Anyone who wants to produce top quality woven goods in high volume, and wants to stay competitive in the bidding for orders, must first and foremost have their planning and organization under control. An additional criterion is thorough familiarity with the entire production process, from fibre to fabric, to ensure that fabric production is profitable.
A precondition of optimum production in the weaveroom is meticulous planning. It is at the planning stage that process parameters, sequences of operations and working conditions are defined, all of which are relevant to profitability. The basis for these is optimal installation of the weaving machines, with appropriate transport routes and equipment. Additionally, capacities must be planned and the necessary infrastructure and resources created, including buffer store, air conditioning, lighting, personnel, quality control etc. This article spotlights key points that it is essential to take into account in the planning and organization of a weaving facility.
Yarn Quality
High yarn quality ought to be a matter of course. But its importance has to be pointed out repeatedly, because 80% of weaving machine stoppages originates in upstream process stages. In non-verticalized mills, all yarns supplied should be inspected on receipt. Not only the uniformity of the yarn is important; damaged packages are a sign of poor transport quality, and on the weaving machine they not only impair productivity but also cause waste. If there are no yarn reserves in the weft packages the result will be a weft stoppage. Thread breaks in weaving are the largest cost factor in the entire production process, because they always involve a machine stoppage.
Proportion of the different departments in the total thread break costs
In the textile manufacturing process, thread break costs in weaving are far higher than in all other stages of production. Every stoppage prevented directly improves the company's profits.
After nearly five years in a space less than 75 feet square, University of Nebraska-Lincoln ‘s As the historic textile and historic costume collections are moved to what was once the International Quilt Study Center storage facility, space in the department is being released for other uses, and we'll continue to report on these as the various projects are finished up.The new space for the printer operation, nearly 275 square feet, has an integral humidifying system that maintains an optimum temperature of 71 degrees and a humidity level of 55%, ideal for best printer performance.In addition, the Jacquard steamer is now in closer proximity to the printer, and its move means that sessions with the digital printer will no longer mean distractions or interruptions in the classes that were often ongoing where the printer was previously located. The addition of a window to the studio door also means that visitors to the department will be able to more easily observe the printer in action. Keep Reading For Digital Textile Printing Studio
Quick Flight to Industry Overview
The European Union has emerged as a one large scale exporter of textile machinery in the international scenario. Some other countable and creditable manufacturers and exporters of textile machinery include Italy, Germany and Spain. In all of them Spain has sprung out as an important manufacturer of textile machinery and has secured its place by the 11th rank world wide. Diversification and innovation played a major role in the retainable position of Spain. About 69 machinery companies gain financial credit worth 245 million Euros in the Spain. This sector evolves 2600 jobs.
Spanish textile machinery industry has flourished with the structure of small and medium sized companies with the strength of less than 50 employees. These companies are still facing very tough competition with the world leaders to achieve the international standards of price, design, quality and service. Weaving machine spare parts, knitting, sewing, accessories and spinning are the different categories included under the textile machinery sector of Spain. 90% of this sector of textile machinery of Spain is occupied by small and medium scale companies which has strength of less than 50 employees.
Now-a-days maximum no. of companies are outsourcing the manufacturers of parts for the workshops designed for special purposes. Some companies have specialization in product research and development and innovations and some have in machine assembly phases.
Technical textile has grown more in the last decade. Major change is seen in “traditional textiles” so changes play major roles in products also like modifying or diversifying products of machinery. The related sectors for this are agriculture, hygiene and medicine, chemicals, packing and packaging and automotive industry.
Research and Development is a Keyword for Growth
Spain is giving special attention on the Research and Development of the textile machinery sector
and has started new centers to give way to new innovation process. Spain’s machinery companies took guidance from these centers to provide most technologically competitive machineries and due to this Spain’s textile machinery are always in demand. The export of machinery in Spain is of 70% of its total production.
