Executive summary 

The international Buyers or clients are looking for those countries for producing their apparel products where different types of mills establish as a one stop source for the global apparel market, satisfy and meet customer’s expectation by developing and providing products and services on time, which offer value in terms of Quality, Price, Safety & Environmental impact. And also assure complete compliance with the international quality standards and also to provide the employees internationally acceptable working condition/standards. Bangladesh is one of the best countries for producing textile & apparel product. At this time Bangladesh can challenge with any country for producing apparel product with best quality.  Many countries try to produce good apparel products with best quality and price. So, now-a-days this field becomes very competitive. Bangladesh earns 76% foreign currency from the textile sector. Now-a-days buyer wants 100% quality product. For this reason it is very important to know about the latest technologies in textile sector. To produce a quality product, as a textile engineer I must have a vast knowledge about the production parameters & how to produce a high quality product. To accommodate the theoretical study with technical and practical things industrial training is very important. In my training period, I specially observed that Dacca Dyeing & MFG.CO. Ltd. Produce high quality fabric and fulfill the special requirements from the different types of buyers from following different internationally recommended standard method. In my training period I have learned many things such as different types of machines and their functions, techniques of productions and the management system and Dyeing and printing. So I think this industrial training will help me in future.

 11.1 MARKETING STRATEGIES 2006:

The vision for the year 2006 & beyond is of innovation, speed & service driven marketing where by customers faith & Dacca Dyeing’s capabilities are enhanced in a financially beneficial way. IEKA,LITTLEWOOD,JOTEX,JYSK among other is a good example of this strategy as their volume have grown & promised to go further. We are trying to add new customer tour customer profile. Targeting on new customers we participated on different trade fairs all over the world. Through aggressive & dynamic marketing strategies we established ourselves for 2007 as creative, innovative & reliable supplier in this industry. Our strategy to market mostly value added product was also successful. The year 2006 was the most successful year in terms of sales volume & turn over.

11.2 MARKETING STRATEGIES 2005:

Our marketing team remained at forefront of tackling competitive challenges by exploring new territories, customers & products. In the generally prevailing uncertainties & impending liberalization of quota regimes the design team again played a pivotal role in changing the perception of DACCA DYEING as a typically Asian supplier with increased customer contacts, collaborative working methods new value added products like stretch fabric & slub fabric. New finishes such as Wrinkle free, Teflon & combinations of both were added to our range. Our participation in high profile trade fairs such as Tex world in Paris, France & Magic in Las Vegas, USA increased our visibility in the international market & enhanced our reputation. Next, the fastest growing clothing retailer in the UK gave us additional support to our customer list. There was an exponential growth in sales to H&M. IN spite of the difficult conditions; we were able to penetrate new markets in the form of LEVIS Europe & Mexico. Our overall marketing policy of going for quality rather than volumes paid rich dividends & we were able to not only hold onto our existing customer base but venture into new markets.

11.3 MARKETING STRATEGIES 2004:

The declining retail sales & the losses shown by the big retailers worldwide & the consequent drop in order in the worldwide garment industry provide to be a major challenge to our marketing efforts & strategy. The very fact that in spite of the factors mentioned earlier we maintained more or less the sales of last year, showing a fall on only 3.32% is a credit to our marketing.

 In an uncertain world market, we doubled our efforts with our designed team leading the way. We increased our call on the customers & looked for ways to add new ones also. Having established a strong relationship with LEVIS USA & becoming one of their core suppliers, we targeted Levis Europe & Levis Australia also & made in roads there. Next, who we had brought in last year increased their sales with us substantially as did ZARA. Our other customers are loyal to us, in spite of cutting their sales with other. We added new & dynamic designers to the existing team, & can proudly say that our spring & autumn collections were held as some of the best to be presented. These meetings boosted the confidence of existing buyers & attracted new customer. We again participated in Tex world Fair in Paris & our stall was one of the busiest & most visited one in the whole fair.

We continued with our strategy to market value added products like yarn dyed & fabrics with special finishes. This is reflected in the increase in our average price per linear meter.

We are now in a strong position to take on the challenge of WTO in the end of 2004 when quotas will be abolished & only those company’s with a reputation for innovation, creativity & reliability & the ones having strong strategic relationship & business alliance will survive & benefit.

12.0 Conclusion:

Dacca Dyeing Ltd is a private limited company with composite dyeing manufacturer & exporter and BTL. Customer satisfaction is our main goal, competitive professional service, and price, world class quality, on time delivery, honesty and reliability. They want to maximize synergistic benefit, and become a market leader through the pursuit of high productivity, advanced technological innovation and absolute customer satisfaction by leveraging on the strengths of their core business. They focus on customer needs and wants continuously and manufacture high standard quality dyeing apparels.  They establish themselves as the leading provider of dyeing apparels by serving international market especially for retailer. They strive to meet challenging market needs through a closer working relationship with business partners, innovative manufacturing process and maintaining standard customer service. For achieving their goal, Dacca dyeing manufacturing company limitted has recruited a high profiled human resource team. The production is controlled by technical persons. All of the decision makers of production sector in Dacca Dyeing Ltd. are textiles graduates. According to their capacity they have an enriched production team which is very rare in other factories of Bangladesh. The working environment of Dacca Dyeing Ltd. is very good & friendly.  They try to follow al the industrial rules. The management of the Dacca Dyeing ltd is always careful about the satisfaction of the employees. All of the executives & employees of Dacca Dyeing Ltd. are very much cordial & they always appreciate with the learners.

Dacca Dyeing Ltd. wants to get high production & to maintain the quality of the product at a minimum cost. They buy yarn from the different types of spinning mills. There is no yarn testing machine for test yarn. So, sometime they found different types of yarn fault which effect on their production. There is no polar fleece & auto stripe m/c in Dacca Dyeing Ltd. so they are not able to produce all types of dye structure. In dyeing lab Dacca Dyeing Ltd. is using normal pipetting system which can not give the accurate result, but if they use digital pipettting system or dispense type digital pipetting system I think their accuracy will increase to a maximum level. There is no person to input the self shade of different types of lot everyday in the spectrophotometer but for accuracy of the recipe it is very important to input the self shade of different lot of dyes in a regular basis. For dyeing they are using Acme m/c but if they use Fongs, Thies or Sclabos m/c I think their product quality will be higher, because high quality machine gives high production with low liquor ratio with lower amount of chemical.  In garments section, for cutting they usually use manual straight knife cutting m/c and band knife cutting machine, but if they use computerized cutting m/c their accuracy will increase & their efficiency will increase to a maximum leve. If they use embroider and printing machine in their garments, I think, their production will be very high. I think if they improve the above things, their product quality,  efficiency and  accuracy will be increased and  maximum.

12.1 Some Suggestions:

• During the transport of the fabric in the dyeing floor and also during the loading of the m/c, fabrics are soiled for the contact with floor. This makes the fabric/part of the fabric dirty. It may require more scouring/bleaching agent or may create stain making it faulty.
• The dyeing floor is watery most of the time: it should be cleaned all the time.
• The illumination of the dyeing shade should be enhanced. It may exert the worker fatigue ness.
• More skilled labour should be used in a project as BTL. Many time the dosing pipelines are clogged due to the careless dosing of chemicals.
• The m/c stoppage time should be analyzed and minimized. The maintenance should be carried out when the m/c is out of action (wherever possible)
