Abstract
Yarn contains flax fibre in quantity of 62 % to 93 % in a form of sheath and braid or braid. Method of obtaining the yarn depends on separation of flax fibre in enzymatic process, treating with emulsion containing cation-active agents and joining flax fibre in a form of sheath and braid or braid with the core during spinning process.
Description
Flax core spun yarn and the method of production of flax core spun yarn.
The subject of the invention is flax core spun yarn and method of production of flax core spun yarn.
The striving to improve usable properties of products led to creation of core spun yarns and to the development of several methods of producing them. They have a core of filament fibres or staple fibres. Polish patent no. 45 687 describes a method of obtaining yarn with a core braided with roving in a form of a flat sliver, shaped so in a drawing of a ring spinning frame. Also known are the solutions from Polish patents 67 331 and 113 689, where core spun yarn is braided with staple fibres whirling in the chamber of an open-end spinning machine. Similar core spun yarn is produced in the device and using the method described by patent RFN DOS 2736 913. In that solution a core is braided with staple fibres not whirling around but being orderly transported and arranged around the core with electrostatic field, aided with suction jets. This solution utilises known phenomenon such as electrostatic field for gathering loose staple fibres around a solid core. Recently there has been a demand for clothing articles with reduced contents of synthetic fibres and introducing natural fibres particularly cotton, wool and - lately - linen.
Commonly known are the spinning blends of flax - polyester, flax - polyacrylonitrile, flax - wool - synthetic fibres. The content of flax in spinning blends is usually below 30%. Also known is a multicomponent yarn, described in patent no. 163517, as well as its production method, where the core constitute fibres with flax contents of 30% to 100% and overall content of flax is up to 35%.
The subject of the invention is flax core spun yarn and the method of producing flax core spun yam. The invented yarn is characterised by containing 62% to 93% of flax fibres in a form of sheath and braid or in a braid form. The core spun yam contains a sheath and braid of 70% to 100% flax fibres or braid of 70% to 100% flax fibres. The method of producing flax core spun yam depends on repeatedly splitting flax fibres into loosely tied elementary fibres, arranging them in parallel and softening, applying flax fibres sheath and braid and carrying out spinning the usual way.
The flax fibre is subjected to enzymatic treatment, according to the method described in patent no P-317584 or to bleaching or dying, then to drying.
As a result of these processes soft modified flax fibre is obtained, with a smooth surface and flexible. Subsequently the modified flax fibre is treated with emulsion containing cation-active agents in volume of 0.5% to 1% of yam mass and then left to allow unifom spreading. Technological process includes subjecting flax fibre to known operations such as carding and producing sliver of linear density 2.5ktex to 15ktex. Spinning occurs in the usual way. In the invented process of producing core spun yam one can utilise raw flax fibres, which are by-product or recycled.
Core spun yarn produced as per invention is soft and its products are stable in shape and shape well.
Detailed description of the invention can be found in the examples.
Example 1. Noils of flax fibre of linear density 2.2tex and average length 178.5mm are subjected to enzymatic treatment in active pectolitic bath of 1000PM and temperature 70°C for 60 minutes. Next in hot alkaline bath of pH = 10 for 30min. After that they are subjected to rinsing until pH drops to 6, avivaging and drying. Then the fibre is opened, mixed and treated with water-based emulsion, containing 0.5% cation active agent (calculated to overall fibre volume) and left in mixing line to cause an uniform and even spreading. Next the flax fibre is carded and formed in a sliver of linear density 3.0ktex. The length of the flax fibre after processing is 25mm to 38mm and linear density 0.5tex to l.Otex. Spinning is carried out the usual way, using a filament yam with linear density lOOdtex as a core, thinned flax sliver as a sheath and braided with loose flax fibres. As a result of spinning a flax core spun yarn is obtained of
linear density l lOtex and containing 90.7% of modified flax fibre and 9.3% polyamide fibre.
Example 2.
Flax fibre is being modified and carded as in Example 1 and spun the usual way with a core made of cotton staple yam with linear density 15 x 2tex, sheath of sliver and braid made of flax fibres. As a result of spinning, flax core spun yam is obtained, of linear density lOOtex being a blend of 70% flax fibres and 30% cotton fibres. Example 3. Flax fibre is modified and treated as in Example 1 to produce a sliver of 100% flax fibres and linear density 3.5ktex. Simultaneously flax fibre is being modified as in Example 1, treated with water-based emulsion containing 1% cation-active agent (calculated to overall fibre volume), mixed with cotton fibre and left to allow an uniform spreading. Next sliver is formed containing 70% flax fibre and 30% cotton fibre, of linear density 3.5ktex. The spinning process is carried out the usual way using a core of cotton yam of linear density 15 x 2tex, sheath in a form of thinned sliver containing 70% flax fibre and 30% cotton fibre and braid containing 100% flax fibre. As a result a core spun yam is produced with 62.3% flax fibre, 37.7% cotton fibre and linear density 125tex. Example 4. Flax fibre is being modified and carded as in Example 1 and spun the usual way. The core is made of staple yam of linear density 20tex, containing 67% polyester fibre and 33% cotton fibre. The sheath contains 100% flax fibres. As a result of spinning a core spun yam is obtained of linear density 135tex, containing 85% flax fibre, 5% cotton fibre and 10% polyester fibre. Example 5.
Noils of flax fibres of 3.2tex linear density and average length 230.9mm are subjected to enzymatic treatment as shown in Example 1. After drying phase flax fibre is opened and mixed and simultaneously treated with water-based emulsion, containing 0.5% cation-active agent (calculated to overall fibre volume) and left to spread uniformly. Next flax fibre is carded and shaped to form sliver of linear density 13.0ktex. The spinning process is carried out the usual way, using a core in a form of polyester filament yarn of linear density l lOdtex and braid of flax fibres. In the spinning process flax core spun yam is produced of linear density 150tex and containing 92.7% odified flax fibre and 7.3% polyester fibre.
