Wojska Polskiego 71 b, 60-630 Poznań, Poland This paper contains a review of basic research and new concepts in flax and hemp fibre processing for flax and hemp cotton-like and wool-like yarns spun by different spinning systems. The review covers the trends and economical conditions since the beginning of the 20th century. We present the advantages and disadvantages of flax and hemp as raw materials for the production of cottonised fibres from the agricultural and economical point of view. Some significant morphological differences between flax and hemp are highlighted regarding the applicability of these fibres to the cottonisation process and spinning in blends with cotton by the pneumatic-mechanical spinning system. The content of mechanically obtained flax and hemp cottonised fibres in blends with cotton and the range of linear density of yarns is discussed. Examples of blended yarns with flax and hemp cottonised fibres applied in ready-made products are also presented.

In this study, we have compared the properties of composite materials made of scutched flax and flax tows from the same batch. A series of unidirectional epoxy composites were manufactured by wet moulding. Mechanical properties of single fibers and composite materials were measured by tensile tests. The tensile properties of single fibers were in the same range. The tensile properties of the unidirectional composites show a similar evolution of properties versus fiber volume fraction. The results show that tows could be used to reinforce high performance composite materials. 1. Introduction A wide range of plant fibers have been studied for composite reinforcement including hemp, jute, sisal and flax [1]. Among them, flax fibers have excellent specific mechanical properties and are being evaluated as a replacement for E-glass fibers [2,3]. Flax (Linum usitatissimum) is the major plant fiber cultivated in northern Europe, mainly for the textile sector. The structure and composition of flax plants is complex [4,5]. The stems contain fiber bundles embedded in cortex tissues at the periphery. In these bundles, single fibers are grouped together by middle lamellae.

  • Agricultural Products FLAX Linum Usitatissimum from Which Comes
    Agricultural Products FLAX Linum usitatissimum from which comes our words “linen”, “linseed oil”, “linoleum”. Flax seed is sewn as early in the springtime as the ground will permit; as soon as the frost leaves it, in other words. The seed was distributed rather densely so that the plants would be forced to grow straight upward to get enough sunlight, rather than to put out branches, which was not desirable. When ready for harvesting, the plants would be about two feet high. When the mature plants were ready for harvesting along about mid-summer, they were pulled up out of the ground rather than cut, and allowed to dry on the surface for a day or two. Cutting caused the plant’s sap to flow out, and this would stain the fibers, after which no amount of bleaching would produce white cloth. After drying, the flax was pulled through a ripple comb made with coarse wooden or heavy wire teeth. This broke off the pods and the seeds, which were saved for next year’s planting, or for barter or cash sale. The stalks were then tied by the top end in bundles called “beats”, or “bates” (depending on what part of the country you came from) and the base of the stalks were spread out to form a tent-shaped stack called a “stook” for drying. Next came soaking in water for fermentation, the length of time depending on the temperature and whether the water was moving. One method was to put the stalks in a stream. This was a smelly and slow process.

But it’s not the only option available nowadays. We can spin fiber produced from other animals, from plants, or from manufacturing processes. Bam- boo, soy, and corn can all be made into yarn. So can wood pulp and seaweed: if you’ve never heard of Seacell, Modal, or Lyocell, read on. Do all of these spinnable fibers qualify as natural? Are they vegan (i.e., animal-friendly) or at least animal- neutral? How sustainable are the different production methods? It depends on your personal definitions and choices. Some people might see rayon, extruded from wood pulp, as too far removed from Nature, while others might prefer rayon to water-intensive hemp retting. You’ll read about protein and cellulose fibers in the first article, then find others on plant-based fibers, either directly from the plant or processed in some way. If you want to spin something other than wool, you can find the perfect substitute here.

  • Notes from the Flax Presentation by Bruce Engebertson April 29, 2017
    notes from the Flax Presentation by Bruce Engebertson April 29, 2017 Bruce began spinning wool at age 10, despite the fact that no one in his immediate family had any background in spinning. A chance referral led him to Ester Kromaki about 25 years ago, and she taught him the traditional Finnish techniques for growing, processing, spinning, and weaving flax. He says his linen knowledge is firmly based in the Finnish traditions and that "he doesn't know a variety of methods but the ones he knows, he knows well." The flax plant is an annual that dies in the winter. It is a "greedy" plant which will take lots of nutrients, so it's best not to plant it in soil that has been exhausted by other crops like corn. Flax is best in full sun and protected from the wind. It is relatively free from insect pests and will even keep potato bugs away (so plant near potatoes!). Prepare the seed bed by spading up the area to be seeded (in our case, approximately 3 ft by 3 ft) and adding in some cow manure or other fertilizer. Make sure the area is free of weeds when you seed. Seed flax when the lilacs just begin blooming. The seed should be spread thickly -- about 5 to 7 seeds for a thumbprint (of course, this depends on the size of your -- hopefully green -- thumb). Do not plant in rows. Divide the seeds in half and sow half in one direction and the other half if the other direction. If the soil is the same color as the seeds, you can add sand to the mix so you'll have an idea of how the seeds are being spread out.

