Abstract

The utility model discloses a PTT collateral fiber, which consists of a PTT fiber and a PET fiber spirally twisted with each other, wherein both the PTT fiber and the PET fiber have a crisscross cross section. The collateral fiber can be used as weft yarn for preparing shirts, jackets and jeans, and can keep the shape memory function of the PTT fiber on the basis of good rebound resilience, so that the products can be easily dealt with. The collateral fiber also has excellent moisture absorption and fast dry functions, and particularly suits the development of novel knitted fabrics. The collateral fiber has the advantages of good coloration and high dye doping, and can achieve double colors on the basis of union dyeing, so as to form fabrics with different styles. In addition, the fiber also has the advantages of good comfort, softness, and bulkiness, and the fiber fabric subjected to napping and grinding treatment has a unique style. The clothes made of the collateral fiber can expand when applied with stress so as to prevent the skintight bondage feeling of elastic spandex fabrics and provide comfort for users.

Description

A kind of PTT collateral fiber

Technical field

The utility model relates to a kind of parallel composite fiber, particularly a kind of PTT collateral fiber.

Background technology

Along with the develop rapidly of textile industry, fabric panel has also welcome their New Times, and people are also more and more higher to the requirement of modern fabrics, and is also more and more to the feature request of function aspects.More powerful, comfortableness and higher-quality lining kimonos are dressed up the important goal of being pursued for lining and clothes practitioner.

Collateral fiber claims conjugate fibre again, in the filament of same endless, along fiber axis to the condensate that exists two or more simultaneously.It has the performance of each component of forming composite fibre simultaneously, and has the good characteristic of composite fibre, is that the employing physical modification makes the chemical fibre simulation and surpasses one of important means of natural fabric.Therefore, development of new has more that the composite fibre of powerful and comfortableness has remarkable economical and technical meaning.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of novel PTT collateral fiber, and it has excellent elasticity crimp property, moisture absorption and quick-drying energy.

For solving above technical problem, the utility model is taked following technical scheme:

A kind of PTT collateral fiber, this fiber by ptt fiber and PET fiber curl mutually obvolvent constitute, the section of described ptt fiber, PET fiber is cross.

Described PTT collateral fiber is preferably the low-stretch yarn of 50D/36F or 100D/72F.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

1, because the polymer P TT/PET of compound two kinds of different shrinkage factors, make fiber after arrangement is handled later, can obtain having the superior elasticity coiled structure, thereby possess the performance close with the spandex core spun yarn, can be used as weft yarn and be used for shirt, upper garment, drillipg trousers, possessing on the good resilience basis, still keep the ptt fiber shape memory function, easily arrange;

2, the section of ptt fiber and PET fiber is cross, make fiber surface form a large amount of capillary grooves, the diesis structure can form the structure of suction and conducting to greatest extent between fiber, this makes fabric possess good moisture absorption and quick-drying function, is particularly suitable for the exploitation of novel pin knitted fabric;

3, use the part of PTT polyester as conjugate fibre, because the PTT polyester has good DISPERSE DYES chromatophilia energy, thereby improved the dyeing ability of product, because two kinds of polyester have different dyeing speeds and dye-uptake, also can be implemented on the basis of co-bathing dyeing, obtain two-color effect, thereby form the lining of different-style; Simultaneously, the lining of being weaved can be dyed various gorgeous colors.

4, this fiber has good wearing comfort and softness, fluffy characteristic, and is through the fabric lining unique style of napping with the frosted processing, more comfortable, more light and soft than the like fibrous on the present market;

5, dress make by this collateral fiber clothes the time because two kinds of polyester all have the slow-release function of tension force, therefore, during body kinematics, clothing is subjected to stress and just can upholds, and has avoided the constraint sense of elastomeric polyurethane fiber fabric close-fitting vest, gives comfortable sensation.

Description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment.

Fig. 1 is a sectional schematic diagram of the present utility model;

Wherein:

1, ptt fiber; 2, PET fiber.

The specific embodiment

As shown in Figure 1, according to the PTT collateral fiber of present embodiment, this fiber by ptt fiber and PET fiber curl mutually obvolvent constitute, the section of described ptt fiber, PET fiber is cross.The specification of the fiber of being weaved is the low-stretch yarn of 50D/36F, 100D/72F, and its preparation process comprises the steps:

1, with half delustring PTT polyester slice of ormal weight, be delivered directly to the chip drying tower, baking temperature is controlled at 130 ℃, control 4～5.5 hours drying time, the moisture in the test section, reach dry standard after, start spinning equipment screw rod one, carry out slice spinning;

2, with half delustring PET polyester slice of ormal weight, through pre-crystallization, control 130～136 ℃ of pre-crystallization temperatures, 2.5～3.5 hours time, carry out drying then, 155～165 ℃ of control baking temperatures, 5～6.5 hours time, the moisture in the test section, reach dry standard after, start spinning equipment screw rod two, carry out slice spinning.

3, adopt the spinning head with diesis shape spinneret orifice, control lateral blowing temperature is at 20～21 ℃, and humidity is controlled at 65～70%, and air quantity is looked the adjustment of coiling situation.The control winding speed is 2700m/min, the specification of the pre-oriented yarn of being weaved (POY) is 83.3dtex/36f, POY textile technology and process are stable normal, through after 24 hours balances, drawn, notice that draft temperature is controlled at below 145 ℃, obtain the bi-component odd-shaped cross section PTT collateral fiber low-stretch yarn of the good moisture absorption sweat discharging functions of possessing of 50D/36F.

To sum up, because the polymer P TT/PET of compound two kinds of different shrinkage factors, make fiber after arrangement is handled later, can obtain having the superior elasticity coiled structure, thereby possess the performance close, can be used as weft yarn and be used for shirt, upper garment, drillipg trousers, possessing on the good resilience basis with the spandex core spun yarn, still keep the ptt fiber shape memory function, easily arrange; Owing to use spinneret orifice with diesis cross section, make fiber surface form a large amount of capillary grooves, the diesis structure can form the structure of suction and conducting to greatest extent between fiber, this makes fabric possess good moisture absorption and quick-drying function, is particularly suitable for the exploitation of novel pin knitted fabric; Use the part of PTT polyester as conjugate fibre, because the PTT polyester has good DISPERSE DYES chromatophilia energy, thereby improved the dyeing ability of product, because two kinds of polyester have different dyeing speeds and dye-uptake, also can be implemented on the basis of co-bathing dyeing, obtain two-color effect, thereby form the lining of different-style; Simultaneously, the lining of being weaved can be dyed various gorgeous colors.This fiber has good wearing comfort and soft, fluffy characteristic, and is through the fabric lining unique style of napping and frosted processing, more comfortable, more light and soft than the like fibrous on the present market; During clothes that dress is made by this collateral fiber, because two kinds of polyester all have the slow-release function of tension force, therefore, during body kinematics, clothing is subjected to stress and just can upholds, and has avoided the constraint sense of elastomeric polyurethane fiber fabric close-fitting vest, gives comfortable sensation.
