Abstract
The invention discloses a polyester-spandex double corn spun yarn which comprises a core yarn and covering fibers; the core yarn is composed of elastic polyester fibers polymerizedby use of polyterephthalic acid and 1,2-propylene glycol alginate, and spandex; the covering fibers are natural fibers or chemical fibers; the weight percentages of the elastic polyester fibers, the spandex and the covering fibers are 3-9%, 2-8% and 84-94%, respectively. Two thick yarns formed from the covering fibers are fed into a flare opening in parallel; the elastic polyester fibers are introduced into a godet wheel by use of a tension adjusting device and the tension value of the elastic polyester fibers is controlled in the range of 28-30CN; the spandex is placed on a godet, pre-drafted by 2.7-3.2 parts, fed into a front roller jaw after being converged with the elastic polyester fibers at the godet wheel, and further converged with the coring fibers and formed into the corn spun yarn under the twisting action of a spinning frame. The double corn spun yarn is prepared by use of the elastic polyester fibers and the spandex so that excellent elasticity of the spandex and the excellent resilience of the polyester fibers are combined, and the formed fabric is comfortable to wear and capable of preserving the shape for a long time.
Description
Technical field
The present invention relates to a kind of cladded yarn, be specifically related to a kind of ammonia double-contracting heart yarn of washing, also relate to the fabric being made into by this double-contracting heart yarn, this belongs to Textile Engineering technical field.
Background technology
Cladded yarn generally take powerful and elastic force all good synthetic fiber filament be core silk, the staple fibres such as outsourcing cotton, hair, viscose are twisted and the yarn that is spun into together.Cladded yarn has the premium properties of long filament heart yarn and outsourcing staple fibre concurrently.More common cladded yarn has polyester-cotton blend cladded yarn, and it take polyester filament as heart yarn, outsourcing cotton fiber.Also have spandex core-spun yarn, it is to take spandex filament as heart yarn, the yarn that other fibers of outsourcing are made.The knitted fabric of being made by this cladded yarn or cowboy's trousering, capable of expansion and contraction while wearing, comfortable fittingness.
Ptt fiber (being commonly called as elasticity terylene) is to be by Shell Chemical(shell chemical company the earliest) new type polyester fiber made by PTA and PDO polymerization, spinning from petroleum technology route and biology corn process route respectively with du pont company.Ptt fiber and PET(polyethylene terephthalate) fiber, PBT(poly terephthalic acid 1.4 butanediol esters) fiber belongs to polyester fiber together.Ptt fiber has the characteristic of terylene, polyamide fibre, acrylic fibers concurrently, except antifouling property well, be easy in addition dyeing, soft, high resilience, extensibility is equally good with spandex fibre, compares be easier to processing with elastomer spandex, is applicable to very much textile garment fabric; PTT also has the features such as dry and comfortable, well-pressed in addition.Compare with spandex fibre, ptt fiber has excellent elongation restorative (extend 20% and still can recover its original length).
Spandex is a kind of elastomer, spandex has deep drawing quality (500%～700%), (200% extends low elastic modulus, 0.04～0.12 gram/dawn) and (200% elongation of high elasticity response rate, 95%～99%), general spandex is not used separately, by making spandex core-spun yarn at other short fibers of spandex filament outsourcing or long filament, the fabric elasticity that spandex core-spun yarn is spun into is good, comfortable and easy to wear, but its elasticity residual rate of fabric and washing shrinkage that elasticity is better also can increase, and the weatherability of spandex fibre and heat resistance poor, fabric is worn for a long time even long storage time and all can be followed the string, produce the phenomenon of lax distortion.
Given this, need to provide the stretch yarn of a kind of elasticity and good stability of the dimension, the long-time spandex core-spun yarn that is difficult for lax deformation of placing, therefore, can consider to utilize the elongation of ptt fiber excellence restorative, improves the easily defect of lax distortion of spandex core-spun yarn.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of brute force high, there is the lasting flexible ammonia double-contracting heart yarn of washing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ammonia double-contracting heart yarn of washing, comprise heart yarn and outer wrapping fiber, and its innovative point is: ptt fiber and the spandex thread of described heart yarn for being formed by poly terephthalic acid and 1,3-PD polyisocyanate polyaddition; Described outer wrapping fiber is natural fabric or chemical fibre; The mass percent of described elasticity polyster fibre, spandex thread and outer wrapping fiber is 4～9%:2～8%:84～94%.
Further, described heart yarn adopts the ptt fiber of 40～82dtex and the spandex thread of 38～46dtex, and washing ammonia double-contracting heart yarn is 16～48tex.