In this present study, a set of flax/polypropylene (PP) micro-braided and co-wrapped yarns was developed by varying different PP parameters (PP braiding angles and PP wrapping turns, respectively) to get different flax/PP mass ratios. The effects on textile and mechanical characteristics were studied thoroughly at the yarn scale, both dry- and thermo-state tensile tests were carried out, and tensile properties were compared before and after the braiding process to study the braidabilities. It was observed that PP braiding angles of micro-braided yarn influenced the frictional damage on surface treatment agent of flax roving, the cohesive effect between PP filaments/flax roving, and the PP cover factor; PP wrapping turns of co-wrapped yarn had a strong impact on the flax roving damage and the PP coverage, which further influenced the characteristics.

  • Textile Yarns
    TEXTILE YARNS 1970 40 2010 Years of Progress ® ® Printed on Re-Cycled Paper Save a tree. 1 Textile Yarns 1.0 Introduction A textile yarn is a continuous strand of staple or filament fibers arranged in a form suitable for weaving, knitting, or other form of fabric assembly. Also, a yarn is a textile product of substantial length and relatively small cross-section consisting of fibers with twist and/or filaments without twist. The yarn can be twisted with one or more yarns to create added value or aesthetics. Traditionally, yarns have been constructed of fibers of finite length called staple fibers. Today, continuous filament yarns are also used to construct yarns. Filament yarns tend to be smoother, more lustrous, more uniform, harsher, and less absorbent. Spun yarns have a hairy surface, are more uneven in appearance, have lower luster, are softer, and more absorbent. Spun yarn is the yarn of choice in many woven and knitted fabric products. The short fibers can be natural fibers such as cotton where the fiber grows in short lengths. But they can also be synthetic fibers such as polyester that are manufactured in a continuous length and then cut into shorter staple lengths. This document will discuss how yarns are formed. It covers fiber preparation and spinning for cotton and blends of cotton. Also covered is the production of synthetic filaments and their conversion to tow and how the tow in turn gets cut into short fibers. Then the steps in the processing of cotton and cotton/synthetic blended spun yarns and the various spinning systems used will be addressed.

  • Prairie Clothes: Woman’S World
    1 Prairie Clothes: Woman’s World By William R. Harshbarger Arcola, Illinois December 2017 2 Prologue Pioneers knew how to survive. In our time, we cannot know the nuances of prairie life, or fully appreciate the effort and time that our ancestors spent on the basic skills necessary to get through the day. For the most part, the work was exhausting and demanding. Fortunately, the power of community undergirded their survival, assuring each family of support in time of need. The indelible frontier experience created a sense of equality and liberation from the constraints of bias and social etiquette. Pioneers valued each other. They measured a person’s worth by the standard of honesty, skill, and the contribution made to the community. The prairie experience changed the settlers. Eliza W. Farnham came to Illinois in 1836, stayed about five years, married, and returned to New York. In 1846, she fondly recalled the experience in her book, Life in Prairie Land. She explained how people were struck by the breath-taking beauty of the prairie—the grasses, the birds, springing flowers, and the motion of the wind through the expanse of land. And she foresaw, and was elevated by, a vision of the “glory and greatness” that would develop there. She wrote: “It is the enjoyment afforded by this kind of emancipation which so endears the Western country to those who have resided in it. It steals upon the heart like what it is, the very witchery of nature; so that those who are susceptible to it, feel the charm but not the inconvenience through which it is invoked.

By doing this they will gain an understanding of the time involved in the hand manufacture of textiles, and why the people of that time were so thrifty. Instead of discarding scraps of cloth, they used the scraps to make quilts, rag rugs, or to patch holes in garments. Instead of discarding worn garments, they often cut out the most worn parts of a garment and remade it to fit a smaller person. Quilts were often stuffed with old blankets or tattered quilts. B. Students should learn that textile production at Sutter's Fort was not state of the art for the 1840’s.
