When allocating cotton to key varieties of Wholesale Polyester Color Yarns, careful consideration should be taken to minimize the range of differences, that is, the average value of various indicators in mixed cotton should be controlled within the range, and the indicators of the two batches of cotton before and after replacement must be kept close. Based on the actual needs and possibilities, the replacements should be replaced according to priority, and the arrangements should be reasonable and appropriate so that the raw cotton ingredients used in each variety are not produced. As the fiber matures, the strength is high,
and the strength of the yarn is also large. Sometimes, although the raw cotton has some differences in properties, there is no harm to the quality of the yarn, but the quality can be improved. Although very primitive, it is more practical. Comprehensive cotton blending based on raw cotton in stock General cotton spinning mills called ’classification, queuing’ is an earlier method of cotton blending design. When blending cotton for general products, the range of indicators and differences can be relaxed, and only the average value of the main indicators of blended cotton should be within the specified range of differences.
Powerfulness has certain benefits. The index should not use a simple average, but should be weighted by weight percentage to find its average. For example: in the cotton blending component with shorter fibers as the main component, it is appropriate to match longer fibers, or in the cotton component with the coarser fibers as the main component, it is appropriate to mix with finer fibers to improve the sliver and yarn formation. Otherwise, although a little cotton is saved, the quality of the yarn is destroyed, and it will not be worth the loss. Many cotton spinning mills are still in use. (China Cotton Association).
In today’s information age, the use of computers for cotton blending is an inevitable trend in the development of cotton blending technology, and it can also bring the quality of finished yarn to a new level. If the raw cotton has a high short-pile ratio, the hairiness in the yarn is large (except for mechanical friction), and the yarn CV value is large; the raw cotton contains large impurities, many defects, and poor maturity. In addition, it must be mentioned that some of the return flowers produced in each process, such as broken cotton rolls, broken cotton slivers, roving heads, top roller flowers, bellows flowers, etc.

C should be Wholesale Polyester Color Yarns into account.6, and strive for a accurate sample. To understand the metamerism of a dye, make full use of a colorimeter to screen the dye.5 is required between the original and the sample. For example, European orders avoid red, which can be slightly green.
The combination of green FFB and yellow GCN in Shihlin dye did not decrease the light fastness, but still caused the brittleness of cellulose fibers. Therefore, after dyeing and staking out the sample after the finishing process, the shading should be adjusted to meet the customer’s requirements.
Buyers place an order for multiple textile operating companies to bid, and marketers place orders to multiple manufacturers to color patterns at the same time. When the color is just slightly cold after coloring, the green light should be slightly brighter, so that when the color light is stable, it is exactly equal to the original. Therefore, future colors can be described with numbers. When using a measuring instrument for color matching, generally △ E
Therefore, for enterprises, fast, accurate and well-printed swatches are the first step in winning orders. Because it is confirmed that the specifications of the fabric are the same as the large sample, it is easy to see the sample, the dye used is the same, and there is no ’jumping light’ phenomenon. It can choose three light sources to match colors at the same time, so you can get the optimal formula in a few minutes. Level 4. When flipping and replenishing orders,
the head cylinder confirmation sample is generally used as the reference to the original sample and the confirmation sample is biased to maintain the same batch of colored light. When Mart places orders in 2005, it will use data transfer to place color samples.

