Description

Double-sided absorbent fabric and preparation method and application thereof

Technical field

The present disclosure relates to the field of textiles, for example, to a double-sided absorbent fabric, and a method and application thereof.

Background technique

The water-absorbent fabric refers to a water-absorbent fabric which is woven by a fiber raw material having a water absorbing function and has a function of wiping and bathing, and is mainly used in the fields of indoor bath towels, bathrobes, bathrobes, sports towels, children's clothing and the like. At present, the raw materials used are mainly in two categories: one is to use the natural hydrophilic properties of cotton, hemp and other fabric fibers, which are obtained by knitting the knitting machine to produce the appearance of the terry, and the processing field is the knitting industry; the other is The use of heterogeneous section chemical fibers to increase the water absorption area to improve water absorption performance, processing in the field of knitting, woven industry.

Although the water-absorbing fabric made by the above two types of raw materials has a certain water absorption effect, the disadvantages are obvious. Among them, although the plant fiber fabric has good water absorption effect, it has problems such as fading, imperfection, wear and poor dimensional stability, which increases the use cost and reduces the quality; while the cross-section chemical fiber has a certain water absorption effect, Instead of combining the hydrophilic groups of the fiber material with water, the heterogeneous cross-section structure (non-circular structure) of the chemical fiber of the opposite sex is used to increase the contact area with the water molecules to achieve the water absorption effect, thus the increased contact. The area is limited, and the water absorption and rate are far less than the natural hydrophilic properties of plant fibers. Moreover, in the field of woven fabrics, chemical fibers are often interlaced into a single-sided water-absorbing structure in a bundle-like form, and the water absorption effect is not satisfactory. In order to enhance the water absorption effect, the fabric processed in this manner can only be compensated by adding a hydrophilic agent to the fabric during the post-treatment, but this will cause the water absorption effect in the use to be unsustainable, and since the additive is a chemical, It has certain damage to human skin.

Therefore, how to effectively improve the water absorption of the fabric and avoid adding chemical additives that adversely affect people and the environment in production and processing has become an urgent problem to be solved.

Summary of the invention

Based on the existing problems, the present disclosure provides a double-sided absorbent fabric, for example, providing a double-faced high-absorbent fabric; the double-sided absorbent fabric has high water absorption and a comfortable and soft touch. It is widely used in children's clothing, home bath textiles, and wiping and nursing of high-precision instruments.

The present disclosure adopts the following technical solutions:

In a first aspect, the present disclosure provides a double-sided absorbent fabric comprising warp and weft yarns;

The warp yarn adopts a 50D-150D polyester low-elastic yarn, and the weft yarn adopts a 75D-200D polyester-composite composite microfiber.

In the present disclosure, the warp yarn is a polyester low-elastic yarn, and the weft yarn is a polyester-rubber composite microfiber. The combination of the two has a synergistic effect, which not only enables the fabric to have a strong water absorption property, so that the water absorption reaches 4 g/unit. Above the weight, the water absorption rate is controlled to 18 seconds/unit area or less, and the fabric has excellent stretch resistance and comfortable and soft touch. The outer stretch strength of the fabric can reach 250N (Newton, or more) or 350N. Above (thin/thickness), the effect of the fabric is greatly enhanced.

In the selection of warp yarn materials, the present disclosure adopts polyester low-elastic yarn, which can ensure the fabric fabric has strong tensile resistance, and is used as a surface absorbent material to resist external force stretching and maintain the flat appearance of the fabric; In the selection of the weft material, the present disclosure adopts a polyester-polyamide composite microfiber composed of more than a thousand monofilaments, and the average fineness of the monofilament is about 0.15 dtex (ditex, referred to as decitex), so that the maximum increase can be made. Large floating length; when the monofilament is pulled out and broken by the two sides of the front and back sides, the front and back surfaces of the fabric will show countless slender fluff. At this time, the liquid can be siphoned by the fluff.

The weft yarn passes through the lower part of the warp yarn 1, the warp yarn three and the warp yarn, and is protruded on the upper part of the warp yarn;

The weft yarn 5 is convexly formed on the upper part of the warp yarn 1, the warp yarn 2 and the warp yarn, and passes through the lower portion of the warp yarn;

The weft yarn 6 passes through the lower part of the warp yarn 1, the warp yarn 2 and the warp yarn, and is protruded on the upper part of the warp yarn;

The weft yarn 7 is convexly formed on the upper part of the warp yarn 1, the warp yarn 2 and the warp yarn, and passes through the lower portion of the warp yarn;

The weft yarns are passed through the warp yarns 1, the warp yarns 2 and the lower portions of the warp yarns, and are protruded from the upper portions of the warp yarns.

