Abstract

The utility model provides a spinneret with cross type spinning hole. The four end points of the spinneret spinning hole are semicircular, the spinning hole consists of two linear type holes which are vertically crossed with each other, and the geometric position of the spinning hole on the spinneret is that: the included angle between the central shaft line of one of the linear holes and the tie line of the central point of the spinning hole 'P' and the circle center of the spinneret 'O' is Alpha. The spinneret with cross type spinning hole can change the cross section of Terylene fiber and produce a plurality of fine grooves on the surface of the fiber, thereby bringing about excellent moisture absorption and leading-out functions due to a wicking effect which completely changes the wearability of Terylene, thereby functions of moisture leading-out, sweating, dryness and comfort replace feelings of skin stuffiness and airtightness.

Description

The spinnerets in a kind of cross silk hole

Technical field

The spinnerets in cross silk of the present utility model hole relates to the synthetic fiber production field in the textile industry, particularly the production equipment field of polyester staple fiber.

Background technology

The hydrophobicity of terylene has two property, and in the chemical fibre early stage of development, the easy wash and wear of dacron is used as advantage and praises, but the bad drenched wet comfortableness of taking of giving again of leading is brought contradiction.Along with rapid development of social economy, people constantly improve the requirement of material life, textiles, and particularly the wearing comfort of a large amount of chemical fibre textiles has become consistent pursuit.Wet fiber is by adopting the spinnerets in cross silk hole, change the fibre section shape, make the fiber surface that is spun into produce many trickle grooves, spin or with after cotton, hair, silk, fiber crops or the other kinds chemical fibre blending wet fiber is pure, in yarn texture, form intensive capillarity, because wicking capillaceous, so produce good moisture absorption, wet guiding function, this effect has changed the wearability of terylene fully, original sultry, the air-locked sensation of skin, and, perspire wet, dry and comfortable, the comfortable replacement by present leading.

Summary of the invention

The purpose of this utility model provides the spinnerets in a kind of cross silk hole, and this spinnerets is produced its cross section through supporting spinning and draft process and is cross fiber product; The lining that is spun out by this fiber product has moisture absorption, wet guiding function.

Spinnerets silk of the present utility model hole Cross section Design is the cross-hole shape that two yi word pattern holes intersect vertically and constitute, and four ends in cross silk hole are circular-arc, are semicircle, and diameter is the width in yi word pattern aperture.Spinnerets is circular, design is evenly equipped with 1000～3000 silk holes on the whole spinnerets, be evenly distributed on the spinnerets, the aperture length of two yi word patterns in silk hole is 0.3mm～1.5mm, width is 0.04mm～0.16mm, angle is the α angle between the central axis in a wherein yi word pattern hole of cross-hole and the central point " P " of cross-hole (i.e. the central axis in two yi word pattern holes intersect vertically intersection point) and spinnerets central point (being round dot) " O " line, and the α angle is 15 °～75 °.

The beneficial effects of the utility model are, owing to adopted the spinnerets in cross silk hole, change the fibre section shape, make the fiber surface that is spun into produce many trickle grooves, because wicking capillaceous so produce good moisture absorption, wet guiding function, has changed the wearability of terylene, the water absorption of fabrics of wet fiber is higher 5～6 times than conventional polyester fabric, and is better than pure cotton fabric.

Among the figure: the central point " P " of silk hole 1, yi word pattern 2, yi word pattern 3, spinnerets round dot " O ", cross-hole

The specific embodiment

Embodiment 1:

When producing the 2.22dtex staple fibre, the concrete size of its spinneret orifice is as follows:

The intersect vertically aperture length of two yi word patterns of the cross-hole that constitutes of two yi word pattern holes is 1mm, and width is 0.1mm.

The geometric position in silk hole is determined: described cross silk hole is to be 30 ° of angles between the central axis in a wherein yi word pattern hole of cross-hole and the central point of cross-hole (i.e. the central axis in two yi word pattern holes intersect vertically intersection point) and the spinnerets central point line in the geometric position on the spinnerets.

Silk hole count on the spinnerets is 1200 holes.

The process technology of spinnerets is common prior art.

Embodiment 2:

When producing the 1.67dtex staple fibre, the concrete size of its spinneret orifice is as follows:

The intersect vertically aperture length of two yi word patterns of the cross-hole that constitutes of two yi word pattern holes is 1mm, and width is 0.8mm.

The geometric position in silk hole is determined: described cross silk hole is to be 15 ° of angles between the central axis in a wherein yi word pattern hole of cross-hole and the central point of cross-hole (i.e. the central axis in two yi word pattern holes intersect vertically intersection point) and the spinnerets central point line in the geometric position on the spinnerets.

Silk hole count on the spinnerets is 1200 holes.

The process technology of spinnerets is common prior art.

Embodiment 3:

The intersect vertically aperture length of two yi word patterns of the cross-hole that constitutes of two yi word pattern holes is 0.8mm, and width is 1.0mm.

The geometric position in silk hole is determined: described cross silk hole is to be the 45 degree between the central axis in a wherein yi word pattern hole of cross-hole and the central point of cross-hole (i.e. the central axis in two yi word pattern holes intersect vertically intersection point) and the spinnerets central point line in the geometric position on the spinnerets.

Silk hole count on the spinnerets is 1500 holes.

The process technology of spinnerets is common prior art.

The spinnerets in a kind of cross silk of the present utility model hole is not limited to above embodiment.