The influence and polyester raw materials manufacturers of combing cylinder on neps. 1) The noil rate should be determined according to the quality of the product, combined with the quality of the lint, neps and combed sliver. , But its effect is very large. Due to the limitation of the height of the top comb, the bottom fiber cannot be effectively combed.5 and +0.5 tex yarn, the noil rate is between 14% and 18%, and 26 teeth / 10 mm can be selected; for spinning below 10 tex yarn, the noil rate is between 10% and 25%, and 28 teeth / 10 mm can be selected ～ 30 teeth / 10 mm top comb. In addition, when the speed of the brush is constant, the diameter of the brush decreases and its linear velocity also decreases accordingly. Proper selection can reduce neps.1 mm.
The cleaning interval is generally set to 30 minutes, and each cleaning time is set to 10s. 4) In order to improve the carding effect, the automatic deceleration device of the comber is used reasonably. This not only stabilizes the rate, but also produces junctions and impurities. It is known through experiments that when the top comb is inserted at the same depth and the noil rate is equal, the top comb size has a certain relationship with the neps. . 6
Effect and control of the separation of the comber on the neps When the separation and the end of the combing, we found that the end of the comb that was combed by the top comb had more neps and large neps. Prevent crowding and reduce the increase of neps.5. 3) The surface of the rubber roller should be smooth, no concave core, no bending, and flexible rotation, and solid pressure. In the production process, we can turn the nipper to the front position, open the adjacent separation rubber roller pressure parts, and observe whether the depth of the top comb inserted into the tuft is moderate, otherwise we need to adjust.
The larger the noil rate of the same cotton roll, the less neps are present in the combed sliver, but the number of effective fibers in the noil rate should be considered. However, in actual production, the quantitative design of small rolls should not be too large, generally in the range of 60 g / m to 65 g / m, mainly considering the load on the cylinder needles and the relationship between the height of the top comb teeth and the thickness of the cotton layer.

When the installation is too low, the tip of the collection hook pierces the cotton net and even divides the cotton net into a striped path. The triangle airflow plate is slightly loose by 0. 4) The pressure of the separation rubber roller should be increased on the high-speed machine to ensure that the separation whisker is well held. 6)
Raw cotton fibers are short, and the triangle air flow board is not well controlled, which also easily causes loose edges of the cotton net. 2) If the rupture position of the cotton net is always in the same place, there may be serious impaction of debris on the lips of the upper and lower jaws. Analysis of reasons 1) Holes in the cotton net are periodic, appearing every clamp, and the cotton net does not rupture when driving at a slow speed. The cotton web is severely broken, and long fibers will also appear in the nodding cotton web on the surface of the dust cage. The rubber roller should be regularly ground and corrected for eccentricity during use, and there should be corresponding transfer procedures and assessment systems to ensure the quality of the rubber roller. 2)
Put the two inner and outer rubber rollers on top of each other and check whether the rubber roller surface is concave. Maintenance method 1) Improving the hardness of the separation rubber roller and increasing the clamping force of the separation jaw is a main method to eliminate holes in the cotton web. 3)
When the machine is polyester raw materials factory for a long time, the entire rubber roller should be released to prevent the rubber roller from deforming.5 mm, which can solve some loose edges. If there is such a phenomenon in production, it should be immediately stopped for maintenance. The opening of the cotton collection hook is too wide or too narrow, which will affect the cotton. Some cotton fibers on the two edges of the cotton are chaotically broken by the hooks of the cotton collection; some edges have a clear and thin road. When the speed is normal, the cotton net immediately has holes

In the spinning process, immature cotton fibers easily form a large number of hooks and cause many small yarn defects. Chance of falling off and hanging the wrong gear. Relatively, its defect removal load is relatively heavy. Pressurization failed. If the initial set of process parameters is more empty cut, there are more small yarn defects, and after relaxation, you can cut more large yarn defects, it means that the original process parameters are tight; if the initial set process parameters are less air cut, cut out large yarns There are many defects and few small yarn defects.
When setting the electro-clearing process parameters, the enterprise can set the initial electro-clearing process based on the inspection result of 100,000 meters of yarn defects, and then optimize the electro-clearing process parameters based on the 100,000-meter yarn defects of the package. Therefore, in order to reduce flying bamboo slub yarn defects, it is necessary to strengthen the standardization of operation and cleaning systems, the systemization of equipment maintenance and cleaning, and the systemization of special parts inspections, and implement them one by one. With the continuous development of electronic technology, the functions of wholesale DTY yarns electronic yarn clearers are becoming more and more powerful.
The focus is on analyzing the types and causes of yarn defects, and taking effective measures from process, equipment, operation, temperature and humidity to reduce yarn. Roller lock failure. In short, the setting of the electric cleaning process parameters should be in line with the inherent quality of the yarn and the user’s requirements. Method 2 Reasonably set up the electric cleaning process. It is better to match the cotton, not only to control the grade, length, and fineness of the cotton, but also to properly control the immature fiber content and short fiber content.
The spindle sinks. With the increasing internationalization of clothing enterprises and brand awareness, the market demand for defect-free yarns and defect-free cloths has prompted textile companies to become more stringent in the length and size of cotton yarns. Five key control items were identified for cause analysis.