The most aimed destination for the Spanish exporters is European Union and it is two third of the total exports of the country. The exports in the countries like Latin America, North America and Middle East is also noteworthy. New destinations like USA, Mexico, France, Turkey and India have new developing markets which are the reasons for the rise in the demand of progress. These destinations are five most targeted destinations for exports of textile machinery in the year 2006.
Geographical Distribution and Production
The good research & Development and innovations lead Spain in the global market in the technical textiles. The investment by this sector is 2.30 billion Euros in research and development projects and 4.60 billion Euros in new facilities and capital goods. The production in different regions of Spain is 3% in Valencia, 64% in Catalonia and 32% in Madrid of total sales. There are only two companies in Madrid though its contribution is of 32%.
Progressive Structural Changes of the Sector
Dyeing and finishing is a very much important sub sector of Spain. This dyeing and finishing sector consists of 32 companies and is the leading sector of country.

Preliminary Remarks
Today, the well-known 3-roller double-apron drafting systems of ring spinning frames permit to draft rovings up to a total draft of 80 and more under optimum conditions. The task of the break-draft zone is to introduce the sliding process of the fibres of the twisted roving. In the subsequent main draft zone, the fibre strand is guided between the top and the bottom aprons and drafted to the desired final count of the yarn.
This mode of operation is already very old and has hardly been modified in the last decades.
With the ACP Quality Package by SUESSEN it is now possible, however, to improve the drafting process in the main draft zone and consequently the values of the most important yarn parameters.
The Drafting Process on the Ring Spinning Machine
2.1 The Break-Draft
The purpose of the break-draft zone is to prepare the main draft. The fibres in the roving are stretched and extended up to a degree which allows them to shift in the main zone immediately after leaving the cradle clamping line.
The basic correlation for each individual staple length between the setting of the break-draft zone and of the break-draft of a ring frame drafting system is shown in Fig. 2.
A long break-draft zone with the smallest possible break-draft must definitely be preferred. It reduces very clearly the wear of top roller cots and aprons and the load on the draft gearing, especially in the case of long machines.
In addition, the total system is less prone to climatic modifications, variations in fibre length and fluctuation in the drafting resistance of the roving.
2.2 The Main Draft
As a basic principle, each of the two pairs of rollers in a drafting zone produces a zone of fibre friction by pressure1. The fibre condensation caused by this pressure does not only have a vertical effect, but spreads from both sides into the fibre strand (Fig. 3).
Both fields of friction are finally responsible for fibre guidance and the extent of regularity produced by the drafting process. The two fields of friction should not overlap, nor should their spheres of activity be too far apart.
It is beneficial to the draft and degree of regularity achievable, if within a drafting zone the field of friction of the back roller pair reaches as far as possible into the drafting zone to guide the fibres as long as possible. The front field of friction should be short and strong so that only the clamped fibres are drawn out of the fibre strand. This ideal is however restricted by relatively close limits in design as a result of the geometrical conditions.

Recently the Indonesian government had announced to ban import of second hand machinery in the country. “This move on the part of the government is to help the domestic machinery industry as well as reduce energy consumption”, Mr Ansari Bukhari, Director General, Ministry of Trade and Industry, had said will announcing the same.Since this decision may affect the textile industry which imports a sizeable amount of textile machinery, fibre2fashion.com spoke to Mr. Ernovian G. Ismy, Secretary General of the Indonesian Textile Association to get his views on the decision of the Ministry of Industry.Mr Ismy said, “In our opinion the policy should be re-investigated since the local textile machinery industry is still unable to fulfill demand of machinery from textile industry and due to the ongoing crisis, some of the textile industry players are facing difficulties in purchasing the more expensive new machines.”Contradicting the decision of the ministry, Mr Ismy added by saying that, “Not all used machines are in-efficient. Actually a few of the used machines are able to work for good periods of time and the biggest stumbling factor is that the textile industry in Indonesia lacks trust and support of the banking and financial agencies to fund purchase of new machineries.” Keep Reading At........
