China Colorful Yarn Company

He believes that in theory, the holding force is greater than the drafting force. The live broadcast time is short, and many exciting contents cannot be launched one by one. Yesterday, the state tightened the requirements for epidemic prevention and control, which added uncertainty to the on-site training courses held on May 11-14.

Zhao Jianwei will broadcast 'Analysis and Control Method of Yarn of Single-face Knitted Shabby Shade Yarn' on WeChat Group of Chief Teachers. The 'hard end' of the spun yarn will affect the quality of the spun yarn, the end of the yarn, the stand and mood of the driver, and the production efficiency. In serious cases, it will increase the management workload and production costs, so cotton spinning companies are particularly concerned. Increase the jaw gap; 3. Zhao Jianwei shared specific methods with practical cases. Throughout the lecture, teacher Zhao Jianwei actively shared and interacted with netizens with profound theories, empathetic cases and passionate language.From 19:30 to 20:45 on the evening of March 21,

the 'Chief Engineer WeChat Group' successfully held 'How to solve the problem of heavy weight, large twist coefficient roving in the spun yarn', deputy editor and chief senior consultant Zhao Jianwei In the live broadcast class, other textile WeChat groups are broadcast live simultaneously, and more than an hour of content has attracted 826 online learning.. Increase the pressure of the third 'upper roller' (Including repairing the cradle defect and increasing the diameter of the top roller); 4. Starting online China Colorful Yarn Company training courses on May 11, according to the situation of the epidemic situation, we will determine the time to go to Jiangnan University for 'actual combat + exchange + question answering +

team building + results review + issuance of certificate of completion' training, this model allows students to learn more in-depth , More thorough and more integrated! After we communicated with several students who have signed up, they all think this is better. Seven kinds of situations and causes, put forward six major solutions and the key points and attention links in the implementation process, and proved the effectiveness of the measures with examples, and introduced two enterprises

The weight of the roving is normal after tracking, and there is no abnormality in the corresponding spindle. According to the quality problems that occurred, the following aspects were investigated: 1. The size of the upper and lower aprons, upper pins, and spacing blocks; 4. Since the weight of the roving has not changed, the total draft multiple of the spun yarn is only 11.

The degree of attenuation and buffering of the fast-rotating torque (equivalent to the disassembly torque) transmitted by the middle roller jaws to the rear roller through the whisker depends entirely on the degree of easy stretching of the whisker. Various considerations when designing the drafting process must not violate the drafting principle. The greater the drafting force in the rear zone, the harder it is for the whiskers to be stretched, and the more effectively the forward torque is transmitted to the rear roller. In this case, you can appropriately enlarge the roller gap and increase the roving twist factor to increase the average draft force and reduce the fluctuation of draft force. It is necessary to keep the sliver continuous, stable and proper twist to improve the sliver of the finished yarn. (2) Increase the twist of the roving so that the whiskers entering the drafting zone of the spun yarn retain proper twist, thereby maintaining a better roundness of the whiskers.

The diameter and position of the front and rear rubber rollers; 3.), the roving twist can be appropriately increased without affecting the production. Spinning principle and technological analysis The essence of drafting is the process of increasing the distance of the fibers in the whisker and redistributing the fibers in a longer position along the axial direction. If the back draft is large, the number of fibers entering the front zone is even less, which is not conducive to fiber control. 1.

A company produces Sd Yarn polyester Dahua T21S all year round, polyester with 100% Yizhen Dahua 38mm×1. However, a serious quality problem occurred in the production process, and the user's opinion was great. Replacement of a new cradle; 6.35. In this process, the fibers in the sliver must be well controlled.56dtex, the quality is relatively stable.25, and the data returned to normal after the test. Of course, the roving weight should be set reasonably when making coarse yarn. Recently, I received orders for T10S and T8S. Due to the small amount, the roving weight remained unchanged at 6
