Embodiment 1

[0013] Include the following steps

[0014] 1. Use the FA231 carding machine bundle, and carry out carding, impurity removal, and uniform mixing under the conditions that the licker-in roller speed is 1200 rpm, the cylinder speed is 350 rpm, and the doffer speed is 24 rpm. into 360g / 100m fiber strips;

[0015] 2. Use the Dref-II type friction spinning machine to spin, and feed the fiber sliver obtained in step 1 into the spinner of the friction spinning machine. Roller rotating speed is 4000 rev / mins, and dust cage diameter is 81mm, and rotating speed is 3500 revs / mins, and yarn twist is 500, makes the Lisa fiber yarn of 110 (tex).

Embodiment 2

[0017] 1. Use the FA231 carding machine bundle, and carry out carding, impurity removal, and uniform mixing under the conditions that the licker-in roller speed is 1250 rpm, the cylinder speed is 280 rpm, and the doffer speed is 21 rpm. into a fiber strip of 380 g / 100 meters;

[0018] 2. Use the Dref-II type friction spinning machine to spin, and feed the fiber slivers obtained in step 1 into the spinning device of the rotor spinning machine. Comb roller rotating speed is 4200 rev / mins, and dust cage diameter is 81mm, and rotating speed is 3200 revs / mins, and yarn twist is 520, makes the Lisa fiber yarn of 100 (tex).

Abstract

The invention discloses a Richcel fiber yarn producing process and belongs to yarn producing techniques. Richcel fiber yarn spun by conventional ring spinning has the defects of difficulty in yarn spinning and poor quality of resultant yarn. A novel friction spinning technique is adopted and includes using a carding machine for tow-to-top conversion, carding, removing impurities and uniformly mixing under the condition that licker-in speed is 1200-1250rpm, cylinder speed is 280-350rpm and doffer speed is 21-24rpm, and obtaining fiber strips of 350-380g / hm; using a friction spinning machine for spinning, namely, feeding the fiber strips produced in step 1 into a rotor spinning machine, wherein a sawtooth carding roller is used, the diameter of the carding roller is 81mm, the rotating speed of the carding roller is 2800-4200rpm, the diameter of a dust cage is 81mm, the rotating speed of the dust cage is 1000-3500rpm, the yarn twist factor is 500-550, and obtaining the Richcel fiber yarn of 100-200(tex).

Description

technical field [0001] The invention belongs to the technical field of yarn manufacturing, and in particular relates to a manufacturing process of a Lycell fiber yarn. Background technique [0002] Lisai fiber is called "vegetable cashmere" by the industry. It is a plant cellulose fiber with excellent comprehensive properties. It has good curl and good warmth retention. The initial modulus is large and the resilience is good. Using this property, it can be made into wool-like sweater fabric with good bulkiness and full hand feeling. It has good hygroscopicity, and the fabric woven from it has good moisture permeability and air permeability, and is non-irritating to human skin, and is soft and smooth. Its dyeing is bright and lustrous, and the fabric formability is good. The surface of Lisa fiber is smooth and soft, and the fiber cohesion is poor during the spinning process, and it is easy to adhere to the machine parts. During the spinning process, there are many flying fl...
