Description
Technical field
The present invention relates to a kind of elastic fabric.
Background technology
Polybutylene terephthalate (PBT) (PBT) fiber is a kind of novel remodeling polyester fiber.Caused people's attention the earliest as a kind of engineering material of function admirable.Along with the development of fibre in differentiation, characteristics such as PBT fiber excellent elasticity more and more are subjected to attracting attention of people in recent years.But at present because Fabric Design, back arrangement processing increases bullet to fiber, the influence of Fabric Style also lacks clear and definite analysis, technology is also imperfect, make general fabrics design and the PBT fabric that processes spring rate bad (below 15%) to occur, DIMENSIONAL STABILITY relatively poor (dry-hot shrinkage is ± 4～± 5%, and boiling water shrinkage is ± 4～± 5%), or defective such as the fabric face out-of-flatness is wrinkling.Limited of the development of PBT fiber at field of textiles.In order to break this situation, this just makes that the analysis and research of PBT Fabric Design and rear processing finishing technology are imperative.
Summary of the invention
The object of the present invention is to provide a kind of have favorable elasticity rate and DIMENSIONAL STABILITY, surfacing, the elastic fabric of soft polybutylene terephthalate (PBT) fiber.
Technical solution of the present invention is
A kind of elastic fabric of polybutylene terephthalate (PBT) fiber is characterized in that: at least a in the warp thread of composition fabric or the weft yarn is the mixed fiber yarn of polybutylene terephthalate false-twisted yarn or polybutylene terephthalate false-twisted yarn and other fiber.
The spring rate of fabric is 15%～60%, elastic recovery rate more than 80% and 160 dry-hot shrinkages when spending in+1.0%～-3.0%, boiling water shrinkage is in+1.0%～-2.5%.
The polybutylene terephthalate fiber content accounts for 20%～100% of total fabric weight.
The tightness of fabric is 700-2000.
The filament number of polybutylene terephthalate fiber is 0.5～5.6dtex.
The interlacing number of weft yarn is 0～80/meter, and the interlacing number of warp thread is 50～120/meter.
The selection that below divides yarn, Fabric Design, arrangement processing 3 aspects, back are described in detail:
1. the selection of yarn
1) among the present invention, the filament number of the PBT fiber of use is thick more, and feel is hard more.So adopting the fiber number of monofilament is 0.5～5.6dtex, to obtain soft hand feeling.Because filament mutual extrusion when getting over the multi-fibre contraction with the filament radical of fiber number yarn, make the minimizing of shrink space, so thereby influence being chosen in when considering feel of spring rate filament radical of yarn and fabric, because of adopt few filament radical as far as possible.Example: 50D-12f-PBTDTY, 75D-24f-PBTDTY etc.
2) intensity of yarn considers that to the requirement of yarn strength the intensity of yarn is in 2.0～5.0cN/dtex scope from road, back process such as weaving, and degree of stretching is 30%～60%.
3) the interlacing number of yarn is few more, and the obstruction that yarn is subjected to when shrinking is also more little, is guaranteeing to adopt the less yarn of interlacing under the normal woven prerequisite so the elasticity of yarn and fabric is also just big more as far as possible.Example: weft yarn time spent interlacing number is 0～80/meter, and the warp thread time spent is 50～120/meter.
2. Fabric Design
1) the present invention can select to carry out weaving through bullet, latitude bullet or longitude and latitude elastic fabric according to purpose.Make the mixed fiber yarn that when elastic fabric warp thread uses PBT false-twisted yarn or false-twisted yarn and other fiber, weft yarn is PET, cotton or other yarn.Weft yarn uses the mixed fiber yarn of PBT false-twisted yarn or false-twisted yarn and other fiber when making the latitude elastic fabric, and weft yarn is PET, cotton or other yarn.Make the four sides when playing longitude and latitude all use the mixed fiber yarn of PBT false-twisted yarn or false-twisted yarn and other fiber.PBT false-twisted yarn or false-twisted yarn and other fiber mix fine or interweave, and be cost-saved on the one hand, can incorporate the advantage of another yarn on the other hand again.
