Water and oil repellent finishing is done on cotton fabric by pad-dry baking process. The influences of baking temperature, baking time, pH value and concentration of finishing liquid on water and oil contact angle of fabric are analyzed. The result shows that the optimized water/oil repellent finishing process of cotton fabrics is as follows: The concentration of finishing agent is 30 g/L, pH value is 6.67, pick up rate is 80%, and the baking time is 8 minutes under 140. After finishing, the oil and water contact angle of the cotton fabrics can reach up to 143.33 degrees and 134 degrees respectively and at this time the finishing effect is the best. Scanning Electron Microscopy (SEM) reveals that after water and oil repellent finishing, the surface of the cotton fiber becomes smooth, the finishing agent has good film-forming ability and it has better water and oil repellent performance.

From ancient times India is known as the land of opportunities and the abundant amount of natural resources one of the major reason behind this opportunities. The agriculture and handloom industry remain mean as dominant employment sectors from long time and even in the age of industrialization they retain their positions has major employment providing sectors successfully, the excessive attraction towards the industrialisation and technology are considered as major threats to the handloom industry. The handloom industry have the potential providing the employment to over 13 million weavers and this factor makes it as largest cottage industry in the country, simultaneously the employment provided by it is second largest economic activity next to agriculture. The importance given to power loom industry is creating handsome of problems in the handloom industry and it's survival in this modern era is a major question because of large number of issues it is facing such as hike in the yarn prices, lack of proper infrastructure, treating as secondary source next to power loom and many others. In India, the Guntur district, which is once known as hub of Handloom industry, is now facing the problem of lack of raw materials, marketing problem and many others, a lot of research have been carried out over the years to find out an appropriate solution to protect the handloom industry and give hope to the weavers for its survival. This article highlights the importance of handloom industry in terms of employment as well as the root-cause analysis for finding the major issues related to it which helps to regain its lost glory.

Jute as very unique natural bast and its industrial manufacturing started in India from around 1855. Till then jute processing machinery and the processing system progressed very slowly. Presently jute fibre/yarn used in several diversified products other than food grain packaging bag. To improve the quality of jute yarn a study has been carried out in a jute mill where the quality of jute yarn produced by usual finisher card (fitted with roll former) is compared with quality of yarn produced by the draw head fitted finisher card system. As two types of draw head systems are available presently, total three process are compared based on yarn quality produced by them. It is found that draw head plays an important role on jute yarn quality in comparison to simple finisher card with roll former system. Specially the yarn produced by L make draw head system shows uniform controlled average sliver weight, lower sliver and yarn CV% better evenness and higher minimum yarn strength in yarn. Traditional drawing frames are used for regular jute yarn, now-a-days by using draw heads in jute mills will improve the quality of the output sliver. This sliver is producing regular and fine jute yarn with higher tensile strength, work of rupture, breaking elongation and quality ratio and count variation percentage. The produced modified yarn was also more regular and uniform comparing to the traditional drawing frame.

In the twenty-first century, product making has evolving widely in all such field of engineering and technology. Textiles are not lagging on the marathon of such development and making. Smart textiles are the exciting innovation in the field of textiles and clothing. It can sense and analyze the signals and responds in a perfect way and the response which was being made can be electrical, thermal, mechanical, chemical, magnetic or from other source. The extent of smartness can be divided into three subgroups such as passive smart textiles, active smart textiles, and very smart textiles. Now it is not just seen in the Hollywood movies, it is not only limited in our world of fantasy, but also it comes in our day-to-day life with at most perfect possibility. It is now commonly used in numbers of fields. So, it can also be called the next generation clothing. This review aims to show the story of smart textiles, its types and functions. Present smart textiles products and their applications as well as market overview of smart textiles have also been discussed.

This article is based on the theoretical justification for the development of energy saving projects and the main operating parameters for the implementation of the process of preparing high-density cotton seeds for storage. One of the issues of the program of economic development of the Republic of Uzbekistan is to increase the productivity of high-quality fiber and its implementation on the world market. The production of high-quality raw cotton fiber depends on the fact that the production process is organized on the basis of technical requirements. In particular, in the process of drying cotton in processing plants, it is important to reduce its moisture content and storage.

Squarylium dyes are organic dyes of intense flouresence properties typically in the red to near-infrared region obtained from squaric acid. Squarylium dyes were synthSquarylium dyes are organic dyes of intense flouresence properties typically in the red to near-infrared region obtained from squaric acid. Squarylium dyes were synthesized from aminothiophene which are low molecular weight compound with good electron donating properties. The molecular weight of the dyes ranges from 276 g/mol-434 g/mol with melting point of spanning from 314 °C–336 °C. The FT-IR of band of the squarylium dyes showed sharp absorption bands of 3224.1-3649.1 cm-1 corresponding to the N-H stretch functional group present in the molecule, the C=O group was seen between 1640.0 cm-1-1796.6 cm-1 and the N=C=S (isothiocyanate) functional group ranged from 2105.9 cm-1-2206.6 cm-1. The electrical conductivity measurements were obtained by employing a standard process using a programmable LCR meter at a frequency range of 200 hz-100000 hz and the result calculated using the formular σ =L/RA. The electrical conductivity of synthesized dyes were observed to be within the range of 10-5-10-8 Sm-1. The electrical conductivity of the dyes and aminothiophene substituted squarylium dyes lies within the range of electrical conductivity for semiconductor which is between 10-12 -10-2 Sm-1.

Bast fibre dyeing process was common practice as the value addition of most bast fibres was demanded for various commercial and household
applications. In this research work, kusha fibre (which was extracted in our previous work) subjected to dyeing using direct, reactive, vat
and cationic dyes for the first time. The dyeing process was performed using concentrations 0.5%, 1%& 3% (W/W) dye to fibre with MLR
1:20. After dyeing process; performance of dyed fibre (dye absorbency measurement, colourfastness to washing, colourfastness to
rubbing, colourfastness to light) and tensile tests were conducted. The results revealed that; K/S value of all dyed kusha fibre
samples increases as the concentration of dyes applied increases, the colourfastness to washing of dyed fibres except the of direct
dyes were found good, in both dry and wet rubbing fastness, reactive dyed samples have overall good rubbing fatness performance over the
others, light fastness result shows it is good performance for all samples according to blue wool light fastness standard that exceeds 6. The
tensile strength and elongation of dyed samples showed slight decrement in both vat and direct dyed samples; whereas, the considerable
decrement was observed both in samples dyed with reactive and basic dyes as there is formation of covalent bond between fibre and dye
and acid medium of processing affected the tensile property respectively.
