Description

Elastic-resilience super-water-absorption terry fabric with hand feeling and production method thereof

Technical Field

The invention belongs to the field of towels, and particularly relates to a resilient super-absorbent terry fabric with rich hand feeling and a production method thereof.

Background

As the fabric having the loop, for example, a towel is exemplified. The warp threads of the weave are divided into two systems, one system being taut and the other system being loose, the warp threads of the loose system being loose in a looped manner, thereby forming terry loops. Since the loop is endless, there is a gap between the yarns, and therefore, the loop contains much air and has moderate elasticity. By having the loop, the towel has excellent water absorption, heat retaining property, air permeability, skin touch, and the like.

With the continuous development of social economy, the requirements of consumers on commodities are higher and higher, the use performance of towel products serving as daily necessities is more and more concerned by people, most of the traditional towel products are well known by consumers, and common weak twist products are fluffy and soft in hand feeling, but lack of resilience, have a lot of hairiness and relatively high hair loss after washing and are difficult to meet the comfortable requirements of the consumers on the use of the products. In recent years, the latex towel with the resilience hand feeling is fluffy and soft in hand feeling, has resilience when being held in hands, and is good in water absorption, but most of the towels are formed by sewing and compounding latex as a core and towel cloth or other fabrics as surface layers, are not easy to fold and manage, have long production process and high production cost, and cannot be accepted and accepted by consumers as a popular product.

Disclosure of Invention

Aiming at the technical problems, the invention provides a super-absorbent terry fabric with rich hand feeling and resilience and a production method thereof, the terry yarn of the terry fabric is formed by blending 1.3 polytrimethylene terephthalate fiber and cotton fiber according to a certain proportion, then the terry fabric is warped and sized, and then a towel blank is formed by adopting a towel loom or a weaving machine, and finally a series of dyeing and finishing processes are carried out to obtain the characteristics that the terry fabric has rich hand feeling and elasticity, the terry yarn has a microporous structure, the water absorption of the terry fabric can reach more than 90 percent, the low molting rate is ubiquitous, and the hand feeling after washing is good.

The technical scheme of the invention is as follows:

the super water-absorbing terry fabric with hand feeling and resilience has 1.3 wt% of polypropylene glycol terephthalate fiber and 70-95 wt% of cotton fiber.

Preferably, the weight percentage of the poly 1.3 propylene glycol terephthalate fiber is 7 percent to 15 percent, and the weight percentage of the cotton fiber is 85 percent to 93 percent. The research of the inventor finds that if the PTT fiber content is lower than 7%, after the product is dyed, the resilience of the looped pile is insufficient, the molting rate is improved to a limited extent, and if the PTT fiber content is higher than 15%, the looped pile shrinks seriously, the bulkiness is reduced greatly, and the product feels stiff.

Preferably, the terry yarn is a blended yarn of 1.3 trimethylene terephthalate fiber, cotton fiber and other fibers, wherein the weight percentage of the 1.3 trimethylene terephthalate fiber is 5% -30%, the weight percentage of the cotton fiber and the other fibers is 70-95%, the cotton fiber and the other fibers are mixed in any proportion, and the other fibers are one or more of flax fiber, hemp fiber, viscose fiber, modal, lyocell, terylene and acrylic fiber in any proportion. The addition of other fibers is beneficial to improving the hand feeling and the luster, and simultaneously, the quick-drying performance of the product is improved.

Preferably, the looped yarn is blended by fiber blending or drawing blending.

Preferably, the terry yarn metric twist multiplier is: 220-: 8.8-15.0cm/10 loops; further preferably, the terry fabric has a terry yarn metric twist multiplier of: 250-: 10.5-14.0cm/10 loops.

A production method of a super loop-absorbing fabric with hand feeling and resilience comprises the following steps: padding, desizing, polishing and bath, bleaching, dyeing and softening, and the specific process comprises the following steps:

padding; soaking with a single padder or long padder; the method mainly aims at pre-shaping the looped pile, and the looped pile can be kept smooth in a wet state after padding so as to ensure that the height of the looped pile is uniform and consistent during high-temperature shrinkage and avoid the situation that the looped pile excessively spirals to cause small pits on the loop surface;

the desizing and polishing one-bath process comprises the following steps: the polishing enzyme is selected from the neutral gentle enzyme of Nuoweixin 8000L, and the dosage (owf): 0.05-0.3%, pH 6.5, treatment conditions: 55 degrees x45 min; adding novacin alpha-amylase without adding water: 1g/l, discharging water after 80 degrees and 20 min;

the bleaching process comprises the following steps: the specific bleaching process is as follows: hydrogen peroxide with mass concentration of 27.5 percent: 5-10g/l, 32% caustic soda by mass concentration: 5-8g/l, refining agent: 1 to 2g/l of JN-98, hydrogen peroxide stabilizer: 0.15-3g/l, treatment conditions: 98-110 degrees x60 min; the overflow machine bleaching process is adopted, which is more beneficial to the filling power and the rebound resilience of the product terry,

the dyeing process comprises the following steps: the medium and light color (the color depth is less than 2 percent) adopts a conventional dyeing process, only cotton is dyed, PTT fiber is not dyed, namely, reactive dye is adopted, and 60-degree dyeing is carried out; if the color is dark (the color depth is more than 2 percent), the PTT fiber needs to be dyed so as to avoid a white point caused by the PTT fiber. At the moment, two-bath two-step dyeing is needed, wherein PTT fiber is dyed by adopting a conventional disperse dye under an acidic condition (the PH is generally controlled between 4 and 6) for 30 to 60 minutes at 110 ℃, then reduction cleaning is carried out (the process conditions are as follows: caustic soda (32%): 1g/l, sodium hydrosulfite: 2g/l 85 ℃ x10 to 15 minutes), then warm water washing is carried out, and then cotton is dyed according to the dyeing process of the reactive dye.

The softening process comprises the following steps: the softening agent is a hydrophilic softening agent for softening, and the softening process comprises the following steps: 35 degrees x30 min.

The softener is available from fatty amide softener DT530 produced by Federal kort in Hebei.

The bleaching process is one of the key elements of the invention: the PTT fiber can be stably contracted at the temperature of 98-110 ℃, the PTT fiber in the looped pile is contracted in a bleaching bath, the pure cotton fiber or other fibers in the looped yarn are not contracted, the cotton fiber or other fibers at the periphery of the looped yarn are passively bent in the contraction process of the PTT fiber, micropores are formed on the surface of the yarn, the key points of rebound resilience hand feeling and super water absorption performance are realized, the low molting rate is realized because the contraction of the PTT fiber drives the cotton fiber or/and other fibers to be passively contracted, after the fibers are changed into a bent shape, the cohesive force between the fibers is increased, and the fibers are not easy to fall off from a yarn main body, so the molting rate is low.

The terry yarn of the terry fabric is an experienced terry fabric which is prepared by blending 1.3 polytrimethylene terephthalate (PTT) fiber with cotton fiber or/and other fibers according to a certain proportion, then warping and sizing the yarn, then adopting a towel loom or weaving the yarn into a blank towel, and finally carrying out a series of dyeing and finishing processes to obtain the terry fabric which is rich in hand feeling and elasticity, rich in microporous structure, excellent in water absorption performance and low in molting rate.

Compared with the traditional pure cotton or blended looped pile fabric, the looped pile fabric manufactured by the invention has the characteristics of hand feeling rich in resilience, water absorption of more than 90 percent, low molting rate which is 0.5-1.5 thousandth lower than that of the common pure cotton looped pile fabric after 5 times of washing, and good hand feeling after washing.
