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. -

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. Keywords: Painted textiles, Ramie fber, Conservation methods, Reinforcement, Cultural relic Introduction Among them, painted ma textiles are characterized by Textiles in all forms are an essential part of human civi- the fexibility, draping quality, heterogeneity, and mul- lization [1]. -
Raffia Palm Fibre, Composite, Ortho Unsaturated Polyester, Alkali Treatment
American Journal of Polymer Science 2014, 4(4): 117-121 DOI: 10.5923/j.ajps.20140404.03 The Effect of Alkali Treatment on the Tensile Behaviour and Hardness of Raffia Palm Fibre Reinforced Composites D. C. Anike1,*, T. U. Onuegbu1, I. M. Ogbu2, I. O. Alaekwe1 1Department of Pure and Industrial Chemistry, Nnamdi Azikiwe University Awka, Anambra State, Nigeria 2Department of Chemistry Federal University Ndufu-Alike, Ikwo Ebonyi State, Nigeria Abstract The effects of alkali treatment and fibre loads on the properties of raffia palm fibre polyester composite were studied. Some clean raffia palm fibres were treated with 10% NaOH, and ground. The ground treated and untreated fibres were incorporated into the ortho unsaturated polyester resin. The treated and the untreated fibre composites samples were subjected to tensile tests according to ASTM D638 using instron model 3369. The microhardness test was done by forcing a diamond cone indenter into the surface of the hard specimen, to create an indentation. The significant findings of the results showed that alkali treatment improved the microhardness and extension at break at all fibre loads, better than the untreated fibre composites, with the highest values at 20% (14.40 and 3.47mm for microhardness and extension at break respectively). Tensile strength, tensile strain and modulus of elasticity also improved for alkali treated fibre composites, except in 5% and 20% for tensile strength, 15% for tensile strain, and 15% and 20% for modulus of elasticity, compared to the corresponding fibre loads of untreated fibre composites.

Installation Guidelines for Livos Wallcovering
Cu& sisalcarperrant.com INSTALLATION GUIDELINES FOR LIVOS WALLCOVERING RECOMMENDED ADHESIVE Use Sisal #1-422 Adhesive (available in 3.5 gallon pail and covers 23 sq/yds). • Sisal is a natural fiber that reacts to excess moisture in other types of wallcovering and multi-purpose adhesive by shrinking before the adhesive dries and sets, which is normally during the first 24 hours after the wallcovering has been applied to the wall. • Sisal #1-422 Adhesive contains fire retardant for passage of the NFPA test method, which is used by national commercial fire codes such as the Uniform Building Code. HUMIDITY LEVELS EFFECT THE DRYING TIME OF THE ADHESIVE Airborne moisture causes the adhesive to dry slowly and may cause the sisal wallcovering to shrink at the seams and edges. Avoid this condition by installing sisal wallcovering in climate control buildings or use mechanical fans at the point of installation to provide air movement. Keeping all doorways to the outside of the building closed is also recommended. ADHESIVE APPLICATION 1. For ease of troweling the low water content #1-422 Sisal Adhesive, apply adhesive to primed new walls or previously painted walls. On walls that have been stripped of old wallcovering, priming the old adhesive is not necessary. 2. Use a 3/16th x 5/32nd V-notched trowel. Check previously used trowels since the notch depth can be scraped flat with use. 3. Spread adhesive over the entire surface. Seal the edges with a clear latex seam sealer. Spots left uncovered with adhesive cause air pockets. 4. A good bond with the wallcovering can only occur when the wallcovering is pressed into the adhesive. -

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).
