Zhen Lun Cotton Spinning: Good Quality Yarn With Customer Satisfaction.

The new mission is pressing ahead, and the new voyage is sailing.

In recent years, the company has taken the initiative to adapt to the new normal economic situation, and comprehensively promoted the pformation of equipment technology, replacing the old equipment with the most advanced spinning equipment in the world, and realizing the 100% self leveling and on-line detection of the production line.

Face

In the new environment, the company proposes to keep pace with the times, innovate the core power, focus on the management concept of "fine, thin and solid", vigorously carry forward the "craftsman spirit", do fine and excellent "Zhen Lun" brand yarn, and improve the product quality in an all-round way.

As a manufacturing enterprise, the improvement of product quality is endless.

With the continuous expansion of the company's capacity, we need to constantly expand and expand new markets to attract more customers.

Product quality is the demonstration of the overall quality of enterprises. Modern enterprises pursue the combination of high quality and high efficiency. They not only require high internal and external quality of yarns, but also satisfy the weaving efficiency with high efficiency.

Therefore, to further improve product quality and make good quality yarn with user satisfaction is our eternal pursuit of "Zhen Lun Ren".

Cotton spinning is a multi process and continuous production process. It is characterized by "more than 3", that is, many machines and equipment, many workers, and a large number of semi-finished products and finished products.

Every tiny link in the production process will bring different effects on product quality, production efficiency, raw materials and energy consumption, and sometimes even produce serious consequences.

The stability of quality is very important to both producers and customers.

For example, in a batch of products, even if 99% is superior, of which 1% of the quality has a flaw, customers will often negate 99% by 1%.

Therefore, in the production process, we must strictly control the difference of the quality of single ingots (such as CVb, thick section, long detail, neps, Mao Yu, etc.) which have great influence on the quality of cloth.

At the same time, we must attach great importance to the appearance quality of the products. Even if the quality of the yarns itself is up to the advanced level of 5%-25%, but due to the poor appearance quality or the quality problems of the paper tube, the problem of unwinding, or the adhesion and contamination of individual cylinder yarn, or the accidental damage and hang up during the package pportation process will affect the customer's evaluation of the product quality.

In addition, the quality of yarn used by the customer will be evaluated according to the style and use of the actual fabric.

How to ensure the stability of yarn quality in the whole process and do the best quality yarn that users are satisfied with is discussed in the following aspects.

Quality yarn standard 1: index quality

Index quality refers to the quality data obtained through testing instruments.

For yarns, the evenness, thickness, knots, Mao Yu, strength, weight irregularity, strength irregularity, elongation and twist are all reflected.

The main data of index quality.

Therefore, paying attention to the quality of indicators is the basis for the company's staff to do well in product quality requirements.

The quality of indicators is judged by the Ulster communique.

The Ulster Communique is a reference index for grading the quality of fibers, slivers, roving and yarns in the world's textile industry.

USTER statistics are generally divided into 5%, 25%, 50%, 75% and 95% files.

Usually 50% of the statistics are general level, 25% and below are advanced level, and 75% and above belong to a lower level.

Yarn production plants, weaving mills and knitting mills all make quality indicators according to the USTER statistics.

High quality yarn standard two: physical appearance quality

Physical appearance quality covers two aspects of yarn appearance and cloth appearance.

The appearance quality of yarn mainly includes the appearance quality of finished products and the appearance quality of finished yarn.

The appearance quality of finished products refers to whether the outer package is damaged, worn or broken. Whether the outer package and batch number are correct, whether the woven bag, the tube yarn moon bag is used correctly, and whether the color of the paper tube is used correctly.

The appearance quality of finished yarn refers to whether there are oil stains on the surface of the cylinder yarn, the web of cobweb, soft yarn, bad yarn, bad yarn and yarn. There are obvious silk flying flowers attached to the tube yarn, cotton yarn and other mixed species on the surface of the yarn.

The appearance quality of cloth refers to the smoothness of the cloth, the color difference between the sides of the cloth, the thickness of the cloth, and the neps.

High quality yarn standard three: customer standard

Household standard is divided into general customer quality standard and special high-end customer quality standard.

At present, the market demand is becoming more and more detailed, and customers' requirements for product personalization are highlighted.

Some customers pay attention to yarn hairiness and require smooth cloth. Some customers pay attention to the evenness of yarn lines, and require high requirements for Saiko Sa. Some customers require fabric to feel soft.

