Abstract
The utility model provides a four-T hollow-type polyester staple fiber and a spinneret plate thereof. The cross section of a fiber hole of the spinneret plate is in a hollow four-T shape where every two of four T-shaped holes are connected with each other and then perpendicularly intersect with each other, the size and shape of the four T-shaped holes are identical, the cross piece of each T-shaped hole is arc-shaped, i.e., half-round, the length of the cross piece of each T-shaped holes is 0.20mm-0.60mm while the width thereof is 0.03mm-0.12mm, the length of a vertical piece of each T-shaped hole is 0.18mm-0.52mm while the width thereof is the same as that of the cross piece, the length of each four-T hollow-type fiber hole is 0.42-1.28mm, the number of the fiber holes is 1000-2500, and convention taper guide holes are adopted. Fibers with the four-T hollow-type cross section are produced through matched spinning and drafting processes; and with existence of the irregular shape and the cavity, the fiber products have excellent performance of both four-T type fibers and hollow type fibers, and manufactured shell fabrics not only have gloss similar to natural silk, comfortable hand feeling and draping property, but also have warm-keeping and ventilating functions.
Description
Technical field
The utility model relates to a kind of four T hollow type profiled filaments and spinning spinnerets used, particularly polyester staple fiber and spinnerets used thereof.
Background technology
Along with socioeconomic develop rapidly, people constantly improve the requirement of material life, and the wearing comfort of textiles has been proposed to higher requirement.By the analysis to fibre section, people start imitated natural fabric, various profiled filaments have been developed, hollow type fiber is wherein a kind of, and its fibre section has certain cavity vertically, gives warmth retention property and bulkiness that fiber is good, but its gas permeability and poisture-penetrability are poor, and heterotypic fibre has a good gas permeability as cross, therefore, fiber has abnormity concurrently and hollow can realize warmth retention property and gas permeability dual-use function.
Summary of the invention
The utility model provides a kind of spinnerets of four T hollow type silk holes, through supporting spinning and draft process and produce the fiber that its cross section is four T hollow types, for achieving the above object, the utility model spinnerets silk hole Cross section Design following technical scheme:
(1) silk cross section, hole is four T font holes, four T word shapes of the connected formation hollow that intersects vertically between two, four T font hole sizes are identical with shape, T font hole transverse sheet end points is circular-arc, be semicircle, T font hole transverse sheet length a is 0.20mm ~ 0.60mm, and width b is 0.03 ~ 0.12mm, T font hole riser length c is 0.18mm ~ 0.52mm, width is identical with transverse sheet width b, and the length d that forms corresponding four T hollow type silk holes is 0.42mm ~ 1.28mm, adopts conventional taper guide hole;
The arranged distribution in (2) four T hollow type silk holes is: on spinnerets, be multilayer concentric circle and distribute, adjacent holes spacing equates;
(3) spinneret orifice on spinnerets is 1000～2500 holes.
The beneficial effects of the utility model are, owing to having adopted the spinnerets in four T hollow type silk holes, change fibre section shape, make the fibre section being spun into be four T hollow shape, due to abnormity and the existence of cavity, make premium properties that this fiber product has four T-shaped fibers and doughnut concurrently in one, the fabric of making not only has the gloss that is similar to silk, comfortable feel and drapability, have warming and airing function concurrently.Meanwhile, the fiber number of fiber can be reduced to below 1.33dtex, and this four T hollow type fibers have changed the wearability of terylene completely, and performance is better than common profiled filament.
