Development history of textile machinery

Humans originally used natural fibers as raw materials for spinning and weaving, earlier than the invention of the text (see World Textile History, Chinese Textile History). China used hand-spinning spinning in the Spring and Autumn Period and the Warring States Period. In the Song Dynasty, it has invented more than 30 spindles of hydraulic spinning. In 1769, the British R. Ark Wright (also translated by Richard Acklet) made a hydro-spinning machine. In 1779, the British S. Crompton (Samuel Crompton) invented the spinning machine. After being introduced to the United States, American J. Thorpe invented the ring spinning machine in 1828, which increased productivity by several times due to continuous spinning. The loom in the Warring States Period of China has used the principle of leverage to drive the heald frame to complete the opening action with the pedal link. In 1733, the British J. Kay (also translated by John Kay) invented the shuttle, hitting the shuttle to make it fly at a high speed, and the productivity of the loom was doubled. In 1785, the British E. Cartwright (also translated by Edmont Carterett) invented the power loom. In the same year, the UK built the world’s first steam-powered cotton mill, which was the textile industry from the handicraft industry to the big industry. A turning point in the production transition. The progress of human society and the increase of population have promoted the development of the textile industry and correspondingly promoted the improvement of textile machinery. Energy reform (replacement of manpower and animal power with steam power) laid the foundation for modern textile machinery.
The advent of man-made fibers at the end of the 19th century broadened the field of textile machinery and added a category of chemical fiber machinery. The demand for synthetic fibers has increased, and the expansion of synthetic fiber spinning equipment has been promoted (spinning screw diameters up to 200 mm, daily production of single spinning machines to 100 tons) and high speed (spinning speeds of 3,000 to 4,000 meters). / points) direction development. In the fastest growing countries in the world’s synthetic fiber industry, equipment is renewed in almost 5 to 6 years, and the number of machines has doubled in 10 years. In the past 20 years, the spinning and weaving equipment has made many local improvements to adapt to chemical fiber pure spinning or blending with natural fibers, such as expanding the range of suitable fiber length of the drafting mechanism and eliminating static electricity on the fiber. In the dyeing and finishing, high temperature and high pressure dyeing equipment, heat setting equipment, resin finishing equipment and loose finishing equipment have been developed.
Humans have been spinning and weaving in the traditional way for more than 6,000 years. The spinning and weaving machine designed to the present principles is still the main equipment of the world textile industry. However, since the 1950s, some new processes have been created, partially replacing traditional methods to produce textiles with much higher efficiency, such as rotor spinning, non-woven fabrics, and the like. The new process bred new textile equipment, and the new textile equipment matured and promoted, which further promoted the textile industry to move forward.

Fabric Strength Testing

Fabric Strength Testing with a Universal Testing Machine

Textiles, yarn, thread, fabrics, wool, cotton, and other animal and plant-derived fibers are commonly tested to ensure product quality by assessing the performance of materials and making sure they are acceptable towards proper end-use. This blog post will cover certain mechanical testing methods to test fabric and go over the testing standards as well as the recommended equipment.

Measurement Methods of the Mechanical Properties of Fabrics
Tension Testing
Tensile testing is the most commonly applied test method for analyzing the mechanical properties of fabric materials. Although the direction of applied force is always in tension, there are a variety of tensile test methods available for capturing the most relevant data for final product usage.

The strip test is a tensile test in which the full width of the test specimen is gripped in the tensile grip jaws of a universal testing machine. During this test, tensile force is applied on the fabric specimen until it ruptures. Mechanical properties to analyze include the force at rupture and the elongation (expressed as percentage) at maximum force and/or at rupture.

Trapezoidal tear is another tear strength test that uses a specimen prepared as an isosceles trapezoid with a small cut on one side. When testing starts and force is applied, the trapezoid tear produces tension along a reasonably defined course such that the tear propagates across the width of the specimen. This test method applies to most fabrics such as woven fabrics, air bag fabrics, blankets, napped, knitted, layered, and pile fabrics.

Adhesion Coating Testing
Adhesion coating testing is applicable to fabrics with an adhesive coating compound applied, forming a chemical bond between the adhesive and the fabric material. The bond strength that is created between the coating compound and the fabric material can be measured running adhesion coating tests. If the adhesion is not strong enough, seam strength will decrease. If adhesion is too strong, problems may arise as tear strength will be affected. Standards outlining the minimum required criteria for specific fabric constructions can be used to ensure both the seam and tear strength are acceptable.

Puncture/Burst Testing
Puncture testing of fabric specimens determines the strength of a material by measuring the force required to penetrate the specimen. Contact with sharp edged objects in a real-world scenario is simulated by the use of puncture fixtures. Puncture fixtures are often used in the tensile direction but may also be used in the compressive direction. In order to calculate the specimen puncture resistance, the specimen is first stretched and placed on the ring clamp mechanism of the puncture fixture. Load is then applied by the puncture probe until specimen rupture.

