Towels are our daily necessities in daily life, but in reality, how much do we know about the ingredients and crafts of towels?
1. Now, in the factory woven towel, the ingredients are generally pure cotton, but the cotton here has a good texture and the level is high and low.
2, the thickness of the towel is generally measured by the weight of grams, the weight of the same size specifications is a few grams, the greater the weight of the towel, the thicker the thickness of the towel.
3, the production process of towels:
A, single-sided cut pile and double-sided cut pile
Generally, the most commonly used in our country is single-faced cut pile, which is not easy to drop hair. It is generally used as a sports towel. The cut pile is often used in the printing process to highlight the logo, and the embroidery is not practical.
B, jacquard process
Generally, the color of the towel yarn is less than two colors, which is more suitable for this process, and the embossed body is directly woven with the yarn to sense the logo effect.
C), plain weave
A very common weaving process, usually by screen printing or embroidery to highlight the logo.
4, the process of making towels:
First buy the corresponding yarn, then woven the yarn on the yarn, then dye, then print or embroider the logo, and finally sew the package.
The production process of the towel is briefly described as follows:
First, the cotton cleaning process
1, the main tasks:
(1) Loosening the pressed fibrils into smaller fiber blocks or fiber bundles for smooth mixing and impurity removal;
(2) Remove most of the impurities in the fibrils, defects and short fibers that are not suitable for spinning.
(3) The different batches of fibers are thoroughly and uniformly mixed to ensure the quality of the cotton yarn is stable.
(4) Rolling: A cotton fiber roll with a certain weight, length, uniform thickness and good shape.
Second, the carding process
1, the main task
(1) Parting: The fiber is decomposed into a single fiber state to improve the straightness and parallel state of the fiber.
(2) Mixing: The fibers are further sufficiently uniformly mixed.
(3) Forming: making a sliver that meets the requirements.
Third, the combing process
main mission:
1. Remove impurities: remove fine fiber defects in the fiber.
2. Carding: further separating the fibers, eliminating short fibers below a certain length, and increasing the length uniformity and straightness of the fibers.
3. Drafting: The cotton sliver is drawn to a certain thickness and the parallel straightness of the fiber is increased.
4, into a strip: made of cotton slivers that meet the requirements.
Fourth, the drawing process
main mission
1. Combining: Generally, 6-8 fiber strips are used for the combination to improve the uneven length of the sliver.
2. Drafting: The fiber strip is elongated and drawn to a prescribed weight, and the degree of parallelism of the fibers is further increased.
3. Mixing: The fibers are further uniformly mixed by using the combination and the stretching, and the fiber strips processed by different steamed breads and different processes are mixed on the draw frame.
4, into a strip: made into a strip of well-formed cooked strips, regular grid in the sliver barrel for later use.
Five, roving process
main mission:
1. Drafting: The cooked strips are evenly stretched and thinned, and the fibers are further straightened in parallel.
2. Twisting: The drafting of the drafting strip is appropriately twisted back so that the sliver has a certain strength to facilitate the winding of the roving and the unwinding on the spinning frame.
Six, the spinning process
main mission:
1. Drafting: The roving is drawn to the desired fineness to make the fibers straight and parallel.
2, twisting: the strips are twisted back to become a spun yarn with a certain degree of strength and certain strength.
3. Winding: The twisted spun yarn is wound on a bobbin.
4, molding: made of a certain size and shape of the tube yarn, easy to handle and post-process processing.
Seven, winding process
main mission:
1. Winding and Forming: The bobbin (line) is wound into a bobbin having a large capacity, a good shape, and a certain density.
2, remove impurities: remove some defects and impurities on the yarn to improve the quality of the yarn.
Eight, twisting process
main mission
1. Twisting: Two or more single yarns are combined and twisted to form a strong and well-structured strand.
2. Winding: The twisted strands are wound on a bobbin.
3, molding: made of a certain size and shape of the pipeline, easy to handle and post-process processing.
Nine, warping process
Tasks and requirements
1. The task of warping:
According to the design of the process design, a certain number and length of warp yarns are taken out from the winding bobbin to form a piece of yarn, so that the warp yarns have a uniform tension, and are closely wound on the warping axis in parallel with each other to form a weaving. The shaft is ready for preliminary preparation.
2. Requirements for warping:
(1) The warp yarns must have an appropriate tension during warping while maintaining the elasticity and tension of the warp yarns as much as possible.
(2) During the warping process, the full-width warp yarns should be as uniform as possible.
(3) The warp yarn arrangement and winding density on the warp yarn axis should be uniform (refer to the warp beam transverse direction and the inner and outer layer yarns), and the warp beam surface should be positive, without unevenness.
(4) The warp number, length or color warp arrangement cycle must meet the requirements of the weaving process design.
