LAPPEENRANTA UNIVERSITY OF TECHNOLOGY School of Business and Management Master’s Degree Program in Supply Management Master’s Thesis USAGE OF ORGANIC COTTON IN FINNISH TEXTILE INDUSTRY 1st Examiner: Professor Jukka Hallikas 2nd Examiner: Associate Professor Katrina Lintukangas Elina Luukkanen 2017 ABSTRACT Author: Elina Luukkanen Title: Usage of organic cotton in Finnish textile industry Faculty: School of Business and Management Major: Master’s Degree Programme in Supply Management Year: 2017 Master’s thesis: Lappeenranta University of Technology, 86 pages, 23 figures, 10 tables, 3 appendices Examiners: Professor Jukka Hallikas, Associate Professor Katrina Lintukangas Keywords: organic cotton, textile industry, competitive advantage, corporate environmental management The purpose of this thesis is to find out the future direction of organic cotton usage in Finnish textile industry. In addition to that, this research aims to find out the most important reasons why Finnish textile industry companies have chosen to use organic cotton in their cotton products and what is the biggest competitive advantage achieved by using it. The study concentrates on the ecological pillar of sustainability and thus doesn’t consider the social aspects of raw material production. The study was conducted by using quantitative research method by sending surveys for representatives in Finnish textile industry companies which are textile manufacturers, textile wholesalers, textile retailers or other textile industry companies. Growth in organic cotton and other ecological material use is a worldwide phenomenon and the results of the study show, that the same trend continues also in Finland. The most important factors that have affected the choice of using organic cotton are consumers’ growing appreciation for ecological products, creating a better brand image among consumers and better reputation on the market. -
Cotton and the Environment
Cotton and the Environment Approximately 25.137 million metric tons (MT) of cotton were grown globally in 2017/18 on 31.865 million hectares of land in 61 countries. This is equivalent to roughly 2.78% of global arable lanD in 61 countries.1 Following are several reasons why organic cotton proDuction is important to the long-term health of people anD the planet. Cotton’s overall environmental impact • In the U.S., cotton ranks in thirD place in terms of pesticiDe use after only corn anD soybeans. Almost 48 million pounds of pesticides were useD on cotton in 2017.2 • The same year, cotton rankeD fourth in terms of fertilizer use on crops – almost 1.5 billion pounds – behind only corn, soybeans, and wheat.3 • Global cotton proDuction releases 220 million metric tons (MT) of carbon DioxiDe a year, with one MT of non-organic cotton fiber producing 1.8 MT of carbon dioxide.4 • It takes more than 2,700 liters of water to make one conventional cotton t-shirt, anD almost 11,000 to make a pair of jeans.5 • In InDia, home to more cotton farmers than any other country, pesticides applieD to cotton production account for over half of the total amount applied annually despite cotton acreage representing just 5% of all agricultural lanD there.6 Pesticide and fertilizer use on cotton Cotton used $4.2 billion worth of pesticides in 2017 accounting for 6.35% by value of all the plant protection chemicals solD that year, incluDing 12.34% of all insecticiDe sales anD 3.94% of herbiciDe sales. -

Gaud) cultivation industry, the feasibility of a new harvesting mode was investigated. This allows a continuous supply of ramie within a growing season and provided theoretical and technical support for industrialized production of ramie. Huazhu 4 was used and harvesting times were within 28 May to 21 October 7 days interval. Five harvesting modes were designed with 3 replications, with traditional harvesting mode as the control. The results showed that the range in fiber fineness among the five harvesting modes was 1659–1958 m/g. The mean in mode 1 was the highest of the five modes (1958 m/g) and was 6.47% higher than in controls. Compared to controls, the average fiber fineness in mode 5 was 1.96% higher, and that of mode 4 was the same as the controls. However, modes 2 and 3 had 9.79 and 5.55% lower mean fiber fineness compared with controls, respectively. The harvested yields of raw fiber in modes 2 and 3 were 21.50 and 5.04%, respectively higher than controls - with no increases in other modes. -
A New Method for the Conservation of Ancient Colored Paintings on Ramie
Liu et al. Herit Sci (2021) 9:13 https://doi.org/10.1186/s40494-021-00486-4 RESEARCH ARTICLE Open Access A new method for the conservation of ancient colored paintings on ramie textiles Jiaojiao Liu*, Yuhu Li*, Daodao Hu, Huiping Xing, Xiaolian Chao, Jing Cao and Zhihui Jia Abstract Textiles are valuable cultural heritage items that are susceptible to several degradation processes due to their sensi- tive nature, such as the case of ancient ma colored-paintings. Therefore, it is important to take measures to protect the precious ma artifacts. Generally, ″ma″ includes ramie, hemp, fax, oil fax, kenaf, jute, and so on. In this paper, an examination and analysis of a painted ma textile were the frst step in proposing an appropriate conservation treat- ment. Standard fber and light microscopy were used to identify the fber type of the painted ma textile. Moreover, custom-made reinforcement materials and technology were introduced with the principles of compatibility, durabil- ity and reversibility. The properties of tensile strength, aging resistance and color alteration of the new material to be added were studied before and after dry heat aging, wet heat aging and UV light aging. After systematic examina- tion and evaluation of the painted ma textile and reinforcement materials, the optimal conservation treatment was established, and exhibition method was established. Our work presents a new method for the conservation of ancient Chinese painted ramie textiles that would promote the protection of these valuable artifacts.

