New "Total Testing" approach to ensure predictable profits

Quality control is no easy feat, especially amid the unrelenting cost challenge. To help textile manufacturers optimize production efficiency and reduce costs, Uster has developed the new Quantum 3 yarn quality assurance system, as well as its new "Total Testing" approach, which ATA Journalhad a glimpse at the company's stand at the recent ITMA 2011 exhibition in Barcelona, Spain.

Quantum 3: smart clearing technology

The Quantum 3 is Uster's latest clearer system that measures, analyzes and proposes how the yarn on the winding machines can be tailored to the spinner's quality and productivity needs, hence allowing textile manufacturers to optimize production efficiency and reduce costs. Equipped with new capacitive, optical and foreign matter sensors and powerful processing electronics, the system shows, for the first time ever, the full yarn body, that is, normal yarn with its set of expected tolerable natural variations. The new foreign matter sensor has multiple light sources to detect new colored foreign fibers and to help separation of colored foreign fibers from mostly non-disturbing vegetable matter. The contamination package of the product is completed by a brand new polypropylene clearing option.

Review on China's entry into WTO a decade later

It has been 10 years since China accessed to the WTO on 11 December 2001. During the decade, the Chinese textile industry has grasped the opportunities encountered, and proactively tackled various challenges. As a result, it has been dubbed the "textile manufacturing powerhouse". 

Weaving Process

Weaving is a method of fabric production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. The other methods are knitting, lace making and felting. The longitudinal threads are called the warp and the lateral threads are the weft or filling. The method in which these threads are inter woven affects the characteristics of the cloth.

The way the warp and filling threads interlace with each other is called the weave. The majority of woven products are created with one of three basic weaves:plain weave, satin weave, or twill. Woven cloth can be plain (in one colour or a simple pattern), or can be woven in decorative or artistic design.

Cloth is usuallly woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. Weft is an old English word meaning "that which is woven". A fabric band which meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back-strap, or other techniques without looms.

Weaving the way towards energy conservation

The recent debt crisis in the two major markets, Europe and the US, appears to have put the entire textile and apparel industry in an uncertain position. On top of that, massive pressures have mounted with the spiraling raw materials prices and labor costs. Under such circumstances, weavers in particular are struggling to survive. The most daunting challenge faced by textile weavers, according to Swiss weaving machinery maker Stäubli, is to respond quickly to the rapidly changing market demand, where there is already overcapacity in fabric production, and the prices are low. To help them improve their competitiveness, weaving machinery suppliers have worked to develop new technologies. But what is the leading direction for the development of weaving machinery? The latest developments in weaving machines lie in energy conservation, high productivity, high performance, flexibility, consistent fabric quality and versatility in terms of applications, said Dr Hua Tao, Instructor of Institute of Textiles and Clothing of Hong Kong Polytechnic University, at the recent Review Seminar on ITMA 2011 in Hong Kong. His views were echoed. "Energy saving and sustainability will continue to be important in weaving machinery's development. However, the machines must be easy to operate and maintain low price, durability and flexibility to produce not just one particular product but a range of products," noted Reinhard Furrer, Marketing & Sales of Stäubli Sargans Ag.

India's cotton output likely to reach 340 lakh bales in 2011-12 season

The Cotton Association of India (CAI) expects that in 2011-12 season, India's cotton output will be at least 340 lakh bales (34 million bales), but its consumption will probably be below 250 lakh bales (25 million bales), Indian media reports.

CAI President, Dhiren N Sheth, was quoted as stating that favorable seasonal conditions for cotton in the previous season (2010-11) encouraged Indian farmers to boost the acreage for cotton cultivation, and with hindsight of price hikes in the 2009-2010 season, Indian famers used extra area for cotton cultivation.

High Speed Spindles Technology HP-S 68 (Novibra)

IntroductionA textile spindle is a device with oscillatory properties which, depending on the speed of rotation due to its unbalanced state, is vibrationally excited.
The spindle can be described as a spring-mass system with a damping device proportional to rotation speed. The running performance of a spindle is directly influenced by the individual bending stiffness and the damping characteristics of the system.
For spin-technological reasons a quiet run of the spindle, concentric to the spinning ring and with minimum amplitudes at the top of the spindle, is required.
All spinning spindles are operated in the hypercritical speed range. The first critical speed is, according to spindle design, between 2,000 and 4,000 rpm. This speed is only relevant during the start of the machine. The occurrence of a second critical speed within the working speed range of the spindle must be avoided at all cost. Apart from other factors, this is achieved by making the spindle upper part sufficiently resistant to bending deflections.
HP-S 68 Spindle Design
Modern spindles must be designed for spindle speeds above 20,000 rpm. The special aim is to ensure that belt or tape speeds do not increase in the same ratio as the spindle speed. The objective is therefore to reduce the wharve diameter still further. This can only be achieved by reducing the dimensions of the neck bearing and, consequently, the shaft diameter of the spindle upper part. Smaller spindle shaft diameters with otherwise the same bearing dimensions are however less rigid.
As mentioned above, a reduced stiffness of the spindle upper part would have a negative influence on the running performance of the spindle. Consequently, when reducing the diameter of the spindle shaft of HP-S 68 spindle to 6.8 mm, the distance

Guru SMKN Tegal ciptakan robot pembatik

Agus Martoyo, guru Sekolah Menengah Kejuruan Negeri (SMKN) 1 Tegal, Jawa Tengah, berhasil menciptakan robot pembatik yang mampu mempercepat proses pembuatan pola batik tulis dengan hasil produksi lebih tinggi dibanding proses manual.

"Robot itu kami namakan Robotika Machine 7NG-1110. Ini kami buat untuk mempercepat proses membuat pola secara langsung di atas kain tanpa menggunakan alat gambar manual," kata Agus Martoyo, guru mata pelajaran Elektronika dan Mesin SMKN 1 Kota Tegal di pameran Usaha Mikro Kecil dan Menengah (UMKM) 2011 di Alun-alun Kota Tegal, Minggu.

Guru kelas sekaligus pencipta mesin robot batik tersebut mengatakan, ide awal menciptakan robot batik berawal dari keluhan sejumlah pengusaha batik tulis yang kesulitan membuat pola sehingga muncullah ide menciptakan mesin yang dapat membubuhkan cairan malam ke kain dengan corak tertentu.