The reason for the formation of fabrics weaving machine

(1) Wrong Yarn

Exterior: In the hairs of knitted fabrics, transversely continuous terry loops are woven from coarser or finer yarns than those of standard yarns. Generally, they are generally single, but even those that are juxtaposed or spaced are more compact and thicker. Normal people are different.

Causes: When weaving knitted fabrics, operators mistakenly use non-specified yarn counts or denier yarns to weave misuse of finer yarns. As a result, fabrics appear thinner and misuse of thicker yarns.

(2) Wrong End

Appearance: The warp of the woven fabric has a single or side-by-side number of non-specific specifications. If it is a fine yarn, it is called Fine End. If it is a thicker yarn, it is called Coarse End.

Contributing factors: The number of bobbin yarns involved in the warping of menstruation during the warping period is wrong, and the use of warp yarns of non-specified specifications is often the case of full-match persons.

(3) Wrong Pick

Appearance: The weft of the woven fabric has one or more non-specified thicknesses. For finer yarns, FinePick is called. If it is a thicker yarn, it is called coarse weft.

Causes: When weaving, the weft yarn of the weft tube, or the number of bobbin yarns fed by the shuttleless weaving machine is wrong. It is not easy for the weaving machine that uses the non-specified weft yarn operator to remove and stop the machine after it is found and then automatically changes the tube. Find.

(4) Wrong Weaving

Appearance: The weave method is wrong. The texture of the fabric is different from the original designer. For example, the left twill weaves into the right twill.

Causes: Most of the errors are due to mistakes in jacquard fabrics, errors in warp yarn arrangement in multi-standard warp fabrics, etc.

(5) Wrong draw

Exterior: The two warp yarns that are adjacent to each other are regarded together as one woven into the cloth by the fabric organization. The root (actually two) yarns appear to be particularly thick. When the initial weaving of the shaft is found, the elimination of one of the roots can be completely avoided.

Roll slitting

Roll slitting is a shearing operation that cuts a large roll of material into narrower rolls. There are two types of slitting: log slitting and rewind slitting. In log slitting the roll of material is treated as a whole (the ‘log’) and one or more slices are taken from it without an unrolling/re-reeling process. In rewind slitting the web is unwound and run through the machine, passing through knives or lasers, before being rewound on one or more shafts to form narrower rolls. The multiple narrower strips of material may be known as mults (short for multiple) or pancakes if their diameter is much more than their width. For rewind slitting the machine used is called a slitter rewinder, a slitter or a slitting machine – these names are used interchangeably for the same machines. For particularly narrow and thin products, the pancakes become unstable, and then the rewind may be onto a bobbin-wound reel: the rewind bobbins are much wider than the slit width and the web oscillates across the reel as it is rewound. Apart from the stability benefit it is also then possible to put very long lengths, (frequently many tens of kilometres), onto one bobbin.

Cloth folding machine

Cloth folding machine is a kind of finishing equipment in industrial washing machines. It began to be used in China in about the early 1980s. It was mainly used in five-star hotels and some large-scale professional laundry factories. At the time, almost all of them were imported equipment. Some manufacturers in China began to produce folding machines in the 1990s, mainly imitation of foreign sheets folding machines. Until 2008, only manufacturers in our country produced towel folding machines. By this time, there were more manufacturers of sheet folding machines. 2010 was the most prosperous year for the production and sales of folding machines in China. Large and small washing machine manufacturers have invested in the development or mass production, because in recent years due to the increase in labor costs, many laundry companies have a deep sense of the advantages of using a folding machine. In particular, some large-scale laundry plants, where thousands of towels and bath towels need to be folded every day, are labor-intensive, and the market opportunities for towel folding machines have arisen. However, the high price of imported towel folding machines has made many laundry companies prohibitive. This gave birth to the enthusiasm of some manufacturers in China to develop and produce towel folding machines. Maybe this is why the production and sales of folding machines are booming in recent years. However, the production and application of folding machines is still in its infancy in China, and there are still many gaps compared with foreign products. In terms of product performance, manufacturing process, especially in reliability technology, it is necessary to learn from foreign technologies, and it is still necessary to continuously improve and improve.
The earliest industry standard for folding machines in China was the Machinery Industry Standards of the People’s Republic of China, which was proposed and compiled by the Guangzhou Electronics Division in 1999: JB/T8962-1999 “Folding Machine” and JB/T8966-1999 “Folder Safety Requirements.” These two standards were approved by the National Machinery Industry Bureau in August 1999 and implemented in January 2000. This is China’s first standard for folding machines. In these two standards, the types, basic parameters, technical requirements, test methods, inspection rules, packaging, transportation and storage of the folding machines are separately specified. The safety requirements and test methods of the folding machine are applicable to a folding machine capable of automatically folding flat fabrics such as sheets and tablecloths after drying or ironing. Obviously, this is the standard for sheet folding machines. The standard for towel folding machines in China is not yet established.