Organic Cotton Fact Sheet
Organic Cotton Fact Sheet What is organic cotton? Organic cotton is grown using methods and materials that have a low impact on the environment. Organic production systems replenish and maintain soil fertility, expand biologically diverse agriculture, and prohibit the use of synthetic toxic and persistent pesticides and fertilizers, as well as genetically engineered seed. Third- party certification organizations verify that organic producers meet strict federal regulations addressing methods and materials allowed in organic production. Much of the demand for organic cotton currently comes from manufacturers and brands with corporate environmental and social responsibility goals driving them to seek to be responsible stewards. So, too, they are acting in response to consumers increasingly seeking sustainable, chemical-free fiber and finished apparel and home products. How much organic cotton is grown globally? Approximately 222,134 farmers grew 1,101,333 bales of organic cotton in 19 countries on 1,035,210 acres of land in 2018/2019, a 31 percent increase over the previous year and the second largest organic cotton harvest on record. In addition, 137,966 acres of cotton-growing land were in-conversion to organic, helping to meet the increasing demand. Organic cotton makes up aapproximately 0.93 percent of global cotton. Organic cotton was grown in the following 19 countries: India (51%), China (17%), Kyrgyzstan (10%), Turkey (10%), Tajikistan (5%), Tanzania (2%), USA (2%), (Uganda (1%), Greece (.5%), Benin (0.4%), Peru (0.2%), Burkina Faso (0.19%), Pakistan (0.17%), Egypt (0.12%), Ethiopia (0.05%), Brazil (0.04%), Mali (0.03%), Argentina (0.005%), and Thailand (0.003%). -

Received: 3 September 2018; Accepted: 18 September 2018; Published: 3 October 2018 Featured Application: Short-term plant cultivation within containers where anoxia often occurs. Abstract: Plastic agricultural nonwoven films are traditionally used as covering materials, and are prone to cause various ecological problems due to their poor biodegradability. In this paper, a ramie fiber/starch nonwoven film was prepared, and was used as bedding material, that was covered by cultivated soil as opposed to covering it. The biodegradability and porosity characteristics of the film were analyzed, and its effect on oxygen supply to soil was investigated. Results showed that the prepared film had good biodegradability (65.6% after 72 days), and had a loose and porous structure, with the main pore size being in the range of 250–300 µm. After the soil moisture content was reduced to about 44%, the oxygen concentration in the soil that was in close contact with the film, which padded the bottom surface of the plate, rose sharply and then kept stable at 20.1%, whereas soil directly in contact with the plate remained extremely anoxic (0.2%). -

19. Principles of Yarn Requirements for Knitting
19. Principles of Yarn Requirements for Knitting Errol Wood Learning objectives On completion of this lecture you should be able to: • Describe the general methods of forming textile fabrics; • Outline the fibre and yarn requirements for machine knitwear • Describe the steps in manufacturing and preparing yarn for knitting Key terms and concepts Weft knitting, warp knitting, fibres, fibre diameter, worsted system, yarn count, steaming, clearing, winding, lubrication, needle loop, sinker loop, courses, wales, latch needle, bearded needle Introduction Knitting as a method of converting yarn into fabric begins with the bending of the yarn into either weft or warp loops. These loops are then intermeshed with other loops of the same open or closed configuration in either a horizontal or vertical direction. These directions correspond respectively to the two basic forms of knitting technology – weft and warp knitting. In recent decades few sectors of the textile industry have grown as rapidly as the machine knitting industry. Advances in knitting technologies and fibres have led to a diverse range of products on the market, from high quality apparel to industrial textiles. The knitting industry can be divided into four groups – fully fashioned, flat knitting, circular knitting and warp knitting. Within the wool industry both fully fashioned and flat knitting are widely used. Circular knitting is limited to certain markets and warp knitting is seldom used for wool. This lecture covers the fibre and yarn requirements for knitting, and explains the formation of knitted structures. A number of texts are useful as general references for this lecture; (Wignall, 1964), (Gohl and Vilensky, 1985) and (Spencer, 1986). -