The percentage of the difference between the length of the fabric before and after it is launched and its original length is usually called the shrinkage rate. For example, the dimensional stability of hand-washed samples is better than that of machine-washed samples, and the temperature of washing will also affect its dimensional stability. Reasons affecting shrinkage rate 1. Among them, the drip-drying method has the smallest effect on the size of the fabric, and the rotary arch drying method has the largest effect on the size of the fabric, and the other two are centered.
During the production and processing process, the fabric is inevitably stretched by the machine during the process of dyeing, printing and finishing, so that tension exists on the fabric. 3. The effect of the drying method of the sample on the shrinkage of the fabric is also relatively large. 2. 7. 8. For synthetic fibers,
high-temperature ironing will not only improve its shrinkage, but will damage its performance, such as fabrics that are hard and brittle. It is also possible to use hot air to heat the air at temperatures exceeding 100 ° C. Stress, in the static dry relaxation state, or the static wet relaxation state, or in the dynamic wet relaxation state and the fully relaxed state, the stress is released to varying degrees, so that the yarn fiber and fabric return to the original state.5%-5 5% of cotton polyester; 3% of natural white cloth; 3-4% of wool blue cloth;
Poplin is 3-4. In woven High Intermingled Yarns Suppliers, the shrinkage rate of general plain weave fabrics is smaller than that of flannel fabrics; while in knitted fabrics, the shrinkage rate of plain stitch structures is smaller than that of ribbed fabrics. Production process Different fabric production processes have different shrinkage rates. Therefore, when choosing clothing, in addition to selecting the quality, color, and pattern of the fabric, the shrinkage rate of the fabric should also be understood. For example, on the fabric, the radius of curvature of the fiber at the interwoven point of the fabric is increased, resulting in a shortened fabric length.

Everyone knows that pure cotton is good. This polyester DTY yarns manufacturers should be made of long-staple cotton. The identification of long-staple cotton fabrics may lead to flickering users. But master the following knowledge, you can judge true and false. Long-staple cotton will be silky smooth that ordinary cotton does not. Double mercerization is the mercerization of the yarn.When you buy bedding, you see that the fabric is cotton, but it reveals the luster of silk.
Reasonable process design requires careful operation of the maintenance workers. It is difficult to entangle each other due to friction during spinning, and it is not easy to adhere to the machine On the other hand, the content of short fluff in the blended cotton should not be too high. Everything must be combined with reality. Reducing harmful yarn defects is a regular basic work of cotton spinning enterprises, and it is also the main content of production process control and quality control. The quality of yarn defects is mainly determined by raw materials, processes, equipment, operations, temperature and humidity The key factor is to reduce yarn defects.
Two types of long-staple cotton are commonly used: Xinjiang long-staple cotton and Egyptian long-staple cotton; Egyptian long-staple cotton is the best grade of long-staple cotton and is known as ’white gold’. Long-staple cotton will only be used for high count and high density fabrics and high-end home textiles. Smoother: Good drape, silky smooth.
More breathable: good breathability and moisture removal, 5 times more breathable than ordinary fabrics. GIZA 45 is the best in terms of length and physical indicators, but its output is small. Softer: finer and stronger than ordinary cotton, better softness. More durable: wear-resistant and durable, good wrinkle resistance, not easy to pilling. Under the same thermal conditions, the growth period of long-staple cotton is 10-15 days longer than that of ordinary cotton. With the improvement of people’s living standards, the quality requirements for bedding products have become higher and higher