2) the PBT fiber content accounts for 20%～100% of fabric weight among the present invention, considers the performance of the characteristic of PBT, and better content is 50～100%.Content can make the elasticity of fabric and feel be brought into play fully in above-mentioned scope.
3) tissue of fabric can adopt plain weave among the present invention, twill, satin weave or its alternative construction.Heavily flat as 2/2 latitude, 2/1 twill, 2/2 twill, 5 pieces of satin weaves etc.Its middle twill compares with plain weave because relative minimizing of the degree of crook of yarn in fabric (reducing through weft yarn cross-point number in the unit are), the obstruction power when yarn shrinks in the fabric that makes reduces, the free movable ability of yarn strengthens, thereby make the contractility grow of fabric, through after processing back be difficult to produce under the prerequisite of wrinkle and forming high elastic fabric, be preferred tissue.
4) the present invention is in order to obtain 15%～60% spring rate, the tightness of fabric is 700～2000, best warp-wise tightness is 900～1200 when making with the heavy plain weave of 2/2 latitude as 50D/12f warp thread and 75D/24f weft yarn, best broadwise tightness is 700～950, in this scope fabric face do not crease easily and DIMENSIONAL STABILITY good.
5) though of the present invention to weave loom available jet, water spray, looms such as arrow shaft are weaved, but consider the wefting insertion of avoiding under the high-tension that allows the elasticity of weft yarn fully play and the generation that reduces broadwise spring rate difference, so jet, the water jet looms weaving less when selecting wefting insertion to the yarn active force.
3. back arrangement processing
Back arrangement of the present invention can comprise following content: concise, and middle typing, dyeing resin, finished product typing.Can implement bleaching according to the concrete condition of the blending and the object fiber that interweaves in addition, singe operations such as decrement.
1) temperature is 60～100 ℃ during refining, adopts heat alkali liquid, and it is dirty that soaping agent (soaping agent is a non-cationic type surfactant, routine GQ008) is removed when weaving slurry on the yarn and greasy dirt etc.Because fabric is refining under the liquid of higher temperature, yarn has been removed the influence of tension force, and contraction to a certain degree is to the increase of fabric elasticity rate and obtain not having the smooth surface of wrinkle and play a role.
2) the middle typing before the dyeing also is in order to guarantee the smooth surface of fabric on the one hand, be unlikely to fierce the contraction when making dyeing and produce wrinkle, and dry-hot shrinkage is in+1.0%～-3.0% when guaranteeing 160 ℃, and boiling water shrinkage plays main effect+1.0%～-2.5% with interior.Treatment temperature is 140～180 ℃, and the interior constancy of this temperature range is good and kept curling of false twist yarn can the elasticity of fabric not to be caused damage.Though the above HEAT SETTING effect of temperature 180 degree can increase but the feel hardening to some extent, the phenomenon of loss of elasticity is comparatively serious.Along with on dye the prolongation dyestuff of time the fiber dye-uptake presented the downward trend again that raises earlier.The HEAT SETTING processing time is when scope was interior in 40～70 seconds, to make dye molecule reach the highest to the fiber dye-uptake.
3) owing to compared among the PBT two methyl many with PET, make intermolecular cohesiveness reduce, when relatively low dyeing temperature, just can obtain PET fiber resulting Color under high-temperature and high-pressure conditions, according to the mixed fibre situation dyeing treatment conditions that interweave is 120～135 ℃, and the time is 20～50 minutes.
4) can use during resin finishing antistatic additive (CATION or anionic antistatic agent, routine DEATRON) and softener (silicon system or non-silicon anionic softener are as TF438) to adjust the feel of fabric.
5) the finished product setting temperature is 150～180 ℃, and the time is 40～70 seconds.
The present invention have general fabrics design and back arrangement processing incomparable advantage: have the excellent elasticity rate, elastic recovery rate and good DIMENSIONAL STABILITY, surfacing, characteristics such as soft.The lines that can fully represent the human body grace when wearing strengthen the elongation amplitude of people when moving widely, reduce friction and stimulation with skin.