In this regard, we need to produce yarn that meets customer requirements according to the different uses of yarns.

For example, the multi hairiness yarn spinning line, soft Siro compact yarn, high twist ring spinning, air spinning, Siro compact spinning line, and various rolls that meet different rewinding requirements.

The quality standard of special high-end customers, in addition to the general requirements of customers, but also for yarn evenness, Mao Yu, cotton and uneven strength, Twist Unevenness put forward more stringent requirements.

Especially for users who make mouth yarn and domestic white cloth and dyed light color and bleach, there are more stringent requirements on the surface, such as dirt, oil, fiber and dust.

Measures to ensure high quality yarn

As we all know, the progress of spinning mills can not be achieved overnight. The decline of the spinning mill is also not a cold day. The optimization and deterioration are reflected in the accumulation.

In order to achieve comprehensive control of spinning process and make good quality yarn, we should start with raw materials, semi-finished products and finished products.

Strengthening operation management, strictly implementing operation requirements, correcting illegal operation, and strengthening cleaning work of machine channel in each process to reduce yarn defects.

The existence of yarn defects not only affects yarn quality, spinning production efficiency, but also affects the quality of cloth.

Spinning mills should not only attach importance to five conventional indicators, but also pay attention to the number of yarn defects of one hundred thousand meters.

The harmful yarn defects in textile process mainly come from flying flowers. For the pre spinning process, effective reduction of short fiber and improvement of workshop environment are the key factors for prevention.

It is necessary to reasonably set the technological parameters of electric cleaning, properly reduce and control the formation of harmful yarn defects, and effectively control the yarn defects in a certain range, which not only meets the requirements of woven yarn, but also meets the requirements of knitted yarn for cloth yarn defects.

Strict implementation of equipment cycle management.

Strict selection, periodic replacement and daily record of specialized textile equipment.

For the newly selected spinning equipment, we need to track and observe the effect of this component on the quality.

We should choose a cost-effective and long life for special parts of different manufacturers.

。

Import good raw materials.

First of all, raw materials, cotton and cotton should be used.

The quality inspection of the raw materials (appearance, packaging, moisture regain, internal quality, etc.) should be paid enough attention.

Do process optimization test.

The purpose of spinning process test is to find out the problems and defects in production, to study the causes of the problems, to guide how to solve them in the production process, and how to avoid such problems happening again in the future production.

The technicians should correctly use the test instruments and the on-line monitoring function of the workshop.

For example, the electrical defects of the winding, the fault of the vortex spinning and the cause of the alarm can directly reflect the quality fluctuation of the yarn.

The setting of winding and vortex spinning directly affect the quality of output.

In this regard, the consistency of product quality requires that the same species must set the same parameters.

Control the quality of semi-finished products.

The quality of semi-finished products directly affects the quality of yarn. How to control the quality of semi-finished products from raw materials to yarn processing is an important link in the process of production management.

Such as raw sliver, semi cooked bar, appearance of the strips, scraping, scraping, oil stain, appearance defects, coarse and unevenness of roving, poor forming, appearance of yarn, uneven yarn, cotton wool and feather yarn, thick and thin sections, bad winding forming of winding, pressure marks on the surface of cylinder yarn, addition of silk, oil pollution, cobweb, cross edge, yellow and white difference, all of which are factors affecting the quality of semi-finished products.

Grass-roots managers at all levels must examine every aspect carefully and carefully, without letting any detail affect quality.

Control the quality of finished products.

The quality of product packaging is the most intuitive first impression of the customer's yarn quality.

The finished product has good appearance quality, and it is necessary to ensure that the position of the tube yarn is fixed in the woven bag.

Secondly, the quality of winding and the quality of the tail can directly affect the efficiency of the customer, and it is also a quality project that customers emphasize very much.

The size of the bobbin is also an important factor in deciding the amount of work done by the customer, so it should be as large as possible within a reasonable range.

Effective control of air conditioning, air pressure, dust removal system.

Adjust the temperature and humidity of the workshop at any time according to the weather changes to ensure that the spinning requirements are met.

In the operation of drawing, winding and vortex spinning, compressed air is used to finish spinning.

The stability of compressed air pressure directly affects the quality of spinning.

Regular cleaning and maintenance of the air conditioning system and dust removal system to ensure that the production requirements are met.