Ten, sizing process
Mission and requirements:
When the warp yarn is woven on the loom, it is subjected to the repeated rubbing action of the heald, the cymbal, the dropper, and the like, and the tension of the opening is constantly changing. The warp yarn of the final pulp, because many hairs are exposed on the surface of the yarn, when the looms are repeatedly subjected to friction and tension, the hairiness on the yarn will loosen and fluff, and some of the fibers will separate from the yarn, and finally the warp will be broken. Head, this not only increases the breakage rate of the loom, reduces the number of workers' stands, but also affects the quality of the cotton.
In order to reduce the breakage rate on the loom, the warp yarns are subjected to sizing engineering, so that the warp yarns have greater smoothness and fastness. The sizing process is a warp yarn on several warp beams and is passed through a slurry to pass through the slurry. Pressing, drying, and winding into a woven shaft.
After the sizing of the warp yarn, the smooth protruding fiber adheres to the strip of the yarn due to the slurry, thereby improving the smoothness of the yarn, and at the same time, the slurry is dried to form a slurry film on the warp yarn, thereby increasing the warp yarn resistance. On the other hand, the slurry penetrates into the warp yarn to adhere some of the fibers to each other. When the yarn is stretched, the table hinders the mutual movement of the fibers in the yarn, thereby increasing the strength of the warp.
XI. Through the process
It is the last process in the warp preparation project. The task of the warp is to pass the warp yarn on the weaving shaft through the dropper, the heald and the weir according to the requirements of the fabric, so as to form the shed when weaving, and introduce the weft into the desired fabric, so that the warp is broken. Timely parking can not cause woven fabrics.
Twelve, weaving process
Weaving is an important process in textile mills. The task of weaving is to interlace the warp and weft yarns processed by the preparation process into a fabric according to the fabric specifications according to the fabric specifications according to the fabric specifications. The production, quality and consumption of the weaving process directly affect the economic benefits of the enterprise and must be highly valued.
1. Improve product quality.
Fabric quality mainly includes two aspects of the physical properties and appearance of cotton. The physical properties of the fabric, such as the warp and weft strength of the fabric, the abrasion resistance, the air permeability, etc., directly affect the take-up and wearing fastness, and should be determined according to the different uses of the fabric. And to control in the whole process of production, to meet the requirements of the index. The appearance of the fabric is as follows: creases, sparse, hundred feet, flower jumps, holes, etc., which not only affect the appearance of the fabric, but also have a direct impact on the performance and wearing fastness. The work method should be strictly implemented in the operation process. In the daily management, the factors generated by the defects should be analyzed frequently, and the improvement measures should be proposed in a targeted manner to continuously improve the quality of the finished products and improve the first-class product rate.
2, improve production efficiency
The production efficiency of the loom is one of the evaluation indicators used to measure the production level. During the operation of the loom, due to the warp, weft breaking, mechanical failure, handling of bad cloth, upper shaft and other reasons, the machine is stopped, which affects the output of the cloth machine and the quality of the cotton cloth. Therefore, effective measures must be taken to reduce breaks, reduce mechanical failures, timely stop the platform, shorten the stoppage time, and strive to improve the production efficiency of the loom.
3. The main material consumption of the weaving machine in the weaving process is machine material, yarn and power. The amount of consumption is related to the quality of raw material equipment, technical operation level, production environment and production conditions. Reducing material consumption is an important part of improving economic efficiency and must be highly valued.
Thirteen, grey cloth dyeing
main mission:
1. Remove the stained area of the grey fabric during the sign-in process by simple scouring, and at the same time achieve a better color uniformity of the grey fabric.
2. The dyeing treatment of the grey fabric is carried out by active environmental dyeing to achieve the color required by the customer.
3. Washing after dyeing to ensure that the grey cloth reaches the neutral requirement when it exits the cylinder.
Main requirements:
1, the color is saturated, bright, or meet the special requirements of customers.
2. The grey fabric must meet the requirement of PH=7, that is, reach neutrality.
3, without any color, color spots and other phenomena.
Fourteen, towel finishing
main mission:
1. Punch the dyed towels and classify them.
2, according to the requirements of the towel sewing, according to the customer's requirements, the general sewing is divided into long strips of normal side, three needles and five lines, double needle side and so on.
3. The sewed towel is inspected, mainly for trimming the thread at the time of sewing, and classifying at the same time. The classified first-class products are transferred to the packaging process, and the second-class products and repaired items are transferred to the inspection process for maintenance.
4. The main task of the maintenance process is to repair the towels that can be repaired, to continue the packaging process that can achieve the first-class products, and to classify and package the products that are not up to standard (special or third-class).
5, the packaging process transfer task is to carry out the packaging of the goods according to the customer's requirements, until the final packing into the warehouse.
The above is the process of the towel introduced by Xiaobian for everyone. In fact, the process of a small towel is very complicated. It is very difficult to ensure the final quality of the towel while completing each process.
