Abstract

The utility model discloses a terylene fine-denier light net silk. The cross section of a single fiber of the terylene fine-denier light net silk is a crossed or five-leaf-shaped special-shaped cross section. The single fiber of the terylene fine-denier light net silk has the crossed or five-leaf-shaped special-shaped cross section, so more micro voids are formed among fibers, and the capillary phenomenon is enhanced. Therefore, good hygroscopicity is realized, and the single fiber has a larger specific surface area through the special-shaped cross section, so a good ventilation performance is realized.

Description

The light twine of dacron fine-denier

Technical field

The utility model relates to a kind of terylene thread, particularly relates to the light twine of a kind of dacron fine-denier.

Background technology

Along with improving constantly of living standards of the people, people are more and more higher to the requirement of dress ornament, for high-grade clothing, have good hygroscopicity, gas permeability is even more important; But hygroscopicity, the gas permeability of terylene thread commonly used are relatively poor in the dress ornament, make the wearer feel sultry discomfort.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of light twine of dacron fine-denier with good hygroscopicity and gas permeability.

In order to reach above-mentioned purpose, solution of the present utility model is:

The light twine of a kind of dacron fine-denier, the cross section of its single fiber are profiled-cross-sections cross or five blade profiles.

After adopting said structure, the utility model has the light twine of dacron fine-denier to have following beneficial effect: the single fiber of terylene thread has profiled-cross-sections cross or five blade profiles, make to have more fine voids between fiber, aggravated capillarity, therefore have good hygroscopicity; Profiled-cross-section makes single fiber have bigger specific area, therefore has air permeability and good; In a word, the light twine of the utility model dacron fine-denier has characteristics such as fiber number is little, specific area is big, pliability is high, flexibility is good, gloss is soft, has kept terylene initial modulus height again simultaneously, and DIMENSIONAL STABILITY is good, the well-pressed characteristic that is difficult for wrinkle of fabric.

Fig. 2 is the schematic cross-section two of the single fiber of the light twine of the utility model dacron fine-denier.

Among the figure:

Single fiber 1

The specific embodiment

The light twine of dacron fine-denier of the present utility model is composited by many single fibers, the cross section of its single fiber shown in Fig. 1-2, the cross section structure of single fiber 1 mainly contains profiled-cross-sections cross, five blade profiles, yarn count is 40D/72F.

The technological process of the light twine of the utility model dacron fine-denier is as follows:

1, the slice spinning technological process is: and PET (POLYESTER-polyester be called for short PET) section → vibrosieve → pre-crystallization → drying → extrusion molten → melt pre-filtering → static mixing → melt distributes and metering is extruded → and melt thread cooling forming → strand oils → the pre-network of strand → strand coiling (be the POY package, wherein POY is the abbreviation of PRE ORIENTATION YARN (pre-oriented yarn));

Wherein, section requires to be high-class product, by powder and the impurity in the vibrosieve removal section; Pre-crystallization is to improve the degree of crystallinity of section, and bonding putty too early prevents to cut into slices; Remove the section contained humidity by drying, make the section moisture content less than 15ppm; In screw rod extrusion molten process, because flow is less, temperature is set by echelon, and it is temperature required that latter end reaches spinning as far as possible; The prefilter required precision is less than or equal to 15 μ, and spinning temperature is produced slightly high 3-5 ℃ than conventional silk, and the draw ratio of spinnerets should be bigger; Cooling forming adopts ring blowing mode, can make cooling more even; Oil the position than the high 30-50cm of conventional silk production, and the rate that oils is also higher; Add that pre-network helps reeling and unwinding during false twisting; Winding speed will hang down 200-400m/min;

2, false twist texturized technological process is: and balance POY → heating draw texture → network → HEAT SETTING → oil → reel (Draw Tex-tured Yarn, DTY);

Wherein, the purpose of POY balance is to eliminate the strand internal stress, makes the strand internal structure more even, because strand is too thin, its internal structure difference can be bigger in spinning cooling forming process, so equilibration time is at least more than 72H; In heating process, institute's calorific requirement is less relatively, low 15-30 ℃ of heating-up temperature; Even for guaranteeing drawing-off, adopt the drawing-off of drawing-off disc type, if adopt the drawing-off of roller formula, must guarantee the roller contact closely; For reaching false twist texturing effect preferably, adopt soft PU friction disc (PU frictional disk), and for enough false twist tension are arranged, the disc combination is comparatively suitable with the 4-5 sheet; Network is light net, selects the less nozzle in air-flow aperture and Si Dao aperture for use, and network node must be even; Heat setting temperature has no special requirements, and oils to select flatness and the good finish of coherent for use; Because rolling density is bigger, used tubing must have enough intensity, and it is indeformable to guarantee to reel.

The light twine of the utility model dacron fine-denier that makes by above-mentioned technological process, be compared to circular cross-section, fiber number and be generally the conventional polyester silk of dpf 〉=2.0dtex, profiled-cross-sections such as that the light twine of the utility model dacron fine-denier mainly has is cross, five blade profiles, has more fine voids between the fiber, aggravate capillarity, thereby had good hygroscopicity.

The specific area of the single fiber of the light twine of the utility model dacron fine-denier is about 5500cm2/g, is nearly about 4 times of conventional fibre, has bigger surface tension, thereby has air permeability and good.

The fiber number dpf of the light twine of the utility model dacron fine-denier is 0.61dtex, and diameter is 7.5 μ m only, and minimum drop diameter is 100 μ m, therefore has excellent waterproofness.

In sum, the light twine of the utility model dacron fine-denier has stronger capillarity and high surface tension, the fabric that makes so not only has higher hygroscopicity but also has gas permeability preferably, is used for underwear or sportswear, can bring refrigerant comfortable sensation to the wearer; Can also be used to weave high density proofed breathable fabric, nap fabric, mix fine fabric etc., can satisfy comfortable, frivolous, the high-grade requirement of people clothing.

The foregoing description and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.

Claims

1. light twine of dacron fine-denier, it is characterized in that: the cross section of its single fiber is profiled-cross-sections cross or five blade profiles.