Alternatively, the five-satin satin structure may be: the warp yarns are warp yarns, warp yarns two, warp yarns three, warp yarns four and warp yarns five from the first side to the second side, and the weft yarns are sequentially from the third side to the fourth side. Weft yarn Yarn 2, weft 3, weft 4, weft 5, weft 6, weft 7, weft 8, weft 9 and weft 10;

The weft yarn passes through the lower portion of the warp yarn and is protruded on the warp yarn two, the warp yarn three, the warp yarn four and the warp yarn five upper portion; the weft yarn two is protruded on the upper part of the warp yarn, and passes through the warp yarn two, the warp yarn three, the warp yarn four and the warp yarn five lower portion; The weft yarn is three-folded on the upper part of the warp yarn 1, the warp yarn two, the warp yarn three and the warp yarn, and passes through the lower portion of the warp yarn; the weft yarn passes through the warp yarn, the warp yarn two, the warp yarn three and the warp yarn lower portion, and is protruded on the upper portion of the warp yarn; The weft yarn 5 is convexly formed on the warp yarn 1, the warp yarn three, the warp yarn four and the warp yarn five upper portion, and passes through the lower portion of the warp yarn; the weft yarn six passes through the warp yarn 1, the warp yarn three, the warp yarn four and the warp yarn lower portion, and is protruded on the upper portion of the warp yarn; The weft yarn 7 is prominently formed on the upper part of the warp yarn 1, the warp yarn 2, the warp yarn 3 and the warp yarn, and passes through the lower part of the warp yarn; the weft yarn passes through the warp yarn 1, the warp yarn 2, the warp yarn 3 and the warp yarn lower portion, and is convexly formed on the upper portion of the warp yarn; The weft yarn 9 is prominently formed on the upper part of the warp yarn 1, the warp yarn 2, the warp yarn 4 and the warp yarn, and passes through the lower portion of the warp yarn; the weft yarn 10 passes through the warp yarn 1, the warp yarn 2, the warp yarn 4 and the warp yarn lower portion, and is highlighted. Three upper warp yarns.

The present disclosure can control the warp and weft float length in a more reasonable range by using four kinds of positive and negative four-dimensional change twill and front and back five-satin structure, and control the ratio of the warp and weft interlacing points to the uninterlaced points. 20 to 25:75 to 80, for example, 20:80, 21:79, 22:78, 23:77 or 25:75, etc., that is, the area of 75% to 80% of the surface of the fabric is covered by the polyester/polyamide composite microfiber. In this way, the fabric can ensure the tightness of the fabric while satisfying the high water absorption effect; the whole fabric can be processed into a garment or a wiping product when compared with the five-tone variation of the front and back, or the six-satin structure of the front and back. The size is more stable and the stretch resistance is stronger.

The fabrics of the present disclosure have the advantages of using positive and negative varying twill or satin structures in:

1) Looseness: The use of a twill or satin structure with a certain length of weft yarn makes the fabric interlacing point greatly reduced, which is more conducive to the penetration of liquid water molecules while ensuring the tightness of the fabric;

2) Easy to nappe: Since the weft yarn adopts polyester/polyamide composite microfiber raw material composed of a plurality of monofilaments, the length of the weft yarn floating length on each side has a great influence on the difficulty of mechanical flocking. The longer the float length, the easier it is for the pile metal steel needle to pull the fiber out and break, and the more monofilament inside the fiber is more easily exposed, so that the more feathers produced by the fiber, the denser the distribution on the fabric surface, so that Liquid water molecules and more microfiber monofilaments can fully contact and produce a siphon phenomenon to achieve high water absorption of the fabric;

3) It is easy to produce a soft touch: using a positive or negative twill or satin structure, the ratio of the interlaced and uninterlaced points of the warp and weft is 20 to 25:75 to 80. In layman's terms, the fabric surface is 75% to 80. The % area is covered by microfibers. After the post-treatment, the surface of the fabric is completely covered with polyester and brocade. The superfine fiber is covered with water-absorbent hairiness, which not only ensures the fabric's full absorption of liquid water molecules, but also achieves a comfortable and soft touch, achieving a perfect combination of functionality and comfort.

The positive and negative four-change twill structure used in the present disclosure has two water absorption faces, and the texture (also called the structure) of each face is the same, and four broken twill are used, and the so-called "broken" refers to an unconventional 3/1 twill structure, the oblique direction of the 3/1 twill structure is reversed in the middle to prevent the grain from being directional, and the resulting hairiness is more uniform, and the four-eighth latitude is a cyclic structure.

The five-satin satin structure used in the present disclosure also has two water-absorbing surfaces, and the texture (also called the structure) of each surface is the same, and all have five satin patterns, and the five-week and ten-weft are a circular structure.

In the above two structures, the double-sided twill structure is relatively straight, and the double-sided satin structure is relatively soft, which can meet various needs in the fields of children's clothing, home bath textiles, and wiping and nursing of high-precision instruments.

In the present disclosure, the warp yarn in the double-sided absorbent fabric adopts 50D (denier) to 150D polyester low-elastic yarn, and may be, for example, 50D, 60D, 70D, 75D, 80D, 90D, 100D, 120D or 150D.
