging spindle above, polyester FDY is fed along the 1# route, and is first woven into a 500D (1 / 18Nm) hollow bag shape as the main body of the yarn, and the top is fed along the 2# route, and is drawn to 0.044g / m by three roller After thickening, the drafted top fiber is blown into the hollow bag by the nozzle to form the hair-spraying hollow bag yarn of the present invention. Among them, the weight of the top before drawing is 1.01±0.01g / 1m, the drawing ratio of the top is 23 times, and the air pressure of the nozzle is 0.33Mpa.

[0019] The strength of the obtained hair-sprayed bag yarn is 600cN, the total count is 1 / 10Nm, and there is no knot inside the yarn.

Embodiment 3

[0021] First, 40D-34f-nylon FDY and 80S acrylic 100% spun yarn are processed by doubling machine, in which the twist coefficient of 80S acrylic 100% spun yarn is 3.6, and the doubling speed is 150m / min, and then the doubling The twisted yarn is twisted, the twist direction is S twist, the twist is 450T / M, and the number of revolutions of the twisting machine is 12000rmp to form a long and short composite yarn; 50% polyester staple fiber, 25% polyester staple fiber, and 25% alpaca hair are placed on the hanging spindle above the fancy twisting machine table at the same time. The composite yarn is fed along the 1# route and is woven into 1000D ( The hollow bag shape of 1 / 9Nm) is used as the main body of the yarn, and the wool top is fed along the 2# route, and after being drawn by three rollers to a thickness of 0.08g / m, the drafted wool top fiber is blown into the hollow bag by the nozzle to form the yarn. Invented hair spray hollow bag yarn. Among them, the weight of the w...

Abstract

The invention discloses a wool-blown hollow bag yarn. The main body of the yarn is a filament yarn made of terylene or nylon, or a composite yarn formed by the filament yarn and a staple fiber yarn made of other raw materials; wool refers to at least one of sheep wool, paco wool, acrylic staple fiber, polyester staple fiber and nylon staple fiber. The yarn has fluffy and soft handfeel, and is 20-30 percent higher than a worsted yarn of the same count in strength; a fabric made of the wool-blown hollow bag yarns is 8-20 percent lighter than a fabric of the same thickness made of the worsted yarns of the same count, and is better in heat-insulating effect.

Description

technical field [0001] The patent of the present invention relates to a new type of woolen yarn, in particular to a wool-sprayed hollow bag yarn. Background technique [0002] With the improvement of people's living standards, new changes have taken place in people's awareness of traditional thermal insulation or thermal insulation. It is no longer the idea that the thicker the fabric, the warmer it is, because this concept has been increasingly focused on comfort. Abandoned by people who are comfortable, casual, and fashionable; and now people hope that a light and warm fabric can appear. [0003] At present, the woolen yarns on the market are mainly carded, semi-worsted, worsted and fancy yarns, among which worsted yarns are the most widely used yarns. Worsted yarn can be fluffy and soft after being mixed with different raw materials. Because of the hand feeling, the twist of worsted yarn is generally relatively low, and the twist coefficient is between 2.0 and 2.5. The s...
