One adds elater and processing method thereof and purposesTechnical field
The present invention relates to and a kind of novel add elater, be related specifically to a kind of elater that adds with refrigerant sense, and this production method adding elater and purposes。
Background technology
Along with social progress, the mankind are increasing to the demand of clothing, ornaments and other fabric article, and the requirement of fabric property is also become varied。There is substantial amounts of demand to having necessarily functional and that feel is special fabric in the market。Such as have fire-retardant, antistatic, uvioresistant, antibacterial, cooling ventilating fabric deeply by the concern of numerous clients。The property that product made by its fabric has with self, applies to different places and all kinds of crowd being engaged in special operation, and extensive market, price advantage are obvious。When scorching summer or life and work in the environment of warm, wear one there is contact coldness, clothes that ventilation is big seems increasingly important。
Japanese Patent Laid-Open 10-266041 publication describes a kind of least material of height using high-denier-fibre to prepare, but the fibre single thread fiber number used in this material is only 4～6dtex；Additionally number of patent application is a kind of fabric with smooth feeling, refrigerant sense disclosed in CN200810146173.9, use high-denier-fibre and other yarns interwoven to improve the refrigerant performance of fabric, but above-mentioned patent does not all account for the impact on fabric cooling effect of the filamentary special construction。
Summary of the invention
It is an object of the invention to provide a kind of improve the refrigerant sense of fabric, there is special construction add elater and processing method thereof and purposes。
The present invention adds the filament denier of elater more than 7dtex less than 15dtex, and surface has small coil, and coil height is between 0.75～1.0mm, and is distributed as 100～500/m。If adding elater filament number less than 7dtex, itself and object contact surface area will become big, and breathability is bad, does not have refrigerant sense；And adding elater filament number more than 15dtex, the spinnability of precursor is bad。Coil height, less than 0.75mm, adds the frictional force between elater little, is then presented as filoplume, impact weaving more than 1.0mm；Number of coils less than 100/m, then adds the coefficient of friction between elater and improves inconspicuous。Add elater surface there is coil to increase the frictional force between yarn, improve the refrigerant sense preparing fabric。
The elater cross section that adds of the present invention is have 3 profiled-cross-sections with upper groove, and it is had the reeded abnormally-structured voidage adding elater that increases, and improves the breathability of fabric。
The present invention adds elater boiling water shrinkage below 10%, it is preferable that 5%～10%, and flexible return rate CR value is between 5%～25%, it is preferable that 10%～20%。If CR value is lower than 5%, elastic not enough, it is impossible to meet demand；CR value is more than 25%, then the bulkiness of yarn is excessive, and the fabric cooling effect knitted is bad。
The present invention to add its processing method of elater as follows:
By raw material thread (terylene or other dacrons), draw from original silk rack and sequentially pass through hot tank, scroll tube。DTY adds man-hour, and the scope that the first heater temperature is suitable for is between 130～170 DEG C。Scroll tube is disc stack formula scroll tube, and the navel of its use is polyurethane PU dish, and disc stack is combined as 1/3/1, and dish spacing is 0.8mm。Yarn overfeeding laggard enter Network device, blow sth. made by twisting form network by compressing air, finally by spooler, coiling and molding prepares and adds elater。
In the processing method of the present invention, for applicable DTY high speed production process, having selected disc stack formula scroll tube, the navel of its use is polyurethane PU dish, and disc stack is combined as 1/3/1, and dish spacing is 0.8mm。After disc stack number reduces, yarn false twisting twisting count in hot tank can be controlled in below 3100T/M。Combining 1/6/1 processing ratio with disc stack, the coil number that gained adds within the scope of the 0.75～1.0mm of elater surface increases in a large number。After coil increases, the frictional force between yarn becomes big, and when using in woven fabric, the stability of fabric improves。
In the processing method adding elater of the present invention, the compression air of blowout in Network device, more than 0.2MPa。Due to the present invention, to add the filament number of elater big, and compression air is less than 0.2MPa, and interlacing is bad, adds elater obvolvent bad, weaving difficulty。Preferably 0.2～0.5MPa, production cost is relatively low, produces performance preferably。
The all or part of employing present invention adds the fabric that elater is formed, and contact coldness can reach 0.1～0.15J/cm2Sec, ventilation is more than 95cm3/cm2Sec, it is preferable that 95～170cm3/cm2sec。
Detailed description of the invention
Each physical property measurement method of the present invention is as follows:
1. boiling water shrinkage:
The yarn of 10 circles is taken, length L before mensuration process under loading (the 0.1g/D*2* number of turns) state under the tension of 0.1g/D0With length L after process 30min in 100 DEG C of water Celsius, computing formula is: (L0-L)/L0。
2. flexible return rate CR value:
The yarn of 10 circles is taken under the tension of 0.1g/D, measure L1(determine the length under loading+first loading by placing to take out after 20min in 90 DEG C of water Celsius) length under loading at the beginning of L2(), the wherein first loading=2mg/D × number of turns × 2, determining the loading=0.1g/D × number of turns × 2, its computing formula is: the percentage ratio of=(L1-L2)/L1。
3. add the total fiber number of elater:
The elater that adds taking certain length claims its weight to be calculated, and computing formula is: (sampling weight g/ sample length m) × 10000/ adds elater F number。
4. the twisting count that scroll tube provides:
Yarn takes the yarn of its one section of twisting state between the first hot tank end and scroll tube under machining state, calculates the actual twisting count of its 1m length by twist instrument after being measured。
