Problems solved by technology

However, cotton fiber also has many disadvantages: more hairiness, easy to pilling, high humidity and heavy sweating, it cannot conduct moisture, forming sticky paste, large heat release during moisture absorption, slow drying after wet, poor shape retention, poor wrinkle resistance, Especially after washing, the wrinkles are serious and ironing is required; the flame retardancy is poor; the strength is low, the wear resistance is poor, and the service life is short
The dry strength of cupro fiber is close to that of viscose fiber, but its wet strength is higher than that of viscose fiber, and its abrasion resistance is also better than that of viscose fiber. It has four functions: breathing, refreshing, antistatic, and good drapability. The disadvantage is that it is relatively expensive

Embodiment Construction

[0020] 1. Raw materials: 60% tencel by mass, 25% cotton and 15% cupro ammonium, weaving tencel cotton cupro ammonia fiber by blending eddy current spinning.

[0021] 2. Spinning process flow: Tencel, cotton and copper ammonia pass through FA002A automatic cotton grabbing machine → FA022 multi-storey cotton blending machine → FA106A cotton opener → FA046A vibrating cotton box feeder → A076F single beater lapping machine → After the FA224B carding machine, it goes through the HSD961 draw frame (one parallel, two parallel)→TD03-600 draw frame (three parallel)→MVS861 vortex spinning machine.

[0022] 3. Technical points of the main process technology:

[0023] 3.1. Opening and cleaning process: Tencel, cotton and copper ammonia are respectively opened and cleaned according to the principle of "low speed opening, less beating, less falling, and anti-sticking rolls". The beating speeds are 550r / min, 500r / min and 450r / min respectively The quantitative wet weights are 480g / m, 400g / m ...

Abstract

The invention discloses a vortex spinning technology with Tencel, cotton and cupro blended. The blended yarn includes, by mass, 60% of Tencel, 25% of cotton and 15% of cupro; after opening and cleaning and carding are conducted on Tencel, cotton and cupro respectively, the yarn is spun through drawing and vortex spinning technologies. The composite fibers have the advantages of good elasticity, high wet-and-dry strength, soft hand feeling, elegant gloss, low cost and the like, and have the functions of good moisture absorption and releasability, antistatic property, good drapability and good hydrophilic property.

Description

technical field [0001] The invention relates to the technical field of blended yarns, in particular to a tencel cotton-cupro-ammonia blended vortex spinning process. Background technique [0002] Tencel is a kind of cellulose fiber. It adopts solvent spinning technology. The dry strength is slightly lower than that of polyester, but it is obviously higher than that of ordinary viscose fiber. The wet strength is significantly improved compared with viscose. It has very high rigidity and good Dimensional stability after washing (shrinkage rate is only 2%), high hygroscopicity, round or oval fiber cross section, beautiful luster, soft hand feeling, good drapability, good flow, cheap price, and has the characteristics of cotton Softness, high strength of polyester, and warmth retention of wool, but it tends to harden under hot and humid conditions, and the fleece performance in cold water is not good. [0003] Cotton is an important raw material for the textile industry. It ha...
