  Abstract:In order to reduce the spinning cost，Xinjiang cotton is used to develop different levels of unbleached cotton combed yarn，and the research progress and product characteristics of unbleached cotton semi-combed yarns are analyzed.Taking the C 22.4 tex semi-combed K yarn as an example，the key technology of compact spinning unbleached cotton semi-combed yarn is discussed in the process flow，raw cotton selection，technological measures of each process and spinning index comparison.It is pointed out that the unevenness，slubs and neps of compact spinning semi-combed yarn are superior to those of general carded yarn in quality.Compared with pure combed yarn，the cotton consumption per ton of semi-combed yarn with 30% combed content can be reduced by 0.2 t，and the yarn index is better than that of general combed yarn and worse than that of combed yarn.The CV value of yarn unevenness decreases with the increase of combed content，and the change is significant.When the requirement of yarn unevenness，fine end and neps of yarn is not high，reasonable selection of raw materials and use of lower content of combed yarn can reduce the cost and improve the added value of semi-combed natural yarn.
Key Words:combed；semi-combed；compact spinning；Xinjiang cotton；evenness；strength；cost
