The method of manufacture of wet spun yarn
(57) Abstract:The method can be used to generate awarded pure yarn fabric costume-dress assortment and medical products. The method includes brushing flax fiber with the flexibility of 45 mm, carried out in a thin layer with a mass of handfuls 90 - 100 g, the formation of the tape, alignment tape on the four transitions tape machines, the Rove formation, its ennobling without chlorine-containing oxidizing agents and spinning, which form a yarn linear density of 33.5 - 38 Tex with a coefficient of twist 1,15 - 1,20. The invention provides diversification and improve the spinning properties of nicknaming flax fiber for the production awarded pure yarn linear low planes, allows you to get a cheap thin awarded pure environmentally friendly yarn. 1 C.p. f-crystals, 1 table. The invention relates to the textile industry, in particular to methods generate awarded pure yarn on a ring spinning machines for fabrics costume-dress assortment and medical products.Wet spinning of flax fibers used during the formation of thin yarn of fine elementary the products, marketable. This product is thin awarded pure yarn, with demand in both international and domestic market.For the last time in agriculture introduced nepalease varieties of linen, which turns rough, doskonalenia fiber, low spinning ability. Additive chemical fibers improves the efficiency of processing of nicknaming, coarse linen fibers, but the fibers do not. There is no sodium chlorite for the chemical refining of fiber, which ensures the quality of yarn in the normal course of the process. However, the use of chemical fibers and sodium chlorite is limited by the requirements for environmental friendly products. Currently, domestic combed flax fiber it is possible to produce high yarn linear density quality which does not ensure its competitiveness.A method of obtaining flax yarn on a spinning machine, wet spinning, which consists in moistening Rove by conducting it through a liquid bath, centrifuge Rove and pulling her subsequent twisting into yarn and winding the e limits rovings in addition to the enhanced structural nerovnosti has and proveto the humidity that affects the spinning process, reduces the quality of the yarn.The closest analogue of the invention is a method of manufacture of yarn wet spun from flax fiber with the flexibility of 45 mm, including brushing flax fibers formed in the form of handfuls weighing 110-130 g, to form the tape, alignment tape by adding and pulling the three transitions tape machines, the Rove formation, chemical finishing and subsequent wet spinning ring spinning machine PM-88-C5, in this form the yarn linear density 56-46 Tex with a coefficient of twist 1,0-1,05 ("Spinning flax and chemical fibers". The Handbook, edited by L. B. ADAMS, and L. N. GINSBURG, M., Legprombytizdat, 1991, S. 7, 107, 114, 239-240, 253, 312-314, 321-322).The objective of the invention is to provide a process that ensures the achievement of the technical result consists in the expansion of technological capabilities by expanding the range and improve the spinning properties of nicknaming flax fiber for the production awarded pure yarn linear low densities.This technical result in the way is formirovanie the tape, alignment tape adding and pulling on transitions tape machines, the Rove formation, its finishing and spinning, is achieved by brushing flax fibers are in a thin layer formed in the form of handfuls weighing 90-100 g, alignment tape carry on four transitions, and when the spinning form a yarn linear density of 33.5-38 Tex with a coefficient of twist 1,15-1,20.The elevation of flax fibers are without chlorine-containing oxidants.Developed technology generation awarded pure yarn compared to existing yarns, obtained from discomania flax fiber with the flexibility of 45 mm, has the following advantages. Received awarded pure yarns have a lower linear density 38-33,5 Tex while ensuring high physico-mechanical properties in the normal course of the process.The production of yarn carried out by a wet spinning on a spinning machine PM-88-C5, equipped Odnoralov device controlled hoods.The proposed method is carried out on the following technology.Breaking coarse linen fibre rooms 10, 11, 12 with the flexibility of 45 mm is subjected to brushing on lnochesalnom on tape-mixing unit AC-L, then the tape is smoothed by adding and pulling of the four transitions, the total number of plies above 70000, tape machine LCH-2-H1, LCH - 3-H1, LCH-3-L 1, LCH-4-H1, where extra cleaning of the fiber, increasing its thinness and the alignment length and linear density. From the thus prepared tape form the roving linear low density roving machine of the type P-216-L the Rovings chemically Refine regulated technological mode, subjected to alkaline oxidative cooking, excluding deep chlorine bleaching, or are enzyme elevation and at a wet spinning machine PM-88-75 form a yarn linear density 38-33,5 Tex at odds twist 1,15 - 1,20.By known techniques to get slim awarded pure yarn from flax fiber with the flexibility of 45 mm is impossible. The process of ethnological.Specific examples of the produced yarn and physico-mechanical parameters are shown in table. Examples No. 1 and 2 are given according to the proposed method, an example N 3 prototype, example # 4 according to GOST for comparison and example N 5 prototype with obtaining yarn 33,5 Tex.The process proposed method extends the technological capabilities M, from which you can develop awarded pure yarn linear low density of 33.5 - 38 Tex preserving gastromony indicators in the normal course of the process, which characterizes its increased spinning ability. Under the proposed method it is possible to obtain a thin awarded pure environmentally friendly yarn that can be used to generate tissues costume-dress and underwear range for medical and special purpose.The proposed method allows to produce cheaper products due to the use of cheaper raw materials, as the cost of scutching flax N 12 25% less than the cost of breaking the fiber 16. 1. The way we produce yarn wet spun from flax fiber with the flexibility of not more than 45 mm, including brushing flax fibers to form the tape, alignment tape adding and pulling on transitions tape machines, the Rove formation, its finishing and spinning, characterized in that the brushing of flax fibers are in a thin layer formed in the form of handfuls weight 90 - 100 g, the alignment tape carry on four transitions, and when the spinning form the yarn linearifolia flax fibers are without chlorine-containing oxidants.
FIELD: textile industry, in particular, non-circular weaving equipment, for example, weaving units.
SUBSTANCE: apparatus has shaft disposed between columns and adapted for carrying of rotary lever with rotating pressure roll, and spiral spring. Shaft is immovably fixed between flat columns attached by means of bolt-type protrusions to vertically arranged base. Spiral spring is mounted on shaft and spring ends are fixed on rotary lever and on one of columns. Shaft is made stepped and is equipped with basic end portions terminating in threaded parts. Flat columns have rectangular portions continued with bolt-type protrusions. Column arranged at the side of spring end has cylindrical opening for accommodation of rectilinear end of spring.
